Steuerkomplize explains the fixed prices

What does it cost? Ask the Komplize.

One fixed price per tax return. You know it before starting and pay only once the completed PDF reaches you.

Your Steuerkomplizeonline
These deductions are often forgotten. I won't forget them.

Work expenses

Commuting by public transport or car, meals, further education and home office costs.

Retirement provision

Pillar 3a, pension fund purchases and life insurance. Potential savings of hundreds of francs each year.

Health

Health insurance premiums, dentist, glasses, hearing aids, cost sharing and premium subsidies.

Family

Child deductions, childcare, education expenses, maintenance payments and supported persons.

Home ownership

Maintenance, mortgage interest, energy improvements and management costs.

Donations & debt

Donations, political party contributions and interest on loans and credit cards.

We don't teach tax theory. We complete your tax return and then explain in three sentences where you could save next year.

For years, we've prepared tax returns for family, friends and customers in Zurich, Thurgau, Schaffhausen and St. Gallen, using each canton's official tax software.

Access your case through your personal link. See the documents received, answer questions and keep track of next steps. You decide separately on longer storage for the optional annual folder.

Steuerkomplize answers frequently asked questions
Do I need all my documents straight away?
No. Start with what you have. Your checklist shows what's missing so you can upload it later. We'll remind you after a few days.
How secure is my data?
Encrypted on servers in the EU and accessible only through your personal link.
When do I pay?
Only once your tax return is ready. You receive an invoice with a payment link (card or TWINT) or a QR bill.
How long does it take?
Usually 3 to 7 days once all documents are in. It can take longer towards the end of March, so start early. In a hurry? Express preparation within 72 hours costs + CHF 100.-
Do you also submit the return?
You receive the completed PDF and sign it yourself. Submit it by post or through your canton's online portal. We explain exactly how.
Do I need a deadline extension?
If you start after mid-March, we'll take care of it. It's included in the price.
I live in another canton.
Start the form anyway. We review other cantons individually and get back to you.
What happens to my data afterwards?
Regular documents are deleted 90 days after completion. You can download them beforehand. Your optional annual folder follows the date you separately agreed to.
