Schedule 1 provides additional reporting space for income and adjustments that are not generally entered directly on the main Form 1040. The sections that apply depend on the taxpayer’s income sources, deductions, and individual circumstances.

What Is Schedule 1 (Form 1040)?

Schedule 1 (Form 1040) is a supplemental tax schedule used with Form 1040 to report certain additional income and adjustments to income. It helps organize information that may not have a designated line on the main individual income tax return.

Additional income may include certain business income, rental income, unemployment compensation, and other applicable income. Adjustments to income may include certain deductible expenses or other qualifying adjustments.

Who Uses Schedule 1 (Form 1040)?

Schedule 1 (Form 1040) is generally used by individuals who have certain types of additional income or adjustments to income that need to be reported on their federal income tax return.

Not every taxpayer needs to file Schedule 1. Whether it is required depends on the taxpayer’s income, deductions, adjustments, and other circumstances.

What Information Is Needed?

The information needed to complete Schedule 1 depends on the taxpayer’s individual circumstances. Common information may include records of additional income, business income, rental or royalty income, unemployment compensation, deductible expenses, and other applicable adjustments.

Taxpayers may receive information from employers, financial institutions, government agencies, businesses, or other sources. Supporting records should generally be retained for amounts reported on Schedule 1.

How to Fill Out or Complete Schedule 1 (Form 1040)

Schedule 1 is generally completed by identifying the types of additional income and adjustments that apply to the taxpayer. Applicable amounts are entered in the appropriate sections and then combined to determine the totals reported on the taxpayer’s Form 1040.

Only the sections that apply to the taxpayer generally need to be completed. Taxpayers should use their supporting tax documents and financial records to make sure the amounts reported are accurate.

Section 1: Additional Income

The additional income section is generally used to report certain types of income that are not entered directly on Form 1040. Depending on the taxpayer’s circumstances, this may include income from business activities, rental property, partnerships, unemployment compensation, and other applicable sources.

Taxpayers should review their income records to determine whether additional income needs to be reported on Schedule 1. Some types of income may require a separate form or schedule before the amount is transferred to Schedule 1.

Section 2: Business Income

Certain business income may be reported through Schedule 1 when applicable. The amount may come from another schedule used to calculate income or loss from a business activity.

Taxpayers should maintain records of business income and expenses and use the applicable supporting schedule when determining the amount to report. Business owners may have additional filing requirements depending on their type of business and circumstances.

Section 3: Rental, Royalty, Partnership, and Other Income

Certain rental, royalty, partnership, S corporation, estate, trust, and other income may be reported through Schedule 1 when applicable.

The information may come from other tax schedules or statements provided to the taxpayer. Taxpayers should use the applicable supporting documents and avoid reporting the same income more than once.

Section 4: Unemployment Compensation and Other Income

Certain unemployment compensation and other types of income may be reported on Schedule 1 when applicable. The specific types of income that belong in this section depend on the taxpayer’s circumstances and applicable tax rules.

Taxpayers should review income statements and other records to identify amounts that need to be reported. Certain types of income may have separate reporting requirements.

Section 5: Adjustments to Income

The adjustments section is generally used to report certain amounts that may reduce the taxpayer’s income when the applicable requirements are met. Examples may include certain deductible expenses, contributions, or other qualifying adjustments.

The adjustments available to a taxpayer depend on individual circumstances and applicable tax rules. Taxpayers should maintain documentation supporting any adjustment claimed.

Section 6: Other Adjustments

Schedule 1 may also provide space for certain other adjustments that do not fall into the more common categories. These adjustments can vary depending on the taxpayer’s situation.

Taxpayers should review the applicable instructions and supporting documentation before claiming an adjustment. Not every adjustment applies to every taxpayer.

Section 7: Total Additional Income and Adjustments

After applicable amounts have been reported, the totals from the additional income and adjustment sections are generally calculated and transferred to the appropriate portions of Form 1040.

The resulting amounts may affect the taxpayer’s adjusted gross income and overall federal income tax calculation. Taxpayers should review the totals carefully before completing the remainder of their tax return.

Section 8: Review and Filing

Before submitting Schedule 1, taxpayers should compare the information reported on the schedule with their income statements, supporting schedules, receipts, and other tax records.

Schedule 1 is generally filed with the taxpayer’s federal income tax return rather than as a separate standalone return. Any additional schedules or forms required for specific income or adjustments should generally be included with the return.

Common Mistakes

Common Schedule 1 (Form 1040) mistakes may include failing to report additional income, entering incorrect amounts, claiming adjustments that do not apply, or failing to transfer amounts correctly from supporting schedules.

Other issues can include reporting the same income more than once, overlooking required supporting forms, or failing to maintain documentation for adjustments. Reviewing Schedule 1 against the taxpayer’s tax records can help reduce errors.

Related IRS Forms

Schedule 1 (Form 1040) is primarily associated with Form 1040, U.S. Individual Income Tax Return. Other schedules and forms may be used to calculate specific types of income or adjustments before amounts are reported on Schedule 1.
