Invoicing & Billing

What is Credit Note?

A document issued by a seller to a buyer reducing the amount owed, typically for returned goods, billing errors, or post-sale discounts.

How It Works

Credit notes adjust the original invoice amount downward. Under GST, a credit note must reference the original invoice and include specific details. It reduces the seller's output tax liability and the buyer's input tax credit. Credit notes must be reported in GST returns (GSTR-1) and should be issued before the earlier of September 30th following the financial year or the date of filing the annual return.

Real-World Example

A customer returns defective goods worth ₹10,000 (plus ₹1,800 GST). The seller issues Credit Note CN-001 for ₹11,800, reducing the customer's outstanding balance.

Frequently Asked Questions

When should a credit note be issued under GST?

When goods are returned, there's a price reduction after supply, the tax charged is higher than actual, or the goods/services are found deficient. It must be issued before the deadline specified under Section 34 of CGST Act.

Does a credit note reduce GST liability?

Yes. The seller's output tax liability is reduced, and the buyer must correspondingly reduce their input tax credit claim for the original invoice.
