Hurricane Evacuation Days and Your Puerto Rico Presence Test

What Happens to Your Presence Count During a Hurricane Evacuation?

A day you spend on the mainland because a hurricane forced you out of Puerto Rico doesn't automatically count against your presence test. Publication 570 and its underlying regulation, 26 CFR 1.937-1, build a specific exception for exactly this situation: days you leave, or cannot return, because of a federally declared major disaster or a mandatory evacuation order.

That protection is narrower than "a hurricane happened while I was gone." It has a trigger, a measured window, and a documentation burden that falls on you. This guide walks through what actually qualifies, how the protected days are counted, and what to keep in case an examiner asks.

What Triggers the Exception: a FEMA Declaration or a Mandatory Evacuation Order?

Two separate triggers can protect the days you spend away from Puerto Rico. You only need one of them to apply.

The first is a Federal Emergency Management Agency notice of a federal declaration of a major disaster, published in the Federal Register. The trigger is that Federal Register notice itself, not the storm's landfall date and not a governor's or mayor's own local declaration. Publication 570 is explicit that the protected window runs from the disaster the notice describes, so the date on the notice is the date that matters for your count.

The second is a mandatory evacuation order in effect for the geographic area where your main home in Puerto Rico is located. This trigger doesn't depend on a FEMA declaration at all. If your municipality or region is placed under a mandatory evacuation order, days you spend away because of that order are protected on their own terms, according to 26 CFR 1.937-1.

You can be covered by one trigger without the other. A storm that produces a mandatory evacuation order for your area but never draws a federal major disaster declaration still protects your evacuation days. The reverse is true as well.

How Long Does the Protected Window Last?

The two triggers run on different clocks. Mixing them up is the most common way people miscount.

The FEMA disaster declaration protects a fixed 14 day period. 26 CFR 1.937-1 ties that window to the Federal Register notice date, so mark that date and count 14 days forward. Days you're away beyond that window, even if the disaster's effects are still visible, fall back outside the exception unless a mandatory evacuation order also covers them.

The mandatory evacuation order has no fixed cap. It protects every day the order remains in effect for your home area, whether that's four days or four weeks. What matters is the order's own start and end date, not how long you personally chose to stay away. What counts as a day of presence sets out the baseline day counting rules this exception sits on top of.

Does an Excluded Day Still Count as a Day in Puerto Rico?

Yes, and this is the part people underestimate. The regulation doesn't simply set the day aside as neutral. A protected disaster or evacuation day is treated as a day of presence in Puerto Rico, even though you were physically on the mainland.

A protected disaster or evacuation day is a day counted toward your Puerto Rico presence total, not a day removed from consideration. That distinction is what makes the exception valuable: it's an affirmative credit toward 183 or 549, not merely a way to avoid a penalty for being away.

How Do Disaster Days Interact With the 183 Day and 549 Day Tests?

The presence test gives you two routes. You can be present in Puerto Rico for 183 days during the tax year, or you can use the three year alternative: present for 549 days across the tax year and the two immediately preceding tax years, with at least 60 days of presence in each of those three years, per 26 CFR 1.937-1.

Disaster and evacuation days credited under this exception add toward whichever route you're using. They aren't tracked on a separate side ledger, and they don't require you to pick one test or the other in advance. If a hurricane forces you off island for nine days that fall inside the FEMA window or a mandatory evacuation order, those nine days still count toward your 183 or 549 total the same as a day you spent standing in San Juan.

How Does This Exception Compare to the Medical Days Exception?

The disaster and evacuation exception isn't the only named exception to the ordinary day count. Publication 570 also protects days spent outside Puerto Rico for a qualifying medical condition affecting you or a family member. Our companion guide on qualified medical treatment days covers that exception's own narrower rules.

Both exceptions share the same structure. You're physically outside Puerto Rico, but the day is credited as present because a specific, provable reason kept you away. Neither exception is a general excuse for being off island; each one is defined narrowly, tied to a specific trigger, and expects you to document that trigger if it's ever questioned.

What Should You Keep as Proof You Were Evacuated?

The presence test is verified from your own records, not from the general public's memory that a named storm occurred. Keep three things for any period you plan to claim under this exception.

First, the trigger itself: the FEMA notice and its Federal Register citation if you're relying on the disaster declaration, or the text and effective dates of the mandatory evacuation order if you're relying on that trigger instead. Second, your own travel records for the period: boarding passes, ferry tickets, or similar dated proof of when you left and when you returned. Third, anything that ties your presence on the mainland to that specific window, such as dated lodging receipts or communications.

Documenting your presence for an audit covers the fuller recordkeeping standard this exception sits inside. Keeping this kind of record by hand, across a hurricane season with multiple storms, is the part most people let slide by the second or third evacuation. One83 builds that ledger from your calendar automatically, so the record already exists if an examiner ever asks for it.

Frequently Asked Questions

Do hurricane evacuation days count against my Puerto Rico presence test?

No. Publication 570 and 26 CFR 1.937-1 provide that days you are on the mainland because you left, or could not return, during a FEMA declared major disaster's 14 day window, or during a mandatory evacuation order covering your home area, are treated as days of presence in Puerto Rico, not as days against you.

Does the 14 day disaster window start when the hurricane hits or when FEMA declares a disaster?

It starts when the Federal Emergency Management Agency's notice of a federal declaration of a major disaster is published in the Federal Register, not on the date the storm made landfall or the date local officials issued their own declaration.

Is a mandatory evacuation order capped at 14 days like the disaster window is?

No. The disaster declaration exception runs for a fixed 14 day period, but the mandatory evacuation exception covers every day the evacuation order remains in effect for the geographic area where your main home is located, however long that turns out to be.

What if I left Puerto Rico before a disaster was formally declared?

The exception is written around the FEMA declaration and the evacuation order, not around your personal timing. If you left early and no declaration or evacuation order ever covered that period, those days are not automatically excluded, so keep records of exactly when the declaration or order took effect and compare it against your own dates.

Do I still need to keep proof if my evacuation seems obviously covered by a well known hurricane?

Yes. The presence test is verified from your own contemporaneous records, not from general knowledge that a storm occurred. Keep boarding passes, the FEMA declaration date, and, if one applied to your area, the evacuation order itself.

The Bottom Line

A hurricane evacuation doesn't have to cost you a day toward your presence count. The rule exists for precisely this situation, but it only protects days that fall inside the FEMA 14 day window or a genuine mandatory evacuation order covering your home area. Outside those triggers, ordinary day counting rules apply. It pays to know what counts as a day and what the 183 day threshold requires before the next storm season puts the question in front of you.
