Korea tax guide
Housing Loan and Mortgage Tax Deductions in Korea
Year-End Settlement
Who this guide is for
- Foreign employees with Korean mortgages
- Workers repaying qualifying housing loans
- Jeonse tenants with loan interest
- Homebuyers preparing year-end settlement
Quick Answer
Some resident foreign employees may qualify for Korean housing-related deductions or credits when the home, household, ownership, loan, lender, repayment, and timing conditions are satisfied. Eligibility is narrower than simply paying rent, jeonse interest, or a mortgage.
Key points
- Monthly rent and housing-loan benefits are separate.
- Tax residence and household status can matter.
- The home and loan must meet detailed conditions.
- Ownership and move-in dates may be decisive.
- Bank certificates do not prove every requirement.
Step-by-step explanation
Identify the housing benefit
Separate monthly rent, housing rental loan principal and interest, housing purchase savings, and long-term mortgage interest. Each has its own conditions.
Build an eligibility timeline
Record tax residence, household status, property ownership, contract date, move-in date, loan date, lender, home value, and repayment dates. Many errors come from checking only the year-end position.
Match the loan to the property
Confirm that the borrower, lender, loan purpose, property, and repayment certificate align. A general credit loan or family loan may not satisfy the relevant housing provision.
Review annually
Thresholds and permitted structures can change. Re-check the current NTS materials and employer requirements for each tax year.
Documents you may need
- Loan and interest payment certificate

Common mistakes
- Confusing monthly rent credit with loan deduction

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.
