Unpredictable tax rules and unclear assessments are increasing uncertainty for businesses in Kenya, with a World Bank report warning that the way tax policies are implemented may be a bigger concern for firms than the headline tax rates.
In its November 2026 Kenya Economic Update, the World Bank cites a 2022 Business Integrity Market Survey of more than 200 companies, which found that 67 per cent of firms identified ambiguous policies and ad hoc revisions as among the most disruptive integrity challenges.
Another 53 per cent highlighted unclear tax assessments and arbitration involving the Kenya Revenue Authority (KRA), pointing to persistent disputes between businesses and the tax agency.
The findings come despite Kenya having corporate income tax rates broadly comparable to those in neighbouring economies. The report puts Kenya’s corporate income tax rate at 30 per cent, within the 25 to 35 per cent range applied across much of Sub-Saharan Africa.
However, the World Bank says Kenyan firms are more likely than businesses in neighbouring countries to identify taxation as a major or very severe constraint. This suggests that the challenge is not simply how much tax companies are expected to pay, but also how consistently and transparently the rules are applied.
Frequent policy changes and unclear administrative decisions can make it difficult for businesses to forecast their tax liabilities, plan investments and manage cash flows. Firms may also face additional costs when challenging assessments or seeking clarification from tax authorities.
The report identifies the interaction between taxpayers and individual tax officials as another area vulnerable to corruption. Discretion in audits, assessments and the handling of objections can create opportunities for unofficial demands and inconsistent treatment.
These concerns persist as Kenya continues to digitise tax administration. While digital systems can reduce direct contact between taxpayers and officials, the World Bank argues that technology alone will not resolve integrity gaps if decisions remain difficult to track or challenge.
The lender recommends embedding safeguards in tax administration, reducing unnecessary taxpayer-officer interactions and strengthening the monitoring of high-risk functions. It also proposes allowing taxpayers to electronically track the status of refunds, audits, objections and other compliance cases, with clear deadlines and channels for escalating unresolved matters.
The report further calls for transparent and traceable decisions, alongside stronger oversight of tax officials and more effective complaints mechanisms.
For businesses, predictable taxation is essential to investment planning and confidence. The World Bank's findings suggest that improving the credibility and consistency of tax administration will be as important as setting competitive tax rates if Kenya is to encourage private-sector expansion.
