FAQ
What our clients ask most often.
How much does it cost to have my tax return done?
Our prices are starting prices, because every tax return is individual: from CHF 59 for individuals, from CHF 100 for families and married couples, and from CHF 60 per hour for the self-employed. If any extra work is needed, we tell you before we start — not with the invoice.
How long does it take until my tax return is ready?
Once your documents are complete, you will usually receive your completed tax return for review within three working days. In the peak season of February and March it can take a few days longer. Nothing is filed until you have approved it.
What is the tax return deadline in the Canton of Zurich?
31 March of the year following the tax period. If you cannot meet this deadline, request a filing extension beforehand — a first request submitted in time to your municipal tax office is deemed approved even without a reply, up to 30 November at the latest. We submit the request for you.
Which documents do I need?
The essentials: your last tax return and tax assessment notice, all salary certificates, bank and custody account statements as at 31 December, your Pillar 3a certificate, your health insurance premium certificate and receipts for medical costs, further training and donations. You will find the complete checklist under «Process».
Do I have to come in person?
No. You can submit everything online using our form or send your documents by post to Archplatz 2 in Winterthur. A personal appointment is possible if you prefer to talk face to face — Saturdays too, by arrangement.
What happens to my data?
Your documents are used solely to prepare your tax return, processed on servers in Switzerland or the EU, and archived after completion in line with the statutory retention periods. We do not pass any data on to third parties.
Do you also handle objections to a tax assessment?
Yes. We check the tax assessment notice against the return that was filed and, if necessary, lodge a reasoned objection within the 30-day deadline. This is charged by time, from CHF 60 per hour.
Do you also work for people outside Winterthur?
Yes. We look after taxpayers throughout the Canton of Zurich and beyond. As returns are filed electronically, where you live makes no difference to working with us.
Can we help?
Your tax return, done in three days.
Book an appointment — you don’t need any documents yet. We clarify your situation in a conversation, check every deduction and file electronically. All you do is approve.
