Form 1040-A of the Internal Revenue Service (IRS) was a simplified version of Form 1040 used by U.S. taxpayers to file an annual income tax return. To have been eligible to use Form 1040-A, an individual needed to meet certain requirements such as not itemizing deductions, not owning a business, and having a taxable income of less than $100,000. Unofficially known as the "short form," Form 1040-A was eliminated for the 2018 tax year in favor of the redesigned Form 1040 that debuted that year.
