Cantonal knowledge

Tax return in the Canton of Geneva – what you should know

Geneva calculates differently from German-speaking Switzerland: with additional centimes instead of tax multipliers, a tax rebate dating from 1999 and some of the most generous – and strictest – deductions in Switzerland.

Centimes additionnels instead of a tax multiplier

On the cantonal basic tax (impôt de base), the canton adds 47.5 per cent in additional centimes (centimes additionnels), reduced by a statutory tax rebate of 12 per cent, plus 1 per cent for home care. In addition, each of the 45 communes levies its own centimes additionnels on the same basic tax.

The range among the communes is wide: in 2025 it runs from 25 (Genthod, Cologny) to 51 additional centimes (Avully, Chancy); the City of Geneva is at 45.49. On top of this comes a taxe personnelle of CHF 25 per adult. The decisive factor is the commune of residence at the end of the year.

GeTax and e-démarches

The return is completed with GeTax, the free software of the Geneva tax administration, or directly online in the e-démarches portal – with the previous year's data carried over. The large majority of Geneva taxpayers no longer receive a paper return, only the access codes.

The portal is an option for anyone who wants to complete the return themselves. If you want to be sure that every item is recorded correctly and completely, we take care of it for you: we record your details, discuss the draft with you and prepare the filing.

Typical mistakes that cost Geneva taxpayers money

In practice, we see the same points time and again: the generous health insurance deduction is not used in full, while too much is entered for the strictly capped travel expenses deduction (CHF 534). The deadline extension is applied for too late and costs unnecessarily much. And people taxed at source miss the forfeiture deadline of 31 March for the application for a subsequent ordinary assessment.

The high deduction for family dependants (CHF 13'660 per full dependant) and third-party childcare costs of up to CHF 26'320 per child also need to be recorded correctly. A specialist checks each item individually before the return is filed.

Tax deductions in the Canton of Geneva – making use of every option

Anyone who knows all the permissible deductions and claims them correctly reduces their tax burden noticeably. We check every deduction item systematically for your situation. The following maximum amounts apply to tax year 2025; the official information of the AFC is decisive.

  1. 01

    Health insurance premiums & insurance

    Geneva's most generous deduction: health insurance premiums are deductible up to twice the cantonal average premium – in 2025 up to CHF 17'122 per adult (aged 26 and over), CHF 12'842 for 19- to 25-year-olds and CHF 3'965 per child. On top of this comes the deduction for insurance premiums and savings interest.

  2. 02

    Family dependants & third-party childcare

    The deduction for family dependants (charge de famille) is CHF 13'660 per full dependant or CHF 6'830 per half dependant. In addition, documented third-party childcare costs of up to CHF 26'320 per child under 14 (tax year 2025).

  3. 03

    Pillar 3a & pension provision

    Contributions to restricted pension provision are deductible up to CHF 7'258 (tax year 2025, employees with a pension fund); pension fund buy-ins come on top. We assign the certificates to the correct item and check whether the permissible amount has been used in full.

  4. 04

    Professional expenses & commuter deduction

    When it comes to the travel expenses deduction, Geneva is strict: at cantonal level, a maximum of CHF 534 per year for all means of transport (federal: CHF 3'300). In addition, meals away from home at CHF 15 per working day or a maximum of CHF 3'200 per year, and the lump-sum deduction for other professional expenses.

  5. 05

    Continuing education costs

    Job-related education and continuing education: at cantonal level up to CHF 12'756 per person and year (tax year 2025). This includes course fees, teaching materials, examination fees and travel costs to the course venue.

  6. 06

    Donations & charitable contributions

    Voluntary contributions to tax-exempt charitable institutions domiciled in Switzerland as well as contributions to political parties, in each case within the applicable limits.

There are also further items such as debt interest, maintenance payments, property costs or asset management costs. We clarify which deductions can be substantiated in your situation before processing – free of charge and without obligation.

Withholding tax

Withholding tax in the Canton of Geneva

Hardly any canton has as many employees taxed at source and cross-border commuters as Geneva. This makes it all the more important to know when a subsequent ordinary assessment is worthwhile – and when it is compulsory.

01

Who is subject to withholding tax?

In principle, foreign employees without a C settlement permit who are resident or staying in the canton, as well as cross-border commuters whose place of work is Geneva. The competent authority is the Administration fiscale cantonale (AFC).

02

NOV & quasi-residents

From a gross annual income of CHF 120'000, the subsequent ordinary assessment is compulsory – once assessed, it stays that way. Cross-border commuters resident in France who pay tax in Switzerland on at least 90 per cent of their worldwide income can apply afresh each year as quasi-residents (DRIS/TOU) – by 31 March of the following year without fail.

03

How we support you

We check the tariff code, marital status, other income and possible deductions and assess whether a NOV or quasi-resident status is worthwhile in your case. We then submit the application on time and prepare the complete tax return.

The information is for guidance only and does not replace an individual assessment. We check your specific situation before processing.

From the Canton of Geneva

Typical situations in the Canton of Geneva

Withholding tax payers and cross-border commuters

Geneva has a particularly large number of people taxed at source and cross-border commuters. Anyone living in France who pays tax in Switzerland on at least 90 per cent of their worldwide income can, as a quasi-resident, apply afresh each year for a subsequent ordinary assessment (NOV) – and thus claim deductions.

Deducting high health insurance premiums

Geneva allows health insurance premiums to be deducted up to twice the cantonal average premium – in 2025 up to CHF 17'122 per adult. This is uniquely generous in Switzerland and is often not used in full.

Commuting with a capped deduction

When it comes to the travel expenses deduction, by contrast, Geneva is strict: at cantonal level, a maximum of CHF 534 is deductible in 2025 – for all means of transport combined. This makes it all the more important that the remaining professional expenses and deductions are recorded in full.

International organisations

Special rules apply to employees of international organisations depending on the headquarters agreement – from full exemption to normal taxation of individual components of income. We clarify what needs to be declared in your case.

Property and imputed rental value in the Canton of Geneva

Anyone who owns residential property in the Canton of Geneva pays tax on the imputed rental value (valeur locative) as income and can in return deduct mortgage interest, maintenance and administration costs. What matters is a clean separation: repairs and replacements preserve the value and are deductible; an extension increases it and is not.

In addition, Geneva levies the supplementary property tax (impôt immobilier complémentaire): 1 per mille of the tax value without deduction of debts, reduced to 0.2 per mille for the owner-occupied main residence. We record all items and compare the lump-sum and effective deduction for maintenance.

If your property is located in another canton or you own several properties, a tax allocation is made between the public authorities involved. We record all properties in full.

  • Imputed rental value and property details recorded correctly
  • Mortgage interest and list of debts checked
  • Maintenance: value-preserving separated from value-enhancing
  • Lump-sum or effective deduction compared
  • Properties outside the canton taken into account

Additional service: CHF 65.– per property.

Communal comparison

Communal centimes additionnels in the Canton of Geneva

Instead of a tax multiplier, the 45 Geneva communes levy additional centimes (centimes additionnels) on the cantonal basic tax – in addition to the cantonal surcharge of 47.5 per cent (less 12 per cent tax rebate, plus 1 per cent home care).

In 2025, the range runs from 25 (Genthod, Cologny) to 51 additional centimes (Avully, Chancy) – roughly double. Depending on where you live, your tax burden can differ considerably; this makes a tax return that makes full use of all permissible deductions all the more important.
