VAT adjustments after a return has been submitted

Hi, I am in the process of completing my year end and my accountant has discovered a number of errors in my VAT claims due to incorrect posting. We have made an amendment will this amendment be picked up when I next run the next VAT return or do I need to make manual adjustments on my return>?
Thanks

Hi @Jago, if the amendments that were made were posted to credit notes then it will be picked up in the next VAT return, if journaled in however, you will need to enter adjustments manually in your VAT return.

It is also recommended to have you adjustments well documented to provide backing information for both HMRC and yourself.
