How to disclose stocks positions to tax authorities

For your information, I used this “technique” in my tax return this year, it worked perfectly! Although the Canton of Vaud only deducted the sum of 55 CHF from the 114 CHF of VT witholdings dividends. This 55 CHF was reduced from my taxes. That’s still one less thing to pay.

As for the tax statement, I used this custom model: Interactive Brokers for dummies - #413 by xerox5003

I didn’t have any problems, so in the end, you can put all your positions (US stocks, CH, EUR, US ETF, CH, etc.) in this section and the authority will take everything into account. No need to mention European positions in another section, as I had done for my iShare SPI. They corrected by saying that this ETF was already declared in the DA-1 section.

I was hesitant to do the one-liner tax-declaration for a while, but this year I want to try it as well, since it’s such a frustrating experience to list each buy/sell and each share/ETF in the Vaud tax software.

I have two questions concerning the approach defined here:

  • i am calculating my total stock value in a separate excel sheet and use the ictax conversion rate and values. the total sum is slightly different than the number in my IBRK statement (i guess it must be conversion rates between USD/CHF/EUR etc.) - it’s about 200chf off, which value should i put in? the one from IB or the one i’ve calculated?
  • I do have US stocks, european ones, IE funds, Japanese stocks etc. Should i use the one-liner and split them per country or as @Yanikuza indicated everything into one basket (but then i wonder how do they seperate the different WHT values? someone at the tax office is going over my IB statement and recalculating the WHT by themselves?)

Make sure you calculate income from Accumulating ETFs correctly

I think you dont have to calculate yourself.
ICtax website is giving you the information.

Perhaps, i wasn’t clear enough in describing my issue. My concern was that if it’s ok to do a one-liner in the tax declaration and mention the entire amount of withholding tax for all investments as “Revenus soumis à l’impôt étranger retenu à la source”, or should I calculate them separately them by country given that they percentage of WHT isn’t the same for some countries JP (15%), CA (15%), FR (25%), De (25%) etc…

One line is fine

Super newbie here.

I understand this is good for stocks.

But how about when you have Cash in IB for which you receive Interest?

Should this be a separate line? or maybe even in a separate section?

I am not sure if I am mixing things up as this interest is not supposed to get taxed the same way as the dividends?

I simply declare cash and interests at IBKR as a bank account, in the appropriate section of the tax form. Like any other bank account anywhere else…
