When and how to issue credit notes and debit notes, including the VAT adjustment process.
Credit Notes
A credit note is issued when a supply is reduced after the original tax invoice was issued.
When to Issue
Goods returned by the customer
Post-sale discount given
Supply cancelled
Error in the original invoice (overcharge)
Volume rebate or loyalty discount
Requirements
A valid credit note must include:
Clearly marked as "Tax Credit Note"
Supplier name, address, and TRN
Recipient name and address
Reference to the original tax invoice (invoice number and date)
Reason for the credit
Adjustment amount (including VAT)
VAT amount being adjusted
A sequential, unique credit note number
VAT Adjustment
The supplier reduces output tax by the VAT amount on the credit note.
The recipient reduces input tax by the same amount (if registered).
Both adjustments are made in the VAT return for the tax period in which the credit note is issued.
Debit Notes
A debit note is issued when the supply value increases after the original invoice.
When to Issue
Post-sale price increase
Additional charges added after invoicing
Undercharge error in the original invoice
VAT Adjustment
The supplier increases output tax.
The recipient increases input tax (if registered).
Worked Example
A Dubai retailer sells AED 10,000 + AED 500 VAT of goods. The customer returns AED 2,000 worth. The retailer issues a credit note for AED 2,000 + AED 95.24 VAT. The retailer reduces output tax by AED 95.24. The customer (if registered) reduces input tax by AED 95.24.
If the retailer had undercharged (AED 8,000 instead of AED 10,000), they issue a debit note for AED 2,000 + AED 100 VAT. Output tax increases by AED 100.
Practical UAE example
**Dubai Wholesaler**: A wholesaler sells AED 20,000 + AED 1,000 VAT of goods to a retailer. The retailer returns AED 5,000 worth of defective goods. The wholesaler issues a credit note: "Tax Credit Note", reference to original invoice #12345, reason: "Defective goods returned", amount: AED 5,000 + AED 238.10 VAT. The wholesaler reduces output tax by AED 238.10. The retailer reduces input tax by AED 238.10.
Key takeaways
Credit notes are issued when supply value decreases after invoicing.
Must reference the original invoice and show the VAT adjustment.
Debit notes are issued when supply value increases; both parties increase VAT.
