PCORI Fee Penalty for Late Payment of Tax: What Form 720 Filers Need to Know
Missing the PCORI fee deadline is not just an administrative oversight. If your business or health plan must complete IRS Form 720 PCORI filing, the IRS can treat the unpaid amount as a late federal excise tax. That can mean a Penalty for Late Payment of Tax, a separate late filing charge and daily interest until the balance is paid.
For 2026, this matters most to employers, plan sponsors and insurers responsible for self-insured health plans or specified health insurance policies. The PCORI fee is reported on IRS Form 720, even though it is generally paid once per year rather than every quarter. If you missed the July 31 deadline or discovered a prior-year mistake, the right next step is to file, pay and document your reasonable cause as soon as possible.
Quick answer: late PCORI payment on Form 720
Late PCORI payments can trigger three IRS charges: a failure-to-file penalty if the second quarter Form 720 was not filed, a failure-to-pay penalty if the PCORI fee was not paid on time and interest on the unpaid balance. The Penalty for Late Payment of Tax generally accrues at 0.5% of the unpaid tax per month or part of a month, up to 25%, while the failure-to-file penalty is usually steeper.
| Late issue | Common IRS treatment | Practical impact |
|---|---|---|
| Form 720 not filed | Failure-to-file penalty under IRC Section 6651 | Generally 5% per month or part month of unpaid tax, capped at 25% |
| PCORI fee not paid | Failure-to-pay penalty under IRC Section 6651 | Generally 0.5% per month or part month of unpaid tax, capped at 25% |
| Balance remains unpaid | Interest under IRC Section 6601 | Compounds daily based on IRS quarterly rates |
| Reasonable cause exists | Penalty abatement may be requested | IRS may remove penalties if facts support reasonable cause and no willful neglect |
What Is PCORI, Who Pays It and Is PCORI Federally Funded?
PCORI stands for the Patient-Centered Outcomes Research Institute. If you are searching what is PCORI, the short answer is that PCORI supports research comparing medical treatments, outcomes and care delivery methods so patients and clinicians can make better-informed health decisions.
Is PCORI federally funded? PCORI is an independent nonprofit, nongovernmental organization created by federal law. Its work is funded in part through the Patient-Centered Outcomes Research Trust Fund, which receives PCORI fees collected from certain health insurance policies and self-insured health plans, along with other federal funding sources.
The PCORI fee is generally paid by:
- Issuers of specified health insurance policies
- Plan sponsors of applicable self-insured health plans
- Employers that sponsor certain self-insured arrangements, including some HRAs
Employees do not file the PCORI fee themselves. If a plan is fully insured, the insurer is usually responsible for the fee. If the employer sponsors a self-insured plan, the employer or plan sponsor is usually responsible for the PCORI filing.
PCORI Fee 2026: rates, deadline and who should review now
For the PCORI fee 2026 filing season, the key date was July 31, 2026 for many plans with plan years ending in 2025. IRS guidance ties the fee to the average number of covered lives and the plan or policy year ending date. You can confirm current rates on the IRS PCORI fee guidance page.
| Plan or policy year ending date | PCORI fee rate per covered life | Common filing timing |
|---|---|---|
| On or after October 1, 2024 and before October 1, 2025 | $3.47 | Reported by July 31, 2026 if the plan year ended in 2025 |
| On or after October 1, 2025 and before October 1, 2026 | $3.84 | Calendar-year 2025 plans generally reported by July 31, 2026 |
For PCORI fee 2026 filers, the most common mistake is using the wrong plan-year rate. A calendar-year plan ending December 31, 2025 does not use the same rate as a plan ending June 30, 2025. If you are correcting a late or inaccurate filing, verify the plan year end date before calculating PCORI fees.
What Is Form 720, and Why Does PCORI Use It?
What is Form 720? IRS Form 720 is the quarterly federal excise tax return used to report many federal excise taxes, including environmental taxes, communications taxes, fuel taxes, manufacturers taxes and the PCORI fee. The IRS maintains an official About Form 720 page with current federal information.
Although Form 720 is called a quarterly federal excise tax return, the PCORI fee is reported once per year on the second quarter return, due July 31. This is why PCORI can feel different from other excise tax filing obligations.
You may see people search for IRS 720 form, Form 720 IRS, federal Form 720 or excise tax form 720. In the PCORI context, they generally mean the same reporting vehicle: the IRS return used to report and pay the IRS Form 720 PCORI fee.
If your organization does not already have an EIN, use the official IRS EIN application before filing. Do not file under an owner's SSN or an unrelated company EIN. If your team searches EIN IRS tools, make sure the EIN matches IRS records for the plan sponsor or filing entity.
Also, do not confuse IRS Form 720 with IRS Form 943. IRS Form 943 is for agricultural employer annual payroll tax reporting, not PCORI or excise tax form 720 reporting.
How the Penalty for Late Payment of Tax Is Calculated for PCORI
PCORI late payment charges follow the general IRS framework for unpaid federal tax. The exact notice amount can depend on when the return was filed, when payment was made, whether the IRS has already issued notices and whether reasonable cause applies.
| Charge | What it means | General calculation |
|---|---|---|
| Failure-to-file penalty | Applies when the required Form 720 was not filed on time | Usually 5% of unpaid tax per month or part month, up to 25% |
| Penalty for Late Payment of Tax | Applies when the tax was not paid by the deadline | Usually 0.5% of unpaid tax per month or part month, up to 25% |
| Interest | Applies to unpaid tax and may apply to penalties | Compounds daily using IRS quarterly interest rates |
| Penalty relief | Possible if you show reasonable cause | Requires a written explanation and supporting facts |
Because the Penalty for Late Payment of Tax is assessed on the unpaid amount, paying quickly can reduce additional monthly accrual. Interest is separate and continues until the balance is paid in full.
Here is a simplified example. Suppose a self-insured employer had 100 covered lives and owed $384 in PCORI fees for a calendar-year 2025 plan. If the employer paid two months late, the failure-to-pay amount before interest could be roughly $3.84, based on 0.5% per month for two months. If the Form 720 itself was also filed late, the failure-to-file penalty could be larger. The IRS notice controls the final amount.
How to fix a late PCORI fee payment
If you missed the deadline, act in the order the IRS usually cares about: file the return, pay the base tax, address interest and penalties, then request relief if you have a valid reason.
- Confirm the filing year and plan year: Identify the exact plan or policy year ending date. This determines the PCORI rate and which second quarter Form 720 applies.
- Calculate covered lives: Use an IRS-permitted counting method for the plan type. Keep worksheets, enrollment records and third-party administrator reports.
- File the original Form 720 if no return was filed: For PCORI, this is generally the second quarter Form 720 for the applicable filing year. Review the Form 720 IRS instructions guide if you need help understanding the filing flow.
- Pay the unpaid fee as soon as possible: Paying the base fee quickly helps stop additional Penalty for Late Payment of Tax accrual and limits further interest.
- Review whether Form 720-X is needed: If you filed Form 720 but reported the wrong amount, Form 720-X may be used for certain excise tax adjustments. Keep a copy of the original return and the correction.
- Request penalty relief when appropriate: If you had reasonable cause, such as a documented system transition, plan data delay or reliance issue that was corrected promptly, prepare a concise explanation for the IRS.
If you are correcting a prior year, keep the current instructions and the applicable prior-year guidance in your records. Searches like form 720 instructions 2025, instructions for Form 720 and IRS Form 720 PCORI can lead to different versions, so verify the tax period before relying on a PDF.
Where to Mail 720 Form if you choose paper filing
If you are searching where to mail 720 form, use the current IRS form 720 instructions before sending a paper return. Mailing addresses can change and may depend on whether payment is enclosed, whether you use a private delivery service and which tax period you are filing for.
Paper filing also increases the chance of timing issues because mail delays do not stop penalties if the return is considered late. If you file Form 720 online through an IRS-authorized e-file provider, you do not need to mail the paper return. You should still confirm how the tax payment will be made and retain proof of payment.
Common mistakes that lead to PCORI penalties
Many late PCORI issues come from process gaps rather than intentional noncompliance. These are the items to review before your next filing cycle:
- Treating PCORI as a regular quarterly payment instead of an annual second quarter filing
- Using the wrong PCORI rate for the plan year end date
- Assuming the insurer pays when the plan is actually self-insured
- Filing Form 720 but forgetting to pay the balance
- Using an incorrect EIN or filing under the wrong related entity
- Confusing Form 720 PCORI reporting with payroll forms such as IRS Form 943
- Missing a plan that changed funding status during the year
A clean PCORI filing process should include a July reminder, plan year documentation, covered-life calculation support, EIN verification and proof that the return and payment were submitted.

If you also file other federal excise taxes, such as fuel or manufacturers taxes, keep PCORI records separate from those recurring categories. PCORI is reported on the same return, but it has its own annual timing and covered-life calculation.
For late filings, your goal is not only to submit the return. Your goal is to create a clear record showing what was owed, when you found the issue, when you paid and why the delay happened. That record is useful if the IRS sends a notice or if you request penalty relief.
