Applying a discount to a sales invoice
You may on occasion need to give a sales invoice discount that you’ll need to record in your accounts. Before you enter it however, you must determine if the discount needs to be inclusive or exclusive of VAT. If unsure, please consult your accountant.
A discount that is exclusive of VAT will reduce the amount payable for the invoice but will not affect the VAT amount due.
Example:
Sales invoice for €1000 net with €200 VAT = Total payable is €1200
Discount exc VAT of €600 given.
Discount is applied as a net invoice amount
Amount payable is (€1000 – €600) + €200 VAT = €600
This type of invoice discount can be applied at the time of recording payment for the invoice. A discount amount can be entered along with the amount being paid. The invoice VAT amount will be included in full on your next return.
A discount that is inclusive of VAT will reduce the amount payable for the invoice and at the same time reduce the VAT amount due by the relevant percentage.
Example:
Sales invoice for €1000 net with €200 VAT = Total payable is €1200
Discount inc VAT of €600 given.
Discount applied is €500 net + €100 VAT
Amount payable is (€1000 – €500 net) + (€200 – €100 VAT) = €600
In order to apply this type of discount, you must enter an amount or percentage for each line on your invoice. This amount will reduce the net and VAT amounts due and ensure your VAT return includes only the post-discount VAT amount.
