Credit Note / Debit Note Calculator
Adjustment value with proportional GST reversal for returns, rate corrections or post-sale discounts.
Formula
Credit notes reverse output GST (the supplier reclaims it) but only if the recipient reverses the corresponding input credit — that's why GSTR linkage matters. The §34 deadline to declare a credit note is 30 November following the financial year or the annual return, whichever is earlier; miss it and the GST sticks.
