Holy smoke! Great to see you back, Steve, I think I wasn't the only one who had feared you had croaked in some robbery or due to covid or something! Glad to see it's not the case!Since the "weatlh tax" applies to temporary and permanent residents and Argentine citizens, it no doubt already has had a significant impact on expatriation. You can search for threads on the subject using key words. There was at least one expat who made it clear the "bienes personales" tax on their foreign assets would preclude seeking residency in Argentina.
As far as investments are concerned, the capital gains tax on properties purchased after January 1, 2019 (?) is likely to have a significant impact on the purchase of Argentine property as an investment..as there could be a signifiant tax levied on a "capital gain" in pesos, while the dollar amount of the sale could actually be less than the purchase price (if what one semi-retired real estate professional posted on the subject is accurate).
Long live the Hermit of the Pampas!
