The Definition
In Thailand, the Revenue Code is the main tax law that governs how property-related taxes are assessed, collected, and reported. In real estate transactions, it determines key costs such as withholding tax, specific business tax, stamp duty, and in some cases how a seller’s gains are taxed at transfer. The practical impact is that buyers and sellers must budget for government charges beyond the advertised sale price.
Thailand’s property taxation framework is primarily administered by the Revenue Department under the Revenue Code, while the actual ownership transfer is registered at the Land Office. The Land Office will not complete registration unless the required tax and fee obligations linked to the Revenue Code are addressed, which is why tax planning is a mandatory part of the closing process. Compared with many Western countries, Thailand’s system is highly transaction-driven. Buyers often assume a single closing cost, but Thai transfers involve multiple separate charges (transfer fee, stamp duty, specific business tax, withholding tax). For foreigners, the Revenue Code is not a foreign-only regime, but they often encounter it through condo purchases or lease structures and must navigate compliance steps like foreign fund remittance proof.
Let’s look at a real-world scenario to understand how Revenue Code is applied during a property transaction.
If the Land Office appraised value is THB 5,500,000, the transfer fee (typically 2%) would be THB 110,000. Depending on seller status and holding period, either stamp duty or specific business tax will also apply, alongside any withholding tax due under the Revenue Code.
The Revenue Code directly affects how much cash is needed to close a Thai property deal, and it can change whether a transaction remains profitable. Ignoring it can mean surprise taxes, delayed transfer, or a deal that looks cheap on paper but becomes expensive at the Land Office.
Before signing, ask for a written tax estimate showing transfer fee, withholding tax, stamp duty, and specific business tax side by side, because the cheapest listing price is not always the cheapest closing.
