The year you move to Puerto Rico is the most complex year from a compliance standpoint. The bona fide residency test under IRC §937(a) normally requires that all three prongs—the presence test, the tax home test, and the closer connection test—be satisfied for the entire taxable year. In a partial year of residence, meeting these standards in full can be difficult or impossible.

The Treasury Regulations address this through a safe harbor at Treas. Reg. §1.937-1(f)(1), which provides relief for the tax home and closer connection tests in the year of the move. Understanding what this safe harbor covers—and what it does not—is critical to structuring a successful relocation.

The Three Conditions of the Safe Harbor

Under the year-of-move safe harbor, you will be treated as satisfying the tax home and closer connection tests for the entire taxable year of the move if you meet all three of the following conditions:

Condition 1: No prior residency. You were not a bona fide resident of Puerto Rico for each of the three taxable years immediately preceding the year of the move. This condition ensures the safe harbor is available to genuine newcomers, not individuals who are cycling in and out of residency.

Condition 2: No mainland tax home or closer connection for the last 183 days. You did not have a tax home outside Puerto Rico, and did not have a closer connection to the United States or a foreign country than to Puerto Rico, for each of the last 183 days of the taxable year of the move. For a calendar-year taxpayer, this means from approximately July 2 through December 31.

This is the operative requirement. By the midpoint of the year, your tax home must be in Puerto Rico and your closer connection must favor Puerto Rico over the mainland. Achieving this requires that, by early July, you have relocated your principal place of business, established your primary residence, and shifted the balance of your personal and administrative ties to Puerto Rico.

Condition 3: Intent to remain. You are, or have the intent to become, a bona fide resident of Puerto Rico for each of the three taxable years immediately following the year of the move. This is a forward-looking requirement. The intent must be genuine, and it must be demonstrated by subsequent compliance with all three prongs of the residency test in those following years. Failing to maintain bona fide residency in the three subsequent years can retroactively undermine the safe harbor for the move year.

What the Safe Harbor Does Not Cover

The safe harbor applies only to the tax home test and the closer connection test. It does not relax the presence test. You must independently satisfy one of the five alternative presence test standards in the year of the move.

For a mid-year relocation, this creates a practical challenge. If you move to Puerto Rico in June, you have approximately 210 remaining days in the year—enough to meet the 183-day presence test if you remain in Puerto Rico for the balance of the year. If you move later—say, in August—you may have difficulty reaching 183 days of presence by December 31.

Some individuals may be able to satisfy one of the alternative presence tests (the 549-day rule, the 90-day U.S. limitation, or the no-significant-connection standard) even in a partial year, depending on their specific travel patterns and mainland connections. But the 183-day rule is the most commonly used, and for mid-year movers, timing the relocation early enough to accumulate 183 days is a central planning consideration.

Timing the Move

The safe harbor conditions have direct implications for the timing of your relocation:

Moving earlier in the year provides more margin. Moving after approximately July 2 makes the 183-day presence test effectively impossible under that alternative, though other alternatives may still be available.

What Must Be In Place by the Midpoint

The safe harbor’s second condition requires that, from approximately July 2 onward, your tax home is in Puerto Rico and your closer connection favors Puerto Rico. To satisfy this by the midpoint, you should plan to have the following completed before July 2:

• Primary residence established in Puerto Rico
• Principal place of business located in Puerto Rico
• Mainland home sold, rented out, or vacated (no longer a “permanent home”)
• Driver’s license issued by Puerto Rico
• Voter registration transferred to Puerto Rico
• Primary banking relationships moved to Puerto Rico
• Mailing addresses updated
• Social, civic, and professional memberships established in Puerto Rico

These steps serve double duty: they satisfy the safe harbor requirements and simultaneously strengthen your position on the closer connection test going forward.

Consequences of Failure

If the safe harbor conditions are not met, you are evaluated under the standard three-part test for the full year. For a partial-year mover, satisfying the tax home and closer connection tests for the entire year (including the period before the move, when your tax home was presumably on the mainland) is likely to be difficult or impossible without the safe harbor. The result would be failure to qualify as a bona fide resident for the move year, with full federal taxation on any income claimed as excluded under §933.

Additionally, failure to maintain bona fide residency in the three subsequent years can retroactively invalidate the safe harbor for the move year itself. The three-year forward commitment is not optional.
