    How the Internal Revenue Service Works

    The IRS, which has its main office in Washington, D.C., handles all income taxation for businesses and individuals in the United States. It handled more than 261 million tax returns and other forms during the fiscal year 2021. 

    The IRS generated more than $3.5 trillion in revenue during that time and distributed more than $600.1 million in tax refunds. 

    Thanks to computer technology, software, and safe internet connections, both individuals and organizations have the option of filing income tax forms electronically. Since the IRS launched the program, the number of income tax returns that use e-file has steadily increased, and the vast majority are now submitted this way. Nearly 90 percent of all individual returns during FY 2021 used the e-file option.

    However, if you compare that to the number in 2001, roughly 40 million out of nearly 131 million returns, or little under 31 percent, used it.

    What Taxes Does the Internal Revenue Service (IRS) Manage?

    The IRS manages the following taxes:

    • Employment income taxes: The tax you pay on the money you earn from employment. 
    • Individual income taxes: The tax imposed on the earnings of an individual during the year, including wages, salaries, dividends, interest, and other income.
    • Corporate taxes: Tax on a corporation’s profits.
    • Gift taxes: The tax charge on gifts of cash or property made by one living person or business to another.
    • Excise taxes: Indirect levies on the consumption or sale of particular goods, including alcohol, cigarettes, and energy.
    • Inheritance taxes: Inheritance tax is imposed on a decedent’s estate, which includes their assets, money, and things.
