A lot of the foreign buyers we work with aren’t just looking for a place to live — they want a condo that can also earn its keep. The good news is that renting out a Thai condo is completely legal for foreign owners. The part that trips people up is how you rent it out, since Thailand draws a hard line between long-term leasing and short-term, Airbnb-style stays. Here’s what’s actually allowed, what you can expect to earn, and how the tax side works in 2026.
Long-Term Rentals Are Fine — Daily Rentals Almost Never Are
If you hold freehold title to your condo within the building’s foreign ownership quota, you have full rights to lease it out. The catch is the type of rental. Under Thailand’s Hotel Act, any paid stay of under 30 days counts as operating a hotel business, whether it’s a single condo unit or a whole villa — and that applies no matter how the booking was made, Airbnb included. Renting out an individual condo unit night-by-night or week-by-week without a hotel license is illegal, and enforcement has tightened noticeably: the Revenue Department, Immigration Bureau, and Ministry of Interior now cross-reference tax filings, TM30 foreign-guest reports, and booking platform data, and district offices have run undercover bookings to catch unlicensed operators. Penalties can reach up to one year in prison plus fines of THB 20,000 and a further THB 10,000 for every day the violation continues, on top of separate fines of THB 800–2,000 per unreported guest under the TM30 rules.
There’s a narrow legal path for short-term rental through a Certificate of Exemption, but it only applies to properties with 8 rooms or fewer and a maximum of 30 guests at once — built for small guesthouses and villas, not a single condo unit in a high-rise. For nearly every foreign condo owner, the practical and fully legal option is a long-term residential lease — monthly or annual — which falls outside hotel regulation entirely.
What Counts as a Proper Lease
A lease of three years or less only needs to be in writing between you and the tenant; no government filing is required. If you sign a lease for longer than three years, it has to be registered at the local Land Office to be enforceable beyond that three-year mark. Most owners renting to long-term tenants use one-year leases with the option to renew, which keeps things simple and avoids registration altogether.
What Rental Income You Can Realistically Expect
Rental yields vary a lot by city and even by neighborhood, and gross figures always look better than what actually lands in your pocket. As a general guide, gross rental yields in 2026 run roughly 5–6% in Bangkok, 6–8% in Phuket, and 6–7.5% in Pattaya, with smaller units — studios and one-bedrooms — consistently outperforming larger ones, especially outside the most premium central districts. Once you subtract management fees, common area (CAM) charges, routine repairs, and taxes, net yield typically comes in 1.5–2 percentage points lower than the gross figure. A unit advertised as a “7% yield” investment is often closer to 5% once real running costs are factored in, so it’s worth asking any seller or agent for net numbers, not just gross.
How Rental Income Is Taxed
If your tenant is an individual, no tax is withheld when they pay rent — you’re responsible for declaring the income yourself and filing an annual personal income tax return. If your tenant is a registered company, it’s required to withhold 5% at source and remit that to the Revenue Department on your behalf. Non-resident foreign landlords renting through certain arrangements can face withholding of up to 15%, but that isn’t necessarily your final tax bill — it’s a credit against what you actually owe once you file, and any excess is refundable (though refunds aren’t automatic; you have to apply for them).
To file, you’ll need a Thai Tax ID from the Revenue Department. Thailand’s personal income tax is progressive, from 0% on the first THB 150,000 of net taxable income up to 35% above THB 5 million, and you can deduct either a flat 30% of gross rental income with no paperwork, or your actual documented expenses if they run higher. For most single-condo owners, setting up a Thai company to hold the property isn’t worth it — corporate tax plus dividend withholding usually costs more than simply declaring the income personally. If your home country has a tax treaty with Thailand, check whether it offers any relief on double taxation.
Separately from income tax, all condo owners — whether renting the unit out or not — pay an annual Land and Building Tax, typically due in April, at a small fraction of the property’s assessed value. See our Thailand property tax guide for how that’s calculated alongside the transfer taxes you’d have paid on purchase.
Should You Use a Property Management Company?
Self-managing works for owners who live in Thailand or visit often, but most overseas landlords use a property or rental management company to handle tenant screening, rent collection, maintenance, and lease renewals — usually for a percentage of monthly rent. It costs more than doing it yourself, but for an owner living abroad it’s often the difference between a condo that reliably earns and one that sits vacant between tenants or develops maintenance problems nobody catches early.
The Bottom Line
Renting out a condo in Thailand as a foreigner is straightforward and fully legal — as long as you stick to long-term leases rather than short-term, Airbnb-style stays, which carry real legal risk under the tightened 2026 enforcement environment. Go in with realistic net yield expectations rather than headline gross numbers, budget for the tax filing (or a local accountant to handle it), and decide early whether you’ll manage the property yourself or bring in help.
