In Kenya’s constantly changing financial landscape, Money Market Funds (MMFs) remain a go-to investment option for individuals and institutions seeking low-risk, liquid returns.
With yields ranging around 10-12% in recent months amid stabilising interest rates, MMFs offer a compelling alternative to traditional savings accounts.
However, understanding the tax implications is crucial to maximising your net gains.
This 2025 guide breaks down the withholding tax on MMF returns, drawing from the latest Kenya Revenue Authority (KRA) guidelines and recent market insights.
We’ll cover the rates, processes, and key considerations, no changes from prior years, but plenty of practical advice.
What Are MMF Returns and Why Do They Matter?
Money Market Funds pool investor money into short-term, high-quality securities like Treasury bills, commercial paper, and bank deposits. Returns come primarily in the form of interest, accrued daily and often distributed monthly or quarterly. As of August 2025, average MMF yields dipped slightly to about 11.5% due to easing Central Bank Rate pressures, but they still outpace inflation.
Taxation focuses on these interest earnings, treated as passive income under Kenya’s Income Tax Act. Unlike capital gains (which are exempt for MMFs), interest is subject to withholding tax deducted at source by the fund manager.
The 2025 Withholding Tax Rate: Still 15%
Good news for investors: The withholding tax rate on MMF interest remains unchanged at 15% for both residents and non-residents.
This flat rate applies to the gross interest earned and is withheld before crediting your account. For example, if your MMF generates KSh 10,000 in interest, you’ll receive KSh 8,500 net, with KSh 1,500 remitted to KRA.
This rate has held steady since the Finance Act 2018 and was reaffirmed in the Finance Act 2025, which focused on amendments to dividends, housing bonds, and public procurement payments rather than MMF interest.

How Withholding Works: Step-by-Step Guide
- Accrual and Calculation: Interest is calculated daily based on your units held and the fund’s effective annual yield (EAY). Fund managers provide monthly statements showing gross interest.
- Deduction at Source: The Collective Investment Scheme (CIS) manager automatically withholds 15% on distributions. This is a statutory obligation under Section 35 of the Income Tax Act.
- Remittance to KRA: The manager remits the tax to KRA by the 20th of the following month via iTax. You’ll receive a withholding tax certificate automatically for your records.
- Crediting Your Account: Net proceeds hit your MMF account or linked bank, ready for withdrawal or reinvestment.
Non-residents follow the same process, but if you have a double taxation agreement (DTA) with Kenya, you might claim relief; consult KRA or a tax advisor.
Is Withholding Tax Final?
Yes, the 15% withholding is a final tax for MMF returns. You don’t declare it in your annual personal income tax return (IT1) or corporate tax filing.
This simplifies compliance, as the tax is settled at source. However, track your certificates for audits; KRA cross-checks via iTax.
No Major Changes in 2025: What the Finance Act Means for You
The Finance Act 2025, assented to in June, introduced reforms like a 0.5% WHT on goods supplied to public entities and higher per diem thresholds (up to KSh 10,000 tax-free).
But MMF taxation? Untouched. Yields may fluctuate with the 13-week T-bill rate (around 10.8% in September 2025), but the tax bite stays predictable.
Tips for MMF Investors in 2025
- Compare Net Yields: Always look at post-tax returns. Tools from platforms like Ndovu or YouTube calculators can help simulate scenarios.
- Diversify Funds: Top performers like CIC or Sanlam offer competitive rates.Checkk monthly factsheets for fees (typically 1-2%).
- Reinvest Wisely: Net returns can compound; consider tax-efficient strategies like linking to SACCOs.
- Stay Compliant: Update your KRA PIN with your fund manager to avoid delays.
- Watch for Updates: Monitor KRA’s iTax portal or Finance Bill 2026 for potential shifts.
