Year-end tax settlement
Year-end settlement is called "the thirteenth salary". Claim it and you get money back; skip it and you don't.
What it is
A process comparing and reconciling the tax withheld each month with the tax actually due.
- Overpayment is refunded.
- Underpayment is collected.
- It is usually handled through your employer early in the year.
Steps
- Follow your company's guidance — usually in January or February.
- Download your data from Hometax's "simplified year-end settlement service" — medical costs, insurance premiums, card spending and more are gathered automatically.
- Prepare additional documents. Items not captured by the simplified service (some donations, monthly rent) must be gathered yourself.
- Submit to your employer.
- Check the result — it is reflected in your salary.
Deduction items and requirements change every year. Always confirm the current rules on Hometax or with 126.
Worth claiming (main items)
- Medical expenses — treatment receipts. See medical-records.
- Monthly rent — deductible if you qualify. The contract and transfer records are needed.
- Insurance premiums and pensions
- Education costs
- Donations
- Dependants — family members meeting the requirements.
If you don't work for a company
You settle through the comprehensive income tax return (usually in May). This applies to freelancers and sole traders. Ask 126 or a tax office.

Questions people ask
Do foreigners do year-end settlement? Yes, if you have employment income. Special provisions may apply to foreigners — check with 126.
Can I claim family in my home country as dependants? Requirements and evidence apply. Translated and certified family documents may be needed. Check with 126 in advance.
My company doesn't do year-end settlement. File a comprehensive income tax return yourself or consult 126. Missing it means no refund.
Hometax is in Korean and it's hard. Visit a tax office or ask your company's staff for help. Use 1577-1366 interpretation alongside.
Take care
Claiming deductions falsely leads to collection with surcharges later. Don't include someone else's data or expenses you didn't actually incur. Accurate data alone still produces a refund in most cases.
