What is Form 8865?
IRS Form 8865 tracks foreign partnerships with significant US ownership or control. If you’re a US person involved in such partnerships, you may need to file it with your tax return.
The form ensures proper disclosure of foreign business interests that affect your tax liability, including acquiring or disposing of partnership interests, controlling the partnership, or contributing assets.

Who needs to file tax Form 8865?
The IRS has defined four categories of this form filers, each with specific filing triggers.
| Form 8865 filer category | Who must file – filing requirement | Trigger event |
|---|---|---|
| Category 1: Control of a foreign partnership | US person who controlled the foreign partnership at any time during the tax year. | Control of more than 50% of the partnership’s capital or profit interests, directly or indirectly. |
| Category 2: 10% or more interest in a controlled foreign partnership | US person who owns at least 10% of a foreign partnership while US persons collectively control more than 50%. | Ownership of at least 10%, with US group control exceeding 50%. |
| Category 3: Contributions to a foreign partnership | US person who contributed property to a foreign partnership and either: (a) owns at least 10% after the transfer, or (b) contributed over $100,000 within a 12-month period. | Transfer of property meeting the ownership or value threshold. |
| Category 4: Reportable transactions (acquisition, disposition, or ownership changes) | US person involved in reportable events such as acquiring or disposing of a partnership interest, or ownership changes affecting their share. | Filing is required if you acquired or disposed of a 10% or greater interest, or if there was a change in ownership structure affecting your interest. |
Each filer category requires different schedules and disclosures, so it’s critical to determine your category before filing.

Form 8865 requires US taxpayers to report extensive information about foreign partnerships. Below is a breakdown of the main schedules and what each requires:
Schedule A – Ownership of the foreign partnership
Details each US filer’s ownership in the partnership, including direct, indirect, and constructive ownership. This section tracks who owns what and helps the IRS identify control and reporting obligations.
Schedule B – Income statement and balance sheet information
Reports the partnership’s financials:
- profit and loss statement: total income, expenses, and net profit or loss
- balance sheet: assets, liabilities, and partners’ equity at both the beginning and end of the year
- statement of cash flows: optional, but adds insight into cash movement
Schedule G – Partner transactions
Captures all transactions between the filer and the foreign partnership, including capital contributions and distributions, intercompany transactions (e.g., loans or services), and transfer pricing disclosures, if applicable.
Schedule K-1 equivalent – Partner’s share of income and deductions
Details how income, deductions, and credits are allocated to each partner. It also includes:
- ownership percentages and any changes during the year
- capital account activity and end-of-year balance
- partner identifying details (name, TIN, and address)
