According to the Controller of Budget report Nairobi City County has once again stamped its dominance in own-source revenue collection, leading all counties with Kshs.13.52 billion in the 2024/25 financial year, according to the Controller of Budget report.

The capital was followed by Narok County at Kshs.5.67 billion, Mombasa at Kshs.5.13 billion, Kiambu at Kshs.5.06 billion, Nakuru at Kshs.3.65 billion, and Kisumu at Kshs.2.46 billion.

Together, the six counties generated more than Kshs.34 billion — over half of the Kshs.67.30 billion collected nationwide.

The strong performance highlights the revenue potential of urban and high-tourism counties, with Nairobi’s bustling economy, Narok’s Maasai Mara tourism, and Mombasa’s port operations driving collections.

The Controller of Budget noted that while some counties underperformed, the leading six are steadily anchoring county governments’ fiscal independence.

Nairobi County recorded a historic 13.5B shillings at the end of the financial year June 2025.

The growth was driven by collections from key hospitals through the Facility Improvement Fund (Kshs.1.398 billion), alongside ordinary revenue streams totaling Kshs.11.79 billion.The growth was driven by collections from key hospitals through the Facility Improvement Fund (Kshs.1.39 billion), alongside ordinary revenue streams totaling Kshs 11.79 billion. Notable was revenue improvement in housing owing to concerted efforts to align revenues from house rents.

“Under the leadership of Governor Sakaja, revenue collection drive has been grounded on ensuring that everyone contributes rather than a few thousands supporting millions.

This has been evident through continued citywide enforcement on land rates, unified business permits (UBP), house rents, and more. This is evident with the Housing department which recorded a significant increase in revenue from house rent collections, reaching KSh 800 million in the 2024/2025 financial year the highest in over a decade.

The Governor in the bid to promote fair taxation further expanded the land rates tax base with an emphasis on rewarding prompt rate payers through ensuring no interests or penalties are applied as opposed to giving waivers to perennial landrates defaulters.

Governor Sakaja has consistently emphasized strengthening own-source revenue collection and expanding development spending to address Nairobi’s infrastructure, health, and social needs.

Considering the county relies solely on own source revenue to fund both its recurrent and development expenditure, with equitable share being fully utilized to fund the counties huge staff personnel emoluments , increased revenue growth and better cash flow management is imperative towards delivering more transformative projects in the coming financial year.
