Business Owner? 5 Overlooked Tax Deductions
Business Owner? 5 Overlooked Tax Deductions 266 266 Noelle Merwin

If you’re self-employed, you probably have questions about deducting business expenses on your federal income tax return. Here’s a quick overview of the filing requirements for sole proprietors and independent contractors, and five examples of expense deductions that are commonly overlooked or misunderstood.

Filing basics

Sole proprietors and independent contractors must report their business activity on Schedule C, “Profit or Loss From Business,” of their personal tax returns (Form 1040). Business income includes money earned from customers, side gigs, online sales and other self-employment activities. Income may be reported on Forms 1099-NEC or 1099-K, but you must report all taxable business income, even if you don’t receive a tax form.

Although employees can no longer deduct unreimbursed business expenses, self-employed individuals can offset their business income with various deductions for business-related expenses. This is a major tax advantage for the self-employed.

When evaluating whether costs are deductible, follow this golden rule: Business expenses must be ordinary (common in your industry) and necessary (helpful and appropriate for the business). Of course, you’ll need to keep detailed records to support your business deductions. Obvious examples of potentially deductible expenses are supplies, materials, and, if you have employees, payroll and benefits. Other business-related expenses may also be deductible on Schedule C, though the rules are sometimes confusing. Below are five common examples.

  1. Home office

Unlike employees who work remotely, you can deduct the costs for a workspace in your home that’s used regularly and exclusively as your principal place of business. This can include a portion of actual indirect home expenses — such as rent or mortgage interest, insurance, utilities and repairs — based on your business-use percentage. For instance, if you use 10% of your apartment’s square footage for business, you can deduct 10% of your rent.

You can also fully deduct direct expenses (for example, the cost of painting your office) and, if you own your home, claim a depreciation allowance under IRS tables. In lieu of tracking your actual expenses, the IRS also offers a simplified method of $5 per square foot for up to 300 square feet.

  1. Education

The costs of refresher courses, continuing education classes, vocational training and other education programs may be deductible if you’re required to take them to maintain or improve skills required for your current trade or business. Qualifying expenses include tuition, books, supplies and fees, and potentially travel costs to attend education programs.

However, costs of education that’s needed to meet the minimum requirements for a trade or business or that qualifies you for a new trade or business generally aren’t deductible. For example, you can’t claim the cost to obtain an undergraduate degree as a business expense.

  1. Business meals

You generally can deduct 50% of the costs of business meals if they aren’t “lavish or extravagant.” This applies to food and beverages provided to customers, clients, suppliers, employees, agents, partners or professional advisors — whether established or prospective.

Although entertainment costs aren’t deductible under current law, food and beverages might be deductible even if they’re provided at a nondeductible entertainment activity. But such a deduction is available only if:

  • The food and beverage items are separately purchased or identified from the entertainment costs on bills, invoices or receipts, and
  • The amount charged for food or beverages reflects the venue’s usual selling price for those items if purchased separately from the entertainment or approximates the reasonable value of those items.

Say, for example, that you take a customer to a World Cup match this summer. The ticket costs aren’t deductible. But if you buy the customer popcorn, nachos and drinks while there, you can deduct half of those costs as long as you have proper documentation, such as the itemized receipt, and records showing who attended and the business purpose.

  1. Business travel

If you travel to a temporary location for business purposes, you can deduct your travel expenses, including round-trip airfare, hotel costs and other incidentals (such as tips and cab fares). However, the primary purpose of your trip must be business related. For instance, you might travel to a different city or country to attend a trade show or educational conference.

Beware: Some allocations may be required if a trip combines business and pleasure — for example, if you fly to a location for four days of business meetings and stay for an additional three days of vacation. Only the reasonable cost of lodging and 50% of meals incurred during the business days are deductible. Lodging and meal costs incurred for the personal vacation days aren’t deductible.

On the other hand, with respect to the cost of the travel itself (for example, plane fare), if the trip is primarily for business purposes, the travel cost can be deducted in its entirety, and no allocation is required. Conversely, if the trip is primarily personal, none of the travel costs are deductible.

If your spouse joins you, his or her travel expenses generally aren’t deductible, unless your spouse is your employee and has a bona fide business reason to be there. But the restrictions apply only to additional costs incurred by having your nonemployee spouse travel with you. For example, the expense of a hotel room or for traveling by car would likely still be fully deductible because the cost to rent the room or travel by car alone vs. with another person would be the same, even in a rented car.

  1. Business vehicle expenses

If you drive your personal vehicle for business purposes, you may be eligible to deduct some auto-related expenses on Schedule C. The amount of your deduction is based on the percentage of business use.

For example, suppose you use your car 60% for business driving in 2026. That means you can deduct 60% of your vehicle costs — such as gas, repairs and insurance — plus a generous depreciation allowance, subject to certain limits for “luxury cars.” And, if you buy the vehicle in 2026, you may also qualify for a Section 179 deduction and 100% bonus depreciation, subject to applicable eligibility requirements and limitations.

Be aware that the IRS is a stickler for documentation. Briefly stated, you must keep a contemporaneous log listing every business trip and proof of your expenses. Alternatively, you can cut down on recordkeeping by using the standard mileage rate of 72.5 cents per business mile (plus business-related tolls and parking fees) in 2026.

Don’t leave tax savings on the table

Many self-employed taxpayers miss legitimate deductions because they fail to keep adequate records or misunderstand the rules. Tracking expenses throughout the year can make tax filing easier, help ensure you don’t miss legitimate deductions and strengthen your position if the IRS questions a deduction.

After-Tax vs. Roth 401(k) Contributions: Which Strategy Fits You?
After-Tax vs. Roth 401(k) Contributions: Which Strategy Fits You? 266 266 Noelle Merwin

If you participate in a company 401(k) plan, you already know that you can make pre-tax contributions up to the annual elective deferral limit to a traditional, tax-deferred account. If your 401(k) plan offers a Roth option, you can use part or all of your limit to make after-tax contributions to a Roth account instead. But you may have a third option, if your 401(k) plan allows it: Make after-tax contributions to a traditional account.

Traditional vs. Roth deferrals

For 2026, 401(k) elective deferral contributions are generally limited to $24,500. If you’ll be 50 or older at year end, you can make additional elective deferral contributions, called “catch-up” contributions. The 2026 catch-up contribution limit is either $8,000 or $11,250, depending on your age. However, if your 2025 salary exceeded $150,000, any catch-up contributions must be made to a Roth 401(k) account.

When you make pre-tax elective deferrals to a traditional 401(k), the contributions aren’t included in your taxable income for the year, but they’re still subject to Social Security and Medicare taxes (collectively called FICA tax). The account funds can grow on a tax-deferred basis, and you’ll owe income taxes on distributions — both those attributable to contributions and those attributable to growth.

When you make after-tax Roth 401(k) elective deferrals, the contributions don’t reduce your taxable income. So, they’re subject to both income tax and FICA tax. The payoff is that earnings in your Roth 401(k) account are allowed to accumulate income-tax-free and you can take income-tax-free qualified withdrawals from the account once you meet the requirements. (Generally, qualified distributions are those after age 59½ if the account has been open at least five years.)

How after-tax contributions are different

If your 401(k) plan allows non-Roth after-tax contributions, they’re treated as part of your taxable wages. Therefore, these contributions are subject to income tax and FICA tax. You may owe state and local income taxes, too. Because they don’t go into a Roth account, they aren’t eligible for all the tax benefits Roth accounts offer.

So, you might be thinking, “why would I want to make after-tax contributions?” The answer is to get more money into your 401(k) account, where it can accumulate income and gains without being taxed until you start taking withdrawals. These contributions aren’t subject to the annual elective deferral limit. So you can make them after you’ve maxed out that limit, including catch-up contributions, if applicable.

However, there’s still a limit on total additions that can be made each year to your 401(k). Including your elective deferrals (except for any catch-up contributions), your after-tax contributions and any employer contributions, 2026 contributions can’t exceed the lesser of: 1) $72,000 or 2) 100% of your compensation.

Also, after-tax contributions create tax basis in your account, which means that the after-tax amount contributed can eventually be withdrawn tax-free. (But withdrawals attributable to growth on that amount will be taxable, a significant difference from qualified Roth distributions.)

After-tax contributions in action

To illustrate how these contributions work, here’s an example: Let’s say your employer sponsors a 401(k) plan with a 50% company match, your 2026 salary is $150,000 and you’re under age 50. The plan allows employees to make after-tax contributions. You max out your elective deferral limit by contributing $24,500 to your traditional 401(k) account. Your employer makes a matching contribution of $12,250. That means you’re allowed to make up to $35,250 in after-tax contributions ($72,000 – $24,500 – $12,250) this year. You decide to make $10,000 of after-tax contributions.

  • Your $24,500 of elective deferral contributions aren’t included in your taxable wages for federal income tax purposes but they are subject to FICA tax withholding.
  • Your employer’s $12,250 matching contribution is exempt from federal income tax and FICA tax.
  • Your $10,000 after-tax contribution is included in your taxable income and is subject to federal income tax and FICA tax. But it creates $10,000 of tax basis in your 401(k) account, which can be withdrawn tax-free.

Be aware that 401(k) plans are subject to complicated nondiscrimination rules intended to prevent plans from operating in favor of highly compensated employees as opposed to rank-and-file workers. In most cases, nondiscrimination rules won’t impact the ability of an employee to make after-tax contributions, but there may be exceptions.

Beyond elective deferrals

If you’ve been maxing out your elective deferrals, after-tax 401(k) contributions can be a tax-efficient way to add to your retirement nest egg. We can review your situation and help you determine whether you might benefit.

Self-employed? Don’t overlook a Roth IRA
Self-employed? Don’t overlook a Roth IRA 266 266 Noelle Merwin

Some small business owners overlook Roth IRAs because they assume their income is too high for them to qualify to make Roth contributions. Others may think their current tax rate is higher than it will be in retirement, making current tax deductions more valuable than future tax-free distributions. However, if you don’t at least consider contributing to a Roth IRA, you may be missing a potentially valuable tax-saving opportunity.

Rules and restrictions

Roth IRA contributions aren’t deductible, but they’re beneficial because you reap tax savings on the back end. (More on that later.) For 2026, the annual contribution limit is $7,500 (up from $7,000 for 2025). If you’ll be 50 or older by the end of the tax year, you can make an additional $1,100 catch-up contribution. The same limits apply to traditional IRAs, and your Roth IRA limit is reduced by any traditional IRA contributions you make for the year.

But your ability to make Roth IRA contributions is phased out if your modified adjusted gross income (MAGI) exceeds certain levels. For 2026, the phaseout ranges are:

  • $153,000 to $168,000 for single individuals and heads of households, and
  • $242,000 to $252,000 for married couples filing jointly.

If your MAGI falls within the range, your contribution limit is reduced. If it equals or exceeds the top of the range, your ability to contribute is eliminated.

Married individuals who file separately and live apart for the full year are treated as single individuals for the income limitations. However, separate filers who live together at any time during the year are subject to a phaseout range of $0 to $10,000.

Is your income too high to qualify?

At first glance, these figures may cause you to assume you’re ineligible for Roth contributions. But take another look.

When calculating MAGI for Roth IRA eligibility purposes, self-employed individuals may be able to significantly reduce their taxable income through deductions for:

  • Certain business expenses, such as rent, home office expenses and computer costs,
  • Contributions to a tax-deferred retirement plan, such as a solo 401(k), SEP IRA or SIMPLE,
  • Health insurance premiums, and
  • Self-employment tax.

These deductions, along with others, are subtracted when calculating MAGI. Therefore, a self-employed person can have relatively high gross income from his or her business while having a much lower MAGI.

The choice between contributing to a Roth IRA or a tax-deferred account isn’t an all-or-nothing proposition. Depending on your situation, you may decide to contribute to both types of accounts, subject to applicable limits. Contributing to a tax-deferred retirement plan provides immediate tax savings. And, because these contributions lower your MAGI, they may put your taxable income below the phaseout limits for Roth IRA contributions.

Additional benefits

The main upside of contributing to a Roth IRA is that qualified withdrawals won’t be taxed. This can be advantageous if you expect to be in a higher tax bracket in retirement or if tax rates increase. Moreover, withdrawals from Roth accounts aren’t counted when calculating the taxable portion of your Social Security benefits.

Another Roth IRA advantage is that you don’t have to take withdrawals at any age, meaning the account can continue to grow tax-free. With a traditional IRA (and other tax-deferred retirement accounts), at age 73, you generally must begin to take required minimum distributions or face a penalty equal to 25% of the amount you should have withdrawn but didn’t. In addition, if your Roth IRA is passed on to your heirs, it can continue to grow tax-free, and their withdrawals generally will be tax-free. However, most nonspouse beneficiaries will be required to deplete the account within 10 years of inheriting it.

Bottom line

A Roth IRA offers many potential benefits, and self-employed individuals may be more likely to qualify to make Roth IRA contributions than other taxpayers with similar gross incomes. But they aren’t right for every situation. We can help evaluate your eligibility and develop a long-term retirement strategy that aligns with your personal and financial goals.

Tax News: Amending Personal Income Tax Returns
Tax News: Amending Personal Income Tax Returns 266 266 Noelle Merwin

It is estimated that five million amended income tax returns are filed with the IRS annually. There are various circumstances why an amended Federal income tax return is filed by an individual taxpayer including:

•    To correct an error discovered after filing
•    Receipt of a corrected 1099 form, often from brokerage firms
•    Receipt of a third-party document such as a K-1 or 1099 form after filing
•    Receipt of an amended K-1 from a trust, estate, partnership or S corporation
•    To carryback credits in certain situations
•    To change one’s filing status – note that one cannot change from married joint to married separate after the due date.

There are circumstances where a Federal amended tax return also leads to the filing of amended state income tax returns. On the other hand, sometimes an amended state income tax return will be filed without the filing of an amended Federal income tax return. Case in point is where a nonresident personal income tax return is audited resulting in an increase in the nonresident tax liability. This often leads to a refund opportunity via the filing of an amended state income tax return for the resident state via claiming an increase in the credit for taxes paid to other jurisdictions.

The general time period for filing an amended income tax return is three years. If the original income tax return was filed prior to April 15 it is deemed filed on April 15. If the original income tax return was filed on extension, the three-year period is measured from the actual filing date. These rules apply not only for Federal purposes but for both New Jersey and New York. To illustrate, if an individual filed their 2022 personal income tax returns without going on extension, those income tax returns are deemed filed April 15, 2023. Thus, the three-year period has just expired. This not only applies to refunds but to tax deficiencies.

The IRS as well as the states have six years to conduct an audit if it is determined that there was an omission of gross income exceeding 25% of the reported gross income. For example, a taxpayer reports $400,000 of gross income. If it determined that there was an omission of income exceeding $100,000 then the statute of limitations becomes six years. Taxpayers cannot use this longer period to file amended tax returns.

Debt vs. Equity: Why the Way Shareholders Fund a C Corporation Matters for Taxes
Debt vs. Equity: Why the Way Shareholders Fund a C Corporation Matters for Taxes 266 266 Noelle Merwin

If you operate your business as a C corporation, how you put money into your company — and how you take it back out — can have a major impact on your tax bill. Payments from shareholders to fund the business can either be classified as capital contributions (equity) or shareholder loans (debt). That might sound like an accounting technicality, but it has real tax consequences because our federal income tax system treats corporate debt more favorably than corporate equity. Put simply, equity can lead to double taxation; loans can help you avoid it.

Why it matters

Companies occasionally need capital infusions. Start-ups need cash to help get the business up and running. And established businesses may need additional funds to pursue growth opportunities or cover short-term cash flow gaps. If your business needs money, you could seek financing from a third-party lender. But for closely held businesses, shareholders are often a more convenient (and affordable) source of financing.

Some closely held C corporations are funded exclusively with equity, but many are intentionally structured with a mix of equity and shareholder loans. Lending money to your corporation can be a tax-smart move over the long run.
That’s because when you later get your money back out of the corporation in the form of loan repayments, the repayments of loan principal will generally be tax-free. Interest payments on a shareholder loan are taxable to you as ordinary income, but the corporation gets an offsetting deduction. In essence, shareholder loans provide a built-in, tax-advantaged mechanism for C corporation owners to get cash out of the business.

In contrast, making a capital contribution (a stock investment) can be costly from a tax perspective. When you later, as an equity investor, want to take cash out of the corporation, the withdrawals may be treated as nondeductible dividends to the extent of the corporation’s earnings and profits. This results in double taxation.
In other words, the corporation already paid income taxes on the profits (at a flat 21% rate), and you as a shareholder must pay individual-level taxes on the dividends. The maximum federal rate on qualified dividends is 20%, but most taxpayers pay 15%. Individuals may also owe the 3.8% net investment income tax (NIIT) on dividends.

How it works

Suppose your C corporation needs a $5 million capital infusion. As the sole shareholder, you ante up with a $2 million capital contribution and a $3 million loan. You execute a formal, written note that specifies the loan terms, including the interest rate, maturity date, any collateral pledged to secure the loan and a repayment schedule.

If the interest rate on your loan to the company equals or exceeds the applicable federal rate (AFR), you’ll avoid federal income tax complications and possible adverse tax results. AFRs can change monthly. In April 2026, the monthly AFR for mid-term loans with terms of three to nine years is only 3.75%. This is significantly lower than the rate you’d get from a third-party lender.
This capital structure allows you to recover $3 million of your investment in the company as tax-free repayments of loan principal. The interest payments give you additional cash from the corporation without double taxation, because your company can deduct the interest.
If you instead supply the full $5 million as a capital contribution and later want to withdraw money, all or part of the withdrawal could be treated as a double-taxed dividend.

For instance, say you withdraw $3 million after a few years, and the entire amount is treated as a taxable dividend. Assuming you’d be subject to the maximum 20% federal income tax rate and the 3.8% NIIT, you’d owe Uncle Sam $714,000 on the withdrawal ($3 million × 23.8%). You could have avoided incurring that tax liability by making a $2 million capital contribution and a $3 million loan to the corporation.

Bottom line

Structuring part of a needed capital infusion as a loan — rather than all equity — can minimize double taxation, giving you a more tax-efficient way to access cash in the future. But this arrangement only works if it’s properly documented and respected as bona fide debt. This includes:

  1. drafting a written promissory note with a stated interest rate and stated repayment dates, and
  2. making timely principal and interest payments. The IRS may reclassify shareholder loans as equity if they’re not properly structured, thereby eliminating the intended tax benefits.

If you’d like to take advantage of this strategy, contact your Smolin representative to explain your options and help you structure the loan to reduce the chance of IRS reclassification.

What to Know When it Comes to Filing Extensions
What to Know When it Comes to Filing Extensions 266 266 Noelle Merwin

Many taxpayers file extension requests that typically extend the deadline for filing their income tax returns by six months, from April 15th to October 15th for personal income taxes. One does not need to have a reason to file extension requests. The extension request pertains to the filing of the tax return as opposed to the payment of any tax owed. Failure to make sufficient payments by the original due date including a payment with the extension request can lead to the imposition of penalties.

For Federal purposes, in order to have a valid extension that avoids any penalties, total payments must equal at least 90% of the actual tax liability. This can be challenging especially for owners of pass-through entities where accurate K-1 income information is unavailable as of April 15th. For those taxpayers who are required to make quarterly estimated tax payments, a first quarter estimated payment for the year in progress is often tacked on to the extension payment to provide a cushion. Any resulting overpayment typically ends up being applied to the subsequent year.

State extension requirements vary by state. New Jersey only requires that 80% of the actual tax liability be paid to avoid incurring penalties. And only if a payment is being made is a NJ extension request required to be filed. New York follows the Federal threshold and requires the filing of an extension request even where no payment is being made. The same rules apply whether one is a state resident or nonresident filer.
If a taxpayer files their personal income tax returns prior to the April 15th due date, their tax returns are deemed filed on April 15 from which point the three year statute of limitations for either filing an amended tax return or for being audited begins. On the other hand, the actual filing date begins the three year statute of limitations for taxpayers on extension.

Filing an extension request generally allows for a delay in making retirement plan contributions until the extended due date. The one exception to this rule pertains to IRA contributions, which must be made by the original due date. Contact your Smolin representative with any questions you may have.

Clean Energy Investments Could Still Pay off at tax time
Clean Energy Investments Could Still Pay off at tax time 266 266 Noelle Merwin

Last year’s One Big Beautiful Bill Act (OBBBA) terminated several clean energy tax incentives earlier than previously scheduled. You may qualify for a 2025 tax credit if you bought an electric vehicle or made eligible green home improvements last year. Remember, tax credits reduce your tax liability dollar-for-dollar (unlike deductions, which reduce the amount of income subject to tax). So tax credits are especially valuable.

Did you buy an electric vehicle?

If you bought an eligible clean vehicle by September 30, 2025, you may be able to claim one of these tax credits on your 2025 return:

New clean vehicle credit. Buyers of new electric and fuel cell vehicles may be able to claim a credit up to $7,500, depending on how the battery components and critical minerals were sourced. Vehicles that meet only one of the sourcing criteria may be eligible for a $3,750 credit. This credit was originally set to expire after 2032. But, under the OBBBA, it expired on September 30, 2025.

The maximum manufacturer’s suggested retail price for a vehicle to be eligible for the credit is $55,000 for cars and $80,000 for SUVs, trucks and vans. The vehicle also must have undergone final assembly in North America. In addition, the credit isn’t allowed for vehicles with any battery components from a “foreign entity of concern.” For you to qualify, your 2025 adjusted gross income (AGI) must not exceed $150,000 ($300,000 if you’re married filing jointly and $225,000 if you’re filing as a head of household).

Used clean vehicle credit. Buyers of used electric or fuel cell vehicles may be able to claim a credit of up to $4,000 or 30% of the purchase price — whichever is lower — if they bought the vehicle from a dealer. Like the new clean vehicle credit, this credit had been set to expire after 2032 but, under the OBBBA, it expired on September 30, 2025.

The maximum purchase price for a vehicle to be eligible for the credit is $25,000. For you to qualify, your 2025 AGI must not exceed $75,000 ($150,000 if you’re a joint filer and $112,500 if you’re a head-of-household filer).

Did you make green home improvements?

If you made certain home upgrades in 2025, you may be eligible for one of these tax credits on your 2025 return:

Energy-efficient home improvement credit. This nonrefundable credit equals up to 30% of qualified expenses to make your home more energy efficient. The maximum credit you can claim for 2025 generally is $1,200. There are no AGI-based limits, but there are credit caps that vary by item. Some examples of 2025 credit limits are $150 for energy audits, $250 per exterior door ($500 total), $600 for windows and $2,000 for heat pumps (superseding the usual $1,200 limit). Before the OBBBA, the law set the credit to expire after 2032.


Residential clean energy credit. This nonrefundable credit equals 30% of the cost of eligible renewable energy systems such as solar, wind and geothermal installations. There generally are no caps or AGI-based limits. Before the OBBBA, the law set the credit to expire after 2034.

Are you eligible for a tax credit?

One more clean energy credit you might be able to claim on your 2025 return is the alternative fuel vehicle refueling property credit. You may be eligible if last year you installed equipment at your home to recharge electric vehicles. The credit equals 30% of the installation cost, up to $1,000 per charging port.

Even if you didn’t install a charging port in 2025, you still have time. Install one by June 30, 2026, and you may be able to claim the credit on your 2026 return next year.

Not sure if you qualify for clean vehicle or green home improvement credits? Contact your Smolin representative.

April 15 Isn’t Just Tax Day: Key Deadlines You Need to Know
April 15 Isn’t Just Tax Day: Key Deadlines You Need to Know 266 266 Noelle Merwin

You know your 2025 federal income tax return is due April 15, 2026. But do you know what else has an April 15 deadline? If you don’t, you could miss out on valuable tax-saving opportunities or become subject to interest and even penalties.

Making 2025 contributions to an IRA

It may be 2026, but you can still make a 2025 contribution to a traditional or Roth IRA until April 15. For 2025, eligible taxpayers can contribute up to $7,000 ($8,000 if they’re age 50 or older). The limit applies to traditional and Roth IRAs on a combined basis.

If you contribute to a traditional IRA, you may be able to deduct the amount on your 2025 income tax return. But if you (or your spouse, if applicable) participate in a work-based retirement plan such as a 401(k) and your income exceeds certain limits, your deduction will be subject to a phaseout.

Roth contributions aren’t tax-deductible, but qualified distributions will be tax-free. Roth contributions are subject to an income-based phaseout, whether or not you (or your spouse) participate in a 401(k) or similar plan. If your Roth IRA contribution is partially or fully phased out, you can make nondeductible traditional IRA contributions instead, assuming you’re otherwise eligible.

Be aware that the 2025 IRA contribution deadline is April 15 regardless of whether you file for an income tax return extension.

Making 2025 contributions to a SEP

If you own a business or are self-employed, you still can reduce your 2025 tax liability by making deductible contributions to a Simplified Employee Pension (SEP) plan by April 15. If you don’t already have a SEP in place, you can contribute for 2025 as long as you set up the plan by the contribution deadline. The 2025 contribution limit is 25% of your eligible compensation up to $70,000 (though special rules apply if you’re self-employed).

Keep in mind that, if you have employees who work enough hours and meet other qualification requirements, generally they must be allowed to participate in the plan. And you’ll have to make contributions on their behalf at the same percentage you contribute for yourself.

If you file to extend your 2025 return, you have until the extended October 15 deadline to set up your plan and make deductible 2025 contributions.

Filing for an automatic six-month extension

If you’re unable to file your individual return by April 15, you generally must file for an extension (Form 4868) by April 15 to avoid failure-to-file penalties. But this isn’t an extension of the tax payment deadline. If you expect to owe taxes, you should project and pay the amount due by April 15 to minimize interest and late payment penalties.

If you live outside the United States and Puerto Rico or serve in the military outside these two locations, you’re allowed an automatic two-month extension without filing for one. But you still must pay any tax due by April 15.

Paying the first installment of 2026 estimated taxes

If you make estimated tax payments, the first 2026 payment is due April 15. You can be subject to penalties if you don’t pay enough tax during the year through estimated tax payments and withholding. Generally, you’ll need to make estimated tax payments if you have taxable income without withholding, such as self-employment income, interest, dividends or capital gains from asset sales, and will likely owe $1,000 or more when you file your 2026 tax return next year.

For you to avoid penalties, your estimated payments and withholding must equal at least 90% of your tax liability for 2026 or 110% of your tax for 2025 (100% if your adjusted gross income for 2025 was $150,000 or less or, if married filing separately, $75,000 or less). Paying the appropriate amount of estimated taxes on time can help you avoid or reduce interest and penalties.

Filing a 2025 income tax return for a trust or estate

If you’re the trustee of a trust or the executor of an estate that follows a calendar tax year, you may be required to file an income tax return (Form 1041) for the trust or estate — and pay any tax due — by April 15. Filing is required when a trust or estate has gross income of $600 or more during the tax year or if any beneficiary is a nonresident alien.

For the year of death, a Form 1041 must also be filed for the deceased to report any income, as well as deductions and credits, up until the date of death. If the deceased’s assets immediately passed to the heirs, a Form 1041 generally won’t be required because the estate won’t have any post-death income.

If you’re not ready to file Form 1041 by April 15, you can file an automatic five-and-a-half-month extension (Form 7004) to September 30, 2026 (or a six-month extension to October 15, 2025, if it’s a bankruptcy estate). But any tax due still needs to be paid by April 15.

Meet your deadlines

As you can see, depending on your situation, you may have more to do by April 15 than just file your Form 1040. And this isn’t a complete list. For example, April 15 is also the deadline for individuals to file a federal gift tax return and a Report of Foreign Bank and Financial Accounts (FBAR). Contact your Smolin representative, to identify which April 15 deadlines apply to you and get help meeting them so you stay compliant, reduce risk, and potentially save on taxes.

Paying Interest? Here Are 4 Types You May Be Able to Deduct
Paying Interest? Here Are 4 Types You May Be Able to Deduct 266 266 Noelle Merwin

Personal interest expense generally can’t be deducted for federal tax purposes. There are, however, exceptions. Here are four, one of which is a new break under the One Big Beautiful Bill Act (OBBBA), which was signed into law in 2025.

1. Mortgage interest

Perhaps the most well-known interest expense deduction, home mortgage interest may be deductible if you itemize deductions rather than claiming the standard deduction. You generally can deduct interest on mortgage debt incurred to purchase, build or improve your principal residence and a second residence. Points paid related to your principal residence also may be deductible.

The OBBBA made permanent the Tax Cuts and Jobs Act’s (TCJA’s) reduction of the mortgage debt limit from $1 million to $750,000 for debt incurred after December 15, 2017, with some limited exceptions. But the OBBBA also generally made mortgage insurance premiums deductible as mortgage interest — though not until the 2026 tax year. So you can’t deduct these premiums on your 2025 return.

2. Auto loan interest

The OBBBA allows eligible individuals — whether or not they itemize — to deduct some or all of the interest paid on a loan taken out after 2024 to purchase a qualifying new car, minivan, van, SUV, pickup truck or motorcycle with a gross vehicle weight rating under 14,000 pounds. For 2025 through 2028, you can potentially deduct up to $10,000 each year. But various requirements and limits apply.

One of the most significant requirements is that the vehicle’s “final assembly” must occur in the United States. An important limit to be aware of is that the deduction is phased out starting at $100,000 of modified adjusted gross income (MAGI) or $200,000 for married couples filing jointly. The deduction is completely phased out when MAGI reaches $150,000 ($250,000 for joint filers).

3. Student loan interest

If you have student loan debt, you may be able to deduct the interest, subject to various rules and limits. You don’t have to itemize to claim the deduction, and the maximum deduction is $2,500. The interest must be for a “qualified education loan,” which means a debt incurred to pay tuition, room and board, and related expenses to attend a post-high-school educational institution, including certain vocational schools. Post-graduate programs may also qualify.

For 2025, the deduction begins to phase out for single taxpayers when MAGI exceeds $85,000 ($175,000 for joint filers). The deduction is unavailable for single taxpayers with MAGI of more than $100,000 ($205,000 for joint filers). Married taxpayers must file jointly to claim this deduction. Taxpayers who can be claimed as a dependent on another tax return aren’t eligible.

4. Investment interest

Investment interest — interest on debt used to buy assets held for investment, such as margin debt used to buy securities — may be deductible. But you can’t deduct interest you incurred to produce tax-exempt income. For example, if you borrow money to invest in municipal bonds, which are exempt from federal income tax, you can’t deduct the interest.

Perhaps more significant, your investment interest deduction is limited to your net investment income, which, for the purposes of this deduction, generally includes taxable interest, nonqualified dividends and net short-term capital gains, reduced by other investment expenses. In other words, qualified dividends and long-term capital gains aren’t included (unless you elect to treat them as nonqualified dividends or short-term capital gains subject to the higher tax rates that apply to those types of income). Any disallowed interest is carried forward. You can then deduct the disallowed interest in a later year if you have excess net investment income.
