If you are a German entrepreneur or founder with a significant stake in a GmbH, AG, or similar corporation, the 2026 reform of the German exit tax Dubai calculation has quietly reshaped your relocation math. Section 6 of the Außensteuergesetz (AStG) has always been a friction point for Germans moving abroad permanently. From January 2026 it is sharper, stricter, and considerably more expensive to defer. This guide explains what changed, who is caught, and how to plan an orderly move from Germany to Dubai without triggering a surprise tax bill the size of your company valuation.
This is not tax advice. It is a structured briefing for founders who want to walk into a conversation with a Steuerberater already understanding the rules.
What the German Exit Tax Actually Is
In plain language: if you are a German tax resident and you own at least 1 % of a corporation (at any point in the last five years), and you give up your unlimited German tax liability by moving abroad, German tax authorities pretend you sold your shares on the day you leave. They tax the imaginary capital gain as if you had cashed out.
You did not actually sell anything. You still own every share. But the state treats the move itself as a taxable realisation event.
The §6 AStG Trigger Threshold
Shareholding threshold: ≥ 1 % in a domestic or foreign corporation, held at any point within the last five years
Residency trigger: giving up unbeschränkte Steuerpflicht (unlimited tax liability) in Germany
Tax base: the difference between the fair market value of the shares on exit day and the original acquisition cost
Tax rate applied: the Teileinkünfteverfahren, 60 % of the gain is taxable, taxed at your personal progressive rate (up to 45 %) plus Solidaritätszuschlag and, if applicable, Kirchensteuer
A founder who built a GmbH worth 10 million euros from zero faces a notional gain of 10 million, of which 6 million enters the tax base, giving an effective tax liability somewhere north of 2.5 million euros. On a move. Before any liquidity event.
What Changed From January 2026
The 2026 reform did not invent the German exit tax Dubai problem, but it made the escape routes narrower. Here is what shifted.
Installment Payment Window Tightened
Previously, founders moving to a non-EU or non-EEA country (Dubai qualifies) could apply for a seven-year installment plan for the tax liability, secured against collateral. The 2026 reform shortens this to a five-year schedule and front-loads the payments, so more of the tax is due early in the window.
Interest on Deferred Payments Increased
The interest rate charged on deferred exit tax installments is now pegged to a higher benchmark, reflecting current Bundesbank reference rates. For a 2.5 million euro liability deferred over five years, the carrying cost alone can reach several hundred thousand euros.
The Seven-Year Return Safe Harbour: Narrowed
The old rules offered relief if the taxpayer returned to Germany within seven years, reversing the exit tax. The 2026 reform narrows the definition of a qualifying return: the taxpayer must now demonstrate that the original departure was always intended as temporary, backed by written evidence (employment contracts, family arrangements, return bookings). Vague intentions no longer suffice.
Expanded Trigger Events
The reform expanded the list of events that count as "giving up" German tax residency beyond the classic move abroad. Contributing shares to a foreign entity, certain reorganisations involving non-EU holding structures, and extended stays abroad that break the 183-day threshold can all now trigger the tax, even without a formal deregistration.
Higher Documentation Burden
Collateral requirements for installment plans have tightened. Acceptable collateral is now narrower (no family guarantees, limited acceptance of foreign-held assets), and filings must be more detailed. Incomplete filings can cause the installment plan to collapse, accelerating the full tax bill into a single due date.
Exit Without Exiting: The 2025 BFH Rulings on Passive Exit Taxation
Until late 2025 most German entrepreneurs assumed exit tax was something you only triggered by actively giving up German tax residency. The Bundesfinanzhof (Germany's highest tax court) corrected that assumption with two rulings dated 19 November 2025, published 26 March 2026 (case numbers I R 41/22 and I R 6/23). The court held that a mere change in law can trigger exit taxation even when the taxpayer has not moved.
This is what tax practitioners now call passive Wegzugsbesteuerung. The trigger is not your relocation. It is the loss of Germany's right to tax your shareholding under a tax treaty, which can happen because the treaty was renegotiated, because you held shares in a company that itself moved, or because a corporate restructure put your stake under a different jurisdiction.
For a German-domiciled entrepreneur with a Dubai operation already in motion, three specific scenarios now carry passive exit taxation risk:
1. You hold a stake greater than 1% in a German GmbH that converts to a Maltese, Cypriot, or other low-tax EU vehicle while you stay German-resident. The legal restructure, not your residency, can trigger §6 AStG.
2. You participate in a foreign holding that re-domiciles. If your equity sits in a vehicle that itself moves out of Germany's tax reach, you can be deemed to have exited without ever leaving the country.
3. A renegotiated double-tax treaty between Germany and your asset's domicile changes Germany's source rights. The BFH ruling makes clear: this counts as a triggering event in itself.
What this changes in practice: the planning checklist in the section above is no longer enough. Even if you have no relocation plans, a year-end audit of your shareholding structure is now part of cautious tax hygiene for any DACH-resident with cross-border equity. Specifically: ask your Steuerberater whether any of your holdings sits in a structure that has relocated, restructured, or come under a renegotiated treaty since 2024. The BFH rulings have a long shadow because §6 AStG already treats the original passive trigger as deemed disposal at fair market value. Tax owed is real, even if no money changes hands.
The honest reading: for entrepreneurs already moving to Dubai through the active exit-tax route, this changes nothing in your plan. For those staying in Germany while owning anything that crosses borders, this changes the assumption that I am not moving was a safe answer. It no longer is.
Why Dubai Specifically Is More Expensive Now
Dubai has long been one of the most attractive destinations for DACH founders because of its 0 % personal income tax, 9 % corporate tax ceiling, and residency pathways tied to business setup or property investment. But the UAE is not in the EU or EEA. That single geographic fact turns the German exit tax Dubai calculation into something quite different from moving to, say, Portugal or Austria.
EU/EEA destinations: historically benefited from indefinite interest-free deferral until an actual sale, because of EU freedom-of-establishment law
Non-EU destinations like Dubai: immediate tax liability, subject only to the narrowed installment plan, with interest charged
The 2026 reform does not eliminate this distinction, but it pushes non-EU movers closer to the "pay now" end of the spectrum. Founders planning a Dubai move are squarely in the tightened regime.
How the Tax Is Calculated: A Worked Example
Assume a founder holds 100 % of a GmbH. Acquisition cost: 25.000 euros (original share capital). Fair market value on exit day: 5.000.000 euros.
Line | Amount |
Fair market value | 5,000,000 EUR |
Acquisition cost | 25,000 EUR |
Notional capital gain | 4,975,000 EUR |
Taxable portion (60 % Teileinkünfte) | 2,985,000 EUR |
Effective tax (approx. 45 % + Soli) | approx. 1,350,000 EUR |
That 1.35 million is notionally due on the day you deregister in Germany. Under the 2026 installment plan it is payable over five years with interest. The bill is real; the cash is not, because no shares have been sold.
This is the central planning problem: the tax arrives before the liquidity.
Planning Steps Before You Move
1. Valuation Before Relocation
Get a defensible, documented company valuation from a qualified auditor before you deregister. The Finanzamt will challenge weak valuations and apply its own, usually higher, figure. A conservative but well-argued valuation report is the single most important document in any §6 AStG filing. For businesses with irregular earnings, consider the IDW S1 valuation standard or a DCF with clearly stated assumptions.
2. Restructure Before the Trigger, Not After
Options that must be executed before residency changes include:
Gifting minority stakes to family members already tax-resident in Dubai or another suitable jurisdiction, reducing your personal shareholding under planning rules
Converting corporate holdings into a partnership (KG or GmbH & Co. KG) where §6 AStG does not apply in the same way to the partnership interest itself (though other rules still do)
Selling to an employee participation plan or external investor before the move, triggering real capital gains (also taxable, but at least matched by actual cash)
Each option has its own pitfalls under German anti-abuse rules (§42 AO). None of them are casual paperwork exercises.
3. Time the Move Around Business Events
If your GmbH is about to receive a large commission, sign a major contract, or raise capital, these events will push valuation up. Moving after such an event means a higher tax base. Moving just before a valuation-lifting event, without signals you were timing it, can be defensible.
4. Set Up the Dubai Structure Before, Not During
A Dubai holding company, a mainland UAE LLC, or a free zone entity takes weeks to establish. If you deregister in Germany without receiving entities in place, you create a window where your German shares are dangling and your receiving structure is not ready. Our guide on [setting up a company in Dubai: costs and steps 2026](https://www.startdxb.ae/articles) walks through the timeline.
5. Plan the Installment Plan Collateral
Under the tightened 2026 rules, acceptable collateral is usually:
German-located real estate with unencumbered equity
Shares in the departing company itself (still owned by the taxpayer)
Bank guarantees from a German or EU credit institution
If you do not have qualifying collateral, the installment plan is denied and the full tax is due on a single date. Plan the collateral side of the paperwork before the move, not after.
6. Coordinate With Your Dubai Residency
A UAE Golden Visa, investor visa, or mainland business licence does not itself change the German exit tax calculation, but it can reinforce the case that the move is genuine and permanent. This matters for anti-abuse challenges from the Finanzamt, who may argue a short-term move was never real.

Common Mistakes That Trigger Bigger Bills
Deregistering in Germany before the Dubai entity or residency is confirmed, creating a tax residency gap
Assuming the old seven-year rule still applies in its earlier, looser form
Using family assets as collateral, which the 2026 reform generally no longer accepts
Relying on a home-built valuation instead of a certified report
Forgetting that partnership conversions have their own exit-tax cousins under §16 EStG

The Interaction With Dubai's Tax System
Dubai does not levy personal income tax on capital gains, which is why the move is attractive in the first place. Corporate tax in the UAE applies at 9 % on profits above AED 375.000, with free zone companies potentially qualifying for 0 % on specific qualifying income. But none of this helps with the German exit tax itself. That liability is settled with the German Finanzamt, in euros, on the schedule Germany sets. Dubai simply provides the zero-tax environment the shares will live in from that point forward.

When the Math Still Works
Even with the 2026 reform, a Dubai move can be net positive for founders whose companies will generate significant future income that would otherwise be taxed at German rates. A one-time exit tax of 1 to 2 million euros looks different against 20 years of income that would have faced combined German personal and corporate tax approaching 45 to 48 %. The calculation hinges on:
Expected earnings of the corporation after relocation
Expected dividend or sale path
How long the founder intends to stay in Dubai
Whether the company can plausibly be wound down and relaunched rather than transferred
For most founders in the 5 to 50 million euro valuation range, the break-even point on moving versus staying sits somewhere between three and seven years of post-move earnings. Below that, the reform has moved the goalpost significantly. Above it, the Dubai move still pencils out.
FAQ
Does the 2026 reform apply retroactively to moves already completed?
No. Moves completed and assessed before 1 January 2026 continue under the previous rules. If you moved in 2023 and your installment plan is already running, it follows the old seven-year schedule. However, fresh trigger events after 2026 (such as a second move, a shareholding increase, or a qualifying reorganisation) fall under the new rules.
Can I avoid the German exit tax Dubai liability by keeping a German address?
Not safely. The Finanzamt looks at substance: where you physically live most of the year, where your family is, where your centre of life is. A fake German address while actually living in Dubai risks both losing the tax planning benefit and triggering tax evasion charges. This is not a workaround worth attempting.
What happens if I move back to Germany within five years?
Under the 2026 rules, if you return to Germany before the installment plan is complete and before any actual sale of the shares, you can apply for the exit tax to be reversed. The qualifying conditions are stricter than before: you must show the original departure was planned as temporary, with supporting documentation, and the return must be genuine. Paying the installments in the meantime is mandatory.
Does the German exit tax apply to real estate or just shares?
Primarily shares. Real estate you own directly is not caught by §6 AStG in the same way, though it comes with its own set of German tax rules on rental income and on sale. A holding of shares in a German real estate company, however, can be caught if it meets the 1 % threshold.
If my GmbH has been unprofitable, is there still a tax?
Potentially yes, because the tax base is fair market value, not profit. An unprofitable but asset-heavy GmbH (property, cash reserves, IP) can still carry a high valuation. The best counter is documented low fair market value through a proper auditor report, not optimistic accounting.
What to Do Next
The German exit tax Dubai calculation is solvable, but not with a weekend of research.
