KRA announces 2-hour eTIMS outage on Friday night

The Kenya Revenue Authority (KRA) informed that its Electronic Tax Invoice Management System (eTIMS) will experience a two-hour disruption on Friday evening, October 2nd, 2026. This maintenance window, scheduled from 8 pm to 10 pm, will render eTIMS services temporarily unavailable to all users. The authority announced this planned interruption in an official statement posted on its X account.

KRA assured users that all eTIMS services would be down during this period. The tax agency expressed regret for the inconvenience caused and requested users' patience as it endeavors to enhance service delivery. The planned maintenance follows the growing significance of eTIMS in Kenya's tax administration, where businesses are mandated to utilize electronic tax invoices for transactions.

As an integral part of tax validation, eTIMS supports taxpayers through various generation options, such as the eTIMS Online Solution, eTIMS Client, system-to-system integration, and eCitizen services. KRA's system is also employed for validating tax information, with income and expenses declared in tax returns cross-referenced against data sources like TIMS/eTIMS, withholding tax information, and import records.

The current maintenance, however, is not linked to any tax filing deadline or technical failure, but rather described as scheduled maintenance by KRA. This maintenance also follows weeks after KRA and the National Treasury integrated eTIMS with the Integrated Financial Management Information System (IFMIS). Under this new arrangement, suppliers dealing with government entities must generate valid eTIMS invoices before submitting them for payment via IFMIS.

KRA emphasized that invoice details submitted to government entities must match those generated and recorded in eTIMS. The integration aims to facilitate automated validation of tax invoices and strengthen the connection between government payment processes and tax compliance. Businesses relying on eTIMS for invoicing should note that the two-hour maintenance window will render services inaccessible through the affected eTIMS system between 8 pm and 10 pm on Friday. KRA has not extended the maintenance period beyond the stated two hours.
