German Tax — More Complex Than Most Nationalities
German expats in Dubai face a more complex tax transition than most nationalities. Germany has aggressive anti-avoidance legislation (§6 AStG exit tax, §2 AStG extended limited liability) and one of the world's most thorough international information-exchange networks. Done correctly, German Dubai residents can achieve a very clean 0% UAE tax position. Done incorrectly, the Finanzamt can maintain significant tax claims for years after departure.
This guide covers the key German tax issues specific to Dubai residents: the §6 AStG Wegzugbesteuerung (exit tax), the Germany-UAE DBA (double tax agreement), ongoing German-source income obligations, the UAE Tax Residency Certificate (TRC) process, inheritance tax tail, and how to structure a clean break.
Critical: four German tax risks for Dubai expats
(1) Wegzugbesteuerung (§6 AStG): If you held >1% of any company shares in the last 5 years, exit tax may be due — potentially six figures. No EU installment plan for UAE. (2) Erweiterte beschränkte Steuerpflicht (§2 AStG): 10-year extended German tax liability for German citizens moving to low-tax countries (UAE qualifies). (3) Erbschaftsteuer 5-year tail: German inheritance tax applies for 5 years post-emigration on worldwide assets. (4) Residential ties: Any personally-used German property can re-establish German tax residency, negating the UAE benefit entirely. All four require specialist advice.
Wegzugbesteuerung (§6 AStG) — Exit Tax Deep Dive
The Wegzugbesteuerung (exit tax) under §6 AStG is the most significant tax risk for German entrepreneurs and business owners relocating to Dubai. It applies if:
- You held more than 1% of a corporation (GmbH, AG, SE, etc.) at any point in the last 5 years before departure
- You were a German tax resident for at least 7 of the last 12 years
- You emigrate to a non-EU/EEA country or otherwise lose German unlimited tax liability
The tax is calculated as if you sold your shares at market value on the day of departure. The market value minus acquisition cost equals a deemed capital gain, taxed at approximately 25.38% (25% Abgeltungsteuer + 1.375% Soli).
Post-2022 reform: stricter for non-EU emigration
The 2022 ATAD2 reform tightened §6 AStG significantly. For emigration to non-EU/EEA destinations (UAE): the full Wegzugsteuer is due without installments. The Finanzamt may require collateral (Sicherheitsleistung) — such as a bank guarantee, asset pledge, or escrow — before allowing departure in practice. Early planning (12–18 months) is essential to explore restructuring options before the exit.
§6 AStG payment options comparison
Emigration DestinationEU / EEA countries (France, Netherlands, Austria, etc.)
Payment Terms7-year interest-free installments available (if permanent EU/EEA residency obtained)
Collateral Required?Generally not required for EU/EEA if deemed low risk
Post-2022 Reform StatusImproved — ATAD2 compliance; EU freedoms maintained
Planning OptionsMaximize installment election; plan re-entry to Germany carefully to avoid early crystallisation
Emigration DestinationNon-EU/EEA — including UAE (Dubai)
Payment TermsFull lump sum due immediately (or on first installment due date)
Collateral Required?Finanzamt may require security/collateral for deferral — e.g. bank guarantee or pledge of assets
Post-2022 Reform StatusTightened by 2022 ATAD2 reform — lump-sum requirement confirmed for non-EU; collateral rules stricter
Planning OptionsPlan shareholding restructure pre-departure; consider EU intermediate step; value shares accurately pre-exit
Emigration DestinationReturn to Germany within 7 years (§6(3) AStG)
Payment TermsTax may be reversed / waived if you return and re-establish German tax residency within 7 years
Collateral Required?TBC based on Finanzamt assessment
Post-2022 Reform Status7-year return window maintained post-2022
Planning OptionsSome expats plan a 7-year Dubai stay specifically to avoid permanent crystallisation; then return
Emigration DestinationDeemed re-emigration after German return
Payment TermsIf you return to Germany and then re-emigrate, §6 AStG can re-trigger on accumulated new gains
Collateral Required?Same rules as original emigration apply
Post-2022 Reform StatusAnti-avoidance rules prevent simple cycling between Germany and non-EU
Planning OptionsMulti-step emigration via EU country is complex but can optimise; specialist advice essential
German vs UAE Tax Treatment by Income Type
Once you have established UAE tax residency and broken German unlimited tax liability, German taxation is limited to German-source income under the DBA. The following table shows how each income type is treated.
Income TypeUAE employment income (Dubai salary)
German Tax Treatment (while Dubai resident)0% (DBA: income taxable only where work performed if UAE tax resident)
UAE / Dubai Tax Treatment0% — no UAE income tax

Income TypeGerman employment income (work days in Germany)
German Tax Treatment (while Dubai resident)Taxable in Germany — proportionate to days worked in Germany
UAE / Dubai Tax Treatment0% UAE tax
DBA Treaty Allocates ToGermany (source country)
Key NotesEven a few German work days can create German taxable income; track carefully

UAE / Dubai Tax Treatment0% UAE inheritance/gift tax
DBA Treaty Allocates ToNo DBA inheritance article; domestic law applies
Key Notes5-year tail on German inheritance tax post-emigration is critical planning point
The Germany-UAE DBA (Doppelbesteuerungsabkommen)
The Germany-UAE DBA entered into force on 1 January 2010. It follows the OECD Model Convention and prevents double taxation by allocating taxing rights between the two countries. Key provisions:
DBA Articles — Germany retains right to tax
- Art. 6: Rental income from German real property → Germany
- Art. 13(1): Gains on German real property → Germany
- Art. 18: German state pension (DRV) → Germany
- Art. 15: German employment days (work physically in Germany) → Germany
DBA Articles — UAE residence country gets priority
- Art. 7: Business profits of UAE-based enterprise → UAE
- Art. 11: Interest income → residence country (UAE)
- Art. 13(4): Share capital gains (non-property) → UAE (residence)
- Art. 15: UAE employment income → UAE (0% tax)
DBA tie-breaker: 'centre of life interests'
If both Germany and UAE could claim tax residency, DBA Article 4 applies a sequential tie-breaker: (1) Permanent home location, (2) Centre of vital interests (where your personal and economic ties are strongest), (3) Habitual abode, (4) Nationality. Most German Dubai expats win the tie-breaker at step (2) or (3) by: surrendering their German permanent home, bringing family to Dubai, and demonstrating genuine UAE economic activity. A UAE TRC does not automatically win the tie-breaker — the Finanzamt can still challenge your position if German ties remain strong.
8-Step Process: Establishing UAE Tax Residency
- 1
Break German tax residency formally
Register your departure (Abmeldung) at your German municipality's Einwohnermeldeamt. Notify the Finanzamt of your new UAE address. Critically: surrender any German property you were personally using (or commercially rent it out with no personal use clause). Without this step, you may maintain German tax residency (Wohnsitz or gewöhnlicher Aufenthalt) even while physically living in Dubai.Time: On or before departure - 2
Establish physical presence in UAE (183+ days in year 1)
UAE tax residency for TRC purposes requires 183 days of physical presence in the UAE within a 12-month period. Keep detailed travel records from day one — passport stamps, boarding passes, UAE access logs. German tax-residency break also requires genuinely spending the majority of your time outside Germany. Ensure you do not spend 183+ days in Germany in any calendar year and have no German Wohnsitz.Time: Year 1 - 3
Open UAE bank account and establish UAE economic footprint
Open a UAE bank account at Emirates NBD, FAB, or ADCB. Start a UAE lease agreement (Ejari registered). Register your UAE employer's payroll to your UAE bank. These steps demonstrate genuine UAE economic activity — important if the Finanzamt ever challenges your UAE residency under the DBA 'centre of life interests' test.Time: Weeks 1–4 in Dubai - 4
Obtain UAE Tax Residency Certificate (TRC)
Apply to the UAE Federal Tax Authority (FTA) for a Tax Residency Certificate (TRC) after completing 183 days of UAE presence. Required documents: Emirates ID, UAE residency visa, passport, bank statements, UAE lease contract, employer letter (or trade licence for business owners). FTA processes in 4–8 weeks. Cost: AED 1,000–2,000. This certificate is your primary treaty document for invoking the Germany-UAE DBA against the Finanzamt.Cost: AED 1,000–2,000 FTA fee; AED 3,000–8,000 adviser fees for full applicationTime: After 183 UAE days (typically months 7–9) - 5
Submit UAE TRC to German Finanzamt
Present your UAE TRC to the Finanzamt along with a formal declaration of UAE tax residency. The DBA 'tie-breaker' provisions (permanent home, centre of vital interests, habitual abode, nationality) are applied in sequence if both Germany and UAE claim residency. A UAE TRC strengthens your position significantly. The Finanzamt may still apply erweiterte beschränkte Steuerpflicht (10-year tail) for German-source income — the TRC doesn't eliminate this but confirms UAE residency for DBA purposes.Time: After obtaining UAE TRC - 6
Address Wegzugbesteuerung (§6 AStG) if applicable
If you held >1% of a corporation in the last 5 years, your German Steuerberater should have already assessed the §6 AStG liability before your departure. If not done pre-departure, engage a specialist immediately. Post-departure options are very limited. The Finanzamt will assess the exit tax on your last German tax return for the year of departure. Explore: was the departure year correctly identified? Were shares correctly valued? Were any exemptions or deferral options available?Cost: Steuerberater fees EUR 2,000–15,000+; tax liability potentially six figuresTime: Year of departure and year after - 7
File last comprehensive German tax return (year of departure)
Your German Einkommensteuererklärung for the year of departure covers: all worldwide income up to date of departure + German-source income from date of departure to year end + Wegzugbesteuerung deemed disposal (if applicable). This return is filed with the Finanzamt of your last German tax district. All subsequent years (while in UAE): only German-source income (rental, German dividends, German pension, German work days) needs to be filed.Time: By 31 July following departure year (or 31 October with adviser extension) - 8
Establish ongoing German return filing for German-source income
If you have ongoing German-source income (rental property, dividends, German work days, German pension when drawing), you must file annual German Einkommensteuererklärungen as a beschränkt Steuerpflichtiger. This is not optional — the Finanzamt will assess penalties for late or non-filing. File via ELSTER online or engage your German Steuerberater. The §2 AStG extended limited liability may also require reporting of certain deemed German-source income during the 10-year window.Cost: Steuerberater: EUR 800–6,000/yr depending on complexityTime: Annually thereafter
German Rental Property: Ongoing Obligations
German rental income is the most common ongoing German tax obligation for Dubai residents. The income is unambiguously German-source under DBA Article 6 — Germany has the exclusive right to tax it. There is no UAE tax on German rental income.
Allowable Deductions (German rental)
- Mortgage interest (Schuldzinsen)
- Building depreciation: 2% p.a. (pre-2023); 3% p.a. (from 2023)
- Maintenance and repairs (Instandhaltungskosten)
- Property management fees (Hausverwaltung)
- Grundsteuer (property tax)
- Building insurance (Gebäudeversicherung)
- Steuerberater fees for property-related returns
Key Rules for Non-Resident Landlords
- File annual Einkommensteuererklärung with SA105-equivalent
- German personal allowance (EUR 11,604 in 2026) partially accessible for DBA-country non-residents
- No capital gains tax on property sale after 10 years of ownership (Spekulationssteuer exemption)
- No personal use allowed — must be on full commercial letting terms to avoid Wohnsitz issues
- Property mortgage with German bank: notify lender of non-resident status; rates generally maintained
German Pension Tax in Dubai
German state pension (DRV Rente) is taxable in Germany for all recipients — regardless of where they live. The taxable portion has been increasing progressively and reaches 100% for those retiring from 2040 onwards. Current (2026) taxable portion for new retirees: approximately 83%.
DRV pension taxable in Germany — always
Even as a UAE resident receiving 0% UAE tax treatment, your German DRV state pension is taxable in Germany. You must file annual German tax returns for the years you receive DRV pension. The German personal allowance (Grundfreibetrag EUR 11,604 in 2026) means modest pensions may have minimal German tax — but you must file to establish this. Private pension income (Rürup) and occupational pension income may be treated differently under the DBA — get specific advice for your pension types.
German Inheritance Tax (Erbschaftsteuer) — 5-Year Tail
Germany's inheritance and gift tax (Erbschaftsteuer/Schenkungsteuer) applies if either the deceased or the beneficiary was German tax resident within the 5 years before the inheritance event. This creates a 5-year tail exposure for newly-departed German expats.
5-year German inheritance tail
If you emigrate to Dubai and receive an inheritance within 5 years, German Erbschaftsteuer may apply to: (1) German-situs assets (German property, German accounts), AND (2) Worldwide assets if either you or the deceased were German tax resident within 5 years. After 5 years post-emigration, German Erbschaftsteuer applies only to German-situs assets for non-residents. For substantial inheritances expected within 5 years of departure, specialist German Steuerberater + Notar advice before emigration is critical. Standard Class I allowances still apply (EUR 400,000 for spouse; EUR 400,000 per child).

Full Break vs Keeping German Rental Property
Full Break (sell German property)
- Clean German tax position — only file for genuine German-source income
- No personal ties that could re-establish German tax residency
- Simplifies future planning — no German property management at distance
- Capital from German property sale can be deployed in UAE (0% CGT environment)
- Reduces future German inheritance tax exposure (5-year tail only, then non-German assets exempt)
Full Break Drawbacks
- German property sale may trigger Spekulationssteuer if held under 10 years
- Loss of EUR-denominated real estate asset in a diversified portfolio
- No German base if you return — must rent or buy again
- German rental income provided diversification and EUR exposure — lost on sale
- May miss potential German property appreciation if market rises during UAE years
Partial Break (keep rental property)
- Retain German rental income (EUR-denominated; diversification value)
- Keep a German asset base for return optionality
- Property appreciation continues during UAE years
- DRV pension contributions already accrued; property keeps German economic presence without residency
- Familiarity — existing tenant relationships and property management arrangements
Partial Break Drawbacks
- Annual German tax returns required for rental income (ongoing admin and cost)
- Risk of accidental German tax residency if personal use of property occurs
- German inheritance tax continues to apply to German assets indefinitely (situs rule)
- Mortgage management at distance; currency risk on EUR mortgage if earning AED
- If German property is mortgaged, bank consent required for non-resident status change
Frequently Asked Questions
Frequently Asked Questions
Section 6 AStG (Außensteuergesetz — German Foreign Tax Act) imposes an exit tax when a German tax resident emigrates and held more than 1% of shares in a corporation (GmbH, AG, SE, etc.) at any point in the last 5 years before departure. The tax is calculated on the difference between the market value of the shares on the departure date and their original acquisition cost — even if no actual sale occurred. The deemed gain is taxed at approximately 25% + Solidaritätszuschlag (Kapitalertragsteuer rate). For non-EU/EEA destinations (UAE = non-EU), the full amount is due as a lump sum, without the 7-year installment plan available for EU/EEA emigrants.
No — not without collateral. For emigration to EU/EEA countries, §6(4) AStG allowed interest-free deferral in installments over 7 years. Post-2022 ATAD2 implementation, this is only available for EU/EEA destinations. Moving to the UAE (non-EU) means the full tax is payable, potentially with collateral required by the Finanzamt to secure the liability. Options: (1) Pay the tax in full, (2) Provide acceptable collateral (bank guarantee, asset pledge), (3) Restructure shareholdings before departure (consult adviser urgently — 12–18 months before move), (4) Consider intermediate EU residency step before UAE (complex and requires genuine residency).
Germany's §2 AStG extended limited tax liability applies to German citizens who move to a 'low-tax country' — the UAE qualifies (0% income tax). If you were a German tax resident for at least 5 of the last 10 years before departure, §2 AStG can extend German taxation on certain income types for up to 10 years post-emigration. It applies to income that would not normally be German-source under standard limited tax liability rules but is deemed to have a substantial German economic connection. This is distinct from the standard beschränkte Steuerpflicht on clear German-source income (rental, salary days in Germany, etc.).
The DBA (Doppelbesteuerungsabkommen) between Germany and the UAE entered into force in 2010. It is a bilateral tax treaty following the OECD Model Convention that allocates taxing rights between the two countries to prevent double taxation. Key DBA article allocations: Art. 15 (employment income) → country of work performance; Art. 6 (rental income) → source country (Germany); Art. 10 (dividends) → shared; 5–15% withholding limit; Art. 11 (interest) → residence country; Art. 18 (pensions) → Germany for state pensions; Art. 13 (capital gains) → residence country for most securities (Germany for real property). A UAE TRC confirms you as UAE treaty resident for DBA purposes.
Apply to the UAE Federal Tax Authority (FTA) via their online portal. Requirements: (1) UAE residence visa, (2) Emirates ID, (3) Proof of 183+ days UAE physical presence (entry/exit record from UAE immigration), (4) UAE bank statement, (5) UAE tenancy/lease contract (Ejari registered), (6) Employer letter or UAE trade licence for business owners, (7) Passport copy. FTA review takes 4–8 weeks. Fee: AED 1,000 for individuals. The TRC is issued per calendar year. For the Germany-UAE DBA, the TRC is submitted to your German Finanzamt with an official cover letter to establish UAE treaty residency. Re-apply each year you need a TRC.
No — if you have genuinely broken German tax residency and are a UAE tax resident. Under DBA Article 15, employment income is taxable in the country where the work is physically performed. Since you are physically working in Dubai (UAE), your Dubai salary is taxed in the UAE — where the rate is 0%. Germany has no right to tax your Dubai salary under the DBA. Critical conditions: (1) You have formally deregistered in Germany (Abmeldung done), (2) You have no German Wohnsitz (no personally-used German property), (3) You spend fewer than 183 days in Germany, (4) You have a UAE TRC. If any of these conditions are not met, the Finanzamt may challenge your residency position.
German rental income is taxable in Germany regardless of where you live. DBA Article 6 assigns the right to tax real property income to the country where the property is situated — Germany. As a non-resident, you are beschränkt steuerpflichtig (limited tax liable) in Germany on rental income. You file an annual German Einkommensteuererklärung (tax return) declaring the rental income. You can deduct: mortgage interest, maintenance costs, management fees, Grundsteuer (property tax), insurance, and Abschreibung (depreciation: 2%/yr pre-2023 buildings, 3%/yr newer). Net income is then taxed at German progressive rates, with the personal allowance partially accessible for non-residents from DBA countries (EUR 11,604 in 2026).
The DRV (Deutsche Rentenversicherung) state pension is earned based on years of contribution and is fully portable internationally. While in Dubai, you do not make further DRV contributions (your UAE employer does not contribute to German pension). Existing contribution years remain fully vested. When you reach the pension age (67 for full pension; 63/65 for reduced), the DRV pays your pension to any bank account worldwide. German state pension income is taxable in Germany under DBA Article 18 — even while you live in UAE. The taxable portion is 83–100% depending on year of retirement (fully 100% from 2040). File a German tax return for pension years.
German inheritance tax (Erbschaftsteuer) has a 5-year tail rule for emigrants: if you were a German tax resident within the 5 years before an inheritance event, German inheritance tax can apply. During those 5 years in Dubai, German inheritance tax may apply to: (1) German assets inherited by you, and (2) Inheritances FROM you to German-based heirs. After the 5-year post-emigration period, German inheritance tax applies only to German-situs assets (German property, German business interests) — not to UAE assets or other non-German assets. The German spouse/child allowance of EUR 400,000–500,000 still applies. Tax rate: 7–30% (Class I family) above the allowance.
Kapitalertragsteuer (KeSt) is Germany's capital gains and investment income withholding tax at 25% + Soli (~26.375%). German banks automatically withhold KeSt on dividends from German companies, German-source interest, and capital gains on German securities. As a UAE tax resident, you can apply for a reduced withholding rate under the DBA — typically 5–15% for dividends depending on shareholding percentage (DBA Art. 10). File a Freistellungsantrag with your German bank. Excess withholding can be reclaimed via German tax return. Note: §6 AStG exit tax uses Abgeltungsteuer rate (25% + Soli) for deemed disposal calculation.
Only if you have German-source income. If you have sold your German property, have no German rental income, no German pension, no German employment days, and no German dividends — and have fully broken German tax residency — then no German return is required. Most German Dubai expats DO have ongoing German obligations: German rental income (most common), German pension once drawing, German work visits. File an Einkommensteuererklärung annually via ELSTER or via your German Steuerberater. Late filing attracts Verspätungszuschlag (surcharges). The Finanzamt retains jurisdiction over German-source income indefinitely.
The DBA residency tie-breaker applies when both Germany and UAE could claim an individual as tax resident. The sequential test: (1) Where do you have a permanent home? (2) Where is your centre of vital interests (personal and economic relations)? (3) Where is your habitual abode (where you spend more time)? (4) Which nationality applies? In practice: if you have a German property (Wohnsitz), a German spouse and children still in Germany, and your primary employer is German, the Finanzamt may argue Germany is your centre of life interests — even if you have a UAE lease and TRC. Genuinely moving your family to Dubai, surrendering or commercially renting your German property, and demonstrating UAE economic integration is the strongest position.
German Spekulationssteuer (speculation tax) applies to capital gains on properties sold within 10 years of acquisition — unless it was your primary residence for the 3 years preceding sale or the year of sale and the 2 preceding calendar years. If you have owned your German property for less than 10 years and it was a rental/investment property, selling before departure avoids the complexity of non-resident sale but may trigger Spekulationssteuer. If you have held it 10+ years, 0% Spekulationssteuer applies whenever you sell (as a resident or non-resident). Strategy: if close to the 10-year mark, wait. If primary residence and living in it up to departure, the 3-year primary residence exemption may apply. Consult your Steuerberater for the calculation.
Germany has broad international information exchange via the Common Reporting Standard (CRS). UAE banks report account information annually to UAE authorities, which then share with Germany (and other CRS signatory countries) for German-identified account holders. So the Finanzamt can see UAE bank account balances and income. However, Germany can only tax income that is German-source or covered by the extended limited tax liability under §2 AStG — the Finanzamt cannot simply tax UAE-earned income because they can see your UAE bank balance. The CRS data exchange is most relevant for identifying unreported German-source income being deposited abroad, not for taxing UAE-source income.
To defend genuine UAE tax residency against Finanzamt challenge, maintain: (1) UAE TRC (issued annually by FTA — apply every year you need DBA protection), (2) UAE residence visa + Emirates ID (photocopies with dates), (3) UAE bank statements showing regular activity, (4) UAE lease contract (Ejari registered), (5) UAE employer payslips or invoices if business owner, (6) Travel records — passport stamps + airline boarding passes showing 183+ UAE days and under 183 German days, (7) UAE utility bills, gym memberships, club memberships (evidence of habitual abode), (8) German Abmeldung certificate (deregistration confirmation from municipality). The burden of proof in a Finanzamt challenge lies with you to demonstrate genuine UAE residency.
