Found an incorrect calculation or outdated tax rule? Tell us.
Every rate, threshold, and allowance used in the calculator is tracked in the Thai Tax Rules Registry. If a figure looks wrong, out of date, or you have a primary source (Revenue Department document, official announcement) that says otherwise, let us know — include the tax year and, if possible, a link to the source.
Report incorrect tax information →Found a calculator bug?
If the annual tax calculator or monthly withholding estimator produces a result that looks wrong, crashes, or behaves unexpectedly, please report it — include which calculator you were using and the inputs that triggered the issue so it can be reproduced.
