Potential upcoming tax changes
These are just a few of the tax limits and deductions that might affect your business in 2025. But there’s more to watch out for. With President Trump back in office and Republicans controlling Congress, several proposed tax changes could be on the horizon.
For example, Trump has suggested lowering the corporate tax rate (currently at 21%) and eliminating taxes on overtime pay, tips, and Social Security benefits. These and other potential changes could have significant impacts on both businesses and individuals.
It’s important to stay informed and reach out to your Smolin advisor to find out how these changes might affect you.
