Sri Lanka’s Inland Revenue Department (IRD) has reminded taxpayers to electronically submit their Statement of Estimated Tax Payable (SET) for the Year of Assessment 2025/2026 by August 15, 2025.

The IRD also announced that e-services are now open for filing both the SET and the Return of Income for the Year of Assessment 2024/2025, which must be submitted on or before November 30, 2025.

These deadlines apply to Corporate Income Tax, Partnership Income Tax, and Individual Income Tax, including the IIT Simplified Return. The department cautioned that late payments will incur interest and penalties, and emphasized the importance of using the correct tax type and payment period codes when making payments.
