IIA 2024 Standards Fix Critical Audit Gaps Fast

If your internal audit function is still relying on legacy frameworks, transitioning to the IIA 2024 standards is no longer something to push off to next quarter. The updated IIA 2024 standards bring a much needed, practical shift to how risk teams structure documentation, engage with audit committees, and demonstrate value.

This guide covers what changed, what the five domains actually mean in practice, and a step-by-step checklist your team can use to confirm conformance. Most teams working through this transition find it also surfaces the need for structured internal audit software to manage the documentation and evidence requirements the new standards introduce.

What are the IIA 2024 Global Internal Audit Standards?

The IIA Global Internal Audit Standards were released on January 9, 2024 by the Institute of Internal Auditors and became mandatory for all internal audit functions on January 9, 2025.

They replace the 2017 International Standards for the Professional Practice of Internal Auditing. The 2024 framework organizes the Global Internal Audit Standards into 5 Domains, 15 Principles and 52 Standards.

Each Standard contains three components:

• Requirements — what an internal audit function must do
• Considerations for Implementation — how to apply the requirement in practice
• Examples of Evidence of Conformance — what documentation demonstrates you are meeting the standard

The standards apply to all internal audit functions globally, regardless of size, sector, or geography.

What changed from the 2017 standards to IIA 2024?

The 2024 standards are not a minor update. They represent a structural overhaul of how internal audit functions are expected to operate, document, and report. The key changes are:

• Single consolidated document. The 2024 Global Internal Audit Standards use an integrated structure of domains, principles and standards.
• New Domain structure. The 2017 standards organized requirements into two categories. The 2024 standards use five Domains that cover the full lifecycle of an internal audit function, from purpose and ethics through governance, management, and delivery.
• Stronger Audit Committee governance. The standards introduce an entirely new section on governing the internal audit function. The board and audit committee now have explicit, defined responsibilities, not just the Chief Audit Executive.
• CAE independence confirmation required annually. The Chief Audit Executive must formally confirm organizational independence to the audit committee on an annual basis. Annual confirmation was also required under the 2017 standards; it is not a new 2024 obligation.
• Finding ratings now recommended. Standard 14.3 requires findings to be prioritized by significance using the CAE’s methodology. A rating or ranking is one way to communicate that priority.
• Risk-based planning remains central. Risk-based planning was already explicit in the 2017 standards. Standard 9.4 of the 2024 framework addresses the internal audit plan, including documented assessment, resources and timely updates.
• Quality assurance requirements strengthened. External quality assessments are still required every five years. Internal assessments must now be more systematic and the results communicated to the audit committee.

The 5 Domains of the IIA 2024 Standards explained

The five domains are the structural backbone of the 2024 standards. Every one of the 52 supporting Standards sits within one of these domains.

Domain 1 — Purpose of Internal Auditing Defines why internal audit exists and what it is meant to contribute to the organization. Covers the definition of internal auditing and the mandatory elements that every internal audit function must uphold.

Domain 2 — Ethics and Professionalism Covers the Code of Ethics that all internal auditors must follow, integrity, objectivity, confidentiality, and competency. Also covers ongoing professional development requirements for the audit team.

Domain 3 — Governing the Internal Audit Function This is the most significant new domain. It codifies the board and audit committee’s responsibilities in establishing, supporting, and overseeing the internal audit function. The audit committee must ensure the function is adequately resourced, appropriately positioned, and operationally independent. Saudi organizations should evaluate this domain alongside the governance rules applicable to their entity.

Domain 4 — Managing the Internal Audit Function Covers how the Chief Audit Executive runs the function, strategic planning, resource management, quality assurance, policies and procedures, and communication with senior leadership. The annual audit plan, resource allocation, and performance reporting all sit here.

Domain 5 — Performing Internal Audit Services The operational domain. Covers how individual audit engagements are planned, executed, documented, and reported. Finding management, evidence collection, engagement communication, and follow-up all fall under Domain 5. This is where most of the day-to-day work of an internal audit team happens.

What IIA 2024 means for internal audit teams in Saudi Arabia and GCC

For Saudi internal audit teams, the IIA 2024 standards provide a professional framework for evaluating internal audit practices. Applicable legal and regulatory obligations vary by sector and entity; do not assume that one common requirement applies to every Saudi organization.

At the same time, Saudi audit functions are dealing with requirements that do not exist in most global IIA guidance: NCA Essential Cybersecurity Controls audits, ZATCA tax compliance reviews, and SAMA framework requirements for financial institutions. The 2024 standards are broad enough to encompass all of these, but applying them to the Saudi context requires deliberate mapping rather than a generic implementation.

Structured tools can help teams connect risk assessments, audit plans, engagement evidence and reporting. Evaluate that workflow using your own planning and documentation needs rather than relying on unverified efficiency claims.

For GCC teams navigating IIA 2024 alongside local regulatory frameworks, purpose-built internal audit software for Saudi Arabia makes conformance documentation significantly more manageable.

How to implement IIA 2024 standards: a practical checklist

This checklist covers the core steps for an internal audit function transitioning to the 2024 standards. It is not exhaustive, the full implementation guidance from the IIA goes into greater depth, but it covers the actions that most teams need to prioritize.

Step 1 — Conduct a gap analysis against the 52 Standards. Map your current policies, procedures, and practices against each of the 52 supporting Standards. Identify where you already conform, where you partially conform, and where gaps exist. This is the starting point for everything else.

Step 2 — Update your audit charter. The audit charter should reference the IIA 2024 Global Internal Audit Standards specifically. It should reflect the updated independence requirements, the CAE’s relationship with the audit committee under Domain 3, and the function’s mandate under the new framework. Present the updated charter to the audit committee for formal approval.

Step 3 – Review your annual audit plan against Standard 9.4 in Domain 4. Connect proposed coverage to a current, documented assessment of objectives and risks, identify resources and record approval. Use our risk based audit planning guide for a worked capacity example and a practical coverage checklist.

Step 4 — Establish the CAE independence confirmation process. The Chief Audit Executive must confirm organizational independence to the audit committee at least annually. Create a formal process for this, a written confirmation, documented in audit committee minutes. This should happen every year going forward.

Step 5 — Introduce finding ratings into your reporting. Evaluate whether findings are prioritized by significance using the CAE’s established methodology. If you use ratings such as high, medium and low, define the criteria and apply them consistently; labels alone do not demonstrate that the evaluation is sound.

Step 6 — Review your audit committee reporting against Domain 3. Domain 3 defines what the audit committee needs from the internal audit function to fulfil its oversight responsibilities. Review your current reporting and confirm that the committee is receiving what the standards now require, including progress against the annual plan, quality assurance results, and resource adequacy.

Step 7 — Document conformance evidence for each Standard. The 2024 standards include examples of evidence of conformance against each requirement. Use these as a guide to document how your function meets each Standard. This documentation is what you would present during an external quality assessment.

How internal audit software supports IIA 2024 conformance

The documentation and evidence requirements of IIA 2024 are significantly more structured than the 2017 standards. Risk-based audit plans need to be traceable to a risk assessment. Finding ratings need to be applied consistently. Audit committee reporting needs to reflect current engagement status rather than a manually assembled summary.

Managing all of this on spreadsheets is possible for small teams running a handful of audits. For teams managing ten or more engagements across multiple entities, the manual overhead becomes the biggest barrier to conformance.

Abilite connects audit planning, engagement work, findings, reporting and follow-up. Its capabilities include audit universe mapping, planning risk assessments and resource alignment. Assess configuration, approval workflows and reporting against your methodology during a demonstration; software ownership alone does not establish conformity with IIA standards or SOCPA requirements.
