Why a PCORI Form 720 Gets Rejected
A rejected return fails something specific. The IRS publishes the rules it runs on e-filed Form 720s, and for PCORI they mostly test arithmetic, the quarter, and identity. If your PCORI Form 720 was rejected, the rule number on the reject message tells you which check failed. This guide translates the ones PCORI filers are most likely to meet, from the IRS 2026 Q4 rule publication (version 1.0).
A rejection is different from a return that was accepted but wrong. For a rejection, you fix the return and send it again. For an accepted return with an error, you use Form 720-X. More on that below.
Rules F720-181 to F720-185: math on each PCORI line
All five of these are "Math Error" rules with a severity of "Reject." Line 133 has four sub-lines. Our guide to line 133 explains which one is yours.
| Rule | What it requires | Plain meaning |
|---|---|---|
| F720-182 | Fee on 133(a) = average lives x rate | Insured, earlier rate |
| F720-183 | Fee on 133(b) = average lives x rate | Insured, later rate |
| F720-184 | Fee on 133(c) = average lives x rate | Self-insured, earlier rate |
| F720-185 | Fee on 133(d) = average lives x rate | Self-insured, later rate |
| F720-181 | IRS No. 133 Tax = sum of fees on 133(a) to (d) | The total must add up |
Here is how a return could trip them. The sponsor and numbers below are made up, and the rates are from the June 2026 form. A sponsor has two self-insured plans with different year ends:
| Line | Average lives | Rate | Correct fee |
|---|---|---|---|
| 133(c) | 100 | $3.47 | $347.00 |
| 133(d) | 412 | $3.84 | $1,582.08 |
| IRS No. 133 Tax | $1,929.08 |
- Rounding 133(d) to $1,582 means the fee no longer equals 412 x $3.84, so on the rule's wording it fails F720-185.
- Entering only the 133(d) fee as the IRS No. 133 Tax fails F720-181. The Tax line must combine both.
- Changing the lives after computing the fee, and forgetting to update the fee, fails the line's product rule.
Check the fee for each line with the PCORI fee calculator. Remember which rate applies, too. These rules test the product of what's on the line, so read the plan year labels on the form, and see how the PCORI fee is figured.
Rule F720-210-04: the wrong quarter
This one catches filers who treat PCORI like any other quarterly tax. In plain terms: if IRS No. 133 has a non-zero amount, the quarter ending in the return header must be 2025-06 or 2026-06. Its status in the publication is "New." The earlier version, F720-210-03, allowed 2024-06 or 2025-06 and is now deleted.
- PCORI entered on a September or December quarter return: fails. The instructions also say not to make an entry on the IRS No. 133 line on first-, third-, or fourth-quarter filings.
- Quarter set to a plan year's end month, such as December 2025: fails. The return's quarter isn't your plan year end. The fee goes on a June quarter return.
- A June quarter older than those listed: fails under the current wording.
This rule list doesn't name 2027-06 yet. The return due August 2, 2027 is still ahead, and the earlier rule's replacement shows the IRS updates this list over time. We won't guess at the next version, so check the rule in force when you file.
EIN, name, and duplicate return rejections
These aren't specific to PCORI, but a once-a-year filer is more likely to hit them, because the details have had a year to go stale.
| Rule | What triggers it | What to do |
|---|---|---|
| R0000-922-01 | EIN and name control don't match the IRS e-file database | Enter the legal name the IRS holds for that EIN |
| R0000-914-01 | An accepted e-filed return already exists for that EIN and quarter | Don't resend. Correct with Form 720-X if needed |
| R0000-915-01 | An accepted paper return already exists for that EIN and quarter | Same as above |
| R0000-194 | Submission duplicates one already accepted | Check your acknowledgment first |
| R0000-007-02 | ZIP code doesn't fit the state | Fix the address |
Rules also test the totals in Part III. Line 3 must equal the Part I and Part II totals (F720-034-01), line 8 must equal lines 5 plus 6 (F720-036-01), line 9 must equal lines 4 plus 8 (F720-037-01), and line 10 must equal line 3 minus line 9 when a balance is due (F720-038-01). A Part II total that leaves out PCORI fails F720-158-03. Filers who pay by electronic funds withdrawal should also know FPYMT-031-01: the payment can't exceed the line 10 balance.
How to fix a rejected return and refile
- Find the rule number on the reject message, and match it to the tables above or to the IRS rule publication.
- Correct the specific entry on the same return. For a math rule, recheck lives, rate, and fee on every 133 line in use, then the Tax line and Part III.
- Resubmit, and wait for the result. Our sources don't grant added time after a rejection, so don't leave this for later if the due date is close. The next PCORI due date is August 2, 2027.
- Save the final accepted acknowledgment with your records.
Catching these before you submit
The errors above are mostly arithmetic and setup mistakes. When you file your PCORI fee online with EasyFile720, rates for the return are built in and the math is calculated after you enter your covered lives. Validations catch common mistakes before you submit. No software can promise acceptance, and name or EIN data still has to match IRS records, so check those against your IRS paperwork. Once the return is accepted, you get an electronic acknowledgment from the IRS, and the return stays saved in your account. If your rejected return came from somewhere else, or you are starting fresh, your next step is to create a free account, with no credit card needed to start, and pay $39.95 when you file.

FAQ
Does a rejected return count as filed?▼
Rejected means the IRS did not accept that submission, so you have no acceptance acknowledgment for it. Our sources give no extra time after a rejection, so correct and resubmit promptly.
Does an accepted return mean my covered lives are correct?▼
No. The published PCORI rules test arithmetic and the quarter. They do not check how you counted lives, so keep your worksheet.
Do these rules apply to a paper Form 720?▼
They are published for IRS Modernized e-File submissions. Our sources do not describe how a paper return is checked.
Will the rule list change for the 2027 filing?▼
It may. The quarter rule was already revised once, moving from 2024-06 and 2025-06 to 2025-06 and 2026-06, and the current list does not yet name 2027-06. Check the rule in force when you file.
