Taxes in Germany: Tax ID, Classes, and Filing Basics

Deductions from your gross salary are significant, but a common misconception is that Germany is a global outlier for high taxation. For employees, taxes are withheld automatically through payroll. Understanding tax classes and filing returns can still save you money.

German income tax is progressive: the more you earn, the higher percentage you pay. Rates range from 0% (the basic tax-free allowance, Grundfreibetrag, was €12,096 in 2025 and €12,348 in 2026) up to 45% for very high incomes. On top of income tax, you pay social contributions for health, pension, unemployment, and long-term care insurance.

Your employer withholds taxes and sends them to the tax office (Finanzamt). You receive net salary after all deductions. Self-employed people must handle taxes themselves. For net vs gross budgeting, see Cost of Living in Germany. For address registration and your Steuer-ID, see Registering Your Address in Germany.

How Germany compares internationally

Western European baseline. If you are a single professional, your net take-home pay in Germany is roughly similar to what you would keep in neighboring countries. Data consistently shows that single earners in Belgium, France, and Austria face a comparable or even heavier overall tax and social security burden than those in Germany.

Married couples and families. Joint taxation (Ehegattensplitting) and benefits such as Kindergeld often improve net take-home pay compared with single earners. In international comparisons, married couples with children often keep more net income in Germany than in France, Finland, or Belgium.

Social security vs income tax. Unlike systems funded mainly through income tax, such as Denmark, a large share of German deductions goes into social security. Your paycheck helps fund your own health insurance, sick leave, and statutory pension entitlements, not only general government spending. For health insurance details, see Health Insurance in Germany. For statutory pension and retirement planning, see Preparing for Retirement in Germany.

Tax classes (Steuerklasse)

Your tax class determines how much is withheld from your salary each month.

• Class I: Default for most single, divorced, or widowed people
• Class II: Single parents, with lower tax and an extra allowance
• Class III / IV / V: For married couples. Class IV is standard when both spouses earn similar amounts. Class III for the higher earner plus Class V for the lower earner usually means less monthly withholding overall
• Class VI: Second jobs, with the highest withholding

A common strategy for married couples is III/V, which connects to Ehegattensplitting at year-end. You must file a tax return if you use that combination. If you worked only part of the year, filing often produces a refund because withholding assumed a full year of income. See Leaving Germany if you depart mid-year.

Tax class rules are complicated and depend on your household, income, and plans. Before you change classes, check what fits your exact situation and future plans. A Steuerberater (tax advisor) can help you work through the options. Some constellations look straightforward on paper but still lead to an unpleasant surprise at filing time.

What gets deducted from your salary

Several deductions come off your gross salary:

• Lohnsteuer (wage tax): roughly 14% to 42% for most incomes, with a 45% top rate (Reichensteuer) for very high earners
• Solidarity surcharge (Solidaritätszuschlag): 5.5% of your tax for higher earners
• Church tax (Kirchensteuer): 8% to 9% of your tax if you are a registered church member

Social contributions (employee share, approximate):

• Health insurance: about 8.75% of gross (general rate 7.3% plus roughly half of the average Zusatzbeitrag)
• Pension insurance: about 9.3%
• Unemployment insurance: about 1.3%
• Long-term care insurance: about 1.7% to 2.3%, depending on whether you have children

Your employer usually pays matching amounts for most social contributions. In total, expect about 35% to 45% of gross salary to be deducted.

Filing a tax return (Steuererklärung)

Filing is mandatory for self-employed people, freelancers, married couples using Class III/V, people with multiple income sources, and those receiving certain tax-free benefits.

For most other employees it is optional, but often worthwhile. The average refund is around €1,000. Filing is especially useful if you have high commuting costs, work-related expenses, or only worked part of the year.

Deadlines (typical):

• End of July the following year if you file yourself
• End of February the year after that if you use a tax advisor (Steuerberater) (confirm the current year’s deadline, which can shift)
• Voluntary returns can often be filed up to 4 years retroactively

Common deductions:

• Pendlerpauschale (commuting allowance): €0.38 per kilometer one way for the full commute (usually capped at €4,500 per year unless you use a car)
• Work equipment such as computers, tools, and professional books
• Home office allowance: €6 per day, up to 210 days (max €1,260 per year)
• Occupation-specific work clothing and job-related training
• Job-related moving expenses, liability and professional insurance
• Donations to registered charities
• 80% of childcare costs, up to €4,800 per child

Everyone automatically receives the Werbungskostenpauschale of €1,230. Itemize only if your actual work-related deductions exceed that amount.

Tax identification numbers

Germany uses three different tax numbers. Mixing them up is a common newcomer mistake. Each has a different purpose, issuer, and lifetime.

Steuer-ID (personal tax ID)

Your permanent, personal tax identification number: 11 digits, assigned to everyone registered in Germany, including children.

• Issued automatically by mail within a few weeks of your first address registration (Anmeldung)
• Never changes, even if you move cities, marry, rename, leave Germany, or return years later
• Needed for employers (payroll tax), banks (interest reporting), child benefit applications, and many official forms

If you lose the letter, request it again from the Bundeszentralamt für Steuern (BZSt). Delivery usually takes about two to four weeks.

Steuernummer (tax office number)

Assigned by your local Finanzamt for income tax returns and domestic tax matters. The format varies by region (for example, 133/8150/8159 in Berlin looks different from a Bavarian number).

• Can change when you move to a different tax district because a new Finanzamt takes your file
• Often assigned when you file your first tax return or register self-employment, which can take several weeks
• Employees usually only need the Steuer-ID for payroll. The Finanzamt assigns a Steuernummer when you file a return
• Self-employed people and freelancers need a Steuernummer from day one. It goes on domestic invoices

Obtain it via the tax registration form (Fragebogen zur steuerlichen Erfassung) through ELSTER. See Starting as a Freelancer in Germany and Self-Employment in Germany 101.

USt-ID (EU VAT ID)

The Umsatzsteuer-Identifikationsnummer is for cross-border EU business only. Format: DE plus 9 digits (for example DE123456789).

• Issued by the BZSt on application, not automatically
• Needed if you charge VAT and trade goods or services with other EU countries
• Show it on invoices to EU business clients
• Most Kleinunternehmer (small business VAT exemption) do not need one because they do not charge VAT. See Self-Employment in Germany 101

When you need which number

How to get each

• Steuer-ID: wait after Anmeldung, or request online from the BZSt if the letter never arrives
• Steuernummer: file your first return or register self-employment via ELSTER / local Finanzamt
• USt-ID: apply at the BZSt online or through ELSTER. Processing takes from a few days to a few weeks

Self-employed taxes

If you work for yourself, you handle quarterly estimated income tax, VAT where applicable, and full social insurance without an employer share. Keep detailed income and expense records. A Steuerberater (tax advisor) is worth hiring from the start. See Starting as a Freelancer in Germany, Starting a Business in Germany, and Freelance Visa for Germany.

Related pitfalls

Common mistakes to avoid

Short warnings linked to this guide. Each item highlights a costly or legal slip newcomers often make.

1. Misunderstanding Tax Class III/V

   Medium

   Assuming Class III/V lowers total annual tax. It only shifts monthly liquidity and often triggers mandatory back-payments upon filing.

2. Ignoring mandatory tax filing requirements

   Medium

   Required for Class III/V, multiple jobs, or wage replacements >€410. Missing the deadline triggers a minimum late-filing surcharge of €25/month.

3. Forgoing voluntary tax returns

   Medium

   Failing to file within the 4-year limit results in the loss of average tax refunds exceeding €1,000 per year.

4. Concealing global income

   High

   Failing to declare foreign rental or dividend income. International CRS data sharing triggers retroactive taxation and evasion fines.

5. Paying tradespeople in cash

   Medium

   To claim the 20% (up to €1,200) household-services tax deduction, payments must be processed via bank transfer. Cash invoices are categorically rejected by the tax office.

6. Forfeiting the home office equipment deduction

   Medium

   Deductibility of office furniture and equipment does not depend solely on being in a separate home office; movable work equipment can often still be deductible if used predominantly for business, while special rules apply to the home-office room itself.

7. Failing to claim the commuting allowance

   Medium

   The commuter allowance applies regardless of transport method, usually €0.30 per km for the first 20 km and €0.38 from the 21st km in 2026, with special caps for non-car cases unless actual public-transport costs are higher.

8. Missing the relocation lump sum

   Medium

   For work-related moves, compare actual deductible costs with any available moving lump sums or employer reimbursement rules; the flat-rate approach can reduce paperwork but is not always better.

9. Failing to declare foreign bank accounts

   High

   Germany does not tax the mere holding of foreign bank accounts, but foreign interest and other taxable income must still be declared; international information exchange such as CRS increases the risk that undeclared income is discovered.

10. Assuming the 183-day rule prevents all tax

    High

    The 183-day rule in tax treaties is not a universal exemption; source taxation can still apply, for example if the employer has a German permanent establishment bearing the remuneration or other treaty conditions are not met.

11. Missing the tax deadline via standard submission

    Medium

    Using a tax adviser can often extend the filing deadline compared with self-filing, but it does not automatically eliminate late-filing penalties if deadlines are still missed.

12. Keeping stocks on non-German brokers

    High

    Using a foreign broker is not inherently wrong, but it usually shifts tax reporting and record-keeping onto the taxpayer because German withholding and automation may not happen.
