Form 1040

Last updated 29th Nov 2022


The form 1040 is an Internal Revenue Service document that is used to calculate, and file, federal income tax returns each year.


When completing a tax return, it is advisable to fill out the simplest 1040 possible. Although there are numerous 1040 forms, the three most common are:


The 1040EZ is the easiest form to fill out. To qualify for the 1040EZ, the filer must:

  • Have taxable income below $100,000
  • Be single, or married filing jointly
  • Be under the age of 65
  • Not claim any dependents on their tax return


The 1040A is one step above the 1040EZ in difficulty. To qualify for the form 1040A, the filer must:

  • Have taxable income below $100,000
  • Not claim any capital gains or losses (capital gains distributions are allowed)
  • Limit tax credits to those for children, education, earned income, child and dependent care expenses
  • Limit deductions to those taken for traditional IRA contributions, student loan interest, or higher education tuition and fees
  • Not itemize deductions on a 1040A

The third form is referred to as the "standard" form 1040. This is the most complex tax form that applies to individual taxpayers. This form allows taxpayers to take more complex deductions, and additions, to income. The form 1040 is the only income tax form that allows the individual to take itemized deductions.

There are nearly a dozen schedules that can be attached to the form 1040. The most popular being Schedule A, which allows the taxpayer to itemize deductions.
