Understanding the IRS: Structure, Functions, and Enforcement

The Internal Revenue Service (IRS) is the federal agency responsible for administering and enforcing tax laws in the United States. As a cornerstone of the nation’s tax system, understanding how the IRS operates is critical for individuals, businesses, and tax professionals. At the Institute of Corporate & Taxation, our comprehensive US Taxation Course provides learners with essential knowledge about the IRS, its structure, core responsibilities, and how it enforces compliance with federal tax laws.

What Is the IRS?

The IRS is a bureau of the U.S. Department of the Treasury, established to collect taxes and ensure the proper application of tax laws enacted by Congress. While many associate the IRS solely with tax collection, its role is far more extensive.

The Structure of the IRS

The IRS is structured to efficiently manage various aspects of taxation for millions of taxpayers across the country. It is organized into several major divisions:

1. Wage and Investment Division (W&I)

Handles individual taxpayers who earn wages and salaries, including those who file simple tax returns.

2. Small Business/Self-Employed Division (SB/SE)

Focuses on individuals who are self-employed, as well as small businesses that require more complex tax support.

3. Large Business and International Division (LB&I)

Manages tax compliance for corporations, foreign entities, and high-wealth individuals.

4. Tax-Exempt and Government Entities Division (TE/GE)

Oversees nonprofits, government agencies, and retirement plans to ensure compliance with special tax rules.

In the US Taxation Course at the Institute of Corporate & Taxation, students dive deep into each IRS division to understand their unique responsibilities and how they interact with different types of taxpayers.

Core Functions of the IRS

The IRS performs several critical functions that maintain the integrity of the U.S. tax system:

1. Tax Return Processing

The IRS receives and processes hundreds of millions of tax returns each year, including both individual and corporate filings.

2. Tax Collection

It is responsible for collecting federal taxes such as income tax, payroll tax, and corporate tax.

3. Taxpayer Assistance

The IRS offers services and resources to help taxpayers understand and fulfill their tax obligations, including the IRS website, phone support, and tax clinics.

4. Audits and Compliance Checks

To ensure accurate reporting, the IRS conducts audits and uses data analytics to detect discrepancies in filings.

5. Issuing Refunds

The IRS processes and issues tax refunds for eligible taxpayers, typically within a few weeks of return submission.

These processes are explained in detail in our US Taxation Course, where students learn how to navigate the IRS system and interact with it professionally and confidently.

IRS Enforcement: How It Ensures Compliance

One of the most well-known aspects of the IRS is its enforcement authority. When taxpayers fail to comply with tax laws, the IRS may take several actions:

• Audits: Reviews of tax returns to verify accuracy.

• Notices and Letters: Official communications alerting taxpayers to discrepancies or required actions.

• Penalties and Interest: Financial consequences for late filing, underpayment, or inaccuracies.

• Liens and Levies: Legal claims against property or bank accounts for unpaid taxes.

• Criminal Investigations: In severe cases, tax fraud or evasion may lead to prosecution.

Understanding enforcement procedures is essential for both individuals and professionals. The US Taxation Course at the Institute of Corporate & Taxation prepares learners to prevent, respond to, and manage IRS enforcement actions appropriately.
