Details and tips
👨🏻‍💻
Max recommends:

My bookkeeping is a three-column table: date, invoice, payment. That suffices for the EUeR; one hour a month — no May panic. The business account was separate from day one.

Lea recommends:

Every invoice needs the mandatory § 19 UStG line. Forgot it and showed VAT? Correct immediately by letter: an uncorrected invoice obliges you to pay the stated tax.


FREQUENTLY ASKED QUESTIONS

A client in another EU country — does anything change?

Yes, EU services fall under reverse charge: the invoice carries the recipient-liability clause, and you need a VAT ID despite the status. Request it from the tax office in advance.

Can I reclaim VAT on my laptop and software?

No — that is the price of the status: you charge no VAT but deduct no input VAT either. With many purchases or B2B clients, standard taxation often pays from day one.

I put 19 percent VAT out of habit — now what?

VAT shown on an invoice is owed to the tax office even without the right to charge it (§ 14c UStG). The cure: a corrected invoice with the client — do it immediately.

Do I need software or an accountant?

Formally a spreadsheet and a folder suffice. Practically, software at ~€10–20/month automates invoices with the right line, the EÜR and the limit alert.
