GSTR2B showing our regn no wrongly

If you receive a wrong GST invoice from your service provider that has used your GST registration number for another service receiver, you can reject the invoice on the GSTR-2B portal. To do so, you need to follow these steps12:

Select the checkbox against the invoice and click on the Reject option.

Click the Yes option to proceed further in the pop-up window.

After the successful rejection of invoice details, the invoice status changes from “N” to “R”.

By rejecting the invoice, you can avoid claiming ITC on the wrong invoice and also prevent any mismatch or duplication of ITC. However, you should also communicate with your service provider and ask them to correct the invoice details in their GSTR-1 for the next month
