Form 1040: U.S. Individual Income Tax Return

Sep 9, 2024 | Personal U.S. expat taxes

Form 1040 is the cornerstone of the U.S. tax system, used by individuals to file their annual income tax return with the Internal Revenue Service (IRS). Whether you live in the U.S. or abroad, this form is essential for reporting your income, deductions, and tax credits.

Fun fact: at 1040 Abroad, our name derives from this very form! We specialize in assisting U.S. expats with their taxation needs, and we are committed to providing zero-cost tax knowledge, including free tax advice. Feel free to reach out with any questions you may have!

What is a 1040 Tax Form?

Form 1040 is the standard U.S. individual tax return form that taxpayers use to file their annual income tax returns with the IRS. It plays a central role in the tax filing process for U.S. citizens. Taxpayers must provide personal details on Form 1040, such as their name, address, Social Security number, and the number of dependents. In addition, they are required to report various types of income, including wages, salary, taxable interest, capital gains, pensions, and Social Security benefits.

Types of Form 1040

The IRS offers four different variations of Form 1040 to meet the needs of various filers:

  1. Form 1040 – This is the standard version used by most U.S. taxpayers.
  2. Form 1040-SR – Specifically designed for individuals aged 65 and older, this form simplifies the filing process. It features a larger font for readability and includes a chart to help calculate the Standard Deduction.
  3. Form 1040-NR – This form is used by nonresident aliens to file their U.S. tax returns.
  4. Form 1040-X – This version is for taxpayers who need to amend a previously filed Form 1040 or request a tax extension.

These variations allow taxpayers to file their returns based on their specific circumstances, making the process more tailored to their individual needs.

Who Needs to File Form 1040?

Populating Form 1040

Most U.S. citizens and resident aliens are still required to file Form 1040 if they meet certain income thresholds. Here are the key points that U.S. expats should keep in mind regarding filing requirements:

Filing Requirements Based on Income

  1. Gross Income Thresholds: U.S. expats must file a tax return if their gross income exceeds specific limits based on their filing status and age. For example, for the tax year 2023:
    • Single: $13,850
    • Married Filing Jointly: $27,700
    • Head of Household: $20,800
  2. Self-Employment Income: If you earn $400 or more from self-employment, you are required to file a tax return, regardless of your total income from other sources. This applies to U.S. expats as well.
  3. Unearned Income: If your unearned income (such as dividends or interest) exceeds $2,750 (or $4,250 if you are 65 or older and blind), you are also required to file a tax return.

Even while living abroad, U.S. expats must stay compliant with U.S. tax laws, making it essential to understand these filing requirements.

What Income Needs to Be Reported on Form 1040?

When filing Form 1040, taxpayers are required to report all income earned during the tax year, including business income, unemployment compensation, and self-employment income regardless whether you live in the U.S. or not.

What is taxable income?

Taxable income encompasses earnings from all sources, such as wages, salaries, and tips. Additionally, taxpayers may need to report income from tax-favored accounts, such as retirement accounts. Form 1040 is also essential for calculating Adjusted Gross Income (AGI), which serves as a critical figure in determining eligibility for various credits and deduction limitations. Properly reporting all income ensures accurate tax calculations and compliance with IRS regulations.

What Deductions and Credits Can You Claim on Form 1040?

Taxpayers can claim various deductions to reduce their taxable income, such as the student loan interest deduction. For U.S. expats, one of the key deductions available is the Foreign Earned Income Exclusion (FEIE), which allows qualifying taxpayers to exclude a portion of their foreign income from U.S. taxation. Additionally, taxpayers may choose to itemize deductions, such as charitable contributions, if they exceed the standard deduction.

In addition to deductions, taxpayers can also claim tax credits to directly reduce their tax liability. Credits such as the refundable Additional Child Tax Credit or the Foreign Tax Credit (FTC) can be applied to lower the total taxes owed. Form 1040 is used to calculate the total amount of deductions and credits claimed, ensuring taxpayers maximize their available tax benefits.

How Do U.S. Expats Report Self-Employment Tax on Form 1040?

U.S. expats who are self-employed must report their self-employment income on their individual income tax return by filing IRS Form 1040. If your net earnings from self-employment exceed $400 in a tax year, you are required to file and report your income, regardless of whether the income was earned in the U.S. or abroad.

To accurately report self-employment tax, expats need to use Schedule C to detail their business income and expenses. Additionally, Schedule SE is required to calculate the self-employment tax, which consists of a 12.4% Social Security tax and a 2.9% Medicare tax, totaling 15.3%. This tax applies to net earnings up to a set limit, such as $168,600 for the 2024 tax year.

U.S. expats may also need to make estimated tax payments if they expect to owe $1,000 or more in taxes when filing their annual return. These payments should be made quarterly to avoid penalties for underpayment. Expats can also utilize tax benefits like the Foreign Earned Income Exclusion (FEIE) or the Foreign Tax Credit to reduce their overall tax liability.

What are the most common tax forms and schedules US expats need to file together with 1040?

U.S. expatriates filing their taxes typically need to complete Form 1040 along with several other forms and schedules to accurately report their income and claim deductions or credits. Here are the most common tax forms and schedules that U.S. expats should be aware of:
