The short answer

In the Canton of Valais, the tax return for tax year 2025 must be filed by 31 March 2026; the deadline extension is obtained by paying CHF 20 before this date and applies to employees until the end of July. We prepare your tax return at a fixed price per tax year: CHF 35.– for apprentices and students, CHF 99.– for individuals, CHF 149.– for married couples and families.

Cantonal knowledge

Tax return in the Canton of Valais: what you should know

The Valais tax law applies equally throughout the canton – but how much you pay in the end depends on the coefficient of your commune and on the deductions claimed.

Specialist discussing tax documents with a client

122 communes – and a system without a tax multiplier

Valais calculates differently from most cantons: instead of a tax multiplier, the 122 communes apply a coefficient to the tax amount – in 2025 between 1.00 (for example Brig-Glis and Zermatt) and 1.45 (Leukerbad) – combined with an indexation specific to each commune. The canton itself levies its tax according to the tariff with an indexation of 173 per cent.

For your tax return, this changes nothing about how the details are recorded: what counts is your commune of residence and, if you move within the canton, in principle the one at the end of the year. We clarify such points before processing.

VSTax – the tax return software

The canton provides free software with VSTax (available from the end of January each year). The tax return can be filed electronically with it, including receipts – with a correction window of 15 days after transmission; receipts can be photographed via the app.

VSTax 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 in full, we take care of it for you: we enter your details, discuss the draft with you and prepare the submission.

Typical mistakes that cost Valais taxpayers money

In practice, we see the same points again and again: the deadline extension is missed because the payment of CHF 20 must be made before 31 March. The tax reduction of 35 per cent per child is confused with the child deduction or forgotten. For travel expenses, the new rate of 75 centimes per kilometre is not used.

The wealth tax allowances increased as of 2025 – CHF 90'000 for married couples and CHF 45'000 for single persons – are also often overlooked. A specialist checks every item individually and points out missing receipts to you before the return is filed.

Tax deductions in the Canton of Valais: making the most 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 (cantonal and communal taxes); the official guidelines are authoritative.

  1. 01

    Professional expenses & commuter deduction

    Valais has no cantonal upper limit for the travel expenses deduction; for cars, a new rate of 75 centimes per kilometre applies up to 15'000 kilometres, degressive above that (tax year 2025; at federal level, the cap of CHF 3'300 applies). In addition, meals away from home at CHF 15 per working day or a maximum of CHF 3'200 per year.

  2. 02

    Child deductions & tax reduction

    Graduated child deduction: CHF 7'860 up to the age of 6, CHF 8'940 up to the age of 16, CHF 11'930 above that – plus an additional CHF 1'240 from the third child. On top of this comes the Valais tax reduction of 35 per cent per child applied directly to the tax amount (at least CHF 680, at most CHF 4'900; tax year 2025).

    Official source(opens in a new tab on vs.ch)
  3. 03

    Third-party childcare

    Documented costs for third-party childcare are deductible up to CHF 10'000 per child (tax year 2025, increased as of 2025). One of the conditions is that both parents are gainfully employed – we check the details.

  4. 04

    Insurance premiums & savings interest

    Deductible up to CHF 7'240 for married couples or CHF 3'620 for single persons, plus CHF 1'130 per child (tax year 2025) – regardless of whether contributions were made to a pension fund or pillar 3a.

  5. 05

    Pillar 3a & further education

    Payments into tied pension provision are deductible up to CHF 7'258 (tax year 2025, employees with a pension fund). Job-related education and further education: in Valais up to CHF 12'550 per person and year (federal level: CHF 13'000).

  6. 06

    Donations & charitable contributions

    Voluntary contributions to tax-exempt charitable institutions domiciled in Switzerland as well as contributions to political parties, each 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.

The date on your personal tax documents is always authoritative. The following overview refers to tax year 2025.

Deadlines at a glance

Ordinary filing deadline
31 March 2026 for tax year 2025 (dispatched in February)
Deadline extension
Payment of CHF 20 before 31 March counts as an application – employees until 31 July, self-employed persons until 31 October 2026
Electronic tax return

Missed the deadline? No need to panic.

The Valais deadline extension works via the payment: anyone who transfers the CHF 20 before 31 March has automatically extended – employees until the end of July, self-employed persons until the end of October.

If the deadline has already passed, a reminder usually follows first. In this case, get in touch early – we clarify with you what is still possible and take over further communication.

We take care of your deadlines in good time – our service for this is included in the package price; the cantonal fee of CHF 20 is invoiced directly by the canton.

Withholding tax

Withholding tax in the Canton of Valais

If your salary is taxed directly at source, an ordinary tax return is not automatically necessary – but in certain cases it is mandatory or possible on a voluntary basis. In Valais, the cross-border commuter rules with Italy and France come on top.

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. The withholding tax section of the Cantonal Tax Administration of Valais is responsible.

02

NOV – subsequent ordinary assessment

From a gross annual income of CHF 120'000, the subsequent ordinary assessment (NOV) is mandatory – in Valais also, for example, in the case of additional assets or real estate. Below that, it can be requested voluntarily, by 31 March of the following year.

03

Cross-border commuters from Italy and France

As a border canton, Valais applies the new cross-border commuter agreement with Italy (eighty per cent of the withholding tax for new cross-border commuters since 2024, assessed in Italy with a tax credit); with France, the cross-border commuter arrangement applies, under which no Swiss withholding tax is levied if a certificate is provided. We check your situation before processing.

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

From the Canton of Valais

Typical situations in the Canton of Valais

Holiday and second homes

In Valais, the full imputed rental value of a holiday home is taxable – regardless of how often it is used. For those resident outside the canton, limited tax liability and tax allocation come on top. We declare your properties correctly and in full.

Families with the Valais tax reduction

In addition to the graduated child deduction (CHF 7'860 to 11'930), Valais has an additional reduction applied directly to the tax amount: 35 per cent per child, at least CHF 680 and at most CHF 4'900 (tax year 2025). We make sure that both are applied correctly.

Cross-border commuters from Italy and France

Valais is a border canton under the new cross-border commuter agreement with Italy (eighty per cent of the withholding tax for new cross-border commuters since 2024) and applies the cross-border commuter arrangement with France. We clarify which rules apply to you before processing.

Bilingual documents

Upper Valais German, Lower Valais French: forms and rulings are issued in different languages depending on the region. We assign every item correctly regardless of the language and support you in German.

Property, imputed rental value and holiday homes in the Canton of Valais

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

Important for holiday homes: in Valais, the full imputed rental value is taxable – regardless of how often the home is actually used. For those resident outside the canton, there is limited tax liability with tax allocation between the cantons.

As of 2025, Valais has also increased the wealth tax allowances by half: CHF 90'000 for married couples, CHF 45'000 for single persons – which directly relieves property owners.

  • Imputed rental value and property details recorded correctly
  • Holiday home: full imputed rental value declared correctly
  • Mortgage interest and list of debts checked
  • Maintenance: value-preserving separated from value-enhancing
  • Tax allocation taken into account for residence outside the canton

Additional service: CHF 65.– per property.

Communal comparison

Communal coefficients in the Canton of Valais

Valais has no tax multiplier: the communes apply a coefficient to the tax amount, combined with an indexation specific to each commune. A low coefficient generally means a lower tax burden. The following selection shows the coefficients of larger and well-known communes.

In 2025, the coefficients range from 1.00 (including Brig-Glis and Zermatt) to 1.45 (Leukerbad); on top of this comes the commune-specific indexation, which can shift the picture slightly. This makes a tax return that fully exploits all permissible deductions all the more important.
