Zero Tax, Still Docked KSh 3,693: Payslip Deductions Outrun Kenya's KSh 2,083 PAYE CutZero Tax, Still Docked KSh 3,693: Payslip Deductions Outrun Kenya's KSh 2,083 PAYE Cut

That gap is the story the tax announcements have not told. The figures suggest the proposed cut is real but small, that it reaches only a sliver of Kenya's workforce, and that its cost is large enough to force someone else to pay. Treasury Cabinet Secretary John Mbadi says the Bill goes to Parliament next week, and the design he described on 22 October changes who that someone is.

Mbadi's zero band replaces the KSh 2,400 relief

Today every salaried Kenyan gets a personal relief of KSh 2,400 ($18.49) a month, which cancels the 10% tax on the first KSh 24,000 of taxable pay. Income between KSh 24,000 and KSh 32,333 is taxed at 25%, and pay above that at 30% and higher.

Mbadi wants to swap the relief for a zero rate on the first KSh 32,333. "In fact, we want to do away with this thing called relief," he said on 22 October.

He also gave the reach of the change: of 3,468,997 people in formal employment, 1,328,625 already pay no income tax, and the plan would exempt a further 362,846, according to his figures.

Mwenendo has already argued that the threshold could punish a small pay rise if it works as a hard line. The relief swap raises a different question: what the payslip looks like once everything else is taken out.

The deductions now come before the tax

Since December 2024, health and housing deductions have been taken off pay before income tax is calculated. The Kenya Revenue Authority's notice on the Tax Laws (Amendment) Act, 2024 lists Social Health Insurance Fund contributions, the Affordable Housing Levy and pension contributions as deductible.

That ordering matters. The KSh 32,333 line applies to taxable pay, the amount left after those deductions. On Mwenendo's arithmetic, a worker needs a gross salary of about KSh 36,026 ($277.61) for taxable pay to reach KSh 32,333.

Here is how that payslip breaks down under current rates:

• National Social Security Fund pension contribution at 6%, under the Year 4 rates in force since February 2026: KSh 2,161.56 ($16.66)
• Social Health Insurance Fund at 2.75%: KSh 990.72 ($7.63)
• Affordable Housing Levy at 1.5%: KSh 540.39 ($4.16)
• Income tax after relief: KSh 2,083.35 ($16.05)

Under the proposal the income tax line falls to zero. The other three stay, totalling KSh 3,692.66 ($28.46) a month.

A worker earning exactly KSh 32,333 gross gains less than the headline. After the same deductions, that worker's taxable pay is about KSh 29,019 ($223.62), and current income tax is KSh 1,254.72 ($9.67). That is the full saving, not KSh 2,083.

Three years of rising deductions, one tax cut

Set against recent history, the cut looks smaller still. In 2022, before the housing levy and the health insurance overhaul, a worker on KSh 32,333 paid a flat KSh 900 to the old National Hospital Insurance Fund and KSh 200 to the National Social Security Fund: KSh 1,100 ($8.48) a month.

The same worker now pays KSh 3,314.13 ($25.54) across the three deductions. The rise of KSh 2,214.13 ($17.06) is larger than the KSh 1,254.72 the zero band would hand back.

These are not like-for-like costs. The pension money stays in the worker's own account and the health contribution buys cover. But for a household budgeting on take-home pay, the figures suggest the new tax cut returns a little over half of what deductions added since 2022. Mbadi himself acknowledged the health and housing deductions had cut take-home pay.

The arithmetic forces someone else to pay

A zero band is not targeted. If the first KSh 32,333 of everyone's taxable pay is untaxed and the bands above stay as they are, a bank manager gains the same KSh 2,083.25 a month as a shop supervisor, because both currently pay that amount on the slice between KSh 24,000 and KSh 32,333.

On Mwenendo's arithmetic, the roughly 1.78 million formal workers who would still pay income tax would each gain about KSh 25,000 ($192.65) a year. That comes to about KSh 44.5B ($342.91M) a year before counting the 362,846 newly exempt workers.

That estimate sits close to a figure President William Ruto disclosed in May, when he said some Treasury officials had warned an earlier version of the cut would cost KSh 40B ($308.24M).

That is why accounts of the plan diverge. One account of Mbadi's proposals says earners above KSh 50,000 ($385.30) would pay more, while Mbadi's own remarks have the higher bands staying unchanged. Both cannot hold if the Treasury wants to limit the revenue loss.

Mwenendo's reading is that the cut for low earners will be paid for by higher rates or narrower bands further up the scale. Until the Bill is published, nobody can say where the break-even salary sits.

One worker in 60 gets the new exemption

The reach is narrow. The 362,846 newly exempt workers are about one in ten formal employees. Against Kenya's total employment of 21.6 million in 2025 (a count that leaves out small-scale farming), reported in the Kenya National Bureau of Statistics' Economic Survey 2026, they are about one worker in 60.

Formal jobs number about 3.5 million in the same survey, and more than 87% of the 822,100 jobs added in 2025 were informal. A mama mboga, a boda boda rider or a casual mason pays no income tax to begin with. Their tax comes through value added tax on cooking oil, excise duty on airtime and on mobile money fees, none of which the proposal touches.

The cut, in other words, helps low-paid formal workers, which is a fair aim after the 10% and 25% income tax bands stayed unchanged from January 2021. It does little for the much larger group of Kenyans whose incomes are just as low but who never see a payslip.

As Mwenendo has shown in its look at how inflation and tax erode savings, small gains on paper can vanish once the full set of deductions and price rises is counted.

The Bill will show who funds the KSh 2,083

The Treasury is taking this proposal to Parliament alongside a stamp duty exemption for land deals worth KSh 1M ($7,706) or less. Three numbers in the tabled text will settle what the package means: the new bands above KSh 32,333, the salary at which a worker stops gaining and starts paying more, and the Treasury's own estimate of the annual cost.

Until those are public, the evidence points one way. The zero band is a modest refund on a payslip that has grown heavier for three years, it misses most working Kenyans, and its cost on Mwenendo's arithmetic is too large to come from nowhere. The middle of the pay scale should read the Bill closely, because that is where the bill is most likely to land.
