If you make estimated tax payments, remember that the final 2025 payment is due Jan. 15, 2026. 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 2025 tax return. Paying the appropriate amount on time can help you avoid or reduce underpayment penalties and interest charges. We can help you determine how much you need to pay.
