Potential upcoming tax changes
These are only some of the tax limits and deductions that may affect your business, and additional rules may apply. But there’s more to keep in mind. With President Trump back in the White House and the Republicans controlling Congress, several tax policy changes have been proposed and could potentially be enacted in 2025. For example, Trump has proposed lowering the corporate tax rate (currently 21%) and eliminating taxes on overtime pay, tips, and Social Security benefits. These and other potential changes could have wide-ranging impacts on businesses and individuals. It’s important to stay informed. Consult with us if you have questions about your situation.
