Businesses below these revenue levels may use the simple rate; others use the standard rate. Previous year's revenue applies to continuing businesses, this year's revenue to new ones.
| Industry group | Continuing business | New business |
|---|---|---|
| Farming, forestry, fishing, mining, wholesale and retail, real estate sales, others | Under 60,000,000 KRW | Under 300,000,000 KRW |
| Manufacturing, lodging and food, utilities, construction, transport, IT and telecoms, finance, brokerage | Under 36,000,000 KRW | Under 150,000,000 KRW |
| Real estate rental, professional services, business support, education, health, arts, personal services | Under 24,000,000 KRW | Under 75,000,000 KRW |
Professionals such as doctors and lawyers always use the standard rate. Personal-service freelancers use a 36 million won threshold for the previous year.
