You're wrong.
This is my reading of the above:
- 1st part: If as a Panamanian resident, you don't have Panama-sourced income, there's no taxes
- 2nd part: If you are KPMG or some international corporation with work being done inside Panama, remittances back to the international corporation would be subject to withholding taxes. Same goes if you're not a Panama resident and doing work from here. You'd be subject to 15% withholding taxes
- 3rd part: It's related to things like interest earned inside Panama by a non-resident
So the 2nd and 3rd part are for non-residents mostly.
1st part confirms there's no taxes for us.
