How to Respond to an IRS PCORI Penalty Letter
Article Summary
PCORI penalty letters from the IRS typically stem from lateness in filing or making payments or mistakes when filing PCORI fee reports using form 720.
Some of the reasons for getting such notices include failure to make the payment on time, underpaying the amount or calculating it wrongly by use of wrong numbers for covered lives or plan year and applicable rate.
Failure to file before the July 31st deadline attracts a five percent penalty every month up to a maximum of 25 percent of the outstanding balance.
Unpaid amounts, even if filed timely, incur further penalties and interest until they are cleared.
Wrong calculation of the applicable rate, plan year and number of covered lives attracts penalties from the IRS for underpayment.
Please review the penalty type, tax period, payment, Form 720 filing and calculation supporting information before preparing your response.
Your response will be different according to your agreement or disagreement or qualification for penalty relief.
You need to make the payment and also file a Form 720-X separately if there is any amendment that is needed.
A written response should include supporting documents such as confirmation of filing, proof of payment and covered lives calculations.
You could ask for relief for valid reasons such as illness, disaster and if you qualify for First Time Abate.
Almost all the penalties can be avoided if you perform your calculations correctly and file your form 720 within the time frame and select the proper quarter.
You always need to calculate your covered lives, use the proper rate and also file your Form 720 in the proper quarter (Q2 for PCORI).
Authorized portals are helpful in reducing your error chances because they automate your calculations and validation and also ensure proper filing of the form.
Getting a PCORI penalty letter is stressful, but ignoring it makes things worse. The IRS charges compounding interest and escalating penalties the longer you wait. This guide walks you through what the notice means, how to respond, and how to avoid repeat issues.
Why Did You Receive an IRS PCORI Penalty Letter?
A PCORI penalty notice can arrive for more than one reason. Knowing which one applies to your situation is the faster path to getting it resolved.
1)Late Filing of Form 720
The PCORI fee is reported once a year on Form 720, due by July 31 of the year following the plan year's end. Missing that deadline triggers automatic Form 720 penalties at 5% of the unpaid fee for each month or partial month the return remains unfiled, up to 25%. No extension is available for this deadline.
2)Late Payment or Underpayment of the PCORI Fee
If you filed on time but paid less than what was owed, the IRS applies a separate 0.5% monthly penalty on the unpaid amount, capped at 25%. Interest compounds daily on top of that. Both penalties can run simultaneously, though the failure-to-file charge is reduced by the failure-to-pay amount during any overlapping month.
3)Errors in Previously Filed Returns
Reporting the wrong applicable dollar amount, using the incorrect plan year, or miscounting covered lives can produce a shortfall. The rate for plan years ending on or after October 1, 2025 (and before October 1, 2026) is $3.84 per covered life, and $3.47 for years ending between October 1, 2024 and September 30, 2025. Applying the wrong rate is a common cause of underpayment.
What to Do Immediately After Receiving the Notice?
Receiving an IRS notice can feel alarming, but responding within the first few days is what keeps the situation manageable. These steps help you assess what you are actually dealing with before deciding how to act.
1)Review the Notice Carefully
Start by reading every line of the notice. You need to know the penalty type, the tax period it covers, the dollar amount assessed, and when a response is due. Some notices involve a Form 720 compliance issue, others flag a PCORI fee filing error, and some cite both. The IRS is not always right, so hold off on paying until you have read it fully.
2)Gather Supporting Documentation
Get your records together before you do anything else. That means your Form 720 filing confirmation, proof of payment, covered lives count data, and any earlier IRS correspondence. If the Form 5500 method or snapshot method was used for your covered lives count, find those worksheets too. You will need hard records either way, whether you are disputing the charge or confirming it.
3)Determine Whether the Penalty Is Correct
Run your own numbers and compare them to what the IRS is claiming. Check the plan year-end date, the dollar rate applied, and the covered lives figure from your original calculation. IRS notices carry errors more often than most people expect, especially when a return was filed but did not get recorded on the IRS side.
How to Respond to an IRS PCORI Penalty Letter?
The right response depends on whether the penalty is accurate. There are three distinct paths, and taking the right one matters for both your finances and compliance record.
1)If You Agree With the IRS Assessment
Pay the full amount by the deadline shown in the notice. If you also owe for a prior year, file Form 720-X to amend that return separately. Do not reduce a current year PCORI fee filing to offset a prior overpayment. Each year requires its own correction.
2)If You Believe the Penalty Is Incorrect
Submit a written response to the address on the notice. Your written response needs backup. Attach proof of timely filing, payment records, or the covered lives figures from your original calculation.
If the IRS used the wrong rate or treated the plan type incorrectly, cite the Patient-Centered Outcomes Research Trust Fund fee guidelines directly in your response. Send copies, not originals, and keep a full set for yourself.
3)Request Penalty Relief for Reasonable Cause
If the penalty is accurate but resulted from circumstances outside your control, you may qualify for IRS penalty relief. Reasonable causes include serious illness, natural disaster, or reliance on incorrect professional advice.
Request penalty relief for reasonable cause in writing with supporting documents. A clean three-year compliance history may also qualify you for First Time Abate, which the IRS can often process over the phone.
Prevent Future PCORI Penalties With Accurate Filing
Prevention costs less than correction. A few consistent habits significantly reduce the chance of receiving another PCORI penalty notice.
1)Verify Covered Lives and Fee Calculations
More PCORI underpayments come from math errors than from missed deadlines. Before you file, verify covered lives and fee calculations, confirm the plan year end date, and use only the applicable dollar amount tied to that exact period. Getting these three things right removes the most common source of penalty exposure.
2)File Form 720 for the Correct Quarter
A common mistake is filing Form 720 for the wrong quarter. PCORI fees are always reported for the quarter ending June 30, regardless of when the plan year ended. Filing for Q4 instead of Q2 causes the IRS to misapply the payment, which typically generates a late filing notice. Review the About IRS Form 720 instructions each year before submitting.
3)Understand the Consequences Before They Happen
Most late filers underestimate how fast charges add up. The consequences of not filing Form 720 on time include a 5% monthly failure-to-file penalty, a separate failure-to-pay charge, and daily compounding interest. What starts as a few dollars per covered life can become a significant liability within a quarter.
