The German Exit Tax (Wegzugsteuer)

Section 1 — The Three-Part Trigger Test & Realization Events Under §6 AStG

The German exit tax does not apply automatically to everyone with assets who travels abroad. For §6 AStG (Außensteuergesetz — § 6 AStG PDF) to take effect, two threshold criteria (duration and shareholding under § 17 EStG PDF) must be met, and a statutory realization event must occur. If any single condition is absent, the exit tax cannot be lawfully levied.

The 5-Year Look-Back on Shareholdings: Note the statutory trap in Condition 2. Even if your equity stake was diluted to 0.75% during a recent venture capital funding round, you remain subject to exit tax if you held 1.0% or more at any point in the 5 years preceding the realization event. Furthermore, the shares do not need to be in a German entity; equity in Delaware C-Corps, UK Limited companies, French SAS, or Dutch BVs is equally captured if held by a qualifying German tax resident.

The Three Statutory Realization Events Under §6 Abs. 1 AStG: Merely having lived in Germany for 8 years and holding 25% of a GmbH does not trigger exit tax if you continue living in Berlin or Munich. Under §6 Abs. 1 AStG, exit tax requires one of three specific realization events:

• 1. Termination of Unlimited Tax Liability (§6 Abs. 1 No. 1 AStG): You terminate German unlimited tax liability by relinquishing both your German domicile (Wohnsitz under §8 AO) and your habitual abode (gewöhnlicher Aufenthalt under §9 AO).
• 2. Gratuitous Transfer to a Non-Resident (§6 Abs. 1 No. 2 AStG): You gift or bequeath qualifying shares to an individual or entity that is not subject to German unlimited tax liability.
• 3. Restriction or Exclusion of Germany's Taxing Right (§6 Abs. 1 No. 3 AStG): Any transaction, restructuring, or event—including treaty residence shift under a double taxation treaty tie-breaker—that results in Germany losing or restricting its right to tax future capital gains upon an actual disposal of the shares.

Section 2 — How the Exit Tax Is Calculated (§17 EStG & Progressive Rates)

Unlike a conventional capital gains tax assessed upon a cash sale, §6 AStG creates a legal fiction. On the date unlimited tax liability terminates, the law deems the shares to have been sold at fair market value (gemeiner Wert) pursuant to §9 BewG (Bewertungsgesetz).

The Partial-Income Method (Teileinkünfteverfahren)

Because the deemed disposition of corporate shares falls under the shareholder capital gains rules of §17 EStG (PDF), the tax base is governed by the Teileinkünfteverfahren (§3 Nr. 40 Buchst. c and §3c Abs. 2 EStG):

• 60% of the deemed capital gain (Fair Market Value minus adjusted tax acquisition costs) is subject to income tax.
• 40% of the deemed capital gain is completely exempt from income tax.

The taxable 60% is taxed at the individual's progressive income tax rate under §32a EStG, plus the 5.5% solidarity surcharge (Solidaritätszuschlag) calculated on the income tax amount.

Case Study: The €10,000,000 Startup Valuation (Maximum Rate Illustration)

Consider Marcus, co-founder of a Munich B2B SaaS company. Marcus owns a 50% equity stake in a GmbH with original share capital and acquisition costs of €25,000. Prior to his planned move to Dubai, the fair market value of the GmbH is determined to be €10,000,000 based on standard valuation principles under the Valuation Act.

Marcus faces a personal tax assessment from the Finanzamt of over €1.41 million, despite not selling a single share or receiving secondary liquidity from the company.

Section 3 — The 2022 ATAD Reform: Uniform 7-Year Installments & Security

A central reason why older tax guidance is unreliable today is the fundamental statutory overhaul introduced by the ATAD Implementation Act (ATAD-Umsetzungsgesetz), effective January 1, 2022.

The Statutory Installment Framework (§6 Abs. 4 AStG) & Security (§241 AO)

Under §6 Abs. 4 AStG (PDF), the assessed exit tax may, upon timely application, be paid in seven equal annual installments without interest. However, the statute establishes a clear default rule regarding security: "Die Stundung erfolgt in der Regel gegen Sicherheitsleistung" (security is generally to be demanded under §241 AO).

For founders whose wealth is concentrated in early-stage or illiquid private company shares, satisfying this requirement can be challenging. Commercial banks typically do not issue unconditional bank guarantees against non-public shares, and tax authorities regularly decline share pledges in private corporations due to liquidity constraints and valuation volatility. Taxpayers may therefore be required to pledge cash, marketable securities, or unencumbered real estate to secure installment relief.

Statutory Revocation Triggers (Widerruf under §6 Abs. 4 S. 5 AStG)

Even when granted installment relief, the remaining unpaid balance becomes immediately due and payable in full if any of the statutory revocation events occur:

• Failure to pay any annual installment within one month of its statutory due date.
• Subsequent sale, transfer, or liquidation of the shares.
• Capital repayments or distributions exceeding 25% of the company's value.
• Failure to satisfy mandatory annual notification requirements under §6 Abs. 5 AStG.
• Opening of insolvency proceedings over the taxpayer's assets.

Section 4 — The Investment Fund Regime (§19 & §20 InvStG) & Asset Clarifications

Under §19 Abs. 3 InvStG (Investmentsteuergesetz), the German legislature established a parallel deemed-disposal regime specifically targeting private holdings in investment funds, ETFs, and collective investment vehicles.

Statutory Fund Partial Exemptions (Teilfreistellung under §20 InvStG)

For private investors, §20 InvStG grants partial tax exemptions depending on the fund's continuous investment focus, directly reducing the taxable deemed gain:

Asset Classification: What Is Caught vs. What Is Exempt

One of the most frequent misconceptions is that an entire personal balance sheet is taxed upon departure. It is critical to distinguish corporate equity and qualifying funds from exempt personal assets:

Section 5 — Destination Nuances: EU/EEA vs. Third Countries & Switzerland

Under the current statutory framework of §6 Abs. 4 AStG, the 7-year annual installment mechanism applies uniformly regardless of whether you relocate to an EU/EEA member state or a third country. However, significant practical differences exist in administrative security enforcement and bilateral treaty application.

Section 6 — Reporting Requirements (§6(5) AStG) & Compliance Exposure

Departing Germany without formally addressing exit tax obligations creates substantial exposure. German tax authorities maintain specialized international tax audit units and receive automated financial information under multilateral reporting standards.

Statutory Disclosure & Ongoing Notification Obligations

Compliance involves both initial tax return reporting and ongoing post-exit notification duties:

• Initial Tax Return Filing: The deemed capital gain must be disclosed in the annual German income tax return for the departure year, accompanied by compliant valuation documentation establishing fair market value at the exit date.
• Annual Status Declaration (§6 Abs. 5 AStG): Following a qualifying §6 event, the taxpayer or universal successor must submit the required annual notification by July 31 of each calendar year, reporting the current address and confirming continued attribution of the shares (PDF).
• One-Month Event-Triggered Notification (§6 Abs. 5 S. 4 AStG): Taxpayers must affirmatively notify their responsible German tax office within one month of specific statutory events:
  • The sale, transfer, redemption, or liquidation of the qualifying shares;
  • Capital reductions, repayments, or profit distributions exceeding 25% of the company's value; or
  • The termination of foreign residence without re-establishing German unlimited tax liability.

Section 7 — The Valuation Date: Timing, Valuation Methods & Presence Evidence

In the German exit tax regime, the exact moment unlimited tax liability terminates is not a minor administrative detail: it is the statutory valuation date that legally anchors the deemed sale price and dictates your tax liability.

Under §6 Abs. 1 S. 1 AStG, the deemed sale takes place "im Zeitpunkt der Beendigung der unbeschränkten Steuerpflicht" — at the precise moment unlimited tax liability ceases.

Statutory Valuation Hierarchy Under §11 BewG

Valuation of corporate shares without a public market listing follows the statutory hierarchy set forth in §11 BewG (Bewertungsgesetz):

When Does Unlimited German Tax Liability Actually Terminate?

When filing an exit tax return, the tax authority does not simply accept a self-declared date or a municipal deregistration certificate (Abmeldebestätigung). Under German fiscal jurisprudence, termination of unlimited tax liability is governed by factual circumstances under the Fiscal Code:

• Surrender of Domicile (Wohnsitz under §8 AO): Unlimited liability persists as long as a dwelling in Germany remains available for personal use under circumstances indicating it will be retained. Retaining keys, access to furnished rooms, or sub-leasing arrangements where personal access is preserved can prevent the legal termination of Wohnsitz.
• Severance of Habitual Abode (gewöhnlicher Aufenthalt under §9 AO): Under §9 AO, habitual abode is established where an individual stays under circumstances indicating a presence that is not merely temporary. A continuous stay of more than six months establishes habitual abode from the beginning (with short interruptions disregarded). Physical departure must represent a genuine, continuous severance of physical connection.

Documenting Your Departure Timeline with Domicile365

Because exit tax audits typically take place two to four years after departure, reconstructing a historical timeline using ad-hoc receipts, boarding passes, or calendar entries is often fraught with gaps.

Domicile365 provides structured, contemporaneous documentation of your physical presence and absence to substantiate your factual departure timeline alongside your lease terminations, deregistration, and treaty tie-breaker evidence:
