What Was the 1040a Income Tax Form?

The 1040-A was a discontinued IRS tax form that served as a simplified option for filing annual income taxes. It offered more possibilities than the basic Form 1040-EZ but was less complex than Form 1040, designed for taxpayers with straightforward finances who did not itemize deductions. The form was retired by the IRS after the 2017 tax year as part of an effort to streamline the federal tax filing process.

The Historical Purpose and Limitations of Form 1040-A

Form 1040-A was available to taxpayers who met specific criteria, with the primary limitation being a taxable income of less than $100,000. Filers were required to take the standard deduction, as the form did not permit itemizing deductions like mortgage interest or state and local taxes. Income from sources such as self-employment or rental properties required the more detailed Form 1040.

The types of income that could be reported on Form 1040-A included:

• Wages, salaries, and tips
• Interest and ordinary dividends
• Capital gain distributions
• Unemployment compensation
• Taxable scholarships and fellowship grants
• Pensions, annuities, and IRA distributions

While it disallowed itemized deductions, Form 1040-A permitted filers to claim several deductions and tax credits. Taxpayers could claim adjustments for IRA contributions and student loan interest. It also allowed for credits such as:

• The Child Tax Credit and Additional Child Tax Credit
• Education credits like the American Opportunity and Lifetime Learning Credits
• The Earned Income Tax Credit

The Discontinuation of Form 1040-A

The elimination of Form 1040-A was a result of the Tax Cuts and Jobs Act of 2017 (TCJA). This tax reform legislation prompted the IRS to simplify the federal filing process by consolidating the three existing forms—1040, 1040-A, and 1040-EZ—into a single, universal document. The goal was to reduce confusion by having all taxpayers start with the same base form instead of choosing between different versions. The redesigned Form 1040 features a shorter main document for basic information and a series of new, numbered schedules for less common income, deductions, and credits. The retirement of Form 1040-A and 1040-EZ after the 2017 tax year marked the end of the tiered-form system.

Current Filing with the Modern Form 1040

Today, all individual taxpayers file using the redesigned Form 1040. This form functions as a modular document where the main two-page form captures information applicable to most filers, such as filing status, dependents, and standard income. This approach allows those with simple returns to complete just the main form, similar to the experience of using the old 1040-A.

For more complex financial situations, the base Form 1040 is supplemented by numbered schedules. For instance, Schedule 1 is used to report “Additional Income and Adjustments to Income,” which includes items like student loan interest deductions, business income, or alimony. Other schedules handle tax credits and other taxes. This system eliminates the need for taxpayers to determine which form they are eligible to use.

Amending a Prior Year Return Filed with Form 1040-A

If a taxpayer discovers an error on a tax return from 2017 or an earlier year filed using Form 1040-A, they cannot use that form to make corrections. Instead, they must use Form 1040-X, Amended U.S. Individual Income Tax Return. This is the standard form for correcting previously filed personal income tax returns, regardless of which original form was used.

To complete Form 1040-X, the taxpayer will need a copy of their original Form 1040-A return. The amended return requires the filer to enter the figures from the original return, the corrected figures, and the net change between them. This process allows the IRS to see the changes and calculate any additional tax owed or refund due. Prior-year forms, including the 1040-A and Form 1040-X, are available on the IRS website.
