Who Needs This
Airlines (THAI, Bangkok Airways, Thai AirAsia, Nok Air), lessors (AerCap, SMBC Aviation, Avolon), ECAs, financing banks.
Required Documents
- Aircraft lease (ISTAT-style) + engine lease
- IDERA (Irrevocable De-Registration and Export Request Authorisation)
- CoR + CoA
- Bill of Sale + FAA 8050-2 (if US-built)
- Insurance certificate AVN 67B + war risk cover
- Engine Warranty Assignment + Manufacturer's Consent.
Common Pitfalls
- Thailand adopted all Alternative A declarations (self-help 60 days) · airlines must comply or CAAT enforces de-registration.
- Engines are separate from airframes · register independently · pooling agreements need ownership tracking.
- Return conditions (MPD, LLP hours, C-check) missed = multi-million-USD comp claims.
- AVN 67B must endorse lessor as additional insured + contract price hull value + waiver of subrogation.
Typical Use-cases
- LCC · sale-leaseback 6× A320neo · SMBC Aviation Capital · CTC + IR filing + Thai law opinion.
- Cargo airline · 2× 777F operating lease · JOLCO Japanese equity · IDERA registration.
- Regional · 4× ATR 72-600 finance lease · ECA-supported (BpiFrance/SACE).
- MRO dispute · 4-month engine shop overrun · lessor claim USD 2.2M · settled 55%.
FAQ
- What is IDERA?
- Irrevocable POA enabling lessor to de-register at CAAT without airline consent · CTC requires CAAT to honour within 5 business days.
- Operating vs finance lease?
- Operating = 5–12 yr return to lessor · finance = full payout + purchase option · tax + IFRS 16 accounting differ.
- Do I notify engine detach?
- Yes · pooling agreement + monthly report · IR filing if beneficial ownership changes.
- How long for de-registration?
- CTC = 5 business days · non-CTC = 30–180 days · export needs additional CAAT clearance.

Frequently asked questions
- Can a foreigner own 100% of a Thai company?
- Generally no for activities listed in the Foreign Business Act, where majority foreign ownership requires a Foreign Business Licence, a BOI promotion, or treaty rights such as the US–Thailand Treaty of Amity. Manufacturing and certain export activities are largely open, and BOI-promoted activities can permit full foreign ownership together with land-holding and visa privileges, so the right structure depends on the specific activity.
- What is the minimum registered capital for a Thai company?
- There is no general statutory minimum for a Thai-majority company, but practical thresholds apply: THB 2 million of paid-up registered capital per foreign work permit, or THB 1 million if the foreigner is married to a Thai national, and THB 3 million per foreign shareholder for a Foreign Business Licence. Capital should therefore be planned around the visa and work-permit outcome you need, not the incorporation minimum.
- How long does company registration take?
- Registration at the Department of Business Development can be completed within one to three working days once the name reservation, shareholder documents and company objectives are ready, and the VAT registration and social security registration follow afterwards. The realistic end-to-end timeline including bank account opening is two to six weeks, with the bank account usually being the slowest step for foreign directors.
- What ongoing accounting obligations does a Thai company have?
- Every Thai company must keep statutory accounts, file monthly withholding tax (PND 1, 3, 53) and VAT (PP 30) returns by the middle of the following month, file the half-year corporate income tax return (PND 51) and the annual return (PND 50), and have its financial statements audited by a Thai CPA and filed with the DBD each year. Dormant companies are not exempt — nil returns and an audited statement are still required.
