What Is an IRS Audit? Triggers, Process, and Your Rights

The Internal Revenue Code (IRC) governs tax audits, affecting millions of taxpayers. The IRC applies to all taxpayers, including individuals and businesses, with a $500,000 threshold for certain audit exemptions.

As of January 1, 2018, the Tax Cuts and Jobs Act (TCJA) introduced significant changes to the tax code, impacting audit triggers and procedures.

Audit Definition and Framework

The IRS conducts audits under Section 6201 of the IRC, which authorizes the agency to examine taxpayer returns to ensure accuracy and compliance. Audits may be triggered by discrepancies in reported income, exceeding the $10,000 threshold for cash transactions. The IRS typically has a 3-year time limit to initiate an audit, starting from the date the return was filed.

This is where the law gets teeth, as audits can result in significant penalties and fines, including a 20% accuracy-related penalty under Section 6662 of the IRC. In plain terms, taxpayers must maintain accurate records to support their returns, with a minimum 4-year record retention requirement. The IRS may also impose a $5,000 penalty for failure to file certain information returns.

The IRS uses a risk-based approach to select returns for audit, considering factors such as income level, with a higher scrutiny for returns exceeding $1 million in income. Taxpayers with complex returns, including those with multiple Schedule C businesses, may also face increased audit risk. The IRS has a 30-day time limit to respond to taxpayer inquiries regarding audit notices.

Audit Types and Categories

The IRS conducts several types of audits, including correspondence audits, office audits, and field audits, each with distinct procedures and thresholds. For example, correspondence audits typically involve returns with errors or discrepancies below the $10,000 threshold.

Correspondence Audits

Correspondence audits are typically used for simpler returns, with a $5,000 threshold for examination. The IRS has a 2-month time limit to complete correspondence audits, which are usually conducted via mail. Taxpayers must respond to audit notices within 30 days to avoid additional penalties.

Office Audits

Office audits are more comprehensive, with a $20,000 threshold for examination. These audits are typically conducted in person, with a 6-month time limit for completion. Taxpayers must provide detailed records and supporting documentation to substantiate their returns.

Field Audits

Field audits are the most thorough, with no specific threshold, and may involve multiple years and entities. These audits can last up to 12 months, with taxpayers facing potential penalties and fines exceeding $50,000. The IRS may also impose a 75% fraud penalty under Section 6663 of the IRC.

Audit Process and Procedures

The audit process typically begins with a notice from the IRS, which has a 30-day time limit to respond. Taxpayers must provide supporting documentation and records, with a minimum 4-year record retention requirement. The IRS has a 6-month time limit to complete most audits, although complex cases may take longer.

In practice, this means taxpayers must be prepared to provide detailed records and explanations to support their returns. The IRS may also request additional information, with a 30-day time limit for response. Taxpayers facing audits may want to consider seeking professional representation, with fees ranging from $500 to $5,000.

The IRS has implemented a Fast Track Mediation program, which allows taxpayers to resolve disputes within 30 days, with a $100 filing fee. This program is available for cases with a disputed amount below $25,000.

Audit Penalties and Fines

The IRS imposes penalties and fines for noncompliance, including a 20% accuracy-related penalty under Section 6662 of the IRC. Taxpayers may face penalties ranging from $500 to $50,000, depending on the severity of the infraction. In plain terms, taxpayers must ensure accuracy and compliance to avoid significant penalties.

California, for example, imposes an additional 10% penalty for state tax noncompliance, with a $1,000 minimum penalty. New York, on the other hand, has a 14.5% penalty for state tax noncompliance, with a $500 minimum penalty. The IRS has a 3-year time limit to collect penalties and fines.

Taxpayers may be able to negotiate penalty abatements, with a $2,500 threshold for consideration. The IRS has a 30-day time limit to respond to penalty abatement requests. In some cases, taxpayers may be eligible for first-time penalty abatement, with a $1,000 threshold for consideration.

Special Situations and Edge Cases

Whistleblower Claims

The IRS has a whistleblower program, which allows individuals to report tax noncompliance in exchange for rewards. Whistleblowers may be eligible for rewards ranging from 15% to 30% of the collected proceeds, with a $1 million threshold for consideration. The IRS has a 2-year time limit to investigate whistleblower claims.

International Taxpayers

International taxpayers may face unique audit challenges, including the requirement to file Form 8938, with a $50,000 threshold for reporting. The IRS has a 4-year record retention requirement for international taxpayers. Taxpayers may face penalties exceeding $10,000 for failure to comply with international reporting requirements.

Non-Filer Audits

Non-filer audits involve taxpayers who have failed to file returns, with a 6-year time limit for the IRS to initiate an audit. Taxpayers may face penalties and fines exceeding $5,000, with a 20% penalty for failure to file under Section 6651 of the IRC. The IRS has a 2-year time limit to collect unpaid taxes and penalties.

Enforcement and Violations

The IRS enforces tax compliance through audits, with a focus on high-risk returns and noncompliant taxpayers. The IRS has a 3-year time limit to initiate an audit, with a 6-year time limit for certain cases involving fraud or substantial understatement of income. Taxpayers may face penalties and fines exceeding $50,000 for noncompliance.

The IRS may impose additional penalties for repeated noncompliance, with a $10,000 minimum penalty. Taxpayers may be subject to criminal prosecution for severe cases of tax evasion, with penalties ranging from $100,000 to $500,000. The IRS has a 6-year time limit to investigate and prosecute tax crimes.

Recent Changes and Current Status

The Taxpayer First Act of 2019 introduced significant changes to the audit process, including improved taxpayer rights and protections. The IRS has implemented a new audit framework, with a focus on transparency and efficiency. Taxpayers may now request a conference with the IRS Appeals Office, with a 30-day time limit for scheduling.

In plain terms, the IRS is shifting its focus towards a more taxpayer-centric approach, with a emphasis on education and compliance. The IRS has a 2-year time limit to implement new audit procedures and guidelines. As the tax landscape continues to evolve, taxpayers must remain vigilant and proactive in maintaining compliance and avoiding audit risks.
