You deregister in Germany. You land in Dubai. You assume Germany is done with you. Often it is not.
The reason is the German extended limited tax liability, known in German as the erweiterte beschränkte Steuerpflicht. It sits in Section 2 of the Foreign Tax Act (the Aussensteuergesetz, or AStG). It keeps German nationals inside the German tax net for up to ten more years after they leave.
Not on worldwide income. But on far more than an ordinary non-resident would ever pay.
This is not a fringe rule. It is live law, and the German finance ministry restated its official reading of the whole Act in a document running past 200 pages, the 2023 principles for applying the Foreign Tax Act. Yet it appears on almost no page that sells "tax free in Dubai".
This article does three things. It says what the rule is. It says whether it catches you. It says what it costs. It is not a guide to dodging it. If it applies to you, you need a German tax adviser, not a workaround.
What Section 2 AStG actually does
Normally the logic is simple. Give up your German home, and unlimited tax liability ends. After that only limited tax liability applies, under Section 49 of the Income Tax Act (the Einkommensteuergesetz, or EStG). That covers a short, defined list: German rental income, German permanent establishments, some capital income.
Section 2 AStG inverts the list. It catches everything that is not foreign income within the meaning of Section 34d EStG. That is a negative definition, and it is much wider than Section 49.
One example makes the gap visible. Interest paid by a German borrower is not foreign income, because Section 34d requires a debtor based abroad. For an ordinary non-resident, that interest is untaxed in Germany. For someone under Section 2 AStG, it is taxable.
There is a further twist most readers miss. Section 2 paragraph 1 sentence 2 AStG assumes a German place-of-management permanent establishment for income not earned through a foreign permanent establishment or a foreign permanent representative. In plain terms: build no real substance in Dubai, and Germany can still allocate the income to itself.
Does the German extended limited tax liability catch you? Three gates
Three conditions must be met at the same time. Miss one, and Section 2 AStG does not apply.
Gate 1: five of the last ten years as a German taxpayer
You must have been subject to unlimited German income tax as a German national for at least five years in total during the ten years before your unlimited liability ended. The five years do not have to be consecutive.
Two consequences follow. Someone who never held German citizenship is outside the rule, even after twenty years living in Munich. And giving up the passport after leaving changes nothing, because the test looks backwards.
Gate 2: you live in a low-tax jurisdiction
The second condition is residence in a territory with low taxation, or residence in no country at all. The UAE clears the first version easily. The arithmetic is in the next section.
Gate 3: substantial economic interests in Germany
This is the gate that decides most real cases. Section 2 paragraph 3 AStG gives three alternatives, and any one of them is enough:
| # | Test | Threshold |
|---|---|---|
| 1 | You are the owner or a co-entrepreneur of a German business. As a limited partner: more than 25 percent of the profit share. Or you hold a shareholding within the meaning of Section 17 EStG in a German corporation. | from a 1 percent GmbH stake |
| 2 | Income that is not foreign income under Section 34d EStG. | more than 30 percent of all your income or above EUR 62,000 |
| 3 | Assets whose returns would not be foreign income. | more than 30 percent of total assets or above EUR 154,000 |
The 1 percent line in test 1 is the one people underestimate. A small stake left over from an old start-up is enough. So is a rented flat in Hamburg worth more than EUR 154,000, this time through test 3.
Germany, Section 2 Foreign Tax Act
Three gates, and all three must be open at once
Extended limited tax liability is not triggered by moving to Dubai on its own. It needs every one of these conditions to be true in the same year. One closed gate and the rule does not apply.
You were German, and taxed as one
Subject to unlimited German income tax as a German national. The years do not have to run back to back.
Your new home is a low-tax territory
Measured on a fixed benchmark: an unmarried person with taxable income of EUR 77,000. The UAE levies no personal income tax at all.
You kept substantial economic interests in Germany
Three alternative tests, and any single one is enough. This is where most real cases are decided.
All three open: Germany taxes you for up to ten more years
The net covers everything that is not foreign income under Section 34d of the Income Tax Act, at the rate set by your worldwide income, until the end of the tenth year after departure.
One final filter. The rule only applies in a year where the income it catches exceeds EUR 16,500. That is a cliff, not an allowance: one euro over and the whole amount is inside.

Is Dubai a low-tax jurisdiction? The actual maths
Section 2 paragraph 2 number 1 AStG sets an abstract comparison. You take an unmarried person with taxable income of EUR 77,000 and compare the tax burden.
Germany's 2026 basic tariff sits in Section 32a EStG. In the fourth tariff band it reads: 0.42 times income, minus EUR 11,135.63. That gives:
- German income tax on EUR 77,000: about EUR 21,204, roughly 27.5 percent.
- A territory counts as low-tax if its burden is more than one third lower. So the line sits at about EUR 14,136.
- UAE income tax on that person: zero. The government states plainly that the country does not levy income tax on individuals.
The test is not narrowly failed. It is failed by the whole amount. There is a counter-exception: you escape the label if you prove that the taxes actually paid on your income reach at least two thirds of the German figure. For a private individual in the UAE that is close to impossible.
What about the UAE's 9 percent corporate tax? It is a business tax, not a personal income tax tariff. The abstract comparison in Section 2 paragraph 2 number 1 looks at income tax on a natural person, so the corporate rate does not answer it. Whether it can ever feed the two-thirds escape clause is a question for an adviser, not for a website.
That zero-percent reality is exactly where marketing and law part company. We break down what Germans really pay in tax in Dubai elsewhere. The low local burden is genuine. It is also the trigger for Section 2 AStG.
Which income Germany reaches
The boundary follows Section 34d EStG. Anything that is not foreign income under that list falls into the net.
| Income | Inside the Section 2 net? | Why |
|---|---|---|
| Rent from a flat in Berlin | Yes | German immovable property. |
| Interest from a German bank or a German borrower | Yes | Section 34d no. 6 requires a foreign debtor. |
| Gain on selling a German GmbH stake | Yes | Seat and management are in Germany. |
| Fees earned with no real UAE establishment | Often yes | The deemed German management establishment applies. |
| Salary for work physically performed in Dubai | No | Section 34d no. 5: the work is done abroad. |
| Profit of a genuine operating establishment in Dubai | No | Section 34d no. 2. |
| Rent from an apartment in Dubai Marina | No | Section 34d no. 7. |
The bottom half of that table is the good news. Live in Dubai, work in Dubai, and run a real company there with an office, staff and decisions made locally, and you earn foreign income. That stays outside. What gets caught is mostly what you left behind in Germany.
Rate, ceiling and the small-amounts line
Three technical points decide the final number.
The rate. Under Section 2 paragraph 5 AStG, the rate applied is the one that results from all of the person's income. That is a progression effect. Your Dubai income lifts the rate on the German income, even though it is not taxed itself. Capital income under the flat-rate regime of Section 32d paragraph 1 EStG is left out when the rate is worked out.
The ceiling. Section 2 paragraph 6 AStG caps the whole thing. If you show that the extra tax produces a higher German bill than you would have faced with unlimited liability and a home in Germany, the excess is not collected. Section 2 is meant to neutralise the move, not to punish it.
The small-amounts line. Section 2 paragraph 1 sentence 3 AStG only applies in assessment periods where the income caught exceeds EUR 16,500. That is a cliff, not an allowance. At EUR 16,501 the full amount is inside, not just the one euro above.
Why the tax treaty does not rescue you
When someone moves to a treaty country, the treaty often softens what domestic law demands. For the UAE that cushion is gone.
The agreement of 1 July 2010 was not renewed. It ran out on 31 December 2021. In the finance ministry's official register showing the status of German tax treaties at 1 January 2026, the United Arab Emirates entry is marked as applying only "bis 31.12.2021", meaning up to that date. No successor income tax treaty appears in the same document's list of live negotiations.
Since 2022 only domestic law on each side applies. We cover the practical fallout in our guide to the Germany-UAE double taxation agreement. For Section 2 AStG the consequence is short: no treaty rule limits it.
Non-residents should also note how Germany itself defines residence and the reach of limited liability. PwC's summary of German tax residence is a useful English-language starting point before you speak to an adviser.
The ten years run differently from what most people assume
The period does not end ten years after your moving day. It ends ten years after the end of the year in which unlimited liability ceased.
Take an example. You leave on 15 March 2026, and unlimited liability ends that day. The year closes on 31 December 2026. Ten years later is 31 December 2036. So the tail covers the rest of 2026 plus the ten calendar years 2027 to 2036. That is a little over ten and a half years.
One important nuance: not every one of those years automatically produces a German tax bill. The conditions are tested separately for each assessment period. Sell the German GmbH stake in year four and close the German accounts, and you may fall under every threshold in year five. The rule then does not bite for that year, even though the clock keeps running.
Worked example
The clock does not start on your moving day
Three German windows open at once when a German national leaves for Dubai, and they close on different dates. This example uses a departure on 15 March 2026.
Each year is judged on its own facts
The bars show the maximum reach, not an automatic bill. Every assessment period is tested separately. Fall below all three "substantial economic interests" thresholds in a given year, or below the EUR 16,500 line, and the rule does not bite that year. The clock still keeps running.

The inheritance tax twin: Section 4 AStG
Income tax is only half of it. Two inheritance tax rules run alongside.
First, under Section 2 paragraph 1 number 1 letter b of the Inheritance Tax Act, German nationals still count as domestic taxpayers for five years after leaving. During that window the entire worldwide estate is exposed to German inheritance and gift tax.
Second, Section 4 AStG takes over after that. As long as Section 2 paragraph 1 sentence 1 AStG applies, inheritance tax reaches every part of the estate whose returns would not be foreign income. It is the same wide negative definition, applied to assets instead of income. Section 4 paragraph 2 offers one way out: prove a foreign inheritance tax of at least 30 percent of the German amount. The UAE levies no inheritance tax, so that door is shut.
The result: five years of unlimited inheritance tax exposure, then the extended version until the end of year ten.
What this means in practice
Four points belong on the table before the move, not after it.
- Leaving has two separate tax events. Section 6 AStG taxes unrealised gains in corporate shareholdings at the moment of departure. That is the German exit tax on shareholdings, a one-off. Section 2 AStG is the running tail that follows. One case can trigger both.
- You still file. If Section 2 applies and you are above the small-amounts line, a German tax return is still due. The competent office follows from Section 19 of the Fiscal Code.
- Documentation decides close cases. A tax residency certificate, evidence of real substance in the UAE, and a statement of your German assets at the start of the year. If you sit just under test 3, you have to be able to show it.
- Get German advice, not only Emirati advice. A company formation agent in Dubai knows UAE law. Section 2 AStG is German law and belongs with a German tax adviser. For the wider picture of moving to Dubai from Germany, start with our main guide.
The honest summary is this. Dubai does lower the ongoing tax on what happens in Dubai. For what stays behind in Germany, the German claim survives for a decade. Know that in advance and you plan cleanly. Learn it in year four and you have back taxes and interest to deal with.
