Mobile number verification on iTax is the process of confirming and authenticating the phone number registered on a taxpayer’s iTax account with the Kenya Revenue Authority (KRA). This verification is done through a One-Time Password (OTP) sent via SMS to the registered mobile number. Once the OTP is correctly entered on the iTax, the system confirms that the mobile number belongs to the taxpayer and is active. This helps KRA maintain accurate taxpayer contact details and enhances the security of iTax.

A verified mobile number is mandatory to fully access and use iTax functionalities. Critical actions such as logging in, filing returns, updating taxpayer details, applying for services and receiving system notifications all rely on OTPs sent to the registered phone number. Without mobile number verification, access to these services may be restricted, making it essential for taxpayers to verify their mobile number to ensure uninterrupted use of the iTax portal.
