I am about to fill out my tax return in Geneva for 2020, and I would need help as my situation is somewhat complicated.
My wife and I live in Geneva and have been married since 2020. My wife is Indian and has been working as an international civil servant with a UN agency for about 4 years. As for me, I’m Swiss and do not work in a UN agency.
As we already knew (Les particularités fiscales | ge.ch), my wife is exempt from paying income and wealth tax as she is a foreign national and works for a UN agency (see link above). Therefore, she does not have to fill out a tax return.
However, and where things get complicated is that we have been investing in ETFs via IB since mid-2020. The IB account is registered in my name: my wife first makes her monthly payments into my bank account, and then I send everything (her payments and mine) to my IB account. The payments are split 50%-50% between my wife and me.
We also invest in cryptocurrencies and proceed as described above.
As my wife is not subject to income and wealth tax, what do I need to state on my tax return? Do I have to declare the entire Net Liquidation Value shown on the IB? Or only half, since I only contribute 50% of the payments made to my IB account?
If I only have to declare half, how do I declare dividends? On what basis can I calculate the amount of tax?
The same question applies to cryptocurrencies. Do I only have to declare 50% of our investments?
Thank you in advance for your answers!
