Foreign Partners in a U.S. Multi-Member LLC: Form 1065, Section 1446 Withholding and Forms 8804/8805

A multi-member LLC is taxed as a partnership unless it elects otherwise. It files Form 1065 every year. If it earns income effectively connected with a U.S. trade or business and part of that income is allocable to foreign partners, the LLC generally must pay withholding tax on that share — whether or not it distributes any cash — and report it on Forms 8804, 8805 and 8813. Each foreign partner then generally files a U.S. return to report the income and claim credit for the tax withheld.

Why is the LLC responsible for its partners' tax?

The IRS cannot easily collect tax from partners who live abroad. Section 1446 shifts that responsibility to the partnership: it acts as a withholding agent for the foreign partners' share of effectively connected taxable income (ECTI). The withholding rate is generally the highest individual rate for individual partners and the corporate rate for corporate partners, applied to their allocable share — not to distributions.

Which forms are involved?

• Form 1065 — the partnership's annual information return (income tax is not paid at the partnership level).
• Schedule K-1 and Schedule K-3 — each partner's share of income, deductions, credits and international items.
• Form 8813 — quarterly installment payments of Section 1446 tax during the year.
• Form 8804 — the annual return summarizing the partnership's total Section 1446 withholding.
• Form 8805 — a statement for each foreign partner showing the tax paid on their behalf; the partner attaches it to their own return.

What does each foreign partner file?

An individual foreign partner generally files Form 1040-NR, reports the K-1 income, and claims the Form 8805 withholding as a credit. If the withholding exceeds the actual tax, the difference may be refunded. A foreign corporate partner generally files Form 1120-F. Partners usually need a U.S. taxpayer identification number — typically an ITIN for individuals — to file and to receive credit.

What if the LLC has no U.S. effectively connected income?

Section 1446 withholding applies to effectively connected income. If the partnership's income is not ECI — for example, certain services performed entirely outside the United States — Section 1446 may not apply. But the partnership still files Form 1065 and issues K-1s, and other withholding rules (such as Chapter 3 withholding on U.S.-source passive income) may apply instead. This conclusion depends on the facts and should be documented.

Practical example

Ana (resident of Venezuela) and David (U.S. citizen in Miami) each own 50% of a Florida LLC operating a logistics business from a Doral warehouse. The LLC earns $200,000 of net income, all ECI. Ana's $100,000 share is subject to Section 1446 withholding at the applicable rate, paid through quarterly Forms 8813. The LLC files Form 1065, Form 8804 and gives Ana a Form 8805. Ana files Form 1040-NR, reports her K-1 income, and credits the withholding. David reports his share on his regular Form 1040; no Section 1446 withholding applies to him.

Common mistakes we see

• Assuming no withholding is due because no cash was distributed.
• Filing Form 1065 but never filing Forms 8804/8805.
• Foreign partners never filing a 1040-NR, leaving withholding credits unused.
• Missing W-8BEN or W-8BEN-E documentation from partners, which can lead to incorrect withholding.
• Partners treated informally on the books, making it hard to track capital accounts.

Selling an interest in the partnership

If a foreign partner sells or redeems their interest in a partnership engaged in a U.S. trade or business, the gain may be treated as ECI, and the buyer (or the partnership) may be required to withhold under Section 1446(f). Planning before a sale is important to avoid surprises at closing.
