Thailand's Micro-Business Economy: 1.5 Million Firms in 2026
In short
Thailand has 1,495,029 micro companies as of 2 July 2026, which is 75.3 percent of all 1,986,709 classified firms. Small firms add another 439,043, so micro and small together reach 97.4 percent of the registry. Medium companies number just 38,827, and only 13,810 firms are large. Three of every four Thai companies are the smallest kind there is.
How large is Thailand's micro-business economy?
It is almost the whole economy. Thailand counts 1,495,029 micro companies as of 2 July 2026, which works out to 75.3 percent of the 1,986,709 firms with a size classification (DBD, 2026). Strip those micro firms away and the small band accounts for a further 439,043 companies, or 22.1 percent of the registry. Together micro and small firms come to 1,934,072, which is 97.4 percent of every classified company in the country. What is left over is thin at the top: 38,827 medium firms at 2.0 percent, and 13,810 large firms at 0.7 percent. Thailand is, before anything else, a nation of very small businesses.

The size distribution in full
| Size band | Companies | Share of classified firms |
|---|---|---|
| Micro | 1,495,029 | 75.3% |
| Small | 439,043 | 22.1% |
| Medium | 38,827 | 2.0% |
| Large | 13,810 | 0.7% |
| All classified | 1,986,709 | 100% |
Company counts and share of the registry by size band, as of 2 Jul 2026.
Why this matters
The shape of this distribution quietly breaks the average. Thailand's reporting companies post average revenue of 61.8 million baht each, a figure that sounds like a mid-size firm. It is not the typical company. That mean is pulled upward by the 13,810 large firms at the top of the registry. Three quarters of all classified companies sit far below it, down in the micro band. A median would tell a very different story than the mean does. The policy read is just as sharp: any measure aimed at the average Thai company is really a measure aimed at a micro business, because 75.3 percent of them are. For wider context, Thailand's micro, small and medium enterprises together produced about 35 percent of national output in 2025 (OSMEP, 2025). The registry counts the firms. It does not make them big.
Definitions
- Micro company
- The smallest enterprise size band in the DBD classification, covering firms below the small-enterprise thresholds for employment and revenue.
- Classified company
- A registered juristic person that carries an assigned enterprise size band. Firms with no size classification are excluded from the base used here.
- Size band
- One of four enterprise categories, micro, small, medium or large, into which each classified company is placed.
- Reporting company
- A registered firm that has filed a financial statement, the subset over which the 61.8 million baht average revenue is computed.
- MSME
- Micro, small and medium enterprise, the combined group of the three smaller size bands used in national SME statistics.
Assumptions
- Each classified company is counted in exactly one size band, so the four bands sum to the classified total.
- Size bands follow the standard DBD thresholds in force on the as-of date and are treated as stable across the registry.
- Firms without a size classification are left out of the base, so shares describe classified companies rather than the entire registry.
- The 61.8 million baht average revenue reflects only firms that filed a financial statement, a smaller group than the full company count.
Methodology
Figures are counts of registered juristic persons in the Department of Business Development registry that carry a size classification, taken as of 2 July 2026. Each company is placed in one band, micro, small, medium or large, following the standard size thresholds applied to registered enterprises. Shares are each band's count divided by the 1,986,709 classified firms and rounded to one decimal. Companies without a size classification are excluded from the base. The 61.8 million baht average revenue is computed over the subset of firms that filed a financial statement, not the full registry.
How we verified this
- Micro share recomputed from raw counts: 1,495,029 / 1,986,709 = 0.7525, which rounds to 75.3 percent, matching the headline.
- Micro-plus-small share recomputed: 1,495,029 plus 439,043 gives 1,934,072, and 1,934,072 / 1,986,709 = 0.9735, which rounds to 97.4 percent.
- Size bands summed for the total: 1,495,029 + 439,043 + 38,827 + 13,810 = 1,986,709, matching the classified-firm base exactly.
- Band shares recomputed and summed: 75.3 + 22.1 + 2.0 + 0.7 = 100.1, consistent with the stated shares under rounding.
