Filed a tax extension? Finish filing by October 15.

The due date to file 2023 tax returns or to file an extension is April 15, 2024. Taxpayers living in Maine or Massachusetts have until April 17, 2024, due to the Patriot’s Day and Emancipation Day holidays.

No. An extension doesn't delay your payment deadline if you owe money to the IRS. An extension only allows you more time to finish filing your tax return. If you haven't paid your estimated tax balance due by April 15, you should do so as soon as possible to minimize penalties and interest.

No. If you are unable to pay your taxes in full, you can set up an Installment Agreement payment plan with the IRS. This allows you to take up to 72 months (about 6 years) to pay your taxes in full. Our expert Tax Pros can help you set up a payment plan with the IRS.

While penalties and interest may depend on your unique situation, generally the IRS charges the following:

• 0.5%, or half a percent, interest for every month
• Maximum penalty for late payment is 25% of the total amount owed
• Don't forget: The IRS compounds interest daily and penalty assessments monthly

The IRS combines the late-filing and late-payment penalties for each month you are subject to both. The maximum penalties per month are 4.5% for late filing plus 0.5% for late payments for a total of 5% per month. Generally, the maximum penalty is 25%.

The IRS will assess penalties and interest on the outstanding taxes until they are paid in full. Consider an IRS Installment Agreement for payment if you owe and can't pay all of your taxes at once.
