Kenya Revenue Authority Links eTIMS and IFMIS to Enforce Strict Government Invoicing Controls

For businesses dealing with government, getting an expense accepted for tax purposes has become as much about the electronic record as the payment itself. The Kenya Revenue Authority, working with the National Treasury, announced the successful integration of the Electronic Tax Invoice Management System with the Integrated Financial Management Information System. This development requires suppliers doing business with government entities to generate valid eTIMS invoices before submitting supplies for payment processing through IFMIS. It also introduces another requirement that could prove just as important for businesses: the details on invoices submitted to government entities must correspond precisely with the invoices generated and recorded in eTIMS.

The announcement comes as the Kenya Revenue Authority continues validating the income and expenses taxpayers declare in their returns against electronic records. The issue became particularly visible during the rollout of income and expense validation for the 2025 Year of Income. A business could incur a genuine expense while dealing with government, such as a business permit or licence, but the government entity involved might not provide an eTIMS invoice. That left the taxpayer with a practical problem. The expense could be real, necessary for the business and supported by other documentation, yet the electronic tax record the Authority wanted to see might not exist.

During a discussion on the new validation regime, Hakamba Wangwe, Chief Manager responsible for eTIMS, acknowledged that government-related transactions presented a challenge. She explained that taxpayers still needed to account for such expenses in their income tax returns, while the Authority was working on a mechanism that would allow taxpayers to input the expenses themselves. She also advised taxpayers to use 2026 to conduct their due diligence and make sure their expenses were properly supported by the end of the year. That advice now reads differently in light of the August announcement as individual transactions are brought under stricter digital oversight.

At the heart of the issue is Section 16(1)(c) of the Income Tax Act, which restricts deductions for expenditure where the transaction invoice has not been generated through an electronic tax invoice management system, subject to applicable statutory exceptions. The tension discussed with Wangwe was whether a taxpayer should lose the ability to claim a legitimate business expense simply because the other party did not provide an electronic tax invoice. That question became more complicated because Section 23 of the Tax Procedures Act places additional record-keeping obligations on commercial entities operating within the jurisdiction.

Why This Matters

The technical bridging of state payment channels and revenue collection infrastructure transforms how commercial entities interact with public sector procurement. By compelling state suppliers to align their billing documentation before payment processing can proceed, tax authorities are effectively shifting compliance verification upstream. This operational adjustment reduces reliance on retrospective audits and forces suppliers to resolve documentation discrepancies at the point of transaction rather than during annual tax filings.

For corporate finance teams, this integration removes the operational ambiguity that previously allowed unsupported expenses to pass through during transitional phases. Because the temporary accommodations granted for the 2025 Year of Income have clear boundaries, businesses must overhaul their internal reconciliation processes. Failure to match procurement records with verified electronic tax invoices risks immediate forfeiture of legitimate deductions under existing statutory provisions.

Opportunities

• Enterprise Integrators: Build automated reconciliation software that matches internal ERP data with eTIMS and IFMIS outputs to prevent invoice discrepancies.
• Tax Advisory Firms: Offer compliance audits targeting government suppliers to ensure internal record-keeping practices satisfy Section 16(1)(c) requirements.
• Corporate Treasuries: Restructure accounts payable workflows to verify electronic tax validation before submitting payment requests for public sector contracts.
