Who Has to Prove Your Residency, You or the IRS?

Who has to prove your Puerto Rico residency?

There is no rule in the residency statute or regulation that puts the burden on you or on the IRS. Section 937 and 26 CFR 1.937-1 define who is a bona fide resident, and neither assigns a burden of proof. A separate statute, section 7491, can move the burden to the IRS in a court proceeding, but only when you meet conditions. What happens in a particular case depends on its posture, and that part is a question for your advisor.

This guide separates three things: what the text says, what section 7491 adds, and where published guidance stops.

What do the statute and regulation say about proving residency?

A bona fide resident is a person who meets three requirements in the tax year. Section 937(a) lists them: presence in the possession for at least 183 days, no tax home outside the possession, and no closer connection to the United States or a foreign country than to the possession.

26 CFR 1.937-1 fills in each requirement. The presence test has five alternatives, and the tax home and closer connection tests are separate requirements. Publication 570 restates them in plain language.

None of these texts says who must prove what. The definition tells you what qualifies. It does not say which side has to show it.

That silence is easy to misread. It doesn't mean the examiner must disprove your count, and it doesn't mean you must prove every day. It means the answer is not in these three documents, so any firm claim about who carries the burden needs a source outside them. This guide names the one statute that addresses burdens generally, and it labels the rest as unsettled.

Is there any documentation duty in the regulation?

There is one, and it's narrow. The regulation requires records for days counted as qualifying medical treatment. For each treatment you must prepare or obtain, and maintain, records such as the physician's details and receipts of payment. You also need a signed certification from the physician. You must make these available within 30 days of a request from the IRS or the possession's tax administrator. Publication 570 repeats this rule.

That duty covers medical treatment days only. For every other day, the regulation and Publication 570 do not set out a record-keeping rule of their own. They do not say how a day of presence must be shown.

When can section 7491 move the burden to the IRS?

Section 7491 is the general burden-of-proof statute. Its rule is stated in section 7491(a): if, in a court proceeding, you introduce credible evidence on a factual issue, the IRS has the burden of proof on that issue.

The shift has conditions. It applies only if all of the following are true:

• You complied with the requirements of the Code to substantiate the item.
• You maintained all records the Code requires.
• You cooperated with reasonable requests from the IRS for witnesses, information, documents, meetings, and interviews.

Two limits matter for a residency position. First, the shift does not apply to an issue when another provision of the Code sets a specific burden on that issue. Second, for penalties on an individual, section 7491(c) gives the IRS only the burden of production in court. The burden of production is the duty to come forward with evidence first. That is a lighter duty than carrying the burden of proof.

Residency questions are factual: where you were on a given day, where you kept your home, where your connections were. That is the kind of issue section 7491(a) speaks to. The statute does not name Puerto Rico residency, so how the conditions play out for a given year is a matter for your advisor.

Does section 7491 apply during an examination?

The statute is written for a court proceeding. The text does not describe how the burden is treated while a return is still under examination, and the sources read for this guide do not resolve it.

Published guidance does not address this directly. Section 7491 covers court proceedings, but it is silent on the examination stage. If your year turns on this question, get it in writing from a licensed tax professional before you file or respond.

For what an examiner usually asks you to produce, see what an IRS residency examination asks for.

What depends on the posture of a case?

Several things are unsettled from the text alone, and this guide does not answer them:

• Which side carries the burden at each stage of a particular dispute.
• Whether your evidence is credible enough to count under section 7491(a) in a given case.
• How the closer connection test, which weighs many facts together, is evaluated when the facts point both ways.

Publication 570 says no single factor decides the closer connection test. It lists facts to weigh, including the location of your permanent home, where your family lives, where your personal belongings are, your banking, your driver's license, your voter registration, and the country you list on forms. How those facts add up is a judgment for your advisor, not a rule this guide can state.

Why do records matter whichever way the burden falls?

The conditions in section 7491(a) reward the same habits that help in any dispute: substantiating items, keeping records, and answering reasonable requests. A burden shift you can't qualify for does you no good.

The practical step does not depend on the legal answer. Build a day-by-day record as the year goes, not after a letter arrives. How to document presence for an audit covers what to keep. A record made at the time is easier to rely on than a reconstruction. One83 builds that record from your calendar so it exists before anyone asks for it.

Your Form 8898 answers matter too. Publication 570 says the answers in Part III help establish the jurisdiction to which you have a closer connection. See Form 8898, line by line for the filing year.

What is the short answer?

Settled: the residency statute and regulation assign no burden of proof. Section 7491 can shift the burden to the IRS in court, on credible evidence, if you substantiated, kept records, and cooperated. Unsettled here: how the burden works at examination and in your specific posture. Keep your records, and put the posture question to your advisor.

Frequently Asked Questions

Does the IRS have to prove I am not a bona fide resident of Puerto Rico?

Neither section 937 nor 26 CFR 1.937-1 contains a rule that says so. Section 7491 can move the burden on a factual issue to the IRS in a court proceeding, but only if you introduce credible evidence, substantiated the item, kept the required records, and cooperated with reasonable requests. Who carries the burden in your case depends on its posture, so ask your advisor.

Does section 7491 apply during an examination?

The statute speaks of a court proceeding. The text does not describe what happens at the examination stage, and published guidance read for this guide does not resolve it. If your year is under examination, ask your advisor how the burden is being treated.

Do I have to keep records of my days in Puerto Rico?

The only documentation duty spelled out in the regulation and Publication 570 is for days counted as qualifying medical treatment. Section 7491 also ties any burden shift to substantiation and keeping required records, which is a practical reason to keep a day-by-day record for every year.
