Why have I received less than I submitted?

If you owe HMRC any money—such as PAYE, previous VAT liabilities, penalties, or interest—HMRC will deduct these amounts from your VAT refund before paying you. At Adsum, we ensure that you receive the correct amount after HMRC’s deductions. You can view a detailed breakdown of any deductions in your account under the “VAT Offsets” section.
