Use the worksheets with a review process
Each worksheet is a working aid rather than an official filing form. Fill in the company, period, owner and review date; identify missing evidence; and assign follow-up before treating a task as complete. A checked box without a supporting document is not proof that a return was accepted or a liability was paid.
The templates can be opened in your browser, completed locally and printed or saved as PDF using the browser’s print menu. They do not transmit the information you type. Save your completed copy securely before closing or refreshing the page. Do not enter account passwords, full identity documents or unnecessary personal information.
Connect preparation to the appropriate service
The accounting hub explains bookkeeping, tax, payroll, reporting and annual compliance. The company administration hub covers changes to directors, ownership, office, capital and branches. If you are still planning the business, begin with company setup in Thailand.
Employing or relocating foreign staff also requires a separate immigration and work-authorisation review. Use the visa and work permit guides alongside the employment and payroll process. Industry-specific documents and controls are explained in our sector guides.
How to read the official references
The resources link to the Revenue Department, Department of Business Development, Social Security Office and professional accounting sources where relevant. Check the current notice, form, period and filing channel before acting. A general guide cannot determine the treatment of every transaction or replace an authority’s case-specific checklist.
The review date identifies when this edition was checked. A dated calendar example remains an example for that month; it does not promise the same deadlines in later years. If an official portal or requirement changes, use the latest authority instruction and record the source used in your own compliance file.
