BOI Post-Approval Compliance
and Reporting Services
After receiving BOI promotion, businesses may have ongoing reporting, compliance and incentive-related obligations. We assist with project reporting, documentation and relevant post-approval submissions. The BOI now requires progress reports on a quarterly basis, within 30 days from the end of the quarter. If reports are not submitted on time, the BOI will suspend the incentives under the promotion certificate.

Free review of your promotion certificate:
what to report and when
Many companies have received a promotion certificate but do not yet have anyone directly responsible for this work. When reports are submitted late or the accounts for the promoted portion are not clearly separated, difficulties also arise in using the tax incentives for that year. Greenpro KSP supports companies holding promotion certificates on a monthly basis: we prepare a compliance calendar based on the conditions in the certificate, set up a system to separate the revenue and expenses of the promoted portion, submit reports through the e-Monitoring system, prepare the information required to apply to use the incentives through e-Tax, and train the company’s accounting department to continue the work.
What Do BOI Post-Approval Services Cover?
Each promotion certificate has its own conditions and deadlines. The main tasks a company must perform can be divided by project phase as follows:

Every quarter, within 30 days from the end of March, June, September and December |

For older promotion certificates that require progress reports in February and July, the BOI has rescinded that condition and now requires quarterly reports instead. If reports are not submitted on time, the BOI will suspend the incentives under the certificate, and if reports are not submitted on 2 consecutive occasions, the incentives may be revoked.
Separating the Accounts of the Promoted (BOI) and Non-Promoted (Non-BOI) Portions
Tax exemptions apply only to profits from the promoted activity, and the company must therefore keep the revenue and expenses of the promoted portion in accounts separate from those of the non-promoted portion. The tax exemption period is counted from the date on which the promoted activity first earns revenue, and dividends paid from the exempted portion of profits likewise need not be included in taxable income throughout that period. Accordingly, the account separation system should be in place from the time revenue begins. If you do not yet have a regular bookkeeper, please refer to Bookkeeping & Accounting Services.
For foreign companies, the Foreign Business Certificate (FBC) obtained after the promotion certificate covers only the activities specified in the certificate. To earn income from other businesses in the Lists annexed to the Foreign Business Act, the company must first apply for a Foreign Business Licence (FBL). For companies that already hold a certificate but have not yet obtained an FBC, please refer to FBC Application Services.

BOI Post-Approval Service Fees and Government Fees
The BOI post-approval service fee starts at 30,000 baht per month, excluding government fees. You may choose ongoing monthly support from our team or engage us for specific tasks on a per-job basis. The price depends on the number of promotion certificates, the volume of machinery and raw materials for which incentives are used, and the work assigned to our team.
Excluding government fees
The machinery system (eMT) and the raw material system (RMTS Online) are provided through the Investor Club Association (IC), which charges registration and service fees at the association’s rates.
Case Example: A Factory That Had Just Received a BOI Promotion Certificate
A factory had just received a promotion certificate but did not yet have a system to separate income from the BOI-promoted portion from general income.
Our team provided monthly support, set up a system to separate revenue and expenses, prepared operating results reports through the e-Monitoring system, applied to use the tax exemption through the BOI’s e-Tax system, and trained the factory’s accounting department.
The factory’s accounting department was able to file P.N.D.50 correctly.
Frequently Asked Questions About BOI Post-Approval Services
In which months must a BOI-promoted company submit reports?
Before commencing operations, you must submit project progress reports through the e-Monitoring system every quarter, within 30 days from the end of March, June, September and December, and an annual operating results report every July. Once permission to commence operations is granted, quarterly reports are no longer required, but the annual results report is still required every July.
What happens if you do not report to the BOI on time?
The BOI will suspend the incentives under the promotion certificate, and if progress reports are not submitted on 2 consecutive occasions, it may consider revoking the incentives. Older certificates that specify February and July reporting cycles must likewise change to quarterly reporting.
What must you prepare when applying to the BOI to commence operations?
You must apply within 36 months from the certificate issue date, enclosing the relevant licences, financial statements certified by the auditor, the asset register, evidence of the date revenue began, and the production process flowchart and machinery layout. Officials then inspect the premises to verify that they match the conditions in the certificate. The certificate of commencement of operations confirms that the investment has been completed as set out in the project. The company may begin earning revenue and use the tax exemption before receiving this certificate.
Must you apply to use the BOI tax exemption every year?
You must apply for every accounting period in which you will use the incentive, through the BOI’s e-Tax system, with the auditor’s opinion, within 120 days from the end of the accounting period, so that the BOI can complete its review in time for you to file P.N.D.50 with the Revenue Department within 150 days.
What if machinery cannot be imported before the deadline?
The right to import machinery is subject to a deadline of 30 months from the certificate issue date. When the deadline arrives, you may apply for an extension through the eMT system 3 times, 1 year each time. The BOI considers the request within 15 business days, unless the promotion certificate specifies that no extension is permitted.
Must you notify the BOI of a change of shareholders or a capital increase?
If the registered capital or the proportion of Thai and foreign shareholding changes, you must first obtain approval to amend the project and then amend the documents attached to the certificate, which the BOI completes within 5 business days once the documents are complete. If foreign shareholding increases, you must attach evidence of the transfer of funds from abroad, and if foreign shareholding reaches 50% in a List Two or List Three activity, you must also apply for an FBC.
How do foreigners apply for visas and work permits through the BOI?
A promoted company first obtains BOI approval for the foreign skilled worker or expert positions, then files for visas and work permits through the BOI Single Window system in accordance with the criteria set by the BOI. The company may submit this filing directly through the system.
Can we engage you for selected tasks only?
Yes. You may engage us for specific tasks on a per-job basis or have our team provide ongoing monthly support, which starts at 30,000 baht per month. You may send us your promotion certificate first so that our team can review which tasks the company must perform, and we will then provide a quotation based on the tasks you select.
