You each buy for the (import to CH) value of Chf300.
You have an Ausforschein from the meat supplier detailing what you`ve bought, plus the tax you paid the butcher.
The customs deduct the Euro tax and you pay tax on the Chf amount (because you are going to be refunded by the butcher the Euro tax (? are you doing that?) You only pay the Mwst once, but you have to pay it somewhere, so if you are paying Swiss tax then you claim back the italian tax. Or you pay the Italian tax and the full import duty to the Swiss per kg of meat.
If you are going to claim back the Italian tax, get your Ausforschein stamped by the Italian customs , go to the Swiss side and pay the tax on the full amount, plus duties on the 18kg extra.
Example:
We buy stuff in Germany, for building, and we divide up the items, insulation sheeting, plumbing fittings, etc into two different invoices so as not to exceed the Sfr300 each. (I`m entitled to also buy seperate "building materials for my own renovations").
Swiss customs have assured us that they deduct the German tax, and we pay tax on the nett value . You don`t pay tax on tax.
I have. If she starts talking about a new patio... run!
Not completely accurate. If you don't claim back the VAT from the source country, you must still pay it to the Swiss authorities (amount after source VAT, allowances notwithstanding).
