About WorkingBee
Last updated 27 October 2026
WorkingBee (Thai: เวิร์คกิ้งบี, called “Nong Pueng” in the chat) is a tax and money assistant on LINE for salaried workers and freelancers in Thailand. Send a slip or receipt to the chat, and it logs your income and expenses, then estimates this year’s Thai personal income tax straight away, so you know whether you owe more or will get a refund well before March.
What it does
- Logs income and expenses from transfer slips and statements
- Estimates personal income tax for types 40(1)–(8), with the allowances you can still use
- Issues quotations, invoices and receipts as PDFs you can send to clients in the chat
- Reminds you of appointments, open tasks and the tax filing deadline
The web calculator is free with no sign-up: try the Thai tax calculator 2026. To start with the assistant in chat, see WorkingBee on LINE.
Names and channels
The service is called WorkingBee and the website is www.workingbee.io. Our LINE and Instagram accounts are spelled with an s, WorkingBees (@workingbees.io), because the original name was already taken. It is the same service.
How reliable are the numbers?
Figures are estimates based on what you enter and the rules the system supports. They are not personal tax advice, so check with the Revenue Department or a professional before filing. See our Terms of Service and Privacy Policy.
