Why isn’t a tax calculator enough?
Because a calculator answers once — but freelance income lands every month, and every invoice is withheld differently.
Know: pay more, or refund?
Your estimated tax is compared against the withholding already taken across the year — see ahead of filing whether you owe more or can claim a refund, and plan your cash.
Track every 50 ทวิ certificate
Withholding reports by month and by client show exactly who hasn’t sent their certificate yet — how many are missing and how much they’re worth. No more chasing at filing time.
Income and expenses together
Record expenses, check VAT and break-even reports in the same place your invoices live — your tax numbers and your work numbers come from one source.

Frequently asked
Is it really free?
Tax reports (ภ.ง.ด. 90/94), withholding-tax reports, and income/expense tracking are all available on the free plan, with no credit card.
Is the number accurate enough to file with?
It uses the Revenue Department’s progressive brackets plus the deductions you enter, but treat it as a planning estimate — verify with the Revenue Department’s system or an accountant when you actually file, especially if you have several income types.
How is this different from free tax calculators?
A calculator answers once, from numbers you type in. Kitslancer is tied to the real income in your account, updates all year, compares against the actual WHT on each invoice, and tracks missing 50 ทวิ certificates too.
Is my income data safe?
TLS on every request, PDPA-compliant, we never sell your data, and you can export everything at any time. No lock-in.
