South Korea's tax office said Wednesday that it collected 1.32 trillion won ($1.23 billion) in taxes from suspected offshore tax evaders last year.
The National Tax Service (NTS) collected the revenue from 233 offshore tax dodgers in 2017, with the total being slightly more than the 1.3 trillion won worth of dues collected from those who tried not to pay tax the previous year, it said.
Offshore tax evasion has been on the rise in recent years, as some wealthy people have shifted their assets to tax havens in an apparent move to exploit legal loopholes.
The NTS office said it is looking into 39 individuals on suspicion that they have dodged taxation by setting up offshore entities in tax havens.
