The Kenya Revenue Authority (KRA) has opened a crackdown on small traders who change mobile money paybill and till numbers to evade taxes, signalling a shift in the tax-man’s pursuit of the elusive informal sector.
Acting Commissioner-General Lilian Nyawanda said the authority has detected widespread cases of traders frequently switching payment channels to avoid leaving a consistent transaction trail.
The tactic, she warned, no longer shields the traders from scrutiny in the race to weed out tax evaders.
The KRA has previously sought to integrate its system with those of mobile phone operators’ financial platforms to catch those who do not pay tax on their incomes.
To track the transactions, the KRA is largely relying on the electronic tax invoice management system (eTIMS), where businesses supplied with good and services declare payments made to their suppliers via paybills and tills.
‘We’ve got that feedback (switching paybill and till numbers) and our teams have encountered that even in the field,’ Dr Nyawanda said in an interview, noting that KRA compliance officers have flagged the practice across the country.
The growing use of digital payments – particularly mobile money -has made it easier for the KRA to piece together transaction trails, even where traders attempt to disguise them by constantly changing tills or paybills.
The KRA says its systems track such activity by matching transactions across counterparties, since every mobile money payment involves both a sender and a receiver, creating a dual record that can be reconciled even when one party does not declare the income.
‘It’s very easy to see the transactions. If you’re a trader, there’s what you purchase and there’s what you sell. So your transactions somehow will be captured somewhere,’ Dr Nyawanda said. ‘Even if you change tills or paybills, somehow they’ll be captured because you are trading with someone.’
This implies that if you are a trader purchasing stock from a compliant wholesaler, the supplier will list your mobile money account or PIN as the recipient of the goods when filing returns. The KRA system will then capture the purchase record, and when the trader files a “Nil” return or fails to file, the system will flag the discrepancy between the known stock purchases and the declared sales revenue.
The move comes as the government steps up efforts to widen the tax base amid persistent revenue shortfalls, with focus on the informal sector, which is estimated to account for a significant share of economic activity that remains largely undertaxed.
Small traders have for years exploited gaps in enforcement by operating multiple mobile money tills or paybills, often registered under different names, to fragment their income streams and make it difficult for tax auditors to establish accurate turnover levels.
The crackdown underscores the KRA’s shift towards data-led enforcement, relying on transaction matching and system analytics to identify non-compliant taxpayers rather than traditional audits alone.
The tax authority is increasingly flagging individuals and businesses who are actively transacting, but remain outside the tax net as non-filers or declare little income despite high sales or purchase activity.
‘A transaction is not completed by one party, it has two parties,’ Dr Nyawanda said. ‘One party may file, another one may not. So there’s a way we can track from our own system.’
The authority says it is already sending targeted communication to such traders, notifying them that their transactions have been detected and urging them to regularise their tax status. The enforcement push comes against the backdrop of tightening compliance rules that are raising the stakes for businesses operating outside formal systems.
Under the law, businesses are required to present valid electronic invoices to claim expenses and reduce their taxable income. The absence of such documentation raises the tax burden for compliant firms, even where transactions are legitimate.
Small traders are required to navigate the eTIMS, enabling them to obtain compliant invoices from suppliers to deduct the cost of stock.
Where goods are sourced from suppliers with annual turnover below Sh5 million –who are not required to be on eTIMS — the burden shifts to the buyer, who must generate a buyer-initiated invoice through the KRA’s eCitizen platform to support expense claims.
This adds an extra administrative layer to the transactions, especially in informal supply chains where documentation is limited.
Early this month, the KRA rolled out awareness and sensitisation campaigns in Nairobi’s Eastleigh business hub-a key source of goods for traders countrywide-after identifying gaps in the adoption of eTIMS.
In a statement following a consultative meeting with the Eastleigh Business District Association on April 13, the taxman said many traders struggle to obtain the required invoices because ‘traders in Eastleigh receive cash payments’.
‘One of the big gaps we have seen is in terms of tax awareness,’ Dr Nyawanda said. ‘With deliberate and sustained taxpayer education and sensitisation, we can bring taxpayers on board so that they are aware that if you just paid your fair share of taxes, you don’t need to hide.’
Traders earning Sh5 million or more annually are required to register for Value Added Tax (VAT) at the standard rate of 16 percent, while those with annual sales between Sh1 million and Sh25 million are subject to a 1.5 percent turnover tax on gross sales.
The KRA says the turnover tax, being final, simplifies compliance by focusing on sales rather than profits, which are harder to verify.
The practice of using multiple mobile money tills and paybills has, nonetheless, complicated tax audits, forcing the taxman to rethink its compliance strategies.
‘Yes, it does complicate our work,’ Dr Nyawanda admitted. ‘But what this helps us with is to plan better and focus better and even retweak the approaches that we traditionally used to look for better ways to do things, including continually working on simplified solutions.’
The KRA has sought to allay concerns over data privacy amid increased reliance on digital transaction tracking, saying that existing laws already require businesses to issue eTIMS-compliant invoices and file returns. This, it says, provides legal basis for accessing transaction data.
The authority maintains that it is guided by principles of data governance, including data protection and minimisation, and only gathers the minimum information needed to assess tax obligations.
‘From a tax administration perspective, our interest is to just get minimal data for purposes of tax administration,’ the KRA said. ‘We have no interest in getting trade secrets.’
