Exit Tax by Country 2026: Who Actually Pays It

Exit tax by country: what leaving actually costs and how to plan for it

Last honest look at 2026 rules

Most countries don't have a formal exit tax at all. The clearest, best-documented regimes belong to the United States, Canada, and Australia, all three treat departure or citizenship renunciation as a deemed disposal, meaning your assets are treated as sold at fair market value the moment you leave, triggering capital gains tax on appreciation you haven't actually realized in cash.

The US version deserves the most attention here, not because it's the harshest in percentage terms, but because it catches more people than most founders expect. It's triggered by objective thresholds, not simply by being ultra-wealthy: a $2 million net worth test, a five-year average net tax test, or five years of tax filing non-compliance. A successful startup founder with valuable but illiquid equity can trigger covered expatriate status without feeling personally "rich" in any conventional sense.

This guide covers exactly how the US, Canadian, and Australian regimes work, how exit tax intersects with startup equity specifically, and what genuine planning looks like before you trigger any of this.

Key Takeaways

- The US, Canada, and Australia are the clearest, best-documented exit tax regimes, all three apply a deemed disposal on departure or renunciation; most other countries have no formal exit tax at all.

- US covered expatriate status is triggered by any one of three thresholds: $2 million net worth, a five-year average net tax above $211,000 (2026), or five years of non-compliant tax filing, not simply extreme wealth.

- The US exit tax exemption on unrealized gains is $910,000 for 2026, gains above that threshold are taxed as if the assets were sold the day before expatriation.

- Startup equity counts toward the net worth test and is subject to deemed disposal, meaning a founder can face a real tax bill on illiquid, unsold company shares with no corresponding cash event to pay it.

- Genuine planning, five-year filing compliance, threshold awareness, and timing relative to major liquidity events, needs to happen well before a citizenship or residency change, not as an afterthought once the decision is already made.

What an exit tax actually is

An exit tax operates on a concept called deemed disposal: when you leave a country (or renounce citizenship, in the US case), tax authorities treat your assets as if you sold them at fair market value the moment before departure, even if you didn't actually sell anything. This closes an obvious gap that would otherwise exist: without it, someone could accumulate substantial unrealized capital gains, move to a jurisdiction with no capital gains tax, and then sell everything tax-free. Exit tax rules exist specifically to prevent that.

United States: the most consequential regime

Covered expatriate thresholds

US exit tax applies specifically to individuals classified as covered expatriates, a status triggered by meeting any one of three objective thresholds:

1. Net worth of $2 million or more at the time of expatriation.
2. Average net income tax liability above $211,000 (2026 figure) over the five years preceding expatriation.
3. Failure to certify five years of US tax compliance, regardless of net worth or income level.

Note that only one of these three needs to be met. A founder without $2 million in liquid assets can still trigger covered expatriate status through the income tax threshold or through incomplete filing history, according to current threshold data from Bright! Tax's US exit tax overview.

The exemption and how the tax works

Covered expatriates face a $910,000 exemption (2026 figure) on unrealized gains. Gains above that threshold are taxed as though the underlying assets were sold the day before expatriation, at applicable capital gains rates, even though no actual sale occurred and no cash necessarily changed hands.

How founder equity counts toward net worth

This is the intersection most exit tax content, written for a general expatriate audience, doesn't address with enough weight for Atlasway's readers specifically: a founder's equity in their own company counts toward the net worth test, and it's subject to deemed disposal like any other asset. A founder holding substantial but illiquid startup equity, unlisted, unsold, potentially years from an exit event, can face a real, immediate tax bill on appreciation that exists only on paper, with no corresponding cash event to actually pay it.

When Priya, a US-citizen SaaS founder with meaningful equity in her own company, began seriously considering renouncing US citizenship in 2025 after several years of building a life abroad, her accountant's exit tax projection came as a real shock. Her company's most recent funding round valuation put her equity stake well above the $910,000 exemption threshold, meaning renunciation would trigger a substantial tax bill on unrealized, illiquid gains she had no way to access in cash without a sale or liquidity event she wasn't planning for years. The exit tax exposure, not the decision to relocate itself, became the deciding factor in her timeline.

Canada

Canada applies a departure tax: when you cease Canadian tax residency, most capital property is treated as disposed of at fair market value on that date, triggering capital gains tax on the deemed gain. This mirrors the deemed-disposal principle underlying the US regime, though Canada's mechanics, exemptions, and specific asset treatment differ in detail from the US framework.

Australia

Australia similarly applies deemed disposal on ceasing Australian tax residency: capital gains tax applies to unrealized appreciation on relevant assets as though they were sold at the point residency ends. As with Canada, the specific mechanics and available elections differ from the US system, but the underlying principle, don't let appreciation escape taxation simply by leaving, is consistent across all three regimes.

Countries without a formal exit tax

This is worth stating plainly: most countries do not have a formal exit or departure tax at all. The US, Canada, and Australia represent a genuine minority among global tax systems in applying deemed disposal on departure. For founders and remote professionals evaluating relocation from a country without such a regime, this specific concern simply doesn't apply, though it's always worth confirming your specific home country's rules rather than assuming based on general patterns.

How this intersects with company ownership

This is the connective thread between Atlasway's company-formation content and its tax-residency content, and it deserves explicit attention: startup and company equity is often the largest, least liquid asset a founder holds, and it's precisely the kind of asset that exit tax rules target through deemed disposal.

A founder with substantial equity in a Delaware C-Corp, for example, considering both a company restructuring and a personal citizenship or residency change should evaluate these as connected decisions, not separate ones. Atlasway's guide to Delaware LLC formation and broader company-formation content is worth reviewing alongside any exit tax planning, since your equity structure directly affects your exit tax exposure calculation.

Planning before you trigger these rules

Five-year filing compliance (US)

For US persons, maintaining five years of clean, compliant tax filing history is one of the three independent triggers for covered expatriate status. Confirming this compliance well before considering expatriation avoids triggering covered status purely through a filing gap, regardless of net worth or income.

Net worth and income threshold awareness

Understanding where you sit relative to the $2 million net worth threshold and the $211,000 five-year average net tax threshold (2026 figures) should happen well before any formal expatriation process begins, not as a surprise discovered mid-process.

Timing relative to major liquidity events

Because startup equity valuations can shift dramatically around funding rounds or exit events, timing a citizenship or residency change relative to these events matters enormously. A founder considering expatriation might face a very different exit tax calculation before versus after a major valuation-changing event.

Who needs to take this seriously (and who doesn't)

Needs to take this seriously

• US citizens or long-term residents considering renunciation who hold significant equity, whether liquid or illiquid, approaching or exceeding the covered expatriate thresholds.
• Founders with substantial startup equity that could push their net worth calculation above $2 million even without significant liquid assets.
• Anyone with gaps in US tax filing history considering expatriation, since non-compliance alone triggers covered status regardless of wealth.
• Canadian or Australian residents planning to cease tax residency with meaningful capital property holdings.

Doesn't need the same level of concern

• Founders and remote professionals relocating from countries without a formal exit tax regime, the vast majority of jurisdictions globally.
• Individuals well below the relevant net worth and income thresholds with clean, compliant filing histories.

Next steps

Before any decision involving citizenship renunciation or ceasing tax residency in the US, Canada, or Australia, get a genuine exit tax projection from a qualified advisor, factoring in your full asset picture, including illiquid company equity, not just liquid holdings. Atlasway's guide to tax obligations when moving abroad is a useful companion read, and our guide to CRS disclosure requirements covers the broader reporting landscape that intersects with any major residency or citizenship change.

Conclusion

Exit tax exists in only a handful of countries, but where it applies, particularly the US regime, it can catch successful founders who don't consider themselves wealthy in any traditional sense, simply because illiquid company equity counts toward the relevant thresholds. Understanding the $2 million net worth test, the $211,000 five-year income test, and the $910,000 exemption before making any citizenship or residency decision is essential, not optional, for anyone holding meaningful startup equity.

If exit tax exposure is a live consideration for your situation, the next step is a detailed projection from a qualified cross-border tax advisor well before you finalize any relocation or renunciation plans.
