Do You Own the Home on June 1st? Why One Day Can Change Your Tax Bill by Millions of Won
Did you know that where you set the balance date in a real estate deal can shift the tax bill by millions — sometimes tens of millions — of Korean won?
At the center of it all is one seemingly magical date: June 1st. It's the "tax base date" that determines who's on the hook for property tax and comprehensive real estate tax (Korea's holding taxes). Here's a clear breakdown of how a single day's difference in the balance date decides whose tax bill it becomes, along with practical tax-saving tips.

1. The Rule of the June 1st "Tax Base Date": Who Actually Gets Taxed?
Under Korea's Local Tax Act and Comprehensive Real Estate Tax Act, property tax and the comprehensive real estate tax (jongbuse) are both charged for the entire year to whoever is the de facto owner of the home as of June 1st.
The key point here is that the year's tax is not prorated by how many days each party actually owned the property. Instead, whoever owns it at that single moment on June 1st is billed for the entire year's tax.
Who Owes Holding Tax, Based on the Timing of the Sale
| Balance payment date (or registration filing date) | Owner as of June 1st | Who owes that year's holding tax |
|---|---|---|
| Balance paid before May 31st | Buyer | Buyer pays the full amount |
| Balance paid exactly on June 1st | Buyer | Buyer pays the full amount |
| Balance paid on or after June 2nd | Seller | Seller pays the full amount |
💡 Note: The "date of acquiring ownership" used for this determination is whichever comes first: the balance payment date or the date the ownership transfer registration is filed.
2. Negotiation Strategy for Buyers and Sellers on the Balance Date
Once you understand this rule, it becomes clear which balance date works in your favor when buying or selling a home.
1) If you're the buyer
- Goal: It's in your favor to pay the balance after June 1st.
- Strategy: If you set the balance date to June 2nd or later, that year's property tax and comprehensive real estate tax obligation shifts to the seller. Be careful — if you set the balance date to May 31st, you could unfairly end up owing hundreds of thousands (or more) in holding tax you didn't need to pay.
2) If you're the seller
- Goal: It's in your favor to pay the balance or transfer the registration before June 1st.
- Strategy: Set the balance date on or before May 31st (or on June 1st itself) so that year's holding tax shifts to the buyer, letting you close the deal cleanly.

3. Using a Special Contract Clause: "What If the Balance Date Can't Be Adjusted?"
In practice, it's often hard to avoid June 1st because of the buyer's and seller's moving schedules or loan disbursement dates. In that case, the best approach is to add a "holding tax settlement clause" to the contract so both parties can agree cleanly in advance.
📝 Sample Special Clause Wording
"Regardless of the tax base date (June 1st), the 2026 property tax and comprehensive real estate tax on this property will be prorated between the seller and buyer based on their respective periods of ownership, calculated from the balance payment date."
By prorating the holding tax based on the actual balance date through a special clause, you can avoid the unfair situation where one party bears the entire tax bill because of a single day's difference, and keep the deal running smoothly.
4. Frequently Asked Questions (FAQ)
Q1. If I only sign the contract on June 1st but pay the balance in July, who pays the tax?
The contract signing date is irrelevant. What matters is the date the balance is actually paid or the registration is filed. If the balance was paid in July, the owner as of June 1st was the "seller," so the seller must pay that year's tax.
Q2. If the balance is paid exactly on June 1st, who is considered the owner?
Under the Local Tax Act, if the balance is paid or the registration is filed on the June 1st tax base date itself, the buyer is treated as having acquired ownership, and the tax is charged to the buyer. So from a buyer's perspective, it's safest to avoid paying the balance on June 1st itself and push it to June 2nd or later.
