Defaults apply to both tax year 2025 (settled early 2026) and tax year 2026 (settled January 2027): the rates, income tests and cap are the same in both. Restriction of Special Taxation Act Art. 95-2: salary up to KRW 80M and global income up to KRW 70M → 15%; salary up to KRW 55M and global income up to KRW 45M → 17%; rent counted up to KRW 10M a year (for rent paid from 1 Jan 2024). From tax year 2026 a spouse living at a different address can also claim (Act No. 21223, KRW 10M combined); that is not modelled here. Also, a decree change (27 Feb 2026) allows up to 100 m² for households with three or more children or grandchildren. The 10% local-tax credit is Local Tax Special Cases Act Art. 167-2 (through 31 Dec 2026). If the law changes, edit the numbers here.

This is an estimate for reference. It follows Korea's Restriction of Special Taxation Act Art. 95-2 and 122-3 (tax years 2025 and 2026) and covers your own credit only. The real figure depends on the order of other deductions and credits, your final tax, the housing and household conditions and day-based pro-rating of rent. The spouse add-on from tax year 2026 (Act No. 21223) is not modelled. Check your employer's year-end settlement (withholding statement), the National Tax Service's Hometax year-end service or the NTS call centre (126). This is not tax advice.

What this tool does

Enter your total salary, global income and the rent you paid in the year to get the Korean monthly rent tax credit for tax years 2025 and 2026 (settled in early 2026 and January 2027, with the same rates and limits): the credit rate, the credit itself and the total saving once local income tax is included. A checklist covers the home-ownership, housing-size and address conditions, and the rates and limits can be edited under 'Edit the rules'.

How it is calculated

Employees qualify with total salary up to KRW 80M and global income up to KRW 70M; the rate is 17% with salary up to KRW 55M and global income up to KRW 45M, otherwise 15%. Global income is earned income (salary minus the employment income deduction: 70% up to 5M; 3.5M + 40% up to 15M; 7.5M + 15% up to 45M; 12M + 5% up to 100M; 14.75M + 2% above; capped at 20M) plus any other income taxed globally. Qualifying business owners get 15% with global income up to KRW 70M and 17% up to KRW 45M. Credit = min(rent paid, KRW 10M) × rate, rounded down to the won. If you enter the tax left, the credit is limited to it, and local income tax falls by a further 10% of the credit applied. Example: salary KRW 48M (deduction 12.15M → earned income 35.85M) and rent of 600,000 × 12 months = KRW 7.2M gives 17%: a credit of KRW 1,224,000 plus 122,400 of local tax, KRW 1,346,400 in total, which is what the page shows when it opens.

Choose employee or qualifying business owner

Enter total salary (excluding tax-free pay) and any other global income; 0 if you only have salary

Enter rent as monthly × months or as an annual total, excluding maintenance fees and the deposit and only for the period after your move-in registration

To see whether you can use the whole credit, enter the tax left before this credit

Untick any condition that does not apply: you get a warning but the figures still show

Example: salary KRW 60M, rent 800,000 × 12 = 9.6M → 15% → KRW 1,440,000, or 1,584,000 with local tax

Things to know

For rent paid from 1 January 2024 the salary ceiling rose from KRW 70M to 80M, the global-income ceiling from 60M to 70M and the rent cap from 7.5M to 10M. Tax years 2025 and 2026 use the same figures.

The credit comes off your computed income tax, so anything above the tax due is lost. Early-career workers on low pay should enter the computed tax from their withholding statement to see the real amount.

Claiming the rent credit means giving up the KRW 130,000 standard credit. If you claim no other special items such as insurance or medical costs, tick that option to see the real difference.

The home must be national-housing size (85 m² exclusive area, 100 m² in non-metro towns) or have a standard price of KRW 400M or less; residential officetels and goshiwon rooms count. The lease address must match your resident registration, and the lease must be in your name or a basic-deduction dependant's.

From tax year 2026 a spouse registered in a different city or district can also claim if eligible (KRW 10M combined), and a decree change of 27 February 2026 allows up to 100 m² for households with three or more children or grandchildren. That spouse add-on (Act No. 21223) is not modelled; this calculator covers one person only.

If the credit was missed in the year-end settlement, add it in the May income tax return or file a correction claim within 5 years of the filing deadline.

Frequently asked questions

What is the maximum Korean monthly rent tax credit?

For tax years 2025 and 2026 rent counts up to KRW 10 million a year, so the credit is at most KRW 1.7 million at 17% or KRW 1.5 million at 15%, and local income tax falls by another 10% of that. If the credit exceeds your computed tax, the excess is lost.

Who gets 17% and who gets 15%?

Employees with salary up to KRW 55 million and global income up to KRW 45 million get 17%; those with salary up to KRW 80 million and global income up to KRW 70 million get 15%. With salary only, the global-income test is in practice met whenever the salary test is. It is judged on the claimant's own income, not the couple's.

Can a household member who is not the householder claim?

The householder of a home-free household on 31 December is the default claimant, but another member can claim if the householder takes no housing-related deductions such as this credit or housing-loan deductions. Eligible registered foreign workers can claim too.

Do I need the landlord's consent or a fixed-date stamp?

No, neither is a tax requirement. You need a resident registration copy, a copy of the lease and proof of payment such as bank transfer receipts, and the lease address must match your registered address.

How much do I save once local income tax is included?

Under the Local Tax Special Cases Act, an income-tax credit also reduces local income tax by 10% of the credit, so the total saving is about 1.1 times the credit applied. A KRW 1,224,000 credit, for example, cuts local tax by 122,400, KRW 1,346,400 in all.
