Understanding Sri Lanka Withholding Tax (WHT / AIT)
Withholding Tax (WHT / AIT) is the statutory tax framework governed by the Inland Revenue Department (IRD) under Inland Revenue Act No. 24 of 2017. Entities making specified payments are required to withhold tax at source before remitting net funds to payees.
Under Year of Assessment 2025/2026 regulations, statutory WHT applies at rates between 5% to 15% depending on the payment classification (Consultancy, Rent, Interest, Royalties, Dividends). Payments for consultancy and rent enjoy a monthly threshold of LKR 100,000.
