Basic bookkeeping for a small Thai company (Ltd.) costs 3,000–5,000 THB/month. This includes recording transactions, maintaining ledgers, and preparing monthly financial statements. Companies with more complex operations (multiple revenue streams, inventory, payroll) pay 5,000–8,000 THB/month. Sole proprietorships with minimal transactions can find services from 2,000 THB/month.

Annual corporate tax filing (PND 50/51) costs 5,000–15,000 THB when bundled with bookkeeping. Standalone filing runs 8,000–20,000 THB. Annual financial audits (mandatory for all Thai Ltd. companies) cost 8,000–25,000 THB depending on company size and complexity. The fiscal year ends December 31 for most companies, with filing due within 150 days.

Registering a Thai Ltd. company costs 15,000–35,000 THB through an accounting firm (including government fees of approximately 6,500 THB). The process takes 3–7 business days. You'll need 3 shareholders minimum (can be reduced to 2 after registration), registered capital (typically 2 million THB for work permit purposes), and a registered office address.

Thai tax residents (183+ days/year) must file personal income tax (PND 90/91). Tax rates range from 0% (first 150,000 THB) to 35% (over 5 million THB). Accounting firms charge 3,000–8,000 THB to prepare and file personal returns. Important: since 2024, worldwide income remitted to Thailand in the same tax year is now taxable — consult an expert on structuring.

Pattaya Business Services (PBS) on Second Road caters heavily to expats with English-speaking staff. Sunbelt Asia has an office handling legal and accounting. THT Accounting near Sukhumvit is popular for small companies. Bangkok-based firms like Mazars and KPMG handle larger operations. For personal tax, many expats use Sherrings (Bangkok-based, handles remotely via email).

Companies earning over 1.8 million THB/year must register for VAT (7%). Monthly VAT filing (PP 30) costs 1,000–3,000 THB if handled by your accountant. VAT invoices must follow specific formats — your accountant provides templates. Input VAT (on purchases) offsets output VAT (on sales). Late filing penalties are 1.5% per month on unpaid VAT.

Companies with foreign employees need specific accounting records for work permit renewals — minimum capitalization of 2 million THB per foreign worker and 4 Thai employees per 1 work permit. BOI-promoted companies have special accounting requirements including investment tracking and tax exemption reporting. Specialized BOI accounting costs 5,000–15,000 THB/month.

Thailand has double taxation agreements (DTAs) with 60+ countries. Proper structuring can significantly reduce tax burden. Key considerations: transfer pricing rules for cross-border transactions, withholding tax on dividends (10%) and royalties (15%), and the new worldwide income taxation rules. Consult a tax advisor before structuring — fees of 10,000–50,000 THB for a comprehensive review save much more.

Monthly payroll processing costs 200–500 THB per employee through an accounting firm. This includes salary calculations, social security contributions (5% employer + 5% employee, capped at 750 THB each), withholding tax calculations, and payslip generation. Social security filing (SPS 1-10) is due by the 15th of each month. Provident fund management adds 500–1,000 THB/month.

Employers must register with Social Security within 30 days of hiring. Contributions are 5% each (employer and employee), capped at 750 THB/month per side on a salary ceiling of 15,000 THB. Benefits include healthcare, disability, and retirement. Foreign employees on work permits also contribute. Your accountant handles monthly filings and annual reconciliation.

Verify your accountant holds a valid CPD license from the Thai Federation of Accounting Professions. Look for experience with foreign-owned companies and English communication skills. Red flags: promising unrealistic tax savings, suggesting dual bookkeeping, or not providing regular financial reports. Meet in person at least quarterly — don't rely solely on email/LINE.
