If your restaurant or bar is structured as a partnership with foreign partners, you may have an obligation to withhold and remit U.S. federal income taxes on their behalf and file additional forms with your partnership tax return.
A restaurant group, restaurant, or bar structured as a partnership with foreign partners generates “income effectively connected with a U.S. trade or business (Effectively Connected Income, or ECI)”. Therefore, the partnership is responsible for withholding and paying tax on each foreign partner’s share of effectively connected taxable income (ECTI).
The logic and intent behind this requirement are that the IRS wants you to pay the foreign partner’s share of income tax on the income generated by your business to ensure that the foreign partner is paying their share of U.S. income taxes on U.S.-sourced income. Otherwise, the foreign partner could simply forgo filing a U.S. tax return and paying U.S. taxes.
The intent and logic behind foreign partner tax withholding are akin to the withholding you do for your employees through their paychecks. The foreign partner will then need to file a personal (Form 1040NR) or corporate (Form 1120-F) tax return to claim a credit for the partnership’s taxes paid on their behalf. They may receive a refund or owe additional taxes, depending on their other sources of income and deductions, similar to a W-2 employee filing their personal tax returns.
For example, assume Doe Restaurant Group generates $1m in taxable profit for the tax year 2025, and has a foreign partner that is entitled to $200,000 of that profit because they own 20% of the company. You’re required to calculate the taxes owed on their share of the $200,000 and remit them to the IRS on their behalf.
The tax withholding payment is not an expense to the partnership; it is treated as a distribution or advance/loan to the partner because it’s an income tax payment made on behalf of the partner. As a result, the estimated tax payment must be withheld from future distributions, or the benefiting partner must repay it.
It’s important to remember that the tax withholding is calculated on Effectively Connected Taxable Income (ECTI), not distributions. If the partnership generates $1m in ECTI and doesn’t issue any distributions, the partnership is still liable to calculate and remit withholding taxes on behalf of the foreign partner.
In this article, we’ll show you how to identify foreign partners and ECI, calculate the withholding amounts, and remit the proper tax payments and forms to the IRS.
Identifying Foreign Partners and Effectively Connected Income (ECI)
The IRS distinguishes between a U.S. person and a foreign person primarily based on their residency and citizenship. An individual is considered a U.S. person for tax purposes if they are a U.S. citizen or a resident alien who meets either the Green Card Test or the Substantial Presence Test. Otherwise, they are considered a foreign person.
When a foreign person or nonresident alien engages in a trade or business in the U.S., all income from sources within the U.S. connected with the conduct of that trade or business is Effectively Connected Income (ECI). Here are the criteria for determining whether your partnership has ECI. If you are a restaurant, bar, nightclub, or restaurant group with a physical location in the U.S., you likely have ECI. Income from the rental of real property for a restaurant, bar, or nightclub may be treated as ECI if the taxpayer elects to do so.
Partners claiming to be U.S. persons must complete and submit a Form W-9 to the partnership verifying their status. A partnership must also collect a Form W-8 from any non-U.S. partner before making any payments or allocating any income to them. The W-8 form type will vary depending on the type of foreign partner.
Calculating the Partnership Tax Withholding Amount
The final amount of foreign tax withholding is calculated and reported on Form 8804 – Annual Return for Partnership Withholding Tax, which is due on March 15 for the previous year for calendar year taxpayers. ECTI typically equals the income reported on each foreign partner’s K-1. Therefore, the partnership tax return (Form 1065) should be prepared before the Form 8804. The tax rates below are used to calculate the amount of total tax owed on the foreign partner’s share of ECTI:
- Non-corporate foreign partners = 37% of ECTI
- Corporate foreign partner = 21% of ECTI
Continuing the example from above, assume John Doe’s 2025 K-1 shows $190,000 in box 1 ordinary income and $10,000 in box 5 interest income, and he’s the only foreign partner in the partnership. The ECTI for the year would be $200,000, and the foreign tax withholding owed is $74,000 (37% x $200,000).
The partnership files Form 8804 to report the total of all foreign partners’ share of ECTI and foreign tax withholding. A Form 8805 is then issued to each partner (like a K-1) to report each partner’s share of the foreign tax withholding, which they can claim as a credit on their personal tax returns.
Required Filings, Payments, and Safe Harbor Rules
Like any other federal tax, you must calculate and remit quarterly estimated tax payments towards your annual foreign tax withholding obligation; otherwise, you will be penalized. If the total withholding tax for a quarter is under $500, the partnership doesn’t have to make a quarterly payment under the de minimis rule.
Each quarterly payment covers the total tax owed for all foreign partners based on their share of ECTI. The partnership can calculate these installments using prior-year figures or current-year estimates to match the income as it’s earned.
By using the prior year safe harbor, no penalty for underpayment will be imposed on the partnership if:
- The amount of each installment payment equals 25% of the withholding tax that would be payable on the amount of a partnership’s ECTI allocable to foreign partners for the prior year;
- The prior tax year consisted of twelve months;
- The partnership filed Form 1065 for the preceding year; and
- The amount of ECTI for the prior year was not less than 50% of the ECTI as shown on the current year’s Form 8804.
Similarly, the current-year safe harbor rule allows no penalty for underpayment to be imposed on the partnership if each installment payment equals 25% of the withholding tax payable on the partnership’s ECTI allocable to foreign partners for the current tax year.
Given the uncertainty and variability in the restaurant and bar industry, and the time required to estimate and project current-year income, we prefer to use the prior-year safe harbor by completing line 8 of the 8804-W, unless the net income for the current year is expected to be significantly less than the prior year.
The estimated quarterly payment will be submitted using Form 8813. Payments are due 4/15, 6/15, 9/15, and 12/15. As mentioned above, the payment should be recorded as a distribution or advance to the foreign partner and reduced from future distributions.
Penalties and Interest for Underpayment of Foreign Tax Withholding
Interest is charged on any unpaid taxes and related penalties from the due date (including extensions) until payment is made. A penalty of 0.5% per month, up to a maximum of 25%, applies to late tax payments unless the taxpayer shows reasonable cause. Additional penalties may apply for failures to withhold required taxes or for inaccuracies due to negligence, substantial understatements, valuation misstatements, or fraud.
The quarterly payments are counted towards the total tax for the year as calculated and reported on Form 8804. When filing the 8804, you will pay the balance for any underpayment or request a refund or carry forward for overpayment.
Summary of Forms for Foreign Partner Withholding Compliance
In conclusion, partnerships must use three forms to report and pay withholding tax on ECTI allocable to foreign partners:
- Form 8804 reports the partnership’s total annual withholding tax liability and transmits Form 8805;
- Form 8805 details each foreign partner’s share of ECTI and corresponding tax payments, with copies sent to both the partner and attached to Form 8804; and
- Form 8813 is used for making quarterly withholding tax payments.
If you’re a partnership with foreign partners, you must file Forms 8804 and 8805 even if no withholding liability exists. You must also notify each foreign partner within 10 days of each tax withholding payment so that the partner can credit the installment toward their own estimated tax. It’s worth noting that if the partnership’s agent providing notice is the same person who acts as agent for the partner in preparing the partner’s U.S. return, then the 10-day notice requirement may be waived. Also, if the partnership has at least 500 foreign partners and the total foreign withholding tax required for those partners is less than $1,000, then the 10-day notice is not required. (i.e., for de minimis amounts).
Managing Restaurant Partnership Tax Withholding
Managing tax withholding obligations for foreign partners can be complex, especially in the fast-paced restaurant and bar industry, where income and ownership structures often fluctuate. Ensuring compliance with the IRS’s partnership withholding rules under IRC §1446, including proper calculation of ECTI, timely remittance of Form 8813 payments, and adherence to the 10-day notification requirement under §1.1446-3—is critical to avoiding costly penalties and preserving good standing with tax authorities.
