Korea's Monthly Rent Tax Credit: Who Qualifies and How to Claim

What the monthly rent tax credit is

Korea's monthly rent tax credit lets a worker who does not own a home subtract a percentage of the rent paid during the year directly from that year's income tax. Unlike an income deduction, which lowers taxable income, a tax credit cuts the computed tax itself, so the effect is fairly clear when you qualify. It is set out in the Restriction of Special Taxation Act, and employees usually claim it through year-end tax settlement (yeonmal jeongsan, the annual reconciliation run by the employer). It is separate from the housing fund deductions for jeonse (lump-sum deposit) tenants or owners, and it is one of the credits most often missed by young workers and single-person households renting on a monthly basis (wolse). Rent usually does not appear in the simplified year-end data that the tax office collects, so if you do not submit documents yourself the credit simply drops out. This article uses the 2025 tax year (settled in early 2026) as its basis. Figures can change every year, so check the National Tax Service's guidance before claiming.

Who qualifies and which homes count

The basic claimant is a worker who, on 31 December, heads a household that owns no home. A household member can claim if the head has not taken housing-related deductions, and foreign workers meeting certain conditions may qualify. Homelessness is judged for the whole household, so a spouse owning a home usually blocks the credit even if you live apart, and buying a home during the year removes that year's credit. For the 2025 tax year your own total salary must be KRW 80 million or less, and global income above KRW 70 million excludes you. The home must meet one of the tests below; residential officetels (studio units in mixed-use buildings) and goshiwon (small rooming units) count. The lease must be in your name or a basic-deduction dependant's. The 2025 tax reform changed some rules, such as letting spouses who live at different addresses each claim under conditions and relaxing the size test for households with three or more children; check with the National Tax Service which tax year these apply from.

• Whole household owns no home on 31 December; you are the head (or a qualifying member)
• Total salary of KRW 80 million or less (2025 tax year)
• National housing size or smaller (85 sq m; 100 sq m in towns outside the capital region) or standard price up to KRW 400 million
• Lease in your name or a dependant's

Rates, cap and the tax ceiling

For the 2025 tax year the credit rate is 17% if total salary is KRW 55 million or less (excluding those with global income above KRW 45 million) and 15% for salary above that up to KRW 80 million. Rent counts only up to KRW 10 million a year, so the maximum credit is KRW 1.7 million at the 17% rate or KRW 1.5 million at 15%. One point is often missed. A tax credit is subtracted from the tax you owe, so if the credit is larger than your final tax for the year, the excess is lost rather than refunded. People on lower salaries with little tax to begin with may not be able to use the full amount. If the lease lists rent and maintenance fees separately, the maintenance fee is in principle not counted, and the deposit never is. Checking how much rent credit actually appears on the withholding receipt from your employer's settlement makes it easier to judge later whether a correction claim is needed.

• Salary up to KRW 55 million: 17% (2025 tax year)
• Salary over KRW 55 million up to KRW 80 million: 15%
• Rent counted: up to KRW 10 million a year
• The credit can only be used up to your final tax

Documents and matching addresses

Three documents are central: a copy of the lease, a certified copy of your resident registration (deungbon, the household register extract), and proof that you actually paid, such as bank transfer records or deposit slips. The most common reason for rejection is an address mismatch. The address on the lease must match your registered address, so if you registered your move late, rent for the period before registration may not be accepted. Check that the building and unit numbers are written the same way. A fixed-date stamp on the lease is not a requirement for the credit, but it is worth getting to protect your deposit. Paying in cash weakens your proof, so use transfers and make sure the recipient matches the landlord named on the lease. Hometax also lets you apply to have rent payments recorded as cash receipts. At year-end, submit these documents with the rent credit statement in the way your employer specifies.

• Copy of the lease (in your name or a dependant's)
• Resident registration extract matching the lease address
• Bank transfer records or deposit slips
• Your employer's rent tax credit statement form

A worked example

The following is an assumption to show the structure. A homeless household head with total salary of KRW 48 million lives in a 30-square-metre studio and pays KRW 600,000 a month for 12 months. Annual rent is KRW 600,000 × 12 = KRW 7.2 million. Because salary is KRW 55 million or less, the 17% rate applies, so the credit is KRW 7.2 million × 17% = KRW 1,224,000. If this person's final tax after other deductions is larger than that, the full credit reduces tax. If the same person paid KRW 1 million a month, annual rent would be KRW 12 million, but only KRW 10 million counts, so the ceiling is KRW 1.7 million. Conversely, if salary were low and final tax only KRW 800,000, tax would fall by KRW 800,000 and the rest of the KRW 1.22 million credit would be lost. Actual results depend on other deductions and tax already withheld, so a take-home pay calculator and the year-end settlement preview on Hometax are useful for a rough estimate.

Common misconceptions

Most misunderstandings about this credit involve the landlord. Under tax law the landlord's consent is not needed, and it does not matter whether the landlord is a registered rental business. However, if you promised in the lease not to claim the credit, a contractual dispute could arise separately from tax law, so it is better to raise it before signing. Some people also think only household heads can claim, but household members can if the head has not taken housing-related deductions. On the other hand, if your registration stays at your parents' home while you rent elsewhere, the address mismatch usually blocks the credit. Frequent misconceptions include the following.

• 'The landlord must agree' — consent is not a tax requirement
• 'You need a fixed-date stamp' — not required for the credit, though it protects your deposit
• 'Maintenance fees count as rent' — separately listed fees are generally excluded
• 'Miss year-end settlement and it is gone' — you can claim via the May tax return or a correction claim

A checklist before year-end settlement

Following this order prevents most missing papers and eligibility mistakes. First, confirm that your whole household owns no home as of 31 December and that you are the household head, or that the head is not taking housing-related deductions. Next, check that the home's floor area or standard price is within the limits. Then confirm that the lease and registration addresses match and note your move-in registration date to fix the eligible period. Download a full year of transfer records and match the recipient's name and amounts. Finally, check on the withholding receipt from your employer's settlement that the rent credit was applied. If it was left out, add it yourself during the comprehensive income tax filing period in May, or after that use a correction claim.

• Confirm household homelessness and head status as of 31 December
• Check floor area or standard price
• Check lease and registration addresses and the move-in date
• Match transfer recipients and amounts
• Confirm the credit on your withholding receipt

Frequent case 1: you prefer not to tell your employer, or it was left out

Some people leave rent out of year-end settlement because they would rather not share their address or living arrangements with their employer. You do not have to give up the credit. In May of the following year, during the comprehensive income tax filing period, you can file directly on Hometax and include the rent credit, receiving the refund without going through your employer. If that period has passed, use a correction claim (gyeongjeong cheonggu, a request to reduce tax already settled). It can be made within five years after the statutory filing deadline, so if you qualified in past years you can claim several years of missed rent credits together. You will still need that year's lease, a registration extract showing your past addresses, and transfer records. Older transfer records can usually be retrieved by setting a date range in your bank app or requesting a transaction statement at a branch. A separate article on this site covers the correction claim process in detail.

Frequent case 2: you moved during the year or the lease is in another name

If you moved more than once in a year, each home is assessed separately. Keep the lease and transfer records for each, and use your registration records to prove the periods you were registered at each address; the rent for those periods can then be added together. Periods before you registered, or spent in a home that fails the tests, are excluded. If the lease is in the name of a spouse or parent who is your basic-deduction dependant, the credit may still be possible, but a lease in the name of a sibling or friend who is not your dependant usually is not. When sharing a flat and splitting rent with a friend, the name on the lease and the person actually paying need to line up, so be careful. If the rent changed during the lease, keep the amended contract or written agreement. When the situation is unclear, it is safest to explain the facts to the National Tax Service's tax consultation centre and get confirmation.

Limits and disclaimer

This article explains the general structure of Korea's monthly rent tax credit on the basis of the 2025 tax year. Income thresholds, rates, caps and housing tests can change with tax law each year, and some changes, like those in the 2025 tax reform, apply from a specific tax year. The calculation example is an assumption to show the structure and may differ from actual tax. Whether you can claim depends on household make-up, other income and the details of the home, so check the year-end settlement guidance on Hometax, the National Tax Service's tax consultation centre, and the text of the Restriction of Special Taxation Act on the Korea Legislation Research Institute's National Law Information Center. If your situation is complicated, consult a certified tax accountant. This article is general information setting out criteria, not tax advice. If someone contacts you offering to collect a refund for a fee or asks for personal data, first confirm that they are an official body.
