What is a Withholding Tax Certificate?
A withholding tax certificate is a document issued by the payer to the payee to confirm that withholding tax has been deducted as required by law before the payment is made.
This document serves as evidence for the payee and can be used when filing the annual tax return to claim a tax refund or pay additional tax if applicable.
Should the withholding tax rate be 3% or 1%?
