What Is Tax Form 1040?

How to Use the Tax Form 1040
The 1040 tax form can be intimidating. Organizing your tax preparation information makes this income tax return easier to complete. Form 1040 is divided into three sections that collect personal, income, and deduction information. To avoid being overwhelmed, take it one section at a time.
Section 1: Personal Information
Gather the names and Social Security numbers of everyone living in your household. Follow the prompts to fill in all personal information. You’ll provide basic information such as your marital and filing statuses — if you’re single or married, and if married, whether you’re filing together. Here, Form 1040 will also ask you to claim your exemptions. These tax exemptions should include:
- Your spouse
- Your children
Section 2: Income Information Section
This section of the 1040 tax form asks about your earned income, which can be found on the W-2 federal income tax forms sent to you by your employer. To complete this section of your income tax return you’ll also need to gather information on additional income received via:
- Stock dividends
- Interest income
Section 3: Adjustments to Income
The third section differentiates the 1040 tax form from other federal income tax forms. Using Schedule A will allow you to decrease your taxable income by deducting allowable expenses for items you have paid for. Allowable deductions might include:
- Medical expenses
- State taxes and local
- Real estate taxes
- Home mortgage interest
- Personal property taxes
- Mortgage insurance premiums
- Gifts to charity
- Casualty and theft losses
- Unreimbursed employee expenses
- Tax preparation fees
Calculate your adjusted gross income by subtracting your total deductions from your reported income. The 1040 tax form provides adjustments to income through allowable deductions. More deductions lower your AGI resulting in less federal tax owed. When calculating your final federal taxes, if the amount of taxes you have already paid, as shown on your W-2, is higher than the amount of taxes you calculated using Form 1040, then you’re eligible for a tax refund.
