This will not show where the money came from or how the money was brought into the country.
AFIP wants to know the source of the funds, i.e. how they were legally earned or acquired.
When it comes time to sell it's a good idea to be able to show exactly how the funds (equal to the peso value stated on the escriitura at the official exchange rate at that time) were acquired.
Bringing in amounts just under $10K USD a number of times might be useful if the buyer is paying a portion of the "real" price en negro.
Hi, thanks for your useful advice, I really appreciate it. It is a difficult issue. The proving of source isn´t difficult - the account overseas, such as it is, is well documented - I am not exactly Rockefeller. But how to get this money into the country in cash? I want to spend about 180K, and apart from these ´courriers´, which seems a bit dodgy, the only concrete suggestion is the buying of stocks. D´you think that this is feasible? As to the justification, I have made about a dozen trips, so that is covered - assuming up to 1/3 of the real price will be paid en negro. Cheers, Sarah
