ELSTER for freelancers: file your tax returns directly from KontoVexa
Self-employed people in Germany must file their tax returns electronically. Instead of typing every figure into Mein ELSTER by hand, you send them straight from your bookkeeping with KontoVexa.
What is ELSTER?
ELSTER (Elektronische Steuererklärung, electronic tax return) is the online portal of the German tax administration. Electronic filing is mandatory for the self-employed: the advance VAT return (Umsatzsteuer-Voranmeldung), annual VAT return (Umsatzsteuer-Jahreserklärung), EC sales list (Zusammenfassende Meldung), Anlage EÜR, trade tax and income tax returns all go to the tax office via ELSTER.
ELSTER account and certificate
To file, you need a user account with Mein ELSTER. When you register, you receive activation data by post and then download your certificate file (.pfx), which you protect with your password (PIN). Allow about two weeks for the registration.
Which returns can you file with KontoVexa?
On the Business and Pro plans you file these returns directly from KontoVexa:
- Advance VAT return (Umsatzsteuer-Voranmeldung, UStVA), monthly or quarterly.
- Annual VAT return (Umsatzsteuer-Jahreserklärung).
- EC sales list (Zusammenfassende Meldung, ZM) for services to businesses in the EU.
- Anlage EÜR with the asset register (AVEÜR).
- Trade tax return (Gewerbesteuererklärung).
How filing works
KontoVexa fills in the fields (Kennzahlen) from your bookings and shows each field with its original name from the ELSTER form. Before sending, KontoVexa checks the data with ERiC, the official interface of the tax administration. You send with your ELSTER certificate and PIN, and the transmission log is stored with the return.
You still file the main income tax form (Mantelbogen) in Mein ELSTER or through your tax advisor; the Anlage EÜR comes ready-made from KontoVexa.
Frequently asked questions
Is ELSTER free?
Yes, Mein ELSTER is free. KontoVexa saves you the typing: the figures come straight from your invoices and receipts.

Yes. You upload your certificate file to KontoVexa once; it is stored encrypted, and you enter your PIN for each submission.
Do I get a confirmation from the tax office (Finanzamt)?
