Ok, that's good (in the grand scheme of things) as no amendments we make now will make any difference to accounts you've submitted. We do need to act fairly quick though to ensure your 13/14 accounts go in on time.
As for the VAT returns themselves, unless the corrections are huge it's not big deal, we'll just make an entry so it corrects itself on the next return.
Ok, you need to make a list of the expenses. I'd need to know:
- Which accounting year they fall into (feel free to supply exact dates if you've got the info to hand but not really needed)
- The total amount of the original expense
- The VAT that should've been claimed
- Which 'account' each expense belongs to i.e. travel/stationery/telephone etc (not essential if not easily available but would be handy).
We can then look to post a couple of journals to rectify the situation.
