Detailed explanation

What is the Korean 3.3% tax?

Many foreign freelancers in Korea notice that a client pays less than the invoice amount and says “3.3% tax” was withheld. This is a common withholding pattern for certain service payments. It usually means the payer withheld tax before paying you and may report the payment to the tax office. It does not, by itself, answer whether your final tax is paid, whether a refund is possible, or whether you need to file.

The important point is that withholding is a prepayment or reporting mechanism, not a personal tax review. Your total income, other income, residency position, and available records may all affect the final result.

How should freelancers check their situation?

Start with a list of clients, payment dates, gross amounts, withheld amounts, and any statements you received. Then compare that list with Hometax records if you can access them. If a client did not report correctly, the system may not match your own records. If you worked for foreign clients or received income outside Korea, the question can become more complex and may require professional advice.

Separate the gross fee, national tax, and local tax

The NTS prefilled-refund guidance explains the common 3.3% personal-service withholding as 3% national income tax plus 0.3% individual local income tax. The NTS rate table distinguishes resident business-income withholding from other income and nonresident categories. Do not apply 3.3% to every foreign contractor solely because of a visa or job title.

Illustrative payment, not a tax assessment: a KRW 2,000,000 gross fee subject to this withholding produces KRW 60,000 national withholding, KRW 6,000 local withholding, and KRW 1,934,000 paid to the bank. Record all four numbers. A net bank deposit is not the same as gross business revenue, and the withheld amount is not a deductible operating expense in this illustration.

Build a reconciliation sheet before choosing a return

Use one row per payment. This practical worksheet is a record-checking tool, not an official filing form.

Keep an unresolved-items column. For example, if one client’s payment is missing, save the invoice and ask the client about its reporting rather than deleting that payment from your own records. If a figure is duplicated, identify the underlying payment before changing the return.

Understand what a refund comparison tells you

For the same national tax and period, comparing final tax with credited prepayments indicates whether there is an amount to pay or potentially refund. The NTS refund guidance explains why previously withheld tax can exceed final tax. It does not promise that everyone who had 3.3% deducted receives that money back.

Arithmetic illustration only: if credited national withholding is KRW 360,000 and the final national liability is KRW 240,000, the difference is KRW 120,000. This assumes the final liability has already been correctly established. It does not calculate expenses, deductions, residence, penalties, other income, or local tax. A different final liability could leave additional tax to pay.

After preparing the numbers, use the return preparation guide. Keep the national return acceptance, any local-tax filing confirmation, and payment or refund records separately. An estimated refund on a draft screen is not evidence that money has reached your bank.

How do refunds usually get checked?

After filing or after a refund is processed, Hometax may show refund status or payment status. Timing and display can vary, so use the refund status procedure for general navigation. Be careful with services or people who promise a refund before reviewing your records. Refunds are not guaranteed.

If you are new to the topic, read the income tax filing guide first, then the Hometax filing procedure.

Documents you may need

• Payment statements from clients
• Withholding receipts if available
• Hometax login
• Bank account information
• Expense records when relevant and supportable

Common mistakes

• Believing every 3.3% deduction creates a refund
• Not checking whether clients reported payments
• Ignoring income from multiple clients
• Using unsupported expenses

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.
