How Kiambu raised record Ksh6.5B in own-source revenue without new taxes
Fiscal discipline, minimal wastage and commitment by workers saw the Kiambu County government raise a record Ksh 6.5 billion in Own Source Revenue (OSR) over the last year.
The devolved unit’s financial growth rose drastically from Ksh 2.8 billion in 2022 to Ksh 6.5 billion currently, the highest amount realized since the onset of devolution.
Governor Kimani Wamatangi says rather than taxing residents more, his administration committed to streamline revenue collection and close all the gaps through which money is lost, leading to a steady rise in OSR.

Speaking during celebrations to mark four years of his administration on July 22, 2026, at the county headquarters, he projected that in the next three years, the county will be collecting annual revenue in excess of Ksh 11 billion.
“Our target is that within the next three years, God willing, we are going to match a shilling for a shilling for every disbursement to this county and to those who have been watching to see whether the cup will fall, by 2028 this county will raise Ksh 11.5 billion plus and we shall be ensuring services in Kiambu are at the level we want,” Wamatangi stated.
What placed Kiambu County be the best
He pointed out that the growth has placed Kiambu among the leading counties in revenue mobilisation and strengthened its ability to finance development programmes without relying entirely on allocations from the National Treasury.
So far, the Governor noted, the county has built 512 new ECDE centres that rival private academies, 32 new level four and level three hospitals, 26 new markets and thousands of modern stalls.

Besides, at least 12,000 solar streetlights have been installed and over 750,000 farmers supported with farm inputs, while road rehabilitation works have began across the county.
Speaking at the occasion, County Assembly Leader of Majority Geoffrey Mucheke attributed the achievement to Wamatangi’s resilience and focus despite being fought politically by a cross section of Kiambu parliamentarians.
“If we were led by a man who chickens out easily, Kiambu wouldn’t be where it is today. We all know the fights that were directed at the county government started immediately after Wamatangi was elected Governor,” said Mucheke.
Defending the Kiambu gubernatorial seat
Recent utterances by Wamatangi suggest that he may have parted ways with the ruling party and is likely to defend the seat on another vehicle or possibly run independently.
The Governor maintains that he will not be pressured into joining any party, insisting that the people of Kiambu will determine the direction of his political future when the time comes.
“No amount of persecution, blackmail or threats from any quarters will force me into political alignments ahead of the next elections. I will follow the will of the people of Kiambu,” said Wamatangi when addressing riders from Karuri, Kihara, Ndenderu, Cianda and Muchatha wards.
Previously, in June 2025, the Governor’s home was raided by anti-corruption detectives reportedly investigating allegations of “irregular procurement and fictitious payments” to the tune of Ksh 1.5 billion.
However, despite his arrest and day-long questioning by the EACC sleuths who also recovered Ksh 13.6 million in cash from Wamatangi’s residence, no charges were preferred against him.
