Case Study: Thorn Grove Schools Limited v Commissioner of Domestic Taxes (Tax Appeal E670 of 2025) [2026] KETAT 69 (KLR) (26 March 2026) (Judgment)
A recent decision by the Tax Appeals Tribunal in Thorn Grove Schools Limited v. Commissioner of Domestic Taxes (Tax Appeal E670 of 2025) offers timely reminders for taxpayers and tax administrators alike. While the case involved multiple issues, two stand out as foundational principles that often get overlooked in practice:
- Related entities are separate legal persons for tax purposes.
- KRA must consider negative variances, not just positive ones, in banking analyses.
Here is a closer look at each lesson and why they matter.
Lesson 1: Related Does Not Mean One and the Same
The Commissioner’s verification exercise included bank statements from Thorn Grove Academy, a partnership related to the Appellant (Thorn Grove Schools Limited). Based on those statements, the Commissioner issued an additional assessment against the company.
The Tribunal rejected this approach unequivocally. Citing the celebrated Salomon v Salomon principle, the Tribunal held that a limited liability company is a distinct legal person from its shareholders, directors, and any related entity. The fact that the two entities shared ownership or business activities did not justify merging their banking transactions for tax purposes.
“That the two parties are related does not mean one of the entities should shoulder tax obligations of the other.”
Key takeaway: KRA must assess each taxpayer based on its own records. Where a related entity’s transactions are erroneously attributed to another taxpayer, the assessment is fundamentally flawed. Taxpayers facing such an error should promptly provide PIN certificates, incorporation documents, and bank statements to demonstrate separate legal identity.
Lesson 2: Negative Variances Cannot Be Ignored
The banking analysis conducted by the Commissioner highlighted periods where bank credits exceeded declared turnover (positive variances) and treated those as undeclared sales. However, for the year 2022–2023, the Appellant’s declared turnover was actually higher than its bank credits—a negative variance of Kshs 5,183,800. The Commissioner omitted that negative variance from the assessment.
The Tribunal found that the Appellant had discharged its burden of proof under section 30(b) of the Tax Appeals Tribunal Act by showing that the assessment would have been different had the negative variance been taken into account. Consequently, the Tribunal directed KRA to amend the assessment to reflect that amount.
Key takeaway: A banking analysis that only adds positive variances while ignoring negative ones is incomplete. Taxpayers should always present the full picture—if KRA uses banking data to allege under-declaration, any period where declared turnover exceeds bank credits must also be factored in.
Practical Implications for Taxpayers
- Maintain clear separation. Even where you own or control multiple entities, keep bank accounts, books, and tax filings strictly separate. KRA cannot aggregate income from one entity and tax another, but it is your responsibility to be able to demonstrate the separation when audited.
- Challenge one‑sided analyses. If an assessment is based on a banking analysis that only captures positive variances, point out the negative variances. The Tribunal has now made it clear that fairness requires both sides of the equation to be considered.
- Document everything. While the Tribunal allowed the appeal on the two issues above, it upheld the disallowance of most expenses because the taxpayer failed to produce primary documents (invoices, receipts, ledgers). Winning on legal principles is not enough—you must also have the records to support your position.
