Salaried workers in South Korea are paying a record amount of income tax.

According to a new government budget report, earned income tax revenue is expected to top 30 trillion won this year for the first time ever.

Overall income tax revenue is also expected to rise more than three percent to about 65-point-three trillion won next year. That figure is based on this year's supplementary budget. 

Main opposition Democratic Party lawmakers have been pointing out that income tax from salaried workers was supplementing a lack of corporate tax, which they feel should be increased.
