What Is IRS Form 1040?

The IRS Form 1040 is the standard form every U.S. taxpayer uses to report income to the Internal Revenue Service. It determines your federal income tax liability, your eligibility for credits, and the amount of your refund.

The form records a comprehensive financial snapshot for the year—income, deductions, credits, and payments. Depending on your situation, additional schedules may be needed to report more complex income sources such as self-employment, rental properties, or investments.

Who Needs to File IRS Form 1040

Most U.S. citizens and residents who earn income above a certain threshold must file. Income can include wages, dividends, self-employment earnings, and more. The filing requirement depends on factors like:

• Filing status: Single, Married Filing Jointly, Married Filing Separately, Head of Household, or Qualifying Widow(er).

• Age and income level: The IRS sets annual minimum income thresholds that change slightly each year.

• Sources of income: Those earning gig income, freelance pay, or investment returns may need to file even if income is below typical thresholds.
