IRS Audits Explained

IRS Audits Explained

An IRS audit is an examination of an individual's or organization's financial records to ensure that information is reported accurately according to tax laws and that the reported amount of tax is correct. As tax professionals, it's crucial to understand the audit process, recognize common triggers, and guide clients effectively.

Why Are Taxpayers Selected for an Audit?

Selection for an audit doesn't necessarily indicate wrongdoing. The IRS employs several methods to choose returns for examination:

  • Random Selection and Computer Screening: Returns may be chosen based on a statistical formula. The IRS compares tax returns against "norms" for similar returns, developed from audits of a statistically valid random sample as part of the National Research Program. IRS
  • Related Examinations: A return might be selected if it involves issues or transactions with other taxpayers, such as business partners or investors, whose returns were chosen for audit.

Common Audit Triggers

Being aware of factors that can increase audit risk helps in advising clients appropriately:

  1. Unreported Income: All taxable income must be reported. Discrepancies between reported income and information from third-party sources like W-2s or 1099s can trigger an audit. Business Insider
  2. Excessive Deductions: Claiming deductions that are disproportionately large compared to income, such as substantial charitable contributions or business expenses, can raise red flags. Kiplinger+1Investopedia+1
  3. Home Office Deductions: Improperly claiming a home office deduction, especially without exclusive and regular use for business, can attract scrutiny.
  4. Cash Transactions: Businesses with significant cash transactions are more challenging to track and may face higher audit risk. Business Insider+1Sambrotman+1

How Does the IRS Conduct Audits?

Audits are conducted either by mail or through in-person interviews. The interview may occur at an IRS office (office audit) or at the taxpayer's home, place of business, or accountant's office (field audit). The IRS will notify taxpayers by mail and provide all necessary contact information and instructions. IRS

What Documents Are Required?

The IRS will request specific documents to support the income, credits, or deductions claimed on the return. These may include receipts, bills, canceled checks, legal papers, loan agreements, logs or diaries, tickets, medical and dental records, or employment documents. It's essential to maintain organized records to substantiate all claims made on tax returns. IRS

Taxpayer Rights During an Audit

Taxpayers have specific rights during the audit process, including:

  • Right to Professional and Courteous Treatment: IRS employees must treat taxpayers professionally and courteously.
  • Right to Privacy and Confidentiality: Tax matters should remain confidential.
  • Right to Know: Taxpayers should understand why the IRS is asking for information, how it will be used, and what happens if it's not provided.
  • Right to Representation: Taxpayers can represent themselves or have an authorized representative.
  • Right to Appeal: Taxpayers can appeal disagreements within the IRS and before the courts. IRS
