How reliable is this figure

Graded low — treat this as a starting default, not a fact. The rate for São Tomé and Príncipe has not been verified against an official source, and it may be out of date or may not apply to your kind of supply. Check it with your accountant or the São Tomé and Príncipe tax authority and set your own rate before you issue anything.

Whatever the grade, your own setting always wins — a rate you enter overrides the registry everywhere, including on documents already dated in the past.
