Filing a tax return in Switzerland is an annual obligation for every resident taxpayer. The Swiss tax system is complex: it combines a direct federal tax (IFD) with cantonal and communal taxes that vary considerably from one location to another. Each canton applies its own tax rates, deductions, and deadlines.

At MyTaxAdvisor, our certified tax experts handle your entire tax return. We methodically analyze your personal and professional situation to identify all deductions you are entitled to: pillar 3a contributions (up to CHF 7,258 in 2025), LPP buybacks, actual professional expenses, health insurance premiums, mortgage interest, continuing education costs, and many more.

Our process is fully digital: you submit your documents via our secure platform, our experts prepare your return while maximizing your deductions, and you approve it before submission. Each return is reviewed by a second expert to ensure accuracy and maximum optimization.

Whether you are an employee with a straightforward situation or self-employed with multiple income sources, we tailor our approach to your profile. Our fees are tax-deductible as private wealth administration expenses, which reduces the effective cost of our services.
