During the fiscal year, IRS employees processed 230 million returns, including individual income, corporation income, and employment income tax returns. We provided $467 billion in refunds to these taxpayers and collected $2.3 trillion for the Federal government, provided taxpayer assistance through 305 million visits to IRS.gov and assisted more than 78 million taxpayers through our telephone helpline or at walk-in sites. Of the 141 million individual income tax returns processed, almost 70 percent were filed electronically.

In 2010, IRS continued to implement the tax portions of the American Recovery and Reinvestment Act. IRS prepared systems and products in a timely manner, enabling taxpayers to take advantage of the ARRA provisions as soon as possible. Individual taxpayers benefited from the Making Work Pay Tax Credit, the First-Time Homebuyer Credit and expanded COBRA health care coverage. And, we helped America's businesses, as they benefited from Net Operating Loss Carryback Adjustments that offset taxable income for the preceding three to five years.

Also in 2010, IRS pursued its international agenda to ensure that taxpayers cannot walk away from their responsibilities by hiding money in offshore accounts. Over the past few years, our voluntary disclosure program and enforcement efforts have brought thousands of taxpayers back into the system, and those numbers are growing.

We also focused on our workforce, making the best use of the talents that lie within our own organization. Our agency showed remarkable improvement in its rankings in the Best Places to Work in the Federal Government survey, getting us closer to my goal of making the IRS the best place to work in government.

IRS has much to be proud of as we look back at Fiscal Year 2010 and our work serving the American public. It is with pride that I give you this year's issue of the IRS Data Book.

Examinations

 

The IRS accepts most Federal tax returns as filed. However, the IRS examines (or audits) some returns to determine if income, expenses, and credits are being reported accurately. Some examinations are handled entirely by mail, while others are conducted in a taxpayer's home, place of business, an Internal Revenue office, or the office of an attorney, accountant, or enrolled agent. The IRS enforces the tax law in a number of ways. For individual taxpayers, some of the more common methods may include:

• sending a notice to a taxpayer because the IRS has an information return that indicates a taxpayer has income, but has not filed a tax return;

• correcting a mistake made by the taxpayer, using its authority to correct math errors and related problems on a return as filed;

• informing a taxpayer that it has a record of income that does not appear on a tax return;

• conducting an examination by mail (correspondence examination); or

• notifying a taxpayer that he or she is being subjected to a face-to-face audit (field examination).

Table 10 provides additional information about those examinations in which the taxpayer did not agree with the IRS examiner's determination. Table 11 provides information on examinations that prevented the erroneous payment of refunds. Table 12 shows the number of examinations that resulted in additional refunds paid to the taxpayer and the amount of refunds recommended. More than 41,000 examinations of individual income tax returns resulted in additional refunds of almost $810 million.

Table 13 provides information about examinations of tax-exempt organizations, such as charitable organizations and foundations, employee pension plans, Government entities, and tax-exempt bonds. These organizations generally do not owe Federal income tax. However, tax-exempt organizations may owe additional payroll taxes, unrelated business income tax, or excise taxes. In addition, changes to exempt organization returns may lead to adjustments on related taxable returns. Examinations of related returns are also included in Table 13 (and excluded from Tables 9a through 12). The IRS processed 776,300 returns of tax-exempt organizations in Calendar Year 2009 and examined 11,449 tax-exempt organization and related returns in FY 2010.

Information Reporting and Verification

 

In the Automated Substitute for Return Program, the IRS uses information returns from third parties to identify tax return delinquencies (nonfilers); constructs tax returns for certain nonfilers based on that third-party information; and assesses tax, interest, and penalties based on the substitute returns.

Table 14 provides information about both the Automated Underreporter Program and the Automated Substitute for Return Program. During Fiscal Year (FY) 2010, the IRS received more than 2.6 billion third-party information returns, almost 88 percent of which were filed electronically. Under its Automated Underreporter Program, the IRS closed 4.3 million cases in which a discrepancy was identified between the taxpayer return and third-party information, resulting in more than $7.2 billion in additional assessments. In FY 2010, under its Automated Substitute for Return Program, the IRS closed almost 1.2 million cases in which a tax return delinquency was identified for nonfilers, resulting in $13.4 billion in additional assessments.

During the routine processing of tax returns, the IRS also checks for mathematical and clerical errors before refunds are paid. Table 15 shows the types of errors made on returns processed. For Tax Year (TY) 2009 individual income tax returns processed during Calendar Year 2010, IRS sent 8.4 million notices to taxpayers for almost 10.6 million math errors identified on their returns. Errors related to reporting the Making Work Pay Credit (MWPC) made up the largest portion of total errors for TY 2009 returns. For nearly 4.8 million MWPC cases, the IRS computed the credit for eligible taxpayers who failed to claim it.

Collections, Penalties, and Criminal Investigation

 

The failure to comply with Federal tax laws may result in civil penalties. Table 17 provides information on penalties assessed and abated during FY 2010, by type of tax and type of penalty. Individuals who deliberately fail to comply with Federal tax laws may also be subject to a criminal investigation, which could result in prosecution, fines, and imprisonment. During FY 2010, the IRS assessed $28 billion in civil penalties. More than half of that amount, $14.5 billion, was assessed in civil penalties on individual and estate and trust income tax returns. IRS also abated $10 billion in civil penalties during the year, including $4.1 billion in abatements for individual and estate and trust income tax returns.

Table 18 summarizes criminal investigation activity related to legal source tax crimes, illegal source financial crimes, and narcotics-related financial crimes. In FY 2010, IRS initiated 4,706 criminal investigations in these three areas.

Legal source tax investigations involve activities, industries, and occupations that generate legitimate income. The Legal Source Tax Crimes Program also includes cases that may threaten the tax system, such as frivolous challenges to the legitimacy of the tax laws; unscrupulous tax return preparers; and fraudulent refund schemes. During FY 2010, the IRS referred more than 1,000 legal source tax crimes cases for prosecution.

Illegal source financial crimes relate to proceeds derived from illegal sources other than narcotics and involve tax and tax-related violations, as well as money laundering. During FY 2010, the IRS referred more than 1,300 illegal source financial crimes cases for prosecution.

The Narcotics Program investigates narcotics-related tax and money-laundering crimes. The IRS often cooperates with the Justice Department and other law enforcement agencies to accomplish its mission. During FY 2010, the IRS referred more than 600 narcotics-related financial crimes cases for prosecution.

Taxpayer Assistance

 

Table 20 provides information about the Taxpayer Advocate Service (TAS). TAS is an independent organization within the IRS that helps taxpayers resolve problems with the IRS and recommends changes that will prevent these problems in the future. Taxpayers may submit an application for assistance to TAS. In FY 2010, TAS received 298,933 applications for assistance and closed 286,298 applications.

Table 21 provides information on the workload of IRS's Appeals Office. The Appeals mission is to resolve tax controversies, without litigation, on a basis that is fair and impartial to both the taxpayer and the Federal government. The Appeals Office considers cases that involve examination, collection, and penalty issues. Taxpayers who disagree with the IRS findings in their cases may request an Appeals hearing. The local Appeals Office is separate and independent of the IRS office that proposed the tax adjustment, collection action, or penalty. During FY 2010, IRS received 135,755 taxpayer cases and closed 133,090 cases. The majority of cases received were taxpayer requests for hearings in response to notices of intent to levy or notices of Federal tax liens.

Tax-Exempt Activities

 

Table 22 summarizes IRS activities, such as issuing technical guidance, to assist tax-exempt entities and facilitate their compliance with Federal tax laws. Table 23 provides information about applications for determination of tax-exempt status for employee pension plans. Table 24 provides information about applications for tax-exempt status that were closed during Fiscal Year 2010. Table 25 shows the total number of approved tax-exempt organizations for Fiscal Years 2007 through 2010. More than 65,000 tax-exempt organizations and other entities, including almost 60,000 religious, charitable, and similar organizations, applied for tax-exempt status during Fiscal Year (FY) 2010. Of those, IRS approved tax-exempt status for almost 54,000 organizations. In FY 2010, IRS recognized more than 1.9 million tax-exempt organizations and nonexempt charitable trusts.

Chief Counsel

 

Attorneys in the Chief Counsel's Office serve as lawyers for the IRS. They provide guidance to the IRS and to taxpayers on the correct legal interpretation of the Federal tax laws, represent the IRS in litigation, and provide all other legal support the IRS needs to carry out its mission.

Tables 26 and 27 provide information about Chief Counsel's workload and case activity in several major categories including criminal tax, international issues, and general legal services in Fiscal Year (FY) 2010. Chief Counsel received 90,359 cases and closed 93,360 cases during the fiscal year. Of cases received, as well as cases closed, the majority were related to tax law enforcement and litigation, including Tax Court litigation; collection, bankruptcy, and summons advice and litigation; Appellate Court litigation; criminal tax; and enforcement advice and assistance.

Almost 30,000 Tax Court cases involved a taxpayer contesting an IRS determination that he or she owed additional tax. The total amount of tax and penalty in dispute was $7 billion.

IRS Budget and Workforce

 

In FY 2010, the IRS collected more than $2.3 trillion, incurring 53 cents, on average, to collect $100.

IRS's actual expenditures for Fiscal Year (FY) 2010 totaled nearly $12.4 billion. IRS's three core operating appropriations are taxpayer services, enforcement, and operations support. Taxpayer services funds processing tax returns and related documents, and assistance for taxpayers in filing returns and paying taxes due. In FY 2010, IRS spent $2.4 billion on taxpayer services. Enforcement funds examination of tax returns, collection of balances, the administrative and judicial settlement of taxpayer appeals of examination findings, and provides resources for strengthened enforcement to reduce invalid claims and erroneous filings associated with the Earned Income Tax Credit (EITC) program. IRS spent almost $5.5 billion on enforcement in FY 2010. Operations support funds administrative services, policy management, and IRS-wide support. The appropriation also funds staffing, equipment, and related costs to manage, maintain, and operate critical information systems that support tax administration. In FY 2010, IRS spent more than $4.1 billion on operations support.

During the fiscal year, the IRS continued to focus on attracting, retaining, and developing a quality workforce to support workforce management activities that contribute to making the IRS one of the best places to work in government. In FY 2010, IRS employed a total workforce of 107,621, including seasonal and part-time employees.

First-Time Homebuyer Credit

 

ARRA expanded the tax credit for first-time homebuyers who purchased a home between January 1, 2009, and December 31, 2009. Under the law, qualified homebuyers were allowed to claim the tax credit either on their 2008 returns (due on April 15, 2009) or on their 2009 returns (due April 15, 2010). Qualified first-time homebuyers -- those who did not own, separately or with a spouse, a home within 3 years of the purchase date -- could claim 10 percent of the home purchase price up to $8,000 or $4,000 for married individuals filing separately. The amount of the tax credit began to phase out for a taxpayer whose adjusted gross income was more than $75,000 or $150,000 for joint filers. The Worker, Homeownership, and Business Assistance Act of 2009, enacted on November 6, 2009, extended and expanded the First-Time Homebuyer Credit (FTHBC) into 2010.

Under these two pieces of legislation, taxpayers could claim the FTHBC on their 2008, 2009, or 2010 tax returns. Table A reports the FTHBC by State and includes original and amended returns with a FTHBC processed between September 27, 2009, and October 2, 2010. In FY 2010, more than 2.1 million returns included a FTHBC claim that was granted by the IRS, Combined, these returns included $15.6 billion in First-Time Homebuyer Credits.
