Complete guide: Accounting, Tax & Payroll for Thai Companies and Expats

Start with status and scope

We collect the company affidavit, accounting period, VAT status, employee records, prior filings and outstanding items. Recurring work is separated from historical remediation before timing is confirmed.

Records for monthly bookkeeping

Core records include purchase and sales tax invoices, receipts, bank statements, payment evidence, contracts and payroll data. Records must reflect real transactions and follow the agreed monthly cut-off.

Assess each tax return separately

VAT, withholding tax, corporate income tax and personal income tax have different tests and forms. The relevant filings depend on the business activity, counterparties and actual transactions.

Link bookkeeping, payroll and social security

Payroll, withholding tax and social-security contributions should use a consistent employee data set so the ledger, tax forms and employment reports can be reconciled.

Financial statements and independent audit

The bookkeeper prepares accounting records and statements; the licensed auditor performs an independent audit. Document delivery and open issues should therefore be planned before year-end closing.

Historical remediation

Missing filings or incomplete books are separated by period, matched to evidence and assessed before correction. Penalties, surcharges and authority decisions remain subject to the relevant agency.

Monthly controls and review

A defined approver, document cut-off, bank reconciliation and open-item list help management identify missing evidence before statutory deadlines.

Official sources to verify

Current forms and duties should be checked against the Revenue Department, Department of Business Development, Federation of Accounting Professions and Social Security Office for the specific matter and date.

Frequently asked questions

What is needed to start bookkeeping?
Start with the company affidavit, accounting period, tax registrations, prior filings, bank records and transaction documents. Additional records depend on the real business.
Can fees be confirmed immediately?
Transaction volume, employee count, VAT status, the existing system and historical backlog should be reviewed before scope and fees are confirmed in writing.
Are the bookkeeper and auditor the same role?
No. The bookkeeper prepares records and statements; the licensed auditor independently examines them where an audit is required.
How do you begin a multi-month backlog?
Records are separated by period, bank balances reconciled and prior filings checked. Higher-risk deadlines are prioritised without inventing figures merely to file quickly.
Must every Thai company register for VAT?
Not solely because it is incorporated. Business activity, revenue, exemptions and current Revenue Department rules must be checked.
What can payroll support include?
Scope may include payroll calculations, withholding-tax data, social-security data and approval reports. The exact deliverables must be stated in the quotation.
Can you guarantee no penalties?
No. Penalties and surcharges depend on facts, deadlines and authority decisions. The team can check completeness and explain identified risks.
Can accounting records be sent online?
Yes, when the business sets a suitable channel, access permissions, approver and document-delivery cycle for its data.

Reviewing tax records and transaction registers before filing
Reviewing payroll, withholding-tax and social-security data
