Key takeaways

  • BOI promotion for EV-related manufacturing can include corporate income tax exemptions, import duty relief on machinery, and 100% foreign ownership.
  • Eligibility turns on your exact activity classification — parts, batteries, charging infrastructure, and assembly are treated differently.
  • Apply before you commit capital: incentives are generally not retroactive.

Why the EV push matters for foreign manufacturers

Thailand has set aggressive targets for electric-vehicle production, and the Board of Investment backs them with some of the country’s most generous promotion packages. For manufacturers weighing a move — particularly suppliers following their anchor customers to Thailand — the difference between arriving with and without BOI promotion is measured in years of corporate income tax.

The packages are not one-size-fits-all. Battery cell production sits at the top of the incentive ladder; downstream assembly and conventional parts attract narrower benefits. Before signing a land lease or ordering machinery, have your intended activity mapped against the current eligible-activity list.

What a typical application involves

A BOI application is a business plan exercise as much as a legal one: investment value, employment, technology transfer, and utilization plans all feed the assessment. Approval typically takes several weeks to a few months depending on the activity and investment size, and conditions attach to the promotion certificate — minimum capital, debt-to-equity limits, and reporting duties among them.

FAQ

Can a 100% foreign-owned company get BOI promotion for EV manufacturing?

Yes. BOI promotion is the main lawful route to full foreign ownership of a Thai manufacturing company, overriding the usual Foreign Business Act restrictions for the promoted activity.

We already operate in Thailand. Can we add BOI incentives to an existing plant?

Often yes, through expansion projects or restructuring — but the new investment generally must be genuinely new. This is exactly the situation where early advice pays for itself.
