VAT affects documentation, accounting and cash flow. Businesses should check their registration status, income categories and document procedures against their actual operations.
Check registration duties and business categories
Different types of revenue may be treated differently. Identify activities subject to VAT, exempt activities and transactions with specific conditions, and consult current information from the Thai Revenue Department.
Documents should reflect actual transactions
Tax invoices, debit notes, credit notes and payment records should contain the required details and be issued at the appropriate time. Sales, accounting and document systems should use consistent data.
- Names and taxpayer identification numbers
- Document dates and reference numbers
- Descriptions of goods or services and tax amounts
- Supporting evidence for corrections or cancellations
Reconcile input and output VAT regularly
Reconcile documents with accounting reports before filing. Review non-creditable input VAT and follow up incomplete records. Regular checks reduce retrospective corrections and reveal potential issues earlier.
When the business model changes Online sales, cross-border services or changes to the corporate structure may affect tax duties. Ask the accounting team and advisers to assess the implications before introducing a new business model.
