What Breaks a Puerto Rico Tax Home in the Middle of a Year

What the Tax Home Test Actually Requires

Bona fide Puerto Rico residency turns on three separate tests. The presence test, the 183 day count One83 helps you track, is only one of them. Tax home is a different question: where does your regular or principal place of business actually sit, not how many days you spent on the island.

Under 26 CFR 1.937-1, your tax home is your regular or principal place of business. No fixed place of business? Then your tax home falls back to your regular place of abode in a real and substantial sense. IRS Publication 570 puts it almost the same way: your tax home is your regular or main place of business, employment, or post of duty, regardless of where you keep your family home.

The general rule doesn't bend much on timing. Outside a narrow exception covered below, you cannot have a tax home outside Puerto Rico during any part of the taxable year and still pass the test for that year. That phrase, any part of the taxable year, is why a mid year change matters so much more here than it does under the presence test, where days simply add up or they don't.

Not every day-counting exception carries over to the tax home test. One83's guide on the medical treatment day exception covers a related but distinct carve-out for the presence test's day count, not for where your regular place of business sits. Keep the two tests separate in your own recordkeeping.

The Mid-Year Break: Stateside Jobs and Mainland Offices

Here's the failure mode that catches established residents off guard. Someone spends January through August in Puerto Rico, clears the 183 day threshold without much drama, then accepts a stateside role or opens a mainland office in September. The presence test for the year may still look fine on paper. The tax home test does not.

Tax home is defined by where your regular or principal place of business sits, so moving that place off island in September relocates your tax home for the rest of the year. The general rule applies to any part of the taxable year, not just a majority of it. A resident who was fully compliant through August can still fail the tax home test for the full year once the business relocation happens, unless the year of the move exception described below applies.

A short business trip off island is not the same thing. The test looks at your regular or principal place of business, not at where you happened to be on a given work trip. What actually breaks it is a real relocation of that regular place of business: a new stateside employer, a mainland office you now report to, a business that has genuinely moved its center of operations off the island.

The regulation carves out a few narrow situations where a tax home outside the possession doesn't count against you: employment on a vessel used predominantly in local and international waters, and days spent as an elected representative, government employee, or student, per 26 CFR 1.937-1. These carve-outs are specific to those situations. An ordinary remote job or a second mainland office doesn't fall under them.

The Year of the Move Exception (and Its Limits)

There is real relief available here, but it's narrower than most people expect. The year of the move exception, found in 26 CFR 1.937-1(f)(2)(ii), lets someone who changes their tax home mid year still claim bona fide residency for the part of the year before the change.

The gate is a two prior year requirement. This exception only applies if you were already a bona fide resident of Puerto Rico for at least the two tax years immediately before the year of the move, confirmed in both Publication 570 and the Form 8898 instructions. Someone in their first or second year of residency who relocates their tax home mid year has no partial year fallback under this specific provision. That timing detail matters a lot if you're still inside your own first partial year of residency, where the rules already work differently than they do for an established resident.

The regulation's own example is worth walking through directly. Picture someone who continues to reside and maintain a principal place of business in Puerto Rico through April, then moves and changes their tax home on May 5. If they meet the two prior year requirement, they're treated as a bona fide resident of Puerto Rico from January 1 through May 4, the day before the change, not for the full year. The Form 8898 instructions give a parallel worked example: a taxpayer who moved from Puerto Rico to Florida in May qualifies as a bona fide resident for the part of the tax year before the move, under the same conditions.

Hold onto that distinction. The exception salvages the months before the move. It doesn't extend full-year residency status to someone who changed their tax home partway through the year. If your tax home moves off island in September, this provision, even when it applies to you, only protects January through the day before the change. Not the full calendar year.

The Closer Connection Condition Runs Alongside the Exception

The two prior year rule isn't the only condition. To claim the year of the move exception, you also have to have maintained a closer connection to Puerto Rico than to the United States or a foreign country throughout the part of the year before your tax home changed, per 26 CFR 1.937-1.

That means the tax home timing and the closer connection question get evaluated together, not separately. You can get the tax home date exactly right, correctly identify May 5 as your change date, and still fail the exception if the facts show your closer connection had already tipped toward the mainland earlier in the year: where your family lived, where you banked, where you were registered to vote, and similar factors. One83's guide to the closer connection test walks through the full factor list the test weighs.

Treat the two conditions as a single package when documenting a mid year move. A clean tax home date on its own isn't enough if the closer connection facts don't support the same timeline.

Remote Workers and the Itinerant Tax Home Rule

Remote work adds a wrinkle the regulation addresses directly. If you don't have a regular place of business because of the nature of your work, you're treated as an itinerant, and your tax home becomes wherever you're currently working, per Publication 570 and the Form 8898 instructions.

For someone splitting time between Puerto Rico and the mainland without a fixed employer location, this shifts the question away from the presence day ledger and toward where the work is actually performed at a given point in the year. A remote worker genuinely based in Puerto Rico, working for clients or an employer without requiring a specific office, sits in a different position than someone who is itinerant in the sense the regulation describes: moving between work locations with no fixed base.

This is exactly the kind of fact pattern where general guidance stops being enough. If your work arrangement doesn't map cleanly onto either a fixed regular place of business or a clearly itinerant pattern, that's a conversation for a licensed tax professional who can look at your actual facts, not a rule you can apply from a checklist.

Frequently Asked Questions

Does taking a stateside job in the middle of the year break Puerto Rico bona fide residency?

It can. The tax home test requires that you not have a tax home outside Puerto Rico during any part of the tax year. Tax home is defined as your regular or principal place of business, so moving that place off island partway through the year fails the test for the full year unless the year of the move exception applies to you.

What is the year of the move exception?

It is a narrow rule in 26 CFR 1.937-1(f)(2)(ii) that preserves bona fide residency for the part of the year before your tax home changed, but only if you were already a bona fide resident of Puerto Rico for at least the two prior tax years and you kept a closer connection to Puerto Rico than to the United States throughout the period before the move.

Does the year of the move exception help someone in their first year of residency?

No. The exception requires at least two full prior tax years as a bona fide resident of Puerto Rico. Someone in year one who relocates their tax home mid year has no partial year fallback under this provision.

How does a remote worker's tax home get determined?

If you have no fixed regular place of business, you are treated as an itinerant and your tax home is wherever you are currently working. A remote worker splitting time between Puerto Rico and the mainland needs to look at where the work is actually performed, not just where they happen to be physically present on a given day.

Do I need to file anything if my tax home changes mid year?

Yes. If your worldwide gross income is $75,000 or more for the year, you must file Form 8898 for the year you moved to or from Puerto Rico. Married filers each file a separate form.

Conclusion

The tax home test doesn't run on a day count. It runs on the full year, and a single mid year relocation of your regular or principal place of business off island is enough to break it, independent of how the presence test comes out. Worth sitting with if your plans for the second half of the year involve a stateside role or a mainland office.

The year of the move exception is real relief, but it's built for established residents, not new arrivals: two prior years of bona fide residency and a closer connection to Puerto Rico maintained right up until the change. Even then, it only protects the months before the move, not the full year.

An automatic day ledger is what One83 keeps for you, tracking the presence test day by day. Tax home is a separate test with its own timeline, and it deserves its own documentation alongside the day count, not an assumption that one test covers the other.
