KRA Audit in Kenya 2026: What Small Businesses Should Prepare

For Kenyan SMEs, the important 2026 tax shift is not only filing a return on time. It is being able to support the income and expenses declared in that return.

KRA's 2026 filing guidance for the 2025 year of income says the filing window runs from 1 January 2026 to 30 June 2026. The same guidance highlights income and expense validation, with the legal basis linked to Section 23A of the Tax Procedures Act, 2015 and the Tax Procedures (Electronic Tax Invoice) Regulations, 2024.

That means a business plan, cash-flow plan, or tax file should assume one thing: unsupported expenses are a risk.

What KRA may want to understand

In a review or audit query, a small business should be ready to explain:

• Sales declared in the return
• Expenses claimed in the return
• eTIMS invoices issued to customers
• Valid electronic tax invoices received from suppliers
• Bank deposits and withdrawals
• Mobile money collections and payments
• Payroll, PAYE, SHA, NSSF, or other staff-related records where applicable
• VAT, withholding tax, turnover tax, or instalment tax position where applicable
• Customs import records where applicable

Not every business has every tax obligation. A sole trader, VAT-registered company, employer, importer, and professional service firm can have different obligations. The practical point is that the records should match the business model.

Build a simple audit file

Create one folder for each tax year. Inside it, keep:

1. Filed returns and payment slips
2. Sales summary by month
3. Expense summary by category
4. Bank and M-Pesa statements
5. eTIMS sales invoice exports
6. Supplier invoices and receipts
7. Payroll schedules if you employ staff
8. Loan agreements and repayment schedules
9. Asset purchase documents
10. Stock or inventory records if you trade goods

This file is not just for tax. It also improves business planning because you can see true margins, not guessed margins.

Watch supplier invoice risk

For businesses that claim expenses, supplier discipline matters. If a supplier cannot issue a valid electronic tax invoice where required, the buyer may struggle to support the expense during return validation.

Before relying heavily on a supplier, ask:

• Can they issue a valid eTIMS invoice?
• Does the invoice show the correct business name or PIN where needed?
• Does the amount match the payment record?
• Are delivery notes, LPOs, or contracts available for larger purchases?

KRA's eCitizen services also include checkers for PINs, tax compliance certificates, control units, and invoice numbers. Those tools are useful when a transaction looks sensitive or high value.

Reconcile before filing

Before filing, compare:

• Sales invoices against bank and M-Pesa receipts
• Supplier invoices against payments
• Payroll records against PAYE filings
• VAT input and output records if VAT registered
• Loan proceeds against bank deposits
• Owner capital injections against bank deposits

The goal is not perfection theater. The goal is a return that can be explained.

Planning implication for SMEs

If you are preparing a bank loan, investor-ready plan, or expansion plan, do not ignore tax records. A lender may ask for bank statements, tax compliance evidence, sales records, or audited accounts. Weak records can make a good business look risky.
