German tax, made understandable.
Solobooks is software for the income tax return and bookkeeping in Germany. We make German tax manageable for self-employed people and employees, in English and in German.
Who Solobooks is for
- Freelancers and self-employed people who do their own bookkeeping and want their income-surplus statement (Einnahmenüberschussrechnung, EÜR) without the detours.
- Employees who file their own income tax return (Einkommensteuererklärung), including those with self-employed work on the side.
- People who have moved to Germany and would rather work in English. The app and our support are available in English and German.
Why Solobooks exists
If you are self-employed in Germany, or you file your own return, you face forms, technical terms and deadlines, usually in German only.
Solobooks is here to make that easier. A few principles guide how we build it:
- Plain language, not form language. The assistant asks clear questions and fills in the forms for you.
- You see the number before you decide. Your estimated refund is worked out while you fill things in.
- Honest about scope. Our assistant does not cover rental income or pensions. We tell you up front, not two hours in.
- German tax, in English. Our English explanations keep the German terms alongside, so you recognise them on letters from the tax office (Finanzamt).
What we offer
Income tax return: a guided assistant for the whole return, including the EÜR and Anlage S for self-employed income and joint returns for married couples. We submit the finished return to ELSTER, the tax authorities' online filing system, and the submission receipt is then stored in your account.
Bookkeeping: invoices with VAT, bank import, the EÜR, VAT returns (Umsatzsteuer-Voranmeldung) filed directly to ELSTER, and DATEV export for your tax adviser.
You can see what each costs on our pricing page.
How we work
- Servers in Germany. Our backend and database run on servers operated by Hetzner Online GmbH in Germany.
- GDPR-compliant. Our privacy policy sets out which data we process and why.
- Straight to the tax office. We submit returns electronically through the official ELSTER interface.
- Not a tax advisory service. We prepare your information and submit it to ELSTER. When the answer depends on your individual situation, a tax adviser (Steuerberater) is the right person to ask.
Who is behind Solobooks
