Must-Read for Self-Employed Owners with Growing Revenue
3 Things to Check as Your Revenue Grows
The most common problem is not realizing you've crossed a revenue threshold until penalties or a tax audit follow
Switching to Double-Entry Bookkeeping
If your prior-year revenue exceeds 75 million KRW for services, 300 million KRW for wholesale/retail, or 150 million KRW for manufacturing, you become subject to double-entry bookkeeping obligations, which changes both your bookkeeping method and the non-bookkeeping penalty rate.
Diligent Filing Confirmation Target
If you exceed the industry revenue threshold (1.5 billion KRW for wholesale/retail, 750 million KRW for restaurants/lodging, 500 million KRW for services), attaching a diligent filing confirmation from a tax agent becomes mandatory, and the filing deadline extends from May to June.
Credit Card Sales Tax Credit
Individual business owners in consumer-facing industries can deduct 1.3% of their credit card and cash receipt sales (2.6% for some simplified taxpayers, including restaurants) from VAT, up to an annual cap of 10 million KRW.
Must-Read for Self-Employed Owners with Staff
If You've Hired Part-Time Staff, Don't Skip These
This is the most common reason for tax audits and Labor Ministry complaints
Hiring More Staff Can Also Earn You Tax Credits
Using the Integrated Employment Tax Credit, you can receive a tax credit proportional to the increase in your regular employee headcount. Part-time staff may qualify depending on the requirements, so it's worth checking when you hire.
Annual Tax Calendar for the Self-Employed
Simplified and general taxpayers have different filing schedules — miss these dates and penalties apply
| Category | Simplified Taxpayer | General Taxpayer |
|---|---|---|
| VAT filing | Jan 1–25 (once a year) | Jan 1–25, Jul 1–25 (twice a year) |
| Comprehensive income tax | May 1–31 filing & payment (both types) | |
| Interim prepayment | By Nov 30 (if applicable, both types) | |
If you employ staff, don't forget withholding tax filing and payment by the 10th of each month. It's also worth checking the criteria for switching from simplified to general taxpayer status in advance.
