How the calculation works
Do not multiply a market price by one rate. Follow official value, assessment ratio, taxable base, progressive rate, local additions, credits, burden cap, and split billing.

Single-home relief
A single-home household may qualify for reduced brackets when all legal conditions are met. One house in casual speech is not enough; household scope, other interests, inherited shares, and the official value matter.

Worked example
Example: with a simplified taxable base of 300 million won, ordinary housing tax reaches 570,000 won before additions. Under the qualifying single-home brackets it reaches 420,000 won. This is only a structure example, not a bill estimate.

Payment checklist
Compare the July and September notices. Check the property address, taxpayer, taxable base, rate, relief, city-area amount, local education tax, due date, and payment receipt. Card installments are not the same as statutory tax installments.

Why estimates differ
If your estimate differs, check the input amount first. Then check the rate schedule, additions, relief, burden cap, and whether you are viewing half of an annual housing bill.
