Expat Tax Residency in Germany

Germany's two residency tests

Germany determines tax residency for individuals through TWO alternative tests under the Abgabenordnung (AO, Fiscal Code). Satisfying EITHER ONE makes the individual an unlimited German tax filer (unbeschränkt steuerpflichtig):

• Wohnsitz (domicile) under §8 AO: A dwelling held under circumstances suggesting that the filer will retain and use the dwelling. Facts-and-circumstances test focusing on whether the filer has a place that is available for use as a residence (not necessarily their main residence). Even a holiday home or family-shared dwelling can constitute Wohnsitz if available for the filer's use.
• Gewöhnlicher Aufenthalt (habitual abode) under §9 AO: Continuous presence in Germany generally exceeding 6 months (with brief interruptions of less than 6 weeks disregarded as 'temporary'). The 6-month threshold is the primary trigger, though shorter periods with consistent return patterns may also qualify.

The two-test framework is conceptually parallel to the UK's pre-2013 'ordinarily resident' framework and SA's ordinarily-resident + physical-presence tests — but uses German-specific quantitative thresholds.

Wohnsitz is the sticky test:

• Once Wohnsitz is established, it continues until the dwelling is genuinely abandoned. Physical absence from Germany doesn't automatically terminate Wohnsitz if the dwelling remains available.
• Maintaining a German Wohnung available for personal use (even with family members in residence) can preserve Wohnsitz even after the filer has physically relocated.
• Selling or letting the dwelling on a long-term basis (typically 12+ months) typically extinguishes Wohnsitz.

Gewöhnlicher Aufenthalt is the temporary-presence test:

• Activated when continuous presence exceeds 6 months.
• Common scenario: foreign assignees relocating to Germany typically acquire gewöhnlicher Aufenthalt upon crossing the 6-month threshold.
• Lost when the filer leaves Germany permanently.

Resident vs non-resident tax treatment

Unbeschränkte Steuerpflicht (Unlimited Tax Liability) — for German tax residents under §1(1) EStG:

• Taxed on WORLDWIDE income at progressive marginal rates 0% (Grundfreibetrag €11,604) to 45% (Reichensteuer above €277,825 single, €555,650 joint).
• Plus 5.5% Solidaritätszuschlag (scaled back from 2021, most filers no longer pay).
• Plus 8-9% Kirchensteuer if registered with religious community.
• Access to all German credits, deductions, and special-allowances (Sparer-Pauschbetrag, working-from-home deduction, child allowances).

Beschränkte Steuerpflicht (Limited Tax Liability) — for non-residents under §1(4) EStG:

• Taxed only on German-source income (Inlandseinkünfte) listed in §49 EStG: German employment income, German rental income, German business income, German capital gains on German real estate or substantial German shareholdings, German dividends/interest (subject to withholding only).
• No Grundfreibetrag — taxable from first euro.
• No standard credits (Sparer-Pauschbetrag, etc.) — limited treaty-based exceptions.
• Withholding tax often final (Abgeltungsteuer on dividends, 25% on royalties + Soli).

§1(3) EStG election (Antrag auf unbeschränkte Steuerpflicht):

• Available to non-residents where 90% or more of their worldwide income is German-source (typical for cross-border commuters from neighbouring EU states).
• Allows access to Grundfreibetrag, joint married assessment, and other resident-treatment benefits.
• Particularly used by commuters from Belgium, France, Luxembourg, Netherlands working in Germany.

The Wegzugsteuer — §6 AStG exit tax

Germany imposes an exit tax under §6 of the Außensteuergesetz (AStG) when a tax resident ceases German residency. This is the German equivalent of Australia's CGT event I1 and Canada's deemed-disposition-at-emigration.

Triggering conditions:

• The filer has been an unbeschränkter Steuerpflichtiger (German tax resident) for at least 7 of the prior 12 years.
• The filer holds a 'wesentliche Beteiligung' (significant shareholding) — at any time during the prior 5 years, held ≥1% of an unlisted company OR ≥1% of a listed company in business assets.
• The filer ceases unbeschränkter Steuerpflichtiger status.

Tax calculation:

• Hidden reserves (stille Reserven) are treated as fictitious disposal at fair market value on the date of cessation.
• Capital gain = FMV at cessation MINUS historical cost base.
• Standard CGT rates apply: §17 EStG framework for substantial shareholdings (Teileinkünfteverfahren — 60% of gain included in income at progressive marginal rates).

Deferral / payment options:

• EU/EEA emigration (post-2022 reform): Interest-free deferral without time limit until actual disposal of the shares. Material relief — preserves liquidity for genuine EU intra-Union mobility.
• Non-EU emigration: Payment staggered over 7 years (post-2022 reform from the prior immediate-payment requirement). Interest-bearing deferral.

The 2022 reform substantially improved the Wegzugsteuer framework — particularly the interest-free EU/EEA deferral. Pre-2022, the framework was widely criticised as restricting EU free movement.

For a filer holding €5 million of hidden reserves in a German GmbH at cessation of residence:

• Hidden reserves: €5,000,000.
• Teileinkünfteverfahren 60% inclusion: €3,000,000.
• Marginal rate ~45% + Soli + Kirche: ~€1,350,000 tax.
• EU-bound: interest-free deferred until actual disposal.
• Non-EU bound: 7-year staggered payment.

§2 AStG extended limited tax liability

The Außensteuergesetz §2 'Erweiterte beschränkte Steuerpflicht' (Extended Limited Tax Liability) targets perceived tax-flight by high-net-worth Germans relocating to low-tax jurisdictions:

Triggering conditions:

• The filer was unbeschränkt steuerpflichtig in Germany for at least 5 of the prior 10 years prior to departure.
• The filer relocates to a Niedrigsteuerland (low-tax country) — defined as a jurisdiction where the filer's income would be taxed at less than 2/3 of the corresponding German tax burden.
• The filer retains 'wesentliche wirtschaftliche Interessen' (substantial economic interests) in Germany — typically defined by income or wealth thresholds.

Tax consequences:

• German-source income remains taxable in Germany at progressive rates (not just withholding) for 10 years after departure.
• Worldwide foreign-source income remains subject to German tax where it would have been taxable for an unbeschränkter resident — material extension beyond ordinary non-resident treatment.
• After the 10-year period, ordinary non-resident treatment resumes.

Targeted jurisdictions: Traditionally targeted Monaco, UAE, Bahamas, certain Swiss cantons. Post-2017 OECD BEPS framework has narrowed the universe of qualifying low-tax jurisdictions.

The §2 AStG framework remains controversial — particularly within EU/EEA contexts where free-movement principles arguably conflict with the extended liability. ECJ jurisprudence has narrowed the framework's application to non-EU departures.

US-Germany tax treaty and the Saving Clause

The US-Germany tax treaty (1989, amended by 2008 protocol) preserves US citizenship-based taxation via Article 1(4) Saving Clause:

• Article 4 Residence: Standard OECD tie-breaker for individuals.
• Article 10 Dividends: 0% for substantial-holding US pension funds (5%+ ownership in qualifying institutional shareholder); 5% for substantial corporate shareholders (10%+ ownership); 15% for portfolio dividends.
• Article 11 Interest: 0% for most categories (qualifying institutional investors, government).
• Article 12 Royalties: 0% for most industrial categories.
• Article 13 Capital Gains: Generally allocated to residence state; real-property gains taxable where situated.
• Article 18 Pensions: Carved out from Saving Clause — preserves source-state primary taxing rights.
• Limitation on Benefits (LOB): Article 28 — detailed LOB clause reflecting US treaty practice.

For US-citizen German residents:

• Dual filing required: Einkommensteuererklärung to Finanzamt + Form 1040 to IRS.
• Form 1116 Foreign Tax Credit prevents double taxation on overlapping income.
• Form 8938 (FATCA) for non-US accounts above thresholds.
• FBAR (FinCEN 114) for non-US accounts exceeding USD 10,000 aggregate.
• Form 8833 treaty disclosures for treaty-claimed positions.

The substantial US-German dual-resident population (US service members, US-citizen professionals working in Germany, US expat retirees) makes US-Germany compliance a frequent practitioner specialty.

Compliance via Einkommensteuererklärung

German residency compliance follows the standard self-assessment framework:

• Mantelbogen + Anlagen: The annual Einkommensteuererklärung includes the main form (Mantelbogen) plus specific Anlagen (annexes) for different income types.
• Anlage AUS: For foreign income reporting and foreign tax credit claims.
• Anlage WA-ESt: For substantial-shareholding interests and §6 AStG Wegzugsteuer reporting.
• Wegzugsanzeige: Formal notification of cessation of residence — filed with Finanzamt within reasonable time after departure.
• Elster online portal: Mandatory for most categories. Deadline 31 July (or end-February of second-following year with Steuerberater).

Split-year reporting for the year of arrival or departure:

• Resident period: worldwide income on Anlage AUS + standard credits and deductions.
• Non-resident period: German-source income only.
• Two separate annual assessments under specific procedural rules.
