The Impact of Limiting Tax Loss Carryforward to 5 Years on Kenyan Businesses
The Finance Act 2025, effective July 1, 2025, changes how Kenyan businesses handle tax losses. It limits tax loss carryforward to five years, replacing the previous indefinite carryforward rule. This affects business owners, CFOs, and financial consultants, especially in capital-intensive sectors like energy, manufacturing, and infrastructure. This article explains the new rule, its impact, affected industries, and strategies to manage it, using clear examples and reliable sources.

What Is Tax Loss Carryforward?
Tax loss carryforward lets businesses use past losses to lower future taxable income. This reduces tax payments when profits start. Before 2025, Kenyan businesses could carry losses forward forever. The Finance Act 2025 caps this at five years, meaning losses not used within five years expire.
The New Rule
The Finance Act 2025 restricts tax loss carryforward to five years. After this, unused losses are lost, increasing future tax bills. Businesses can apply for an extension from the Cabinet Secretary of Finance, but approval criteria are unclear. This rule aims to push businesses to become profitable faster but challenges those with long startup phases.
Impact on Businesses
The five-year limit hits capital-intensive businesses hardest. These businesses often lose money early due to big investments. If they don’t profit within five years, they can’t use losses to offset taxes later. This raises their tax burden and hurts cash flow.
For example, a manufacturing company spends KES 100 million on a new factory, losing KES 20 million yearly for six years. Previously, it could use all KES 120 million in losses to reduce future taxes. Now, only KES 100 million from the first five years applies. The KES 20 million from year six is lost, meaning higher taxes when profitable.
Affected Industries
The change impacts industries with long startup periods:
- Energy: Power plants, oil refineries, renewable energy projects.
- Manufacturing: Factories, chemical plants, automobile production.
- Infrastructure: Roads, bridges, ports, airports.
- Real Estate: Large housing or commercial developments.
- Technology: Startups or firms with heavy R&D costs.
These sectors face higher taxes if losses extend beyond five years, affecting project viability.
Industry | Why It’s Affected | Example Impact |
---|---|---|
Energy | High setup costs, long gestation | Power plant loses KES 50M over 6 years; KES 10M unusable |
Manufacturing | Large factory investments | Factory loses KES 20M yearly; final year’s loss expires |
Infrastructure | Multi-year project timelines | Road project loses KES 30M; later losses increase taxes |
Real Estate | Slow development cycles | Housing project loses KES 15M; unused losses raise costs |
Technology | R&D-heavy initial losses | Startup loses KES 10M; tax relief limited |
Mitigation Strategies
Businesses can take steps to reduce the impact:
- Speed Up Profits: Cut costs, improve efficiency, or boost sales to profit within five years.
- Spread Investments: Phase large projects to lower annual losses.
- Diversify Income: Add new products or markets to offset losses faster.
- Plan Finances: Model profitability timelines to align with the five-year limit.
- Seek Extensions: Apply for extensions from the Cabinet Secretary, showing project needs.
- Explore Mergers: Mergers may help use losses, but losses can’t transfer between entities. Get legal advice.
For example, an energy company could phase a power plant’s construction over six years instead of three, reducing yearly losses. A tech startup might launch a side product to generate income sooner.
Conclusion
The Finance Act 2025’s five year tax loss carryforward limit challenges Kenyan businesses, especially in energy, manufacturing, and infrastructure. It may increase tax bills for firms with long loss periods. By speeding up profits, spreading investments, diversifying income, and seeking extensions, businesses can adapt. Consult a tax expert to navigate this change and protect your finances.
