Exit Tax by Country 2026: What You Pay When You Leave

Moving your tax residence to another country used to be a clean break. You left, you stopped paying taxes there, life continued. That model is disappearing across Europe and beyond. Belgium introduced a capital gains tax with an exit component on 1 January 2026. Norway eliminated its five-year deferral loophole in 2024. The Netherlands is exploring extended post-departure taxation of worldwide income. Even countries that have had exit taxes for years, like Germany and France, are tightening enforcement. The trend is clear: governments want their share of wealth built within their borders, whether or not you sell anything before you leave.

How exit taxes work

An exit tax treats your assets as if you sold them on the day before you changed tax residence. You haven't sold anything. You may have no cash to pay the bill. The government taxes the unrealised gain anyway, calculated as the difference between acquisition cost (or the value when you arrived, in some cases) and fair market value on departure. The logic: the gain accrued while you were a tax resident, so the country has a right to tax it before you leave.

The European Court of Justice has upheld the principle that member states can defend their tax base by taxing unrealised capital gains generated in their territory. Most EU/EEA countries offer deferral for moves within the bloc, which the ECJ requires as a proportionality measure. Moves to non-EU countries typically trigger immediate payment, sometimes with instalment options.

Belgium: the newest entrant

Belgium had no capital gains tax on shares held as part of "normal management of private wealth" until 31 December 2025. The new regime effective 1 January 2026 imposes a 10% tax on gains from financial assets (shares, crypto-assets, foreign currencies, certain insurance contracts), with an annual exemption of EUR 10,000 in net gains. Gains accrued before 1 January 2026 are grandfathered: the base cost is reset to the asset's value on 31 December 2025.

The exit tax component triggers when a Belgian tax resident moves abroad. Unrealised gains built up from 1 January 2026 onward are treated as if realised on departure. For moves within the EU, EEA, or to a country with a qualifying tax treaty, payment is automatically deferred for 24 months. If you don't sell the assets during those 24 months, the exit tax liability expires entirely. If you do sell within that window, the tax becomes immediately due. Moves to countries without a qualifying treaty require the taxpayer to post security for deferral.

For anyone who arrived in Belgium from 2026 onward, the acquisition value of financial assets is stepped up to their market value on the date of arrival. Pre-arrival gains are not taxed. This step-up provision is important for mobile professionals considering Belgium as a temporary base.

Norway: the loophole that closed

Norway's exit tax regime was restructured in 2024 to close what had become a well-known planning strategy. Before 2024, departing residents could defer exit tax on unrealised gains and, if they held the assets for five years without selling, the tax obligation lapsed. The strategy was obvious: leave Norway, wait five years, sell. Norway eliminated the five-year expiry and now requires the tax to be settled within twelve years of departure, regardless of whether the assets are sold. The rate is 37.8% on unrealised gains above a NOK 3 million exemption, with instalment payments available over the twelve-year period.

For founders and business owners with significant equity value, the practical impact is severe. A Norwegian resident who built a company worth NOK 50 million faces a potential exit tax liability of roughly NOK 17.8 million (37.8% of NOK 47 million after the exemption) upon moving abroad. That liability doesn't go away by waiting. It must be paid or secured over twelve years. Some affected individuals accelerated their departures in late 2023 before the new rules took effect, creating a brief but measurable spike in high-net-worth emigration.

Germany: no new law, but sharper enforcement

Germany's exit tax under Section 6 of the Aussensteuergesetz applies when a resident holding at least 1% of a corporation's shares moves abroad. The departure triggers a deemed sale at fair market value, with gains taxed at the standard 25% capital gains rate (Abgeltungsteuer) plus solidarity surcharge and, where applicable, church tax. For moves within the EU/EEA, an interest-free, indefinite deferral is available in instalments. Moves outside the EU/EEA generally require immediate payment, though tax treaty provisions can modify this.

No new legislation was passed in 2025, but tax authorities intensified scrutiny of outbound relocations, particularly for individuals with complex offshore holdings or opaque fund structures. Valuation disputes are the most common friction point: the Finanzamt's assessment of fair market value at the date of departure frequently differs from the taxpayer's, and these disagreements can take years to resolve.

France: the ten-year shadow that almost was

France's exit tax applies to individuals holding shares worth more than EUR 800,000 or representing more than 50% of a company's capital. The tax is levied at the 30% flat rate (prelevement forfaitaire unique) on unrealised gains at departure. The key mitigating feature: if you hold the assets for two years (for holdings under EUR 2.57 million) or five years (above that threshold) after departure without selling, the exit tax is waived. Returning to France also cancels the liability.

In October 2025, France's National Assembly Finance Committee adopted an amendment that would have required wealthy French nationals to continue paying domestic taxes for up to ten years after relocating to lower-tax jurisdictions. The full Assembly voted it down in November 2025 by a single vote. The proposal is dead for this parliamentary session, but similar measures have been introduced repeatedly since 2019, and the political support is growing. Anyone planning a departure from France should factor in the possibility that extended post-departure taxation could pass in a future budget cycle.

Other countries at a glance

Spain: Exit tax applies to residents of ten or more of the past fifteen years, on share holdings exceeding EUR 4 million (or EUR 1 million with 25%+ ownership). Rates range from 19% to 30% after a new top bracket was added above EUR 300,000 in gains. EU/EEA movers can defer for ten years. Moving to a jurisdiction Spain classifies as a tax haven triggers up to five years of continued Spanish tax on worldwide income.

Netherlands: Gains on "substantial interests" (5%+ company ownership) are taxed at departure: 24.5% on the first EUR 67,804 and 31% above that. EU/EEA movers receive automatic interest-free deferral until actual sale. A more aggressive proposal explored in early 2026 would extend Dutch taxation of worldwide income for five years after departure, but no draft legislation exists yet.

Austria: 27.5% on unrealised gains across all financial assets, with no minimum threshold. EU/EEA deferrals apply. One of the broadest exit taxes in Europe by scope, catching even modest portfolios.

Denmark: Applies to residents of seven or more of the past ten years, on share holdings with a market value of DKK 100,000 (approximately USD 14,000) or more. That threshold is the lowest in any jurisdiction with an exit tax, catching a far wider range of departing residents than systems designed for high-net-worth individuals.

United States: The US taxes based on citizenship, not residence, making its "exit tax" different in kind. Under Section 877A, citizens who renounce and meet any of three tests (net worth of $2 million or more, average annual tax liability exceeding approximately $206,000-$211,000 over the prior five years, or inability to certify full tax compliance) are "covered expatriates." All assets are deemed sold at fair market value, with gains above an approximately $910,000 exclusion (2026, inflation-adjusted) taxed at standard capital gains rates. Deferral is available with adequate security, but interest accrues. The State Department reduced the renunciation fee from $2,350 to $450 effective April 2026, but exit tax rules remain unchanged.

The mistake most people make

Exit tax planning is not something you do six months before moving. By then, the asset values are established, the departure date is approaching, and restructuring options are limited. Effective planning starts two to three years before departure: reviewing asset structures, considering whether holding vehicles should be in personal or corporate name, understanding the interaction between exit taxes and tax treaty provisions, and in some cases accelerating or deferring gains before the move.

The second common error is assuming that a deferral equals a waiver. In France, yes, if you wait long enough without selling, the exit tax disappears. In Norway, it doesn't. In Germany, EU/EEA deferrals are indefinite but remain a liability on your record that crystallises if you sell or if certain other triggering events occur. Each country's deferral mechanics are different, and treating them as interchangeable leads to expensive surprises.

Get a cross-border tax opinion from an advisor in both the departure and arrival country before committing to a move. The interaction between the exit tax regime, the destination country's treatment of arriving residents (step-up provisions, tax holidays for new residents, treaty relief), and the specific asset classes involved determines the actual cost. A move that triggers a six-figure exit tax liability in one scenario might be largely offset by treaty relief or a step-up in another. The details are everything.
