Mining and quarrying files least often, at 43.5 percent, a 35.8 point gap between the two. Electricity and gas companies file at close to double the rate of mining firms.

Which industries file financial statements most and least?
Electricity and gas leads Thailand's 21 industry sections in financial statement filing. 79.3 percent of its 7,833 registered companies have a filed statement on record, as of 17 July 2026 (DBD, 2026). Mining and quarrying sits at the opposite end, with only 43.5 percent of its 8,231 companies filing. That is a 35.8 point gap, and electricity and gas files at close to double mining's rate. Human health and social work runs a close second at 76.2 percent. Construction, the second lowest section with a meaningful company count, files at 57.2 percent. The national average across the 18 ranked sections sits at 63.6 percent. A single national number hides all of this spread.

Why this matters
A single national filing rate of 63.6 percent tells a lender or a policymaker almost nothing about where the gaps sit. Electricity and gas companies operate under utility licensing and regulatory oversight that keeps most of them compliant. Mining and quarrying firms answer to a different regulator and a more concentrated, project based business model, and well over half of them carry no filed statement at all. Wholesale and retail trade is Thailand's largest section by far, with 715,976 registered companies, more than a third of every classified firm in the country. Its 59.3 percent filing rate still sits below the national average, so the sector that shapes the headline economic story is also dragging down overall filing discipline. Anyone building a credit model, a compliance screen or a sector benchmark off registry data needs to know which sections are thin on filings before trusting a ratio calculated from them. Financial statement coverage is not evenly spread across Thailand's economy, and treating it as if it were will misprice exactly the sections that most need a closer look.
Definitions
- Filing rate
- The count of companies in a section with at least one filed financial statement on record, divided by the total registered companies carrying that section's classification.
- Industry section
- One of the 21 lettered ISIC sections the Department of Business Development assigns to a registered company, such as manufacturing or construction.
- Classified industry section
- A registered company that carries one of the 21 lettered section codes. Companies without a section code are excluded from this ranking.
- Companies with data
- Companies whose registry record includes at least one filed financial statement, regardless of which year that statement covers.
Assumptions
- A company counts as a filer if any statement year is on record, not necessarily a recent or annual filing, so the rate reflects filing history rather than current year compliance.
- Public administration, households and extraterritorial organizations are excluded from the ranking and chart because each has fewer than 40 registered companies, though their figures appear in the downloadable data.
- Sections reflect the Department of Business Development's own classification and are not adjusted for companies that changed section over time.
Methodology
Filing rate is the share of registered companies in a TSIC industry section that have at least one filed financial statement on record in the Department of Business Development registry, as of 17 July 2026. It is the count of companies with filed data divided by the total registered companies carrying that section's classification. A company counts as a filer if any statement year is on file, not necessarily the most recent one. Public administration, households and extraterritorial organizations were dropped from the ranking because each has fewer than 40 registered companies, too few to yield a stable percentage, though their raw figures remain in the downloadable data.
How we verified this
- Electricity and gas filing rate recomputed: 6,211 divided by 7,833 equals 79.3 percent, matching the table.
- Mining and quarrying filing rate recomputed: 3,579 divided by 8,231 equals 43.5 percent, matching the table.
- Gap recomputed: 79.3 minus 43.5 equals 35.8 percentage points.
- Ratio recomputed: 79.3 divided by 43.5 equals 1.82, confirming electricity and gas files at close to double mining's rate.
- National average recomputed: summed companies with data, 1,262,719, divided by summed registered companies, 1,986,415, across the 18 ranked sections equals 63.6 percent.
- Wholesale and retail trade share of all classified companies recomputed: 715,976 divided by 1,986,489 equals 36.0 percent, confirming it is more than a third of the total.
- Distance from average recomputed: electricity and gas sits 15.7 points above the 63.6 percent average, 79.3 minus 63.6, and mining and quarrying sits 20.1 points below it, 63.6 minus 43.5.
