Thai Industry Codes at an All-Time High Filer Count, 2026
In short
239 of Thailand's 998 five-digit industry codes now count more active filers than in any prior year, as of 14 August 2026. That is 23.9 percent of every code with a current filing record, the flip side of the 76.1 percent already past their best year. 184 of those 239 codes set a genuinely new record this year rather than just matching an old one. Electricity and gas and arts and entertainment carry the highest share of codes at an all time high, while manufacturing and wholesale and retail hold 106 of the 239 codes in absolute terms.
Which Thai industry codes have more filers right now than ever before?
239 of Thailand's 998 five-digit industry codes with a current 2025 filing record now count more active filers than in any prior year on the books, as of 14 August 2026 (DBD, 2026). That is 23.9 percent of every code still reporting companies, the direct flip side of the 76.1 percent of codes already sitting below their own best year. A closer look at those 239 codes shows most of them are not simply holding steady at an old high. 184 codes, 77.0 percent of the group, pushed past every previous year to set a genuinely new record in 2025. Only 54 codes matched an old peak without beating it, and a single code is too new to have a second year to compare against. Growth among the record setters is real but rarely dramatic, averaging 5.61 percent above each code's own previous best, with the single largest jump reaching 48.0 percent.

Five-digit codes with a complete 2025 filing record, by industry section, ranked by share now at or above their historic peak, as of 14 Aug 2026.
A record high is not the same as a big number
The sections with the highest share of codes at an all time high are small ones. Electricity and gas has only six five-digit codes in total, so four of them being at a peak sounds dramatic but describes a handful of codes, not a wave of new filers. Manufacturing tells the opposite story. Only 21.1 percent of its 369 codes sit at a peak, yet that share still adds up to 78 codes, the single largest count of any section and roughly a third of all 239 codes at an all time high nationwide. Manufacturing and wholesale and retail together hold 106 of the 239 codes, 44.4 percent of the total, simply because those two sections carry so many separate five-digit classifications to begin with. Weighing by filers rather than by codes changes the picture again. The 239 codes at a peak hold 161,710 filers out of 714,157 counted across the whole economy in 2025, a 22.6 percent share, so the majority of active filers still sit in codes that have already passed their best year even as a substantial minority of codes keep setting new highs.
Why a code at an all time high matters
A code hitting a new high is the clearest sign a slice of the Thai economy is still expanding rather than consolidating. The timing lines up with a broader turn the Department of Business Development has reported for 2026. New business registrations rose 2.13 percent in the first half of the year even as total registered capital fell, a pattern consistent with more, smaller ventures forming rather than fewer, larger ones (The Nation Thailand, 2026). That national uptick shows up here as a specific and countable set of industry codes, concentrated in professional services, education, health, and hospitality, that are adding filers rather than losing them. It also sets a useful watchlist. A code that just tied its old peak without beating it, and 54 of the 239 fall into that category, is one to check again next year to see whether it breaks through or slides back.
Definitions
- TSIC code
- The five-digit Thailand Standard Industrial Classification code the Department of Business Development assigns to a company's registered business activity.
- Filer count
- The number of companies that filed a financial statement for a given TSIC code in a given statement year, drawn from the registry's aggregate tables.
- Historic peak
- The highest annual filer count a TSIC code has recorded across every complete statement year in the dataset, 2007 through 2025.
- At an all time high
- A code whose 2025 filer count equals or exceeds every prior year, so 2025 is either a tie with or a new record above its own historic best.
- New record high
- A stricter case of being at an all time high, where the 2025 filer count exceeds every prior year rather than merely matching one.
- Current filing record
- Having at least one company file a financial statement in the most recent complete year, 2025, so the code has a current count to compare against its own peak.
- Statement year
- The fiscal year a filed financial statement covers, recorded in the registry using the Thai Buddhist calendar, which runs 543 years ahead of the Gregorian calendar.
Assumptions
- A code's peak year can fall anywhere from 2007 through 2025, the range of complete statement years in the dataset. Earlier years, 2001 through 2006, exist in the source table but cover too few codes and companies to ever surface as a peak.
- Statement year 2026 is excluded from both the peak search and the current count because registry coverage for that year is still filling in and its filer count is far too low to be comparable.
- A single code has only one year of filing history and is therefore counted as at its own peak by definition. It contributes 1 of the 239 codes but is excluded from the new record versus tied peak split.
- Sitting at an all time high in filer count is a headcount comparison only. It does not by itself indicate rising revenue, profitability, or market health, any of which could move independently of the number of filing companies.
Methodology
Filer counts come from market_tsic_year_insight, which reports the number of companies with a filed financial statement for each five-digit TSIC code in each statement year, drawn from the Department of Business Development registry and refreshed 14 August 2026. A code's historic peak is the highest annual filer count it recorded in any complete statement year from 2007 through 2025. The year 2026 is excluded because registry coverage for it is still filling in and its count is far too low to compare. A code counts as having a current filing record if it reported at least one company in 2025, the most recent complete year, and it counts as at or above its peak when that 2025 count equals or exceeds every prior year. A record setter is a code whose 2025 count strictly exceeds every year before it. Section shares are calculated by joining each five-digit code to its 21-letter industry section.
How we verified this
- 239 plus 759 was recomputed and equals 998, the total count of five-digit codes with a 2025 filing record, so every code is classified as either at or below its own peak with none double counted.
- 239 divided by 998 was recomputed directly and equals 23.9 percent, matching the headline share.
- Within the 239 at-peak codes, 184 plus 54 plus 1 was recomputed and equals 239, splitting into new record highs, ties with an old peak, and a single first-year code with nothing to compare against.
- 184 divided by 239 was recomputed as 77.0 percent and 54 divided by 239 as 22.6 percent.
- The 18 section level counts of codes at an all time high were summed independently, 4+11+11+9+12+9+12+14+2+10+12+78+16+28+7+2+1+1, and total 239, matching the national figure exactly.
- 106 divided by 239 was recomputed for manufacturing plus wholesale and retail combined, 78 plus 28, and equals 44.4 percent.
- 161,710 divided by 714,157 was recomputed directly and equals 22.6 percent, the share of all 2025 filers sitting inside an at-peak code.

Frequently asked questions
How many Thai industry codes have more filers now than ever before?
239 of the 998 five-digit TSIC codes with a current 2025 filing record, 23.9 percent of that group, count more active filers than in any prior year on record.
Are these codes setting new records or just repeating an old high?
184 of the 239 codes, 77.0 percent, strictly exceeded every previous year to set a genuinely new record. The remaining 54 matched an old peak without beating it, and one code is too new to compare.
Which industry sections have the most codes at an all time high?
Electricity and gas and arts and entertainment have the highest share, above 61 percent each, though both are small sections. Manufacturing has the largest absolute count, 78 codes, out of its 369 total.
Do the codes at an all time high represent a large share of all active filers?
No. The 239 codes hold 161,710 filers out of 714,157 counted nationwide in 2025, a 22.6 percent share, so most active filers still sit in codes that have already passed their best year.
