Thank you for answering.
Beside WHT, I meant to write CIT as well.
I'm sharing this in order to test advised tax planning.
Tax optimization is intented and not tax avoidance.
A scenario is that Swiss branch will perform invoicing for services in SFr to foreign b2b clients in jurisdictions where Swiss VAT isn't applicable.
So, without WHT, branch would be taxed with 8.5% federal CIT and cantonal one - effective between 11.9% and 21.0%?
If a foreign HQ︀ is in Delaware, USA, the maximum effective CIT would be 21% as a federal one;︁ no Delaware CIT as income was overseas.
Switzerland and USA has a tax treaty, so︂ up to maximum 21.0% CIT is what we would pay?
Did I lost something in︃ this setup?
