I have a property in a foreign country. I used the price equivalent in CHF for my 2018 Swiss tax filing. As Swiss franc has gone up against the foreign currency over 2019, I used an adjusted (lower) price in CHF on my 2019 fillings. In the tax documents that I got from Swiss authorities, they have used the same property value I filled in 2018 for my 2019 calculations and did not take into account the adjusted lower value that used on my 2019 filings.

I am new to Swiss taxes and I would appreciate if anyone in the forum could share their experience/expertise on this topic.

Thank you in advance,
John
