What financial document summarizes your taxable income for the year?

The W-2 form is the correct answer because it serves as a summary of an employee's taxable income for the year. Provided by an employer, the W-2 details the total wages earned and the amount of taxes withheld from an employee's paycheck, including federal, state, and local taxes. It is essential for completing individual income tax returns, as it provides the necessary information to report earnings and calculate tax obligations.

In contrast, the other options serve different purposes. The W-4 form is used by employees to inform their employer about their tax withholding preferences, determining how much tax is deducted from their paychecks but does not summarize taxable income. The 1099 form is typically issued to independent contractors or freelancers to report income earned outside of traditional employment but does not consolidate all taxable earnings in the same manner as the W-2. Schedule A is a tax form used for itemizing deductions when filing an individual’s tax return, rather than summarizing income.
