Quasi-resident tax status in Geneva: the 90% test and subsequent assessment

What quasi-resident status means

You remain resident abroad. This tax status does not make you a Swiss resident or change your immigration permit. It can open access to a subsequent ordinary assessment, called taxation ordinaire ultérieure (TOU) in Geneva.

The administration recalculates tax from a return under ordinary rules and credits tax already withheld. Payroll withholding and the final assessment are not two separate taxes to add together.

This article primarily concerns non-resident employees taxed in Geneva, particularly French residents. Working in Switzerland alone does not determine where salary is taxable: the canton, treaty and working arrangements matter.

Calculate the 90% test

Gross income taxable in Switzerland ÷ worldwide gross income × 100. The general threshold is at least 90%. For spouses living together, include both spouses’ worldwide income.

Do not divide only your Swiss salary by the couple’s salaries, or directly use the French revenu fiscal de référence. Inventory salaries and bonuses, self-employment, pensions and replacement income, maintenance received, property income, interest and dividends. A spouse without salary may still have investment income.

Payment from Switzerland does not necessarily make income taxable there. Swiss bank interest received by a French resident does not become Swiss-taxable solely because the bank is Swiss. International civil servants’ income also requires examination despite possible exemption arrangements.

These examples assume all relevant income has been included. Use Geneva’s official quasi-resident calculator for the tax year. They illustrate arithmetic, not approval of an individual application.

Owner-occupied housing

A home you occupy can produce a taxable imputed rental value even without rent receipts. Examine it under Swiss rules rather than omitting it because it is not rental income on the French return. The location and recognised rental value matter; do not apply an unverified online percentage.

Distinguish gross income used for eligibility from amounts after deductions in the assessment. A spouse’s changed activity, new rental income or a changed allocation of salary can alter the result, so reassess every year.

Deductions to examine

A TOU can allow examination of pillar 3a contributions, occupational pension buy-ins, childcare, certain maintenance payments and training costs. Eligibility conditions and annual limits still apply. Quasi-resident status does not make every expense deductible.

For professional costs, use actual working days and supported expenses. Commuting, meals and remote-working days are not automatically treated alike. Avoid claiming costs reimbursed by the employer.

For children, document care arrangements, maintenance and how costs are divided. For retirement savings, check the right to contribute, payments and the year’s pillar 3a contribution limit. A payment certificate or second-pillar buy-in does not by itself establish that a TOU will save tax.

Foreign income and assets

The return must describe the relevant worldwide position, including property, bank accounts, securities, debts and related income, to permit proper allocation. Separate what Switzerland may tax from what determines the applicable rate. Disclosure alone does not settle taxing rights.

French real estate is generally allocated to France. Its income or imputed rent can nevertheless influence the Swiss rate. Quasi-residence does not make all worldwide wealth fully taxable in Geneva. Swiss real estate or self-employment requires particular examination.

Debts, interest and deductions may also need allocation. A reliable comparison does not subtract every foreign cost from Geneva salary. The Geneva tax shield has its own scope and should not be assumed to follow automatically from quasi-resident status.

Compare both complete tax calculations

A deduction reduces taxable income; it is not repaid franc for franc. Tax-at-source scales already include standard deductions. Compare complete tax amounts rather than adding up hoped-for deductions.

1. Reconstruct withholding and check salary and family information.
2. Test quasi-residence using worldwide income.
3. Estimate ordinary tax with relevant income, assets, allocations and deductions.
4. Compare the final liability with tax already withheld and include preparation fees.

Use scenarios where important information is missing. A small estimated saving is not conclusive if rental value, a spouse’s income or a deduction remains uncertain.

The result may be a refund or additional tax. In Geneva, a submitted request cannot be withdrawn simply because the outcome is unfavourable. Do not submit it as a trial calculation.

Karpeo offers an initial 30-minute scoping consultation at CHF 89 including VAT. It identifies the questions and records needed; it does not include a full tax study or preparation of the return. For help preparing your return, see our Geneva tax return service. Contact Karpeo to arrange the appropriate support.

The application deadline and supporting file

The request concerns the preceding year and must be submitted by 31 March, a non-extendable deadline. The ordinary deadline for 2025 income was 31 March 2026 and has passed. For 2026 income, prepare for 31 March 2027.

This is the request deadline, not necessarily the deadline for completing the entire tax return. An extension to file a return does not replace the initial request. Use Geneva’s e-démarches tax account or the official signed paper DRIS/TOU form. DRIS means demande de rectification de l’impôt à la source, a request to correct withholding tax.

Do not miss the request deadline while waiting for a supporting document. Keep submission evidence; an informal message is not a substitute for the required channel.

• Salary certificates and withholding statements from every employer.
• Spouse income and other worldwide-income evidence.
• Bank, securities, debt and interest statements.
• Property purchase, income, occupation and rental-value records.
• Pension certificates and evidence for deductions.
• Relevant family, care and maintenance documents.

After the request, complete the return sent by the administration by its stated deadline, with the quasi-residence form and evidence. Arrange reliable postal notification or electronic correspondence. Review the final assessment, especially deductions, international allocation and credited withholding. The tax-return document checklist helps organise the file.

Annual requests for non-residents

A non-resident’s request for one year does not cover following years. Recheck eligibility and apply again when appropriate. This does not allow withdrawal of a request already filed for the year under assessment.

Swiss residents follow different continuation rules. Saying that quasi-resident status requires a Swiss return for life confuses the two situations. A TOU may also be initiated by the authority in certain non-resident cases, notably involving Geneva property or self-employment; distinguish this from the annual option discussed here.
