The land and building tax
Thailand's annual property tax regime is the land and building tax, in force since 2020, which replaced the old household and local development taxes. It is assessed on the government appraised value of the property, not the market price or your purchase price, and appraised values run meaningfully below market in most areas. The tax is collected by the local municipality or district, with bills issued early in the year and payment typically due by April.
Rates depend on how the property is used, and the structure is deliberately gentle on owner-occupiers and residential use, heavier on commercial use, and heaviest on land left idle. Actual ceilings and applied rates have been adjusted repeatedly since introduction, including temporary reductions, so the reliable statement is about the shape rather than the decimal points.
| Use category | Relative burden | Notes |
|---|---|---|
| Owner-occupied residence | Lowest | Substantial exemption thresholds for a primary residence where the owner is on the house registration |
| Other residential use | Low | Second homes and residences held in another's occupation; small fractions of a percent of appraised value |
| Agricultural use | Very low | Generous treatment; the reason city land sprouts banana trees |
| Commercial or other use | Higher | Includes property used for short-term letting run as a business |
| Vacant or unused land | Highest, and escalating | The rate steps up over consecutive years of vacancy to push land into use |
For a foreign owner of a single condo used as a residence, the practical outcome is usually a small annual bill, often trivial relative to the property's value. For holders of vacant land, the escalation over time is real and intentional, and it changes the economics of land banking.
Who pays, and what happens if nobody does
The person liable is whoever owns the property on 1 January of the tax year; for leasehold structures, the registered owner, not the lessee, is liable, though leases frequently pass the cost through contractually, so read yours. Bills are sent to the address on file, which for absentee foreign owners is often the property itself, where they sit unread. Unpaid tax accrues surcharges and, more importantly, surfaces at the worst moment: the Land Office expects taxes to be settled at transfer, so arrears resurface as a last-minute deduction and delay when you sell. The fix is administrative, not financial: have someone collect the bill and pay it every year.
Condo common fees are not tax
Owners sometimes conflate the land and building tax with the monthly common area fee, and they are entirely different obligations. The common fee is a private charge levied by the condominium juristic person, set per square metre per month at rates that scale with the building's positioning, and it funds security, staff, maintenance and the sinking fund. It is typically the far larger annual outgoing: on a luxury Bangkok unit the year's common fees will usually exceed the land and building tax many times over. Unpaid common fees carry their own sting, since the juristic person will refuse the debt-free letter required to register any sale of the unit.
If the property earns rent
Rental income from Thai property is Thai-source income and is taxable in Thailand regardless of where you live or where the tenant pays you. For individual owners it falls under personal income tax at progressive rates up to 35 percent, with a standard deemed expense deduction available for residential lettings, or actual documented expenses if higher. Non-resident owners face withholding on rent paid to them and should file to regularise the position. Two further points deserve attention. First, use matters for the land and building tax: a unit run as short-term accommodation risks classification as commercial use at higher rates, alongside the separate hotel licensing question that short-term letting raises. Second, if you are Thai tax resident, spending 180 days or more in the country, the rental income simply joins your Thai return alongside everything else, a subject our tax residence briefing covers in full.
Owners letting through structures should also keep the paper aligned: the lease registered or stamped where required, invoices issued, and the income declared consistently in Thailand and at home, since treaty relief against double taxation depends on the Thai side being documented.
Appraised values are revised in cycles, and a revision can move your bill without any action on your part. Check the assessment rather than assuming last year's figure.
Keeping it boring
Annual property taxes in Thailand are a solved problem when someone is paying attention: small amounts, fixed deadlines, local offices. For clients, AGP simply folds the property into an annual calendar, collects and settles the bills through our administrators, and keeps the receipts on file so that when a sale eventually comes, the tax history is one thing that never holds up the transfer.
