The Exit Tax Nobody Warns You About: What It Costs to Leave, Country by Country

Most "move abroad" advice obsesses over where you're going. The bigger surprise is often what your old country charges you on the way out. Here's the exit-tax map for 2026 — who actually pays, how much, and how to leave clean.

People spend months choosing a destination and almost no time on the tax their current country charges them simply for leaving. That's the wrong way round. For some people the exit bill is larger than anything they'll save abroad in the first few years, and it lands at the worst possible moment — while you're mid-move, with cash tied up in the assets being taxed.

The good news is that for most ordinary earners the exit tax is smaller than the panic suggests, and sometimes zero. The bad news is that for founders, investors and anyone holding appreciated assets, it can be very real. Knowing which camp you're in before you book a one-way ticket is the whole game.

What an exit tax actually is

An exit tax — also called a departure tax or, in the US, the expatriation tax — is a charge on the unrealised gains in your assets, triggered by the act of leaving. The country treats you as if you sold everything the day before you go, calculates the paper profit you'd have made, and taxes it. You haven't actually sold anything or received any cash, which is what makes it sting: it's a real tax bill on a hypothetical sale.

It isn't a wealth tax on what you own. It's a capital-gains tax on appreciation, brought forward to your departure date. And it usually triggers on one of two events: ceasing to be a tax resident (most countries) or, in the American case, renouncing citizenship.

Two things decide whether it touches you: what your country taxes on the way out, and whether you cross its thresholds. Those vary enormously.

The 2026 picture, country by country

A few patterns are worth pulling out of that, because they decide which group you're in.

The two broad regimes: Australia and Canada

Most countries aim their exit tax narrowly at large shareholders. Australia and Canada are the exceptions that catch ordinary people, because their rules sweep in your whole investment portfolio.

In Australia, ceasing tax residency triggers "CGT Event I1," a deemed disposal of all your assets except Australian real estate — so foreign shares, crypto and overseas holdings are treated as sold at market value, with the gain taxed at your marginal rate (up to 47%), though the 50% capital-gains discount still applies to assets held over a year. You can elect to defer by keeping the assets inside the Australian tax net, which suits you if you expect to sell later at a lower rate elsewhere. Canada works similarly: a deemed disposition of most property on emigration, though the gain is measured only from the value when you became resident, and Canadian real estate and registered accounts like RRSPs are spared.

If you're Australian or Canadian with an appreciated investment portfolio, this is the line item to model before you move, not after.

The United States is its own animal

The US is the only major country that taxes on citizenship rather than residency, so moving abroad doesn't end your obligation — only renouncing does. And renouncing is what triggers the exit tax.

It applies only to "covered expatriates," meaning you trip at least one of three tests: a net worth of $2 million or more, an average annual income-tax bill over roughly $211,000 across the prior five years, or a failure to certify five years of tax compliance on Form 8854. Clear all three and you walk away with no exit tax at all. Cross any one and the IRS treats your worldwide assets as sold the day before you leave, with the first $910,000 of gain (the 2026 figure) excluded. The trap most people miss: retirement accounts get no exclusion and are treated as an immediate taxable distribution. One piece of good news for 2026 — the renunciation fee itself dropped from $2,350 to $450 in April.

For long-term green-card holders, the same regime bites once you've held the card for eight of the last fifteen years. Handing it back in year seven can sidestep the whole thing.

Europe targets founders, not everyone

The European exit taxes — Germany, France, Spain, the Netherlands — are built for entrepreneurs and large investors, not salaried emigrants. Germany's Wegzugsteuer triggers on a shareholding as small as 1% of a company; France sets the bar at €800,000 of shares; Spain at €4 million. If you don't hold a substantial stake in a company, most of these won't touch you. If you do, the bill on a founder's equity can be enormous, and it's payable on a company you can't easily sell to raise the cash. Moves within the EU or EEA usually qualify for interest-free deferral, which is one quiet reason a founder might step to another EU country before going further afield.

The UK stands out for having no general exit tax at all — only a "temporary non-residence" rule that claws back gains if you come back within five years. Leave for good and there's no departure charge on your non-UK assets.

The trend is one direction: tighter

This is the part that should change your timing. Exit taxes across the developed world are being strengthened, not loosened. Norway tightened its rules in 2024. The Netherlands is openly exploring a German-style regime that would keep emigrants taxable for years after they leave, alongside a separate 2026 move to tax unrealised gains. And in October 2025, France's National Assembly came within a single vote — 132 to 131 — of adopting US-style citizenship-based taxation, which would have taxed French nationals wherever they lived. It failed this time. The direction of travel is unmistakable.

The lesson isn't to panic. It's that the cost of leaving a high-tax country tends to rise, so the option you have today may be more expensive or more restricted in a few years.

What this means for two people

A salaried professional with a pension, some index funds and no large company stake, leaving a typical European country, often has little or no exit-tax exposure — the thresholds are built for founders, and they don't cross them. Their planning is mostly about cleanly establishing the new tax residency, not about a departure bill.

A startup founder sitting on appreciated equity is the opposite case. For them the exit tax can be the single largest number in the whole relocation, and the move has to be sequenced around it: realising or restructuring before departure, using EU/EEA deferral, or timing the exit before a threshold year. The order matters — sort out what leaving costs before you fall in love with where you're going. It's the same logic behind choosing a residency before a passport: the expensive, irreversible step should be the one you plan first.

How to reduce the bill

The legitimate levers are timing and structure, and they're specific to your country. Leaving before you cross a residency-year threshold (the US green-card eight-year mark, Germany's ten-of-twelve, Spain's ten-of-fifteen) can take you out of the regime entirely. Using EU/EEA deferral turns an upfront bill into a charge only when you actually sell. Realising gains in a low-income year, or restructuring holdings before the clock starts, can shrink the taxable amount. Pairing the move with a low-tax destination like Kazakhstan's AIFC programme, and getting your banking set up outside your old system before you leave, both buy you flexibility on the other side. None of this is do-it-yourself territory once real money is involved — the rules are detailed and the mistakes are expensive — but knowing the levers exist tells you what to ask a professional for.

Common questions

What is an exit tax? A tax on the unrealised gains in your assets, triggered when you leave a country. It treats you as having sold everything the day before departure and taxes the paper profit.

Does every country have one? No. Many have none at all — the UK, the UAE, and most territorial-tax countries don't charge one. Among those that do, the rules and thresholds vary widely.

Does the US tax me just for moving abroad? Moving doesn't trigger the exit tax; renouncing citizenship does. But because the US taxes citizens worldwide, moving abroad alone doesn't end your filing obligations — only renunciation does, and that's the event the exit tax attaches to.

I'm a salaried employee, not a founder. Am I exposed? Often not. Most European exit taxes target substantial company shareholdings you probably don't have. The exceptions are Australia and Canada, whose deemed-disposal rules can catch ordinary investment portfolios.

Can I avoid it by just not telling them I left? No. Tax residency is determined by facts, financial information is shared between countries under common reporting standards, and undeclared departures create far bigger problems than the exit tax itself. The goal is to leave correctly and cheaply, not invisibly.

This is general information, not tax advice. Exit-tax rules are detailed, country-specific, and changing quickly, and the figures here are current as of June 2026. Your own country's rules — and the destination's — both matter. Take professional, jurisdiction-specific advice before you move money or residency.
