Alleged tax or temporary levy that became permanent. It is a levy that financial institutions charge every Colombian who makes withdrawals from their accounts (whether savings or current), in payments and in transfers. It was created in 1998 and initially it was only 2 per thousand. ( It's a little concealed robbery).
In Colombia, the four per thousand ( 4X1000), also known as the Financial MovementS Levy (GMF), is a tax that applies to some financial movements, specifically to withdrawals from savings accounts and current accounts.
