No, in a B2C (business-to-consumer) transaction under the Goods and Services Tax (GST) regime, tax invoices and payment receipts are not the same things.
A tax invoice is a document that is issued by the supplier to the customer, and it contains all the necessary details required under GST laws to record a taxable supply of goods or services.
A payment receipt, on the other hand, is a document that is issued by the supplier to the customer as proof of payment received for the supply of goods or services. A payment receipt typically includes details such as the date of payment, the amount paid, and the mode of payment.
While a payment receipt may contain some of the same information as a tax invoice, it is not considered a tax invoice under GST laws(Sections 46 and 47), and it does not serve the same purpose. The tax invoice is required to be issued to the customer to comply with GST laws, while the payment receipt is issued as proof of payment.
