Kenya’s economy has a deep structural divide: a large, vibrant informal sector that employs the majority of citizens, versus a formal tax system that is rapidly becoming highly digital and sophisticated.

The Kenya Revenue Authority (KRA) is aggressively rolling out tools like eTIMS, automated income and expense validation, real-time invoice tracking and stricter compliance requirements. While these systems are designed to modernise tax administration and widen the tax base, they are creating significant friction for the millions of small and medium enterprises (SMEs) that still operate partly or largely in the informal economy.

This tension is one of the most discussed challenges in Kenyan business circles today. Manufacturers, startups, retailers and small traders consistently highlight the same pain: compliance rules that feel designed for large corporations are being applied to businesses that lack the infrastructure, suppliers or technical capacity to meet them.

This article explores the roots of this disconnect, its real impact on SMEs, and practical ways businesses can navigate the gap between Kenya’s informal reality and formal tax expectations.

The Scale of Kenya’s Informal Economy

Kenya’s informal sector (often called jua kali) is massive. It accounts for:

• Over 80% of employment
• A significant portion of economic activity, especially in retail, manufacturing, agriculture and services
• Millions of small traders, artisans, boda boda operators, and micro-suppliers who operate mainly in cash with minimal record-keeping

Many SMEs sit in the middle ground – partly formal (registered, with a PIN and bank account) but heavily reliant on informal suppliers and cash-based customers. This hybrid model worked reasonably well in the past, but KRA’s digital transformation is making it increasingly difficult to sustain.

KRA’s Formal Tax Vision vs Ground Reality

KRA’s current strategy focuses on:

• Full eTIMS adoption for electronic invoicing
• Automated cross-checking of returns against invoices, withholding data and customs records
• Real-time visibility of transactions
• Stricter Tax Compliance Certificates (TCC) and enforcement

While these tools improve transparency and reduce evasion in the formal sector, they create serious operational challenges for businesses embedded in the informal economy:

1. Supplier Capability Gap Many SMEs source goods from small informal suppliers who are not registered on eTIMS and lack the tools or knowledge to issue compliant electronic invoices. Without valid eTIMS invoices, buyers risk having their expenses disallowed during automated validation – turning legitimate business costs into taxable profit.

2. Limited Understanding of Tax Processes Small traders and micro-suppliers often lack basic knowledge of VAT, proper invoicing or digital record-keeping. Expecting them to instantly comply with complex digital systems creates a supply chain bottleneck.

3. Infrastructure and Technical Barriers Many small businesses operate with unreliable internet, basic phones, limited electricity and no dedicated accounting staff. KRA’s systems assume stable connectivity, modern software and technical capacity that simply does not exist for the majority of SMEs.

4. One-Size-Fits-All Compliance Rules designed for medium and large enterprises are being applied uniformly. A hardware shop in Eastleigh buying from jua kali welders faces the same documentation standards as a large manufacturer with ERP systems.

This mismatch is creating what many business owners call “compliance stress” – where trying to stay legal actually threatens business survival.

The Real Impact on Kenyan SMEs

The tension between informal operations and formal tax rules is producing several negative outcomes:

• Increased Effective Tax Burden: Disallowed expenses push up taxable income, leading to higher tax payments on money that was never profit.
• Cash Flow Pressure: Businesses are forced to either absorb extra costs, chase informal suppliers for proper invoices or switch to more expensive formal suppliers.
• Competitive Imbalance: Informal businesses that ignore compliance entirely sometimes enjoy an unfair price advantage.
• Risk of Penalties and Enforcement: Late or incorrect filings due to supply chain issues can trigger penalties, interest and loss of Tax Compliance Certificates.
• Stifled Growth: Many SMEs deliberately stay small or informal to avoid the heavy compliance burden, limiting job creation and economic formalisation.

In 2026’s already challenging economy – marked by weak demand and tight liquidity – this structural tension is making operations significantly harder for honest business owners trying to do the right thing.

Can the Informal Economy and Formal Tax Systems Co-Exist?

The ideal solution lies in gradual and supportive formalisation rather than sudden, punitive enforcement.

KRA has made some efforts in this direction (extensions, simplified regimes and training programs), but many SMEs feel the pace of digital enforcement is outrunning the reality on the ground.

A balanced approach would include:

• Simplified compliance for micro and small businesses
• More practical support and training for informal suppliers
• Graduated penalties during the transition period
• Better offline and USSD-based solutions for areas with poor internet

Practical Strategies for SMEs to Bridge the Gap

While waiting for policy improvements, forward-thinking businesses are taking these steps:

1. Gradual Supplier Onboarding Identify key suppliers and support them to get onto eTIMS. Offer training, share costs or help with registration. Build a mixed supply chain – formal for high-volume items and informal for low-value ones where possible.

2. Strengthen Internal Controls Maintain excellent internal records even when suppliers cannot provide perfect eTIMS invoices. Keep delivery notes, payment proofs and correspondence as backup documentation.

3. Choose Compliant Tools Wisely Adopt affordable, user-friendly eTIMS solutions that match your business size. Avoid over-investing in complex systems if you’re still small.

4. Leverage Available Simplifications Explore Turnover Tax (TOT) if eligible, as it may reduce some compliance pressure. Use KRA’s daily/weekly payment options where they fit your cash flow.

5. Work with Professionals Engage a reliable tax advisor or accountant who understands both formal requirements and informal realities. Professional guidance helps minimise disallowed expenses and compliance risks.

6. Build Cash Flow Buffers Factor potential disallowed expenses into your pricing and budgeting. Treat compliance as a core business cost rather than an unexpected surprise.

The Road Ahead

Kenya needs its informal sector to thrive and gradually formalise – not through force, but through practical support and realistic timelines. The success of KRA’s digital transformation ultimately depends on how well it serves the millions of businesses operating between the informal and formal worlds.

Business owners who proactively adapt – by improving records, supporting suppliers, and seeking expert help – will be better positioned as the system matures. Those who resist or ignore the changes risk growing penalties and operational restrictions.

Final Thoughts

The tension between Kenya’s large informal economy and its increasingly formal, digital tax system is real and painful for many SMEs. While KRA’s push toward transparency and efficiency is understandable, the implementation must account for ground realities if it is to succeed without crippling small businesses.

Smart SMEs are treating this challenge as an opportunity to strengthen their operations, build better systems and gradually move toward full compliance. With the right strategies and support, businesses can reduce the pain of transition while positioning themselves for long-term success in a more formal economy.
