Bienes Personales is not new, nor are the penalties. If you own real estate or even a car, bike or household furniture in Argentina, you have a liability to file Bienes Personales and pay taxes if the value is over a certain amount. Likewise if you are an Argentine tax resident and own real estate abroad, you also need to include these in your filings along with any foreign bank account balances, investment funds, cash, shares etc.
The recent issue in the city of Buenos Aires I heard about is that AFIP have reclassified how real estate in CABA shall be valued to calculate the Bienes Personales tax due - this means properties are now valued at 500%+ more than they were up until last year pushing around 200.000 more apartments in CABA into the taxable bracket (ARS6mm for secondary properties and ARS 30mm for the primary family home) as well as increasing the total tax due.
El mínimo no imponible es de $6 millones. Con el aumento de 505,6% en la valuación de los inmuebles, más de 200 mil propiedades superarán ese piso.
