Top 500 private groups – know your issues and risks

Top 500 privately owned and wealthy groups should document processes to identify and manage their tax issues and risks.

Published 6 February 2025

Our ongoing engagement with groups in the Top 500 tax performance program reveals that many do not have documented procedures for identifying and managing tax issues and risks relevant to the group.

Having documented processes and checks-and-balances in place to recognise and manage issues is our second principle of effective tax management. Following this principle helps Top 500 groups identify and manage issues before they become risks that can impact businesses and lead to exposure to liabilities, penalties, and interest.

All Top 500 groups should have a documented end-to-end process that includes:

  • an environmental scan when the governance framework is first implemented, to identify ‘business as usual’ tax issues
  • keeping an active register of material and tax sensitive issues, and procedures that ensure the right tax treatment of significant transactions, including quantitative and qualitative factors to determine when external advice should be sought
  • a policy that ensures tax is considered when atypical transactions arise, and processes lead to the correct tax treatment
  • clear instructions for preparing tax returns, including record keeping, reconciliations and disclosures, as well as procedures where external tax agents are engaged
  • a process for checking and signing-off tax returns that is recognised within the group and by tax advisers.

Remember that Top 500 privately owned and wealthy groups bear responsibility for the accurate information provided in their tax returns. Those groups need to set up the right processes and checks-and-balances to ensure the integrity of that data before providing it to their tax adviser.
