Strategy Snapshot
Section 1446 withholding is triggered by the allocation of effectively connected income to a foreign partner — not by a cash distribution. Partnerships that miss this often discover the problem during a sale or audit.
A U.S. partnership allocates effectively connected taxable income to a nonresident partner, whether or not any cash is actually distributed.
The partnership must withhold on the foreign partner's allocable share, file Form 8804 annually, and issue Form 8805 to each foreign partner.
Treating Section 1446 as the foreign partner's problem. The withholding obligation belongs to the partnership, and the exposure for noncompliance sits there too.
U.S. real estate partnerships with foreign partners carry a withholding obligation that many partnerships either overlook or misunderstand. Section 1446 requires the partnership to withhold on a foreign partner’s allocable share of effectively connected taxable income — not on distributions, not on cash flow, but on the income allocation itself. A partnership that collects rent, allocates it to a foreign partner, and reinvests the cash still owes withholding for that year.
Section 1446 withholding belongs to the partnership. The foreign partner’s failure to file does not excuse the partnership from its own obligations.The compliance issue
How Section 1446 Works in a Real Estate Context
When a U.S. partnership owns rental property and allocates effectively connected income to a nonresident partner, the partnership must withhold on that allocation. The withholding rate is generally 37 percent for individual foreign partners and 21 percent for foreign corporate partners.
Rental income from U.S. real estate is the most common trigger. Depreciation and mortgage interest reduce net taxable income, but they do not eliminate the withholding obligation if income remains. When the property is sold, the gain allocation to foreign partners creates a second, often larger, withholding event that the partnership must address before or at closing.
The Partnership Filing Stack
At the partnership level, Section 1446 compliance involves:
- Form 8813 — quarterly withholding payments due in April, June, September, and December
- Form 8804 — the annual Section 1446 withholding tax return, due March 15 (or September 15 with extension)
- Form 8805 — issued to each foreign partner by the same deadline, showing their allocable share of income and the withholding credited to them
The partnership is responsible for these filings regardless of whether the foreign partner separately complies with U.S. reporting requirements.
Key Due Dates
| Filing | Standard Due Date | Extended Due Date |
|---|---|---|
| Form 8813 (quarterly payments) | April 15, June 15, Sept 15, Dec 15 | No extension available |
| Form 8804 (annual return) | March 15 | September 15 |
| Form 8805 (foreign partner statement) | March 15 | September 15 |
| Foreign partner Form 1040-NR | June 15 | October 15 |
Quarterly payments are not extendable. Underpayment of quarterly installments can result in penalties even when the annual return is filed on time.
The Foreign Partner’s Filing Obligation
Receipt of a Form 8805 does not end the foreign partner’s U.S. filing obligation. The foreign partner must still file Form 1040-NR to:
- Report their share of effectively connected rental or gain income
- Claim credit for the Section 1446 withholding shown on Form 8805
- Report any other U.S. effectively connected income for the year
The 1040-NR and the partnership’s 8804/8805 filing need to be coordinated so the withholding credit is applied correctly and no amount is over- or under-reported.
Sale-Year Withholding
A sale of the underlying real estate is often the highest-stakes Section 1446 event. The gain allocation to foreign partners in the sale year can be large, and the partnership must account for withholding on that gain through the 8804 filing for that year. This overlaps with FIRPTA, which imposes a separate withholding obligation at closing based on the gross sales price. Both obligations need to be reviewed before closing — not after.
When to Get Help
If you are a U.S. real estate partnership with foreign partners, or a foreign investor who is a partner in a U.S. property entity, Section 1446 compliance requires coordination at both the partnership and partner level. We prepare the partnership’s 8804/8805 filing, quarterly 8813 payments, and the foreign partner’s 1040-NR when the engagement includes both sides.
