From a GST perspective, advertising space services fall under supply of services. The taxable value covers professional fees for advisory work, planning, analysis, execution support and management of campaigns billed under the same contract.

Registered businesses can usually claim input tax credit when such services are used for promoting taxable supplies, subject to normal ITC conditions.
