Internal Audit Checklist: Key Areas, Procedures and Questions to Review

Preparing for, or conducting, an internal audit is easier with a practical reference point in hand. An internal audit checklist gives auditors and the businesses being audited a structured way to confirm that the key areas of a review, planning, controls, documentation, and follow-up, are all genuinely covered, rather than relying on memory or an informal sense of what should be checked. This checklist is organized by area, with practical, actionable questions under each one.

How to Use This Internal Audit Checklist

This checklist works as a general-purpose reference covering the areas most internal audits touch in some form, whether the engagement is financial, operational, compliance-focused, or IT-related. Not every item will apply to every engagement. Auditors should adapt it to the specific scope of the audit at hand, and businesses preparing for an internal audit can use the same checklist to identify gaps proactively before an auditor arrives.

1. Planning

• Have the audit’s objectives and scope been clearly defined and documented?
• Has the area being audited been formally notified, with a reasonable timeline for the engagement?
• Has an audit program been developed, setting out the specific procedures to be performed?
• Has the audit team confirmed the resources, staff time, and any specialist expertise needed for the engagement?
• Have initial information requests been sent to the area being audited ahead of fieldwork?

2. Risk Assessment

• Has the area under review been selected based on a documented risk assessment, rather than convenience or rotation alone?
• Have the specific risks relevant to this area, financial, operational, compliance, or technology-related, been identified?
• Has the likelihood and potential impact of each identified risk been assessed?
• Has the strength of existing controls addressing each risk been considered?

3. Policies and Procedures

• Are written policies and procedures available for the process being reviewed?
• Are the policies and procedures current, or do they reference outdated systems, roles, or requirements?
• Do actual practices in the area match what is documented in policy, or has practice drifted from what is written?
• Are policies communicated to, and understood by, the staff responsible for following them?

4. Internal Controls

• Have the key controls relevant to this area been identified and documented?
• Has each control’s design been assessed, is it structured in a way that could reasonably prevent or detect the risk it targets?
• Has each control’s operating effectiveness been tested, is it actually being applied consistently in practice?
• Are preventive, detective, and corrective controls all represented, or does the area rely heavily on only one type?
• Have any control weaknesses been clearly documented, distinguishing design flaws from operating flaws?

5. Financial Records

• Are financial transactions supported by adequate documentation?
• Have samples of transactions been tested for accuracy against supporting evidence?
• Are reconciliations, such as bank or account reconciliations, being performed and reviewed on a timely basis?
• Are approval and authorization requirements for financial transactions being followed?

6. Compliance

• Have the applicable laws, regulations, and internal policies relevant to this area been identified?
• Has compliance with regulatory filing deadlines and requirements been confirmed?
• Are licenses, permits, or certifications relevant to the area current and properly maintained?
• Have any known or suspected compliance gaps been documented for further review?

7. Operations

• Have key operational processes in the area been mapped or understood through a walkthrough?
• Have obvious inefficiencies, bottlenecks, or duplicated efforts been identified?
• Is resource utilization in the area consistent with what would be expected given its workload?
• Are operational metrics or KPIs, where they exist, being tracked and reviewed by management?

8. IT

• Are user access rights aligned with job responsibilities, with no unnecessary or outdated access?
• Is segregation of duties enforced within relevant systems?
• Are data backup and recovery processes in place and periodically tested?
• Are cybersecurity controls, such as access logging and monitoring, functioning as expected?

9. Documentation

• Is documentation for the area organized and readily available, rather than scattered across systems or individuals?
• Are records retained for the required period under applicable policy or regulation?
• Have documentation gaps, missing approvals, unsigned agreements, absent supporting records, been noted?

10. Audit Evidence

• Is the evidence gathered sufficient in quantity to support the conclusions being drawn?
• Is the evidence appropriate in quality, relevant and reliable enough to be trusted as a basis for those conclusions?
• Has evidence been properly documented in working papers, with a clear trail from procedure performed to conclusion reached?
• Has confidentiality been maintained over sensitive evidence gathered during the engagement?

11. Findings

• Is each finding structured around condition, criteria, cause, and effect, rather than presented as an unstructured observation?
• Has each finding been assigned a risk rating based on likelihood and potential impact?
• Have draft findings been discussed with management before the report is finalized?
• Do findings focus on root causes rather than only surface-level symptoms?

12. Corrective Actions

• Does each finding have a specific, actionable recommendation attached to it?
• Has management provided a documented response to each finding?
• Has a named owner and a realistic completion date been assigned to each agreed corrective action?
• Are corrective action plans proportionate to the risk level of the finding they address?

13. Follow-Up

• Has a process been established to track the implementation status of agreed corrective actions?
• Have previously identified findings been reviewed to confirm whether corrective actions were actually completed?
• Are outstanding findings past their agreed deadline being escalated and reported to the audit committee or board?
• Is follow-up status being reported on a regular basis, rather than only revisited at the start of the next audit cycle?

Using This Checklist as a Template

This checklist is intended as a general-purpose starting point rather than a rigid, one-size-fits-all document. A financial internal audit will draw most heavily on the planning, financial records, internal controls, and evidence sections, while an IT internal audit will lean more heavily on the IT and documentation sections. Organizations building a recurring internal audit program often adapt a checklist like this into a more detailed, engagement-specific version, with additional questions tailored to the particular process, system, or regulatory environment being reviewed.
