The 10-return e-file mandate, and how the 10 is counted

The threshold is not new any more, but the way it is counted still surprises people every January. The IRS states it in one sentence: as of tax year 2023, if you have 10 or more information returns, you must file them electronically.

The number that replaced was 250, and under the old rule 250 was applied separately to each type of return. That is the part that changed, and it is the part that matters to a small firm.

The 10 is a total, not a per-form count

The final regulations require filers to aggregate almost all information return types covered by the regulation to determine whether a filer meets the 10-return threshold. The IRS's own worked example is four Forms 1098 plus six Forms 1099-A: neither is 10, the sum is, and both must be e-filed.

Forms W-2 count toward the total even though they go to the Social Security Administration rather than the IRS. A bookkeeping practice with eight W-2s and three 1099-NECs has eleven returns and a mandate, and would not have guessed that from either number alone.

So the practical question in November is not 'how many 1099s does this client have' but 'how many information returns does this filer produce in total for the year, across every form'. Ask it once, per filer, and the answer decides paper or electronic for all of them.

Where the rule comes from

The regulation

T.D. 9972, the final e-file regulations, which reduce the 250-return threshold enacted in prior regulations to generally require electronic filing by filers of 10 or more returns in a calendar year.

When it took effect

Returns required to be filed in 2024 and after (that is, as of tax year 2023).

What is aggregated

Almost all information return types covered by the regulation, including Forms W-2 e-filed with the Social Security Administration.

What the mandate does not change

It does not move a due date. Electronic filing buys a 1099-MISC extra time with the IRS (February 28 on paper against March 31 electronically), but the 1099-NEC's date is the same either way, and no channel changes the date a recipient statement has to be in the recipient's hands.

It does not create an extension. An automatic 30-day extension of time to file is requested on Form 8809, and it must be filed by the due date of the returns to get the extension. For Forms W-2 and 1099-NEC, no automatic extension is available. That carve-out is in the general instructions and it is the one most likely to matter to a firm filing nonemployee compensation.

An extension of time to furnish the recipient statements is a different request on a different form: Form 15397, Application for Extension of Time to Furnish Recipient Statements, which must be requested online or by fax only.

What it costs to be wrong

The information-return penalty is charged per return, for each one filed late or incorrectly, and separately per payee statement not furnished correctly and on time. For returns required to be filed in 2027 the tiers are $60 up to 30 days late, $130 from 31 days through August 1, and $340 after August 1 or not filed. Intentional disregard is the greater of $690 per return or 10% of the amount that should have been reported, with no maximum.

A practice with forty returns across a handful of clients is therefore not looking at a nuisance figure. That arithmetic, more than the mandate itself, is why January discipline pays for itself.

One more reason the count matters this year

From January 1, 2027, electronic is not merely mandatory above ten returns: there is one electronic system and no other. The IRS says that IRIS will be the only information returns electronic filing system, including current year, prior year, or corrections, after Jan. 1, 2027, and that the last day to file through the older FIRE system is Nov. 19, 2026, at 3 p.m. ET.

A firm that has been under the threshold and filing on paper is not affected by that. A firm that is over it and has filed through FIRE has a move to make before anything else about this season matters: its own IRIS registration if it will transmit itself, or a service that files through IRIS if it will not.
