Frequently Asked Questions

What do we need to provide each month?
Bank statements, sales and purchase invoices, payroll and expense records. Importers also need to supply customs entries. We give you a monthly checklist and you work down it.
Which taxes apply in Thailand?
Corporate income tax, VAT at the standard 7% rate, withholding tax and stamp duty, plus social security registration and filing. Importers also deal with customs duty and VAT deferment. Filings run monthly and annually.
What happens if filings are missed?
Penalties plus surcharges, calculated on the tax owed and how long it is overdue. Repeated irregularities invite a tax audit, and serious cases affect the company's annual renewal and work permit extensions. That is why we recommend clean bookkeeping from the first month.
Can this be handled remotely?
Yes. Scanned vouchers or electronic statements are enough, and we return reports and filing confirmations monthly. Documents requiring signature are couriered in advance or handled by e-signature.
