How Do You Review Your Puerto Rico Day Count Before You File?

Before you file, reconcile your day-by-day record against travel records and flag any day you cannot corroborate. Here is how, and what to give your advisor.

How do you review your day count before you file?

You review it by matching your day-by-day record against records you did not write yourself, then listing every day that has no outside support. The goal is a count you can explain, not a count that reaches a number. This is the last checkpoint of the year, after the July checkpoint and before anyone prepares a return.

Do it while airline accounts, card statements, and calendars are still easy to pull. A gap you find in January can usually be filled. One you find during an examination usually cannot.

How do you reconcile your record against travel records?

Start with every trip off the island. For each one, find an independent record of the departure and the return. Airline records are the strongest. Card statements show where you spent money on a given day, which supports presence but does not prove it by itself.

Then check the rule you are counting by. Publication 570 counts a day as a day in a location if you are physically there at any time during the day. 26 CFR section 1.937-1(c)(3) states the same standard for days in the possession. A late arrival and an early departure are both days with presence in that place.

Finish with arithmetic. Count your Puerto Rico days, your US days, and your days elsewhere. The three should add up to the number of days in the year. If they do not, a day is missing or counted twice, and you want to know that before your advisor does.

Which days have no corroboration, and what do you do with them?

Look for days with no travel record, no transaction, and no calendar entry. A quiet week at home can leave almost no trace. That is normal. A stretch like that is not a problem in itself.

The trouble starts when an uncorroborated day sits next to a trip. If you flew out on the 3rd and your next record is the 9th, what happened on the 4th through the 8th? Write the answer in a note, with whatever supports it.

Do not change a day in your record to make the total work. Mark it as uncorroborated and tell your advisor. How an unsupported day is treated is a question for a licensed tax professional, and your job is to bring it to them whole.

How do edge days affect the count?

On edge days the rule decides, not your memory. Three come up most often.

Arrival and departure days. The any-time-during-the-day standard applies to both. Check the date on the actual record, not the date you remember.
Short transit through the US. Publication 570 says a day in the US of less than 24 hours, while traveling between two foreign places, is not a US day. A connection from a foreign country to Puerto Rico through the mainland is a different fact pattern. Check it against the text before you rely on it.
December 31 and January 1. A late flight can put a day in a different tax year than you expected. Confirm the local date on the record.

One edge case deserves its own flag. If you were in Puerto Rico and the United States on the same calendar day, published guidance is thin enough that what is settled and what is not is worth reading first. Put that day on your advisor list. Do not decide it alone.

Can days outside Puerto Rico still count, and what paperwork do they need?

Some days outside Puerto Rico can count toward your presence. Publication 570 and the regulation list the cases: qualifying medical treatment for you, or for a parent, spouse, or child you accompany, and days you could not return because of a declared major disaster or a mandatory evacuation.

Each has a paper trail to build before you file. For medical treatment, the regulation requires you to keep the patient and facility details, the physician's information, the treatment dates, payment receipts, and a signed physician certification. You must make them available within 30 days of a request. Gathering them in the spring is easier than gathering them in thirty days.

Publication 570 also allows up to 30 days of travel outside both Puerto Rico and the US to count, but only if your Puerto Rico days exceed your US days. That 30-day allowance does not help the 60-day minimum in the 549-day alternative. If you are leaning on it, work through the numbers with your advisor.

Does a passing day count settle your residency?

No. The presence test is one of three tests. You also must have had no tax home outside Puerto Rico and no closer connection to the United States or a foreign country than to Puerto Rico. Both of those are measured across the year, not only on the days you count.

So the review has a second pass. Ask whether anything changed during the year that touches your tax home, such as a new employer, a new office, or a business location. Ask whether anything you listed on forms, licenses, or registrations still points somewhere else. The guide on the three tests together walks through how they fit.

If your year included a move, Form 8898 may be part of your filing. The instructions for Form 8898 say it is required when your worldwide gross income is more than $75,000 and you take a position that you became or ceased to be a bona fide resident of a territory. It is filed separately from your return, by the Form 1040 due date including extensions. The penalty for failing to file is $1,000 unless there is reasonable cause. Whether it applies to you is a question for your advisor.

What should you hand your advisor?

Bring a package that lets them check your work without coming back to you for more.

Your day-by-day record for the full year, with each day marked Puerto Rico, US, or elsewhere
The reconciliation: which trips you matched, to which records
A short list of uncorroborated days, with your note on each
Medical or evacuation paperwork for any day outside Puerto Rico you want counted
Anything that changed your tax home or your ties during the year

Keeping this record by hand is the part people abandon by March. One83 builds it from your calendar, so the day-by-day record exists before anyone asks for it, and you spend the review checking it instead of writing it.

If an examiner is already asking questions, the task is different. That case is covered in documenting presence once an examination is underway.

What is the takeaway before you file?

Treat the review as a reconciliation. Match every trip to an outside record, mark the days you cannot support, handle the edge days by the text of the rule, and remember that the count is one test of three. Then give your advisor the whole picture, including the parts that are untidy.
