Hi, I am a sole trader working here in Zurich and am trying to find out what the minimum accounting requirements are for tax return purposes.

i.e. is a cashbook and records of expenses, receipts all that is legally required?
I am worried that this is a bit light on paperwork for Swiss standards!

Tried a lot of the official swiss sites; gruenden, admin.ch, steueramt......
but can't seam to find any info.

Any advice or help would be much appreciated.

Cheers,

G.
