A new High Court decision has handed businesses a major new responsibility: proving not just their own tax compliance, but also that of their suppliers.
In a ruling that could reshape how companies keep records and claim VAT, the court held that an invoice alone is no longer enough to justify input tax deductions. Taxpayers must now demonstrate that a supplier genuinely exists, is capable of delivering what they claim to supply, and actually provided the goods or services listed.
In simple terms, investigative work traditionally carried out by the Kenya Revenue Authority (KRA) has now shifted directly to businesses even when a company acted in good faith.
At the Port of Mombasa, trucks and containers move in tight lines every evening, a reminder of how much paperwork and verification underpins the country’s trade. But under the court’s new interpretation, paperwork is no longer proof on its own.
The decision is anchored in Section 17 of the VAT Act, which allows VAT deductions only where a genuine supply occurred. The court emphasized that “documentation without substance” will no longer meet this threshold.
This means a business can now be penalized or have its VAT claims denied simply because its supplier was non-compliant, even if the business was unaware.
How the Case Began
The ruling arose from a dispute involving a company audited by KRA. Investigators flagged several VAT claims linked to “missing traders” suppliers who existed on paper but could not be traced, raising doubts about whether they ever delivered goods.
For years, many taxpayers assumed that as long as they had invoices and receipts, their transactions were protected. But the court disagreed, noting that an invoice does not prove an actual supply.
The new standard requires businesses to provide stronger evidence such as:
delivery notes,
transport or courier logs,
weighbridge tickets,
warehouse entry records,
proof of payment and reconciliation documents.
For small and medium-sized enterprises already battling tight margins, high taxes and rising costs the new administrative burden could be heavy. Many rely on informal suppliers or do not have the capacity to maintain elaborate verification systems.
Bank Deposits Also Under Scrutiny
The ruling also addressed the treatment of unexplained bank deposits. In the case before the court, KRA had flagged significant deposits that did not match the company’s declared income.
The firm argued that some of the deposits were loans or inter-bank transfers. But without strong documentation to back the claims, the court held that any deposit is presumed to be income unless proven otherwise.
Verbal explanations or informal statements will no longer suffice. If you cannot produce written proof, KRA is free to tax the deposit.
What It Means for Businesses
Accountants and tax experts say the ruling marks one of the most consequential shifts in tax compliance in recent years. It essentially turns businesses into frontline investigators of their own supply chains.
A Nairobi tax consultant who works with SMEs summed it up:
“The risk has moved. If your supplier fails, you fail. Even if you did everything right.”
For now, the business community is waiting to see whether the decision will be challenged or whether KRA will issue guidelines to help taxpayers comply. But the message from the bench is clear VAT claims must reflect real transactions, backed by real proof.
As the dust settles, businesses are being urged to vet suppliers more thoroughly, strengthen their documentation practices, and treat every bank deposit as something that must be accounted for on paper.
The ruling may be technical, but its impact will be felt from small garages and wholesalers to large manufacturers and importers. In an economy already under strain, the cost of missing paperwork just got a lot higher.
