Today we'll dive deeply into IRS Form 1040A – one of the core tax forms Americans use yearly.

This guide will help explain what 1040A is, who should use it, and how to fill it out so you can confidently tackle your taxes.

Overview of IRS Form 1040A

IRS Form 1040A, also known as the "U.S. Individual Income Tax Return," was a simplified version of the standard Form 1040. It was designed to accommodate taxpayers with relatively straightforward tax situations who met specific eligibility criteria.

The Form 1040A was available to individuals with taxable income below $100,000. It was commonly used by taxpayers who opted to take the standard deduction instead of itemizing deductions.

This form was unsuitable for individuals who had dependents or needed to claim certain adjustments to income, such as student loan interest deductions or self-employment tax.

The 1040A form consisted of two pages and included sections for reporting various types of income, such as wages, salaries, dividends, and interest. It also provided spaces to claim tax credits, such as the Child Tax Credit and the Retirement Savings Contributions Credit. Taxpayers could use this form to report any federal income tax their employers withhold.

Who should use Form 1040A and why
