Germany Expats in Portugal — Tax Guide 2026

By Taxpert Editorial · Last reviewed: 26 April 2026

Germany is a major source of expats moving to Portugal, particularly tech professionals, entrepreneurs, and retirees. Germany has one of Europe's most comprehensive exit tax regimes, meaning leaving can trigger significant German tax obligations on unrealized gains. Understanding this before relocating is critical. The Germany-Portugal DTT (1980) provides solid treaty protection for ongoing income.

Double Taxation Treaty: Yes (1980)
Tax relief mechanism: Treaty FTC

Key facts

Income type treatment

Employment

German-source employment: If working remotely for a German employer, Germany taxes the Germany-source income under treaty Article 15. Portugal also taxes as worldwide resident. FTC applied in Portugal for German withholding. If employment is Portuguese-source, only Portugal taxes — IFICI 20% flat rate may apply.

Pension

German statutory pension (DRV): Under the treaty, both Germany and Portugal may tax. Germany withholds at source (typically 15–25% after allowances). Portugal taxes as Cat. H at progressive rates with FTC for German tax. Company and private pensions: Portugal has taxing rights; German withholding varies. Former NHR Legacy holders with German pensions enjoyed 10% flat — IFICI does not replicate this.

Dividends

German dividends: Portugal taxes at 28%; Germany applies 25% Abgeltungsteuer (capital gains tax) at source. Treaty reduces withholding to 15%. FTC in Portugal for German withholding. High combined burden — optimize by aggregating if Portuguese marginal rate is low.

Rental income

German rental income: Germany has taxing rights under the treaty (property location rule). Portugal also taxes as Cat. F. German tax acts as FTC in Portugal, usually fully offsetting the Portuguese Cat. F tax.

Capital gains

German securities: Portugal 28%; Germany Abgeltungsteuer 25% at source — FTC applies. German real estate held <10 years: Germany taxes (Spekulationssteuer). Portuguese real estate: Portugal taxes under normal rules.

Watch-outs for Germany expats

⚠

Exit tax (Wegzugsbesteuerung): If you own >1% of a German company, Germany may assess tax on unrealized gains in shares at departure. This can be deferred in EU/EEA moves (Portugal is EU) but must be formally managed — file the German exit declaration.

⚠

Ongoing German tax obligation: Germany may continue to have limited tax jurisdiction on certain Germany-source income (pensions, rental, royalties) even after you become Portuguese-resident.

⚠

Kirchensteuer (church tax): Leaving Germany and deregistering properly (Abmeldung) is required to stop church tax liability. Ensure you formally deregister from the German municipality and the church if applicable.

⚠

German pension complexity: The German statutory pension calculation is based on Entgeltpunkte and can be affected by whether contributions are recognized across countries. The Germany-Portugal Social Security Agreement coordinates benefit entitlements.

⚠

German Riester/Rürup pensions: These products have special German tax treatment that Portugal does not recognize — gains and withdrawals may be fully taxable in Portugal.
