South Koreans' tax burden is expected to reach about 340 trillion for the first time this year.
 
The government expects the national tax income to reach 257 trillion won this year, a six percent increase.
 
The local tax income is likely to rise from 75-point-five trillion won last year to 80 trillion this year.
 
The combined tax revenue is expected to reach a record 337 trillion won this year, up about 20 trillion from a year ago.
 
The ratio of tax to gross domestic product is projected to post 19-point-seven percent, possibly breaking the current record of 19-point-six percent set in 2007.
 
The figure may rise further to surpass 20 percent next year as the government is seeking to raise taxes for conglomerates and high-income earners.
