Korean Freelancer Tax Calculator
Korean freelancer tax calculator with VAT, income tax, insurance, pension.
About this tool
Korean Freelancer Tax Calculator estimates quarterly VAT and the May annual income-tax filing for freelancers and one-person businesses on one page. Auto-splits between general taxpayer (10% VAT) and simplified taxpayer (1.5β4% by industry) based on revenue, applies simple-vs-standard expense rates by industry code, and computes income-tax progressive brackets (6 / 15 / 24 / 35 / 38 / 40 / 42 / 45%) plus 10% local tax, NHIS, and pension contributions. Enter the 3.3% withholding paid up front, and the tool nets it against the determined tax to show "refund / additional pay" instantly. All calculation is in-browser; revenue and expense data never leave your device.
Use cases
Scenario 1
β©50M-revenue freelance designer
Compute quarterly VAT, May income tax, and 3.3% withholding refund for a designer with β©50M revenue and β©15M expenses.
Scenario 2
Simplified vs. general β which wins?
For a β©70M-revenue business with ~30% input ratio, simulate simplified vs. general to choose the cheaper status.
Scenario 3
Predict the 3.3% withholding refund
A self-employed worker with β©40M revenue and β©1.32M withheld previews the May refund or top-up.
Scenario 4
Simple vs. standard expense ratio
Right at the β©75M boundary, compare simple-rate expenses vs. standard-rate + evidence to see how the tax shifts.
Scenario 5
Monthly progressive bracket check
As revenue ramps and the bracket jumps from 24% to 35%, simulate ahead to plan evidence collection and a CPA call.

Frequently asked
- Q. Simplified vs. general β how decided?
- A. Last yearβs revenue < β©104M qualifies for simplified; new businesses can choose simplified if expected revenue < β©48M. Cross β©80M and you flip to general automatically.
- Q. How does the 3.3% withholding work?
- A. Clients pre-withhold and remit it; in May filing itβs netted against the determined tax. Excess pre-payment is refunded; shortfall is topped up.
- Q. Simple vs. standard expense rate?
- A. Simple-rate multiplies revenue by an industry rate (60β80%) and is available below β©75M. Standard-rate uses evidence for major items (wages, rent) and rates for the rest β used at β©75M+ or by double-entry filers.
- Q. Is the May filing mandatory?
- A. Yes β May 1β31 each year for the prior yearβs income, regardless of revenue. Failure or under-reporting triggers 20% + 0.022%/day penalties.
- Q. Can I file using this output directly?
- A. It is an estimate β file via Hometaxβs auto calculation or a CPA. For revenue >β©50M or mixed real-estate / stocks / foreign income, retain a CPA.
