What Is an Exit Tax? A Guide for Nomads

An exit tax is a one-time charge a country imposes when you stop being its tax resident or give up citizenship, calculated as if you sold your worldwide assets at market value the day you leave. The United States taxes "covered expatriates" under IRC Section 877A on deemed gains above $910,000 (2026), but only if your net worth hits $2 million or your average tax bill exceeds $211,000. Canada applies a deemed disposition on most assets the day you emigrate, taxing 50% of the gain at your marginal rate. Australia uses CGT event I1 when you cease residency. Most countries let you defer payment until you actually sell, though some require security. The biggest trap is assuming the tax only applies when you sell - it can trigger on paper gains the moment you leave.

Leaving a country's tax system is rarely free. Several governments charge a tax on the way out, treating your unsold investments as if you cashed them in on your last day as a resident. This catches many nomads off guard because no money has changed hands.

The logic is simple from the tax authority's side. While you were a resident, your assets grew in value under their tax jurisdiction. If you leave before selling, they lose the right to tax that growth. An exit tax claws back that lost revenue by taxing the gain at the moment you depart.

Exit taxes vary widely by country. The US version targets only wealthy expatriates renouncing citizenship or long-term residency. Canada and Australia apply a broader "deemed disposition" to most departing residents. Spain, France, and others have their own rules aimed at large shareholdings.

This guide explains what an exit tax is, how it works with a concrete example, who it applies to, and the mistakes that cost nomads money. Exit taxes only matter once you actually become a non-resident for tax purposes, so timing your departure is everything.

How an exit tax works

An exit tax works by pretending you sold all your taxable assets at fair market value on the day before you stopped being a tax resident, then taxing the gain. This is called a "deemed disposition" or "mark-to-market" event. No actual sale happens, but the tax bill is real.

The mechanics follow three steps. First, the country fixes a departure date, usually the day you cease residency or formally expatriate. Second, it calculates the gain on each asset as if sold that day: market value minus your original cost. Third, it taxes that gain under its normal capital gains rules, often with an exemption threshold.

Most exit-tax regimes exclude certain assets and offer a deferral election. You can typically postpone paying until you genuinely sell, though some countries demand security for large amounts. Real estate located inside the country is usually excluded because it stays taxable there regardless.

Example: Carlos leaves Canada

Carlos, a Canadian citizen, emigrates to Portugal on March 1, 2026, severing his ties to Canada. He owns a stock portfolio worth CAD 500,000 that he bought for CAD 200,000. Canada deems he sold it on March 1 for CAD 500,000, producing a CAD 300,000 capital gain. Half of that gain, CAD 150,000, is added to his 2026 income and taxed at his marginal rate. Carlos never sold a single share, yet he owes departure tax. He can elect to defer payment until he actually sells, using Form T1244, filed by April 30, 2027.

The Canadian rule comes from the Canada Revenue Agency's guidance on dispositions of property for emigrants. Carlos must also file Form T1161 because his property exceeds the CAD 25,000 reporting threshold. Source: Canada Revenue Agency - Dispositions of property for emigrants, BDO - Canada departure tax.

How the US exit tax works

The US exit tax applies only to "covered expatriates" who renounce citizenship or give up long-term green card status, and it taxes deemed gains above an inflation-adjusted exclusion. Unlike Canada and Australia, the US does not tax ordinary residents who simply move abroad. It only triggers on formal expatriation.

You become a covered expatriate if you meet any one of three tests. Your net worth is $2 million or more on the expatriation date. Your average annual net income tax for the five prior years exceeds $211,000 for 2026 expatriations. Or you fail to certify five years of tax compliance on Form 8854. The $2 million net worth figure is fixed and not adjusted for inflation.

If you qualify, IRC Section 877A treats all your property as sold at fair market value the day before expatriation. The resulting gain is reduced by an exclusion amount of $910,000 for 2026, up from $890,000 in 2025. Only gain above that exclusion is taxed. A $10,000 penalty applies for failing to file Form 8854 when required.

Example: Priya renounces US citizenship

Priya renounces her US citizenship on June 30, 2026. Her net worth is $3.5 million, so she is a covered expatriate under the net worth test. Her investment assets carry $1.2 million in unrealized gains. The IRS treats them as sold on June 29, 2026. After the $910,000 exclusion, $290,000 of gain is taxable at capital gains rates. Her primary home in another country and her foreign salary do not change this calculation - the tax is on the paper gain in her portfolio.

Who an exit tax applies to

An exit tax applies to people leaving a country's tax net, but the trigger differs sharply by country, so your nationality and where you lived determine your exposure. There is no single global rule. You need to check the specific country you are leaving.

In Canada and Australia, the exit tax applies broadly to most tax residents who emigrate, regardless of wealth. When you cease residency, the deemed disposition fires automatically on your non-exempt assets. Australia uses CGT event I1, and residents leaving can choose to disregard the gain until actual sale instead. The threshold for being caught is residency itself, not a net worth test.

In the United States, only covered expatriates pay. An ordinary American moving to Mexico while keeping citizenship owes nothing extra on departure. The tax only applies to those renouncing citizenship or surrendering long-term resident status who also clear the wealth or income thresholds. This is a much narrower group.

In several European countries, exit taxes target large shareholdings rather than all assets. Spain, for example, taxes residents leaving with company shares above 4 million euros who lived in Spain for 10 of the prior 15 years. If you hold modest, diversified investments, many of these regimes will not reach you. The point is that exit-tax exposure is highly individual and depends on where you sit in each country's rules.

Common mistakes nomads make with exit taxes

The costliest exit-tax mistakes come from misunderstanding when the tax triggers and what assets it touches. These errors are avoidable with planning, but they catch nomads who leave on short notice without checking the rules first.

Assuming the tax only applies when you sell. The defining feature of an exit tax is that it taxes unrealized, paper gains. Carlos in the example above owed tax without selling a share. Treating departure as a non-event because you held your portfolio is the single most common and expensive error.

Forgetting the deferral election deadline. Most countries let you postpone payment until you actually sell, but only if you file the right form on time. Canada requires Form T1244 by April 30 of the year after departure. Miss it, and the full bill is due immediately even though you have no cash from a sale.

Ignoring reporting forms even when no tax is owed. Reporting thresholds are separate from tax thresholds. Canada requires Form T1161 once your property exceeds CAD 25,000, and the US requires Form 8854 for every expatriate. Skipping these triggers penalties regardless of whether you owe tax.

Confusing exit tax with ongoing residency rules. An exit tax is a one-time event tied to your departure date. It is separate from the day-counting tests that decide residency in the first place, such as the 183-day rule or the US substantial presence test. You can owe exit tax in your old country and still trigger residency in a new one the same year.

Leaving without establishing residency elsewhere. Departing one country without becoming resident somewhere new can leave you in a tax-residency gap that complicates the exit calculation and invites audit. Sort out your new tax home before you sever the old one.

How Staywise tracks this

Staywise (the visa compliance app for digital nomads) tracks the day counts that decide when you become, and stop being, a tax resident in each country. Exit taxes hinge on your departure date and your residency status, and Staywise's automatic day tracking gives you a clear, exportable record of when you were present in each country.

The app monitors 183-day thresholds across multiple countries at once and alerts you as you approach residency triggers, so you can time a clean departure rather than discovering a surprise residency after the fact. Passport details stay on your device for privacy, and only travel dates sync. The in-app AI assistant answers plain-English questions about residency timing, and you can export your travel history to PDF or CSV for an accountant handling your exit return. Staywise does not calculate exit tax itself - that is a job for a qualified tax professional - but it gives you the dated presence record that calculation depends on.

Frequently Asked Questions

What is an exit tax in simple terms?

An exit tax is a one-time charge a country imposes when you stop being its tax resident or renounce citizenship. It treats your investments as if you sold them at market value on your departure date, then taxes the gain - even though you have not actually sold anything. The idea is to capture the growth in your assets that happened while you lived under that country's tax system. Not every country has one, and where it exists, the trigger and the amount vary widely by nationality, wealth, and asset type.

Does the US charge an exit tax when you move abroad?

No. The US does not charge an exit tax simply for moving abroad while keeping your citizenship. The exit tax under IRC Section 877A only applies to "covered expatriates" who formally renounce US citizenship or give up long-term green card status. Even then, you must clear one of three thresholds: a net worth of $2 million or more, an average annual income tax above $211,000 for 2026, or failure to certify five years of tax compliance. An ordinary American living in Thailand owes no exit tax.

How much is the Canadian departure tax?

Canada's departure tax is not a flat rate. When you emigrate, Canada deems you to have sold most assets at fair market value, and 50% of the resulting capital gain is added to your income and taxed at your marginal rate. For example, a CAD 300,000 gain produces CAD 150,000 of taxable income. Canadian real estate, RRSPs, RRIFs, and registered pensions are excluded. You can elect to defer payment until you actually sell using Form T1244, filed by April 30 of the following year, though large amounts may require security.

Can you avoid paying an exit tax by deferring it?

You usually cannot avoid an exit tax, but most countries let you defer payment until you actually sell the asset. Canada offers a deferral election through Form T1244, and Australia lets departing residents disregard the gain until disposal. The US allows deferral of the mark-to-market tax in certain cases. Deferral postpones the bill rather than canceling it, and some countries require you to post security for large amounts. Missing the deferral deadline means the full tax becomes due immediately, so the election form matters as much as the tax itself.

Which countries have an exit tax?

Several countries impose exit or departure taxes, though the rules differ. The United States taxes covered expatriates under IRC Section 877A. Canada and Australia apply a deemed disposition on most assets when you cease residency. Spain, France, Germany, and the Netherlands have exit taxes that mainly target large shareholdings or wealthy departing residents. Many countries, including the UAE and most no-income-tax jurisdictions, have no exit tax at all. Because the rules are so country-specific, you should check the exact regime of the country you are leaving before you set a departure date.
