Freelance Tax Compliance

Calculating 3% Withholding Tax Before Generating Your QR Code

When invoicing corporate clients in Thailand for service fees above 1,000 THB, corporate payers deduct 3% WHT (50 Tawi). Generating your dynamic PromptPay QR for the exact net amount (Gross - 3% WHT) eliminates reconciliation errors.
