Whether you’re managing personal taxes or running a business, missing a filing deadline can lead to more than just stress—it can trigger costly late payment penalties. These penalties, combined with interest, can quickly escalate what you owe and complicate your financial situation. Unfortunately, many taxpayers don’t realize how fast these charges accumulate or that there are ways to minimize them.
Missing a tax deadline can be stressful, but ignoring it will only make things worse. If you owe taxes and haven’t paid yet, the IRS starts adding late payment penalties and interest immediately.
The good news? There are ways to reduce what you owe and avoid costly mistakes.

What Happens If You Pay Taxes Late?
When you miss the payment deadline, the IRS applies two types of late payment penalties:
1. Failure-to-Pay Penalty
- 0.5% per month on unpaid taxes, up to a maximum of 25%.
- Begins accruing the day after the tax deadline
2. Interest on Unpaid Taxes
- Charged daily, based on the federal short-term rate + 3%. The IRS provides more details on how interest is calculated on unpaid taxes.
- The longer you wait, the more you owe — and the more difficult it becomes to catch up.
Important Note: If you haven’t filed your tax return yet, there’s also the Failure-to-File penalty, which is much worse—5% per month, up to 25%. That’s on top of the failure-to-pay penalty.
If you’re behind, consider filing as soon as possible and exploring payment plans or penalty abatement options. The IRS is more flexible than many people realize—but only if you take action.
How to Minimize IRS Late Payment Penalties
If you missed the deadline, here’s what to do right now to limit late payment penalties and interest. Taking quick action—no matter how behind you feel—can make a big difference in how much you ultimately owe.
1. File as Soon as Possible, Even If You Can’t Pay in Full
Filing your return stops the Failure-to-File penalty, which is the largest penalty the IRS applies. This penalty grows much faster than the late payment penalty, so filing quickly is your first and most important step. Even if you’re not ready to pay in full, submitting your return reduces financial damage.

2. Pay What You Can Right Away
Even partial payments help reduce penalties and interest. Every dollar you pay now stops interest from compounding on that amount. Paying a portion signals to the IRS that you’re making a good-faith effort, which can help if you apply for a payment plan or request penalty relief later.
3. Set Up an IRS Payment Plan
If you owe more than you can afford, the IRS offers installment agreements that let you pay over time. These plans are easier to set up than many people realize and may help you avoid further penalties if you stay current. Some plans even waive setup fees for lower-income taxpayers.
You can apply for a payment plan online through the IRS’s Online Payment Agreement Application.
Final Thoughts: Take Action Now to Reduce IRS Late Payment Penalties
