The accounting function needs a keen eye for detail to handle several requirements that should be accounted and paid for on a monthly basis. There’s the preparation, submission, and payment of VAT and withholding tax documents and financial statements that need to be thoroughly reviewed and verified by a licensed accountant.

On top of these tasks, all these documents should be signed and approved by required signatories during the Annual Shareholders’ Meeting within four months upon closing the accounting year, before being sent off to the Revenue Department and the Commercial Registrar within one month to meet compliance requirements and avoid the fine that may amount to 200,000 baht for failure to comply. In addition, there’s a need to be mindful when keeping accounts and company documents, as these have to be kept safely for at least five years at the registered business address of the company.
