Change of auditor: what the new auditor checks first

A change of auditor resets part of the audit learning curve. The new auditor must understand opening balances, prior-year issues, accounting policies and the quality of evidence before relying on the current-year numbers.

01
The first-year auditor must obtain evidence over opening balances, accounting policies and prior-period matters.
02
Communication with the predecessor auditor, where permitted, can reduce risk but does not replace current audit evidence.
03
Management should prepare prior audit reports, management letters, closing files and reconciliations before fieldwork starts.
Executive summary:
A new auditor first checks opening balances, prior audit results, accounting policies, unresolved recommendations and high-risk balance sheet areas. Management should prepare a first-year audit pack before fieldwork starts.

What does a change of auditor mean?

A change of auditor means the new audit firm must build knowledge of the business, controls, accounting policies and historical reporting issues. Even if the prior year was audited, the new auditor cannot simply assume that opening balances are correct.

Definition: opening balances are the balance sheet amounts at the beginning of the period. Under ISA/KSB 510, the first-year auditor must obtain sufficient appropriate audit evidence that they are not materially misstated.

Opening balances and ISA/KSB 510

Opening balances affect the current year's profit or loss through depreciation, inventory, provisions, deferred tax, receivables, accruals and equity movements. If opening balances are wrong, current-year results can be wrong even when current transactions are recorded correctly.

What will be checked first?

  1. Prior-year audit opinion and any modifications or emphasis paragraphs.
  2. Previous management letter and unresolved recommendations.
  3. Opening balance reconciliations to the prior audited financial statements.
  4. Accounting policies and changes in estimates or policies.
  5. Inventory, receivables, provisions, leases, tax and going concern risks.
  6. Access to predecessor auditor communication where appropriate and permitted.

How should management prepare?

Management should prepare a first-year audit pack: prior financial statements, trial balance bridge, audit adjustments, management letter status, inventory documentation, bank confirmations, tax reconciliations and the current-year closing timetable. This reduces repeated questions and avoids treating the change of auditor as a routine handover.

Frequently asked questions

Does changing the auditor make the audit longer?
Usually yes. A first-year audit often takes 30-50% longer because the auditor must understand the business and test opening balances.
Can the new auditor rely on the previous auditor?
The new auditor may communicate with the predecessor where permitted, but must still obtain sufficient appropriate audit evidence.
What documents should be prepared first?
Prior audited financial statements, audit adjustments, trial balance bridge, management letter status, opening balance reconciliations and key accounting estimates.
