Key Takeaways

The partnership does not end when a partner is deported, but the tax filings change the day they leave.
The deported partner becomes a nonresident alien (NRA) for U.S. tax purposes on the date of deportation. The partnership must withhold under IRC § 1446 on the partner's allocated income from that day forward.
The partner files Form W-8BEN. The partnership files Form 8804 annually, Form 8805 annually, and Form 8813 quarterly.
The year's income must be allocated between the residency period and the non-residency period using either interim closing of the books or proration. Pick the method, document it that year, and apply it consistently.
A C-corporation blocker can avoid the § 1446 withholding but creates corporate tax plus 30 percent dividend withholding under § 1442. For most small partnerships, the blocker costs more in tax than the withholding it was meant to avoid.

Some of the most entrepreneurial business owners I work with came to this country as immigrants. They built service companies, restaurants, construction firms, and small partnerships that now employ U.S. citizens and pay U.S. taxes. When one of those partners gets deported, the business does not stop. But the tax rules that apply to that business change the day they leave the country, and the partnership has filings and withholding obligations that most owners do not know exist until the IRS sends a notice.

Here is the short version of what to expect and what to file.

The First Thing To Check: Your W-9s

If you have a partnership and you do not have a properly signed Form W-9 on file for every partner, the IRS presumes every partner is a foreign partner. That is the default rule under Treas. Reg. § 1.1446-1(c)(1) through (3). The W-9 is the document that establishes a partner's U.S. tax status on the date it is signed, and it is the evidence the partnership relies on if anyone ever questions whether you did your due diligence.

If you do not have current W-9s for every partner, fix that immediately. It costs nothing and it protects the partnership from a withholding determination that, in most cases, was never necessary in the first place.

What Changes When a Partner Becomes a Nonresident Alien

When a partner is deported, they become a nonresident alien (NRA) for U.S. tax purposes as of the date of deportation. From that day forward, the partnership has two new obligations under IRC § 1446.

First, the partner needs to complete Form W-8BEN instead of a W-9. The W-8BEN is the document that establishes NRA status and, in some cases, claims treaty benefits.

Second, the partnership becomes a withholding partnership. It is required to withhold tax on two categories of income allocated to the NRA partner:

Effectively Connected Taxable Income (ECTI). This is the partner's share of the partnership's U.S. trade or business income. Withholding is required at the highest applicable rate under IRC § 1446.

Fixed, Determinable, Annual, or Periodical income (FDAP) that is not effectively connected with a U.S. trade or business. This includes things like portfolio interest, dividends, and certain royalties. Withholding is required at 30 percent, or a lower treaty rate if one applies.

The administrative weight of this is not as heavy as people assume, but it does require the partnership to produce clean financial statements regularly. If your bookkeeping is current, the additional work is mostly mechanical. If your bookkeeping is not current, the additional work is where the cost shows up.

Does The Partnership End When a Partner Is Deported?

This is the question I get first, and the answer is no. The partnership continues. The deported partner can still own the same percentage interest. Income still flows through to that partner.

What changes is allocation. The partnership now must split the year into two periods for that partner. The residency period covers the months they were a U.S. tax resident. The non-residency period starts the day of deportation. Income allocated to the non-residency period is subject to ECTI and FDAP withholding under § 1446. Income allocated to the residency period is reported the way it always was.

If the partnership uses a calendar year and the partner is deported in August, for example, then roughly two-thirds of that year's allocated income is residency-period income and one-third is non-residency-period income. The exact allocation method depends on the partnership agreement and the nature of the income. There are interim closing of the books options and proration options. Pick the method, document it, and apply it consistently.

Which Allocation Method Should You Use?

In practice, the right choice depends on how evenly the partnership's income arrives during the year. If the business has steady monthly income, proration based on the number of days in each period is simpler, less expensive, and produces a defensible result. If the business has big one-time events that fall on one side of the deportation date or the other, interim closing of the books gives a more accurate picture and protects the remaining partners from absorbing tax allocations that should economically belong to the NRA period, or the other way around.

Whichever method you choose, make sure to document it in writing the same year. If the IRS examines the return three years later, an after-the-fact reconstruction of the allocation method is much harder to defend than a short memo prepared in the year of deportation. Producing that memo at the time is far less expensive than recreating it later.

What About a Blocker Corporation?

Some owners ask whether the NRA partner can hold their interest through a U.S. domestic C corporation, sometimes called a blocker, to avoid the § 1446 withholding rules. The answer is yes, you can do that, but you trade one set of filings for another.

The blocker corporation files Form 1120. The corporation pays U.S. corporate tax on its share of partnership income at the regular corporate rate. When the corporation distributes a dividend back to the NRA shareholder, the corporation must withhold 30 percent, or a lower treaty rate if available, under IRC § 1442 on that dividend.

So, a blocker eliminates the partnership-level withholding headache but creates a corporation-level tax plus a dividend-withholding obligation. For most small partnerships, the blocker structure costs more in tax than the § 1446 withholding it was meant to avoid. It can make sense in larger partnerships with sophisticated income streams, but it is not a default move.

What You Should Do Immediately If You Find Yourself In This Situation

Confirm Form W-8BEN is on file for the deported partner, dated as of the deportation date. If it is not, request it now.
Talk to your CPA about the allocation method for the year of deportation. The decision is straightforward, but it must be made and documented before you file the partnership return.
Make sure withholding is being calculated and remitted quarterly on the non-residency portion of allocated income. The partnership files Form 8804 and 8805 annually to report the withholding, and Form 8813 quarterly to remit it.

If you have a partner who has been deported, or who may be in a situation where this could happen, you should contact a CPA who handles international filings before the next quarter ends. The default outcome if you elect to do nothing will likely be very expensive. The structured approach, where you make the elections and file the right forms, is usually far more manageable.

This blog covers the most common partnership situation. There are exceptions for certain treaty positions, publicly traded partnerships, and partnerships with tiered foreign ownership that are beyond the scope of one post. If your facts are more complex than what is described here, the same advice applies: please get qualified counsel before the year closes.

Frequently Asked Questions

Does The Partnership End When a Partner Gets Deported?

No. The partnership continues, and the deported partner can still own the same percentage interest. What changes is the tax treatment for the period after deportation. The partnership becomes a withholding partnership under IRC § 1446 for the deported partner's share of effectively connected and FDAP income, and the year's income has to be allocated between the residency period and the non-residency period.

What Forms Does The Partnership Have To File?

After deportation, the partner completes Form W-8BEN to establish nonresident alien status. The partnership files Form 8804 (annual withholding return) and Form 8805 (foreign partner information statement) annually, plus Form 8813 quarterly to remit the withholding.

Does a Blocker Corporation Eliminate The Withholding Obligation?

A U.S. C corporation can hold the partnership interest and avoid Section 1446 withholding, but the corporation then files Form 1120, pays corporate tax on its share of partnership income, and must withhold 30 percent, or a lower treaty rate, on dividends paid to the nonresident alien shareholder under IRC § 1442. For most small partnerships, this trade is more expensive than the original withholding.
