If the US LLC has a PE in Qatar, wouldn't it be treated as a Qatari company, meaning 10% tax? Or do you use a Qatar Freezone company structure? OP, please elaborate.
From a point of interest, how does it work in practice to register a company in Qatar? Is it as easy as in Dubai or does it require something else to be allowed to set up a company there, and above all, what are the requirements for a free zone company?
I don't think GCC countries really have a concept of "PE". The UAE is probably the first to really implement this.
But then again, would you really want to be the one to find out?
If Qatar freezone companies are 0%, why not set up one there and then use that to bill your US LLC? Seems like a safer approach to me.
The exact rules aren't even clear for the UAE, which has already implemented much more in terms of taxes.
There was a thread here somewhere where someone mentioned he asked a high-profile law firm in Dubai to check this for him - and they ended up refunding him because they didn't know and couldn't find out.
Why would you expect this to be clear in Qatar?!
