The Kenya Revenue Authority (KRA) has rolled out a new digital system designed to automatically spot inconsistencies and fraudulent tax declarations. The move, which forms part of KRA’s broader plan to harness artificial intelligence (AI), aims to close revenue loopholes and bring more Kenyans into the tax net.
Starting January, the automated validation process will be embedded within the iTax platform to flag discrepancies in income statements, VAT claims, and withholding tax data. The system will cross-check these details with third-party information in real time, enabling instant verification of tax filings.
In a statement released on Friday, KRA confirmed that from 10 January 2026, the system will begin validating both individual and corporate tax returns against several data points, including TIMS/eTIMS invoices, withholding tax records, and customs import entries.
“All declared income and expenses must be backed by valid electronic tax invoices that correctly include the buyer’s PIN, except in cases provided for under Section 23A of the Tax Procedures Act, Cap 469B, and the 2024 Electronic Tax Invoice Regulations,” the notice read.
The project forms part of the government’s larger digital reform strategy aimed at enhancing efficiency, transparency, and voluntary compliance.
President William Ruto’s economic adviser, Dr David Ndii, recently revealed that the government is building algorithm-based systems to automate tax assessment and strengthen revenue collection. He explained that the new platform uses machine learning to cross-analyse data from banks, employers, suppliers, and government agencies to detect under-reporting or duplicate claims before refunds are approved.
Ndii added that the transformation aligns with the administration’s fiscal ambition to increase Kenya’s tax-to-GDP ratio from the current 14 per cent to 22 per cent within seven years. “Within a year or two, most of our taxes will be collected by algorithms, not people. We don’t need to squeeze small taxpayers the old-fashioned way, the system will do it passively,” he told NTV.

He also noted that the system borrows concepts from existing digital models such as the Hustler Fund’s credit scoring mechanism and the Social Health Authority’s premium assessment tool. “We already use a machine learning model for premium calculations and another for credit scoring under Hustler Fund. Now we’re developing one for tax assessment,” he said.
According to Ndii, automation will help identify millions of high-earning professionals operating outside formal payrolls. “We estimate there are about 2.5 million taxpayers earning the same as salaried workers but who remain outside the tax net, doctors, consultants, and others in private practice,” he said.
Under the new model, every tax return will be verified against eTIMS invoices, withholding tax certificates, and customs data. Any mismatch between these digital records and the declared figures could trigger audits, delays, or outright rejection of returns.
Tax experts have warned that informal and small-scale businesses might face challenges adapting due to limited access to digital accounting tools. Without properly transmitted eTIMS invoices or matching income data, their filings could be flagged for review.
KRA maintains that the initiative will tighten compliance and curb tax evasion by ensuring every claim is backed by verifiable data.
What the validation means for taxpayers:
-
Organise your eTIMS invoices: Every expense claimed must be supported by a valid eTIMS invoice. Businesses should insist that all suppliers issue eTIMS receipts showing the buyer’s PIN. Manual receipts will no longer be accepted.
-
Check your Withholding Tax data: Ensure your WHT certificates match the income you’ve declared in iTax. Remember, the 5% WHT is a prepayment, not a final tax.
-
Confirm import records: Importers must ensure their declared figures match Customs data in the Integrated Customs Management System (ICMS) and that these align with eTIMS and accounting records.
-
Prepare for audits if data conflicts: Inconsistencies between returns and digital records could delay refunds or prompt audits.
-
Start early: Taxpayers, particularly small traders, should begin digitising their 2025 records, reconcile invoices, and seek help from KRA or qualified accountants ahead of the next filing season.
The message is clear: Kenya’s tax future is digital, and those who keep their books in order will have far less to worry about when the algorithms start watching.
