The Kenya Revenue Authority’s online tax filing portal experienced a system breakdown in the final hours before the June 30 deadline, locking out hundreds of taxpayers who were unable to submit their 2025 income tax returns despite the authority having ruled out any extension.

The iTax platform, which handles filings for more than 22 million registered personal identification number holders, suffered “intermittent delays” and “significant surge in traffic” as millions rushed to beat the midnight deadline.

Some users told The Standard they encountered broken links and error messages when attempting to access the portal, while others reported that the system repeatedly timed out or failed to load after they entered their credentials.
