Thailand wants the companies it has courted with tax breaks to put down deeper roots, and to raise capital at home. On 11 September 2026, the Board of Investment approved extra corporate income tax incentives for promoted companies that list on a Thai exchange.
At a glance
- New Economy companies certified by the Stock Exchange of Thailand may receive up to three additional years of corporate income tax exemption, or a 50% reduction for five years.
- Other BOI-promoted companies may receive up to two additional exempt years, or a 50% reduction for three years.
- The incentives apply to listings on the SET, mai or LiVEx. Detailed implementing conditions are to be confirmed.
Three regulators, one pipeline
The BOI to IPO initiative links investment promotion to the capital market. The BOI provides the tax reward. The Securities and Exchange Commission has committed to faster IPO approvals. The Stock Exchange has eased market-capitalisation and track-record requirements for New Economy listings, under rules effective from 11 September 2026. The three bodies formalised their cooperation on 17 September 2026.
Under the revised listing rules, a dedicated special track lets BOI- and EEC-promoted companies list with a one-year operating track record, compared with two years on the general New Economy route.
Qualifying for the listing track and qualifying for the tax holiday are two different tests.
Read the conditions before you count the savings
Being eligible for the special listing track does not of itself confer the extra tax incentive. That requires a separate assessment against the BOI’s implementing conditions, which promoted companies should study closely as they are published.
Large groups also need to do the arithmetic against the global minimum tax. Thailand’s Emergency Decree on Top-up Tax applies to multinational groups with consolidated revenue of at least EUR 750 million. For those groups, additional tax-free years may simply be offset by a top-up tax if the Thai effective rate falls below 15%.
Who should look at this now
- Promoted companies in New Economy sectors, such as digital, electronics, EV and advanced manufacturing, with expansion plans requiring equity capital.
- Founders and investors weighing a Thai listing against an offshore exchange.
- Groups whose existing BOI tax holiday is nearing its end.
What to do now
- Confirm your promoted activity, remaining tax-holiday period and whether SET New Economy certification is realistic.
- Model the incentive against your listing timetable and, for large groups, against Pillar Two top-up tax.
- Watch for the BOI’s implementing announcement before committing to a listing plan built on the incentive.
