I've never heard of it. It was very improbable for someone to wire money into Argentine banks in the past for all the known reasons (crisis, cepo, etc.) so a lot of people tend to think it's impossible or that it can't be done, and many account officers in bank branches might be ignorant of procedures thus finding excuses not to find out/learn how to do it. Other people (probably like your property manager) now finding themselves in the obligation to issue invoices, inform AFIP and pay taxes accordingly are trying to find ways to remain anonymous. If they receive any kind of deposit (local or international) into their bank account they might be exposed before AFIP if they are not registered in a tax category equivalent to their income level. This might be why your local provider is making you go through loops and hoops. The knot it tightening and soon anyone doing any kind of business will have to hold a bank account to be able to operate (resolución general (AFIP) 3990-E states that monotributo monthly payment for categories D and upwards must be paid by bank debit/credit card or electronically, and by November so will categories A, B & C)
I should mention that my property manager would not be taxed on money sent to my Argentine bank account.
Also, just now I´ve heard that the contractor who needs the money is willing to accept payment by Western Union, ec. and that IVA will be paid ! I don´t
recall another business person in Argentina willing to accept payment this way !
Thanks so much for all your info, which will benefit me greatly !
