1. The "Progression Trap" (Progressionsvorbehalt)
The most misunderstood concept. Under the DTAA, Indian Rental Income is "Exempt" from German tax, BUT it is added to your German income to determine your Tax Rate.
How it works
1. Finanzamt calculates your theoretical tax rate on (German Salary + Indian Rent).
2. They apply that higher rate solely to your German Salary.
Base German Salary: €60,000
2. Kapitalertragsteuer (Flat Tax)
Investment Income (NRE Interest, Dividends, Capital Gains)
Investment income is taxed separately from your salary at a flat rate. Indian "Tax-Free" NRE interest is FULLY TAXABLE here.
3. Income Matrix (DTAA)
German Salary
💶Germany: Fully Taxable.
India: Exempt.
NRE Interest
🏦Germany: Taxable (26.38%).
India: Tax Free.
Indian Rent
🏠Germany: Exempt (Article 6 DTAA).
Progression: Increases rate on other income.
The "Kirchensteuer" Warning
If you declared yourself as Catholic, Protestant, or Jewish during city registration (Anmeldung), 8% or 9% of your income tax liability is added as Church Tax.
If your Income Tax is €10,000:
+ Soli (5.5%): €550
+ Church (9%): €900
Total Tax: €11,450
