Failure to File & Pay Penalty Calculator

The Failure-to-File Penalty and the Failure-to-Pay Penalty Calculator provide quick solutions for computing the complex penalty amount.

What Are the Failure-to-File and Failure-to-Pay Penalties?

The Failure-to-File Penalty is charged when you don’t submit your tax return by the due date (usually April 15). Meanwhile, the Failure-to-Pay Penalty is assessed when you don’t pay the taxes you owe on time. While these penalties are distinct, they can overlap if you fail to file and pay, compounding your tax bill.

Failure-to-File Penalty

How much is the penalty for failure to Pay or File?

The penalty is 5% of the unpaid taxes for each month (or part of a month) that your return is late, up to a maximum of 25%.It begins accruing the day after the tax-filing deadline.

Exceptions to failure to file penalty?

You can avoid this penalty if you file for an extension and meet the extended deadline. However, you must still pay any owed taxes by the original due date to avoid the Failure-to-Pay Penalty.

What is a Failure-to-Pay Penalty?

When you fail to pay the tax outstanding as per your return or any bill the IRS gives you after processing the tax return, you will be charged a failure to pay penalty—automatically!

How much is failure to pay penalty?

The penalty rate is 0.5% of the unpaid taxes for each month (or part of a month) after the due date, up to a maximum of 25%.

When does the failure to pay penalty start?

It accrues the day after the payment deadline, typically April 15, for tax outstanding on your tax return.For example, f you owe $10,000 and pay two months late, your Failure-to-Pay Penalty would be:$10,000 x 0.5% x 2 months = $100.

What If Both Penalties Apply?

When both penalties apply in the same month, the Failure-to-File Penalty is reduced to 4.5%, resulting in a combined penalty rate of 5% per month (4.5% for filing + 0.5% for payment).

Example: If you owe $10,000, file two months late, and haven’t paid, the combined penalty would be:
$10,000 x 5% x 2 months = $1,000.

Interest on Penalties and Unpaid Taxes

In addition to penalties, the IRS charges interest on the unpaid tax balance, starting from the original due date. The interest rate changes quarterly and is typically the federal short-term rate plus 3%.
