There are two rate for Cab service provider, either he can charge GST @18% with ITC or he can do the billing @5% without ITC. If individual (proprietorship firm) do the billing by opting to pay @5% to body corporate, it comes under RCM. So my query in this is : can service provider do the billing to few body corporate by opting GST @18% with ITC and to few other @5% without ITC which will fall uder RCM and avail the ITC proprotionately in proportion to the billing @18%.
GST Rate for Cab service provider
Motor cab services qualify for either a concessional reduced rate without input tax credit or a standard rate with input tax credit; the non availment condition attached to the reduced rate operates at the supplier level and precludes selective invoice level application of the reduced rate where common inputs are used, unless supplies are demonstrably segregable. Separate notification provisions shift liability to recipients for supplies by individuals to body corporates under the reverse charge mechanism, and ITC used partly for reduced rate supplies must be apportioned or reversed by treating those supplies as exempt for credit reversal purposes.

Hi,
Thank you for your response. However, Notification No. 22/2019 prescribes that when the supplier charges GST at 5% and issues an invoice to a body corporate, the liability shifts under RCM. Importantly, this notification does not restrict the supplier from opting to bill the body corporate at 18%. If such a restriction were implied, it would effectively mean that cab services could only be supplied at a single rate of 5%, which is not the case in practice.
For reference, Notification No. 15/2025 prescribes the rate of 18% (amended from 12% to 18%). Therefore, if we accept the interpretation that services provided to a body corporate are always liable to GST at 5% under RCM, then the rate notification itself should have explicitly stated that the 5% rate applies only to supplies made to non-body corporates.
