The total value of any credit notes issued or debit notes received should be included in Box 1. The VAT due on the value of the goods acquired from other EU member states is calculated by multiplying the total amount by the applicable UK VAT rate. Not all goods are liable to VAT at the standard rate of VAT.
The Value-Added Tax (VAT) credit note must show: the date of issue. a unique number. the supplier's full name, address and VAT registration number. the customer's full name, address and VAT registration number. in the case of an intra-Community supply, the customer's VAT identification number in the other Member State.
The supplier's full name, address and VAT registration number. the customer's full name, address and VAT registration number. in the case of an intra-Community supply, the customer's VAT identification number in the other Member State. the reason why the note is being issued.
The VAT credit note relates to services you supplied before your business became VAT registered, so you do not add VAT on to the credit note amount. The rule is: the rate of VAT to be used in a credit note is the rate in force at the time of the tax point of the original supply.
When a Credit Note is issued, it means that the vendor making the supply declares in the VAT Return the output VAT which is increased by the amount of the difference between the VAT due on the transaction and the VAT actually paid on the transaction when the invoice was issued.
