Good to know
When do I have to file my tax return in the canton of Zurich?
Usually by 31 March of the following year. An extension is possible. If we prepare your tax return, we also take care of the deadline.
I am taxed at source – can I still file a tax return?
Yes. People taxed at source can apply for a subsequent ordinary assessment by 31 March of the following year; from a gross income of CHF 120,000 it is mandatory. It is often worthwhile, for example with pillar 3a contributions or pension fund buy-ins. Important: the application also applies to the following years.
Which documents do I need for my tax return?
Among others, your salary certificate, bank and custody account statements as of 31 December, pillar 3a and pension fund certificates, interest on debts, and medical and training costs. Our tax checklist guides you step by step.
Salary or dividend – which is better for me as an owner?
It depends on profit, social security, the pension fund and the tax burden of the company and of you personally. We calculate both options and recommend the right solution.
