Siam Legal and The Expansion of the Corporate and Tax Department
Siam Legal and The Expansion of the Corporate and Tax Department
Siam Legal International, our corporate member, a leading full-service law firm in Thailand, is pleased to share an update on the growth of their firm. After 22 years serving businesses and individuals across Thailand, they have expanded their Corporate and Tax Department with the addition of a dedicated Accounting and Compliance Division to meet the rising demand for accounting and compliance support among foreign-owned and internationally managed companies operating here.
As a full-service law firm headquartered in Bangkok, with branch offices in Chiang Mai, Phuket, and Pattaya, they have long advised international clients on Thai law and immigration. This expansion strengthens the capacity to deliver end-to-end tax and accounting services through a team that understands both Thai regulatory requirements and the expectations of overseas business owners. By combining legal, tax, and accounting expertise under one roof, they are able to provide practical solutions that address both compliance obligations and broader business considerations.
Their enhanced department now provides comprehensive monthly accounting, bookkeeping, and tax compliance prepared in accordance with the requirements of the Thai Revenue Department and Thai Financial Reporting Standards (TFRS). Services are designed to help foreign-owned businesses maintain compliance, avoid filing penalties, and keep management informed through clear and timely financial reporting. Services include the preparation and submission of monthly statutory filings, corporate withholding tax (PND 1, 2, 3, 53, and 54), VAT compliance (PP 30 and PP 36), and Social Security Fund registration and reporting. Clients also receive regular management reports — profit and loss statements, balance sheets, trial balances, and general ledgers — to keep their financial position clear and their filings on time.
Recognising that no two companies are alike, they have structured our offering into scalable packages suited to everything from early-stage startups to larger established operations. The aim is straightforward: accurate records, timely filings, and ongoing peace of mind around statutory obligations, supported by multilingual specialists.
For TNCC members establishing or growing a presence in Thailand, their team is glad to discuss your requirements and provide guidance tailored to your objectives.
