Q1 · Thailand Fiscal Quarter

FM1–FM3 · October 2026 – December 2026

What Q1 means in the Thailand fiscal year

Q1 is the opening quarter. Budgets that cleared the previous year-end review are now operative; the focus is on translating planned spend into committed spend without burning down contingency too early. Headcount plans, capex authorisations, and renewed vendor contracts dominate calendar discipline in these three months.
