Andrew LathamSummary:
Penalty abatement is the IRS’s primary method for reducing tax debt costs, available for first-time mistakes or with reasonable cause. Interest abatement is much rarer, typically limited to IRS errors or delays. Most taxpayers qualify more easily for penalty relief than interest forgiveness.
When tax debt piles up, the balance grows not only from unpaid taxes but also from penalties and interest. Knowing whether you should seek penalty abatement or interest abatement can save you thousands. Let’s compare them side by side.

Comparison: Penalty Abatement vs Interest Abatement
| Feature | Penalty Abatement | Interest Abatement |
|---|---|---|
| What it does | Removes or reduces IRS penalties (failure-to-file, late payment, etc.) | Removes interest charged on unpaid taxes or penalties |
| Common programs | First-Time Penalty Abatement (FTA), Reasonable Cause Relief | Rare; only when IRS error or unreasonable delay caused the interest |
| Eligibility | Good compliance history or reasonable cause (illness, disaster, etc.) | IRS made a mistake, delayed processing, or caused the accrual |
| Availability | Relatively common; millions of taxpayers receive penalty relief each year | Very rare; granted in limited circumstances |
| Effect on debt | Can significantly reduce the total owed | Usually minimal unless IRS error caused years of extra interest |
| Process | Request via IRS form, letter, or phone call | Request in writing citing IRS error or delay |
| Best for | Taxpayers facing heavy penalties for late filing/payment | Rare cases where IRS action—not taxpayer fault—caused interest |
When penalty abatement makes more sense
- You filed or paid late but have a clean compliance history.
- You missed deadlines due to reasonable cause (serious illness, natural disaster, reliance on bad professional advice).
- Your balance is mostly made up of penalties rather than the original tax owed.

When interest abatement applies
- The IRS caused unreasonable delays in processing your return or payment.
- An IRS error directly created the interest balance.
- You qualify under specific statutory exceptions (rare).
Decision guide: which to pursue?
- Most taxpayers: Penalty abatement is the realistic option.
- Only IRS-caused issues: Consider interest abatement.
- If unsure: Request both—penalties are often granted, interest rarely.
Real-life scenarios
- Penalty abatement: A first-time filer missed the deadline due to hospitalization. The IRS granted FTA relief, removing $2,000 in penalties.
- Interest abatement: IRS misapplied payments for two years, causing excess interest. After appeal, the IRS abated the interest.
- Combined relief: A taxpayer received penalty abatement for late filing and partial interest abatement after proving IRS processing delays.
Key takeaways
- Penalty abatement is widely available through First-Time Abatement or reasonable cause.
- Interest abatement is rare and requires proof of IRS error or delay.
- Both can reduce your balance, but penalties are easier to remove than interest.
- Always request relief—you may qualify even if you assume you don’t.

Frequently Asked Questions
Is penalty abatement automatic?
No. You must request it, but the IRS often grants First-Time Abatement automatically if you ask.
How do I request penalty abatement?
You can call the IRS, write a letter, or submit a request through certain IRS forms. Be prepared to explain your circumstances.
Can interest ever be removed?
Yes, but only if the IRS caused the problem (e.g., delays, misapplied payments). Otherwise, interest accrues until the tax is paid.
Which saves more money: penalty or interest abatement?
For most taxpayers, penalty abatement saves more because penalties often make up a large portion of the balance.
Can I request both penalty and interest abatement?
Yes, but expect penalties to be more likely granted. It doesn’t hurt to request both if you qualify.
