Key Business Terms for Entrepreneurs in Germany 2026

The moment you go self-employed in Germany, you hit a wall of jargon: Gewerbesteuer, Vorsteuer, Fragebogen zur steuerlichen Erfassung, USt-IdNr. German bureaucracy speaks its own language – and nobody explains it to you for free.

The catch: these words aren't theory. Behind each one sits a duty, a deadline, or a sum of money. Miss what "Vorsteuer" means and you give away cash. Misread your "Steuerbescheid" and you overpay or blow your chance to object.

This guide walks you through the terms you actually need as a founder in 2026 – grouped by theme, with current figures and no civil-servant German. Not a list to memorize, but a reference for everyday life.

The main types of tax

• Steuer (tax): The mandatory payment to the state. As a self-employed person, three matter most: income tax, VAT, and (for trades) trade tax.
• Einkommensteuer (income tax): Tax on your profit – revenue minus business expenses. In 2026 the first slice of income stays tax-free: the basic allowance (Grundfreibetrag) sits at roughly €12,348.
• Umsatzsteuer (USt) / Mehrwertsteuer (MwSt) – VAT: The tax you add to invoices (usually 19%, reduced 7%) and pass on to the tax office. For you it's a pass-through item, not profit.
• Vorsteuer (input VAT): The VAT you pay on purchases. You can reclaim it from the tax office and offset it against the VAT you collected. See the input VAT deduction guide.
• Gewerbesteuer (trade tax): A municipal tax for traders. Freelancers don't pay it. An allowance of €24,500 shields most small trades.

Your status: freelancer or trade

• Gewerbe (trade): A commercial activity (retail, crafts, many online businesses). It must be registered with the trade office.
• Freiberufler (freelancer): Someone in a "catalogue profession" (doctor, lawyer, designer, developer, etc.). The upside: no trade registration, no trade tax. Check whether you qualify in Freelancer or trader?.
• Steuernummer & USt-IdNr.: The tax number arrives after you register; the VAT ID is the extra one you need for EU clients. Full breakdown in tax number vs. VAT ID.

Registering with the tax office

• Finanzamt (tax office): The authority that manages your taxes. It sets your status and receives your filings.
• Fragebogen zur steuerlichen Erfassung (tax registration questionnaire): Your first mandatory step after starting up. Filed via ELSTER, it decides things like small-business status and prepayments.
• ELSTER: The tax office's free online portal for all tax filings. Mandatory for electronic submission.
• Steuererklärung (tax return): Your annual reckoning with the tax office – see the self-employed tax guide.

Invoices, small business, and e-invoicing

• Rechnung (invoice): Your proof of payment – with legally required details. Miss one and your client's input VAT deduction can collapse.
• Kleinunternehmerregelung (small-business rule, §19 UStG): If your turnover was under €25,000 last year and stays under €100,000 this year, you can skip charging VAT. Pros and cons in the Kleinunternehmer rule explained.
• E-Rechnung (e-invoice): Since 2025, B2B businesses must be able to receive structured electronic invoices – small businesses included. The obligation to send phases in through 2028. What Norman handles is on the e-invoicing page.

Insurance and social security

• Sozialversicherung (social insurance): The umbrella term for health, pension, unemployment, and long-term-care insurance.
• Krankenversicherung (health insurance): Mandatory for the self-employed – statutory or private. Often the biggest fixed cost a founder carries.
• KSK (Künstlersozialkasse): For creatives and publicists. It covers roughly half your social contributions – like an employer's share.

Mail from the tax office: assessment and reminder

• Steuerbescheid (tax assessment): The tax office's official answer. Check it – you can object within one month if it's wrong.
• Mahnung (reminder): A payment reminder – from the tax office or a client. Ignoring it gets expensive.
