A handful of countries impose no capital gains tax on individuals: Monaco, Belgium, Switzerland, Singapore, Hong Kong, New Zealand, the United Arab Emirates, the Cayman Islands, and the Bahamas. Countries without capital gains tax are not, however, countries without tax. Each of these jurisdictions collects revenue through stamp duties, VAT, wealth taxes, customs duties, or property transfer fees, and several attach conditions to the capital gains exemption itself. More importantly for American readers: US citizens and green card holders owe federal tax on worldwide capital gains no matter where they live, so relocating does not, on its own, shrink a US tax bill.
Monaco
Monaco abolished personal income tax in 1869 under a sovereign order signed by Prince Charles III and has never brought it back. Individuals residing in Monaco pay no tax on capital gains, wealth, or land, and dividends paid by Monégasque companies to shareholders are also untaxed. One bilateral exception matters: French citizens who became Monaco residents after January 1957 remain liable for French income tax under an agreement between the two countries.
Belgium
Belgium does not tax capital gains on shares, bonds, or other financial assets when an individual sells them as part of ordinary management of a private portfolio. Whether your activity counts as “normal management” or professional speculation is the whole question. If Belgian tax authorities conclude you were trading as a business, gains are taxed at 33 percent plus a municipal surcharge. Trading frequency, position sizes relative to your wealth, and the use of borrowed money to fund purchases are the factors that trigger reclassification. Occasional long-term investors rarely face problems. Day traders and heavy users of leverage do.
Switzerland
Capital gains on privately held securities — stocks, bonds, ETFs, cryptocurrency — are exempt from federal income tax in Switzerland under Article 16(3) of the Federal Direct Tax Act, and the cantons follow the same approach for private investors. The line between a private investor and a professional securities dealer is firm, and crossing it means gains are taxed as ordinary income at progressive rates that can exceed 40 percent in some cantons.
The Federal Tax Administration’s Circular No. 36 sets safe-harbor criteria for keeping private investor status. The main ones: you hold securities for at least six months before selling, your total annual transaction volume stays below five times the value of your portfolio at the start of the year, and your realized capital gains represent less than half of your net income. Missing one criterion does not automatically reclassify you, but it invites scrutiny. Meeting all of them keeps the gains tax-free.
Switzerland’s cantons also impose an annual wealth tax on the net value of your assets, which is a separate cost from any tax on gains at sale.
Singapore
Singapore does not impose a capital gains tax. Gains from selling shares, financial instruments, and investment property are treated as non-taxable capital receipts by the Inland Revenue Authority of Singapore (IRAS). The capital-versus-revenue distinction again applies: if IRAS decides you were buying and selling with a profit-seeking motive rather than holding investments, those gains become taxable business income. Trading frequency, your reasons for buying and selling, your financial capacity to hold assets long-term, and actual holding periods all feed the analysis.
Real estate is where Singapore gets expensive for foreigners. A foreigner buying residential property pays an Additional Buyer’s Stamp Duty of 60 percent of the purchase price or market value, whichever is higher. Sellers who dispose of residential property within four years of acquisition also face a Seller’s Stamp Duty of 4 to 16 percent depending on the holding period. There is no capital gains tax, but transaction costs on property can easily exceed what a capital gains tax would have been.
Hong Kong
Hong Kong has no capital gains tax, no dividend tax, and no tax on individual interest income. The territory operates on a strict territorial basis: only profits arising in or derived from Hong Kong are subject to Profits Tax, and investment gains on capital assets fall outside the tax net even when locally sourced. Repetitive buying and selling can be reclassified as trading profits and taxed at the standard Profits Tax rate, but the threshold for reclassification is relatively high for individuals who are not running a trading business.
New Zealand
New Zealand has no general capital gains tax. Gains on shares and other financial assets held for investment are not taxed. Residential property is the exception. Under the bright-line test, gains on residential land sold within two years of acquisition are taxable as income. The bright-line period was reduced from ten years back to two years for property disposed of on or after July 1, 2024. A property used as the owner’s main home during the holding period is excluded.
United Arab Emirates
The UAE does not levy income tax on individuals. Personal investment gains, including profits from selling stocks, bonds, or real estate, are not taxed at either the federal or emirate level. When the UAE introduced a 9 percent corporate tax in 2023, it carved out personal investment income. A natural person is only subject to the corporate tax if they conduct a business or business activity in the UAE with total turnover exceeding AED 1 million (roughly $272,000) in a calendar year. Wages, personal investment income, and real estate investment income do not count toward that threshold. The UAE also charges 5 percent VAT on goods and services.
Cayman Islands
The Cayman Islands have no income tax, no capital gains tax, and no corporate tax. Under the Tax Concessions Law, the government can issue formal undertakings guaranteeing that no future tax legislation will apply to a specific entity or approved investment for up to 30 years. The guarantee covers any tax on profits, income, gains, or appreciation that might be enacted in the future, which is a real hedge against policy change.
The Bahamas
The Bahamas funds its government through customs duties on imported goods and stamp duties on legal instruments like property conveyances, mortgages, and leases rather than through income or capital gains taxes. There is no tax on investment profits for individuals, and compliance requirements are minimal compared to most countries, with annual registration fees replacing complex income reporting.
Why Zero Capital Gains Tax Is Not Zero Tax
Every jurisdiction on this list collects revenue through other channels, and the alternative taxes can be substantial. Singapore’s 60 percent stamp duty on foreign property purchases is the most dramatic example, but the pattern is universal. The UAE charges VAT. The Bahamas levies customs duties on nearly everything imported to the islands. Monaco’s cost of living and real estate prices extract wealth through market forces rather than tax rates. Switzerland’s cantons impose annual wealth taxes on your net assets.
Policies also change. Malaysia used to appear on lists like this one, and introduced a capital gains tax on unlisted shares effective March 2024. Any relocation built around a zero-tax rule carries the risk that the rule shifts after you arrive.
US Citizens and Green Card Holders Still Owe Federal Tax
This is the section most articles about tax-free countries skip past. The United States taxes its citizens and permanent residents on worldwide income regardless of where they live. Moving to Singapore or the UAE does not reduce a US capital gains tax bill by a dollar.
The Foreign Earned Income Exclusion does not help. It lets qualifying expats exclude up to $132,900 of earned income in 2026, but the IRS defines foreign earned income as wages, salaries, and professional fees for personal services performed. Profits from selling stocks, real estate, or other investments are not personal services income and do not qualify.
The Foreign Tax Credit is equally useless in zero-tax countries. The credit offsets US tax with taxes already paid to a foreign government. If the foreign country charges nothing on your gains, there is nothing to credit. Your full US capital gains liability remains.
Higher-income taxpayers also face the 3.8 percent Net Investment Income Tax on the lesser of net investment income or the amount by which modified adjusted gross income exceeds $200,000 for single filers or $250,000 for married couples filing jointly. NIIT applies to capital gains, dividends, interest, rental income, and royalties. Even where a foreign tax credit eliminates regular capital gains tax, the NIIT usually survives, because the credit generally cannot offset it.
Currency creates a further trap. The IRS requires gains to be calculated in US dollars using exchange rates on the purchase and sale dates. An asset that held steady in local currency can produce a taxable US gain if the dollar weakened between those two dates.
Reporting Foreign Assets to the US Government
Americans living in tax-free countries face two overlapping foreign asset reporting requirements, and the penalties for ignoring them can wipe out any tax benefit.
The Report of Foreign Bank and Financial Accounts (FBAR), filed as FinCEN Form 114, is required when the combined value of all your foreign financial accounts exceeds $10,000 at any point during the calendar year. That includes bank accounts, brokerage accounts, and any account where you have signature authority. Non-willful failure to file carries a penalty of up to $10,000 per violation, adjusted for inflation. Willful violations carry a penalty of up to 50 percent of the highest account balance during the year or $100,000, whichever is greater.
Form 8938, the Statement of Specified Foreign Financial Assets required under FATCA, is separate. For US taxpayers living abroad, filing thresholds are higher than for domestic filers: $200,000 at year-end or $300,000 at any point during the year for single filers, and $400,000 at year-end or $600,000 at any point during the year for married filing jointly. FBAR and Form 8938 have different thresholds, different filing destinations, and independent penalties. You may need to file both.
Over 100 jurisdictions now participate in the OECD’s Common Reporting Standard, which automatically shares financial account information between tax authorities. A bank in Singapore or the UAE is almost certainly reporting your account balances and income to the IRS through that framework.
The Exit Tax for Renouncing US Citizenship
Some people considering a move to a tax-free country eventually think about renouncing US citizenship to escape worldwide taxation. Congress anticipated that. Section 877A of the Internal Revenue Code imposes an exit tax on “covered expatriates,” treating all their assets as sold at fair market value on the day before expatriation and taxing the resulting gains.
You become a covered expatriate by meeting any one of three tests: net worth of $2 million or more, average annual net income tax liability over the five preceding years above an inflation-adjusted threshold, or inability to certify five years of tax compliance. The deemed-sale rule includes a base exclusion of $600,000 of gain, adjusted annually for inflation since 2008.
You must file Form 8854 to report the expatriation, with a detailed accounting of every asset you own. Covered expatriates who defer the tax must waive treaty benefits and post adequate security with the IRS. Section 2801 imposes a separate tax on US citizens and residents who receive gifts or inheritances from covered expatriates, which limits your ability to pass wealth back to family in the US after you leave.
Establishing Tax Residency in a Zero-Tax Country
Claiming the benefits of a tax-free jurisdiction requires becoming a tax resident there. The most common standard is the 183-day rule: spend more than half the calendar year in the country to be treated as resident for tax purposes. Immigration authorities track this through entry and exit stamps, airline records, and digital border systems.
Physical presence alone is not always enough. Many countries also apply a “center of vital interests” test that looks at where your family lives, where your primary home is, where your economic activity is concentrated, and where you take part in social and community life. If your spouse and children live in the US while you spend 184 days a year in Dubai, neither country may treat you the way you expected.
Financial barriers vary. Monaco has no published minimum investment requirement, but banks routinely expect a deposit of at least €500,000 to €1,000,000 before issuing the attestation letter immigration authorities require as proof of financial self-sufficiency. UAE golden visa programs require property investments or business income above specified thresholds. Singapore’s Global Investor Programme requires a substantial business track record and investment commitment. Professional fees for international tax attorneys, immigration lawyers, and local advisors add up on top of the qualifying amounts.
Getting residency wrong has real consequences. If your new country does not accept you as a tax resident, your home country may keep claiming full taxing rights on your worldwide income. Documentation like lease agreements, utility bills, and local financial accounts is not optional. Fraudulent residency claims can trigger back taxes, penalties, and in serious cases criminal prosecution for tax evasion.
