Buying from a GST-registered business

Key requirements

Use the registration search to verify an unfamiliar supplier. GST applies to the final taxable price including service charge. A business can show both inclusive and exclusive amounts only with the inclusive amount at least as prominent. Genuine service-charge hotels and F&B have a limited exception with a prominent notice; a nominal charge added simply to avoid inclusive display does not qualify. Keep the bill and price display if asking about wrongful tax practices. A stated registration number does not make an exempt purchase taxable, so the actual transaction still matters.
