What Is a Tax Auditor?

A tax auditor is a financial professional responsible for examining an individual's or organization's financial records to determine whether their reported tax liability complies with applicable tax law and regulations. Operating within the broader field of Taxation and Accounting, these professionals play a crucial role in ensuring the integrity of a nation's tax system. Tax auditors review submitted tax return forms for inconsistencies that might warrant a detailed inquiry or audit. They verify that income, deductions, credits, and other financial data are accurately reported and supported by proper documentation.

History and Origin

The concept of tax auditing is intrinsically linked to the establishment and evolution of centralized tax collection systems. In the United States, the formalization of tax enforcement began significantly after the Civil War, which necessitated the nation's first income tax through the Revenue Act of 1862. This act also created the office of the Commissioner of Internal Revenue, the predecessor to the modern IRS (Internal Revenue Service). The IRS, founded in 1862, is now a bureau of the Department of the Treasury and is responsible for administering the U.S. federal tax laws, a mission that includes helping taxpayers meet their responsibilities and enforcing the law with integrity.¹² Tax auditors became essential components of this system, tasked with verifying the accuracy of federal tax returns and upholding compliance.

Key Takeaways

• A tax auditor evaluates financial records and tax returns to ensure compliance with tax laws and regulations.
• They work for government agencies (like the IRS), or privately as internal or external auditors.
• The primary goal of a tax auditor is to identify and resolve taxpayer errors and ensure accurate reporting.
• Tax audits can be initiated through various methods, including statistical analysis, information matching, and related examinations.¹¹
• Maintaining thorough and accurate financial records is critical for taxpayers in the event of an audit.

Formula and Calculation

Tax auditing does not involve a single, universal formula. Instead, a tax auditor applies tax laws, accounting principles, and established methodologies to verify the calculations presented on a tax return. This involves:

• Verifying Income: Matching reported income against third-party information like W-2 forms, 1099s, and bank statements.
• Substantiating Deductions and Credits: Ensuring that claimed deductions and credits meet legal requirements and are supported by appropriate documentation.
• Reconciling Discrepancies: Investigating any differences between reported figures and available supporting documentation or third-party data.

For example, when examining a business's net income, a tax auditor would verify that:

where each component (Total Revenue, Allowable Expenses) is scrutinized for accuracy and adherence to tax codes.

Interpreting the Tax Auditor's Role

The role of a tax auditor is to ensure fairness and equity in the tax system. When a tax auditor contacts a taxpayer, it indicates that the tax authority, such as the IRS, needs to clarify or verify information on a submitted return. Their findings can result in no change to the original tax liability, a recommendation for additional taxes, or even a refund if an overpayment is discovered. An audit aims to determine if all items, including income, credits, and deductions, were reported accurately according to existing tax laws.¹⁰ The process often involves requesting documentation, which the taxpayer must provide to support their reported figures.

Hypothetical Example

Consider Jane, a self-employed graphic designer. In preparing her tax return, she reported $70,000 in income and claimed $20,000 in business expenses, resulting in a taxable income of $50,000. A tax auditor, during a routine review, might select her return due to a statistically unusual ratio of expenses to income for her industry.

The tax auditor sends Jane a letter requesting receipts, invoices, and bank statements to substantiate her claimed expenses. Jane provides detailed records for her office rent, software subscriptions, and professional development courses. The tax auditor meticulously reviews each item, comparing the amounts to the documentation and ensuring they meet the criteria for legitimate business deductions under current tax law. After verifying all $20,000 in expenses with proper documentation, the tax auditor concludes the audit with a "no change" determination, confirming Jane's original reported tax liability was correct.

Practical Applications

Tax auditors are critical for maintaining the integrity of the tax system and promoting compliance. Their work manifests in several key areas:

• Government Oversight: Government tax auditors, such as those working for the IRS, perform examinations to ensure individuals and businesses correctly report their tax liabilities. This helps reduce the "tax gap," the difference between taxes owed and taxes paid.⁹
• Corporate Governance: Larger corporations often employ internal tax auditors to proactively ensure their financial reporting and tax positions adhere to all applicable regulation before external scrutiny.
• Investigating Non-Compliance: Tax auditors are instrumental in identifying instances of intentional misreporting or fraud, which can lead to penalties or legal action. The IRS has significantly increased its enforcement activities, particularly targeting certain business sectors and high-wealth taxpayers.⁷, ⁸
• Policy Feedback: The data gathered from tax audits can inform policymakers about areas of the tax law that may be unclear or frequently misunderstood, leading to potential legislative changes or guidance.

Limitations and Criticisms

While essential, the work of a tax auditor faces limitations and criticisms. One significant challenge is the sheer volume and complexity of tax laws, which can lead to honest errors by taxpayers and intricate dispute resolution processes.

Moreover, resources for tax auditing agencies, such as the IRS, can fluctuate. For example, between 2010 and 2019, audit rates for individual income tax returns decreased across all income levels, a trend primarily attributed to reduced staffing due to decreased funding.⁶ This can limit the reach and effectiveness of audits in ensuring broad compliance.

From an ethical standpoint, tax auditors, like all financial professionals, must adhere to strict ethical codes. For instance, the American Institute of Certified Public Accountants (AICPA) provides Statements on Standards for Tax Services (SSTSs) that guide members performing tax services, emphasizing integrity, objectivity, and due care.⁵ Critiques sometimes arise regarding the perceived fairness of audit selections or the burden placed on taxpayers to provide extensive financial records.

Tax Auditor vs. Accountant

While both tax auditors and accountants deal with financial records and tax matters, their primary functions and allegiances differ significantly.

A tax auditor primarily acts as an independent verifier, often on behalf of a government entity or an internal control department, to ensure that financial statements and tax returns adhere to established regulation and tax law. Their role is to scrutinize, investigate, and assess compliance.

An accountant, on the other hand, typically works on behalf of an individual or organization to record, organize, analyze, and prepare financial information, including tax returns. Their role is to assist in managing financial affairs, minimize tax liability within legal bounds, and provide financial advice. While an accountant prepares the financial information, a tax auditor examines it for accuracy and adherence to the rules.

FAQs

What triggers a tax audit?

Tax audits can be triggered by various factors, including mathematical errors on a tax return, discrepancies between reported income and third-party information (like W-2s or 1099s), unusually large deductions for one's income level, or random selection as part of an IRS compliance program.⁴

How long does an IRS audit typically take?

The duration of an audit can vary widely depending on the complexity of the tax return and the issues being examined. Some simple audits conducted by mail may conclude in a few months, while more complex field audits involving businesses can take a year or more. The IRS generally tries to audit returns as soon as possible after they are filed, typically within the last two years.³

What documents should I keep for a tax audit?

For a tax audit, it is crucial to keep all relevant financial records that support the figures on your tax return. This includes W-2s, 1099s, receipts, invoices, bank statements, canceled checks, and any other documentation related to your income and deductions. The law generally requires taxpayers to keep records for at least three years from the date the tax return was filed.¹, ²

Can a tax auditor conduct a criminal investigation?

While a tax auditor's primary role is to verify compliance with tax law and assess civil liabilities, if they uncover evidence of potential criminal fraud, the case can be referred to the criminal investigation division of the tax authority. This transition involves different procedures and legal implications.

What are my rights during a tax audit?

Taxpayers have specific rights during an audit, often outlined in a "Taxpayer Bill of Rights." These rights include the right to be informed, the right to quality service, the right to pay no more than the correct amount of tax, the right to challenge the IRS's position and be heard, and the right to privacy. Taxpayers can also be represented by an accountant, attorney, or enrolled agent during an audit.
