Key Takeaways:

What is IRS Form 1040?

Form 1040, also known as the “U.S. Individual Income Tax Return,” is the essential document to report your income, claim tax deductions and credits, and determine your tax liability (what you owe) or refund. The IRS updates this form annually to reflect changes in tax law.

If your tax situation is straightforward, you must only submit the basic Form 1040. However, if your taxes are more complicated (such as earning income from self-employment, rental properties, or investments), you may need to file additional forms called schedules alongside your 1040.

Tip: The form is updated each year to accommodate changes in tax laws, so be sure to use the latest version available.

Who Needs to File IRS Form 1040?

Most U.S. citizens and permanent residents who earn income must file Form 1040. However, whether or not you must file depends on factors like your filing status, income level, age, and whether you have dependents.

Income Thresholds

The IRS sets income thresholds each year. You may not need to file if your income is below these thresholds. However, if you qualify for tax credits or if you overpaid taxes during the year, you may still want to file to receive a refund.

Here’s a table summarizing the 2024 IRS income thresholds based on filing status and age:

Notes:

• If your income is below the threshold, you generally don’t need to file, but you might still want to if you’re eligible for tax credits or if you overpaid your taxes and are due a refund.
• Married Filing Separately has a unique threshold of $5, meaning you must file regardless of income.

Refer to the latest IRS guidelines or consult a tax professional for precise filing advice.

Tip: Even if you’re not required to file, submitting a Form 1040 could help you claim a refund or take advantage of tax credits like the Earned Income Tax Credit (EITC) or Child Tax Credit.

How to Fill Out IRS Form 1040

Filling out IRS Form 1040 might initially seem complicated, but it breaks down into manageable steps. You can file manually by downloading the form from the IRS website or using tax software to auto-populate the form for you.

1. Provide Your Personal Information

At the top of IRS Form 1040, you’ll fill out basic details, including:

• Your name, address, and Social Security number
• Your filing status (Single, Married, Filing Jointly, etc.)
• The number of dependents you claim (children, elderly relatives, etc.)

Tip: Make sure the names and Social Security numbers are accurate. Errors in this section can delay processing or cause complications.

2. Calculate Your Taxable Income

This section helps you report your income, including wages, self-employment income, dividends, and other sources. From there, you’ll subtract any eligible deductions (such as the standard or itemized deductions) to determine your taxable income—the amount subject to income tax.

Tip: Use the IRS tax tables or tax software to ensure you apply the correct deductions based on your situation.

3. Calculate Your Tax Liability

Once you have your taxable income, you’ll apply the federal tax brackets to determine how much you owe. Afterwards, subtract any tax credits you qualify for (like the Child Tax Credit or Retirement Savings Contribution Credit) to lower your total tax liability.

Tip: Check for tax credits you qualify for, as they directly reduce the amount of tax you owe.

4. Determine Refund or Amount Owed

In the final step, you’ll calculate whether you’ve already paid enough taxes throughout the year through withholding or estimated payments. If you’ve paid too much, you’ll receive a refund. If you owe more, you’ll need to make the payment when you file your return.

Tip: If you’re due a refund, you can directly deposit it into your bank account for quicker access.
