Understanding Schedule 1

Form 1040 is the main form; the schedules and other forms are just there to support or report what you cannot add in Form 1040.

This form states additional income types that are not included on Form 1040, along with some additional adjustments to income.

Who Needs to File IRS Form 1040 Schedule 1?

Not everyone is required to attach Schedule 1 to their federal income tax return. The IRS has shortened and simplified the old Form 1040. It enabled individuals to include forms as per the requirement.

You are only required to file Schedule 1 if you receive any of the additional income types or adjustments, which we will discuss further in the blog.

What are Above the Line Deductions?

Before the IRS and the Treasury redesigned IRS Form 1040 in 2018, it comprised several lines to report various types of income. It also included a line for "Other Income". Additionally, it consisted of numerous lines for making adjustments to income, also called "above-the-line" deductions.

Now, in the latest version, taxpayers get a lot of lines reporting the most common income types. It can include:

  • wages
  • Retirement income
  • Interest and dividends
  • Social Security benefits
  • Capital gains or losses

Remember that the requirement to report any other type of income and adjustments to income has not disappeared. Instead, the reporting requirements have shifted to Schedule 1. 

Update Schedule 1 Starting in 2024 

When Congress reduced the reporting thresholds for issuing Form 1099-K, Schedule 1 was updated to add a new section. It was added to simplify entering those amounts that don't affect your taxable income. It includes amounts added on a 1099-K reported in error.

For Example

The transfer of personal money and the sale of personal items at a loss, and hence they are neither taxable nor deductible. 

Additionally, imposed in 2024 in line 8v in Section 1 for reporting digital assets acquired as ordinary income that aren't reported anywhere else on your tax return. It can include income received from forks, staking, or mining, which aren't wages on line 1a, or capital gain or loss reported on Form 8949 and Schedule D. 

Part I - Additional Income 

You will use part I of Schedule 1 to report the following income types:

  • Farm income or loss
  • Rent and royalty income 
  • Unemployment compensation
  • Income or loss acquired from a business
  • Taxable refunds of state and local income taxes
  • Gains or losses from sales of a business property
  • Income from a partnership, S corporation, or trust
  • Alimony received (for divorce agreements dated before the 31st of December 2018). 

Now, line 8 of Schedule 1 is the comprehensive for other income types that are unsuitable for the predefined lines. Such as prizes, awards, or winnings from gambling.

When you navigate down to the Schedule 1 lines, you may find that some of the items also need an additional form or schedule. For example, you will be required to attach Schedule C to your return in case you acquire profit or loss from a business. 

Also, you will have to attach Schedule E if you want to report rent and royalties as income. After you have filled out all your various income types on Schedule 1. Then, the aggregate is transferred to line 8 of Form 1040. 

Point to Note:

If you receive all your income from the five categories mentioned on Form 1040, you don't need to use Schedule 1. The five categories are wages, interest, and dividends, retirement income, social security benefits, and capital gains or losses. 

Part II - Adjustments to Income 

Part II of Schedule 1 includes adjustments to income, including:

  • IRA contribution deduction
  • penalties for early withdrawals of savings
  • the deductible part of self-employment taxes
  • contributions to health savings accounts (HSAs)
  • up to $2,500 of deductible student loan interest
  • moving expenses for the members of the Armed Forces
  • health insurance premiums for self-employed people
  • contributions to a SEP, SIMPLE, or qualified retirement plan
  • alimony payments (for divorce agreements dated before the 31st of December, 2018)
  • nearly $300 in 2025 of unreimbursed expenses for educators working in schools
  • unreimbursed business expenses of military reservists, performing artists, and fee-based government staff (the only qualifying professions for specific business deductions). 

These deductions can be valuable for several taxpayers for mainly two reasons. Firstly, these deductions reduce your adjusted gross income directly. It helps in uncovering the possibility of claiming other deductions and getting tax credits that have adjusted gross income limits.

Example

If you wish to claim the full American Opportunity Tax Credit. Then, your modified adjusted income for 2025 must be $80,000 or below ($160,000 or less if you are married filing jointly). Also, if your modified adjusted gross income is above $90,000 ($180,000 for joint filers), you can't claim the credit. 

Suppose you have an income of $91,000. However, you decided to contribute $3,000 to your health savings account, $8,000 to a SEP IRA. Also, paid a student loan interest, which added up $1,000. 

Now, with a total of $12,000 in above-the-line deductions, your adjusted gross income would be $79,000. It means that you are probably eligible to claim the full American Opportunity Tax Credit. 

Secondly, Schedule 1 adjustments to income are also valuable, as you are not required to itemize deductions to claim them. Above-the-line deductions help in lowering your income before applying either the Standard Deduction or itemized deductions.

Almost 90% of the taxpayers choose the standard deduction. However, above-the-line deductions are a helpful tax break that can be achieved by avoiding the extra paperwork of itemizing. 

The Bottom Line 

Schedule 1 Form 1040 is vital for those who have additional income sources and wish to claim adjustments to lower their taxability. It is an essential part of your tax return as it covers income and deductions that are stated directly on Form 1040. This form ensures that all income and adjustments are reported properly to the IRS.

Schedule 1 is an attachment to Form 1040, used to report types of income that are not directly listed on the main Form. It includes business income, rental income, unemployment compensation, and taxable refunds. It also enables taxpayers to claim certain "above-the-line" deductions like IRA contributions or student loan interest.

You need to file Schedule 1 if you have additional income sources apart from wages, interest, dividends, and social security benefits. It includes freelancers, small business owners, landlords, and anyone reporting unemployment income or claiming specific deductions.

Schedule 1 reports additional income, such as:

  • Farm income
  • Winnings from gambling
