BANGKOK, THAILAND – Foreigners faced a formal ban on land ownership in Thailand but still built legal rental portfolios by using narrowly defined structures in property law.
The ban that was not absolute
Foreigners were prohibited from owning land directly under the 1954 Land Code, which on paper blocked any direct purchase of plots. In practice, lawmakers had created several channels through which international investors legally controlled property and earned rental income.
Those who understood these structures were able to assemble legally secure portfolios in Thailand. The framework allowed investments in apartments, long-term leases and corporate vehicles, each with specific conditions and risks.
Condominiums: the only route to true freehold
The Condominium Act of 1979 allowed foreigners to buy condominium units directly and fully in their own names. Buyers were entered into the state ownership register and received a Condominium Title Deed, which served as full proof of ownership.
With this document, an owner could live in the unit, sell it, pass it on by inheritance or rent it out. Rental income from such apartments was fully legal and formed the financial backbone of life in Thailand for many expatriates.
The 49 percent cap and the need to check the land register
An individual foreigner could own an entire unit, but all foreigners together were not allowed to hold more than 49 percent of the total floor area of a condominium building. Once that quota was reached, the land office refused any further transfers of ownership to non-Thai buyers.
The limit applied to floor space, not to the number of units, so a single large penthouse could sharply reduce the available foreign quota. For that reason, checking the quota with the competent Land Office was considered an essential first step before signing any purchase contract.
Leasehold instead of purchase: access to houses and land
Those who wanted a detached house or a plot of land typically used leasehold agreements under the Civil and Commercial Code. The maximum lease term was 30 years, and extension options could be agreed but were not legally guaranteed.
During the lease term, the lessee was allowed to sublet the property if the main contract explicitly granted that right. This structure made it possible to generate rental yields over decades without any direct land ownership.
Tor Dor 11: a missing registration that erased rights after three years
Any rental or lease contract with a term of more than three years had to be registered with the relevant Land Office. The official registration document was known as Tor Dor 11, and without it, a lessee lost all legal protection after three years.
If the property changed hands, a new owner could demand that the property be vacated without any compensation if the contract was not properly registered. For the registration, the state charged a fee of one percent of the total rent over the full term, plus a small stamp duty.
Thai limited company as owner: opportunity with a hard limit
A Company Limited registered in Thailand was allowed to acquire land directly in its own name. At least 51 percent of the shares had to be held by Thai nationals, while a foreign investor could own up to 49 percent and, with correct contractual arrangements, exercise business control.
The company then appeared as the official owner and landlord, collected rental income and paid corporate income tax. This construction was fully legal only if the Thai shareholders were genuine partners and not merely nominal owners on paper.
Shelf companies and straw men: risk of total capital loss
The Foreign Business Act strictly prohibited the use of straw men to bypass the land ownership ban. A Thai shareholder had to contribute verifiable own capital and play an active role in the company, rather than acting as a purely formal name on the shareholder list.
If such a sham structure was uncovered, authorities could impose fines, entry bans for the foreign investor and the uncompensated loss of the land. Courts and regulators increasingly tightened controls in this area, and only real business partnerships protected investors from complete losses.
Usufruct: discreet protection for international couples
Thai civil law recognised usufruct, granting a person full rights of use and enjoyment of a property without being the formal owner. This right could be granted for a fixed period or for the lifetime of the beneficiary.
In practice, a Thai landowner could grant usufruct to a foreign partner. Once this right was entered in the land register, the holder could legally rent out the property and keep all proceeds, but registration at the Land Office was essential for the right to be enforceable against third parties.
The FET form: without it, no condo transfer
Foreigners purchasing a condominium had to transfer the purchase price from abroad in foreign currency. For transfers from around 50,000 US dollars equivalent upwards, the receiving Thai bank automatically issued a Foreign Exchange Transaction Form (FET), previously known as Tor Tor 3.
Without this bank document, the land office refused to complete any transfer of ownership. For smaller amounts, a bank confirmation letter could be issued on request and was also accepted, provided the precise purpose of the transfer was correctly stated in the payment order.
Tenancy contracts and consumer protection rules
Rental contracts were recommended in bilingual form, in Thai and English, with the Thai version being decisive in court. A clear agreement protected both sides and precisely allocated responsibilities for repairs and maintenance.
Commercial landlords renting three or more residential units were subject to stricter consumer protection rules. Deposits were capped at a maximum of three months’ rent, and clauses that allowed automatic rent increases without prior notice were invalid, making such provisions unenforceable in disputes.
Income tax on rental earnings
Rental income from Thai property was taxable under Section 40(5) of the Revenue Code. Anyone staying more than 180 days per year in Thailand was treated as tax resident and paid progressive income tax ranging from zero to 35 percent, with a flat 30 percent of gross rental income allowed as an expense deduction.
Non-residents faced a withholding tax of 15 percent on gross rents. In addition, the Land and Building Tax Act imposed an annual property tax on rented residential real estate between 0.02 and 0.10 percent of the official assessed value, which was significantly lower than typical rates in many Western countries.
TM30: the 24-hour reporting duty for every landlord
Section 38 of the Immigration Act required every landlord to report foreign tenants to immigration authorities within 24 hours of their arrival. This procedure, known as TM30, placed the obligation clearly on the landlord rather than on the tenant.
Reporting could be completed via the official online portal or the immigration smartphone app. Failure to report exposed landlords to fines between 800 and 2,000 baht, while missing TM30 records frequently caused serious problems for tenants when extending their visas.
Tax evasion and illegal structures: lasting consequences
The ongoing digitalisation of Thai authorities made concealed rental income increasingly visible. Revenue offices consistently pursued outstanding tax, including penalty interest, and those who hid income committed a criminal offence with serious consequences.
Illegal attempts to circumvent the land ownership ban through straw-man structures under the Foreign Business Act were pursued particularly aggressively. In addition to losing the property, foreign offenders risked long-term entry bans, making transparency a prerequisite for any sustainable investment.
Local property lawyers: essential risk protection
Investors who signed contracts without legal support effectively gambled with their capital. A qualified, locally based property lawyer could verify historical ownership, confirm the legality of all documents and identify risks that non-specialists would overlook.
The cost of thorough legal advice was small compared with the potential damage caused by flawed purchase or lease contracts. Those who understood the rules and obtained professional support were able to invest in Thai real estate profitably and for the long term, securing reliable rental income over many years.
