Terms and conditions
Last updated: November 2026. This is a translation; the German version prevails.
1. Scope
These terms apply to all orders for preparing tax returns for private individuals placed via steuern2do.ch, a brand of dador.ch GmbH, Beckenriederstrasse 42, 6374 Buochs («we»).
2. Request and contract
Requests via the website are free and non-binding. A contract is formed when we confirm the fixed price in writing (e.g. by email) and you then send us your documents or confirm the order.
3. Services
The fixed price includes preparing the tax return for the agreed tax year, checking all deductions possible for your situation, requesting a deadline extension, declaring securities up to 10 positions, filing electronically with the tax office and checking the final assessment. An objection against the assessment is included if it deviates from the filed return. Further services (e.g. appeals, supplementary or penalty tax proceedings, tax planning, bookkeeping) are provided only on a separate quote.
4. Prices
The fixed prices published on the website apply, in Swiss francs incl. VAT. If more work is needed than usual for the chosen package (e.g. self-employment, arrival or departure year, income or assets abroad, withholding tax), we quote the extra work as a fixed price before we start. We never charge extra without your consent.
5. Your cooperation
You provide complete and truthful documents and information and tell us about all tax-relevant circumstances. You check the finished return before filing. You remain responsible towards the tax authority for the accuracy and completeness of your information.
6. Payment and filing
Once finished, you receive the return for review together with the invoice, payable within 10 days. We file the return as soon as your payment has arrived. Late payment delays filing accordingly.
7. Deadlines
We request a deadline extension as soon as we have your documents. To meet a deadline we need complete documents at least 3 weeks before it expires. We accept no liability for consequences of late or incomplete documents or late payment.
8. Liability
We are liable for damage caused intentionally or by gross negligence. For slight negligence, liability is limited – as far as legally permitted – to the fee for the order concerned. The tax owed is not a damage. No liability for consequences of incorrect, incomplete or late information or documents.
9. Confidentiality and data protection
We treat your documents confidentially. Data processing is governed by our privacy policy.
10. Document upload
Only upload documents you are entitled to share. Uploading alone does not create an order. Documents without an order within 90 days are deleted. We aim for high availability but cannot guarantee it; documents can always be sent by email.
11. Termination
Either party may end the order at any time. Work done until then is charged pro rata, at most up to the agreed fixed price.
12. Law and jurisdiction
Swiss law applies. Place of jurisdiction is the registered office of dador.ch GmbH, subject to mandatory places of jurisdiction, in particular for consumers.
