Remote Job, Mainland Employer: Where Is Your Tax Home?

Does a mainland employer put your tax home outside Puerto Rico?

Not by itself. Tax home is determined by where you actually do the work, not by where your employer is incorporated, headquartered, or where the payroll department sits. Live in Puerto Rico and do your job from there day to day, and that is the fact pattern the tax home test cares about, no matter what state is printed on your W-2.

It is one of the most common questions from people building a bona fide residency case: a mainland job, kept after the move, worked entirely from a Puerto Rico address. The presence test gets most of the attention because it produces a single number, the day count. Tax home is a separate test with its own logic. It is worth understanding on its own terms before you assume the day count settles the question.

What does "tax home" mean under IRC section 937?

Bona fide residency in Puerto Rico requires passing three independent tests: presence, tax home, and closer connection. All three must be satisfied for the year. Publication 570 states the tax home requirement plainly: your tax home is your regular or main place of business, employment, or post of duty, regardless of where you maintain your family home.

That one sentence is the whole test. It is not about citizenship. It is not about where you vote, or which state issued your driver's license, those questions belong to the closer connection test. Tax home asks one thing: where is your regular place of work.

Section 937(a)(2) does not define tax home from scratch. It borrows the definition already built into section 911(d)(3) of the tax code, the same provision that governs the foreign earned income exclusion. The implementing regulation, 26 CFR section 1.937-1, carries this definition forward: an individual's tax home is located at their regular or principal place of business, and only when no such place exists does the analysis fall back to a place of abode.

For the three test framework in overview, the tests in overview page walks through presence, tax home, and closer connection together, and links back here for the tax home mechanics specifically.

Where does the regulation say your tax home actually sits?

For most fully remote workers, the answer is simple. Your regular place of business is wherever you regularly sit down and do the job. A home office in Puerto Rico, five days a week, is your regular place of business under the section 911(d)(3) test that section 937 imports.

The regulation does carve out one explicit exception, and it is instructive because of what it is not about. 26 CFR section 1.937-1 provides that employment on a ship or other seafaring vessel, predominantly used in local and international waters, does not by itself create a tax home outside the possession. That exception exists because a ship's work location is genuinely ambiguous in a way an office is not. The drafters address employer or location mismatches directly when they intend to, and there is no parallel carve out written for a remote employee whose paycheck comes from a mainland office while the actual work happens in Puerto Rico. That silence means the general rule, not a special exception, controls that case.

If your job genuinely has no fixed location at all, freelance or contract work with no set desk, the fallback rule in section 911 takes over: your tax home becomes your regular place of abode in a real and substantial sense. Live in Puerto Rico and work from there, and the fallback points to the same place the primary rule would.

Keeping a contemporaneous, day by day record of where you actually worked is what turns this analysis from a plausible story into documented fact. That is exactly the reconstruction problem One83 was built to remove: an automatic ledger of where you were, built from your calendar, so the record exists before an examiner ever asks for it.

Is passing the presence test the same as passing the tax home test?

No, and this is where a lot of otherwise careful people get tripped up. Publication 570 treats the presence test, the tax home test, and the closer connection test as three separate requirements, each with its own standard, and all three have to be met independently.

Hitting 183 days of presence in Puerto Rico tells you nothing, by itself, about where your tax home sits. You can clear the day count and still have an open tax home question, if a meaningful share of the days you actually worked, as opposed to simply were present, happened somewhere else. The two tests answer different questions: one counts where your body was, the other asks where your regular place of business is.

Does mainland work travel put your tax home at risk?

Occasional trips do not. A few days a quarter at a mainland office for a team meeting, a training, or a client visit does not relocate a regular place of business that otherwise sits in Puerto Rico. How work travel interacts with the presence day count is a related but separate question, worth reading alongside this one if travel is a regular part of your job.

The concern is a recurring pattern, not a trip. A significant, regular share of the year spent physically working from a mainland office, month after month rather than occasionally, can start to look like a second regular place of business. That is when the tax home question becomes genuinely closer.

Published guidance does not draw a bright line on exactly how much recurring mainland work is too much. Publication 570 and the section 1.937-1 regulation describe the general rule and the seafarer exception, but neither states a threshold, a day count, or a percentage for a hybrid remote arrangement split between Puerto Rico and a mainland office. If your work pattern is genuinely mixed between two locations on a recurring basis, this is an unsettled point. Get it in writing from a licensed tax professional before you file, rather than guessing at where the line sits.

Frequently Asked Questions

Does my employer being based on the mainland automatically break my Puerto Rico tax home?

No. Tax home tracks where you regularly do the work, not where your employer is incorporated or where payroll is run from. If you perform your job from Puerto Rico day to day, your tax home analysis starts from that location, not your employer's address.

What if my job has no fixed office at all?

Under section 911(d)(3) principles, if you have no regular or principal place of business, your tax home falls back to your regular place of abode in a real and substantial sense. For most fully remote workers who live in Puerto Rico, that fallback points to Puerto Rico.

Can I pass the presence test and still fail the tax home test?

Yes. The 183 day count, the tax home test, and the closer connection test are three separate requirements. Meeting the day count says nothing about where your tax home sits, and Publication 570 requires all three to be satisfied independently.

Does occasional travel to the mainland office put my tax home at risk?

Occasional trips for meetings or training do not, by themselves, relocate a regular place of business. The concern is a pattern: extended stretches of the year spent regularly working from a mainland location, which can start to look like a second regular place of business.

What should I keep on file to support a Puerto Rico tax home?

Keep evidence that your day to day work happens from Puerto Rico: your calendar and presence ledger, any home office documentation, and records of how much time, if any, was spent working from outside the island in a given year.

The bottom line

Tax home follows the work, not the paycheck. A mainland W-2 sitting alongside a Puerto Rico address is not, by itself, a problem. What matters is where you regularly perform the job. For most remote workers living and working in Puerto Rico, that is the same place, which satisfies the tax home requirement independently of the day count and the closer connection test. Keep a genuine, contemporaneous record of where the work actually happened. A running day ledger, the kind One83 keeps automatically from your calendar, speaks to both the presence test and, indirectly, to the tax home question, since it documents where you were when the work got done.
