Withholding tax (WHT) remains one of the most litigated areas of Kenyan tax administration. While designed as a collection-at-source mechanism to enhance revenue efficiency, disputes frequently arise at the point of credit recognition, particularly during audits and assessments by the Kenya Revenue Authority (KRA). This article examines how withholding tax credits operate in Kenya, the applicable legal framework, and the practical issues that often lead to disputes.
Under the Income Tax Act (Cap. 470), withholding tax is deducted by the payer from specified payments and remitted to KRA on behalf of the payee. Although remitted by the payer, the tax is legally borne by the recipient of the income. Consequently, withholding tax constitutes a prepayment of income tax and not a separate or additional tax obligation.
Once withholding tax is deducted and properly remitted:
· KRA issues a Withholding Tax Certificate through the iTax system; and
· The deducted amount becomes a tax credit available to the taxpayer.
For non-final withholding taxes—such as those deducted on professional fees, consultancy fees, and management fees—the credit is applied against the taxpayer’s final income tax liability for the relevant period. The effect is to reduce the tax payable or, in some cases, place the taxpayer in a refund position.
Where withholding tax is final, such as certain dividend and interest income, the deduction extinguishes any further tax liability on that income.
In practice, withholding tax credits may only be claimed where:
1. The tax has been properly deducted and remitted to KRA; and
2. The credit reflects in the taxpayer’s iTax ledger.
At the time of filing returns, iTax automatically offsets available credits against the assessed tax. However, where the payer fails to remit the tax, applies an incorrect PIN, or delays filing the WHT return, the credit may not reflect—often giving rise to disputes during audits.
Tax disputes relating to withholding tax credits frequently turn on evidence. The taxpayer bears the burden of demonstrating that:
· The income was subjected to withholding tax; and
· The tax was in fact remitted to KRA.
This position aligns with Section 107(1) of the Evidence Act, which places the burden of proof on the party asserting a fact. The Tax Appeals Tribunal has consistently held that withholding tax certificates are primary evidence of tax paid, but has also recognised that taxpayers should not be unfairly penalised where KRA has already collected the tax.
Nonetheless, the Tribunal has emphasised that documentation alone is not sufficient unless it clearly demonstrates the underlying transaction giving rise to the withheld tax.
From practice, the most common challenges include:
· Claiming credits for tax deducted but not remitted by the payer;
· Mismatched or incorrect PIN details;
· Attempting to claim credits outside the relevant accounting period; and
· Treating withholding tax as an expense rather than a tax prepayment.
Proper contract documentation, reconciliation of iTax ledgers, and timely follow-up with withholding agents are therefore critical.
Withholding tax credits are a central feature of Kenya’s income tax system, intended to prevent double taxation while ensuring efficient tax collection. However, disputes often arise due to administrative failures and evidentiary gaps. A clear understanding of the law, coupled with robust documentation and proactive compliance, is essential for taxpayers seeking to safeguard their entitlement to withholding tax credits.
For taxpayers facing audits or disputes relating to withholding tax credits, early legal and tax advisory intervention can significantly reduce exposure and facilitate effective resolution.
