Filing Form 1040 can be challenging when factoring in all the specialized schedules required to report specific types of income, deductions, or credits. Multiple schedules may be necessary to accurately complete a standard 1040 tax return, depending on your financial situation. To simplify the process, here’s a breakdown of the 1040 Form instructions for the 2024 tax year.

Who Needs to File Form 1040?

Form 1040 will always be required for US taxpayers who earn income from employment, self-employment, investment, or other sources. If an individual meets any of the following criteria, they will need to file Form 1040:

  • Your taxable income exceeds the filing threshold
  • You had a self-employment net profit of at least $400 while living abroad
  • You owe Alternative Minimum Tax or additional taxes such as self-employment tax
  • You qualify for refundable tax credits such as the Additional Child Tax Credit

Types of Form 1040

Form 1040 has many versions to accommodate specific tax situations. Here is an overview of the 1040 Forms for the 2024 tax year:

  1. Form 1040: This is your standard tax return used to report income, claim refunds, and determine owed taxes
  2. Form 1040-SR: Almost identical to Form 1040, but with adjustments such as larger text and charts for individuals 65 and over
  3. Form 1040-NR: For nonresident aliens who need to file US taxes
  4. Form 1040-X: Used to amend a tax return if there are errors

What Are IRS 1040 Schedules?

Schedules are additional forms used for situations that do not fit within the main 1040 Form. They help eliminate confusion and allow the IRS to report income and deductions more accurately. The most common additions are schedules 1 through 3 with specialized schedules from A to H.

Schedule 1: Additional Income and Adjustments to Income

1040 Form, Schedule 1 is used for income outside the normal wages and salaries.

  • Additional Income Sources: Capital gains, rental income, business income (from self-employment), unemployment compensation, and alimony received
  • Adjustments to Income: Educator expenses, student loan interest, self-employment tax deductions, contributions to retirement accounts, and health savings accounts

This schedule is particularly important for self-employed individuals, freelancers, and those who receive rental or investment income. The Form 1040 instructions for Schedule 1 provide further details on each deduction or income item for the 2024 tax year.

Schedule 2: Additional Taxes

If an individual owes additional taxes not already included on Form 1040, it must be reported using Schedule 2.

  • Part I for Additional Taxes: Covers Alternative Minimum Tax and excess premium tax credit repayments
  • Part II for Other Taxes: Includes self-employment tax, household employment taxes, additional taxes on IRAs and 401(k)s, and net investment income tax

It’s common for taxpayers to be unaware of their need for Schedule 2 and their additional tax penalties. Sign up and try the MyExpatTaxes tax software to avoid missing a step. With our expat tax software, knowing the difference between each schedule is unnecessary, as we’ll automatically include everything needed.

Schedule 3: Additional Credits and Payments

Schedule 3 is most known for claiming non-refundable and refundable tax credits. This schedule is common for US expats filing Form 1040 abroad.

  • Non-Refundable Credits: Foreign Tax Credits, education credits, general business credits, and credits for older people or disabled
  • Refundable Credits: American Opportunity Credit, Additional Child Tax Credit, and credits for federal fuel taxes

This schedule can help expats and students maximize refunds and lower US tax liability.

Specialized Schedules for Certain Tax Cases

1040 Form

Schedule A: Itemized Deductions

Deductions not included in Schedules 1-3 could need to be reported in Schedule A. According to the 1040 Form Instructions Schedule A for 2024, deductions include:

  • Medical and Dental Expenses: Deduct unreimbursed medical expenses exceeding 7.5% of your adjusted gross income (AGI)
  • Taxes Paid: Includes state and local taxes with a limit of $10,000
  • Mortgage Interest: Deduct mortgage interest for a primary or secondary residence
  • Charitable Contributions: Donations to qualified organizations
  • Casualty and Theft Losses: Losses from federally declared disasters

Remember these deductions only make sense if they are larger than your standard deduction, otherwise, this form is not needed.

Schedule B: Interest and Dividends

1040 Form, Schedule B is important for taxpayers with interest or dividends exceeding $1,500 or those with foreign financial accounts. A taxpayer with a foreign financial account must disclose this signature authority on Schedule B.

Schedule C: Business Income (Sole Proprietorships)

Sole proprietors use this schedule to report income or loss from their business. The Form 1040 instructions for tax year 2024 specify to report and calculate business expenses, such as operating costs, supplies, and employee wages on Schedule C.

Schedule D: Capital Gains and Losses

If a taxpayer has to report the sale or exchange of capital assets like stocks, bonds, or real estate, they must file Form 1040, Schedule D. Before filing Form 1040, Schedule D, Form 8949 should be completed.

Schedule E: Rental Income, Royalties, Partnerships, and S Corporations

1040 Form, Schedule E reports income or loss from rental properties, royalties, and business activities. This includes rental income, partnership distributions, and income from estates and trusts.

Schedule F: Farming Income and Expenses

Farmers use this schedule to track any income and expenses related to their profession. In Schedule F, taxpayers must select an accounting method, track business income, and deduct farming-related expenses such as feed, labor, and equipment depreciation.

Schedule H: Household Employment Taxes

If a taxpayer employs a household employee, such as a nanny, housekeeper, or gardener, for $2,700 or more as of this tax year, they must report them on their 1040 Form under Schedule H.

For more details regarding Form 1040, Schedule H, check out the IRS instructions for the 2024 tax year.

Schedule SE: Self-Employment Tax

For taxpayers who are self-employed in the US or abroad, if your net earnings exceed $400, you will be subject to self-employment taxes of 15.3%. This 15.3% is divided into Social Security and Medicare tax.

Schedule 8812: Child Tax Credits

Taxpayers who want to claim up to $1,700 in Additional Child Tax Credit must file Schedule 8812. However, this credit cannot be claimed if you owe US taxes, as you can only claim the excess amount of the Child Tax Credit.

Forms for Expats

Remember, aside from the 1040 Schedules, there are other important forms for expats:

  • Form 2555: The Foreign Earned Income Exclusion, which allows expats to exclude up to $126,500 of foreign earned income
  • Form 1116: The Foreign Tax Credit, which allows expats to use foreign-paid taxes as a credit toward their US tax liability
  • Form 8833: US tax treaty, which is an agreement between countries to help prevent double taxation
