You left America in 2016. The IRS still thinks you live there

Figures relate to tax year 2025-26 (UK) · 2025 (US)

People leave America and get on with their lives. The green card goes in a drawer, the expiry date passes, and nobody thinks about it again.

Immigration law and tax law part company at exactly that point. For immigration purposes the card may be long dead. For tax purposes you remain a resident of the United States until the status is formally given up or taken away.

That gap produces years of unfiled returns for people who genuinely believed they had left. Green card abandonment is the process that closes it, and doing it properly matters more than doing it quickly.

Key takeaways

• An expired green card does not end US tax residence.
• You remain taxable on worldwide income until the status formally ends.
• Form I-407 is the usual way to abandon it.
• Long-term residents face the same exit tax as citizens.
• Eight years out of the last fifteen makes you long-term.
• A treaty tie-breaker claim can itself end the status.
• Form 8854 is required of long-term residents too.

What is green card abandonment?

Green card abandonment is the formal surrender of permanent resident status, usually by filing Form I-407 with the immigration authorities. According to IRS guidance, your residence for tax purposes continues until that abandonment is recorded or the status is judicially revoked.

The card itself is only evidence of the status. Losing the card, letting it expire or moving abroad does not alter what you are, because the status is a legal condition rather than a document.

That is why so many people are caught. Everything about their life says they left, and the only thing that counts says they did not.

Why does an expired card still matter?

Because the tax rule keys off lawful permanent resident status, not off a valid card. Only green card abandonment changes that status. The expiry date on the plastic governs re-entry to the United States and nothing else.

So a card that ran out in 2018 leaves you a tax resident into 2026 unless something formally ended the status. The obligation to report worldwide income continued throughout that period.

Per the IRS, the status ends only on abandonment, rescission or administrative or judicial revocation. Time passing is not on that list.

Who is a long-term resident?

Anyone whose card was live across eight or more of the fifteen tax years that end with the year their status finishes. The years need not run consecutively, and holding the card for any part of a year counts as the whole year.

That counting rule catches people quickly. Someone who held a card from March 2012 to September 2019 has touched eight tax years despite holding it for seven and a half.

Long-term resident status matters because it brings the expatriation rules into play on green card abandonment. Below eight years you can walk away without any exit charge at all.

A worked example

The figures below are illustrative. They use round numbers so you can follow each step and substitute your own.

Ben is British, worked in New York from 2011 to 2018 on a green card, and moved home to Leeds. His card expired in 2021 and he has filed nothing since leaving.

He held the card across eight tax years, so he is a long-term resident. He is also still a tax resident today, because he never filed Form I-407.

That means seven years of unfiled American returns reporting his British salary, his pension and his ISA. It also means FBAR filings for every British account he has held.

If his net worth now exceeds $2 million, abandoning the card triggers the exit tax on his worldwide assets. Had he filed I-407 in 2018, none of this would exist.

What does Form I-407 do?

It records your green card abandonment, and the date it takes effect is what ends your tax residence. You can file it at a consulate or by post to the relevant immigration office.

The form itself is short and there is no fee. The consequence is permanent, and you cannot simply reapply for the card afterwards.

Keep the receipt or the stamped copy. It is the only proof of the date, and that date governs everything that follows on the tax side.

The two ways out compared

The table sets out what each route does. Only one of them actually stops the clock.

What is the treaty tie-breaker route?

Where you are resident in both countries, the treaty decides which one wins, and a green card holder living permanently in Britain will usually be treaty resident here. Claiming that position can end American tax residence without filing I-407.

The claim is made on a return with a disclosure attached, so it is not something that happens silently. It is a formal position you take and must be able to support.

There is a sting. For a long-term resident, making that claim is itself treated as an expatriating event, so it can trigger the exit tax exactly as abandonment would.

Does the exit tax really apply to green card holders?

Yes, where you are a long-term resident. On green card abandonment the rules treat you the same way as a citizen renouncing, with the same three tests and the same deemed sale.

Net worth of $2 million is the test that catches most people, and it measures worldwide assets rather than American ones. A British home and pension frequently carry someone across.

Our guide to the exit tax and Form 8854 covers the calculation. The route out differs but the charge is identical.

What about the certification test?

It applies to green card abandonment too, and it is the test most holders fail. You must certify five years of American tax compliance, and somebody who stopped filing when they left has none of those years.

So a person with modest assets can still become a covered expatriate purely through unfiled returns. The exit tax then applies to a position that would otherwise have produced nothing.

Fixing the filings before abandoning is therefore the order of operations. Our guide to streamlined filing covers the catch-up route most people need.

Is streamlined filing available?

Usually yes, where the failure to file was not wilful. The foreign offshore procedures suit someone living in Britain and carry no penalty, which makes them the obvious route before abandoning the card.

The eligibility turns on non-wilfulness rather than on the amounts involved. Someone who genuinely believed an expired card ended everything usually fits that description comfortably.

Timing matters. The programme closes to you once the IRS makes contact, so acting before any letter arrives preserves the option.

What if you want to keep the card?

Then skip the green card abandonment entirely and treat yourself as an American taxpayer in full. That means worldwide income, FBAR, Form 8938 and the PFIC rules on any British funds you hold.

Keeping a card you no longer use is an expensive way to preserve an option. The annual compliance cost usually outweighs the value of a status you are not exercising.

Our guide to green card holders in the UK covers what the ongoing position looks like.

Does abandoning affect future US travel?

After green card abandonment you become an ordinary foreign visitor, so a British citizen uses the visa waiver scheme like anyone else. The card gave you a right of residence and that right ends.

Abandoning does not bar you from applying for a visa later or even for another green card. It is not a penalty and carries no adverse immigration consequence of its own.

What it does end is the ability to live there without applying again. Treat the decision as final for planning purposes.

What happens to US assets you keep?

They stay inside the American system as the assets of a non-resident. American dividends face withholding, American property keeps its own reporting, and the estate exemption falls to $60,000.

That estate figure is the one people miss. A retirement account and a share portfolio left behind in America can carry a real exposure on death.

Our guide to US estate tax for UK investors covers the thresholds and the treaty relief available.

How long does the process take?

Filing the form is quick, often a matter of weeks for the receipt. The tax clean up behind it takes far longer, particularly where several years need rebuilding from scratch. Most green card abandonment cases run six to twelve months end to end.

Allow six to twelve months from first looking at it to being fully clear. The streamlined submission alone needs three years of returns and six years of FBARs.

There is no deadline forcing your hand, which is precisely why people let it drift for years. Each year of drift adds another year of filings.

What if you are under eight years?

Then the exit charge never arises and the whole exercise becomes administrative. You file the form, bring any outstanding returns up to date, and the position closes without a deemed sale of anything.

That makes the year count the first thing to establish. Somebody at seven years has a materially easier route out than somebody at eight, and the difference can be a single tax year.

Where you are close to the line, the timing of the abandonment is worth planning rather than leaving to chance.

Does a conditional green card count?

Yes. A two year conditional card held through marriage or investment is still lawful permanent residence, and those years count towards the eight year test exactly as a full card would. The rules draw no distinction between the two.

People often discount those early years because the card felt provisional. The tax rules draw no distinction between conditional and permanent cards.

Count from the date the original card was issued rather than from any later replacement.

What about the years you were not living there?

They still count. The eight year test looks at how long you held the status, not at how long you spent in the country, so years abroad with the card in a drawer count fully.

That is the detail that turns a short American posting into long-term resident status. Three years working there followed by five years of drift reaches the threshold.

It is also why green card abandonment gets harder the longer it is left.

Do you need to file for the years in between?

Yes, for every year you held the status. Those returns report worldwide income on the same basis as a citizen, with foreign tax credits for the British tax you paid.

In practice most produce little or no American tax, because British rates are higher and the credits absorb the liability. The cost is the preparation rather than the tax.

Our guide to the foreign tax credit covers how the relief works.

Does it affect a spouse or children?

Only where they hold their own status. A green card is personal, so your abandonment does nothing to a spouse or child who holds a card in their own right.

Each person files their own form and runs their own eight year count. Families often find the answers differ, because cards were issued at different dates.

Children who became American citizens through the process are in a different position entirely, and would need to renounce rather than abandon.

How to handle it

1. Establish the exact date your green card was issued.
2. Count how many tax years you have held the status.
3. Check whether that reaches eight of the last fifteen.
4. Work out which years of returns and FBARs are outstanding.
5. Bring those filings up to date before abandoning anything.
6. Value your worldwide assets against the $2 million threshold.
7. File Form I-407 and keep the dated receipt.
8. File Form 8854 with the final return for that year.

Mistakes and penalties we see with green card abandonment

The first is assuming an expired card ended the status. Immigration and tax run on different rules, and only one of them cares about the expiry date.

The second is filing I-407 before fixing the returns. The certification test then fails and a straightforward exit becomes a covered expatriation.

The third is making a treaty tie-breaker claim without realising it is an expatriating act for a long-term resident. People reach for it as the simple option and trigger the charge instead.

The fourth is forgetting Form 8854 after abandoning. The form closes the tax relationship and the I-407 does not.
