FBR Credit Note and Debit Note: When and How to Issue

Understanding Credit Notes and Debit Notes

Credit notes and debit notes are essential documents for adjusting previously issued FBR invoices. They serve different purposes and must be properly issued and submitted to FBR to maintain accurate tax records.

What is a Credit Note?

Definition

A credit note is a document issued by a seller to a buyer indicating that the seller is crediting (reducing) the buyer's account. It effectively reduces the value of a previously issued invoice.

When to Issue Credit Notes

  • Goods Returned: Customer returns purchased items
  • Overcharging: Original invoice had higher price than agreed
  • Quantity Short: Delivered less than invoiced
  • Defective Goods: Items were damaged or defective
  • Post-Sale Discount: Agreed discount applied after invoicing
  • Order Cancellation: Full order cancelled after invoicing

Effect of Credit Note

  • Reduces seller's sales and output tax
  • Reduces buyer's purchases and input tax credit
  • May trigger refund to buyer

What is a Debit Note?

Definition

A debit note is issued when the seller needs to increase the amount charged to the buyer beyond the original invoice.

When to Issue Debit Notes

  • Undercharging: Original invoice was lower than actual price
  • Additional Services: Extra services provided after initial invoice
  • Price Increase: Contractual price escalation
  • Additional Quantity: More delivered than originally invoiced
  • Freight/Handling: Additional charges not in original invoice

Effect of Debit Note

  • Increases seller's sales and output tax
  • Increases buyer's purchases and potential input tax credit
  • Additional payment required from buyer
