IRS Failure to Pay Penalty: 2026 Costs, Rules, and Relief
The irs failure to pay penalty is a monthly fee charged when you do not pay the tax you owe by the original deadline. For the 2026 tax season, this penalty is generally 0.5% of the unpaid taxes for each month or part of a month the balance remains unpaid. This penalty caps at a maximum of 25% of your total unpaid tax, but it is often accompanied by daily compounding interest, currently set at 7% per year.
In this guide, we will break down the specific triggers for the irs failure to pay penalty, how it interacts with the late filing penalty, and the exact steps you can take to have these fees removed through 2026 relief programs. Understanding how the IRS calculates this debt is the first step toward reclaiming your financial peace of mind.
What is the IRS Failure to Pay Penalty?
The IRS expects all taxes to be paid by the filing deadline, which is typically April 15. If you have a balance due after that date, the irs failure to pay penalty (officially governed by IRC 6651(a)(2)) begins to accrue. Unlike a one-time late fee, this penalty grows every month you wait to pay.
Even if you filed an extension, the irs failure to pay penalty still applies to any tax not paid by the original April date. However, if you paid at least 90% of your actual tax liability with your extension request, you may be able to avoid this penalty entirely.
Quick Tip: The IRS charges for a “full month” even if you are only one day late into a new cycle. If you are planning a payment, try to submit it before your next monthly “anniversary” of the tax deadline.
Takeaway: The failure to pay penalty starts the day after the tax deadline and applies to whatever balance remains on your account.
How the 2026 Penalty Rates are Calculated
The IRS uses different rates for the irs failure to pay penalty depending on your communication with them. Being proactive and setting up a payment plan can significantly lower your costs.
- Standard Rate: 0.5% per month of the unpaid tax.
- Approved Payment Plan: 0.25% per month while the installment agreement is in effect (for individuals who filed on time).
- Notice of Intent to Levy: 1.0% per month, starting 10 days after the IRS issues a final notice to seize property.
Comparison: Failure to Pay vs. Failure to File
| Penalty Type | Monthly Rate | Maximum Cap |
|---|---|---|
| IRS Failure to Pay Penalty | 0.5% | 25% |
| Failure to File Penalty | 5.0% | 25% |
| Combined (Same Month) | 5.0% total | 47.5% (Total) |
Takeaway: Filing your return on time—even if you can’t pay—removes the 5% monthly filing penalty, leaving you with only the much smaller 0.5% irs failure to pay penalty.
Daily Compounding Interest in 2026
On top of the irs failure to pay penalty, the government also charges interest on the unpaid tax from the original due date. In 2026, the interest rate for individuals is 7% per year.
Unlike the penalty, interest is compounded daily. This means your balance grows a little bit every 24 hours. Furthermore, the IRS charges interest on the penalty itself if it is not paid within 21 days of the notice date. This “interest on interest” is why tax debt can feel like it is spiraling out of control if left unaddressed.

Takeaway: Interest has no maximum cap, while the penalty stops growing once it reaches 25%.
How to Remove the Penalty (Abatement)
If you have been hit with an irs failure to pay penalty, you may qualify for relief. The IRS offers two main types of “Abatement” to help taxpayers who made an honest mistake or faced a major hardship.
- First-Time Abate (FTA): If you have a clean history for the last three years (no penalties) and have filed all current returns, the IRS will often remove the penalty as a “one-time” courtesy.
- Reasonable Cause: If you were late due to circumstances beyond your control, such as a death in the family, a serious illness, or a natural disaster, you can submit an appeal with proof to have the penalty waived.
You can learn more about these strategies on our How to Avoid Penalties page or learn About Us. If you are a business owner, check the specific rules for Partnerships and S-Corps. If you need help with a notice, please visit our Contact page.
Takeaway: If the IRS removes your penalty, they will also automatically remove any interest that was charged on that penalty.
Frequently Asked Questions
Can I get a waiver if I just didn’t have the money?
Generally, a “lack of funds” is not considered a reasonable cause by the IRS. However, if you can show that paying on time would have caused you “undue hardship” (meaning you wouldn’t be able to pay for basic living expenses), you may qualify for relief.
What happens if my bank doesn’t honor my payment?
In addition to the irs failure to pay penalty, you will be hit with a “dishonored check” penalty. For payments over $1,250, this is 2% of the total; for payments under $1,250, it is $25 or the check amount, whichever is less.
Does an extension of time to file give me more time to pay?
No. An extension only prevents the 5% late filing penalty. The irs failure to pay penalty and interest still begin accruing on any unpaid tax after the original April deadline.
How do I apply for a penalty waiver in 2026?
You can call the toll-free number on your IRS notice, or you can file Form 843, “Claim for Refund and Request for Abatement”. Simply explain why you were late and provide any supporting documents, like medical records or fire reports.
