The recent Tax Court decision in VAT 32666 may be marked “not reportable” and “not of interest to other judges”, but it could nevertheless become important in disputes involving loyalty schemes, cashback arrangements and conditional rebates. The judgment suggests that, in the context of section 21(1)(c) of the VAT Act, contractual form and documentary structure may outweigh economic substance.
This should interest every VAT practitioner.

The dispute concerned a bank’s “cashback” arrangement. Customers were charged monthly banking fees, on which the bank accounted for output VAT. Customers who met certain criteria — including maintaining loan products with the bank and keeping accounts in good standing — later received credits equal to all or part of those fees. The bank treated these credits as reductions of consideration under section 21(1)(c) and claimed input VAT adjustments accordingly.

SARS disagreed. It argued that there were effectively two separate transactions. The first was the supply of banking services for a monthly fee. The second was the customer’s “behavioural compliance”: maintaining qualifying products, participating in the rewards programme and remaining in good standing. According to SARS, the cashback was therefore not a reduction of the banking fee, but consideration paid by the bank for a separate “service” rendered by the customer.

SARS’s argument was sophisticated because it reflected a classic VAT reciprocity analysis: if one party performs specified conduct in exchange for payment, the payment may constitute consideration for a separate taxable supply.

The Tax Court, however, rejected the argument emphatically.

The court held that section 21(1)(c) requires a factual enquiry into whether previously agreed consideration was altered by agreement, whether “due to the offer of a discount or for any other reason”. Importantly, the court stressed that the VAT Act does not require any particular motive for the reduction, nor does it require the original supply itself to change.

The judgment focused heavily on the contractual and evidential structure of the arrangement:

• the original banking fee was contractually agreed;
• VAT was initially accounted for on the full fee;
• customers were later informed that they could obtain a reduction if the qualifying criteria were met;
• the credited amounts directly matched the previously charged fees; and
• the bank statements described the amounts as “monthly fee rebates”.

For the court, these facts established a reduction of previously agreed consideration. SARS’s attempt to characterise the arrangement as a separate supply by the customer was dismissed as a “conflated interpretation” of unrelated VAT concepts.

What makes the judgment interesting is not only the outcome, but what it reveals about the court’s interpretive approach. The court appears to prioritise the legal and documentary characterisation of the arrangement over its underlying economic functionality.

That creates an important tension.

VAT jurisprudence often emphasises economic reality and reciprocal performance. Yet here the court was reluctant to move beyond the way the arrangement was structured and documented. Once the evidence supported a fee reduction mechanism, the broader commercial purpose of incentivising customer behaviour became largely irrelevant.

The practical implications may be significant. Many modern commercial arrangements blur the line between discounts, incentives and payments for conduct. Banks, retailers, airlines and telecommunications providers routinely reward customers for maintaining prescribed levels of engagement or product usage.

This judgment potentially provides vendors with a roadmap:

• expressly link the rebate to the original fee;
• frame the arrangement as a reduction of consideration;
• ensure the documentation consistently refers to rebates or fee reductions; and
• reflect the adjustment clearly on invoices or statements.

In short, structure and language may matter more than economic character.

The unresolved question is where the line should be drawn. At what point does a “rebate” conditional upon customer conduct cease to be a reduction in consideration and become consideration for a separate supply? The Tax Court did not really answer that question because it viewed the arrangement holistically as a fee reduction mechanism.

Future disputes may test that boundary more aggressively.

For now, however, VAT 32666 serves as a reminder that in section 21 disputes, carefully designed contractual form and documentary consistency may carry considerable weight — perhaps more weight than economic substance itself.
