What Is IRS Form 1040?

IRS Form 1040 is the official form used by U.S. taxpayers to file their annual federal income tax return. It is used to report income, claim deductions and credits, and calculate the amount of tax owed or the refund due. Depending on the taxpayer's situation and types of income, additional schedules or forms may need to be attached.

Form 1040 contains two complete pages with a total of 79 lines, not including attachments. The first page gathers the information about the taxpayer, dependents, income items, and income adjustments. Especially the taxpayer specifies his/her application status and personal allowance on this page.

The second page allows for deductions and credits, calculates taxable amounts based on income figures, and uses the deducted funds for wages or estimates for tax liabilities.

1. Social Security numbers for you, your spouse (if filing jointly), and dependents
2. Income documents such as Forms W-2, 1099 series, SSA-1099, or other income records

1. Your full legal name and Social Security number (must match Social Security Administration records)
2. Your spouse’s information if filing jointly
3. Your current mailing address (use a P.O. box if mail is not delivered to your home)
4. A foreign address, if applicable

Step 3: Choose Filing Status and Dependents

Select the filing status that applies to your situation:

1. Single
2. Married Filing Jointly
3. Married Filing Separately
4. Head of Household
5. Qualifying Surviving Spouse

Your filing status affects your tax rates, standard deduction, and eligibility for credits.

Next, list any dependents you are allowed to claim, including qualifying children or relatives.

Dependents may allow you to claim credits such as the Child Tax Credit or Credit for Other Dependents.

Note: Personal and dependent exemptions no longer exist under current federal tax law. Benefits related to dependents are now provided through credits and deductions.

Step 4: Report Income and Adjusted Gross Income

Report all taxable income, including:

1. Wages, salaries, and tips (Form W-2)
2. Interest, dividends, and investment income
3. Self-employment or business income
4. Retirement income, unemployment compensation, and other taxable sources

Even if you did not receive a tax form (such as a 1099), you are still required to report taxable income.

Some types of income and adjustments are reported through additional schedules (for example, Schedule 1).

These schedules are attached to Form 1040 as needed.

After reporting income and allowable adjustments, you will calculate your Adjusted Gross Income (AGI).

Step 5: Deductions, Tax, and Credits

Next, reduce taxable income and calculate tax:

• Take the standard deduction, or itemize deductions using Schedule A, if itemizing provides a larger benefit
• Use the IRS tax tables or tax computation worksheets provided in the instructions
• Apply credits, such as the Child Tax Credit, education credits, and energy credits

Some situations require additional forms, such as:

1. Form 6251 for Alternative Minimum Tax (if applicable)
2. Form 8962 to reconcile Advance Premium Tax Credit received for health insurance

After applying credits, you will determine your total tax liability.

Step 6: Report Payments and Caculate Refunds and Amount Owed

Report all federal income tax you have already paid, including any federal withholding shown on your Forms W-2 and 1099 as well as any estimated tax payments you made during the year.

After adding these amounts, compare your total payments with your total tax liability.

If your payments are greater than the tax you owe, you are entitled to a refund; if your tax liability is greater than your payments, you will owe additional tax.

Refunds may be received through direct deposit into one or more bank accounts, applied to your next year’s tax obligation, or used to purchase U.S. savings bonds.

If you owe tax, you can pay electronically, by check, or through IRS-approved payment plans.

Step 7: Third-Party Designee, Signature, and Filing

You may optionally authorize a third-party designee (such as a friend or preparer) to discuss your return with the IRS.

Then you can sign and date the return (both spouses must sign if filing jointly).

You should include a daytime phone number.

If filing by mail, attach required withholding forms (such as W-2s) to the front of the return.

Remember, unsigned returns are considered invalid.
