property abroad valuation

Hello together

Since we have to file the tax return/declaration for each year, and it is known that property abroad is also taken into account for asset. However, how do we have the estimated value for the property for a given year?

- how accurate it is required?

- it is required to have each year value evaluated?

I mean, through some consultation, we got a PDF about market price indication of that given year, however, the problem is that, when declare the year for tax return e.g. for 2021, and if that market price estimation/indication is not accepted (e.g. due to whatever reason such ass it's not someone who went inside the property and use some ruler to measure accurately etc.), it's now impossible to have the accurate numer for 2021 (which is already 2 years passed, especially it's property abroad and now it is extremely inconvenient to manage).

By some search over Internet, it seems the estimated value is quite reasonable in the country/region, but just not sure how strict the requirement it could be here in CH.

Many thanks if someone could share some insights.

I googled it once and it seems different cantons have different views, some for example seem to accept insurance rebuild cost. 'buy it now' valuations might be sufficient. General advice seems to be put in a number and if they don't like it they'll tell you. You could work backwards by coming up with a rental figure and seeing what value the tax system estimates based upon that. My house is probably valued at about a third of its market value.

Many thanks.

So, you mean, the property insurance will have such number of valuation? e.g. per year? if I ask them 2021, or 2022, they might be able to have better picture?
