Essential Steps for VAT Audit Preparation

An HMRC VAT audit can be a stressful experience for any business, but proper preparation can make the process smoother and help avoid penalties. Here's our comprehensive guide to getting ready for a VAT inspection.

1. Understand What HMRC Looks For

HMRC typically examines several key areas during a VAT audit:

  • Accuracy of VAT returns and calculations
  • Proper documentation of sales and purchases
  • Correct application of VAT rates
  • Evidence of due diligence in VAT processes
  • Compliance with Making Tax Digital (MTD) requirements

2. Organize Your Records

HMRC can request up to 6 years of records. Ensure you have:

  • Complete sales and purchase invoices
  • VAT account showing how each return was calculated
  • Import/export documentation if applicable
  • Records of any VAT adjustments or corrections

Digital records are preferred under MTD, but paper records must be legible and complete if used.

3. Conduct a Self-Review

Before the audit, review your own records to identify and correct any issues:

  • Verify that input and output VAT calculations are accurate
  • Check that VAT has been correctly applied to all transactions
  • Ensure all required documents are present and properly filed
  • Identify any areas of potential concern and prepare explanations

4. Prepare Your Team

Key staff members should understand:

  • What to expect during the audit process
  • How to locate requested documents quickly
  • Who will be the main point of contact with HMRC
  • What information they are and aren't authorized to provide

5. During the Audit

When HMRC arrives:

  • Be cooperative but don't volunteer unnecessary information
  • Have a dedicated workspace prepared for the inspector
  • Take notes of all questions asked and documents reviewed
  • Ask for clarification if you don't understand a question

6. After the Audit

Once the audit is complete:

  • Review any findings or recommendations from HMRC
  • Implement corrective actions for any identified issues
  • Consider whether you need to make voluntary disclosures
  • Update your processes to prevent future errors
