Rental Income Tax in Korea for Foreign Property Owners
Income Tax
Who this guide is for
- Foreigners renting out a Korean apartment, house, office, or other property
- Non-resident owners receiving Korean rent
- Foreign residents with one or more rental properties
- Owners preparing to appoint a Korean property or tax representative
Quick Answer
Rent from Korean real estate can create Korean-source income for a foreign owner whether the owner lives in Korea or abroad. The calculation can depend on the property type, number of homes, rent and deposits, registration status, supported expenses, and whether separate or global taxation applies. Keep a property-by-property ledger and verify the current filing treatment before the May deadline.
Key points
- Korean real estate rent is not ignored merely because it is paid to an overseas account.
- Monthly rent, deposits, property type, and the number of homes can affect the calculation.
- Separate-tax and global-tax rules may need to be compared for housing rental income.
- Expenses require property-level evidence and a business-purpose connection.
- Rental income tax is separate from acquisition tax, property tax, and tax on a later sale.
Step-by-step explanation
Separate each property and payment type
Use one ledger per property. Record ordinary monthly rent, maintenance reimbursements, parking or management income, deposits, vacancies, refunds, and amounts retained by an agent. Reconcile gross tenant payments to the net amount deposited in your bank account.
Confirm residence and property facts
Your tax residence affects the wider income calculation, but Korean property remains a Korean-source item that a non-resident cannot simply ignore. Also record whether the property is housing or commercial, jointly owned, registered as a rental business, and how many homes are counted under the applicable rule.
Review deposit and housing rules
Housing rental provisions can distinguish monthly rent from deposits and may use ownership-count, value, or deposit thresholds. Because these figures and special rules can change, use the current return-year guide and do not copy a prior owner’s tax treatment.
Build an evidence-based expense file
Keep invoices, proof of payment, and an explanation for repairs, insurance, management fees, property tax, professional fees, and financing costs. Separate improvements from repairs and principal from interest. Allocate shared costs consistently if only part of a property is rented.
File and pay from the correct location
A resident may combine qualifying rental income with other aggregate income, while a non-resident may need a Korean filing contact or representative. Confirm both national income tax and the connected local income tax, and keep a Korean bank or payment plan in place if you live abroad.

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.

FAQ
Do non-resident foreigners pay Korean tax on Korean rent?
Korean real estate generally creates Korean-source rental income. The exact filing and withholding treatment depends on the owner and arrangement.
Are rental deposits treated the same as monthly rent?
Not always. Deposit-related deemed rental income rules can apply in specified housing situations, so list deposits separately from rent.
Can I deduct repairs and mortgage payments?
Some supported expenses may be relevant, but principal repayment and personal costs should not be treated as deductible rent expenses. Interest and repairs need rule-specific review.
Is rental income covered by the capital gains tax return when I sell?
No. Rental operations and the later disposal of the property are separate tax events with different calculations and deadlines.
Official Sources to Verify
Tax rules and filing procedures in Korea may change depending on your visa status, income type, tax residency, and the tax year. Before making a tax decision, always verify your situation with official sources or a qualified professional.
