How to use this tool
Enter displacement in cc and age in years. The embedded bands use KRW 80 up to 1,000 cc, 140 up to 1,600 cc and 200 above; the selected rate applies to the entire displacement.
Results and examples
Separate base tax from the age-adjusted amount. Year three retains 95% of the base, so distinguish a remaining percentage from the 5% reduction when reading the ratio label.
Worked example
A 1,600 cc car aged three has KRW 224,000 base and KRW 212,800 after the 0.95 factor, before education tax.
Limitations
- Education tax, annual prepayment discounts and partial-year ownership are excluded.
- Administrative age calculation and vehicle use can affect actual assessment.
