On 8 October 2026, Thailand's Revenue Department issued press release No. 2/2570 (ปชส.2/2570), announcing that together with the Department of Special Investigation, the Department of Business Development, the Anti-Money Laundering Office and other agencies, it had simultaneously raided three target locations in Bangkok linked to groups of juristic persons held by "foreigners who obtained Thai nationality through naturalisation". About 600 companies have been initially identified as at risk of tax underpayment. The department also restated the criminal penalties for tax evasion and the consequences for licence renewal.
1. Eight Agencies Acting at Once
The operation was carried out by the Revenue Department together with the Department of Special Investigation (DSI), the Department of Business Development (DBD), the Department of Employment, the Immigration Bureau, the Department of Lands, the Anti-Money Laundering Office (AMLO) and a special police unit, with simultaneous raids at three target locations in Bangkok. The press release was issued on behalf of the Director-General by Ms Salakjit Pongsirichan, Revenue Strategy Advisor (financial and banking transactions).
The combination of agencies itself shows the dimensions being checked: the DBD covers company registration and shareholding, the Department of Employment covers work permits, the Immigration Bureau covers visas and residence, the Department of Lands covers property holdings, AMLO covers money flows, and the Revenue Department covers filings and tax. Arrangements that look fine from a single angle are exposed when the data is cross-checked.
2. About 600 Companies on the Review List
The Revenue Department said it had initially identified about 600 companies at risk of tax underpayment, whose conduct may affect the country's economic and social security and involve tax evasion.
It is important to read this number correctly: 600 is the scope of review, meaning companies placed under further examination. It does not mean 600 companies have been found to have broken the law. The press release speaks of a "risk of underpaid tax"; no findings have been published.
The press release did not disclose the amounts of tax involved.
3. Penalties and Knock-On Consequences
The press release cites two layers of consequences.
The first is administrative and licensing: failing to file and pay tax is unlawful and may affect the renewal of licences to operate in Thailand. For companies that depend on a Foreign Business License (FBL), BOI privileges or sector-specific licences, this layer often hurts more than the tax itself.
The second is criminal: wilful tax evasion is a criminal offence punishable by 3 months to 7 years' imprisonment and a fine of THB 2,000 to 200,000 (Section 37 of the Revenue Code) (about RMB 440 to 44,000).
The department also published its tip-off channels, hotline 1161 and www.rd.go.th, and promised to protect informants' identities and act promptly.
4. Compliance Lessons for Chinese Companies in Thailand
This operation targets "groups of juristic persons held by naturalised Thai individuals", not companies of any particular nationality. But its review logic applies to every company with foreign backing, and suggests three areas for self-checking.
First, genuine shareholding and source of capital. The core capability of cross-agency matching is to look at shareholder identity, capital contribution records, money flows and business substance together. Whether the local shareholders on the register actually contributed capital, take part in decisions and really receive dividends may not stand out to a single agency, but it is a focus in a joint review.
Second, complete filings and consistent books. Underpayment risk is usually triggered not by applying the wrong rate, but by income not fully recorded, related-party transactions not priced at market value, or non-compliant cost invoices leading to disallowed deductions.
Third, the link between licence renewal and compliance records. Since tax violations can affect licence renewal, companies approaching an FBL, BOI or sector licence renewal should check in advance that their tax filing record is complete, with no outstanding tax or unfiled periods.
Key Takeaways
On 8 October 2026 Thailand's Revenue Department and seven other agencies simultaneously raided three Bangkok locations linked to groups of juristic persons held by naturalised Thai nationals.
About 600 companies were initially flagged as at risk of tax underpayment. This is the scope of review, not a finding of violation; no conclusions have been published.
The department stated that failing to file and pay tax may affect the renewal of licences to operate in Thailand, a consequence beyond the tax itself.
Wilful tax evasion is a criminal offence punishable by 3 months to 7 years' imprisonment and a fine of THB 2,000 to 200,000 (about RMB 440 to 44,000).
Cross-agency matching looks at shareholding, capital, visas, work permits, property, money flows and tax filings together; being "compliant" from one agency's view no longer means being compliant overall.
Z&X Tip
The signal from this operation is that cross-agency data matching is already running in practice. We recommend that companies first check three things: whether shareholders' capital contributions are backed by real records and payment evidence, whether related-party pricing is supported by contemporaneous documentation, and whether any unfiled periods exist ahead of a licence renewal. The seven modules of the Z&X Annual Finance & Tax Advisory Retainer include "Government Supervision and Audit Response" and "Cross-Border Transactions and Pricing"; changes to shareholding and registered information are handled through the amendment services of Company Registration & Approval. Whether a specific case constitutes a violation is subject to the determination of the competent authority.
