Running a BOI project, exporting overseas or managing a Thai branch? We handle your bookkeeping and tax filings, keep the right records and explain what your reports mean.
Your business may fit more than one category. We’ll review the activities and records that matter for your accounts.
| Business type | Accounting focus | Records we’ll review |
|---|---|---|
| BOI-promoted company | Project-level income and expenses; promoted / non-promoted activities; incentive conditions. | Promotion certificates, revenue schedules, allocation methods and asset registers. |
| Export business | VAT classification, sales and receipt reconciliation, foreign-currency differences. | Invoices, shipping and customs evidence, customer contracts and bank receipts. |
| Branch office | Local operations, head-office balances, charges and remittances. | Authorised activities, contracts, funding records and inter-office reconciliations. |
| Representative office | Permitted non-revenue activities, head-office funding and local expenses. | Operating scope, funding records, expenditure support and employee records. |
BOI incentives apply to specific projects. If you have several promotion certificates or also earn non-promoted income, your accounts need to show which income and expenses belong to each project.
Our BOI packages include account segregation, cost allocation, material control and BOI progress and annual report support. We can also quote for asset schedules and tax incentive claims.
BOI: corporate income tax incentives guidance ↗BOI promotion does not exempt every transaction or tax. Each project has its own conditions and filing deadlines.
Qualifying exports may attract 0% VAT, which is different from being VAT-exempt. The rules differ for goods and services. Having an overseas customer or invoicing in foreign currency is not enough on its own.
We match sales entries with invoices, shipping or customs documents, customer contracts and payment receipts.
We check tax invoices against your VAT records before filing a return or reviewing a possible refund claim.
We review exchange-rate differences, overseas service payments and transactions with related companies where needed.
We record your branch’s Thai income and expenses and reconcile balances with head office. We also review the tax treatment of inter-office charges and profit remittances.
A representative office carries out permitted non-revenue activities. We track funding from head office, local expenses and payroll, with accounting and tax treatment that reflects how the office operates.
We’ll review your activities and registrations before advising on funding, expenses, income or remittances.
Choose a package based on your monthly transactions. Every package below includes separate BOI and non-BOI accounts, cost allocation and BOI reporting support.

No. Incentives apply to the promoted project and the conditions in its BOI certificate. Your records need to support any exemption you claim. Non-promoted income and other taxes must be reviewed separately.
You’ll need records showing income and expenses for each promoted project, separate from non-promoted activities. Shared-cost calculations, asset records and supporting schedules may also be needed. We’ll review your certificates and activities to confirm the requirements.
No. Qualifying exports may attract 0% VAT, rather than being VAT-exempt. Goods and services have different conditions. Keep invoices, contracts, shipping documents where relevant and payment records to support the treatment used.
