Transfer taxes, annual property taxes, rental income tax and the ongoing ownership costs foreign buyers in Thailand routinely miss.

Who pays what is often negotiable, and in some markets it is customary to split transfer taxes between buyer and seller. Establish this in the offer, not at the registry counter — late disputes over a percentage point of a purchase price are entirely avoidable.
There is no broad annual property tax in the Western sense. The Land and Building Tax applies at low rates (roughly 0.02–0.3% of appraised value for residential use, with generous exemptions for a primary home). Rental income is taxable in Thailand and should be declared. On top of tax, budget for building or community maintenance fees, insurance, and a realistic annual maintenance allowance. A useful rule for planning is 1–2% of property value per year in combined running costs — lower for newer apartments with efficient management, higher for standalone houses and pools.
If you let the property, rental income is generally taxable where the property sits, regardless of where you are resident. Keep clean records of gross rent, agency fees, maintenance, and any interest, since deductible expenses materially change the outcome. Double-taxation treaties usually prevent you paying twice on the same income, but they do not remove the obligation to declare it in both places. This is the single most common compliance gap among expat landlords.
Plan the exit before you enter. Ask specifically about capital gains treatment, any withholding applied to non-resident sellers, agency commission on sale, and whether holding period affects the rate. Combined exit friction of 5–8% of sale price is a reasonable planning assumption in most markets. If you own through a company or trust structure, get advice on how the exit will be taxed under that structure before you commit to it at purchase.
Use a local tax adviser for local obligations and a home-country adviser for reporting and treaty questions — the two rarely overlap well, and neither can safely answer for the other. Do this before the purchase completes, because structure decisions are expensive to unwind afterwards.

Get Local AdviceIt helps to sort property costs into three buckets, because they hit at different times and are budgeted for differently. **At purchase.** Budget roughly 3–6% of the purchase price in transaction costs: 2% transfer fee (usually split with the seller), 0.5% stamp duty or 3.3% specific business tax where applicable, plus legal fees of THB 30,000–100,000 for due diligence and contract review. Alongside the taxes and registration items, plan for legal fees, any survey or valuation, currency conversion spread, and the practical cost of making a property habitable. **While you own.** There is no broad annual property tax in the Western sense. The Land and Building Tax applies at low rates (roughly 0.02–0.3% of appraised value for residential use, with generous exemptions for a primary home). Rental income is taxable in Thailand and should be declared. In apartment buildings, service charges are frequently the largest recurring item and are set by the building rather than by you; ask for the last two years of accounts and any planned major works before completion, because approved works can be levied on the current owner. **At sale.** Agency commission, legal fees, any exit or clearance certificates, and capital gains treatment where it applies. Sellers who never modelled the exit are the ones surprised by how much of a paper gain is consumed by costs. Where financing is involved, the arrangement costs belong in the first bucket and the interest in the second: Local mortgages for foreign buyers are limited. A handful of banks lend to foreigners with a Thai work permit and long-term income history; most foreign buyers purchase in cash or finance from their home country. Developer payment plans on off-plan units are widely used.
Two planning rules remove most of the unpleasant surprises. First, judge affordability on the total cost of ownership rather than the purchase price — the annual figure of recurring taxes, charges, insurance and maintenance is what you actually live with. Second, assume you will hold the property long enough for transaction costs to be absorbed; short holding periods are where round-trip costs do the most damage. If the property will be let, the tax position changes shape: rental income is generally taxable where the property sits, allowable deductions differ from what owners expect, and the treatment often depends on whether you are resident. Confirm the position with an adviser qualified in Thailand before you model a net yield, and note that the country where you are tax resident may also have a claim, subject to any double-taxation treaty. Keep the paperwork from day one. Purchase invoices, improvement receipts and evidence of how funds were remitted are what allow costs to be offset later and what a future buyer's lawyer will ask to see. Reconstructing that record years afterwards is expensive and sometimes impossible. Tax rules and rates change, so treat any figure you read — here or anywhere else — as a planning starting point to be confirmed against current official guidance at the time you transact.
Thai transaction costs are assembled from several separate items rather than one purchase tax: a transfer fee calculated on the appraised value, either specific business tax or stamp duty depending on how long the seller has held the property, and a withholding tax on the seller. Who pays which item is negotiable and is frequently split, so it belongs in the price discussion rather than being discovered at the Land Office. Ownership costs work differently from Europe. There is a land and building tax on residential property, but the recurring cost that dominates ownership of a condominium is the common-area fee charged per square metre by the juristic person, plus contributions to the sinking fund for major works. Rental income is taxable in Thailand and non-resident landlords have withholding obligations, so take advice locally before modelling a net figure. Rates and appraised values are revised periodically — verify current figures at the time you transact.
Almost every difficult conversation about Thai property comes back to one issue: what you can hold in your own name. A condominium unit inside the foreign quota is straightforward and registrable to you personally. A house or villa is not, and the two common workarounds — a registered long lease or a Thai company that owns the land — carry very different risk profiles. A registered lease is honest and enforceable, but it is a diminishing asset and renewal beyond the registered term depends on contract rather than statute. A company structure created solely so a foreigner can control land is a nominee arrangement, which is not lawful and can unwind the whole transaction. If a seller or agent presents either route casually, that alone tells you how much independent advice you need. The practical consequence is that resale audiences differ sharply by title type. Foreign-quota condominium units have both local and international buyers; leasehold villas have a much narrower pool, which shows up as time on market rather than as a lower asking price.
Transaction and holding costs in Thailand are one input into two different decisions — whether to buy at all, and whether the yield on a let property survives the deductions. These guides cover both sides.

Yes — rental income is generally taxable in the country where the property is located, and usually needs to be declared in your country of residence too, with treaty relief preventing double taxation.
