Internal Audit Checklist for UAE Businesses

2025-09-16 · 4 min read · By Aureus Worldwide

Internal audit is one of the most underused tools available to a growing business. Where a statutory audit confirms whether your financial statements are fairly stated, internal audit asks a different question: do your processes, controls and risk management actually work? For UAE businesses scaling up, building an internal audit function, even a lean one, catches problems early, strengthens governance and reduces the risk of fraud and error. This checklist sets out how to plan and run an effective internal audit.

The distinction from external audit matters. An external auditor looks backwards at a set of financial statements and gives an opinion to outside parties such as shareholders and regulators. Internal audit looks inwards and forwards, reporting to management or the board, and its purpose is to improve the business rather than to sign off accounts. That difference shapes everything about how it is run: the scope is yours to set, the findings are for you to act on, and the value comes not from the report itself but from the changes it drives.

Step 1: define the scope and objectives

Every internal audit needs a clear purpose:

1. Decide which processes or areas to review.
2. Set the objectives for the review.
3. Confirm the period under examination.
4. Agree the reporting line, ideally to the board or owners.
5. Confirm independence from the area being audited.

A focused scope produces actionable findings; a vague one produces noise.

Step 2: build a risk-based plan

Internal audit works best when it targets risk. Assess and prioritise:

Direct your effort to the areas where the impact of failure is highest. Trying to review everything every year is neither realistic nor useful for most businesses, and it spreads limited attention too thinly. A better approach is to score each area on both the likelihood of something going wrong and the damage it would cause, then build a rolling plan that covers the highest-risk areas frequently and lower-risk areas less often. This keeps internal audit proportionate and ensures your effort is always pointed at what matters most.

Step 3: understand the process

Before testing, document how each process is meant to work:

• Map the process end to end
• Identify the key controls
• Note who is responsible at each step
• Spot any obvious gaps in segregation of duties

Our guide to internal controls for SMEs explains the controls worth having.

Step 4: test the controls

Testing is the heart of internal audit. For each key control:

1. Confirm the control exists as documented.
2. Select a sample of transactions.
3. Check the control operated for each.
4. Record exceptions clearly.
5. Assess the impact of any failures.

A control that exists on paper but is not operated is, for audit purposes, no control at all.

Step 5: assess fraud and override risk

Pay particular attention to where controls can be bypassed:

• Management override of approvals
• Concentration of duties in one person
• Manual journals and adjustments
• Unusual or related-party transactions

Even strong controls fail if one person can quietly override them. This is why so many real-world losses involve a trusted, long-serving employee rather than an outsider: they understand the controls well enough to work around them, and their seniority discourages questions. A good internal audit deliberately tests the areas where override is possible, looks for unusual manual entries, and is not afraid to scrutinise the people with the most authority. Independence and a healthy professional scepticism are what make this part of the work effective.

Step 6: document findings

Findings are only useful if they are clear. For each issue, record:

• What you found
• Why it matters (the risk)
• The root cause
• A practical recommendation
• An owner and target date

Step 7: report and follow up

The report is the product, but follow-up is where value is realised:

1. Present findings to the board or owners.
2. Agree an action plan with owners and dates.
3. Track each action to completion.
4. Re-test where appropriate.
5. Carry open items into the next cycle.

A finding without follow-up is a finding that will recur. Our financial controls checklist helps embed lasting improvements.

Keep the approach proportionate

Internal audit should match the size and complexity of your business. A small company may run a light annual review; a larger group may need a continuous programme. Confirm any specific regulatory requirement with the relevant authority.
