Most people picture giving up a green card as part of the move. Pack the house, fly to Japan, mail the card back once the dust settles. The immigration side is fine with that story. The tax side isn’t. In the tax code, the day your card stops counting is a specific date, defined in a specific way, and it moves more than one thing at once.
I’ve written about what the exit tax is and who it catches. This post is narrower: the calendar. How the years are counted, what the exit date actually is, and why the same decision can cost more or less depending on which side of December 31 it lands on.
How the 8-of-15 years are really counted
The exit tax only reaches a green card holder who is a “long-term resident.” The definition is arithmetic: a lawful permanent resident in at least 8 of the 15 tax years ending with the year the status ends. Under that line, handing back the card is paperwork. Over it, tests.
The arithmetic has a catch that isn’t in the statute’s headline. The count is in tax years, not anniversaries. Under the residency regulations, you’re a resident alien for a calendar year if you held the card at any time during that year. One day in December is a year. So is the year you give the card back, because you held it for part of that year too, and the 15-year window ends with it.
Put those together and the line arrives earlier than the phrase “eight years” suggests. Say your card was approved in November of year one. Year one counts. If you surrender the card in year eight, even on January 1, that’s your eighth tax year and you’re a long-term resident. To stay under, the status has to end by December 31 of year seven. For a November card, that’s a little over six years of actual holding. I couldn’t find an IRS example that spells this out, which is why I’m spelling it out.
There’s one subtraction. A year in which you were treated as a resident of Japan under the tax treaty, and didn’t waive the treaty’s benefits, doesn’t count toward the eight. That sounds like a lever. For a green card holder it’s mostly a trap, because taking that treaty position is itself treated as ending your residency for tax purposes. I covered the tie-breaker problem in the dual-residency post, and nothing here changes the advice: don’t touch it without a professional.
The exit date isn’t the day you leave
Here’s the part I’d underline if I could underline only one thing. For tax purposes, green card status doesn’t fade. The regulation says resident status “is deemed to continue” unless it’s rescinded or formally determined to have been abandoned. Move to Japan, stop visiting, let the card sit in a drawer for a decade, and the IRS still counts you as a permanent resident every one of those years. The clock keeps filling, and the filing obligation keeps coming.
So the exit date is one of four events, and the Form 8854 instructions list them. The day you file Form I-407 with a consular or immigration officer. A final administrative order finding you abandoned the status, or a final court order if you appealed. A final removal order. Or the day you start being treated as a resident of another country under a treaty, don’t waive its benefits, and tell the IRS. Whichever comes first.
For someone leaving on their own terms, that means the envelope. In the ordinary case, Form I-407 now goes by mail to a USCIS forms center. In-person filing at an embassy, a USCIS international office, or a port of entry is for urgent situations. And here’s a gap I ran into: the IRS wording about filing “with an officer” predates mail-in filing, and I couldn’t find guidance on whether the postmark or the receipt is the tax date. If your exit lands near a year-end, that ambiguity is worth a question to your advisor, a tracked envelope, and a copy of everything.
Two things that are not exit dates. A reentry permit protects your immigration status while you’re abroad, and it does nothing to the tax clock, because it’s neither a rescission nor an abandonment. I looked into one and haven’t applied. And the moving day itself means nothing to Section 877A. Not the flight, not the lease, not the shipping container.
What the exit year moves
Once you’re over the 8-of-15 line, the calendar stops being a gate and becomes a dial. Three tests decide whether you’re a covered expatriate. Two are pinned to the date.
The net worth test, $2 million and never indexed, is a snapshot of what you own on the expatriation date. Not the year, the day. A market that’s up or down a few percent on that day can be the difference between covered and not, for a household near the line. The gifting post covered how ownership can move before that snapshot. This post is about when the snapshot is taken.
The income tax test uses a window: your average annual federal income tax for the five tax years ending before the exit date, and the 2026 threshold is $211,000. Move the exit from December to January and the window shifts by a full year. A year with a big bonus, a stock sale, or a Roth conversion drops out or stays in depending on which side of New Year’s the envelope goes. Nobody at the moving company will tell you that.
Then the deemed sale. For a covered expatriate, everything is treated as sold at fair market value on the day before the exit date, with a $910,000 exclusion for 2026. That gain lands in your exit year. It’s a dual-status year, a Form 1040-NR with a Form 1040 attached for the resident part. Form 8854 goes with that return, by that return’s due date, and skipping it carries a $10,000 penalty on its own.
I’m not going to pretend there’s a formula for picking the year. The point is smaller. The exit date is a variable you control, and it feeds into the tests. Pick it with the tests in front of you, not the packing list.
Japan has its own clock, and it starts on arrival
The US side counts years of holding a card. The Japan side counts days of having a home. Under Japanese rules, you become a resident when you have a 住所 in Japan, your base of life, judged on facts. That’s the day you arrive to stay, not January 1 of that year.
For a foreign spouse there’s a softer landing. A non-Japanese citizen who has lived in Japan five years or less out of the past ten is a “non-permanent resident.” That status is taxed on Japan-source income, plus whatever foreign income is paid in or sent to Japan. Jay, arriving on a spouse visa, would likely fall into that category.
I wouldn’t. The non-permanent category requires not holding Japanese citizenship. As a Japanese citizen, I’d be taxed on worldwide income from the day my base of life moved, with no five-year grace. Japan also has its own exit tax, for people leaving with over ¥100 million in covered assets, and it applies only if you lived in Japan more than five years out of the previous ten. I haven’t had a Japanese address in over a decade. That clock would start from zero. It’s the mirror image of the US count, and the two don’t talk to each other.
What about the gap between the two? If I mailed the card in March and moved in June, I’d be a US nonresident from March and not a Japanese resident until June. I looked for guidance on how that in-between stretch is treated and found nothing concrete on either side, so I’ll leave it there as an open question rather than guess.
Putting the dates in order
For our household the first section of this post is history. Year eight is behind me. The 8-of-15 gate closed a while ago, and I’m leaning toward naturalizing, which would make the rest of this post irrelevant to me. That’s still undecided. If I ever do hand the card back, the question isn’t “which year keeps me under eight.” It’s “which year’s five-year window looks best” and “what’s on the balance sheet that day.”
Whichever side of the line you’re on, the sequence I’d write on the whiteboard is the same. Gifts first, completed and in the US, because a gift received after you’re a Japanese resident meets Japan’s gift tax. Then the exit date, chosen against the five-year window and the net worth snapshot, filed in a way you can prove. Then the move, which sets the Japanese clock. I’ve argued before that the US decision comes before the packing, and this is the concrete version of that argument.
If you’re under the line, count from the year your card was issued, treat every partial year as whole, and find the December 31 that matters. If you’re over it, the calendar is no longer about avoiding the regime. It’s about walking into it on the best possible day.
FAQ
My green card was approved in December. Does that year really count as a full year?
Under the residency regulations, yes. Holding the card at any time during a calendar year makes you a resident for that year. Verify your own count with a professional before you plan around it, but don’t assume December gives you a free year.
If I just stop renewing the card, does the tax clock stop?
No. An expired card is an immigration problem, not a tax event. For tax purposes your status continues until you file I-407 or the government formally ends it. The years keep counting and the filing obligation stays.
Does a reentry permit pause anything?
Not on the tax side. It preserves your immigration status during a long absence. Every year you hold the card, permit or not, is a year in the 8-of-15 count.
Can I choose an exit date in a different year from my move?
Yes, and that’s the whole point of this post. The exit date is set by when you file I-407 or when a treaty position starts, not by where you sleep. Both dates matter, on different sides of the ocean.
Does giving up the card early get me out of the Japanese inheritance and gift rules?
No. Those follow Japanese residency and nationality, not US status. The ten-year rule is a separate clock, and I’ve written about it on its own.
