Zero Percent: Where to Move if You Invest in Stocks or Crypto, and What Leaving Doesn’t Solve

Some 30 countries don't tax individuals' capital gains, and several openly court holders of stocks and bitcoin. The starting rule works in their favor: a gain on securities is in principle taxed in the country where you live on the day you sell. But it has expensive exceptions: exit taxes, dividend withholding, reclassification as a professional trader, U.S. citizenship. And all of it sits inside a transparency timetable that wraps up in 2027.

The Rule Everyone Dreams About

The OECD model tax treaty assigns the taxation of gains on stocks, bonds, and fund shares to the seller's country of residence. It provides two main exceptions: real estate and, in some treaties, substantial shareholdings. An investor who genuinely lives in a country with no capital gains tax on the day he sells therefore owes nothing on the gain, including, in principle, the portion that built up before he arrived. The entire market for investor relocation rests on that point.

Crypto takes the logic further: it has no issuer and no location, and almost no country withholds tax on it at the source. For its holders, residence is practically the only connecting factor.

Three things complicate the picture. The country you leave can tax the unrealized gain on your way out. Dividends remain subject to withholding in the country of the company that pays them. And the rule doesn't apply to Americans.

Americans First: What Doesn't Work, and What Does

The United States taxes its citizens and green card holders wherever they live. Moving to Dubai or Singapore changes nothing about the federal rates on long-term capital gains (0%, 15%, or 20%) or about the 3.8% net investment income tax, which foreign tax credits generally don't offset. The Foreign Earned Income Exclusion covers only earned income. To the IRS, crypto is property. Every swap of one token for another is a taxable disposition, and platforms have been issuing Form 1099-DA since 2025. One quirk survives for now: the wash sale rule, which bars repurchasing within 30 days a security sold at a loss, doesn't apply to crypto.

Three routes remain open.

Change states. Florida, Texas, Nevada, Wyoming, Tennessee, South Dakota, and Alaska have no income tax, and New Hampshire repealed its tax on interest and dividends in 2025. A Californian avoids up to 13.3% that way and a New Yorker more than 10%, provided the move is real, since both states audit fake departures closely. Washington State has no income tax but has taxed long-term capital gains since 2022, at 7% above roughly $270,000, with a higher bracket added in 2025.

Puerto Rico. It is the only place where a U.S. citizen can legally bring the tax on capital gains down to zero without giving up the passport. A bona fide resident's Puerto Rico-source income is exempt from federal tax, and the local law known as Act 60, successor to 2012's Act 22, exempts gains that accrue after the move. The conditions are strict: 183 days of presence, a tax home and closer connection on the island, the purchase of a residence, a $10,000 annual donation to local charities. Above all, gains built in as of the day you arrive remain taxable by the United States if the assets are sold within ten years. The IRS has been running an audit campaign aimed at these residents since 2021. Puerto Rico's legislature has also reworked the regime for new entrants starting in 2026, replacing the full exemption with a reduced rate — worth confirming with a Puerto Rico tax adviser before relying on the exact figures.

Renunciation. It triggers an immediate tax on unrealized gains, after an exclusion of roughly $910,000, for people whose net worth exceeds $2 million or whose average tax over the past five years tops about $200,000. For someone holding bitcoin bought cheap, it amounts to paying the whole bill up front.

Another trap hits Americans living in Europe. European funds and ETFs are PFICs in the IRS's eyes, subject to a punitive regime. Meanwhile, European brokers can no longer sell U.S. ETFs to retail clients, for lack of the disclosure document EU rules require. The American living in Lisbon or Berlin is therefore limited, in practice, to individual stocks or to an account kept open in the United States.

The Europe That Doesn't Tax, or Won't for Long

Switzerland exempts private capital gains on movable assets, crypto included, but the exemption comes with several trade-offs. Dividends are taxed at ordinary rates. Net worth, crypto included, valued at the official year-end rate, bears an annual cantonal wealth tax of 0.1% to nearly 1%. Staking and mining income is taxable. And the tax authorities can reclassify the investor as a professional securities dealer, in which case the exemption disappears and social security contributions are added. A federal circular lists five safe-harbor criteria: holding periods of at least six months, trading volume under five times the portfolio, gains making up less than half of income, no leverage, and derivatives used only for hedging. Zug, which turned its "Crypto Valley" into a brand, accepts payment of part of your taxes in bitcoin. Non-Europeans need a residence permit and, often, lump-sum taxation.

Belgium long exempted gains falling within the "normal management of private assets." That exemption is over: since January 1, 2026, a 10% tax applies to gains on financial assets, crypto included, with an annual exemption of around €10,000. Gains accrued before that date remain exempt. Speculative transactions are still taxable at 33%, dividends at 30%, and an annual tax hits securities accounts above €1 million.

Luxembourg exempts gains on securities held more than six months when the stake stays under 10%, and treats crypto the same way. Monaco has neither income tax nor capital gains tax, except for French nationals. The Netherlands doesn't tax realized gains but a deemed return on net worth, taxed at 36%. The Supreme Court struck the system down in 2021, and the reform meant to replace it keeps getting postponed, most recently to 2029.

Several countries exempt based on holding period. Germany taxes stocks at 25% plus the solidarity surcharge but fully exempts crypto held more than a year, which makes it, unexpectedly, one of the best regimes in the world for the patient holder. Portugal has applied the same exemption beyond 365 days since 2023 and taxes at 28% below that. The Czech Republic exempts stocks and, since 2025, crypto after three years up to a cap of CZK 40 million a year, Croatia after two years, Slovakia listed shares after one year. Slovenia applies a sliding scale that falls to zero after fifteen years. Bulgaria exempts gains on EU regulated markets and taxes the rest at 10%. None of these regimes requires leaving the European Union.

Then come the new-resident regimes. Italy's flat tax covers all foreign income and gains, except qualifying shareholdings sold during the first five years. Outside the flat tax, it raised the rate on crypto from 26% to 33% starting in 2026. Greece offers a €100,000 flat tax and exempts gains on listed shares held at under 0.5%. Cyprus exempts gains on securities and, for seventeen years, the dividends and interest of non-domiciled residents. Tax residence there can be acquired in 60 days subject to conditions, and the 2026 reform set crypto gains at a flat 8%. Malta doesn't tax its non-doms' foreign capital gains, even when remitted; separately, non-doms owe a €5,000 minimum tax once their unremitted foreign income tops €35,000 (with a spouse). The United Kingdom replaced non-dom status in April 2025 with a four-year exemption for foreign income and gains, reserved for those who weren't resident during the ten prior years.

Some countries are worth avoiding on this ground alone. Ireland taxes capital gains at 33% and ETFs at 41%, with a deemed disposal every eight years. Denmark taxes certain funds annually on a mark-to-market basis, at rates up to 42%. Spain goes up to 30% and adds a wealth tax plus a dedicated reporting form for crypto held abroad. Japan has long taxed crypto at up to 55% as miscellaneous income, and a reform is under discussion. India takes 30% with no offsetting of losses.

Outside Europe

The United Arab Emirates taxes neither the income, nor the capital gains, nor the dividends of individuals, and the 9% corporate tax doesn't apply to personal investments. Dubai set up a dedicated virtual assets regulator in 2022, and Abu Dhabi has an equivalent framework. Tax residence comes with 183 days of presence, or 90 days subject to conditions, and the treaty network is extensive. The country is a hard place to spend the summer, and life there is expensive. The main constraint, though, is getting the money out: Gulf banks, like European ones, demand a complete transaction history before accepting crypto-derived funds.

Singapore and Hong Kong don't tax capital gains or, for the most part, dividends. Both do tax the profits of anyone who trades as a business, based on criteria of frequency, holding period, and organization close to the Swiss ones. Both have tightened oversight of platforms: Singapore imposed a strict licensing regime in 2025, and Hong Kong passed a stablecoin law the same year. In both, getting a residence visa is the real hurdle. Malaysia doesn't tax individuals' gains on listed securities. Thailand has exempted for five years, starting in 2025, crypto gains realized on its licensed exchanges, while taxing foreign income brought into the country.

In Latin America, Panama, Costa Rica, Paraguay, and Uruguay tax on a territorial basis, and Uruguay adds an eleven-year exemption for new residents, rewritten in 2026 to require either 183 days of physical presence, about $2 million in real estate, or roughly $100,000 a year into a government-backed investment fund. One ambiguity rarely gets flagged: the "source" of a crypto gain realized from a couch in Panama City is clearly defined nowhere. El Salvador made bitcoin legal tender in 2021 and withdrew that status in a late-January 2025 reform tied to its IMF deal; whether its original capital-gains exemption for bitcoin survived that rollback is unclear. Georgia exempts individuals' crypto gains. The Cayman Islands, the Bahamas, and Bermuda tax nothing, but the cost of living there exceeds Geneva's. New Zealand, which has no general capital gains tax, nonetheless taxes crypto bought with the intent to resell, which covers most cases.

What the Country You Leave Holds On To

The exit tax. France taxes unrealized gains on holdings worth at least €800,000 or representing 50% of a company, with payment deferred for moves within the EU. Germany targets stakes of at least 1% and, since 2025, investment fund holdings with an acquisition cost above €500,000, a measure that lands squarely on large ETF portfolios. Spain targets portfolios above €4 million, the Netherlands stakes of at least 5%. Norway and Denmark apply harsh rules, and Canada treats departure as a deemed disposition of everything. Nearly all of these rules target securities, not crypto. The bitcoin holder is therefore, today, the most footloose investor in Europe, though nothing guarantees that will last.

Return and tail rules. The United Kingdom taxes gains realized abroad by anyone who comes back within five years. Spain treats nationals who move to a tax haven as residents for five years. Germany extends its taxing rights for ten years on moves to low-tax countries, and Sweden follows its former residents' Swedish shares for ten years.

Dividends. The country of the issuing company takes its withholding wherever the shareholder lives: 30% in the United States, reduced to 15% by treaty, 35% in Switzerland, more than 26% in Germany. A resident of a no-tax country has no local tax to credit that withholding against, so for him it becomes a final cost. That's why investors based in zero-tax countries favor accumulating funds domiciled in Ireland, which bear only 15% on the U.S. dividends they receive. Those same funds solve a second problem, the U.S. estate tax, owed above $60,000 by a nonresident alien who holds U.S. stocks directly.

The broker. Many brokers close the account of a client who changes country of residence. Make sure yours accepts residents of the destination country before you go.

The Other Direction: The European Who Moves to the United States

The United States grants no step-up on arrival. Anyone who becomes a U.S. tax resident, through a green card or the substantial presence test, is taxable on the entire gain at sale, including the part that accrued twenty years before they arrived. Canada and Australia do the opposite and reset basis to market value on the day of entry. The precaution is to sell your positions and buy them back before you land. It is often overlooked.

The End of Invisibility

The OECD's Crypto-Asset Reporting Framework sets up automatic exchange of data from platforms. The EU's DAC8 directive has applied since January 1, 2026, and the first global exchanges are planned for 2027. The UAE, Singapore, Hong Kong, and Switzerland have committed to take part, in 2027 or 2028 depending on the jurisdiction. Because the blockchain is public and permanent, a wallet identified once reveals its entire history.

None of this undermines a legitimate move abroad, but the practical consequence is twofold. The departure has to be real: home, presence, center of interests, tax residence certificate. And the sale has to come after the departure, with documentation. Someone who sells in January from Dubai while his family, his home, and his doctor are still in Lyon or Munich has, as far as the tax authorities are concerned, sold in Lyon or Munich.

So, Where?

For a European holding crypto for the long term, the simplest answer is often not to leave the EU at all: Germany, Portugal, the Czech Republic, Croatia, or Luxembourg exempt long holding periods with no exit tax to pay and no life to rebuild.

For a European with a large stock portfolio or the sale of a business on the horizon, Switzerland works if he accepts the wealth tax and keeps a passive investor's profile. Italy under the flat tax or Cyprus suits those who prefer the Mediterranean, and the UAE those who want the most radical option. In every case, calculate the exit tax first.

The active trader risks reclassification as a professional almost everywhere private gains are exempt. The UAE is one of the few jurisdictions where the question doesn't arise.

The American starts by choosing a state. Puerto Rico is mostly worth it for future gains rather than past ones. Renunciation is only for someone who has done the math and whose children aren't American, since, as the previous installment explained, a former citizen's gifts and bequests to U.S. persons are taxed at 40%.

In all of these configurations, losses offset nothing in a country that doesn't tax gains, and regimes change fast. Belgium scrapped its exemption, Portugal and the United Kingdom their preferential statuses, and Italy doubled its flat tax and then raised its crypto rate. Anyone who builds a life around a 0% rate has to accept that lawmakers can change it from one budget to the next.

Before You Go

The precautions come down to a few points.

• Calculate the exit tax and identify the tail rules that apply in the country you're leaving.
• Date and document the change of residence, and get a certificate from the destination country.
• Sell after you leave, not before, unless you're moving to the United States.
• Keep the complete history of your crypto transactions, because the bank will ask for it first, before the tax authorities do.
• Check where your broker stands and where your funds are domiciled.
• Make sure you actually want to live in the place you've picked.

A tax-free gain in a city you leave after eighteen months, followed by a return that triggers a re-taxation rule, costs more than the 30% you were trying to avoid.

A note on method: this article is general information, not tax, legal, or investment advice, and each cross-border move needs its own professional review. The U.S. figures cited above — the federal capital gains and net investment income tax rates, the treatment of crypto as property and Form 1099-DA reporting, the wash sale rule's exclusion of crypto, the no-income-tax states and New Hampshire's 2025 repeal, California's and New York's top rates, the expatriation tax's $910,000 exclusion and its net-worth and income thresholds, the PFIC and PRIIPs rules facing Americans in Europe, and the absence of a basis step-up on arrival — were checked against IRS and state sources current as of September 2026. Cyprus's 2026 flat crypto rate and Uruguay's revised residency thresholds were checked as well. The European and rest-of-world rates were cross-checked in a second pass against official tax summaries and current reporting, which refined three points: the Czech Republic's crypto exemption is capped at CZK 40 million a year, the fate of El Salvador's original bitcoin tax exemption after its 2025 legal-tender rollback is unclear, and Malta's €5,000 minimum tax is a separate rule triggered by unremitted foreign income above €35,000, not a condition of its capital gains exemption. Tax and crypto rules move quickly in every country named here and should be reconfirmed with a professional before you rely on them.
