Can Foreigners Rent Out Property in Thailand ?
Yes—foreigners are allowed to rent out property in Thailand, under certain conditions.
However, there are restrictions on land ownership, so most foreigners either:
Buy a condo in their own name (legal if the building is at least 51% Thai-owned)
Buy a villa/house through a Thai company or long-term lease
Once the ownership is in place, renting the property is possible, but the legalities differ based on structure, location, and duration.
Legal Structures for Property Ownership
Here's how most foreigners legally own property in Thailand:
Foreign Freehold (Condo only)
Can rent short or long term
No Thai partner or company needed
Thai Company
You own a villa through a registered Thai company
Must file taxes and maintain compliance as a business
Allows full rental rights if structured properly
Leasehold (up to 30 years renewable)
You lease the land and own the building
You can rent out, but some contracts restrict subletting
⚠️ Beware: Nominee structures (fake Thai shareholders) are illegal and risky
Short-Term vs Long-Term Rental: What’s Allowed ?
Long-Term Rental (30+ days)
✅ Fully legal
✅ No hotel license required
✅ Simple rental agreement suffices
Short-Term Rental (under 30 days)
⚠️ Requires a hotel license or a specific exception under the Hotel Act
⚠️ Illegal if done without proper registration
Despite the popularity of platforms like Airbnb, operating a short-term rental without compliance can lead to fines or closure.
Do You Need a License to Rent Your Villa ?
Yes—if you rent for less than 30 days on a commercial basis, you need a hotel license, unless you qualify for specific exemptions (detailed below).
To get a hotel license, the property must:
Be in a zone where hotels are allowed
Meet fire safety standards
Provide proper parking, sanitation, and access roads
Pass building inspections
Getting a hotel license for a private villa is difficult, time-consuming, and expensive, which is why many owners choose the “less than 4 rooms” exemption.
Hotel Act: When Does It Apply ?
Thailand’s Hotel Act B.E. 2547 applies if:
You rent more than 4 rooms
Or you host more than 20 guests simultaneously
If you're below this threshold, you may apply for a “non-hotel” exemption license, sometimes referred to as a “Ministerial Regulation” license, which is easier and cheaper.
This license is your golden ticket to operate Airbnb-style rentals legally and without risk.
Tourism Registration & Local Approval
Depending on your district and province (like Koh Samui / Surat Thani), you might also need to register with:
The Tourism Authority of Thailand (TAT)
Local municipality or district office
Sanitary inspection authorities (for waste, fire, and water systems)
Your property may also need to undergo environmental and structural inspections, especially if near the beach.
Rental Income Taxation in Thailand
Yes, you must pay taxes on rental income in Thailand—even as a foreigner.
Personal Income Tax (PIT)
Progressive rates from 5% to 35%
You can deduct some expenses
Withholding Tax (if paid via company)
Typically 5% is withheld before payment
VAT
Required if total income exceeds 1.8 million THB/year
If your property is owned by a Thai company, you also need to:
File Corporate Income Tax (CIT)
Submit monthly VAT & Withholding reports
Pay Social Security if you employ staff
Guest Reporting & TM30 Law <a name="tm30"></a>
You are legally required to report each guest’s arrival to Thai immigration using form TM30.
Who must report?
The property owner or manager
How?
Online via immigration.go.th
Or in person at the local Immigration Office
Deadline: within 24 hours of check-in
Penalty: up to 2,000 THB per case
A good property manager will handle TM30 for you automatically.
Rental Agreements & Contracts
Even if you're renting short-term, written rental contracts are highly recommended, both for you and your guests.
Key elements:
Guest name and passport
Check-in / Check-out dates
Security deposit terms
Cancellation and refund policy
Damage clauses
For long-term leases, you should also:
Register the lease with the Land Office (recommended if over 3 years)
Translate the contract to Thai for legal validity
Legal Risks & Common Mistakes to Avoid
Many foreign owners fall into legal traps because they:
Operate short-term rentals without any license
Use illegal nominee Thai companies
Forget to report TM30 or pay taxes
Have unregistered staff (maid, gardener, etc.)
Ignore safety standards (fire extinguishers, emergency exits)
These mistakes can result in:
Fines up to 50,000 THB
Police closure
Immigration blacklist
Loss of rental rights
Don’t risk your investment for a few nights of income.
Why You Need a Property Manager in Thailand
A local property management company can handle the entire legal and operational process for you, including:
✅ Guest communication & check-in
✅ TM30 registration
✅ Tax reporting & accounting
✅ Staff contracts & payments
✅ Emergency response & guest support
✅ Maintenance & cleaning coordination
