How does property tax work in Thailand in 2026?

The tax base is the official appraised value the authorities assign to the land, the building, or the registered condominium unit, not the price you paid at the Land Office. Royal Decree rates group property by use: agricultural, residential, other commercial or mixed use, and long-empty assets can sit in higher bands with possible surcharges when land stays unused.

For residential use, published schedules commonly show progressive rates on appraised value, often cited from about 0.02% up to 0.10% depending on whether the home is owner-occupied, rented out, or held as a second property. Qualifying Thai individuals who live in their own registered home may receive exemptions on part of the appraised value when their name appears in the house registration book on 1 January of the tax year. Foreign owners and investors should not assume those Thai-resident exemptions apply to them. Ask the local revenue office for the notice that matches your title and use on the assessment date.

Condominium owners are taxed on the unit's appraised share. That charge is independent of monthly juristic person invoices for lifts and pools, which you budget on condominium fees.

Local offices typically issue an annual assessment notice early in the year, with payment due within the window stated on that notice (commonly around the first half of the calendar year). Pay through the channels on the bill, whether Bangkok's e-payment routes or a provincial treasury counter, and keep receipts with your title file.

If you buy mid-year, confirm with the seller who pays the current year's tax at completion and align the sale agreement with the notice.

Transfer day brings stamp duty, transfer fees, and possibly specific business tax or withholding on a resale. Those are one-time registration charges, not the annual land and building tax. Budget them on property purchase costs, not here.

If you rent the property out, Thailand-source rental profit still falls under personal income tax rules administered by the Revenue Department. Paying the local land and building tax does not replace filing or withholding on rent. Landlords and long-stay owners should read file taxes in Thailand for calendar-year income duties, especially when a Bangkok condo or Phuket villa produces cash rent.

Leasehold villas and company structures do not remove the underlying asset from the tax system. Who holds registered ownership on 1 January drives the notice, which is one reason freehold versus leasehold due diligence matters before you treat a 30-year lease as a full substitute for owner records.
