Moving Abroad with Stocks: Tax Guide for German-Speaking Expats (2026)

You want to move abroad — and you have a brokerage account with stocks, ETFs, maybe a few solid buy-and-hold positions from the last decade. Before you pack the boxes, there is a painful truth: Germany and Austria tax your departure as if you had sold your entire portfolio on your last day in the country — even if you never moved a single share. This guide explains what happens at exit (§ 6 AStG / § 27 EStG), how Double-Taxation Treaties (DTAs) actually work, which six top destinations remain attractive in 2026, and what traps lurk when you try to take your portfolio with you. Updated May 2026 — including Portugal’s NHR sunset and Germany’s 2022 ATAD reform.

1. The Exit Trap — what really happens

Picture this: You have lived in Munich for 15 years and built a 700,000 euro portfolio of Apple, Microsoft, ASML and an S&P 500 ETF over the years. Initial cost basis: 250,000 euros. Unrealized gain: 450,000 euros. You deregister at the local town hall and move to Dubai — and at the moment your German residence ends, the tax office fictionally treats your portfolio as sold at fair market value. You have not earned a cent, but the tax office sends you a bill on a 450,000 euro phantom gain.

That is the core principle of exit taxation: unrealized gains accumulated under German (or Austrian) tax authority must not migrate abroad untaxed. Both countries apply the concept but in different ways — Austria captures essentially all capital assets, Germany only “substantial holdings” of 1 % or more in corporate entities. But: for ETF and small-holdings portfolios in Germany, the formal exit tax does not apply — the trap lies elsewhere, in the new tax regime of your destination country and in the DTAs.

Three effects you must understand before planning anything:

• Immediate assessment: tax falls due on market value at the day of departure — even without an actual sale.
• Deferral and return rules: both countries know mechanisms for deferral and refund, but only under strict conditions.
• Withholding-tax complexity: without a German or Austrian address you change the withholding-tax status of your portfolio, which on US stocks can mean an immediate 30 % instead of 15 % withholding.

2. Germany — § 6 AStG in detail

§ 6 of the Foreign Tax Act (Außensteuergesetz, AStG) has governed German exit taxation since 1972. It applies to natural persons who were unrestrictedly tax-liable in Germany for at least 7 of the last 12 years and at the time of departure hold at least 1 % in a corporate entity (§ 17 EStG). Classic cases: GmbH partners, family-business shares, larger AG holdings.

What gets taxed? The fictional gain on the shares at fair market value on departure day, at the personal income-tax rate (under the partial-income method 60 % is taxable for corporate shares) or for free-float positions at the flat 25 % capital-gains rate plus solidarity surcharge and possibly church tax. Example: GmbH share, cost basis 50,000 euros, market value 1 million. Unrealized gain 950,000. Of that, 60 % = 570,000 is taxable. At 42 % top rate plus solidarity ≈ 252,000 euros immediately due.

The 2022 ATAD reform — the most important change in 50 years. Until end of 2021: emigration to an EU/EEA country = permanent interest-free deferral until actual sale. Emigration to a third country = tax due immediately or installment plan over 5 years against collateral. Since 2022 a uniform rule applies to ALL departures (EU and third country alike): the tax is assessed immediately but, on application, can be deferred in 7 annual installments against security (with interest, but interest-free deferral possible in some cases). The old EU privilege has vanished — politically driven by the EU’s Anti-Tax-Avoidance Directive (ATAD).

Return rule: anyone who becomes unrestrictedly tax-liable in Germany again within 7 years (extendable to 12 on application) sees the exit tax retroactively waived. Conditions: no sale of the holding during the period abroad, no loss of the holding by inheritance or gift outside the EU, and the return must have been “seriously intended” from the outset.

The second trap is more subtle: even when § 6 AStG does not apply, an investor leaving Germany must complete a so-called final assessment. All preliminary flat-rate amounts (Vorabpauschale on accumulating ETFs), undistributed dividends and unused loss-offsetting buckets are reconciled at the cut-off date. Anyone holding a large loss-offsetting carry-forward should use it before departure — once gone, it expires.

3. Austria — § 27 EStG, stricter than Germany

Austria has applied a far more comprehensive exit-tax regime since the 2015 tax reform. § 27 (6) (1) (b) EStG covers every form of capital wealth — stocks, ETFs, bonds, fund units, derivatives. There is no 1 % threshold like in Germany: a single Apple share with unrealized gains is enough to trigger exit tax.

The rate: 27.5 % on the fictional gain (KESt special rate, identical to the rate on ongoing capital income in Austria). Tax base: market value minus acquisition cost on the day of departure.

Non-assessment concept for EU/EEA departures. Austria is friendlier than Germany here. For departures within the EU/EEA, the tax is assessed but not collected until actual sale (or further taxable events such as a gift or inheritance to a third-country resident). You actually pay only when you sell — even years later. For departures to a third country (UAE, Switzerland, USA, etc.): immediate assessment and collection of the tax, no installment plan as in Germany.

Value increases abroad. An important advantage of the non-assessment model: if you sell after 5 years abroad at a higher price, only the Austrian unrealized gain at the day of departure is taxed. The additional gain abroad is not Austrian-taxable — provided your new country of residence taxes it correctly. Example: stock bought at 100, worth 200 at departure, sold after 4 years in Cyprus at 350. Austria taxes only the 100 of unrealized gain (200 minus 100), the additional 150 are taxable in Cyprus (or in your new residence).

Switzerland has a special status: thanks to the bilateral agreement with Austria, it counts as EU/EEA-equivalent for exit-tax purposes. That is an important exception many investors miss — a move from Vienna to Zurich triggers assessment but as non-assessment too. It is one of the reasons Switzerland remains the favorite emigration destination for wealthy Austrians.

4. Double-Taxation Treaties — who taxes what

Once you are abroad, two states fight for your taxes: your source state (where the security was issued — USA for Apple, Germany for SAP) and your residence state (e.g. UAE or Cyprus). Double-Taxation Treaties (DTAs) decide who gets how much.

Three main mechanisms you must know:

• Withholding tax on dividends: the issuer state retains a default maximum (USA 30 %, Germany 26.375 %, Switzerland 35 %). The DTA reduces it to a treaty rate (typically 15 %). If your residence state credits the source-state tax, you effectively pay only the higher of the two — not both.
• Capital gains: in most DTAs (OECD model treaty Art. 13 (5)) gains from share sales are taxed ONLY in the residence state. If you live in the UAE and sell Apple shares with a 100,000 euro gain, you pay 0 % — the USA has no taxing right under the treaty.
• Method article: DTAs use either the credit method (residence state taxes worldwide income, credits foreign withholding tax) or the exemption method (residence state does not tax foreign income at all). Germany and Austria mostly use the credit method for stock-related income.

Important: The UAE has no fully ratified DTA with Germany for the majority of use cases (the treaty was signed in 2009 but, due to reciprocity disputes from the UAE side, has not been fully ratified — the status as of 2026 is still “provisionally applicable”). With Austria a complete DTA exists since 2003. With Switzerland both DE and AT have comprehensive DTAs (DE-CH from 1971, multiple revisions; AT-CH from 1974). With Cyprus DTAs from 2011 (DE) and 1990 (AT). With Malta DTA 2001 (DE) and 1978 (AT). With Spain DTA 2011 (DE) and 1966 (AT). With Portugal DTA 1980 (DE) and 1970 (AT) — Portugal hosts the NHR status, which is treaty-compliant by exempting foreign pensions and foreign income.

5. Top 6 destinations — the tax comparison 2026

The “exit-tax risk” column shows what happens when you leave DACH. The “capital gains” and “dividends” columns are the ongoing rates in your new residence country. Green = highly attractive, yellow = medium, no country in this list is red. If you have meaningful trading income, the order is clear: UAE > Switzerland/Cyprus > Malta > Portugal > Spain.

6. Switzerland — private wealth management as a creed

Switzerland has been the favorite emigration target for wealthy Germans and Austrians for decades — and there is a clear reason: private individuals pay no capital-gains tax on share sales in Switzerland. If you sell Apple after 10 years with a 500,000 euro gain, you pay zero Swiss tax on that gain — provided you are classified as a private investor, not as a commercial securities trader. The criteria (the 5-point ESTV test): no leverage, holding period of at least 6 months, transaction volume below 5x equity, secondary nature of trading, no leveraged derivatives.

What Switzerland charges instead: a wealth tax on total net worth, varying widely by canton. Zurich about 0.3 % p.a. on wealth above the 200,000 CHF allowance, Geneva up to 1 %, Schwyz and Zug well below (0.1–0.15 %). On a 1 million CHF portfolio that means 1,000 to 10,000 CHF wealth tax per year depending on the canton — typically far less spread over the year than the German 25 % flat capital-gains tax on realized gains.

On dividends you pay Swiss income tax (federal 0–13.5 % plus canton plus municipality; effectively 20–30 %). For US dividends the IRS withholds 15 % under the DTA (reduced from 30), and the Swiss tax fully credits this — net result similar to home in Germany. But: capital gains are tax-free, and that is the game-changer for buy-and-hold investors.

Residence permit: as an EU citizen (Austrian) you need a B (residence) or C (settlement) permit. Germans fall under the Free Movement Agreement but still need a permit appropriate to their employment status. For wealthy individuals without employment: lump-sum taxation in cantons such as Valais, Ticino, Vaud — minimum tax around 150,000 CHF p.a. on a fictional 7x rent base.

7. UAE / Dubai — the zero-percent solution

The United Arab Emirates is the most radical tax option: zero income tax, zero capital-gains tax, zero dividend tax for private individuals. That has always been the case and was not changed by the Corporate Tax introduced in 2023 (9 % on profits above 375,000 AED), which does not affect private investors.

What you need to become tax-resident in the UAE:

• Residence Visa. Options: Investor Visa (250,000 AED in stocks or real estate), Property Visa (real-estate investment from 750,000 AED), Golden Visa (10 years, from 2 million AED investment), Freelance Permit (about 22,000 AED setup). Plus mandatory health insurance.
• Tax Residency Certificate. After 183 days of residence (or 90 days for UAE citizens and Residents with onshore activity) you receive the TRC — the official document proving residence for DTA purposes.
• Bank account & brokerage. Locally with Emirates NBD, Mashreq, Dubai Islamic. International brokers like Interactive Brokers accept UAE residents. Trade Republic explicitly does not — see section 9.

Catch 1 — the DTA with Germany: the UAE-Germany DTA was signed in 2009 but, due to ongoing reciprocity disputes, has not been finalized in full ratified form by 2026. In practice German tax offices accept the TRC, but withholding-tax reductions on DE shares do not run automatically — you potentially lose the reduction from 26.375 % to 15 %.

Catch 2 — banking: international brokers recognize a UAE address, but Trade Republic and many other DACH brokers force account closure on departure. You must move to an international broker (Interactive Brokers, Saxo Bank) in time.

Catch 3 — social security: in Germany statutory health-insurance membership ends with departure, in the UAE there is no state health system. Private insurance costs 4,000 to 15,000 euros p.a. depending on age. At 35 going to Dubai, that is bearable. At 60, run the numbers carefully.

8. Cyprus — the EU insider tip with Non-Dom status

Cyprus is the smartest EU solution in 2026, especially if the UAE feels too far. The trick is the Non-Domiciled status. As a Non-Dom (for the first 17 years of Cyprus residence) you pay:

• 0 % on dividends worldwide (the regular 17 % Defence Tax does not apply; Non-Doms are exempt).
• 0 % on share capital gains (Cyprus does not tax capital gains on shares at all, neither for Domiciled nor Non-Dom — applies even after the 17 years).
• 0 % on interest (otherwise 30 % Defence Tax — Non-Dom exemption).
• Earned income tax-free up to 19,500 euros, then progressive 20–35 % (top rate from 60,000 euros).

Conditions for Non-Dom: you must not have been Cyprus-domiciled in the last 20 years (almost always satisfied for DACH investors). You also need to become tax resident — either via the “60-day rule” (60 days in Cyprus, no other residence with more than 183 days, a Cyprus business address or employment) or the standard 183-day rule.

In practice: you rent or buy a flat in Limassol or Paphos (a Limassol Marina apartment around 3,000 euros/month, smaller inland flats from 800 euros), and either set up a Cyprus Limited or take a small director role inside it. Setup costs are moderate (lawyer plus accountant about 5,000 euros per year). Climate and quality of life are excellent, EU membership keeps mobility easy. The biggest downside: banking has been slow since the 2013 and 2018 crises, with Bank of Cyprus and Hellenic Bank as the standard options.

9. What happens to your portfolio

Most emigrants underestimate the practical brokerage side. Three scenarios are possible:

Scenario A — Trade Republic, Comdirect, ING and most DACH brokers: on an address change abroad (outside EU/EEA) the account is almost always frozen or terminated. For moves within the EU/EEA most brokers accept the new residence with adjusted withholding-tax handling. Trade Republic is explicitly “EU only” — moving to the UAE triggers forced closure with a 90-day transfer window. Anyone who forgets this and just moves risks a forced liquidation of all positions with full German capital-gains tax.

Scenario B — international brokers (Interactive Brokers, Saxo, DEGIRO Light): they typically accept residence changes without much friction and adjust the W-8BEN form to your new country. UAE: 30 % US withholding tax (no DTA reduction protection); Switzerland: 15 %; Cyprus: 15 %. An important point — the 15-percentage-point withholding difference can make a major net-yield difference for US dividend strategies.

Scenario C — Swiss brokers (Swissquote, Saxo CH): normally accept Swiss residents and other EU residents depending on the country. Advantage: no complications with the German or Austrian tax office after departure, a clean break.

Practical tip: Open an Interactive Brokers account before you change residence. It is the international gold standard, accepts more than 200 countries as residence, has low fees and a complete asset universe. Transfer your DACH positions in-kind (no taxable sale, full cost-basis preservation) before deregistering. Duration: 4 to 8 weeks. Only after that report the residence change to your local town hall.

11. FAQ — the most common questions

Bottom Line

Exit tax is the only tax you pay without earning a single cent. Germany applies it via § 6 AStG only to “substantial holdings” of 1 % or more, Austria via § 27 EStG to all capital wealth — both with different deferral and return rules. The 2022 ATAD reform abolished Germany’s old EU privilege of permanent deferral and replaced it with uniform 7-year installments.

For destination choice there is no universal answer. If you want maximum tax-freedom, go to the UAE — but pay the price in 30 % US withholding without DTA protection, private health-insurance costs and banking friction. If you want EU proximity and buy-and-hold without sales tax, choose Switzerland or Cyprus. If you seek lifestyle and accept 28 % capital tax, Portugal or Spain make sense.

The most important rule on exit is sequence: first transfer all DACH brokerage accounts to Interactive Brokers or another international broker, use up loss-offsetting buckets, hire a tax advisor — and only at the very end deregister at the town hall. Reverse the order and you risk forced liquidations with full German capital-gains tax. Plan at least 12 months ahead, get specialist advice, and treat the tax part with the same care as finding an apartment in the new country. The right preparation can mean six-figure savings — the wrong preparation costs exactly that.
