Leaving Germany: when the Finanzamt lets go.

Germany mostly taxes residence, not citizenship — which sounds simple until you learn what counts as “still resident,” and which rules can follow you for a decade. The high-level map, in plain language.

The two switches: unlimited vs limited liability

While you have a Wohnsitz (a home at your disposal, § 8 AO) or a gewöhnlicher Aufenthalt (habitual abode, § 9 AO) in Germany, you're under unbeschränkte Steuerpflicht — unlimited liability, taxed on worldwide income. Give both up, and you generally drop to beschränkte Steuerpflicht — taxed only on German-sourced income like German rent or business profits.

The trap: this turns on facts, not paperwork. Abmeldung is required — § 17(2) BMG gives you two weeks from moving out — but keeping a key to a flat that's yours to use can keep a Wohnsitz alive regardless of what you deregistered. The room at your parents' house is a genuinely debated example.

The ten-year shadow: extended limited liability (§ 2 AStG)

German citizens who move to a low-tax country can face erweiterte beschränkte Steuerpflicht for up to ten years after leaving — if they were under unlimited liability for at least five of the ten years before departure and keep substantial economic interests in Germany. Popular nomad bases with low or zero income tax are exactly the destinations this rule was written for.

Exit tax on shareholdings (§ 6 AStG)

Hold a significant stake in a company (broadly, 1%+ in a corporation) when you emigrate, and Germany may tax the unrealised gain — the difference between what your shares cost and what they're worth the day you leave — as if you'd sold. Founders and startup employees with equity should price this in before booking the flight.

What's still due after you leave

2 Aug 2027 — Einkommensteuererklärung for 2026, if you file yourself (§ 149(2) AO; 31 July 2027 is a Saturday, § 108 AO moves it to the next working day). German-source income, rental income above all, generally keeps the obligation alive after you leave.
29 Feb 2028 — the later date when a Steuerberater files for you (§ 149(3) AO). Transitional extensions have applied in recent years; confirm the year's actual date before relying on it.
Within 2 weeks of moving out — Abmeldung (§ 17(2) BMG). The Abmeldebescheinigung is what banks, insurers and the Finanzamt ask for as proof you actually went.
Voluntary returns — where you're not obliged to file, a four-year retroactive window applies, and it's often worth a refund.

The German deadline dashboard keeps these counted down, with the statutory source next to each date.

Informational only — not tax, legal, or immigration advice. General rules as checked on the date above; deadlines can shift and individual circumstances differ. This is a simplified overview of genuinely complex law (AO and AStG provisions, double-tax treaties and case law all apply). Anyone with property, shareholdings, or a low-tax destination should speak to a Steuerberater before moving.

Leaving well is a checklist, not a vibe.
