For partnerships with foreign partners, filing Form 8804 is an essential responsibility. This form, known as the Annual Return for Partnership Withholding Tax (Section 1446), is used to report the withholding tax on effectively connected taxable income allocable to foreign partners. Whether you’re managing your payroll taxes internally or relying on professional assistance, understanding how to complete Form 8804 accurately is critical. In this guide, we provide a step-by-step walkthrough of how to file Form 8804, along with tips to simplify the process using expert tax services.
What is Form 8804?
Form 8804 is the official IRS document used by partnerships to report withholding tax on income allocable to foreign partners under Section 1446. In other words, if your partnership has foreign partners, you must calculate and report the tax withheld on their share of the effectively connected taxable income. This form summarizes the total amount of tax deposited for the quarter and determines the amount of withholding tax due. Properly completing Form 8804 is crucial for ensuring that your partnership remains compliant with IRS regulations and avoids any potential penalties.

Who Must File Form 8804?
Filing Form 8804 is required for partnerships that have one or more foreign partners who are subject to withholding under Section 1446. Generally, if your partnership has foreign owners or allocates a share of income to nonresident aliens, you will need to file this form. The IRS uses the information provided on Form 8804 to verify that the correct tax has been withheld and deposited. If you are unsure whether your partnership meets these criteria, review the Form 8804 instructions or consult with a professional tax service for clarification.
Why Accurate Filing of Form 8804 is Important
Accurate and timely filing of Form 8804 ensures that your partnership:
- Meets IRS compliance requirements: Avoid potential fines or penalties for under-withholding or late filings.
- Properly allocates withholding tax: Ensures that foreign partners receive the correct credit on their U.S. tax returns.
- Maintains clear records: Helps create an audit trail that supports your filings and tax payments.
- Facilitates international transactions: Proper certification and reporting make it easier for foreign partners to claim tax treaty benefits and avoid double taxation.
Taking the time to file Form 8804 correctly can help maintain smooth business operations and strengthen your partnership’s financial integrity.
Step-by-Step Instructions for Completing Form 8804
Follow the detailed steps below to file Form 8804 accurately. Each step is designed to guide you through the process from start to finish.
Step 1: Gather the Necessary Information
Before beginning, collect all the required documents and details:
- Partnership Information: Legal name, Employer Identification Number (EIN), and the principal business address.
- Foreign Partner Data: Names, addresses, and tax identification numbers (if applicable) for each foreign partner.
- Financial Records: A detailed breakdown of the partnership’s effectively connected taxable income (ECTI) for the period and the corresponding amounts allocated to foreign partners.
- Deposit Records: Documentation of the tax deposits made during the quarter, including bank statements or payroll system reports.
Having these documents ready will simplify the filing process and reduce the risk of errors.
Step 2: Complete the Identification Section
Begin filling out Form 8804 by entering the basic identification details:
- Line 1: Enter the legal name of your partnership precisely as it appears on your formation documents.
- Line 2: Provide your partnership’s EIN.
- Line 3: Enter the partnership’s mailing address. Ensure this address matches what the IRS has on record.
- Line 4: If applicable, include any “doing business as” (DBA) names.
Double-check this information to avoid any discrepancies that could delay processing.

Step 3: Specify the Tax Period
In this section, indicate the tax period for which you are filing the return:
- Line 5: Enter the beginning and ending dates of the quarter you are reporting on (e.g., January 1 to March 31 for Q1). Use the correct format as specified in the instructions for Form 8804.
- Line 6: Confirm whether the period reported is for a calendar quarter or a fiscal quarter.
Accurately specifying the tax period is critical for ensuring that the IRS can match your withholding tax deposits to the correct reporting period.
Step 4: Report the Total Withholding Tax
This is the heart of Form 8804, where you summarize the withholding tax:
- Line 7: Enter the total amount of tax withheld on the foreign partners’ shares of the effectively connected taxable income. This amount should be the sum of all the deposits made for the quarter.
- Line 8: Provide a breakdown of the tax withheld by reporting the amounts deposited on the applicable dates. If the form requires further details, use the supplemental schedule provided with the instructions for Form 8804.
Using accurate figures here is essential, as any misreporting could lead to penalties or delayed refunds for your foreign partners.
Step 5: Calculate the Total Tax Liability
Next, determine the total tax liability that is due:
- Line 9: Based on the partnership’s taxable income and the applicable withholding tax rates under Section 1446, calculate the total tax liability for the period.
- Line 10: Subtract the total tax deposits (reported on Line 7) from the calculated tax liability. This will show whether additional tax is due or if you have an overpayment.
Ensure all calculations are double-checked and that they reconcile with your financial records.
Step 6: Provide Additional Information
The form may require supplementary details regarding your foreign partners:
- Line 11: If applicable, list any adjustments or corrections that were made during the quarter.
- Line 12: Attach any additional schedules or documentation as required by the instructions on Form 8804 to support your calculations.
These additional details help the IRS verify your reported amounts and confirm that all foreign partners’ allocations are correct.
Step 7: Review, Sign, and Date the Form
Before submission, carefully review the completed Form 8804:
- Double-Check All Entries: Verify that every line is accurately filled out and that all figures match your supporting documents.
- Sign and Date: If you are filing a paper return, sign and date the form in the designated area. For electronic filings, follow the IRS guidelines for digital signatures.
- Prepare Attachments: Ensure that any required schedules or supporting documentation are attached.
A meticulous review of your form will help avoid potential processing delays or IRS queries.
Step 8: Submit Form 8804
The final step is submitting your completed form:
- Electronic Filing: Many partnerships prefer e-filing through the IRS’s online system, which generally speeds up processing times.
- Mailing: If you opt for a paper filing, send your Form 8804 to the IRS address provided in the current instructions. It’s advisable to use certified mail or another method that includes delivery confirmation.
- Keep Records: Retain a copy of the completed form and all supporting documents for your records. These may be necessary for future audits or correspondence with the IRS.
Following the correct submission procedures ensures that your form is processed without issues and that your partnership remains in compliance.
