VAT invoice issued in a foreign currency

A foreign company issued a VAT invoice in a foreign currency for its contractor. They included the VAT amount in GBP in the note on VAT invoice. The accounting program converted the invoice value at a slightly different exchange rate than the one used by the seller, therefore VAT is recorded in a different value than the one shown on the invoice. What VAT value should be indicated on the VAT Return, the one from the VAT invoice or the one from the accounting program? Thank you in advance

Use the VTA as shown on the invoice. The amount of VAT shown as GBP on the invoice is what the supplier will have paid to HMRC, if you now reclaim a different amount, then you could be reclaiming either more VAT or less VAT than HMRC actually received from the supplier. This is why a UK VAT invoice can be in any currency but there must be a GBP equivalent shown for the VAT element. https://www.gov.uk/guidance/foreign-currency-transactions-vat-and-tour-operators

Hi Patrycja M,
If the supplier is charging UK VAT then the amount detailed on the VAT invoice in GBP should be the amount used by all parties on the VAT returns so that the figures match up.
Thank you.
