DA-1 incomplete because Interactive Brokers not registered in CH

Hi, I got a reply from the tax authority that my DA-1 won’t be completely refunded since IB sits in the UK and is not registered in CH. Is that correct? Any thoughts?

I guess you tried to ask for the extra US withholding, that’s only valid for a Swiss broker. Classic error :slight_smile:


I think you filled it out wrong. Should be like that:


By the way, consider yourself “lucky”, you also probably asked for a lot more than was withheld for BND. Withholding for US bonds are well below 15% (usually more like 1-2%).

For the one that use GeTax in French/English is there the kind of option as well ?

Yes. You have to disregard the " retenue supplémentaire d’impôt".
