The Office of the Commissioner of Internal Revenue was established by act of July 1, 1862 (26 U.S.C. 7802). The Internal Revenue Service (IRS) administers and enforces the internal revenue laws and related statutes, except those relating to alcohol, tobacco, firearms, and explosives. It collects the proper amount of tax revenue, at the least cost to the public, by efficiently applying the tax law with integrity and fairness. The IRS aims for the highest possible degree of voluntary compliance in accordance with the tax laws and regulations; advises the public of their rights and responsibilities; determines the extent of compliance and the causes of noncompliance; properly administers and enforces the tax laws; and continually searches for and implements new, more efficient ways of accomplishing its mission. The IRS ensures satisfactory resolution of taxpayer complaints; provides taxpayer service and education; determines, assesses, and collects internal revenue taxes; determines pension plan qualifications and exempt organization status; and prepares and issues rulings and regulations to supplement the provisions of the Internal Revenue Code.

Most of the collected revenues depend on the individual income tax and the social insurance and retirement taxes. Other major revenue sources are corporate income, excise, estate, and gift taxes. The 16th Amendment of the Constitution, ratified on February 3, 1913, gave Congress the authority to levy taxes on the income of individuals and corporations.

Freedom of Information Act (FOIA)

In 1966, President Lyndon B. Johnson's approval of the FOIA gave the right to access documents or records belonging to the executive branch of the Federal Government to any person. The statute is based on the presumption that the Government and its information belong to the public. The IRS may withhold, however, documents or records shielded from disclosure by one of the statute's nine exemptions, and it must withhold them when disclosure is prohibited by law.

Where's My Refund?

Once the IRS processes a tax filer's return and approves a refund, he or she can check the refund date online. The IRS usually issues a refund in fewer than 21 days after receiving a tax filer's return. Some returns, however, require additional review and, therefore, additional time to process.
