Which PCORI Counting Method Should You Use?
Choose the PCORI counting method that matches the data you already have and can defend. A self-insured plan sponsor has three options: actual count, snapshot, and Form 5500. The IRS doesn't rank them, and your covered lives figure can differ under each. This guide compares them, runs a single plan through all of them, and gives you a short way to decide.
How do the methods compare?
| Actual count | Snapshot | Form 5500 | |
|---|---|---|---|
| Data needed | Lives for each day of the plan year | Lives or tier counts on matching dates each quarter | Beginning and ending participant totals on the form |
| Counts dependents by | Each actual person | Each person (count) or 2.35 per non-self-only participant (factor) | Doubling effect when family coverage is offered |
| Main condition | Complete dated records | Dates within three days of the matching date, all in the plan year | Form filed no later than the fee due date |
| Picks up mid-year changes | All of them | Only as of each date | Only the start and end totals |
| Work required | Highest, unless your system exports dates | Moderate | Lowest, if the form is filed in time |
Insurers have a different list, which adds member months and the state form method and has stricter consistency rules. This guide is for plan sponsors. If you need more on any one calculation, see the covered lives guide.
One plan, four different fees
Here is a made-up self-insured plan with family coverage. Its plan year ended September 30, 2026, so the rate is $3.84. Over the year it grew from 350 to 389 participants.
| Method | How the number is reached | Lives | Fee at $3.84 |
|---|---|---|---|
| Snapshot factor | Four dates: 620, 665, 670, 713, total 2,668, divided by 4 | 667 | $2,561.28 |
| Snapshot count | Four dates: 630, 660, 680, 714, total 2,684, divided by 4 | 671 | $2,576.64 |
| Actual count | 245,280 covered-life days divided by 365 | 672 | $2,580.48 |
| Form 5500 | 350 + 389, with no division because family coverage is offered | 739 | $2,837.76 |
The gap from lowest to highest here is $276.48. Don't read this as "Form 5500 always costs more." It depends on your mix of coverage.
Here is the arithmetic. For a plan with family coverage, the Form 5500 method counts each participant about twice. The snapshot factor counts self-only participants once and others 2.35 times. So those two reach about the same number when there are roughly three other-coverage participants for each self-only participant. With more self-only participants than that, as in this plan, Form 5500 gives a higher number. With fewer, it gives a lower one. A plan that offers only self-only coverage divides by 2, so this comparison doesn't apply to it.

How do you decide?
- Is your only self-insured plan an HRA or health FSA? Use the special rule that treats each participant as one life, then pick the simplest method for counting participants. Our HRA and FSA post has more.
- Will a Form 5500 or 5500-SF be filed by the fee due date? If not, Form 5500 is off the table for this year. If so, it is likely the least work. Then check whether your coverage mix makes it costly.
- Can you get enrollment by coverage tier on set dates? Then the snapshot factor works without dependent data.
- Do you have reliable dependent records? Then snapshot count or actual count reflects your real enrollment.
- Did enrollment swing sharply during the year? Actual count picks up every change, while a few dates can miss a short-lived spike or dip, in either direction.
Which rules change your count under any method?
Before comparing methods, get the group of people right, because these rules can move your number more than the method does:
- Insured options. If a plan offers both fully insured and self-insured options, the regulation lets you disregard lives covered solely under the insured options, and it says so for all three methods.
- Combined arrangements. Self-insured arrangements with the same sponsor and same plan year may be treated as one plan, so a person on both counts once. A separate medical plan and drug plan is the regulation's example.
- Former employees. COBRA participants and retirees count under IRS Q&A 6, so a report limited to active employees will come up short under any method.
- Short plan years. The fee still applies, based on the average lives during that shorter plan year.
What does the consistency rule require?
The regulation is short on this point: a plan sponsor must use the same method "consistently for the duration of the plan year," and "may use a different method from one plan year to the next." In practice:
- You can't use snapshot dates for part of a plan year and daily counts for the rest.
- Switching next year is allowed. The regulation's own example moves from snapshot count to the snapshot factor across two plan years.
- Plan ahead for snapshot. Its dates must fall within the plan year, so you need enrollment records for those dates.
Your next step once you have chosen
Run your method, save the worksheet, and report the average on the second-quarter Form 720: line 133(c) at $3.47 or 133(d) at $3.84 on the June 2026 form. Plan years ending in 2026 are due Monday, August 2, 2027, because July 31, 2027 is a Saturday. The IRS publishes the rate for plan years ending on or after October 1, 2026, so check the second-quarter 2027 instructions for those.
EasyFile720 doesn't choose the method or count lives for you. That decision and count are yours. Once you have the number, you can file your PCORI fee online in a guided filing: enter your figures, and the rates are built in and the math is calculated. Validations catch common mistakes before you submit, you sign electronically, and your past returns stay saved, so next year you can see what you reported.

FAQ
Am I allowed to choose the method that gives the lowest fee?▼
The regulation lets a sponsor use any of the three and doesn't say which to choose. You must follow the chosen method consistently for the whole plan year, and its conditions must be met, such as the Form 5500 filing date.
Do I have to tell the IRS which method I used?▼
The instructions we reviewed tell you to report the average number of lives covered on Form 720 and don't describe a place to name the method. Keep your worksheet and records with your files.
Can different plans of mine use different methods?▼
The sponsor regulation states the consistency rule for a plan and a plan year. The stricter same-method-across-all-policies rule appears in the insurer regulation. If your plans are combined into one, use one method for the combined plan.
Which method applies to an HRA-only employer?▼
Any of the three, along with a special rule that lets you treat each participant as one life when the HRA or health FSA is your only self-insured plan.
