Failure-to-File vs Failure-to-Pay: Which Penalty Is Worse?
Failure-to-File vs Failure-to-Pay: Which Penalty Is Worse?
If you miss the April 15 tax deadline, the IRS can hit you with two separate penalties: the failure-to-file penalty and the failure-to-pay penalty. They sound similar but are dramatically different in cost. Understanding the distinction is critical because it determines the single most important action you should take when you cannot meet your tax obligations: file your return on time, even if you cannot pay.

The Two Penalties at a Glance
| Failure-to-File | Failure-to-Pay | |
|---|---|---|
| Trigger | Not filing your return by the deadline | Not paying your tax by the deadline |
| Rate | ~5% per month of unpaid tax | ~0.5% per month of unpaid tax |
| Maximum | ~25% of unpaid tax | ~25% of unpaid tax |
| Minimum (after 60 days) | ~$510 or 100% of tax owed (whichever is less) | None |
| Starts accruing | Day after the filing deadline | Day after the payment deadline |
| Stopped by | Filing your return | Paying your balance in full |
The failure-to-file penalty is ten times the failure-to-pay penalty. This ratio makes the answer to “which is worse?” clear before we even look at the details.
Failure-to-File Penalty: The Expensive One
How It Works
If you do not file your federal tax return by the deadline (April 15 for most individuals, or October 15 if you filed an extension), the IRS charges a penalty of ~5% of your unpaid tax for each month or partial month your return is late.
Key details:
- The penalty is based on the unpaid tax amount, not your total tax liability. If you owe ~$10,000 and have already paid ~$8,000 through withholding, the penalty applies to the ~$2,000 remaining balance.
- A partial month counts as a full month. If your return is one day late, you owe one month’s penalty.
- The maximum penalty is ~25% of your unpaid tax, reached after 5 months of non-filing.
- If your return is more than 60 days late, the minimum penalty is the lesser of ~$510 or 100% of your unpaid tax. This minimum applies even if your balance is small.
Example: ~$5,000 Unpaid Balance
| Months Late | Monthly Penalty (~5%) | Cumulative Penalty | Total Owed |
|---|---|---|---|
| 1 | ~$250 | ~$250 | ~$5,250 |
| 2 | ~$250 | ~$500 | ~$5,500 |
| 3 | ~$250 | ~$750 | ~$5,750 |
| 4 | ~$250 | ~$1,000 | ~$6,000 |
| 5 | ~$250 | ~$1,250 | ~$6,250 |
| 6+ | ~$0 (max reached) | ~$1,250 | ~$6,250 |
In just five months, the failure-to-file penalty adds ~$1,250 to a ~$5,000 balance — that is a ~25% increase.
The 60-Day Minimum Penalty
This provision catches people with small balances who assume it does not matter if they file late. If your return is more than 60 days overdue, the penalty is at least ~$510, even if your unpaid balance is only ~$300. In that case, the penalty would be ~$300 (100% of the tax owed, since that is less than ~$510).
Failure-to-Pay Penalty: The Cheaper One
How It Works
If you file your return on time but do not pay your tax balance by the deadline, the IRS charges ~0.5% of your unpaid tax for each month or partial month the balance remains unpaid.
Key details:
- The rate is ~0.5% per month — one-tenth of the failure-to-file rate.
- The maximum is ~25% of your unpaid tax, but reaching this maximum takes 50 months (over 4 years).
- The rate increases to ~1% per month after the IRS issues a final notice of intent to levy (typically after multiple collection notices).
- The rate decreases to ~0.25% per month if you have an approved installment agreement with the IRS.
- There is no minimum penalty amount.
Example: ~$5,000 Unpaid Balance
| Months Late | Monthly Penalty (~0.5%) | Cumulative Penalty | Total Owed |
|---|---|---|---|
| 1 | ~$25 | ~$25 | ~$5,025 |
| 3 | ~$25 | ~$75 | ~$5,075 |
| 6 | ~$25 | ~$150 | ~$5,150 |
| 12 | ~$25 | ~$300 | ~$5,300 |
| 24 | ~$25 | ~$600 | ~$5,600 |
After a full year, the failure-to-pay penalty on a ~$5,000 balance is only ~$300 — compared to ~$1,250 for failure-to-file in just five months.
When Both Penalties Run Simultaneously
If you both fail to file and fail to pay, both penalties apply. However, the IRS does not simply add them together — the failure-to-file penalty is reduced by the failure-to-pay penalty for the same period.
The Combined Calculation
For each month you are both late to file and late to pay:
- Failure-to-file penalty: ~5%
- Failure-to-pay penalty: ~0.5%
- But the FTF penalty is reduced by the FTP amount
- Net FTF penalty: ~5% - ~0.5% = ~4.5%
- Combined monthly cost: ~4.5% (FTF) + ~0.5% (FTP) = ~5% total
This means the combined penalty is the same as the failure-to-file penalty alone for the first five months. After month 5, the FTF penalty maxes out at ~25%, but the FTP penalty continues at ~0.5% per month.
Example: ~$5,000 Balance, Neither Filed nor Paid
| Months | FTF Penalty | FTP Penalty | Combined Cumulative | Balance |
|---|---|---|---|---|
| 1 | ~$225 | ~$25 | ~$250 | ~$5,250 |
| 2 | ~$225 | ~$25 | ~$500 | ~$5,500 |
| 3 | ~$225 | ~$25 | ~$750 | ~$5,750 |
| 4 | ~$225 | ~$25 | ~$1,000 | ~$6,000 |
| 5 | ~$225 | ~$25 | ~$1,250 | ~$6,250 |
| 6 | ~$0 (FTF maxed) | ~$25 | ~$1,275 | ~$6,275 |
| 12 | ~$0 | ~$25 | ~$1,425 | ~$6,425 |
| 24 | ~$0 | ~$25 | ~$1,725 | ~$6,725 |
| 50 | ~$0 | ~$25 (FTP maxes) | ~$2,500 | ~$7,500 |
Maximum combined penalty: ~25% (FTF) + ~25% (FTP) = ~50% of the original unpaid tax. A ~$5,000 balance could become ~$7,500 in penalties alone, not counting interest.
Interest on Top of Penalties
Both penalties are separate from interest, which the IRS charges on unpaid tax and on unpaid penalties. The interest rate is the federal short-term rate plus ~3%, compounded daily. As of early 2026, the IRS interest rate for underpayments is ~7% annually.
Adding interest to the scenario above:
| Timeframe | Penalties | Interest (est.) | Total Added |
|---|---|---|---|
| 6 months (filed late + unpaid) | ~$1,275 | ~$200 | ~$1,475 |
| 12 months (filed late + unpaid) | ~$1,425 | ~$430 | ~$1,855 |
| 24 months (filed late + unpaid) | ~$1,725 | ~$950 | ~$2,675 |
Why You Should Always File on Time
The math makes the strategy clear. Compare these two scenarios for a ~$5,000 unpaid balance over 6 months:
| Scenario | Penalties | Interest | Total Extra Cost |
|---|---|---|---|
| Filed on time, did not pay | ~$150 (FTP only) | ~$175 | ~$325 |
| Did not file, did not pay | ~$1,275 (FTF + FTP) | ~$200 | ~$1,475 |
Filing on time saves approximately ~$1,150 on a ~$5,000 balance over just six months. The savings scale proportionally with larger balances.
If you cannot complete your return by April 15, file a tax extension — it is free and takes minutes. This moves your filing deadline to October 15 and eliminates the failure-to-file penalty entirely.
First-Time Penalty Abatement
The IRS offers a one-time waiver for both the failure-to-file and failure-to-pay penalties under its First-Time Penalty Abatement (FTA) policy.
Eligibility
- No penalties (other than estimated tax penalties) in the 3 prior tax years
- All required returns filed (or extensions filed)
- All tax paid or arranged to be paid (installment agreement counts)
How to Request
- By phone: Call 1-800-829-1040 and request FTA
- In writing: Respond to the penalty notice with a letter citing your clean compliance history
- After paying: You can request a refund of penalties already paid if you qualify
What FTA Removes
FTA waives the penalties but not the interest. However, since interest accrues on penalty balances, removing the penalty also reduces the total interest owed.

Reasonable Cause: Another Path to Penalty Relief
If you do not qualify for First-Time Penalty Abatement, the IRS may still waive penalties if you can demonstrate “reasonable cause” for the late filing or late payment.
Examples of Reasonable Cause
- Serious illness or medical emergency
- Death of an immediate family member
- Natural disaster affecting your ability to file
- Inability to obtain necessary records (fire, theft)
- Reliance on incorrect advice from a tax professional
- IRS error or delay
How to Request
Attach a written statement to your return or respond to the penalty notice explaining the circumstances. Include documentation (medical records, police reports, insurance claims, etc.) to support your claim.
What Is NOT Reasonable Cause
- “I forgot”
- “I was too busy”
- “I did not know I owed taxes”
- “My tax preparer was behind schedule” (unless you exercised ordinary business care in selecting the preparer)
- Financial hardship alone (for FTF penalty — though it may be relevant for FTP)
Special Cases
Return Shows a Refund
If your return results in a refund (meaning you overpaid your taxes through withholding or estimated payments), neither penalty applies. The failure-to-file and failure-to-pay penalties are calculated on unpaid tax only. A late-filed return claiming a refund has no penalty, though the IRS will not pay you interest on the refund for the period between the due date and the filing date.
Important: You must file within 3 years of the original deadline to claim a refund. After 3 years, the refund is forfeited permanently.
Extensions
Filing a tax extension moves your filing deadline to October 15. If you file by October 15, no failure-to-file penalty applies. However, the failure-to-pay penalty still runs from April 15 if you have not paid your balance.
Estimated Tax Penalty
The estimated tax penalty (also called the underpayment penalty) is a separate penalty that applies if you did not make sufficient estimated payments or have enough withholding throughout the year. It is calculated differently from both the FTF and FTP penalties and is assessed on Form 2210. This penalty cannot be waived through First-Time Penalty Abatement.

Frequently Asked Questions
Can I negotiate the penalty rate with the IRS?
No. The penalty rates are set by law (Internal Revenue Code Sections 6651(a)(1) and 6651(a)(2)). The IRS cannot reduce the rate. However, it can waive the penalty entirely through FTA, reasonable cause, or statutory exception.
Do penalties apply to state taxes too?
Each state sets its own penalty rates and rules. Many states mirror the federal structure but with different rates. Check your state tax agency’s website for specific penalty information.
What if I file late but do not owe anything?
No penalty. Both the failure-to-file and failure-to-pay penalties are based on unpaid tax. If your balance is zero (or you are owed a refund), there is no penalty for late filing.
Can penalties be discharged in bankruptcy?
Tax penalties that are more than 3 years old may be dischargeable in a Chapter 7 bankruptcy, but the rules are complex. Consult a bankruptcy attorney for advice specific to your situation.
How are penalties reported on my IRS account?
Penalties appear as separate line items on your IRS account transcript. You can view your balance, penalty charges, and interest by logging into your IRS Online Account or requesting a transcript.
The Bottom Line
The failure-to-file penalty at ~5% per month is ten times more expensive than the failure-to-pay penalty at ~0.5% per month. This single fact drives every piece of advice in this article:
- Always file on time, even if you cannot pay a single dollar
- File an extension if you need more time to prepare your return
- Pay what you can to reduce the balance subject to the failure-to-pay penalty
- Request penalty abatement if you have a clean 3-year compliance history
- Set up a payment plan to reduce the ongoing FTP penalty rate to ~0.25% per month
The worst-case scenario — not filing and not paying — combines both penalties for a maximum of ~50% of your unpaid tax, plus interest. That is entirely avoidable by spending five minutes filing your return or extension by the deadline.
