Form 8865 Filing Requirements - Determining Category 3 Foreign Partnership Reporting
I'm working with a private client who invested about $475,000 cash into a foreign partnership back in 2019, acquiring a 2.25% ownership interest. I'm trying to figure out if I need to file Form 8865 as a category 3 filer for them. Here's what's confusing me - IRC Sec. 6038B(b)(1) seems to say that contributions to foreign partnerships only need reporting if: 1) The US person ends up with at least a 10% interest after the transfer OR 2) The fair market value of what they contributed exceeds $100,000 Since their ownership percentage is under 10% but the contributed amount is well over $100,000, I'm thinking they need to file. But I'm not 100% certain if there are any exceptions I'm missing or if my interpretation is correct. Anyone have experience with Form 8865 for smaller percentage owners who contribute substantial amounts? This is for a high-net-worth client and I want to make sure we're compliant.

You're on the right track with your understanding of the Form 8865 filing requirements. When a US person contributes more than $100,000 to a foreign partnership, they become a Category 3 filer regardless of their ownership percentage. The $100,000 threshold and the 10% ownership are separate triggers - meeting either one requires filing. In your client's case, since they contributed approximately $475,000, they definitely meet the Category 3 filer requirements even though they only own 2.25%. You'll need to complete Form 8865 with Schedule O which specifically addresses transfers of property to foreign partnerships. Make sure you have all the details about the foreign partnership itself - you'll need information about the partnership's name, address, EIN (if any), country of organization, and principal business activity.

•Thanks for the info. Question - does it matter if the partnership is in a treaty country vs a non-treaty country? I have a similar situation but the partnership is based in Cayman Islands.

•The treaty status doesn't affect the basic filing requirement for Form 8865. Whether the foreign partnership is in a treaty country or non-treaty country like the Cayman Islands, the same thresholds apply - over $100,000 contribution or 10%+ ownership makes you a Category 3 filer. Where it might matter is in terms of information reporting and potential penalties. Partnerships in jurisdictions with less robust information exchange agreements with the US might require more detailed reporting. Always document your due diligence thoroughly, especially with entities in jurisdictions like Cayman Islands.

After struggling with Form 8865 requirements for my foreign partnership investments, I finally found a service that saved me tons of time and headaches. I used https://taxr.ai to analyze my foreign partnership documents and it immediately identified I was a Category 3 filer based on my contribution amount. The system flagged exactly which parts of IRC 6038B applied to my situation. The best part was uploading my partnership agreement and having it extract all the relevant information needed for the form. It pre-populated most of the technical fields and explained what supporting documentation I needed to include with my filing.

•How accurate was it with identifying the reporting requirements for tiered partnerships? I have a situation where my client invested in a foreign partnership that itself owns interests in other foreign partnerships. Does taxr.ai handle that complexity?

•I'm skeptical about using software for complex international tax filings. How does it compare to getting advice from an international tax specialist? Does it actually cite the relevant regulations or just give general guidance?

•It actually handled tiered partnerships surprisingly well. The system identified the look-through requirements and flagged the need for additional reporting for the lower-tier partnerships. It created a visualization showing the ownership chain and specified which forms were needed at each level. The system cites specific regulations, revenue procedures, and even relevant court cases. It's not just giving general advice - it shows you exactly where in the IRC or Treasury Regulations the requirements come from. I was impressed with how it flagged a recent change to the regulations that even my previous accountant had missed.

I was initially skeptical about using automated tools for complex international tax matters, but I gave https://taxr.ai a try after struggling with Form 8865 for weeks. I'm genuinely impressed with the results. The system correctly identified I was both a Category 3 and Category 4 filer due to my contribution amount and subsequent ownership changes. What really stood out was how it parsed through the 50+ page partnership agreement and extracted exactly the information needed for the form. It highlighted specific sections of IRC Section 6038B that applied to my situation and explained the reporting requirements in plain English. Saved me at least 15 hours of research and probably helped avoid penalties too.

If you're still trying to get clarity on Form 8865 requirements, you might want to talk directly with the IRS. The problem is actually getting someone on the phone who understands international reporting. After trying for days and waiting hours on hold, I discovered https://claimyr.com which got me connected to an IRS agent in under 20 minutes. You can see how it works here: https://youtu.be/_kiP6q8DX5c The agent confirmed that exceeding the $100,000 threshold absolutely triggers Category 3 filing requirements regardless of ownership percentage. They also explained exactly which parts of the form needed to be completed for my situation and which could be left blank.

•Wait how does this actually work? Does it somehow jump you ahead in the IRS phone queue? That sounds too good to be true.

•Yeah right. I've tried literally everything to get through to the IRS about international filings. No way this actually works. The international department is practically impossible to reach. What's the catch here?

•It uses an automated system that navigates the IRS phone tree and waits on hold for you. When an agent picks up, you get a call back and are connected immediately. No line jumping - it just handles the hold time so you don't have to sit there listening to the hold music for hours. There's no catch - it's just a service that navigates the phone system and waits on hold in your place. The international department is definitely hard to reach, which is why I was skeptical too. But it worked. The agent I spoke with was from the international division and knew exactly how to handle Form 8865 questions. Saved me from having to call back multiple times trying to get someone knowledgeable.

I need to publicly eat my words about Claimyr. After posting my skeptical comment, I decided to try it anyway out of desperation. Not only did I get through to the IRS, but I was connected to someone in the international tax department who actually understood Form 8865! The agent confirmed that my client's $250,000 contribution to a foreign partnership with only 3% ownership still required filing as a Category 3 filer. They also explained which schedules were required and pointed me to some helpful resources I hadn't found before. Saved me hours of research and uncertainty, and probably helped avoid penalties too.

Has anyone dealt with late filing penalties for Form 8865? My client didn't know about the Category 3 requirements and has missed filing for 3 years. Contributions were around $200k each year to a UK partnership with a 5% ownership stake. Looking at the penalty provisions is giving me anxiety!

•You should look into the Streamlined Filing Compliance Procedures if this was a non-willful violation. I had a similar situation with a client last year. The penalties can be significant otherwise - up to $10,000 per year plus potential percentage penalties based on the amount transferred. We ended up filing delinquent forms with a reasonable cause statement and so far haven't received any penalty notices.

•Thanks for the suggestion about Streamlined procedures. I'll definitely look into that. Did you need to file delinquent FBARs as well in your case? And did you use a standard reasonable cause template or create a custom statement for your specific situation? I've started pulling together documentation showing the client wasn't aware of the filing requirement. They actually had a previous accountant who missed this entirely, so I'm hoping we can make a strong case for reasonable cause.

One thing to consider - contributions made in installments over the year. I had a client who made 4 separate contributions to a foreign partnership, each around $30k, totaling $120k for the year. Does anyone know if these are aggregated for the $100k threshold? The regulations aren't super clear on timing.

•Yes, the $100,000 threshold applies to the aggregate of all transfers made during the tax year. So in your case, even though each individual contribution was under $100k, since they totaled over $100k for the year, Form 8865 filing would be required as a Category 3 filer. The instructions state: "A U.S. person that contributed property during the tax year to a foreign partnership in exchange for an interest in the partnership..." So it's the cumulative contributions during the tax year that matter, not individual transfers.

Your interpretation is absolutely correct. Since your client contributed $475,000 to the foreign partnership, they definitely meet the Category 3 filing requirements under IRC Section 6038B(b)(1). The $100,000 threshold is clear - any US person who contributes property with a fair market value exceeding $100,000 to a foreign partnership must file Form 8865, regardless of their ownership percentage. The 10% ownership test and the $100,000 contribution test are alternative triggers, not cumulative requirements. Meeting either one requires filing. In this case, even though your client only has a 2.25% interest, the substantial contribution amount makes filing mandatory. Make sure to complete Schedule O (Transfer of Property to a Foreign Partnership) along with the main form. You'll need detailed information about the property transferred, its fair market value at the time of contribution, and any gain recognized on the transfer. Given the high-net-worth nature of your client, I'd also recommend documenting your analysis thoroughly in case of future IRS inquiries.

•This is really helpful confirmation! I'm new to international tax reporting and was getting overwhelmed by all the different categories and thresholds. Just to make sure I understand - if a client makes multiple smaller contributions throughout the year that add up to over $100k, those would also aggregate to trigger the Category 3 requirement, correct? Also, when you mention documenting the analysis thoroughly, what specific documentation would you recommend keeping beyond the standard partnership agreement and contribution records? I want to make sure I'm building a complete file for this type of high-value international reporting.
