Schedule K-2 is the international supplement to Form 1120-S that reports an S corporation’s items of international tax relevance to the IRS, while Schedule K-3 delivers each shareholder’s slice of those same items. You file Schedule K-2 when your S corporation has foreign activity, foreign owners, or shareholders who need international information to claim a foreign tax credit, even when the activity is small or indirect.
According to the IRS Statistics of Income, more than 5.1 million S corporations filed Form 1120-S in the most recent tax year, and the IRS estimates that millions of those returns now require Schedule K-2 or K-3 reporting because of expanded international relevance rules issued under Notice 2021-39 and the 2024 instructions update.
Here is what you will learn in this guide:
- 📑 How every part of Schedule K-2 maps to your S corporation’s books and what each line really wants.
- 🌍 When the Domestic Filing Exception lets you skip K-2 and K-3 entirely, and when it traps you.
- ⚖️ How federal rules under IRC §6038, §6698, and §6722 create real penalties when you miss a box.
- 🧾 How named-person scenarios show the right way to complete Parts I, II, III, and the rarer Parts IV–XIII.
- 🛡️ How to avoid the seven most common mistakes that trigger IRS notices and shareholder amended returns.
What Schedule K-2 Is and Why It Exists
Schedule K-2 is a 20-plus page schedule attached to Form 1120-S that breaks out every item of international tax relevance at the entity level. Before tax year 2021, S corporations reported foreign items on a single line of Schedule K and attached free-form statements. The IRS found that approach produced inconsistent data, missed foreign tax credit information, and forced shareholders to guess at allocations.
The agency replaced that line with a structured schedule in final regulations under Treasury Decision 9959, and the 2025 Schedule K-2 instructions now divide international reporting into 13 parts. The plain-English purpose is uniform data: the IRS, the shareholder, and the shareholder’s preparer all read the same numbers in the same boxes.
The consequence of ignoring Schedule K-2 is severe because the IRC §6698 penalty for an incomplete S corporation return runs $245 per shareholder per month for up to 12 months for the 2025 tax year, and the IRC §6722 penalty for a missing K-3 to a shareholder adds another $310 per failure.
A real-world example shows the stakes. Maria Delgado runs Delgado Imports, an S corporation with three shareholders and a small Canadian distributor. She thinks the Canadian sales are too small to matter and skips Schedule K-2. Twelve months later the IRS issues a CP162 notice for $8,820 in §6698 penalties and another $930 in §6722 penalties.
A common misconception is that Schedule K-2 only applies to large multinational S corporations. The IRS clarified in its 2022 FAQ that even an S corporation with no foreign activity may need to file when a shareholder needs information for a foreign tax credit on Form 1116.
Where Schedule K-2 Sits Inside Form 1120-S
Schedule K of Form 1120-S still lives on pages 3 and 4 of the main return. Schedule K-2 is a separate PDF the IRS posts on its forms portal and a parallel schedule named K-3 goes to each shareholder. The two schedules track each other line for line.
Filing happens electronically through the Modernized e-File system the same day you transmit Form 1120-S, which is normally March 15 for calendar-year S corporations. A six-month extension via Form 7004 covers the K-2 and K-3 too.
The consequence of late filing extends to the shareholder level because a shareholder cannot finalize their personal Form 1116 or Form 8621 without the K-3, and that ripple often forces shareholders to file Form 4868 extensions on April 15.
Who Must File Schedule K-2 and Schedule K-3
Every S corporation with items of international tax relevance must file Schedule K-2 unless it qualifies for the Domestic Filing Exception. The phrase international tax relevance is broad on purpose, and the IRS instructions define it to include foreign source income, foreign taxes paid, foreign assets, foreign partners, and even certain pass-through interests in foreign corporations.
The plain-English rule is that if any shareholder might need to file Form 1116, Form 8621, Form 5471, Form 8865, Form 8858, or Form 8992 because of the S corporation’s activity, you file Schedule K-2.
The consequence of guessing wrong is the §6698 penalty plus shareholder-level penalties for missing international forms, and the IRS will not accept we did not know as reasonable cause once the schedule has been law for four full filing seasons.
A real-world example involves Andrei Petrov, a Lithuanian green-card holder who owns 40 percent of a U.S. S corporation that earns only domestic income. Even though the S corporation has zero foreign activity, Andrei needs the K-3 to confirm there is no foreign source income on his Form 1040, so the entity must still file at least Parts I and II.
A common misconception is that no foreign activity equals no K-2. The 2024 instructions make clear that shareholder status alone can trigger filing, and the Domestic Filing Exception is the only complete escape hatch.
The Domestic Filing Exception
The Domestic Filing Exception lets a purely domestic S corporation skip K-2 and K-3 when it meets four criteria. First, the S corporation has no foreign activity or limited foreign activity, where limited means under $300 of foreign tax. Second, all direct shareholders are U.S. citizens, U.S. resident individuals, domestic estates, certain domestic trusts, S corporations, single-member LLCs owned by these persons, or 501(c)(3) organizations.
Third, the S corporation must notify shareholders in writing by the date it furnishes Schedule K-1, telling them they will not receive a K-3 unless they ask. Fourth, no shareholder requests a K-3 by the one-month date, which is one month before the S corporation files Form 1120-S.
The plain-English consequence of missing any one of the four criteria is that the exception disappears and you must file the full K-2 and K-3 for every shareholder. The IRS has not announced a transition penalty waiver for the 2025 filing season, so the §6698 and §6722 penalties apply in full.
A real-world example features Jordan Reed, who runs Reed Bakery, a domestic S corporation with two U.S. shareholders. Jordan posts the no-K-3 notice on the company portal in February but never confirms the partner read it. The partner later requests a K-3 in April, after the one-month date, but Jordan still must produce one because the request itself defeats the exception once the schedule shows any foreign source income.
A common misconception is that limited foreign activity allows up to $300 of foreign source income. The actual rule, per the final 2024 instructions, caps foreign tax at $300, not foreign income, and the income must be passive category income reported on a qualified payee statement.
The 13 Parts of Schedule K-2 Explained
The Schedule K-2 form is divided into 13 parts, and each part has a matching Schedule K-3 part that flows to the shareholder. The parts cover everything from a basic foreign-source income breakdown to the corporate alternative minimum tax items added under the Inflation Reduction Act of 2022.
Most S corporations only complete Parts I, II, and III. The remaining parts apply to specific structures like controlled foreign corporations, passive foreign investment companies, and foreign-derived intangible income elections.
The plain-English consequence of skipping a required part is that the IRS treats the schedule as incomplete, and an incomplete schedule triggers the same §6698 penalty as a missing schedule.
Part I – Information on Partner
Part I asks identifying questions that turn on or off the rest of the schedule. You check boxes for items like gain on personal property sale, foreign oil and gas taxes, high-taxed income, Form 8858 information, and Form 5471 information. The 2025 Part I checklist has more than a dozen boxes.
The plain-English rule is that every box you check forces you to complete the matching later part. The consequence of leaving a box unchecked when the activity exists is that the IRS will challenge the related shareholder credit during examination.
A real-world example involves Priya Shah, who skips the high-taxed income box even though her S corporation pays a 32 percent Indian withholding tax. Her shareholders later lose the high-tax kick-out election under Reg. §1.904-4(c) because Part III does not properly categorize the income.
Part II – Foreign Tax Credit Limitation
Part II builds the numerator and denominator for the shareholder’s §904 limitation. Section 1 of Part II reports gross income by source and category, and Section 2 reports deductions allocated and apportioned to that income. The categories track the standard four buckets: passive, general, foreign branch, and §951A (GILTI).
The plain-English consequence of mis-categorizing income is that the shareholder’s Form 1116 cap is wrong and the foreign tax credit either disappears or shifts to a future year. The IRS audit lookback runs three years for income misallocation but six years when the misallocation exceeds 25 percent of gross income under §6501(e).
A real-world example: Tom Bianchi’s S corporation earns rental income in Italy and reports it as general category. The income is passive, so when Tom’s shareholders prepare Form 1116, they over-claim general category credit and trigger a CP2000 notice 18 months later.
A common misconception is that Part II just copies Schedule K. The categories on Schedule K-2 are far more detailed, including separate columns for U.S. source, foreign source by country, sourced by partner, and other.
Part III – Other Information for Preparation of Form 1116 or 1118
Part III is where the foreign tax credit calculation actually happens for the shareholder. Section 1 reports research and experimental expense apportionment under Reg. §1.861-17. Section 2 reports interest expense apportionment under Reg. §1.861-9. Section 3 reports foreign-derived intangible income deduction-eligible income.
Section 4 lists foreign taxes paid or accrued by country and category. Sections 5 and 6 cover §986(a) translation and §905(c) redeterminations.
The plain-English consequence of leaving Part III blank when foreign taxes exist is that the shareholder cannot claim a foreign tax credit at all because Form 1116 line 8 requires the country-by-country detail.
A real-world example: Lena Park’s S corporation pays $4,200 of Korean withholding tax. She reports the total on Schedule K but leaves Part III Section 4 blank. Her shareholders cannot complete Form 1116 line 8, so they lose the credit and pay double tax.
Part IV – Information on Section 250 Deduction for Foreign-Derived Intangible Income
Part IV applies only when the S corporation generates foreign-derived intangible income. The §250 deduction is normally a C corporation benefit, but a shareholder who is itself a C corporation can claim a portion of the deduction through the S corporation.
The plain-English consequence of skipping Part IV when a C corporation shareholder exists is that the shareholder loses a deduction worth 37.5 percent of qualifying foreign-derived income through 2025.
Part V – Distributions From Foreign Corporations to Partnership
Part V reports distributions from foreign corporations to the S corporation, including previously taxed earnings and profits under §959. The schedule splits distributions into PTEP and non-PTEP columns.
The consequence of mis-reporting PTEP is that shareholders pay tax twice on income already taxed under subpart F or GILTI rules. A real-world example: Carlos Mendoza’s S corporation owns a Mexican CFC and receives a $50,000 distribution that is 100 percent PTEP. If Part V leaves the PTEP column blank, the shareholders treat the distribution as a fully taxable dividend.
Part VI – Information on Partner’s Section 951(a)(1) and Section 951A Inclusions
Part VI reports subpart F income inclusions under §951(a)(1) and GILTI inclusions under §951A. Each shareholder needs the inclusion amount, the related foreign taxes, and the Q-BAI (qualified business asset investment) figure.
The plain-English consequence of incomplete Part VI is that the shareholder cannot complete Form 8992 to compute their GILTI tax, and the IRS may assess GILTI on the gross inclusion without the §250 deduction or §960 deemed-paid credit.
Part VII – Information to Complete Form 8621
Part VII helps shareholders meet the passive foreign investment company reporting rules. The S corporation reports each PFIC’s name, EIN or reference ID, ordinary earnings, net capital gain, and any QEF or mark-to-market election information.
A common misconception is that PFIC reporting only matters for hedge fund partners. Many ordinary foreign mutual funds qualify as PFICs, so an S corporation that holds foreign ETFs in its treasury account triggers Part VII.
Part VIII – Partnership’s Interest in Foreign Corporation Income (Section 960)
Part VIII feeds the deemed-paid foreign tax credit under §960. The schedule lists each foreign corporation, the income groups, and the foreign taxes that follow the income up to the U.S. shareholder.
The consequence of mis-grouping income is that the §904 limitation goes to the wrong basket and the credit may be denied entirely.
Part IX – Partner’s Information for Base Erosion and Anti-Abuse Tax
Part IX reports base erosion payments under §59A. BEAT applies to applicable taxpayers with three-year average gross receipts over $500 million, so Part IX is rare for S corporations but possible when an S corporation has large C corporation shareholders.
Part X – Foreign Partners’ Character and Source of Income and Deductions
Part X reports income effectively connected with a U.S. trade or business and U.S. source FDAP income for foreign shareholders. A foreign person cannot directly own S corporation stock under §1361(b)(1)(C), so Part X most often applies to a non-resident alien shareholder of a domestic LLC that is itself an S corporation shareholder through a grantor trust structure.
Part XI – Section 871(m) Covered Partnerships
Part XI is reserved at present and applies to dividend equivalent payments under §871(m). Most S corporations leave Part XI blank.
Part XII – Reserved for Future Use
Part XII is currently reserved. The IRS uses reserved parts as placeholders for upcoming international rules. Leave it blank for the 2025 filing season.
Part XIII – Foreign Partner’s Distributive Share of Deemed Sale Items on Transfer of Partnership Interest
Part XIII covers deemed sales under §864(c)(8), which generally applies to partnerships rather than S corporations, so this part is almost always blank for an S corporation. It exists on the form because the IRS uses one schedule template across Forms 1065, 1120-S, and 8865.
Step-by-Step Walkthrough of Schedule K-2
This walkthrough assumes a calendar-year S corporation with foreign source income, foreign tax paid, and U.S. shareholders. Adjust the steps if your structure differs.
Step 1 – Gather Source Documents
Pull every Form 1042-S, country tax voucher, foreign withholding certificate, and brokerage 1099-DIV showing foreign tax paid. Pull general ledger detail for foreign sales, foreign expenses, and any intercompany payments to a related foreign entity.
The consequence of missing one source document is a wrong category on Part II and a denied credit on the shareholder’s Form 1116. A real-world example: Sofia Lindgren forgets a Swedish 1042-S that reports $1,800 of withholding because the broker mailed it to the corporation’s old address.
Step 2 – Complete Part I Checkboxes
Walk through every checkbox in Part I and mark the ones that apply. Each check tells the IRS which later parts to expect.
Step 3 – Build the Part II Sourcing Worksheet
Allocate every dollar of gross income between U.S. source and foreign source under §§861 through 865. Within foreign source, split among passive, general, foreign branch, §951A, and other categories.
Step 4 – Apportion Deductions in Part II Section 2
Apportion deductions to the income they generate under Reg. §1.861-8. Direct deductions follow the income directly. Indirect deductions like interest and overhead apportion using gross income or asset methods.
Step 5 – Populate Part III Foreign Tax Detail
List every foreign tax paid by country, by category, and by date paid or accrued. Translate to U.S. dollars using the §986(a) rules.
Step 6 – Address Parts IV Through XIII as Needed
Complete each remaining part triggered by your Part I checkboxes. Skip the parts that do not apply.
Step 7 – Generate Schedule K-3 for Each Shareholder
Schedule K-3 mirrors K-2 but reports each shareholder’s distributive share. Allocate by ownership percentage unless a special allocation applies, which is rare for S corporations because of the single-class-of-stock rule.
Step 8 – E-File With Form 1120-S
Transmit Schedule K-2 and every Schedule K-3 with the main Form 1120-S through Modernized e-File by the March 15 deadline or the September 15 extended deadline.
Three Real-World Scenarios
The three scenarios below show how a typical S corporation handles common Schedule K-2 questions.
Scenario 1 – Limited Foreign Tax, Domestic Shareholders
| Trigger Event | Filing Outcome |
|---|---|
| S corporation receives $220 of French withholding on a money market fund | Domestic Filing Exception available if shareholder notice is sent on time |
| All four shareholders are U.S. citizens | Exception still available |
| One shareholder requests K-3 by the one-month date | Exception lost; full K-2 and K-3 required for every shareholder |
| S corporation files only Schedule K-2 Parts II and III | Penalty risk under §6698 because Part I checkboxes are incomplete |
Scenario 2 – Foreign Subsidiary CFC
| Structural Fact | Required Schedule K-2 Action |
|---|---|
| S corporation owns 100 percent of a Mexican S.A. de C.V. | File Form 5471 plus K-2 Part VI for GILTI |
| CFC distributes $40,000 of PTEP | Complete K-2 Part V PTEP column |
| CFC pays $9,000 Mexican corporate tax | Complete K-2 Part VIII for §960 credit |
| Shareholders are individuals | Inform shareholders that §962 election may save tax |
Scenario 3 – Foreign Mutual Fund Holding
| Investment Activity | Schedule K-2 Response |
|---|---|
| S corporation buys €100,000 of an Irish UCITS ETF | UCITS treated as PFIC under §1297 |
| Fund earns $3,200 ordinary income | Complete Part VII with PFIC reference ID |
| Shareholders make QEF election | Provide annual information statement attached to K-3 |
| Fund distributes $1,500 cash | Track for excess distribution analysis under §1291 |
Named Examples Showing Right and Wrong Approaches
Hannah Brooks runs Brooks Consulting, a two-shareholder S corporation, and earns $9,000 of consulting fees from a German client. Hannah classifies the income as foreign source general category on Part II Section 1 because the services are performed remotely from Germany under §861(a)(3). Her shareholders claim the German tax on Form 1116 without issue.
Marcus Webb owns Webb Tech, an S corporation with a Canadian sales office. He treats the office as a foreign branch and reports the income on Part II in the foreign branch category. Marcus also files Form 8858 for the foreign disregarded entity and checks the Form 8858 box on Schedule K-2 Part I.
Elena Rossi manages Rossi Imports, which holds a 12 percent interest in an Italian S.r.l. The interest is below the CFC threshold under §957 but qualifies as a PFIC because the Italian entity earns mostly passive income. Elena completes Part VII for every shareholder and provides annual QEF statements.
Mistakes to Avoid
Avoid these seven mistakes to keep your Schedule K-2 clean and your shareholders out of IRS trouble.
- Skipping Schedule K-2 because the S corporation has no foreign activity. The Domestic Filing Exception still requires the shareholder notice and the one-month date check, and missing either one defeats the exception.
- Treating limited foreign activity as $300 of foreign income. The cap is $300 of foreign tax, not income, and the income must be passive category from a qualified payee statement.
- Mis-categorizing rental real estate income as general category. Rental income is passive category under §904(d)(2) and belongs in the passive column.
- Leaving Part III Section 4 blank when foreign taxes exist. The country-by-country detail is mandatory, and shareholders cannot complete Form 1116 line 8 without it.
- Forgetting to translate foreign tax to U.S. dollars at the correct §986(a) date. Using year-end rates for accrued taxes instead of the average exchange rate creates a §905(c) redetermination two years later.
- Allocating deductions only to U.S. source income to inflate the foreign tax credit. The IRS audits this pattern aggressively under Reg. §1.861-8 and can disallow the entire credit.
- Ignoring PFIC status for foreign mutual funds. A UCITS, SICAV, or foreign ETF is almost always a PFIC, and missing Part VII exposes shareholders to the punitive §1291 excess distribution regime.
Do’s and Don’ts
Apply these do’s and don’ts every filing season.
- Do send the shareholder notice for the Domestic Filing Exception by the date you furnish Schedule K-1, because timely notice is one of the four mandatory criteria.
- Do reconcile every Form 1042-S with your general ledger, because reconciliation catches missing foreign tax before the return goes out.
- Do file Schedule K-2 even when in doubt, because the §6698 penalty for filing an unnecessary schedule is zero while the penalty for skipping a required schedule is $245 per shareholder per month.
- Do provide a country-by-country worksheet to each shareholder, because shareholders use the data on Form 1116 and the IRS expects matching numbers.
- Do request reasonable cause abatement under Rev. Proc. 84-35 if the IRS assesses §6698 penalties on a small S corporation, because the procedure still applies to S corporations under post-2017 guidance.
- Don’t rely on prior-year transition relief, because the Notice 2021-39 good-faith standard expired after the 2021 tax year.
- Don’t let a single shareholder request defeat the Domestic Filing Exception silently, because once one shareholder requests a K-3, every shareholder must receive one.
- Don’t ignore Part VI when an S corporation owns a CFC, because GILTI inclusion is automatic regardless of distributions.
- Don’t translate foreign currency using random rates, because §986(a) prescribes specific average and spot rates by tax type.
- Don’t file paper, because the IRS rejected paper Schedule K-2 filings under the Taxpayer First Act e-file mandate.
Pros and Cons of the Domestic Filing Exception
The Domestic Filing Exception is a popular shortcut, but it has trade-offs.
- Pro: It saves preparer time because skipping K-2 and K-3 reduces an average return by two to four billable hours.
- Pro: It protects sensitive ledger detail because the schedule discloses country-by-country expense apportionment that some clients prefer not to share.
- Pro: It reduces shareholder confusion because shareholders without foreign activity do not need to read a 20-page schedule.
- Pro: It aligns with IRS Publication 514 guidance for de minimis foreign tax under $300 on the foreign tax credit without a Form 1116.
- Pro: It still allows the IRS to request the schedule on examination, so the documentation exists in your workpapers either way.
- Con: One shareholder request defeats the exception for everyone and forces a late-season scramble.
- Con: The four-criteria test changes if any shareholder is a non-resident alien, and a single new shareholder mid-year can break the exception.
- Con: The shareholder notice deadline mirrors the K-1 furnishing date, so a late K-1 also breaks the exception.
- Con: Limited foreign tax above $300 voids the exception even when the activity is otherwise tiny.
- Con: Some state returns, including California Form 100S and New York Form CT-3-S, still require K-2-style detail for the state-level Pass-Through Entity Tax election even when the federal exception applies.
Penalty Exposure and Abatement
The headline penalty for an incomplete Form 1120-S is the §6698 penalty at $245 per shareholder per month for up to 12 months. A four-shareholder S corporation that files a complete return without Schedule K-2 faces $11,760 in §6698 exposure.
The plain-English consequence of providing an incomplete Schedule K-3 to a shareholder is the §6722 penalty at $310 per failure for the 2025 tax year, doubled to $620 if the failure is intentional. The §6721 penalty for not filing the K-3 with the IRS adds another $310.
A real-world example involves Daniel Cohen, a CPA who skipped K-2 and K-3 for a client with eight shareholders. The IRS issued a CP162 notice for $23,520 in §6698 penalties plus $2,480 in §6722 penalties, for a total of $26,000 on a single return.
A common misconception is that Rev. Proc. 84-35 covers S corporations the same way it covers partnerships. The IRS clarified in Program Manager Technical Advice 2020-01 that Rev. Proc. 84-35 by its terms applies only to partnerships, although many S corporations win abatement under first-time abate or reasonable cause.
State Conformity Issues
States do not all conform to Schedule K-2. The plain-English consequence is that an S corporation may file a federal Domestic Filing Exception return and still owe a full state K-2 equivalent.
California Form 100S requires Schedule K-1 (100S) detail that mirrors federal Schedule K-3 for shareholders claiming the Pass-Through Entity Tax credit under AB 150. New York Form CT-3-S requires international detail to compute the New York PTET addition.
Texas does not impose a personal income tax but the Texas franchise tax treats foreign source income as part of the apportionment factor, which means an S corporation must still gather the data even when no K-3 is required at the federal level.
Recap of Key Court Rulings and Guidance
The leading court ruling on partnership and S corporation international reporting is Farhy v. Commissioner, a 2023 Tax Court case holding that the IRS lacks statutory authority to assess §6038(b) penalties without a deficiency procedure. The D.C. Circuit reversed Farhy in 2024, restoring IRS assessment authority.
The plain-English consequence is that the IRS can again assess §6038 penalties at $10,000 per missed Form 5471 and $50,000 per continuing failure, and those penalties stack on top of the §6698 and §6722 penalties tied to Schedule K-2.
A common misconception is that Farhy still blocks IRS penalty assessment. The D.C. Circuit decision in Farhy v. Commissioner, No. 23-1179 reversed the Tax Court and the IRS now enforces the penalties under standard assessment procedures.
FAQs
Does every S corporation have to file Schedule K-2?
No. An S corporation that meets all four Domestic Filing Exception criteria may skip Schedule K-2 and Schedule K-3. The exception requires no foreign activity, only eligible U.S. shareholders, timely shareholder notice, and no shareholder K-3 request.
Is the Schedule K-2 deadline the same as Form 1120-S?
Yes. Schedule K-2 e-files with Form 1120-S by March 15 for calendar-year S corporations. A six-month extension on Form 7004 carries the K-2 to September 15.
Can I paper-file Schedule K-2?
No. The IRS Modernized e-File mandate under the Taxpayer First Act forces e-filing for almost every S corporation, and paper Schedule K-2 attachments are rejected at intake.
Does $200 of foreign tax trigger Schedule K-2?
No. Foreign tax under $300 qualifies as limited foreign activity and preserves the Domestic Filing Exception when all other criteria are met. The income must come from a qualified payee statement.
Will the IRS waive penalties for a first-time mistake?
Yes. First-time abate relief is available for an S corporation with a clean three-year compliance history, and the IRS routinely grants the waiver on the first §6698 assessment tied to Schedule K-2.
Must Schedule K-3 reach shareholders by March 15?
Yes. The K-3 furnishing deadline matches the K-1 deadline. Late K-3 delivery exposes the S corporation to §6722 penalties at $310 per failure for the 2025 tax year.
Can a non-resident alien own S corporation stock through Schedule K-2 disclosure?
No. §1361(b)(1)(C) bars non-resident alien shareholders, and Schedule K-2 disclosure does not cure the S election violation. The election terminates on the day the non-resident alien acquires stock.
Does Schedule K-2 replace Form 5471?
No. Form 5471 still applies to U.S. shareholders of controlled foreign corporations. Schedule K-2 supplements Form 5471 by allocating CFC items to each shareholder.
Are state K-2 equivalents required?
Yes. California, New York, and several other states require K-2-style detail for Pass-Through Entity Tax elections even when the federal Domestic Filing Exception applies.
Can I amend Schedule K-2 after filing?
Yes. File a superseded or amended Form 1120-S with corrected K-2 and K-3 attachments. Issue corrected K-3s to shareholders so they can amend their personal returns within the §6511 refund window.
Does the Domestic Filing Exception apply if one shareholder is a single-member LLC?
Yes. A single-member LLC owned by a U.S. citizen or resident is treated as a disregarded entity, and the underlying U.S. owner counts as the eligible shareholder.
Are foreign mutual funds always PFICs?
Yes. Most foreign mutual funds, UCITS, and SICAVs meet the §1297 income or asset test and trigger PFIC reporting on Schedule K-2 Part VII.
