CST clarification
Whether a seller may reverse excess interstate tax when a buyer later furnishes a C Form is debated: one view requires the invoice to state "C Form due" at sale and disfavors write backs if that procedural step was omitted; the contrasting view permits issuing a credit note or refund after later production of the form, treating goods return time limits as inapplicable and allowing concession claims during assessment or appeal, with any excess tax refundable to the buyer. (AI Summary)
We have charged full rate of tax for an interstate customer for not issuing "C" form. If the customer subsequently issue the "C" form within 6 months can we adjust the differential tax charged excess by issuing the Credit note. If the transaction is clear please provide the relevent notification for our record to convince customer.
