Computer assisted verification

We use Computer Assisted Verification (CAV) techniques to analyse electronic financial records during our audit and investigation activities.

CAV techniques enable us to analyse your records more efficiently, accurately and thoroughly. We are permitted to copy documents, including electronically-stored information.

We’ll arrange a meeting with you to understand the:

• accounting system you use
• format and extent of electronic records available
• electronic records required
• documentation available to assist in our analysis, such as your chart of accounts, reference tables and data dictionary.

Your tax adviser and information technology specialists are welcome to attend this meeting.

We’ll ask you to download a copy of the agreed electronic information from your system to a virus-free CD, DVD, or other agreed medium.

We recommend you keep a copy of the electronic information you supply, and we’ll confirm in writing what we’ve received.

Data review and analysis

We use specialised CAV software to verify the electronic information you provide is accurate and complete. We then conduct a series of tests on your data to ensure you comply with the relevant tax laws.

Our CAV software does not allow any changes to be made to the data you have supplied.
