Income declarations for taxes for freelance company
I am starting a freelance company (unregistered) and will be hopefully working with companies in and out of Switzerland on various projects.
I was told that I would need to declare all my income every month and then pay the appropriate taxes/deductions every month as well. Does anyone know if the authorities require bank statements as "proof" or do you just tell them what you have made?
Also, does anyone know how it works with overseas accounts? I might have a client or 2 in the UK, who might pay into my UK acct for facility. Is there a specific conversion rate (government approved) that I would need to use or would I need to declare that income in Britain and not CH because it was earned from a UK company and the money would be staying there, well at least for a while? I certainly don't want to pay double tax, if you know what I mean.
Thanks for any help.
