Advantages of tax reviews. A tax review is a verification of tax solutions and calculations applied by the business. It is designed to identify areas of non-compliance and tax savings. It is a meeting of experienced tax consultants with the tax and finance function combined with analysing source documents. The review culminates in a confidential report with recommended tax risk mitigation measures and identified tax efficiencies. The desirable practice is to review at least annual corporate income tax and VAT compliance. For more, see the leaflet here.
