Thailand Strongest Five-Year Window for New Companies (2026)
In short
The strongest five-year window for Thai company formation is 2021 to 2025, with 633,863 new registrations as of 17 July 2026. The 2020 to 2024 window sits just behind at 627,673. The 2019 to 2023 stretch, which holds the 2021 record year, ranks only third at 617,300. The best window beats the first one, 2007 to 2011, by a factor of 3.42. The record year sits inside the peak but no longer defines it.
Was 2019 to 2023 the peak? Not quite
Rolling five-year totals from 2007 to 2025 give a clear answer. The peak window is 2021 to 2025, with 633,863 new companies (DBD, 2026). The 2020 to 2024 window follows at 627,673. The 2019 to 2023 stretch lands third at 617,300, which is 16,563 short of the leader. That gap is only 2.7 percent, so the three best windows are close rivals. What separates them is which years they swallow. The 2021 record of 151,205 sits inside all three, and the leader also collects 2024 and 2025 while dropping the softer 2019 and 2020.

New company registrations by five-year founding window, 2007 to 2025, as of 17 Jul 2026.
What the shape says
The first window, 2007 to 2011, produced 185,484 companies. The peak window produced 3.42 times as many. Its lead over 2016 to 2020, at 500,866, is 26.6 percent. Growth was steady for a decade, then the pandemic years bent the curve. In 2021 the register took in 151,205 new companies, 23.5 percent more than the 122,427 of 2020. Then 2022 fell to 119,923, a drop of 20.7 percent. The record year alone makes up 23.8 percent of the peak window. Take it out and every other year in the window still tops 110,000, which is why the plateau is real.
Why this matters
A record year makes a good headline, but a five-year window shows what the economy does when nobody is watching. Roughly 40.6 percent of every company founded since 2007 arrived in the last five full years. Anyone sizing a market for accountants, banks, software or logistics should plan for a register that keeps adding around 125,000 names a year, not the 30,000 of 2007. The caution runs the other way too. Newer cohorts have had less time to close or be struck off, so the recent windows look stronger than an equal count from 2007 would today. Judge the peak as a fact about the registry, not yet as a verdict on business health.
Definitions
- Rolling five-year window
- The sum of new registrations over five consecutive founding years, moved forward one year at a time.
- Founding year
- The calendar year in which a company was registered, in the Gregorian calendar.
- Registry
- The list of registered juristic persons kept by the Department of Business Development.
Assumptions
- Windows overlap, so neighbouring windows share four of five years and are not independent.
- Companies closed before the extract may be missing, which can understate older cohorts.
- Registration counts measure formation, not whether a company trades or files accounts.
- 2026 is incomplete and excluded.
Methodology
Counts are new company registrations by founding year from the Department of Business Development registry, as of 17 July 2026. A five-year window is the sum of five consecutive founding years, giving fifteen windows from 2007 to 2011 through 2021 to 2025. The partial year 2026 is excluded. Figures cover companies still present in the registry extract, so earlier cohorts may be understated by closures.
How we verified this
- Yearly counts 2021 to 2025 were summed: 151,205 + 119,923 + 112,461 + 121,657 + 128,617 = 633,863.
- Yearly counts 2019 to 2023 were summed: 111,284 + 122,427 + 151,205 + 119,923 + 112,461 = 617,300.
- 2020 to 2024 was summed: 122,427 + 151,205 + 119,923 + 112,461 + 121,657 = 627,673.
- Gap between peak and 2019 to 2023: 633,863 - 617,300 = 16,563, which is 2.68 percent of 617,300.
- Peak versus first window: 633,863 / 185,484 = 3.42.
- Total 2007 to 2025 formations are 1,561,866, so the peak window share is 633,863 / 1,561,866 = 40.58 percent.
- 2021 versus 2020: 151,205 / 122,427 - 1 = 23.5 percent. 2022 versus 2021: 119,923 / 151,205 - 1 = -20.7 percent.
- Record year share of the peak window: 151,205 / 633,863 = 23.85 percent. Peak versus 2016 to 2020: 633,863 / 500,866 - 1 = 26.55 percent.
- The registry rows were computed on 2026-07-17, newer than the 2026-07-07 anchor in the data guide, so the newer date is used.
