  • A client in the construction industry was unable to file their VAT return due to inconsistencies in the HMRC database. She resolved this issue by liaising with HMRC to first identify the issue and take appropriate action to update the client details on the database.
  • A client in the consultancy industry was struggling with the reconciliation of foreign currency transactions. This impacted the VAT account. She carried out detailed analysis and verified all foreign currency transactions. She then adjusted the VAT account – avoiding significant overpayments – and further problems with HMRC.
