Easier when split by stage
Property taxes in Korea look complicated because there are so many, but they fall into place once you sort them by when your relationship with the home changes: taxes when you acquire it, taxes every year while you hold it, and taxes when you sell at a gain. On top of these come tax on rental income and taxes on giving or inheriting a home. This guide does not cover rates. Rates and deductions change often and depend on personal circumstances, so it is more accurate to understand the concepts and check the official calculation.
Buying: acquisition tax
Acquisition tax is a local tax due when you obtain ownership by buying, receiving a gift or inheritance, or building a new home. Local education tax is added to it, and in some cases a special rural development tax too. The amount depends on the price, the number of homes you own, the region and the floor area. It must be filed and paid within a set period, and in practice it is paid before applying to register the ownership transfer. Leave it out of your funding plan and you may be short on balance day, so check the expected amount before signing.
- Who: the person acquiring the home
- When: within a set period after acquisition, usually before registration
- To whom: the local government
- Added on: local education tax, sometimes special rural development tax
Owning: property tax
Property tax is a local tax paid every year while you own a home. That year's tax is charged to whoever owns the home on 1 June, so paying the balance just before or after that date changes who pays for the year. It is calculated not from market price but from the officially assessed price the government sets each year. For housing it is usually billed in two parts, in July and September. Paying by the due date on the bill avoids penalties.
Owning: comprehensive real estate tax
Comprehensive real estate tax is an additional national tax due when the total assessed price of the homes a person owns exceeds a threshold. Like property tax, it is judged on ownership as of 1 June, and it is usually billed near the end of the year. The threshold, rates and deductions for single-home households are revised often, so they need checking every year. If you own several homes or one with a high assessed price, check the national tax service's guidance in advance to see whether it applies.
Selling: capital gains tax
Capital gains tax is a national tax on the profit from selling a home: the sale price minus the purchase price and allowable expenses. A household with one home that meets conditions such as holding and residence periods may be exempt, and long holding can bring a deduction. Selling within a short time or owning several homes can raise the burden considerably. You must file it yourself within a set period after the sale, so it is safer to check the expected tax with the tax office or a tax accountant before selling.
Expenses count only with receipts
When calculating the gain, some costs beyond the purchase price can be deducted. There are rules on what qualifies, and without proof it is hard to claim. Collecting receipts from the day you buy can reduce the tax when you sell. Costs that merely maintain the home, such as wallpapering or routine repairs, are often not allowed, so follow official guidance for specific cases.
- Receipts for taxes paid on acquisition, such as acquisition tax
- Agent's fee receipts from buying and selling
- Registration-related receipts such as the judicial scrivener's fee
- Contracts and receipts for value-adding work such as balcony extensions or new window frames
Other taxes to know about
Leasing a home for monthly rent or a deposit can create income tax on rental income, depending on the number of homes and the amounts. Giving a home to family means gift tax for the recipient, and inheriting one means inheritance tax; in both cases the recipient also pays acquisition tax. How a home is titled, for example jointly by a married couple, changes several taxes at once, so decide on the title before the contract. Decisions like these should be calculated as a whole rather than one tax at a time.
Where to check, and cautions
For local taxes such as acquisition and property tax, the local tax filing portal and the tax section of your city or district office provide guidance and simulations; for national taxes such as comprehensive real estate tax and capital gains tax, the national tax service's online portal and tax offices do. Korean tax law changes every year, and the same deal can turn out completely differently depending on the number of homes, residence period and region. This guide explains the types and concepts of tax and is not investment, legal or tax advice. Before filing or a major decision, check the latest official guidance and consult a tax accountant.
