3.3% Freelancer Tax
Who this guide is for
- Foreigners registering a Korean sole proprietorship
- Freelancers becoming VAT-registered
- Creators and consultants selling to Korean businesses
- Simplified taxpayers approaching a status change
Quick Answer
Korea's simplified and general VAT regimes differ in eligibility, VAT calculation, input-tax treatment, invoicing, and filing. Status is not based on nationality and is not always a free choice. Expected or prior sales, industry, place of business, related businesses, and customer needs can affect classification, so verify the registration result before pricing or issuing invoices.
Key points
- VAT status is separate from whether income tax must be filed.
- Eligibility depends on statutory business facts and thresholds.
- General taxpayers usually calculate output VAT less eligible input VAT.
- Simplified taxpayers use a different calculation and can face invoice limitations or special rules.
- A status change can affect prices, contracts, and record keeping.
Detailed explanation
Confirm classification before quoting prices
Read the business registration certificate and Hometax profile. Determine whether quoted prices include VAT and whether business customers expect a tax invoice. Correcting a contract after registration is harder than pricing correctly from the start.
Compare the calculation mechanics
A general taxpayer normally calculates output VAT on taxable sales and subtracts eligible input VAT supported by proper evidence. A simplified taxpayer uses special rules based on sales and the relevant business category. Refund, credit, and invoice outcomes can differ.
Review eligibility beyond revenue
Industry exclusions, business location, related businesses, prior activity, and other statutory facts can matter in addition to sales. Do not rely on a single threshold quoted without a tax year.
Plan for transition
If growth is likely, keep purchase and sales evidence at the standard needed for general VAT. Review open contracts, invoice wording, cash flow, and prices before a conversion date.
Documents you may need
- Business registration certificate
- Expected and prior-year sales
- Industry and business-location details
- Customer contracts
- Purchase tax invoices
- Sales invoices and card records
- Hometax VAT notices
Common mistakes
- Treating simplified status as a complete tax exemption
- Adding VAT without checking the contract and registration
- Assuming all purchases create the same input credit
- Ignoring invoice obligations
- Missing an automatic status change after sales grow
When should you ask a tax professional?
Ask a qualified tax professional if you have income from several countries, business income, unclear tax residency, treaty questions, missing documents, late filing concerns, or a visa situation that depends on tax records.

FAQ
Can a foreigner be a simplified VAT taxpayer?
Nationality alone is not the deciding factor. The business must satisfy the statutory eligibility rules for its sales, industry, location, and related facts.
Is a simplified taxpayer exempt from income tax?
No. VAT classification and individual income tax are separate systems.
Which status is better?
It depends on sales, input costs, customers, invoice needs, pricing, and expected growth. A lower administrative burden is not the only factor.
Can the status change automatically?
Yes. Sales and other facts can cause a later conversion, so review NTS notices and thresholds each year.
