Swiss Property Capital Gains Tax in Valais: What Buyers Should Know

Buying property in Valais, Switzerland? Learn how real estate capital gains tax works, why rates fall over time, and how the five-year resale restriction affects foreign owners.

When buying property in Switzerland, it is important to understand that capital gains tax is not calculated in the same way across the whole country. Property taxes are set at cantonal level, meaning the rules and rates can vary depending on where the property is located.

In the canton of Valais, which includes Alpine resorts such as Saas-Fee, Saas-Grund, Grimentz, Verbier and parts of the 4 Vallées, real estate capital gains tax is based on two main factors:

1. The size of the taxable gain

2. The length of time the property has been owned

In general, the longer the property is held, the lower the capital gains tax rate becomes.

However, there is an important distinction between foreign owners and Swiss residents.

How the rules differ for foreign owners and Swiss residents

For Swiss residents, the Valais capital gains tax grid can apply from the first year of ownership. This means that if a Swiss resident sells a property and makes a taxable gain, the relevant Valais tax rate is applied according to the size of the gain and the length of ownership.

For foreign/non-resident owners, there is an additional five-year resale restriction to consider. In Valais and Vaud, a foreign owner generally cannot resell a Swiss holiday property for a capital gain within the first five years of ownership. This rule does not apply in the same way across every Swiss canton, so the canton in which the property is located matters.

A sale within the first five years is normally only considered in exceptional circumstances, such as death, bankruptcy or proven extreme financial hardship. Where a sale is permitted, the property must usually be advertised at the original purchase price if it is sold within the first three years. After three years, only a moderate increase in line with inflation may be allowed.

The burden of proof is also high. A foreign owner may need to provide the authorities with detailed evidence, such as five years of tax returns, bank statements, wage slips and other financial records, to show that they are genuinely in a position of extreme financial hardship that only the sale of the property can alleviate.

In practical terms, the first five years should not be viewed as a high-tax resale period for foreign owners. A foreign owner should assume that they cannot make a capital gain on resale during this period. From year six onward, the standard Valais capital gains tax grid applies.

Valais capital gains tax example

For a taxable gain of more than CHF 100,001, the Valais real estate capital gains tax rate is:

*For foreign/non-resident owners in Valais and Vaud, years 1-5 should be understood as a capital-gain restriction, not simply a higher tax band. A resale during this period is generally only possible in exceptional circumstances and cannot generate a capital gain.

This is why Swiss Alpine property, particularly in Valais, is usually best viewed as a medium to long-term purchase rather than a short-term resale opportunity.

Why this matters for buyers

For international buyers considering resorts such as Saas-Fee, Grimentz or Verbier, the key point is that the first five years are not simply a period of high taxation. For foreign owners in Valais, and in Vaud, a profitable resale within that period should generally be treated as unavailable. After year five, the Valais capital gains tax system becomes more relevant, with tax rates reducing over time.

For Swiss residents, the capital gains tax grid is relevant from the beginning of ownership.

In both cases, the tax is applied to the taxable gain rather than the full sale price. This usually means the difference between the sale price and the recognised investment costs, which may include the original purchase price and certain eligible costs connected to the property.

As always, buyers should take professional tax and legal advice before purchasing or selling property in Switzerland. The final position can depend on the canton, the buyer’s residency status, the ownership structure, the type of property and the individual circumstances of the sale.
