PCORI: E-File or Mail Form 720?

The IRS does not require e-filing for this fee. IRS Q&A 8 says "Electronic filing is available but not required," and the excise e-file page calls Form 720 "available for optional electronic filing." So PCORI filing online and mailing a paper return are both valid, and the choice is yours.

The honest difference comes down to cost against proof. Mailing is cheap, but your evidence is about when you sent it. E-filing has a provider fee, but you hear back from the IRS. Here is how the two compare, using only what the IRS has published.

Form 720 electronic filing and mail, side by side

Your due date doesn't change. The next one is Monday, August 2, 2027, for the PCORI return covering plan years that ended in 2026.

Proof of filing: the deciding point

Think about the question you might face in two years: "How do you know you filed this on time?"

With mail, the instructions give you the "timely mailing as timely filing/paying" rule. You send the return using the U.S. Postal Service or a designated private delivery service. A delivery service "can tell you how to get written proof of the mail date." That shows when it left your hands. Our sources don't describe any response from the IRS confirming a paper return was received.

With e-file, the IRS describes "immediate acknowledgement of receipt and faster service." The return either comes back accepted or rejected. An accepted return gives you a dated record from the IRS itself, which you can keep with your covered-lives worksheet.

If the person filing changes from year to year, which is common with HR staff, a record like that is easy to hand over. So is a saved copy of a mailed return, as long as someone actually kept it along with the mail receipt.

What each route does about mistakes

An e-filed return runs against IRS business rules. Several apply directly to PCORI. The fee on each of lines 133(a) through 133(d) must equal average lives times the rate, the IRS No. 133 tax must equal the sum of those fees, and the return must be for an allowed June quarter. If a rule fails, the return is rejected and you can fix it and resubmit.

Those rules apply to e-filed returns. Our sources don't describe how a math or quarter error on a paper return would surface or when you would learn of it. The upside of the e-file route is finding out while there may still be time before the due date.

Neither route tests whether your covered-lives count is right. Our covered lives guide helps with that part.

When mailing is the sensible choice, and when it isn't

Mailing is a reasonable pick if:

• You have a simple return, and you are confident in the form and math.
• Saving the provider fee matters more to you than having an IRS acknowledgment.
• You are comfortable paying by check with Form 720-V, or through Direct Pay or EFTPS.
• You are sending it well ahead of the due date and will keep proof of the mail date.

Mail carries more risk if:

• You are close to the deadline. Using a delivery service has its own wrinkle: the instructions say delivery services can't deliver to P.O. boxes, so check IRS.gov/PDSStreetAddresses for the right address.
• You are a first-time filer who wants the fee and rate checked before it goes in.
• You file for several clients, and a paper trail per client is more work.
• You want to pay by electronic funds withdrawal, which the instructions tie to filing electronically.

Payment is due when the return is due on either route. A mailed return can go with a check and Form 720-V, or you can pay separately by Direct Pay or EFTPS and leave the voucher out. An e-filed return adds electronic funds withdrawal as an option.

Whichever you choose, the fee is the same. The route you take doesn't change your rate or your lives count, and you can check the amount with the PCORI fee calculator.

What e-filing with EasyFile720 involves

To e-file, the IRS says you select an approved provider and pay its service fee. You can also read the IRS excise e-file page for the program itself.

That acknowledgment is the proof point discussed above, and past returns stay saved in your account.

Creating an account is free, with no credit card needed to start, and the cost is $39.95 per filing, paid when you file.
