Introduction: What is IRS Form 8805?
IRS Form 8805, titled Foreign Partner’s Information Statement of Section 1446 Withholding Tax, is an official international tax reporting statement administered by the Internal Revenue Service (IRS) under the Department of the Treasury. It is governed by Internal Revenue Code (IRC) Section 1446 and Treasury Regulations § 1.1446-1 through § 1.1446-7.
While Form 8804 serves as the master annual tax return filed by the partnership, Form 8805 is the individual payee statement prepared for each foreign partner. Similar to how a Form W-2 reports wage withholding for an employee, Form 8805 reports the exact amount of Effectively Connected Taxable Income (ECTI) allocated to a foreign partner and the specific dollar amount of federal withholding tax paid on their behalf.
Purpose of the Form: Why Form 8805 Exists
Under Section 1446, partnerships operating an active trade or business in the United States are legally required to withhold federal income tax on U.S. business profits allocable to foreign partners. Because this withholding tax is remitted as an estimated prepayment toward the partner’s final U.S. tax bill, foreign partners need official documentation to prove that the tax was paid.
Form 8805 solves this reporting need. It provides the foreign partner with an official, verifiable tax document that must be attached to their annual U.S. tax return (such as Form 1040-NR or Form 1120-F). This allows the foreign partner to claim a dollar-for-dollar tax credit and receive a direct refund from the IRS if the partnership over-withheld tax during the year.
Understanding the Multi-Copy System of Form 8805
Form 8805 is produced as a multi-part document with specific distribution rules for each copy:
| Copy Designation | Recipient / Destination | Purpose & Action Required |
|---|---|---|
| Copy A | Internal Revenue Service (IRS) | Attached directly to the master return (Form 8804) and mailed to the IRS by the partnership. |
| Copy B | Foreign Partner | Delivered to the foreign partner, who must attach it to their U.S. tax return (Form 1040-NR or Form 1120-F) to claim their withholding credit. |
| Copy C | Foreign Partner | Retained by the foreign partner for their permanent personal financial and tax records. |
| Copy D | Partnership | Retained by the partnership in its permanent business and accounting files. |
Who Needs to File and Receive This Form?
Form 8805 involves two distinct parties with specific legal responsibilities:
- The Partnership Prepares and Files It: Any domestic or foreign partnership (or Multi-Member LLC taxed as a partnership) with Effectively Connected Taxable Income allocable to a foreign partner must complete a separate Form 8805 for every foreign partner.
- The Foreign Partner Receives and Claims It: Nonresident alien individuals, foreign corporations, foreign partnerships, and foreign trusts/estates that receive Copy B must attach it to their annual federal income tax returns to receive credit for the tax paid.
Who Is Exempt / Not Required to Receive Form 8805?
A partnership does not prepare Form 8805 for an owner in the following situations:
- Domestic U.S. Partners: Partners who are U.S. citizens, green card holders, or domestic U.S. corporations (verified via Form W-9).
- Zero Effectively Connected Income: Partnerships that had zero U.S. business income or operated at a net tax loss for the year (unless estimated payments were made on Form 8813 that must be reconciled).
- Purely Passive FDAP Income: Foreign partners who receive only passive U.S.-source investment income (such as dividends or interest), which is reported on Form 1042-S instead.
- Publicly Traded Partnerships (PTPs): Publicly traded partnerships that do not use Section 1446(a) entity withholding (PTPs follow distribution withholding rules reported on Form 1042-S).
When to File: Deadlines and Furnishing Dates
Form 8805 is an annual tax schedule governed by statutory filing deadlines under Treasury Regulation § 1.1446-3:
- Deadline for Filing Copy A with the IRS: The partnership must attach Copy A to Form 8804 on or before the 15th day of the 3rd month following the close of the partnership’s tax year (typically March 15 for calendar-year partnerships, or September 15 if a 6-month extension is filed on Form 7004).
- Deadline for Furnishing Copies B & C to Partners: The partnership must furnish Copies B and C to the foreign partner on or before the due date (including extensions) of Form 8804.
- Foreign Partner Tax Return Deadline: The foreign partner attaches Copy B to their annual tax return (due June 15 for nonresident individuals with no W-2 wages, or April 15 for foreign corporations/individuals with U.S. payroll).
Where and How to File Form 8805
Form 8805 is filed directly with the IRS and distributed to foreign partners as follows:
- Submitting Copy A to the IRS: The partnership attaches Copy A of Form 8805 for every foreign partner directly behind Form 8804 and mails the complete package to the IRS address as per instructions for Section 1446 returns in Ogden, Utah.
- Delivering Copy B & C to Foreign Partners: The partnership sends Copies B and C to each foreign partner via secure electronic transmission or physical mail.
- Foreign Partner Submission: The foreign partner attaches Copy B to Form 1040-NR (for individuals), Form 1120-F (for corporations), or Form 1041 (for foreign estates/trusts) and mails or e-files it with their regular tax return.
Step-by-Step Instructions to Fill Out Form 8805
A separate Form 8805 must be prepared for each foreign partner. Complete each line using the guidelines below:
| Line / Box | Field Description | Instructions |
|---|---|---|
| Box 1a – 1e | Foreign Partner Information | Enter the foreign partner’s full legal name, U.S. Taxpayer Identification Number (SSN, ITIN, or EIN), foreign address, country code, and entity classification (individual, corporation, partnership, trust). |
| Box 2a – 2c | Partnership Information | Enter the partnership’s legal business name, Employer Identification Number (EIN), and physical mailing address. |
| Line 8 | Total Allocable ECTI | Enter the foreign partner’s total share of Effectively Connected Taxable Income for the year before character breakdowns. |
| Line 9a – 9d | Character Breakdown of ECTI | Itemize the partner’s share of ECTI by tax category: ordinary income, 28% rate gains, unrecaptured Section 1250 gains (25%), and qualified dividends / net long-term capital gains (20%). |
| Line 10 | Total Section 1446 Withholding Tax | Enter the total dollar amount of federal withholding tax paid on this partner’s behalf (calculated at 37% for non-corporate partners, 21% for corporate partners, or preferential capital gain rates). |
The Critical Importance of the Foreign Partner’s U.S. TIN
One of the most vital fields on Form 8805 is Box 1b (Foreign Partner’s U.S. TIN):
- The foreign partner must have a valid U.S. Social Security Number (SSN), Individual Taxpayer Identification Number (ITIN), or Employer Identification Number (EIN).
- If Box 1b is left blank or marked “applied for,” the IRS will accept the partnership’s money but will not credit the tax payment to the foreign partner’s account.
- Without a verified TIN on Form 8805, the foreign partner cannot claim their withholding credit on Form 1040-NR or Form 1120-F, resulting in frozen tax refunds that can take years to resolve.
Required Documents and Information Needed Before Filling
Before completing Form 8805 for your foreign partners, assemble the following records:
- Schedule K-1 (Form 1065): The completed Schedule K-1 detailing the partner’s distributive share of ordinary income, capital gains, and deductions.
- Form W-8 Series: Valid, active Forms W-8BEN, W-8BEN-E, or W-8ECI on file for each foreign partner confirming their legal foreign address, country code, and U.S. TIN.
- Form 8804-C (if applicable): Any certified partner-level loss certificates submitted by the foreign partner to reduce their withholding base.
- Form 8804 Worksheets: The master calculation sheets reconciling total ECTI and total tax withholding across all partners.
Common Mistakes to Avoid
- Submitting Blank Partner TINs: Leaving Box 1b blank. Always require foreign partners to complete Form W-7 (ITIN) or Form SS-4 (EIN) upon joining the partnership.
- Mismatched Totals with Form 8804: The sum of all Lines 10 across all Forms 8805 must match the total withholding tax reported on the partnership’s master Form 8804, Line 5 exactly.
- Applying Wrong Tax Rates: Calculating 21% withholding for a foreign individual (individuals must be withheld at 37%) or 37% for a foreign corporation.
- Failing to Furnish Copy B to the Partner: Filing with the IRS but forgetting to send Copy B to the foreign partner, preventing them from filing their own U.S. tax returns on time.
- Foreign Partner Forgetting to Attach Copy B: When the foreign partner files Form 1040-NR or Form 1120-F, failing to physically or digitally attach Copy B of Form 8805. The IRS will reject the withholding credit without the physical attachment.
Penalties for Non-Filing or Errors
Failing to comply with Form 8805 rules triggers statutory penalties for both the partnership and the foreign partner:
- Information Return Penalties (IRC § 6721): The IRS assesses penalties starting at over $330 per form for failing to file correct Forms 8805 with the IRS, with annual maximums exceeding $3 million for large partnerships.
- Payee Statement Penalties (IRC § 6722): A separate penalty of up to $330 applies for each failure to furnish a timely, accurate Copy B to the foreign partner.
- Intentional Disregard: If the IRS determines the partnership deliberately refused to file or issue Forms 8805, the penalty increases to 10% of the aggregate amount required to be reported with no statutory maximum cap.
- Partner Refund Denials: If Form 8805 is missing or flawed, the foreign partner’s refund claim will be denied by IRS automated processing.

Frequently Asked Questions
1. How does a foreign partner get a refund if too much tax was reported on Form 8805?
The foreign partner must file an annual U.S. income tax return (Form 1040-NR for individuals or Form 1120-F for corporations) and attach Copy B of Form 8805. On the return, they calculate their actual tax liability and claim the Form 8805 withholding as a payment credit. If the credit exceeds their actual tax, the IRS issues a direct refund check or bank transfer.
2. What is the difference between Form 8805 and Schedule K-1?
Schedule K-1 reports the partner’s allocable share of business income, deductions, and credits for income tax purposes. Form 8805 reports the actual cash withholding tax paid by the partnership to the IRS on that income under Section 1446.
3. Can a foreign partner use Form 8805 to prove U.S. tax compliance in their home country?
Yes. Many foreign governments and tax authorities accept Form 8805 (alongside the filed Form 1040-NR) as official proof of foreign taxes paid in the United States to claim foreign tax credits in their home jurisdiction under double taxation treaties.
4. What should a partnership do if a foreign partner’s address changes?
If a foreign partner’s address changes, the partner should submit an updated Form W-8BEN or W-8BEN-E to the partnership. The partnership uses the new address when preparing Form 8805 for that tax year.
5. Can Form 8805 be submitted electronically?
Currently, Copy A of Form 8805 is submitted as a physical paper attachment to Form 8804 mailed to the IRS Service Center in Ogden, Utah. Partnerships should check current IRS Modernized e-File guidelines for updates regarding electronic batch filing.
6. What happens if a partnership files an amended Form 8804?
If the partnership files an amended Form 8804 that alters a foreign partner’s income or withholding, the partnership must check the “Amended” box at the top of Form 8805, complete the corrected figures, file Copy A with the amended Form 8804, and furnish corrected Copies B and C to the foreign partner immediately.
Conclusion: Key Takeaways
IRS Form 8805 is the critical individual reporting document that connects Section 1446 partnership withholding to a foreign partner’s personal U.S. tax account. By documenting each partner’s share of Effectively Connected Taxable Income and verified tax prepayments, it ensures full transparency and compliance across cross-border investments.
Partnerships must ensure that every foreign partner holds a verified U.S. Taxpayer Identification Number, verify that individual Form 8805 totals reconcile perfectly with Form 8804, attach Copy A to the annual master return, and furnish Copies B and C to foreign partners on time so they can claim their withholding credits.
