2026 Korea Housing Acquisition Tax Guide: How to Calculate It and First-Time Buyer Discounts

The day I got my loan approved and stamped the contract, my hands were genuinely shaking. The excitement of finally having my own place lasted about five minutes — then I sat down to tally the notary fees and tax receipts and my stomach dropped at the numbers I hadn't budgeted for.

That was acquisition tax. If you focus only on the sale price and don't plan for taxes properly, your budget can fall apart fast. Here's everything I learned the hard way — pounding the pavement and reading tax law — laid out simply: acquisition tax rates by number of homes owned, the surcharge rules for multiple-home owners, and the first-time buyer discount that anyone buying their first home absolutely needs to claim.

Acquisition Tax Rates by Number of Homes and Region

Acquisition tax depends not just on the price of the home at the time of purchase, but also on how many homes you already own and whether the property sits in a regulated (adjustment-target) area or not — and the difference is significant.

As a baseline, owners of a single home pay the standard rate based on the home's value regardless of region, while owners of multiple homes face tiered surcharge rates that vary by region.

Precise Calculation Formula for the 600M-900M KRW Bracket (Single Home)

The standard acquisition tax rate for owners of one home (or temporary two-home owners) is 1% at 600M KRW or below, and 3% above 900M KRW. But for the bracket between 600M and 900M KRW, a formula is applied so the rate scales smoothly from 1.01% to 2.99%, avoiding a sudden jump at the threshold.

The Bracket Calculation Formula

$\text{Acquisition tax rate (\%)} = \left( \text{Purchase price (KRW)} \times \frac{2}{300\text{M KRW}} - 3 \right) \times 1\%$

• Simplified mental-math version: $(\text{Home price (in 100M KRW units)} \times \frac{2}{3} - 3) = \text{Rate (\%)}$
• Example: for a home priced at 750M KRW → $7.5 \times \frac{2}{3} - 3 = 5 - 3 = 2.00\%$

Effective Tax Rate by Price Point

(Note: Homes larger than the National Housing Scale of 85㎡ are also charged a separate 0.2% special rural development tax, regardless of price.)

Multi-Home Surcharge Relief: Key Checkpoints

To keep the real estate market active, the government runs relief programs that ease the acquisition tax surcharge burden on multi-home owners. If you're considering an investment purchase or a temporary move, be sure to check the following.

Surcharge Exemption for a 2nd Home in Non-Regulated Areas

In non-regulated areas, buying a second home still gets the general 1-3% rate instead of the 8% surcharge rate.

Using the Disposal Window for Temporary Two-Home Owners

If you already own a home and become a temporary two-home owner by acquiring a new one, you can still get the general 1-3% rate instead of the surcharge rate — as long as you dispose of the previous home within 3 years of acquiring the new one.

First-Time Homebuyer Discount: Eligibility Conditions

If you're buying your very first home under your own name, you should absolutely claim the first-time buyer acquisition tax discount. If you meet the conditions, you can deduct up to 2,000,000 KRW from your calculated acquisition tax for a regular home, or up to 3,000,000 KRW for a small, low-priced home.

The 4 Core Requirements for the Discount

• No-home-ownership requirement: Neither you nor your spouse may have ever owned a home before, for your entire life (no one in the household may own a home).
• Price requirement: The actual transaction price at the time of purchase must be 1.2 billion KRW or less. (No income limit applies.)
• Actual-residence requirement: You must complete your resident (move-in) registration and actually begin living in the home within 3 months of the acquisition date (the balance payment date).
• Paid-transaction requirement: Only applies to paid transactions such as a sale or pre-sale purchase; free transfers such as inheritance or gifts are excluded.

A Worked Example: Precise Acquisition Tax Calculation

Here's the full tax calculation for a first-time buyer purchasing an 84㎡ apartment in the Seoul metro area for 750M KRW.

Steps in the Calculation

1. Calculate the acquisition tax rate: $(7.5 \times \frac{2}{3} - 3) = \mathbf{2.00\%}$
2. Base acquisition tax: 750M KRW $\times$ 2.00% = 15,000,000 KRW
3. Local education tax: 15,000,000 KRW $\times$ 10% = 1,500,000 KRW
4. Total calculated tax: 16,500,000 KRW
5. Apply the first-time buyer discount: -2,000,000 KRW deduction

Final amount actually payable: 14,500,000 KRW

Frequently Asked Questions and Points to Watch

Q. Can I rent out or sell the home right after receiving the first-time buyer discount?

If you sell, gift, or rent out the home within 3 years of receiving the discount, or fail to move in within 3 months, the entire discounted amount will be clawed back with penalties added.

Q. I once owned a tiny officetel or a small house in the countryside — does that disqualify me from applying as a first-time buyer?

There are exceptions under the tax law that don't count as home ownership, such as owning a single small unit of 20㎡ or less, or acquiring and then disposing of a partial inherited share. However, if a residential officetel was ever counted toward your number of owned homes, you may be excluded, so it's worth checking with your local tax office.
