Tax Advisory in Geneva

Structure your wealth tax-efficiently and stay fully compliant across all three levels of Swiss taxation.

Switzerland’s federal system means tax rules differ across the 26 cantons, and each canton and commune sets its own rates. Our advisers help private clients and foreign residents in Geneva understand their obligations, claim every deduction they are entitled to, and structure their affairs efficiently under Swiss and international tax law.

In practice we prepare and file your annual tax return, review prior assessments for missed deductions, and advise ahead of major decisions — a property purchase, a bonus, a pension withdrawal or a move between cantons — so the tax consequences are known before you act, not after.

Frequently asked questions

Do foreign residents in Switzerland need to file a tax return?

Those taxed at source may be able — or required — to file an ordinary return to claim deductions the withholding rate does not capture, such as pillar 3a contributions and professional expenses. It depends on income level and canton.

Can changing canton reduce my tax bill?

Potentially, and significantly — the income and wealth tax burden varies widely between cantons. A properly executed change of domicile is entirely legal and can generate substantial savings.

Do you prepare and file the tax return for me?

Yes. We prepare your federal, cantonal and communal return, handle the filing, and deal with the tax authority’s queries on your behalf.

Do you advise the self-employed and business owners?

Yes. We advise the self-employed, partnerships and business owners on their private and business tax position, pension contributions and efficient structuring.
