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. The count runs on taxable years, and the timing of your I-407 filing 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. Section 877A(a)(1) treats all property of a covered expatriate as sold at fair market value on the day before the expatriation date. 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). Hand the card back before you ever become a long-term resident and none of this machinery attaches to you.

Canada’s own departure tax runs in the other direction, charged when you leave Canada; coming home just restarts your Canadian tax residency. Different regime, different guide.

How does the 8-year clock actually count?

On taxable years, which is exactly where people get burned. 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, and the Form 8854 instructions restate it: at least 8 of the last 15 tax years, counting the exit year itself. The test counts a taxable year if you held the status at any point in it. A card approved in November makes that whole calendar year one of your 8. Nothing in the test measures months.

The clock doesn’t stop when the plastic expires. For tax purposes the status keeps running until it’s revoked or administratively or judicially determined to be abandoned (section 7701(b)(6)). A card forgotten in a Vancouver drawer still accrues counting years.

There’s 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). Helpful early, dangerous late.

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; the third is pure paperwork and it’s the one non-filers fail.

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 net-worth test is the quiet one. It’s never been indexed, so a paid-off house plus a grown RRSP can clear $2 million without anyone feeling rich. The certification test is the one that catches non-filers: 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 do a lot of work. First, an exclusion comes off the deemed gain: $910,000 for expatriations in 2026 (Rev. Proc. 2025-32, sec. 4.38; statutory base $600,000, indexed, per 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)). Second, property you owned before you first became a US resident is treated as having a basis of no less than its 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 IRS carves US real estate and US-business property out of this floor (Notice 2009-85, sec. 3.D).

Retirement accounts skip the deemed sale and 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 real 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. After the dust settles, 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 in this whole area. 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. Claiming treaty residency in Canada does opposite things depending on where your clock stands. Before year 8, a treaty-resident year with benefits unwaived stays out of your count and can hold you under the line. 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). Move home in October, keep the card “just in case”, file that year as a treaty resident of Canada, and you’ve expatriated in October with none of the planning done.

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 (Form 8854 instructions). Miss the form and section 6039G charges $10,000 unless you show reasonable cause. And the third covered test hides here: the compliance certification lives only on Form 8854, so a long-term resident who never files it has failed to certify and is covered by default (Notice 2009-85, sec. 2.A).

What should I do next?

Pull your green-card approval date and count the way 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. A count of 7 or fewer means the real decision is when the I-407 goes in, and the difference between December and January can be the entire deemed-sale regime. A count of 8 or more shifts the work to the tests, starting with the five-year certification, since any catch-up filing has to finish before the 8854 can be signed truthfully.
