What is the main purpose of the Internal Revenue Service (IRS)?

The main purpose of the Internal Revenue Service (IRS) is to enforce, administer, and collect federal taxes. As an agency within the Department of Treasury, the IRS is responsible for ensuring that taxpayers comply with tax laws, filing accurate returns, and paying their taxes in a timely manner. The IRS also provides taxpayer assistance and education to help individuals and businesses understand and meet their tax obligations. Beyond this, the IRS plays a crucial role in maintaining the integrity of the tax system by conducting audits and investigations to uncover tax fraud and evasion. Through its various functions, the IRS safeguards the financial well-being of the United States by funding important government programs and services through the collection of taxes.
