Work and tax in Germany — Steuer-ID, Lohnsteuer, and the Lohnabrechnung

The Steuer-ID and the Lohnsteuer system

Your Steuer-Identifikationsnummer (Steuer-ID) is your lifelong tax ID — 11 digits, issued by the Bundeszentralamt für Steuern automatically a few days after your Anmeldung. Give it to your employer immediately; without it, payroll runs at the highest tax bracket (Steuerklasse VI / 6) until it arrives, often costing you €500–2,000 in extra tax that takes months to claw back through a Steuererklärung.

Income tax is deducted monthly via Lohnsteuer (wage tax) — your employer calculates the deduction based on your tax class and pays it to the Finanzamt (tax office). At year-end you can file an annual Steuererklärung to reclaim deductions; for most employees this returns €1,000–1,500 on average.

Steuerklassen — the six tax classes

Married couples pick III/V (higher earner gets III, lower V) for higher monthly take-home but a likely top-up at year-end, or IV/IV for more even monthly cash flow. The III/V split saves nothing in total tax — only changes the timing — but the cash flow can matter. Switching is once per year via the Finanzamt.

• I — single without children, divorced, separated. The default for most newcomers.
• II — single parents (with at least one child living with them).
• III — married, where the spouse is in IV or VI; the higher-earning partner usually picks III.
• IV — married, both partners earn similar amounts (default for newly married).
• V — married, where the spouse is in III; pairs with III.
• VI — second job, freelance income on top of a main job, or no Steuer-ID on file.

Income tax bands (2024 / 2026 indicative)

Germany uses a progressive income-tax curve, not flat bands. Up to €11,604/year is the Grundfreibetrag (zero tax). Marginal rates rise smoothly from 14% (just above the threshold) to 42% (at €66,761), then 45% on income above €277,826. The exact thresholds are reset annually for inflation.

On top of income tax: a Solidaritätszuschlag (5.5% of the income tax, payable by high earners — most people no longer pay it after 2021 reform) and Kirchensteuer (church tax, 8–9% of income tax for declared members of a recognised church — mostly Catholic and Protestant). You pay no Kirchensteuer if you opt out at the Anmeldung or formally leave a church via your local Standesamt.

Social contributions on top of income tax

A typical office worker on €60k gross per year takes home around €3,200/month after all deductions — about a 36% effective burden including income tax. Top earners hit a marginal effective rate around 50%; salary increases above the social-contribution caps go further than below.

• Krankenversicherung (health insurance) — ~14.6% + Zusatzbeitrag (~1.7%), split with employer. Capped at €5,512.50/month income (Beitragsbemessungsgrenze, 2026).
• Rentenversicherung (pension) — 18.6%, split with employer.
• Arbeitslosenversicherung (unemployment) — 2.6%, split with employer.
• Pflegeversicherung (long-term care) — 3.4–4% (higher for the childless), split with employer.
• Total employee share of social contributions: ~21–22% of gross salary up to the income cap.

Reading a Lohnabrechnung

Your monthly Lohnabrechnung (payslip) lists: Bruttolohn (gross salary), Lohnsteuer (income tax), Solidaritätszuschlag, Kirchensteuer (if applicable), Krankenversicherung-Arbeitnehmer, Rentenversicherung-Arbeitnehmer, Arbeitslosenversicherung, Pflegeversicherung, plus any voluntary deductions (additional pension, betrieblicher Vorteil benefits). The Nettolohn (net) is what hits your bank account.

Employer-side contributions (Arbeitgeberanteil) are listed for transparency but do not affect your net. The total cost of an employee to the employer is roughly 1.2–1.3x the gross salary; useful when negotiating.

The annual Steuererklärung

For most employees the Steuererklärung is optional, but worth filing — average refund is €1,000–1,500. Deadline: July 31 of the following year (for self-prepared); September 30 if using a Steuerberater (tax advisor) or commercial software.

Common deductions: commute (Pendlerpauschale, €0.30 per km up to 20km, €0.38 above), home office (Homeoffice-Pauschale of €6/day, max 1,260/year), professional expenses (Werbungskosten — work-related courses, equipment, professional memberships), donations, and exceptional medical / dependent-care costs.

Filing options: the official ELSTER online portal (free, somewhat clunky), commercial software (WISO Steuer, smartsteuer, taxfix at €30–50 per year), or a Steuerberater (€200–800 for a typical return; mandatory if you have rental, freelance, or international income above thresholds).

Self-employment, freelance, and Kleinunternehmer

Self-employed and freelance (Selbstständig / Freiberufler) workers register with the Finanzamt via the Fragebogen zur steuerlichen Erfassung. You file annual income tax and Umsatzsteuer (VAT, 19%) returns; the Kleinunternehmerregelung lets revenues under €25,000/year skip VAT collection at the cost of not being able to claim VAT back on expenses.

Self-employed must arrange health insurance privately (or stay in voluntary public coverage) — there is no employer share. Pension is optional for most; some categories (artists, journalists via Künstlersozialkasse) have mandatory contributions at subsidised rates.

Limited companies (GmbH, UG) require €25,000 / €1 minimum capital respectively, plus annual Bilanz filings and corporate-tax returns. Not worth the overhead for solo freelancers; useful from ~€80k+ profit if structuring for asset protection or future growth.

Holiday, sick leave, and dismissal protection

Statutory minimum holiday is 24 working days for a 6-day week (20 for a 5-day week). Most contracts offer 28–30 days — anything below 25 in an office job is unusually low. Public holidays vary by Bundesland (10 in Berlin, 13 in Bavaria, etc.) and are on top of the contractual holiday.

Sick pay (Lohnfortzahlung): the employer pays 100% of salary for the first 6 weeks of illness, evidenced by a Krankschreibung from a doctor (now usually electronic). After 6 weeks, the public Krankenkasse pays Krankengeld at ~70% of net up to 78 weeks for the same illness in 3 years.

Dismissal protection: after 6 months at an employer with 10+ workers, the Kündigungsschutzgesetz kicks in — you can only be fired for one of three legal reasons (personal, behavioural, business-related), with notice periods that scale with tenure (1 month minimum, up to 7 months after 20 years). Settlements (Aufhebungsvertrag) are common and typical payouts are 0.5–1 month of salary per year of service.
