IRS Penalties: A Complete Guide to Types, Rates, and How to Get Relief
Most people know the IRS can penalize you for filing late or not paying what you owe—but did you know there are at least six distinct types of IRS penalties, each with its own rate, trigger, and relief pathway? The failure-to-file penalty alone can balloon to 25% of your unpaid taxes before you even realize it's accumulating.
Understanding how IRS penalties work—and more importantly, how to fight them—can save you hundreds or even thousands of dollars. Here's everything you need to know.
What Are IRS Penalties?
IRS penalties are charges added to your tax bill when you fail to comply with tax laws. They're separate from interest, which accrues independently on any unpaid balance. Both compound over time, meaning the longer you wait to resolve a tax issue, the more expensive it becomes.
The IRS assesses penalties automatically in most cases, using computerized systems that detect late filings, missed payments, and discrepancies. You don't get a warning before a penalty is assessed—it simply appears on your next notice.
The 6 Main Types of IRS Penalties
1. Failure to File Penalty
When it applies: Your tax return wasn't filed by the due date (including any extensions you were granted).
Rate: 5% of the unpaid taxes for each month or partial month your return is late, up to a maximum of 25%.
Minimum penalty: If your return is more than 60 days late, the minimum penalty is the lesser of $525 (for returns required to be filed in 2026) or 100% of the unpaid tax. This means even if you owe $200, a return that's over 60 days late will cost you the full $200 in penalties.
Key detail: If you're owed a refund, there's no failure-to-file penalty—but you still lose your refund if you wait more than three years to file.
2. Failure to Pay Penalty
When it applies: You filed your return on time but didn't pay the full amount owed by the due date.
Rate: 0.5% of your unpaid taxes per month or partial month, up to a maximum of 25%.
Reduced rate: If you file your return on time and set up an approved IRS payment plan, the rate drops to 0.25% per month while the plan is in effect.
Combined cap: When both failure-to-file and failure-to-pay penalties apply in the same month, the failure-to-file penalty is reduced by the failure-to-pay amount. The combined maximum penalty is 47.5%—22.5% for late filing plus 25% for late payment.
3. Failure to Deposit Penalty
When it applies: Employers who miss deadlines for depositing employment taxes (federal income tax withholding, Social Security, Medicare, and FUTA taxes).
Rates are tiered based on how late the deposit is:
| Days Late | Penalty Rate |
|---|---|
| 1–5 days | 2% |
| 6–15 days | 5% |
| More than 15 days | 10% |
| 10+ days after first IRS notice | 15% |
Note: These rates replace each other—they don't stack. If you're 20 days late, you owe 10%, not 2% + 5% + 10%.
Employers must deposit employment taxes on either a monthly or semi-weekly schedule, depending on their total tax liability from the prior year. Missing these deposits is one of the most common payroll mistakes small businesses make.
4. Accuracy-Related Penalty
When it applies: You filed your return but it contained errors that resulted in underpaying taxes. This includes:
- Negligence or disregarding IRS rules
- Substantial understatement of income tax (understating your tax liability by more than 10% of the correct tax or $5,000, whichever is greater)
- Substantial valuation misstatement
- Unreported foreign financial assets
Rate: 20% of the underpayment attributable to the inaccuracy. If the underpayment involves fraud, the rate jumps to 75%.
How to avoid it: Maintain thorough records for every deduction you claim, and don't guess at numbers. When in doubt, consult a tax professional before filing.
5. Underpayment of Estimated Tax Penalty
When it applies: If you're self-employed, a freelancer, or have income not subject to withholding, you're generally required to pay estimated taxes quarterly. If those quarterly payments are too small—or not paid at all—the IRS assesses an underpayment penalty.
Who's affected: Individuals who expect to owe at least $1,000 in taxes after subtracting withholding and credits. Corporations face a similar requirement if they expect to owe $500 or more.
Safe harbor rules: You can avoid this penalty if you pay at least:
- 90% of the tax shown on your current year's return, or
- 100% of the tax shown on your prior year's return (110% if your prior-year adjusted gross income exceeded $150,000)
Rate: The IRS calculates this penalty using the federal short-term rate plus 3 percentage points, applied to the underpayment for the period it was owed.
6. Information Return Penalty
When it applies: Businesses that file information returns (like 1099-NEC, 1099-MISC, W-2, or 1095-C forms) late, incorrectly, or not at all.
Rates for 2026 (per form):
| Timing | Penalty |
|---|---|
| Filed within 30 days of deadline | $60 per form |
| Filed between 31 days late and August 1 | $120 per form |
| Filed after August 1 or not filed | $310 per form |
| Intentional disregard | $630 per form or 10% of unreported amount |
Annual caps apply per business, but the caps are eliminated entirely for intentional disregard.
IRS Interest: The Hidden Cost
Beyond penalties, the IRS charges interest on any unpaid balance—including on penalties themselves. The current interest rate on underpayments is the federal short-term rate plus 3 percentage points, adjusted quarterly. Interest compounds daily.
This means a $5,000 tax debt can grow significantly over months or years. Penalties and interest stop accruing only once the full balance is paid.
How to Avoid IRS Penalties
The best strategy is prevention. Here's what actually works:
File on time, even if you can't pay. The failure-to-file penalty (5%/month) is ten times larger than the failure-to-pay penalty (0.5%/month). If you can't afford your tax bill, file your return anyway and pay what you can. The rest can be addressed through a payment plan.
Request a filing extension when needed. Form 4868 gives individuals an automatic six-month extension to file—but not to pay. You still need to estimate and pay what you owe by the original deadline to avoid failure-to-pay penalties.
Set up quarterly estimated payments. Use IRS Form 1040-ES and calculate your estimated tax early. If your income fluctuates, the annualized income installment method can help you avoid overpaying in slow quarters.
Verify all information returns before filing. Double-check contractor names, SSNs, and payment amounts before submitting 1099s. Errors are expensive at scale.
Keep meticulous records. For accuracy-related penalties, documentation is your defense. Every deduction should have supporting receipts, invoices, or records.
How to Get IRS Penalties Removed or Reduced
First-Time Abatement (FTA)
This is the most powerful and underused penalty relief option available. Starting in 2026, the IRS now automatically applies First-Time Abatement to qualifying taxpayers—you no longer need to ask for it.
To qualify for FTA, you must:
- Have filed all required returns (or have a valid extension)
- Have no prior penalties in the three tax years before the year being penalized (or any prior penalty was removed for an acceptable reason other than FTA)
- Have paid, or arranged to pay, any tax currently due
FTA applies to failure-to-file, failure-to-pay, and failure-to-deposit penalties. If you don't receive automatic relief—for example, on an older penalty—you can request it by calling the IRS at the number on your notice or by submitting Form 843.
Reasonable Cause Relief
If FTA doesn't apply, you may still qualify for penalty relief by demonstrating "reasonable cause"—meaning you exercised ordinary business care and prudence but still couldn't comply.
Acceptable reasons typically include:
- Serious illness, hospitalization, or death of an immediate family member
- Natural disaster or fire that destroyed your records
- IRS error or incorrect written advice from the IRS
- Unavoidable absence
Simply forgetting to file or not having enough money to pay generally doesn't qualify—though financial hardship combined with extraordinary circumstances sometimes does.
How to request: Call the IRS or send a written statement explaining the circumstances to the IRS office that sent the penalty notice. Attach supporting documentation (medical records, insurance claims, etc.).
Penalty Abatement Through Form 843
For penalties that aren't resolved by phone, Form 843 (Claim for Refund and Request for Abatement) is the formal written route. File it within three years of when the return was due or two years of when you paid the penalty, whichever is later.
Installment Agreements and Offers in Compromise
If you can't pay the full balance, an IRS installment agreement reduces the failure-to-pay rate from 0.5% to 0.25% per month. An Offer in Compromise (OIC) may allow you to settle the entire debt for less than you owe, though approval requires demonstrating genuine inability to pay.
What to Do When You Get an IRS Penalty Notice
-
Don't ignore it. Ignoring a notice escalates the situation—interest keeps accruing, and the IRS may pursue collection actions including liens and levies.
-
Verify the penalty is correct. IRS notices contain errors. Compare the notice against your records and confirm the dates, amounts, and penalty type are accurate.
-
Respond within the timeframe stated. Most notices give you 60 days to respond before further action is taken.
-
Request your IRS transcript. An account transcript shows every transaction the IRS has on file for you, including when returns were processed and when payments were received. Order one for free at IRS.gov.
-
Consider professional help. For large penalties or complex situations, a CPA, enrolled agent, or tax attorney can often negotiate better outcomes than individuals dealing with the IRS directly.
Common Myths About IRS Penalties
"If I'm getting a refund, I can't get penalized." Mostly true for failure-to-file, but not for all penalty types. Estimated tax underpayment penalties can still apply even if you receive a refund at year-end.
"The IRS will work with me if I'm honest." Honesty helps, but it doesn't automatically waive penalties. You still need to formally request relief through the appropriate channels.
"Penalties are negotiable." They're not arbitrarily negotiable, but they are disputable through legitimate relief programs. The IRS has clear criteria for what qualifies—work within those criteria.
"Filing an extension means I have more time to pay." No—a filing extension gives you more time to file the paperwork, not more time to pay. Taxes are still due on the original deadline.
