In brief, I’m leaving CH shortly for good. I’m buying a house in England with my brother and sister (both resident in UK). I’m taking roughly £200K out of an investment account and paying it into the pot for the cash purchase. For my final tax declaration here I want to be able to say that my investment account is £200K lower than last year but that I now own UK property worth £200K I.e. everything balances quite transparently. But I don’t really want the tax authorities to ask for details of the house and the finances as my name isn’t registered as part owner. (It’s in the names of my two siblings as it simplified the legal complexity of having a property part-owned by a non-resident. We will amend the Land Registry details later, when I’m officially UK-resident again.)
Will the Swiss tax office be happy with the declaration 'UK Property value £200K' or do they ask for property details, address, finance arrangements etc.? If I was planning to go on living in CH indefinitely I’d explain things in more detail to the tax office but as I’m leaving Switzerland literally a week or so after the purchase is completed, I would much prefer not to have this extra last minute complication of having to produce documentation and explain the legal arrangement we’ve agreed.
Can someone reassure me on this? Thanks.
