Managing Statutory Withholding Tax on Vendor Payments
Under Sri Lankan tax law, companies are legally mandated to deduct Advance Income Tax (AIT) / Withholding Tax (WHT) on specified payments such as rent, technical service fees, and contracts exceeding statutory thresholds.
SyncBooks automates this deduction directly during bill entry. It separates the net payable to the supplier from the WHT liability owed to the IRD, ensuring accounts balance accurately while auto-generating official vendor WHT certificates.
