How Tax Calculation Works

Income tax is calculated on your total taxable income after deducting eligible exemptions and deductions from your gross income. The tax is applied progressively — you pay a lower rate on initial income slabs and higher rates only on income that exceeds each threshold. This means moving into a "higher tax bracket" does not mean your entire income is taxed at the higher rate. Understanding marginal vs effective tax rate is crucial: your marginal rate applies only to the last rupee earned, while your effective rate is the average across all slabs.

Tax-Saving Strategies

Under the old regime, maximize deductions: Section 80C allows up to Rs 1.5 lakh through PPF, ELSS, EPF, and life insurance. Section 80D covers health insurance premiums up to Rs 25,000 (Rs 50,000 for senior citizens). Section 80CCD(1B) offers an additional Rs 50,000 deduction for NPS contributions. Home loan interest up to Rs 2 lakh is deductible under Section 24. Under the new regime, the Rs 75,000 standard deduction and lower slab rates may save you more if your total deductions are below Rs 3.75 lakh. Calculate under both regimes before choosing.

German Income Tax Rates and the 2026 Grundfreibetrag

German income tax (Einkommensteuer) follows a progressive tariff defined in § 32a EStG. For 2026 the Grundfreibetrag — the tax-free basic allowance — is EUR 12,348 for singles (EUR 24,696 for jointly assessed couples), up from EUR 12,096 in 2025. The allowance is re-indexed almost every year based on the government's Existenzminimumbericht, so treat the 2026 figure as legislated as of mid-2026 and check the Bundesministerium der Finanzen (BMF) for any later adjustment. Above the allowance, marginal rates start at 14% and climb through two progression zones until the 42% top rate begins at roughly EUR 69,900 of taxable income (also indexed annually). The 45% "Reichensteuer" applies from EUR 277,826, a threshold that has stayed fixed for years. Worked example: a single person with EUR 50,000 taxable income owes roughly EUR 10,700 income tax under the 2025 tariff — an average rate near 21% and a marginal rate of about 35.5%; the 2026 tariff shifts the brackets slightly, so expect marginally less. On top of that, the 5.5% solidarity surcharge (Solidaritätszuschlag) applies only when income tax exceeds an exemption of EUR 20,350 for singles in 2026 (EUR 19,950 in 2025, indexed annually), which spares around 90% of taxpayers entirely. Church members additionally pay Kirchensteuer of 8% or 9% of their income tax. Returns are filed with the Finanzamt through ELSTER.

Tax Classes I–VI and How Married Couples Split

Germany's six wage tax classes (Steuerklassen) determine only how much Lohnsteuer your employer withholds each month — not your final annual bill. Class I applies to singles; class II to single parents, adding the Entlastungsbetrag für Alleinerziehende of EUR 4,260 plus EUR 240 per additional child (as of mid-2026); classes III and V suit married couples with one dominant earner (III withholds using both basic allowances, V almost none); IV/IV is the default equal split for spouses, optionally with a factor that pro-rates the splitting advantage; class VI covers second jobs and withholds the most. Married couples are ultimately taxed under Ehegattensplitting: joint taxable income is halved, the tariff applied, and the result doubled. Example under the 2025 tariff: EUR 80,000 earned entirely by one spouse costs about EUR 22,700 as a single filer, but only about EUR 14,600 with splitting — an advantage close to EUR 8,000. Two spouses each earning EUR 40,000 gain nothing extra, since splitting then equals their individual results. Because classes III/V only front-load that advantage into monthly pay, couples using them are generally required to file an annual Einkommensteuererklärung, where the Finanzamt settles the true liability. The governing coalition has announced plans to fold classes III/V into IV-with-factor later this decade; as of mid-2026 nothing has changed. Kirchensteuer withholding (8% in Bavaria and Baden-Württemberg, 9% in other Länder) also runs through your tax class.
