issue- I am a rent a cab service provider. I m in contract with my client to provide the service for fixed rental along with reimbursement of petrol on actual basis. I understand that my rental service is liable for 18% gst.
my concern is- can I issue single tax invoice mentioning non gst taxable goods (petrol) and rental amount. GST is of course only on rental and not on petrol.
