A Twelve Month Recordkeeping Cadence for Your Puerto Rico Day Count

Why does a recordkeeping routine beat a year-end reconstruction?

A good annual routine has four parts: capture your days every month, check your tax home and closer connection records every quarter, compare your running total mid-year, and archive everything at year end. This is a practical routine, not a requirement. Neither Publication 570 nor 26 CFR section 1.937-1 prescribes a schedule for keeping your day count.

A day count record is a day-by-day account of where you were, kept for each day of the tax year. Build it as you go. The presence test is measured over the whole tax year, and the tax home and closer connection tests apply during any part of the taxable year, according to paragraphs (d) and (e) of the regulation. A year rebuilt in March from memory is weaker than a year recorded in the month it happened. For the timing argument in detail, see why the timing of a day log matters.

The one place the published sources spell out a documentation duty is qualified medical treatment days. Publication 570 and paragraph (c)(4)(iii) of the regulation say you must prepare or obtain and maintain specific records, and make them available within 30 days of a request. Everything else in this routine is judgment, not a rule. For a fuller view of what to keep for an examination, start with that guide.

What do you capture every month?

Close out each month in the first week of the next. Flights, ferries, and card charges are still easy to match then.

The rules you are counting against come from the regulation. A day counts as a day in the possession if you were physically present there at any time during the day. A day counts as a United States day if you were physically present in the United States at any time during the day. Transit between two non-U.S. points that keeps you in the United States for fewer than 24 hours is not a U.S. day. The regulation's text also says that a day spent in both the United States and the possession is a day of presence in the possession. How that interacts with your own travel pattern is a point where published guidance is thin on documentation. If your year turns on it, get it in writing from a licensed tax professional before you file. The guide on how days are counted covers the mechanics.

A workable monthly pass has four steps:

1. Write down the count for each day: in Puerto Rico, in the United States, or elsewhere.
2. Match every trip against a source that is not your memory: an airline confirmation, a ferry receipt, or a card statement.
3. Flag any day you cannot match. Note it as a gap now rather than resolving it later from recollection.
4. Total the month and the running year, split into days in Puerto Rico and days in the United States.

Keeping this by hand is the part people drop by spring. One83 builds the day-by-day record from your calendar, so the record exists before anyone asks for it.

Which records support your tax home and closer connection?

Presence is one of three tests. The other two ask different questions and need different records.

The tax home test is met if you did not have a tax home outside Puerto Rico during any part of the year. Publication 570 describes your tax home as your regular or main place of business, employment, or post of duty. If you have no main workplace, it is the place where you regularly live. The closer connection test asks whether you had a closer connection to the United States or a foreign country than to Puerto Rico during any part of the year. Publication 570 lists factors such as the location of your permanent home, family, belongings, banking, driver's license, and voter registration, and the forms you file.

Because both tests look at any part of the year, a quarterly check makes sense. Four times a year, confirm that each item still points where you say it does:

• Your lease or ownership papers and a recent utility bill for the Puerto Rico home.
• Your driver's license and voter registration.
• Your main bank and card accounts and the address they hold for you.
• Your place of work, or the place you regularly live if you have no main workplace.
• The address on forms you file.

Save a dated copy of what you find. If something changes, write down the date it changed. No published source says how often to do this or which item carries the most weight, so treat the list as a prompt, not a checklist the IRS issued.

What should you do mid-year to check your running total?

Around the end of June, compare your running total to the way you plan to pass the presence test. The presence test is satisfied in one of five ways under the regulation. Four are counted in days, and they are the ones to watch on a calendar:

• Present in Puerto Rico at least 183 days during the tax year.
• Present in Puerto Rico at least 549 days over the three-year period, with at least 60 days in each year.
• Present in the United States for no more than 90 days during the tax year.
• Present in Puerto Rico for more days than in the United States, if your earned income in the United States stays within the limit the regulation cites (section 861(a)(3)(B)).

The fifth path is having no significant connection to the United States during the tax year. Paragraph (c)(1) of the regulation sets out all five. For the headline threshold, see the guide to the 183 day threshold.

The mid-year check is arithmetic. Count the days you have, count the days left, and see whether your plans leave room. If your plans leave you short, that is a conversation to have with your advisor now, while the rest of the year is still open.

What do you archive at year end, and for how long?

In the first weeks of January, close the year. Finalize the day count, make sure every gap is either resolved with a source or labeled as unresolved, and save a summary by month. Then put the underlying records in one place: travel confirmations, card statements, the quarterly snapshots, and a copy of the return you file.

For how long, IRS guidance on how long to keep records ties retention to the period of limitations. The default is 3 years. It is 6 years if you omit income that is more than 25% of the gross income shown on the return, and records should be kept indefinitely if you do not file a return. The same page says to keep copies of filed returns and notes that records can matter for other reasons, such as insurers or creditors. Which period applies to you is a question for your advisor. See also how long to keep day count records.

If you moved to or from Puerto Rico during the year, there may be an additional filing. The IRS page on Form 8898 explains who may need to file it and notes a $1,000 penalty for failing to file or for incorrect information, absent reasonable cause. Check the current form instructions for the threshold and details.

What does the whole routine look like in one pass?

Monthly: close out the days, match them to a source, and flag gaps. Quarterly: confirm your home, license, voter registration, banking, workplace, and filing addresses. Mid-year: compare your running total to the test you rely on. Year end: finalize, archive, and keep copies of what you filed. No published schedule requires any of it. It is a habit that makes the year provable on the day someone asks.

Frequently Asked Questions

Does the IRS require a monthly day count review?

No. Publication 570 and 26 CFR section 1.937-1 state the tests and the day counting rules but prescribe no schedule. The cadence is a practical routine. The only record keeping requirement they spell out is for qualified medical treatment days.

How often should you update your day count?

Often enough that the record is made close to the days it describes. Monthly is a practical interval for most travelers, and weekly works for people who move between Puerto Rico and the mainland often.

What should you do if you find a gap in a month?

Mark it as a gap and rebuild it now from travel and card records, noting that the entry was made later. Do not fill it from memory and present it as contemporaneous.

How long do you keep a year's day count records?

IRS guidance ties retention to the period of limitations for the return, generally 3 years from filing, with longer periods in some cases. Your advisor can confirm which period applies to you.
