Do I Owe US Exit Tax If I Give Up My Green Card and Move Back to Canada?

Usually no. The US exit tax under section 877A only reaches you if two things are both true: you were a long-term resident, meaning you held the green card in at least 8 of the 15 taxable years ending with the year you give it up, and you meet one of the three covered-expatriate tests. Plenty of people handing a card back are neither. I-407 timing can decide the whole question, sometimes by one month.

Does giving up a green card trigger the US exit tax?

Only if you’re a covered expatriate, and you can’t be one without first being a long-term resident. An “expatriate” includes any long-term resident who ceases to be a lawful permanent resident (section 877A(g)(2)(B)), and you’re “covered” only if you meet one of three tests under section 877(a)(2). Section 877A(a)(1) then treats all property of a covered expatriate as sold at fair market value on the day before the expatriation date. Hand the card back before you ever become a long-term resident and none of it attaches to you.

How does the 8-year clock actually count?

On taxable years. Section 877(e)(2) makes you a long-term resident once you were a lawful permanent resident “in at least 8 taxable years during the period of 15 taxable years ending with” the year your status ends, exit year included (Form 8854 instructions). A year counts if you held the status at any point in it, so a card approved in November makes that whole calendar year one of your 8. One carve-out: a year in which the treaty treated you as a Canadian resident, and you didn’t waive treaty benefits, doesn’t count toward the 8 (section 877(e)(2); Form 8854 instructions).

What makes you a covered expatriate?

Meeting any one of three tests in the year you expatriate (section 877A(g)(1)(A)). Two are about money: average annual net income tax over the 5 years before expatriation above $211,000 for 2026, or net worth of $2,000,000 or more on the expatriation date. The third is pure paperwork and it’s the one non-filers fail: without a certification of 5 years of US tax compliance on Form 8854 you’re covered at any net worth.

Test	2026 trigger	Indexed?	Source
Average annual net income tax over the 5 years before expatriation	More than $211,000	Yes, annually	IRC 877(a)(2)(A); Rev. Proc. 2025-32, sec. 4.37
Net worth on the expatriation date	$2,000,000 or more	No; the $2 million line hasn’t moved since 2008	IRC 877(a)(2)(B)
Certification of 5 years of US tax compliance, made on Form 8854	Failing to certify makes you covered at any net worth	n/a	IRC 877(a)(2)(C); Notice 2009-85, sec. 2.A

The $2 million line has never been indexed, so a paid-off house plus a grown RRSP can clear it without anyone feeling rich. On Form 8854 you certify under penalty of perjury that you met every US tax obligation for the 5 preceding years, and the IRS reads that as income tax, employment tax, gift tax, and information returns, plus paying what was owed (Notice 2009-85, sec. 2.A). Behind on any of it? Then catch up through the Streamlined procedure before you expatriate.

What does the exit tax actually hit if you’re covered?

On paper, nearly everything, all at once. The mark-to-market rule deems all your property sold at fair market value on the day before your expatriation date (section 877A(a)(1)), and “property” is measured with the federal gross-estate yardstick, so worldwide assets including Canadian real estate are in scope (Notice 2009-85, sec. 3.A). Two built-in reliefs cut it down: a $910,000 exclusion off the deemed gain for expatriations in 2026 (Rev. Proc. 2025-32, sec. 4.38), and a basis floor on property you owned before you first became a US resident, though not for US real estate or US-business property.

• The exclusion’s statutory base is $600,000, indexed (section 877A(a)(3)). Expatriated in 2025 and filing now? That year’s exclusion is $890,000 and the tax-liability trigger was $206,000 (Form 8854 instructions (2025)).
• The floor sets that basis at no less than fair market value on the day your US residency began, so pre-US appreciation stays out of the deemed gain (section 877A(h)(2)); the US real estate and US-business carve-out is the IRS’s (Notice 2009-85, sec. 3.D).

Retirement accounts run through their own machinery:

Asset	In the deemed sale?	Treatment at expatriation
Taxable brokerage, real estate (Canadian real estate included)	Yes	Deemed sold at fair market value the day before the expatriation date; the $910,000 exclusion applies (877A(a)(1); Notice 2009-85, sec. 3.A)
RRSP or RPP	No	Deferred compensation item. A Canadian payor generally makes it ineligible, and ineligible items are taxed as if you received the accrued benefit the day before expatriation (877A(c); Notice 2009-85, sec. 5)
IRA	No	Specified tax deferred account: treated as a distribution of your entire interest the day before expatriation (877A(e))
401(k) with a US payor	No	Can stay eligible: 30% withholding on later taxable payments once you give the payor Form W-8CE (877A(d)(1); Notice 2009-85, sec. 1)

If a bill lands, section 877A(b) lets you defer the tax asset by asset until you actually sell, with adequate security posted and a US agent appointed (Notice 2009-85, sec. 3.E). Deferral parks the bill rather than shrinking it. What RRSP withdrawals cost once you’re back in Canada is its own planning file.

Can timing get you out of the exit tax entirely?

Often, yes, and it’s the cheapest planning move available. End your LPR status while the count sits at 7 or fewer and you were never a long-term resident, so the covered-expatriate tests and Form 8854 never enter the picture.

Question	End LPR status in counting year 7 or earlier	End it in year 8 or later
Long-term resident?	No	Yes
Form 8854 owed?	No	Yes
Covered-expatriate tests applied?	No	Yes, all three
Deemed-sale exposure?	No	Yes, if any test is met
Section 2801 tail on future gifts and bequests to US persons?	No	Yes, if covered: recipients pay at the highest estate/gift rate above $19,000 a year in 2026 (IRC 2801; Rev. Proc. 2025-32, sec. 4.42(3))

The trap in the middle is the treaty. Article IV(2) of the US-Canada treaty breaks a residency tie by permanent home, then centre of vital interests, then habitual abode, then citizenship. Before year 8, a treaty-resident year with benefits unwaived stays out of your count. After year 8, the same claim pulls the trigger: under the final sentence of section 7701(b)(6), an LPR who commences to be treated as a Canadian treaty resident, doesn’t waive benefits, and notifies the IRS on Forms 8833 and 8854 ceases to be a lawful permanent resident for tax purposes, and for a long-term resident that cessation is itself the expatriation event (IRS, Expatriation tax). A citizen faces a different version of this, with no 8-of-15-year clock and the certification as the only lever: renouncing US citizenship from Canada.

What do you actually file in the exit year?

Start with the date. For tax purposes your residency ends on the earliest of the events in the Form 8854 instructions: filing Form I-407 with a US consular or immigration officer is the usual one, and a final administrative or judicial abandonment order, a removal order, or a treaty position with proper notice also qualify. Your initial Form 8854 then attaches to your income tax return (Form 1040 or 1040-NR) for the year that includes that date, due when the return is due. Miss the form and section 6039G charges $10,000 unless you show reasonable cause.

What should I do next?

Pull your green-card approval date and count as the statute counts: every calendar year you held the status at any point, minus any full treaty-resident year where you didn’t waive benefits. At 7 or fewer, the decision is when the I-407 goes in. At 8 or more, the work shifts to the tests, starting with the five-year certification, since any catch-up filing has to finish before the 8854 can be signed truthfully.
