Form 8898, Line by Line: Filing the Year Your Residency Begins or Ends

Who Has to File Form 8898?

Two things have to be true in the same tax year: your worldwide gross income has to be $75,000 or more, and you have to become or cease to be a bona fide resident of a U.S. territory, Puerto Rico, the U.S. Virgin Islands, Guam, the Commonwealth of the Northern Mariana Islands, or American Samoa, according to the Instructions for Form 8898. Miss either condition and the form isn't required for that year.

The $75,000 figure is measured per person, not per household. The instructions specify that a spouse's income is not included when you calculate your own $75,000 threshold, and each spouse who independently clears the threshold files a separate Form 8898. Only one spouse crosses $75,000 in worldwide gross income? Only that spouse files.

Form 8898 also is not an annual filing. It applies once, to the specific tax year the change happens. A move to Puerto Rico that starts in June triggers a Form 8898 for that year only, assuming the income threshold is met, not for every subsequent year you remain a resident.

Part II of the form asks for the exact date your residency began or ended, so you need to be able to state that date with confidence. Reconstructing it after the fact, from memory, old plane tickets in a drawer, and calendar invites you half remember, is the hard way to do this. An automatic day ledger, which is what One83 builds from your phone's calendar as you go, keeps that date and the surrounding day count on hand before the form ever asks for it.

When and Where Do You File Form 8898?

The due date for Form 8898 matches your Form 1040, including any extension you file. No separate deadline to track.

Where it goes is the part that trips people up. Form 8898 is mailed on its own, to Internal Revenue Service, 3651 S. IH 35, MS 4301 AUSC, Austin, TX 78741. It's not attached to your Form 1040, and it doesn't go to whatever address your return uses. Two separate pieces of mail, two separate destinations, same due date.

That separation is exactly why the form gets missed. A preparer who only handles the 1040, or a filer who assumes one envelope covers everything, can file a complete and accurate return and still owe a $1,000 penalty, because Form 8898 never went out the door on its own.

What Does Form 8898 Ask, Line by Line?

Part I, General Information, sets the frame. Line 1 states the tax year and whether you became or ceased to be a bona fide resident that year. Lines 3a and 3b report your current year worldwide gross income and your 3-year average, the numbers behind the $75,000 filing trigger.

Part II, Presence Testing, gets specific. Line 4 asks for the exact date bona fide residence began or ended, the same date the year-of-move rule below hinges on. Lines 5 through 8 report the days you were present in the territory versus the United States, whether you maintained a significant connection to the United States, and any U.S.-source earned income for the year.

Those lines are where you report the result of whichever presence test path you actually used. Publication 570 and the underlying regulation lay out four ways to satisfy the presence test: 183 days in the territory during the year, 549 days across the current year and the two before it with at least 60 days in each of those three years (see the site's guide to the 549 day alternative if that's your path), no more than 90 days in the United States for the year, or having no significant connection to the United States at all. Haven't worked out which of these applies to your year? The site's overview of the presence, tax home, and closer connection tests is the place to start before you fill in Part II.

Part III, Closer Connection, and Part IV, Income Sources, round out the form. They're also the two parts the year-of-move rule changes the most, covered next.

Why Do Parts III and IV Change in the Year You Move?

The year residency begins or ends is a split year: part nonresident, part bona fide resident, and the regulation gives that year its own rule. For someone becoming a bona fide resident, the tax home test and the closer connection test only have to be satisfied for the last 183 days of that tax year, not the full year. The presence test doesn't get this shortcut: it still runs on its normal full-year rules.

In practice, that means you can have had a U.S. tax home or a closer connection to the United States earlier in that same calendar year, before the move, and still qualify, provided the last 183 days of the year clear both tests cleanly. The site's guide to the first partial year walks through the timing mechanics in more depth.

Part III's lines cover tax home status, the closer connection factors, your primary residence, where your immediate family lives, and homestead, investment, and income source details. All of it gets read against that last-183-days window in a move year rather than the calendar year as a whole. Part IV, line 32, reports gains from property dispositions, which matters here because a split residency year can change how a sale is sourced between the territory and the United States for tax purposes.

What Happens If You Don't File?

Filing is required, missing information, or incorrect information on Form 8898 carries a penalty of $1,000, unless you can show the failure was due to reasonable cause and not willful neglect.

Reasonable cause isn't a published checklist. It's a facts-and-circumstances determination, made case by case, and the IRS instructions don't spell out which specific situations qualify. That's a question for a tax professional familiar with territory residency filings, not something to guess at after the fact.

What you can control ahead of time is having the record the form actually asks for. Line 4 wants an exact date, and the presence test lines want an accurate day count for the year. A contemporaneous ledger, the kind One83 keeps from calendar data as the year happens rather than reconstructed from memory afterward, is the record that backs both an accurate filing and a reasonable-cause argument if a deadline still gets missed.

What Should You Do Next?

Form 8898 is narrow by design. It applies to one tax year, the year your bona fide residency in a U.S. territory begins or ends, and only if your worldwide gross income is $75,000 or more that year. It's due with your Form 1040 but mailed on its own to Austin, TX, and a missed or incomplete filing carries a $1,000 penalty with a reasonable-cause exception.

Before you fill in Part II, confirm which presence test path applies to your year. The presence, tax home, and closer connection overview is the place to check that first. Nothing here is a substitute for advice on your specific return.

Frequently Asked Questions

Do I file Form 8898 every year I live in Puerto Rico?

No. Form 8898 is a one-time notice for the specific tax year your bona fide residence begins or ends, not an annual filing. Once you have filed it for the year of the change, you do not file it again unless your residency status changes a second time, for example if you later leave and later return.

What if my worldwide gross income is under $75,000 the year I move?

You are not required to file Form 8898 for that year. The $75,000 worldwide gross income threshold is the sole trigger tied to income. If you do not meet it, the form is optional, though filing it anyway can help establish a documented record of the date your status changed.

Can I attach Form 8898 to my Form 1040?

No. The instructions are explicit that Form 8898 is mailed separately to the Austin, TX service center address, not attached to your income tax return or sent to the address you use for your Form 1040.

What counts as reasonable cause for filing late?

The IRS does not publish a fixed list. Reasonable cause is a facts-and-circumstances standard showing the failure to file was not due to willful neglect. A tax professional experienced with territory residency filings is the right person to evaluate a specific late-filing situation, since this determination is made case by case.
