IRS Penalties
Failure to File Penalty vs Failure to Pay: What's the Difference? (2026)
The short answer: in the failure to file penalty vs failure to pay comparison, the failure-to-file penalty is much bigger — 5% of the unpaid tax per month, up to 25%. The failure-to-pay penalty is just 0.5% per month, also capped at 25%. That's why you should always file on time, even if you can't pay.
⏱ Why timing matters: even one day into a new month counts as a full month for both penalties. If your return is more than 60 days late, a minimum failure-to-file penalty kicks in. Filing — or at least requesting an extension — before the deadline can save you a full 5% month right away.
Two different penalties people mix up
These are two separate things, and the names sound almost identical, so it's easy to confuse them:
- Failure-to-file penalty — charged when you don't file your return by the due date (or extended due date).
- Failure-to-pay penalty — charged when you don't pay the tax you owe by the due date.
You can owe one, the other, or both. Filing and paying are two separate obligations in the eyes of the IRS — and missing each one carries its own price tag.
How the failure-to-file penalty works
The failure-to-file penalty is the expensive one. It runs at 5% of the unpaid tax for each month or part of a month your return is late, and it tops out at 25% of the unpaid tax. So after five months of not filing, you've hit the maximum — a full quarter added to your bill (the IRS lays this out on its failure-to-file penalty page).
There's also a floor. If you file more than 60 days late, the minimum penalty is the lesser of a set dollar amount (the IRS adjusts it each year) or 100% of the tax you owe. In other words, even a small balance can trigger a painful minimum charge once you cross that 60-day mark.
How the failure-to-pay penalty works
The failure-to-pay penalty is far gentler: 0.5% of the unpaid tax per month or part of a month, also capped at 25%. Because it's so much smaller, paying late hurts a lot less than filing late (see the IRS failure-to-pay penalty page).
Two things bring it down further:
- Once you set up an approved installment agreement, the rate drops from 0.5% to 0.25% per month for individuals.
- The penalty stops growing once it reaches the 25% ceiling — though interest keeps running on the balance until it's fully paid.
Failure to file penalty vs failure to pay: a worked example
Say you owe $10,000 and you're five months late. Here's how the two penalties compare side by side:
- You filed on time but couldn't pay: only the failure-to-pay penalty applies — 0.5% × 5 months = 2.5% = $250 in penalties (plus interest).
- You didn't file and didn't pay: both apply. In months both run, the failure-to-file penalty is reduced to 4.5%, so the combined rate is 5% per month. Over five months that's 22.5% file + 2.5% pay = $2,500 in penalties (plus interest).
Same $10,000 debt. The only difference is whether you filed — and that one choice changed the penalty by $2,250. This is the whole point: filing on time, even with no payment, is the cheapest move you can make.
What happens when both penalties apply
If you file late and pay late, both clocks run at once. The IRS doesn't simply stack 5% + 0.5%. Instead, in any month both penalties apply, the failure-to-file penalty is trimmed to 4.5% so the combined rate stays at 5% per month. Each penalty still has its own 25% cap, so the most you can owe is 25% for filing late plus 25% for paying late — and interest on top of both.

How to reduce or remove these penalties
- File everything first — even if it's late. The fastest way to stop the 5% failure-to-file penalty from growing is to actually file. Unfiled years keep the meter running.
- Pay what you can now. Penalties and interest are calculated on the unpaid balance, so any payment shrinks the base they're charged on.
- Set up a payment plan. An installment agreement cuts the failure-to-pay penalty in half (to 0.25%/month) and stops collection from escalating. If you got a first bill you can't cover, see what to do when you get a CP14 and can't pay.
- Ask for first-time penalty abatement. If you have a clean compliance history for the prior three years, the IRS may remove both penalties under its first-time penalty relief rules.
- Claim reasonable cause if it fits. Serious illness, a death in the family, a natural disaster, or records destroyed beyond your control can all support a request to waive penalties — with documentation.
Failure to file vs failure to pay, answered
Which is worse, failure to file or failure to pay?
Failure to file is far worse. The failure-to-file penalty is 5% of the unpaid tax per month, while the failure-to-pay penalty is only 0.5% per month — ten times smaller. That's why the IRS itself tells people to file on time even if they can't pay the full amount.
Can I get hit with both penalties at the same time?
Yes. If you file late and pay late, both penalties apply. But in any month both run, the failure-to-file penalty is reduced to 4.5% so the combined rate is 5% per month, not 5.5%. Each penalty caps at 25% of the unpaid tax, and interest accrues on top of both.
How much is the failure-to-file penalty if I'm only a little late?
Even one day into a new month counts as a full month at 5%. And if your return is more than 60 days late, a minimum penalty applies — the lesser of a set dollar amount (adjusted each year) or 100% of the tax you owe. Filing even a few days early can save a full 5% month.
Does the failure-to-pay penalty ever go down?
Yes. Once you set up an approved IRS installment agreement, the failure-to-pay penalty drops from 0.5% to 0.25% per month for individuals. The penalty also stops growing once it reaches its 25% maximum, though interest keeps running until the balance is paid.
Can these penalties be removed?
Often, yes. First-time penalty abatement can wipe out both penalties if you have a clean compliance history. Reasonable-cause relief may apply for serious illness, a natural disaster, or other events beyond your control. You usually have to file all required returns first, then request relief.
