Exit Tax

When you move abroad and give up your old tax home, some countries don’t simply wave goodbye. They treat your departure as a taxable event. The idea is that you might be leaving partly to avoid future tax, so the country wants its share of the value that built up while you lived there — before it loses the right to tax you.

In practice this usually targets unrealised gains. If you hold shares, a business stake, or other investments that have grown in value, an exit tax can treat them as if you sold everything on your last day of residency, then bills you on the paper profit. You may owe tax on money you haven’t actually received. Whether it applies, and to which assets, depends entirely on the country and often on how long you lived there, how large your holdings are, and where you’re heading next.

The catch people miss is that this is tied to changing your tax residency, not to your visa or your flight date. You can physically leave and still be on the hook if the country considers you resident. Or the tax can fire the moment it decides you’ve truly broken ties — something judged through tests like your centre of vital interests. Moving somewhere with territorial taxation doesn’t undo an exit tax you already owe the country you left. Some countries let you defer it (you pay later, when you actually sell), but the deferral can come with strings: keep filing, or post a guarantee.

Before you assume you’re affected — or safe — check your specific situation with the tax residency checker and read the official guidance for the country you’re leaving. This is general information, not advice; confirm with the official source or a qualified professional before you act.

Where you’ll meet this

• Planning to leave a country like Germany, France, Canada or the US while holding shares or a company stake, and discovering your departure itself can be taxed.
• Reading the small print on a country’s tax-authority website about what happens to your investments when residency ends.
• Sitting with a cross-border accountant who asks how long you lived there and what assets you hold before telling you whether a deferral is possible.
