Housing Estates and Land and Building Tax: How Much Do You Have to Pay, How Is It Calculated, and What Homeowners Should Know?

If you asked one hundred homeowners in a housing estate, "Does your house have to pay land and building tax?" you would probably receive three common answers: I don't know, I'm not sure, or I don't think so.

The reality is that it depends on how the property is being used. Some homeowners do not have to pay anything at all, some must pay every year, and others may already be subject to higher tax rates without realizing it. This has become even more important since the Third Amendment to the Land Allocation Act came into effect, providing clearer responsibilities for both homeowners and juristic management organizations.

This article explains which situations apply, who is required to pay, how much tax is payable, what exemptions are available, and the correct payment process.

What Is Land and Building Tax, and Why Does It Matter for Housing Estates?

Previously, Thailand imposed two separate property-related taxes: the House and Land Tax and the Local Development Tax. Because these taxes overlapped and were complicated to calculate, the government replaced them with the Land and Building Tax Act B.E. 2562 (2019), which has been in effect since 2020.

This legislation represented a major tax reform by changing the tax basis from rental income to the property's assessed value and its actual use.

Land and building tax is calculated based on the official appraised value of the property and its usage category, not on rental income or the purchase price. The tax is collected by the local administrative organization (LAO) responsible for the area—such as a municipality, subdistrict administrative organization (SAO), or district office—not by the Revenue Department.

Therefore, if your home is located within a housing estate, the tax notice will be issued by the local authority responsible for that area, not by a central government agency.

Do Homeowners in Housing Estates Have to Pay Land and Building Tax?

The short answer is yes, but it depends on your circumstances. Consider which category applies to you.

Primary Residence

Under the law, a primary residence is a home where the owner's name appears both in the house registration (Tabien Baan) and on the property's title deed. If both conditions are met, the property qualifies as the owner's primary residence.

The benefit is a tax exemption for properties with an appraised value of up to THB 50 million. In simple terms, if the combined appraised value of your house and land does not exceed THB 50 million, you do not have to pay any land and building tax.

Since the appraised value of most homes in typical housing estates is well below THB 50 million, homeowners who have properly registered their residence usually do not have to pay this tax.

Second Homes or Properties Not Used as Your Primary Residence

If you purchased a house but have not transferred your house registration to that address, or if you own multiple houses and have registered your residence at only one of them, the remaining properties are treated as secondary residences.

Secondary residences are not eligible for the primary residence tax exemption and are subject to land and building tax starting from the first baht of taxable value.

Example: A secondary residence with an appraised value of THB 4,500,000 would pay THB 900 in land and building tax per year. Although the amount is relatively small, it must be paid every year.

Rental Properties

This is another area where many people misunderstand the rules. If a house is rented out to someone else, whether on a monthly or annual basis, the law classifies it as commercial use rather than residential use. As a result, the tax rate is significantly higher, generally starting at 0.3%, which is considerably higher than the rate for a secondary residence that is not rented out.

Vacant and Unused Properties

Houses or land left vacant without any beneficial use are subject to the highest land and building tax rates. The tax starts at 0.3%, and if the property remains unused, the rate increases by 0.3% every three years, up to a maximum of 3%.

The taxation of vacant land differs significantly from other property categories because the law is intended to encourage owners to put their land to productive use rather than leaving it idle. In other words, the longer the property remains unused, the higher the tax becomes.

Can You Reduce Your Land and Building Tax?

Yes, it is possible. In fact, many homeowners can reduce their land and building tax without realizing it. Simply taking care of a few basic requirements can immediately lower the amount of tax payable.

1. Register Your Primary Residence

This is the simplest and most effective method. If you have purchased a house but have not yet transferred your house registration to that address, the property will be treated as a secondary residence and become subject to tax. Once you register it as your primary residence, and the appraised value does not exceed THB 50 million, the property qualifies for the tax exemption.

Of course, this benefit can only apply to one residence. If you already live in the property as your main home, there is no reason not to update your house registration.

2. Put Vacant Land to Productive Use

Vacant land and unused properties are subject to the highest tax rates. Simply putting the land to productive use—such as growing vegetables, creating a small garden, or engaging in agricultural activities—may change its tax classification from vacant land to agricultural use.

The difference is significant. Agricultural land is generally taxed from 0.01%, while vacant land starts at 0.3%, making the initial tax rate up to 30 times lower.

3. Verify the Property Classification Recorded by the Local Authority

In some cases, homeowners pay more tax than necessary because the local administrative organization (LAO) has recorded the property's usage incorrectly. For example, a residential property may mistakenly be classified as commercial property.

When you receive your annual tax assessment notice, always verify the property's classification before making payment. If you find an error, you can submit a request for correction within the deadline specified in the notice.

How to Calculate Land and Building Tax Yourself

Calculating land and building tax is much simpler than many people think. The formula is straightforward:

Tax Calculation Formula:

Appraised Property Value × Tax Rate = Annual Land and Building Tax

The appraised value used is the official valuation issued by the Treasury Department, not the property's purchase price or current market value, which is often higher.

Example 1

Mr. Kong owns a detached house in a housing estate. The combined appraised value of the land and house is THB 4,500,000, and his name appears in both the house registration and the title deed.

Since the appraised value is well below the THB 50 million exemption threshold for a primary residence, the entire property qualifies for the exemption.

Land and Building Tax Payable: THB 0

Example 2

Ms. Min owns another house in a housing estate with the same appraised value of THB 4,500,000, but she has not transferred her house registration because she officially resides at another property.

Since this house is treated as a secondary residence, it does not qualify for the exemption.

THB 4,500,000 × 0.02% = THB 900 per year

These examples show that the most important factor is your house registration, not the value of your property. If you have purchased a home but have not yet updated your registration, it may be worth considering whether doing so could reduce your tax liability.

Paying Land and Building Tax: What Do Homeowners Need to Do?

The good news is that homeowners do not need to file a tax return themselves, unlike personal income tax. The entire land and building tax assessment process is handled by the local administrative organization (LAO) responsible for the area. The process works as follows:

Payment Channels: Payment can be made at the local administrative organization's (LAO) office responsible for the area, through participating banks, or via the online payment system provided by some local authorities.

If the Tax Amount Is High: Taxpayers may apply to pay in three installments by submitting a request to the local administrative organization before the payment deadline.

Important: Once you receive your tax assessment notice, you should verify that all information is correct, including both the appraised value and the property's usage classification. If you find any errors, you may submit a request for correction within the deadline stated in the notice.

Paying your land and building tax on time helps you avoid penalties and surcharges.

Who Pays Land and Building Tax for Common Areas in a Housing Estate?

Who Pays Land and Building Tax for Common Areas in a Housing Estate?

What about the roads within the estate, the communal garden, swimming pool, clubhouse, or the juristic management office? Does anyone have to pay land and building tax for these areas?

The answer is yes. The housing estate juristic person is responsible for paying the tax, not the individual homeowners directly. This is because the juristic person is the legal owner or manager of the common areas following the project handover and establishment of the juristic management organization. These assets are typically managed through a housing estate management system.

However, if you ask where the money comes from, the answer is the common area fees paid by homeowners on a monthly or annual basis. In other words, part of the common area fees collected from residents is used to cover the land and building tax for the estate's common areas.

Accounting for Land and Building Tax in Juristic Management

For housing estate juristic management organizations, land and building tax on common areas should be recorded as an operating expense under categories such as utilities or administrative expenses. These expenses should be clearly separated from any costs associated with individual homeowners.

One common issue in many housing estates is that accounting categories are not properly separated, or there is no system to track how much tax each common area property is liable for each year. As a result, when the annual audit takes place, historical records can be difficult to locate.

A good accounting system for housing estate juristic management should support land and building tax recording and integrate these transactions automatically into the income and expense accounting system. Juristic management organizations that still rely on Excel spreadsheets or paper records may consider adopting an accounting package with integrated tax management features. For communities without an in-house accounting team, Silverman's accounting services are also available as an alternative.

For most homeowners whose property is their primary residence, whose house registration has been updated correctly, and whose property's appraised value does not exceed THB 50 million, no land and building tax is payable. However, if you own multiple properties, have not transferred your house registration, or rent out your property, you should review your tax status carefully before each annual payment period.

For housing estate juristic management organizations, land and building tax on common areas is an unavoidable annual expense that must be recorded accurately. Silverman is designed to make this process transparent from the beginning, offering real-time accounting, comprehensive audit records, and a resident mobile application that allows homeowners to view project information, pay bills, and submit maintenance requests anytime and anywhere. Projects using an integrated system like this are less likely to face questions about transparency because the information is already available within the system.
