The phrase 'exit tax' has dominated US wealth-migration headlines in 2026, fuelled by proposals in blue states and viral social-media claims. The reality is more nuanced: no state has enacted a true exit tax, but four jurisdictions enforce residency-tracking mechanisms that can produce similar financial consequences for high earners who relocate. Meanwhile, the federal expatriation tax—codified under IRC §877A—remains the only genuine exit levy in US law, applying to citizens and long-term green-card holders who renounce status.
This matters because the rhetoric has outpaced the statute. Founders, executives and retirees researching interstate or international moves encounter conflicting narratives: panic-driven posts warning of imminent wealth confiscation, and official guidance that describes only existing domicile rules. Below we map what the law actually says, which states impose the strictest residency tests, and how the federal expatriation regime compares.
United States
At the federal level, IRC §877A imposes a mark-to-market exit tax on 'covered expatriates'—individuals with net worth above $2 million, average annual income-tax liability exceeding $201,000 (2024 threshold, inflation-adjusted), or failure to certify five years of tax compliance. On the day before expatriation, all worldwide assets are deemed sold at fair market value; the resulting capital gain is taxed at prevailing rates, with a $866,000 exclusion (2024 figure). Deferred-compensation items, including unvested stock options and certain retirement accounts, face a 30 per cent withholding tax unless treaty relief applies.

No state has replicated this structure. California, New York, New Jersey and Massachusetts instead rely on 'safe harbor' residency tests that presume continued tax liability unless the departing resident severs all statutory ties—domicile address, driver's licence, voter registration, professional licences, and in some cases the location of a spouse or dependent children. California's Franchise Tax Board, for example, applies a nine-factor test; taxpayers who retain a California property, even as a rental, or spend more than 45 days in-state during the year of departure risk being classified as part-year or full-year residents, triggering state income tax on worldwide earnings. New York's 'statutory residency' rule deems anyone who maintains a permanent place of abode and spends more than 183 days in the state to be a resident, regardless of declared domicile.
In practice, high earners who sell equity or exercise stock options in the year they leave face combined federal and state marginal rates approaching 50 per cent in California (37 per cent federal + 13.3 per cent state) or 47 per cent in New York (37 per cent + 10.9 per cent). The 'exit tax' label is a misnomer—these are residency-continuation rules—but the cash impact can exceed $1 million on a $5 million liquidity event. Audit risk is elevated: California's residency-audit unit has expanded staffing by 20 per cent since 2023, and New York's Department of Taxation and Finance now cross-references E-ZPass records, mobile-phone geolocation data, and credit-card transactions to verify day counts.
Canada
Canada does not impose an exit tax on citizens who relocate abroad, but it does levy a 'departure tax' on deemed disposition of property when an individual ceases to be a tax resident. Under subsection 128.1(4) of the Income Tax Act, taxpayers are treated as having disposed of most capital property—publicly traded shares, private-company equity, real estate outside Canada used for non-personal purposes—at fair market value on the day before departure. The resulting capital gain is taxable at the individual's marginal rate (up to 27 per cent federally, plus provincial top rates ranging from 10.5 per cent in Saskatchewan to 20.5 per cent in Nova Scotia, for combined peaks near 48 per cent).
In April 2026, a viral Facebook post falsely claimed that Canada had implemented a new 'exit wealth tax' on high earners. Fact-checkers at AFP confirmed no such legislation exists; the confusion stemmed from a 2024 op-ed by a corporate executive suggesting that Canada consider an exit levy to stem brain drain. The Canada Revenue Agency has not proposed changes to the departure-tax regime, and no parliamentary bill has been tabled.
Principal residences, Canadian real estate held for personal use, RRSPs, TFSAs and certain pension accounts are exempt from deemed disposition. Taxpayers may elect to post security in lieu of immediate payment, deferring the tax until actual sale—but interest accrues at the prescribed rate (currently 6 per cent annually). For a founder with $3 million in unvested private equity, the deemed-disposition tax can exceed $700,000, payable within 120 days of departure unless security is posted.
Australia
Australia imposes a departure tax on certain visa holders and citizens leaving the country, but the term refers to two distinct levies. The Passenger Movement Charge—a $60 fee collected at airports and seaports—applies to all outbound travellers and is scheduled to rise to $70 in July 2026, according to a May 2025 budget announcement. This is an administrative fee, not a wealth tax.
For tax residents who cease residency, Australia applies a capital-gains-tax (CGT) event under section 104-165 of the Income Tax Assessment Act 1997. Individuals are deemed to have disposed of certain assets—primarily shares in non-Australian companies and rights or options over such shares—at market value on the date residency ends. Australian real property, assets used in carrying on a business through a permanent establishment in Australia, and certain employee share schemes are excluded. The deemed gain is taxed at marginal rates up to 47 per cent (including the Medicare levy).
Unlike Canada, Australia does not permit deferral by posting security; the tax is due in the return for the year of departure. However, if the individual becomes a resident again within five years and has not actually disposed of the asset, they may choose to disregard the earlier CGT event. For a tech executive relocating to Singapore with $2 million in US-listed stock, the departure CGT can approach $500,000, assuming a 50 per cent gain and the top marginal rate.
Japan
Japan's exit tax, introduced in 2015 and expanded in the 2024 tax reform, applies to individuals who have been tax residents for at least five of the past ten years and hold securities and derivatives valued at ¥100 million or more (approximately $670,000 at May 2026 exchange rates). Upon departure, these assets are deemed sold at market value, and the resulting capital gain is subject to Japan's 20.315 per cent aggregate rate (15 per cent income tax, 5 per cent resident tax, 0.315 per cent reconstruction surtax).
The December 2025 tax-reform proposal, reported by Table.Briefings, includes a provision to triple the threshold to ¥300 million (roughly $2 million), effective April 2027. The change aims to reduce administrative burden on mid-level expatriates while retaining the levy on ultra-high-net-worth individuals. Payment may be deferred for up to five years if the taxpayer posts collateral or continues to file annual returns; if the individual returns to Japan within five years and has not sold the assets, the exit tax is reversed.
For a founder with ¥500 million in listed equity, the current exit tax is approximately ¥81 million. Under the proposed ¥300 million threshold, the taxable base would fall to ¥200 million, reducing the liability to ¥41 million—a 50 per cent cut. The reform has not yet passed the Diet; public comment closed in February 2026, and enactment is expected in the autumn session.
The 2026 exit-tax debate illustrates a recurring tension in the Libaros Freedom Score framework: jurisdictions with high tax burdens (dimension 1) often layer residency-tracking or departure-tax rules that constrain mobility (dimension 2). The US federal expatriation tax, Canada's deemed-disposition regime, Australia's CGT-event structure, and Japan's securities levy all impose one-time charges that can exceed 20 per cent of net worth. For individuals prioritising tax efficiency and geographic optionality, understanding these rules before triggering a liquidity event is essential. The rhetoric may be louder than the statute, but the cash consequences are real.
