What taxes will I need to pay if I resell my Swiss property?

When you resell your property you will be liable to capital gains tax charged by the canton on the difference between the sales price and the purchase price. When calculating the tax you can deduct the purchase and sales costs (notary fees, sales agent commission) and any special renovations or improvements to the property. The rate of the capital gains tax decreases with each year of ownership, so for example, in Valais it starts at 30% (if you sell within a year) and decreases to 9% after 10 years and down to 1% after 25 years.

You may be liable to pay tax in your country of domicile but Switzerland has a dual taxation treaty with most countries so you will get a credit for any tax paid in Switzerland so you do not pay tax twice.
