Hello!

Yes, AFIP is the Administración Federal de Ingresos Publicos, but I would say
the Argentine tax authority, in a translation in order to explain the concept and put the acronym in parentheses.

It's commonly used translation. Here are a couple links for you to take a look- Administracion Federal de Ingresos Publicos (AFIP)

The Argentine tax authority has issued guidelines to selected taxpayers to help resolve questions about the application of October 1999 transfer pricing regulations.

I agree with scapelao and scalesi in the translation. Mine is a bit more simple. In fact, I have found it in some English newspapers.

Good luck!!
