BOI-Promoted Company Accounting & Tax Privileges 🏛️
iVC 2025
Specialised accounting for companies promoted by the Board of Investment (BOI). Requires segregated bookkeeping of promoted vs. non-promoted revenue, tracking of accumulated CIT exemption utilisation, machinery importation duty waivers (Section 28), and annual Compliance Report filing that determines whether the promotion is preserved or revoked.
Quick answer: BOI-Promoted Company Accounting & Tax Privileges
"บริษัท BOI — บัญชี ภาษี และรักษาสิทธิ์ประโยชน์ · Fees THB 18,000–120,000. Suited to: Companies holding a BOI Certificate of Promotion (Category A1–A5, manufacturing, Cat. 5 & 7) needing bookkeeping, tax exemption tracking, and annual Compliance Report filing to preserve CIT holiday and machinery import waivers."
- 01How is the 8-year CIT exemption actually applied?
- PND. 50 is filed with a BOI schedule showing promoted-income exempt from CIT, non-promoted-income taxed at 20%. Accumulated exempted income is tracked against the CIT-exemption cap set out on your BOI Certificate. Once cap is hit — even before the 8 years elapse — promotion ends.
- 02What is the penalty for missing the Compliance Report?
- BOI issues a written notice giving 60 days to respond. If ignored, the Investment Committee can revoke promotion, backdate CIT liability from Day 1, and demand return of import-duty waivers with penalty. iVC files 30 days early with a reminder system to prevent this.
- 03Do you serve only BOI Tech (A1–A4)?
- No. We serve A1–A4 (Tech/Software/Digital), A5 (IPO/HQ/Regional Trading), Category 5 (Manufacturing), Category 7 (Business Support Services). We do not currently take Agriculture or Mining promotions — those require specialist domain accountants.
- 04Can BOI companies still claim R&D super-deductions?
- Yes. The 200% R&D deduction (Royal Decree 598) is stackable with BOI CIT exemption for the non-promoted portion of income, and can carry forward the excess deduction against future taxable income once CIT holiday expires. Structuring matters — we plan this at the start of the fiscal year.

Frequently asked questions
How is the 8-year CIT exemption actually applied?
PND. 50 is filed with a BOI schedule showing promoted-income exempt from CIT, non-promoted-income taxed at 20%. Accumulated exempted income is tracked against the CIT-exemption cap set out on your BOI Certificate. Once cap is hit — even before the 8 years elapse — promotion ends.

What if we outgrow our promoted scope?
You must file an amendment application with BOI before you commercialise the new scope. Retrospective amendments are rare and costly. iVC advises quarterly whether new activities fit inside the current promotion or need an amendment.
How is my BOI machinery importation tracked?
Via BOI's IC-Online system. Each imported machine is logged against your promoted machinery list and the Section 28 duty waiver is recorded. We reconcile monthly so audits find zero variance.
