A house in Gangnam, Seoul.



[Family of the delinquent]


"Dad, I'm from the National Tax Service."



When the door was open, the National Tax Service employees who were hiding came rushing in.



At the moment when I thought that there was nothing wrong with searching for a long time, a bundle of dollars piled up in plastic, 70,000 dollars, appeared in the corner pottery on the veranda.



He turned 85 million won from the sale of real estate into dollars and hid it.



Another delinquent country house.

Judging that the property was hidden in a house in the name of his child, he went to the site and found unopened 50,000-won bills and 100-dollar bundles of money dried on a belt.



He went to and from the bank 400 times, found 800 million won in cash and hid it, and then got caught.



There were people who used money from ordinary people in multiple stages and drove luxury cars and lived in luxury houses, and there were people who made profits by selling sales through false advertisements.



There were also many delinquents who had to hand over the real estate to their families before the compulsory collection came in.



Last year, the National Tax Service collected 2.5 trillion won by tracking these large delinquents.



This is thanks to a close look into the delinquent big data.



[Lee Eun-gyu | Head of Collection Division, National Tax Service]


"We will advance the big data system that comprehensively analyzes the property hiding suspicion system, income expenditure items, and provisional payment items in case of arrears..."



The National Tax Service selected 584 high delinquent payers based on the information collected through big data and started a follow-up investigation.
