What Form 8865 2018 Is For
IRS Form 8865 (2018) is used by the Internal Revenue Service to collect information from U.S. persons who hold foreign partnership interests. It provides the IRS with details about ownership structures, proportional interest, transactions, and reporting obligations involving certain foreign partnerships. The form supports international tax compliance by ensuring that partnership income, property contributions, and foreign-sourced income are disclosed adequately on a taxpayer’s annual income tax return.
U.S. taxpayers must file Form 8865 when they meet specified ownership thresholds, contribute property to a foreign partnership, or experience reportable events involving a partnership's tax year. The filing requirement applies to individuals, corporations, partnerships, trusts, and exempt organization returns that have a filing obligation involving foreign entities.
When You’d Use Form 8865
A U.S. person is required to file Form 8865 when they satisfy one of the four filing categories established by the IRS. Each filing category determines the applicable schedules and the extent of reporting relating to foreign partnerships.
A taxpayer may need to file Form 8865 in the following situations:
- A U.S. person controls a controlled foreign partnership during the tax year.
- A U.S. person owns at least a 10 percent partnership interest, while U.S. persons collectively own more than 50 percent of the partnership interest.
- A taxpayer contributes property to a foreign partnership and meets the fair market value or contributed property thresholds.
- A U.S. person has a reportable event involving acquisitions, dispositions, or changes in foreign partnership interests.
Form 8865 is attached to the federal income tax return or annual tax return. When a taxpayer files late, they must submit the form as soon as possible to reduce significant penalties. When filing an amended return, the taxpayer must update Form 8865 and include all applicable schedules to correct inaccurate or incomplete information.
Key Rules or Details for 2018
The 2018 tax year included several updates affecting international tax obligations and reporting obligations for foreign partnerships. These changes impacted how taxpayers reported foreign partnership income, foreign taxes, and ownership thresholds.
Essential rules for 2018 include:
- The Tax Cuts and Jobs Act introduced new international tax compliance rules for foreign sources of income and partnership income.
- The gain deferral method under Section 721(c) required additional schedules when a taxpayer chose to contribute property to a foreign partnership.
- Global intangible low-taxed income rules affected the reporting of foreign tax credits and gross income from foreign partnerships.
- Constructive ownership rules remained essential for determining ownership percentages and whether a taxpayer was required to file Form 8865.
- The IRS clarified how to determine the partnership's tax year when multiple taxpayers file Form 8865 with respect to the same foreign corporation.
Taxpayers needed to review filing requirements carefully to ensure accurate reporting of ownership structure, reportable events, related entities, and foreign partnership schedules.
Step-by-Step (High Level)
Step 1: Determine the Filing Category
A taxpayer must evaluate which filing category applies based on ownership thresholds, reportable events, and involvement with foreign partnerships. This step determines the applicable schedules for filing Form 8865.
Step 2: Gather Partnership Documents
A taxpayer should collect all necessary partnership documents, including balance sheets, income statements, business income schedules, partnership interest schedules, and related entities schedules. These documents support accurate reporting of partnership income and the partner’s share of gross income.
Step 3: Review Ownership and Constructive Ownership Rules
The IRS evaluates both direct ownership and constructive ownership when determining whether a U.S. person is required to file Form 8865. Constructive ownership includes interests held by family members or other related entities.
Step 4: Complete the Required Schedules
A taxpayer must complete all schedules required for the filing category. These schedules may include:
- Schedule A for ownership percentages
- Schedule B for income statement reporting and business income details
- Schedule K and Schedule K-1 for allocations of partnership income
- Schedule L for balance sheets and financial information
- Schedule M for reconciliation of financial accounts
- Schedule G or H for reporting property contributions under the gain deferral method
Each schedule must be completed accurately to avoid costly mistakes and prevent unintentional disregard of filing requirements.
Step 5: Attach Form 8865 to the Tax Return
A taxpayer must attach Form 8865 to their federal income tax return, annual tax return, or amended income tax return. The form is not submitted separately. Filing deadlines correspond to the deadlines for the tax return, including extensions.
Step 6: Verify Accuracy Before Filing
A taxpayer should check foreign taxes, fair market value calculations, ownership percentages, proportional interest, and reportable events to ensure accuracy. Accurate reporting reduces the number of IRS notices associated with false or fraudulent information.

Common Mistakes and How to Avoid Them
- Filing the wrong category or missing schedules: Review all four Form 8865 filing categories and attach every schedule required for your category before submitting.
- Failing to apply constructive ownership rules: Identify ownership held through family members or related entities to ensure the filing obligation is correctly triggered.
- Providing incomplete property contribution details: Report all contributed property and include fair market value, dates, and required descriptions to avoid missing Category 3 disclosures.
- Reporting incorrect fair market value or proportional interest: Verify valuation methods and ownership percentages with reliable documentation before filing.
- Relying on foreign partnerships or foreign entities without verification: Confirm all figures and partnership activity independently, as the U.S. taxpayer—not the foreign entity—is responsible for accurate Form 8865 reporting.

What Happens After You File
Once Form 8865 is filed with the federal income tax return, the IRS processes the information together with the taxpayer’s other filings. The IRS uses partnership details to verify partnership income, foreign tax credits, foreign taxes, and the taxpayer’s tax liability.
The IRS may take the following actions:
- Match partnership statements with information provided by foreign persons, foreign entities, or foreign corporations.
- Review the ownership structure and constructive ownership details to confirm the filing obligation.
- Issue an IRS notice if information is missing, inaccurate, or inconsistent.
- Investigate issues involving partnership income, fair market value reporting, or foreign sources of revenue.
Submitting complete and accurate information reduces risks associated with intentional disregard, false or fraudulent information, or extended review periods.
