Korea's second housing property tax instalment is due 16-30 September. A single-home owner with a 500 million won assessed value pays 620,000 won a year, half of it now. The urban planning surcharge often exceeds the base tax itself.
A single-home household pays no jongbuse (comprehensive real estate holding tax) below 1.2 billion won in assessed value, and only 60% of the excess enters the tax base. A 2bn-won home computes to 2.76 million won. Every step calculated.
Housing property tax in Korea is billed in two halves, in July and September — unless the base tax is 200,000 won or less, in which case July settles it. Worked calculations for assessed values of 300m, 500m and 800m won.
Jongbuse sums a person's declared home values, subtracts 1.2 billion won for one-home owners (900 million otherwise), and multiplies the rest by a 60% fair-market ratio to set the tax base. Rates run 0.5-2.7%, up to 5% for three-plus homes — worked by declared-value case.
Residential property tax is assessed in full against the June 1 owner. One day shifts who pays for a full year. From assessed value through the fair market ratio and progressive rates to the bill, plus the July/September split structure — with this year's Seoul levy data (residential +15%).
