Revenue Department HQ.

Revenue Department HQ at a glance

The Revenue Department is Thailand's tax authority, and it has become a live question for long-stay foreigners since Thailand changed how foreign-sourced income remitted into the country is treated. Anyone present in Thailand for 180 days or more in a tax year is a Thai tax resident — a threshold many DTV, LTR and retirement-visa holders cross without particularly noticing.

The headquarters at 90 Soi Phaholyothin 7 sets policy and runs the national filing systems. Individual business — registering for a tax identification number, filing in person, asking about your own case — is normally done at the area revenue office covering your registered address, not at headquarters. Bring the same proof of address a landlord gives you for immigration purposes.

Address: 90 Soi Phaholyothin 7, Phaholyothin Road, Phaya Thai, Bangkok 10400
Hours: Mon–Fri on standard Thai civil-service hours; closed weekends and public holidays; the department's call centre is 1161
Nearest station: Ari (BTS Sukhumvit Line) sits at the mouth of Soi Phahonyothin 7 — the headquarters is well inside the soi toward Rama VI Road, so allow a walk or a short ride rather than expecting a station-adjacent building

What's handled here

• Personal and corporate income tax policy and administration
• VAT and specific business tax
• Tax identification numbers and personal income tax filing — handled in practice at the area revenue office covering your registered address
• National e-filing systems and taxpayer guidance

Notable facts

• There is no online self-service route for a foreigner's first tax identification number. The department requires an in-person application at the area office, or one lodged by an authorised representative.
• Tax residency and the treatment of remitted foreign income are not questions a landlord, a letting agent or a relocation coordinator is qualified to answer, and BAANLYY does not give tax advice. Take a Thai tax professional's view on your own circumstances.
• We deliberately publish no rates, brackets or filing deadlines on this page. They change, and the department's own English site is the only version worth relying on.
• The headquarters shares the Soi Ari corridor with the Ministry of Finance and several other ministries, which is why the area is heavily served by government-hour traffic in the morning peak.
