S-Corp Schedule K-3 Exception: The New $250,000 Rule
If your S-corp has never filed Schedule K-2 or Schedule K-3, the 2025 tax year is the one that finally simplifies things. The IRS added a brand-new small S-corp exception: if your total receipts and total assets are each under $250,000, you skip both schedules regardless of your foreign activity. If you don’t clear that bar, the older Schedule K-3 exception is still available — it’s just narrower, and whether you qualify depends on what your shareholders ask for, and when. Here’s how both exceptions actually work, and where S-corp owners still get tripped up.
What Schedule K-2 and K-3 Report
Schedule K-2 is an extension of Form 1120-S, Schedule K. Schedule K-3 is the matching extension of each shareholder’s Schedule K-1. Together they report the items of international tax relevance your S-corp generated during the year — foreign source income, foreign taxes paid or accrued, ownership stakes in foreign corporations or partnerships, and foreign branches — broken out by shareholder so each one can complete their own foreign tax credit or reporting obligations correctly.
You don’t need foreign operations to get caught by this. A domestic-only S-corp that simply holds a brokerage account can trigger the filing requirement. If that account sits in a mutual fund or ETF that passes through even a small amount of foreign tax credit on a 1099-DIV, that’s foreign activity under the IRS instructions for Schedules K-2 and K-3, and it’s the single most common way a plain-vanilla S-corp ends up needing to think about this at all.
The Domestic Filing Exception’s Three Conditions
Before the 2025 changes, the broadest way out of filing Schedules K-2 and K-3 was the domestic filing exception, and it still applies if you don’t qualify for the new small S-corp rule below. (A narrower Form 1116 exemption also exists: if every shareholder is exempt from filing Form 1116 under section 904(j) and notifies the S-corp of that by the 1-month date, the schedules aren’t required either.) The domestic filing exception requires all three of the following for the tax year.
No or limited foreign activity. Your S-corp has no foreign activity at all, or its only foreign activity is passive category foreign income with no more than $300 of foreign income taxes treated as paid or accrued, shown on a payee statement like a 1099.
Shareholder notification. Every shareholder gets notice, no later than when you furnish their Schedule K-1, that they will not receive a Schedule K-3 unless they ask for one. This is usually a short statement attached to the K-1 — skip it and the exception doesn’t apply, no matter how clean your foreign activity numbers are.
No Schedule K-3 requests by the 1-month date. The 1-month date is one month before the date you actually file Form 1120-S — not one month before the unextended due date. File on extension in September and the 1-month date slides out to mid-August. If every shareholder stays silent through that date, you’re done. If even one asks for Schedule K-3 information on or before it, the exception fails for that year.
New for 2025: A Simpler Schedule K-3 Exception at $250,000
The 2025 Schedule K-2 and K-3 instructions add a second, much simpler path. If your S-corp’s total receipts for the year were under $250,000 and its total assets at year-end were under $250,000 — the same thresholds that let you skip Schedules L and M-1 under question 11 of Schedule B — you’re excepted from completing Schedules K-2 and K-3, period. Foreign activity doesn’t matter. The $300 foreign tax credit cap doesn’t matter. Size alone gets you out.
The notification requirement still follows you here. Even under the small S-corp exception, shareholders must still get notice — at the latest, attached to their Schedule K-1 — that they won’t receive a Schedule K-3 unless they request it. Treating the size test as a blanket pass and skipping the notice is the most likely way to lose an exception you’d otherwise qualify for.
What Happens If a Shareholder Asks for Schedule K-3
A request on or before the 1-month date breaks the exception, but only partially. You’re required to file Schedules K-2 and K-3 with the IRS and furnish Schedule K-3 to that requesting shareholder, completed only for the parts and sections relevant to their request. You don’t have to complete or furnish the rest of the schedule to anyone else. A request that arrives after the 1-month date doesn’t break the exception at all — you still don’t file with the IRS, but you owe that one shareholder a completed Schedule K-3 within a month of their request.
One more change worth knowing about. Shareholders used to have to renew their Schedule K-3 request every single year. Starting with the 2025 tax year, a shareholder can instead ask once to receive Schedule K-3 for 2025 and all subsequent years, which removes an easy-to-miss annual box from your K-1 process if you have a shareholder who consistently wants the information.
Why This Doesn’t Mean You’re Off the Hook
Qualifying for an exception to filing Schedules K-2 and K-3 isn’t the same as having no international tax exposure. A shareholder who claims a foreign tax credit on their own return can still need information from your S-corp to complete Form 1116, whether or not the corporation itself ever files anything. And the penalties that apply to Form 1120-S and Schedule K-1 for missing or incomplete information apply equally here — the exception has to actually be satisfied, not just assumed, before you rely on it. If your S-corp has any ownership stake in a foreign entity, see our breakdown of how S-corps can hold interests in foreign subsidiaries for how that changes the analysis. And if you’re used to thinking about small-entity exceptions through the lens of the BOI reporting rollback, our piece on the BOI exemption for S-corps walks through a similar size-based carve-out.
The real complexity here isn’t the math — it’s knowing which of your shareholders’ brokerage statements, K-1s from other entities, or foreign accounts quietly created foreign activity you didn’t track. That’s a conversation worth having before your extension deadline, not after a shareholder calls asking where their Schedule K-3 is.
