What is a foreign partnership?
A foreign partnership is generally an entity formed outside the US that the IRS treats as a partnership under U.S. tax rules (not local law). This depends on US entity classification rules, not just how the business is treated abroad.. It doesnโt matter where in the world you live or whether your business pays local taxes: if you’re an US citizen or Green Card holder with an ownership stake in a foreign partnership, including startups, investment funds, joint ventures, or family businesses abroad, youโll need to report it. If income, losses, or assets flow through the entity to its partners, itโs likely a partnership and you may need to report it on Form 8865.
How should expats report a foreign partnership?
You report a foreign partnership by filing Form 8865 with your annual US tax return. The form includes details about the partnershipโs structure, financials, income, and your ownership percentage. Which parts you need to complete depends on how much control or interest you have. Youโll also report any transfers of property, changes in ownership, or significant transactions.
Why Form 8865 matters
Form 8865 lets the IRS know about your overseas business interests and helps them ensure you’re complying with tax laws, even if no direct tax is due.
Even if no tax is due, you have to report the activity, ownership, and financial details of your foreign partnership. Ignoring it or filing it late can trigger serious penalties.
Exactly which expats have to file Form 8865?
Not every expat has to file Form 8865. The IRS divides filers into four categories:
- Category 1: You control the foreign partnership (meaning you directly or indirectly own more than 50% of it).
- Category 2: You own at least 10%, and US persons collectively control the partnership (but no single one owns more than 50%).
- Category 3: You transferred property to a foreign partnership. You either got at least a 10% stake from that transfer, or the total value of your transfers was over $100,000 in a 12-month period.
- Category 4:ย You had a reportable acquisition, disposition, or change in proportional interest in the foreign partnership, generally when your ownership percentage increases or decreases by at least 10% or crosses the 10%, 50%, or other ownership thresholds set by the IRS..
If youโre not sure whether you qualify, seek advice. Many expats miss their foreign partnership filing requirement because they assume their involvement is too small to matter when often it isnโt.
Which schedules should you complete?
Form 8865 isnโt one-size-fits-all. The form contains multiple sections and schedules, and which ones you need depends on your filing category.
When it comes to reporting foreign partnerships as an American abroad, always seek assistance from an expat tax expert, but hereโs a general guide as to whatโs required:
Schedules Most Filers Must Include
- Page 1: Basic identifying information.
- Schedule A: Shows your direct and indirect ownership in the partnership.
- Schedule A-3: Lists any foreign affiliates of the partnership.
Additional Schedules By Category
- Category 1 (Control Owners): The most extensive. Youโll need Schedules A-1, B, G, H, K, K-1, K-2, K-3, L, M-1, M-2, N, D, and O.
- Category 2: Requires fewer forms, but still includes A, A-3, K-1, and part of N.
- Category 3 (Property Contributors): You’ll need A, A-1 (unless you only contributed cash), G, H, and Schedule O.
- Category 4 (Changes in Ownership): Must complete A, A-3, G, H, P, and potentially others if gain deferral is involved.
Beginning with 2021 tax years (returns filed in 2022), the IRS introduced Schedules K-2 and K-3 for partnerships with international tax items. These are required if the partnership has income, deductions, credits, or other items relevant to international reporting. These schedules break down each partnerโs share of income, deductions, and credits, and provide detailed international information.
If your partnership has any international touchpoints, you’re likely filing these schedules too.
What are the deadlines for filing Form 8865?
Form 8865 is due with your personal tax return, which is normally April 15. Expats get an automatic extension to June 15, but note that interest on any tax due still accrues from April 15. With Form 4868, you can extend filing (not payment) to October 15. Even though itโs an informational return, treat the deadlines seriously. A late Form 8865 can result in heavy penalties, even if your tax return is otherwise complete and on time.
Attach Form 8865 to your personal tax return if youโre filing by mail. If youโre e-filing, the software should include Form 8865 as part of your return submission. Make sure it does.
What are the penalties for not filing Form 8865?
The penalties for missing or incorrectly filing Form 8865 can escalate quickly.
- Base penalty: $10,000 per year, per foreign partnership, per category.
- Extended delay: If you fail to file after 90 days of IRS notification, youโll owe an additional $10,000 for every 30 days itโs late, up to $50,000 total.
- Loss of tax benefits: You could lose your foreign tax credits or be denied deductions related to the partnership.
- Category 3 filers: An additional penalty equal to 10% of the fair market value of the transferred property, capped at $100,000โunless the IRS decides you willfully disregarded the rules. Then the cap is removed.
- Audit risk: Failure to file Form 8865 keeps the statute of limitations open on your entire tax return, meaning the IRS can audit those years indefinitely until the form is filed.
In other words, the IRS doesnโt take reporting foreign partnerships lightly, and neither should you.
If youโve missed filing in previous years as an expat, you may be able to file a late or amended return or you may be able to file under the IRS Streamlined Foreign Offshore Procedures to reduce or avoid penalties, depending on your situation.
Practical tips for expats
Many US expats involved in foreign businesses arenโt aware that they may have to file Form 8865. Here are some tips to ensure you donโt unknowingly get caught out:
- Think about ownership: If you own more than 10% of a foreign partnership or are involved in forming or contributing to one, assume you may need to file and seek advice.
- Review any business transfers: If you contributed assets, especially intellectual property, equipment, or cash, you could trigger Category 3.
- Coordinate with other US partners, as you might fall under Category 2 if US persons collectively control the partnership.
- Use Form 5471 as a reference point: If you’re already filing for a foreign corporation, you might also have a partnership interest, as the IRS often ties these forms together.
- Donโt underestimate complexity. Hiring a qualified expat tax advisor may save you far more than what they cost. Most standard CPAs wonโt be familiar with Form 8865.
- Keep detailed records, especially of contributions, ownership percentages, and business activity.
- Donโt wait until tax season. Knowing whether you need to file Form 8865 often takes time to work out, and the earlier you prepare, the smoother the filing.
Reporting foreign partnerships isnโt simple
Form 8865 is one of the most complex informational returns required of US expats. Itโs also one of the easiest to overlook. Whether youโre running a company overseas, investing in one, or transferring property into a foreign partnership, you may have a filing obligation.
What matters most is that you donโt delay. Form 8865 carries high penalties, strict deadlines, and deep disclosure requirements, but with early action and the right strategy, you can stay compliant without stress.
If youโre unsure whether you need to file, scheduling a conversation with an expat tax expert can save you thousands later. When it comes to foreign partnerships, itโs better to be over-prepared than sit back until the IRS contacts you.
