Avoid common mistakes

Mistake 1: No separation private/business

Open a separate business account from the start. This saves a lot of trouble with the tax office later.

Mistake 2: Underestimate taxes

Set aside at least 30-40% of your income for taxes. Income tax and VAT will come for sure.

Mistake 3: No reserves

The first months can be difficult. Plan reserves for at least 6 months.

Mistake 4: Prices too low

Calculate your hourly rate carefully. As a self-employed person, you have to finance health insurance, pension, vacation and downtime yourself.

Mistake 5: No written agreements

Record all agreements in writing - quotes, order confirmations, contracts. This protects you in disputes.

Conclusion

Self-employment requires some bureaucratic steps - but with the right checklist, you keep track. Take the time to set everything up properly. A clean start saves a lot of trouble and costs later.

With Clever Invoice, you're professionally set up from the first invoice: All mandatory information is automatically correct, e-invoices are possible, and your accounting is clear from the start.

Frequently asked questions

Do I need a business registration as a freelancer?

No, freelancers (e.g., doctors, lawyers, designers, journalists, consultants) register directly with the tax office and don't need a trade license. Whether you count as a freelancer depends on your activity - in doubt, the tax office clarifies this.

How much startup capital do I need for self-employment?

This depends heavily on your industry. As a freelancer in the service sector, you often get by with a few hundred euros. Basically, you should have reserves for 3-6 months of living expenses, plus budget for basic equipment and initial marketing measures.

When must I register with the tax office?

Within 4 weeks after starting your activity, you must submit the "Tax registration questionnaire" to the tax office. This can be done online via ELSTER. You'll then receive your tax number, which you need for invoices.

Can I use the small business regulation?

Yes, if your sales in the previous year were under 25,000 € and will probably be under 100,000 € in the current year (new limits from 2025). As a small business owner, you don't show VAT - but also can't deduct input tax.

Do I need a tax advisor?

Not legally mandatory, but highly recommended. A tax advisor knows all funding opportunities and deduction possibilities, handles communication with the tax office and gives you security. The costs are often tax-deductible and pay for themselves through saved taxes.
