Foreign Partner

A foreign partner is any non-U.S. person (individual or entity) that holds an ownership interest in a U.S. partnership or multi-member LLC taxed as a partnership — triggering specific withholding, reporting, and compliance obligations under the Internal Revenue Code. Under IRC Section 1446, a U.S. partnership must withhold tax on effectively connected taxable income (ECTI) allocable to foreign partners at the highest applicable rate: 37% for non-corporate foreign partners and 21% for corporate foreign partners. This withholding serves as a prepayment against the foreign partner's U.S. tax liability and must be deposited using IRS Form 8813 (Partnership Withholding Tax Payment Voucher) on a quarterly basis if the estimated withholding exceeds $500. Additionally, under the Foreign Investment in Real Property Tax Act (FIRPTA), partnerships selling U.S. real property interests must withhold 15% of the amount realized allocable to foreign partners. The partnership itself must file Form 8804 (Annual Return for Partnership Withholding Tax) and issue Form 8805 (Foreign Partner's Information Statement of Section 1446 Withholding Tax) to each foreign partner by the partnership return due date. Foreign partners also receive Schedule K-1 (Form 1065) showing their distributive share of partnership income, deductions, and credits, and must file Form 1040-NR (U.S. Nonresident Alien Income Tax Return) to report this income and claim credit for taxes withheld. Failure to withhold under Section 1446 exposes the partnership to liability for the unwitheld tax plus interest and penalties. doola assists multi-member LLCs with foreign partners in managing these complex withholding calculations and filing obligations to ensure full compliance.
