The Inland Revenue Department (IRD) said the period for submitting individual income tax returns for the 2025/26 assessment year will open next month, NewsFirst reported, with returns accepted up to November 30, 2026.
The Department said returns can be filed online through the IRD’s official website. It warned that legal action will be taken against taxpayers who fail to submit returns within the stipulated period.
The opening of the 2025/26 assessment-year filing window follows a busy fiscal calendar in which the IRD has been pushed both to broaden the registered taxpayer base and to recover historical arrears. President Anura Kumara Dissanayake met IRD leadership earlier this month on tax broadening and arrears recovery, part of a wider IMF-aligned push to lift recurrent revenue.
The Department has also faced a sustained wave of impersonation scams in recent months, with Sri Lanka CERT and the IRD warning the public against fraudsters using fake tax notices to extort payments. The IRD has consistently advised taxpayers to file directly through its own e-services portal rather than respond to unsolicited contact.
The IRD has not published a specific start date in July or any changes to filing forms for the 2025/26 cycle. Taxpayers earning above the personal relief threshold are required to register and submit returns even where tax has been withheld at source.
