The Umbrella Company stated:
"Although receipts aren't needed for some claimable items, HMRC stipulate that we audit a selection of expense claims for each pay period. So, if your claim is selected for audit you will need to provide the necessary receipts to us otherwise we will have to forward to HMRC for further investigation."
The contractor continues: "The company explained the extra expenses to me by stating that as they are an accounting company they have certain dispensations etc."
At this time no conclusion has been reached, and the company are ceasing to make any further comments.
