When was the last time you thoroughly assessed your business’s internal processes?
For most business owners, financial clarity is crucial, but achieving it can feel overwhelming.
- This is where an internal auditor can make a profound difference.
- By evaluating your organization’s internal controls, operational efficiency, and compliance, they identify improvements that strengthen your business from within.
This blog explores what an internal auditor does, the benefits of hiring one, and how the internal audit process works.
We’ll also touch on career prospects as a Certified Internal Auditor (CIA) and end with tips on preparing for an Internal Revenue Service (IRS) audit.

What Does an Internal Auditor Do?
At its core, an internal auditor is a professional responsible for objectively evaluating an organization’s internal systems, procedures, and practices. Their work ensures your business operates efficiently, safeguards assets, complies with regulations, and identifies risks before they become costly problems.
They focus on areas like:
- Financial Reporting
Making sure financial records are accurate, transparent, and compliant with industry standards and regulations.
- Operational Efficiency
Assessing processes and suggesting improvements to increase productivity while reducing costs.
- Risk Management
Highlighting vulnerabilities that could disrupt operations, such as cybersecurity risks or weak policy enforcement.
- Compliance
Monitoring whether your business adheres to laws, regulations, and internal guidelines.
Many businesses also compare the external audit vs internal auditor roles. Unlike an external auditor, internal auditors work within the organization year-round. Their purpose isn’t just to ensure compliance but to offer valuable insights for optimizing internal performance.
Benefits of Hiring an Internal Auditor
Wondering if your business truly needs an internal auditor?
Here are five reasons hiring one is a smart move:
1. Enhanced Financial Clarity
Internal auditors ensure the financial data is accurate, reliable, and free from misstatements. This clarity improves decision-making at every level of the business.
2. Reduced Risk Exposure
Analyzing operations and highlighting risks helps you mitigate potential losses.
For example, they may identify fraud risk areas or refine cybersecurity protocols to fend off breaches.
3. Improved Operational Efficiency
An internal auditor’s recommendations often save businesses money.
Whether it’s streamlining supply chain processes or reducing redundant tasks, their insights make your operation leaner and more effective.
4. Better Compliance Management
Failing to comply with tax laws or regulations can result in serious penalties.
Internal auditors help implement processes ensuring every department operates within the law.
5. Continuous Improvement
Unlike external audits, which tend to happen annually, internal audits are ongoing.
This provides your operations with constant feedback and allows for scalable improvements over time.
The Step-by-Step Internal Audit Process
If the idea of undergoing an internal audit feels daunting, don’t worry! The process is methodical and designed with the intent to help-not penalize.
1. Planning
The auditor gathers information about your business, sets audit objectives, and scopes out which areas to evaluate.
2. Fieldwork
This phase involves reviewing documents, observing procedures, and interviewing employees to thoroughly understand workflows and internal controls.
3. Risk Evaluation
The auditor identifies risks, ranging from financial inaccuracies to inefficiencies, and maps them according to their impact and likelihood.
4. Review and Recommendations
Your internal auditor will report their findings with actionable recommendations to address weaknesses and bolster strengths.
5. Implementation & Monitoring
The final step involves implementing recommendations and monitoring their implementation over time.
Regular audits don’t just ensure ongoing compliance; they create a culture of accountability and continuous improvement.
How to Prepare for an Internal Revenue Service Audit
Just hearing the phrase Internal Revenue Service (IRS) audit can strike fear into any business owner.
