Wrong VAT retail scheme overpaying VAT
Retail schemes are the practical mechanic for splitting zero-rated and standard-rated takings in a pharmacy that cannot itemise every sale. The wrong scheme systematically overpays VAT, often for years before anyone notices. Because NHS-dispensed prescription drugs are zero-rated and most OTC retail is standard-rated, a pharmacy almost always reclaims more input VAT than a pure retailer expects. The scheme selection matters.
