Taxes can feel like a puzzle, but breaking it down with the financial experts of AcctRight makes it manageable. According to the IRS, the Schedule 1 Form 1040, sometimes called the Schedule 1 tax form, is used to report additional types of income and adjustments.

We’ll cover what Schedule 1 is, who needs it, how to fill it out, and even some tips to make filing smoother. By the end, you’ll feel confident handling your 1040 Schedule 1 or know when to reach out to our team for help.

What Is Schedule 1 Form 1040?

So, what is IRS Schedule 1 exactly? In simple terms, Schedule 1 on 1040 is an attachment to your main Form 1040, 1040-SR (for seniors (age 65 or older)), or 1040-NR (for non-residents) that handles additional income and adjustments to income. It’s not for everyone, but if you have side gigs, rental properties, or certain deductions, it’s essential. The form splits into two parts:

Part I: Additional Income:

You’ll use Schedule 1 if you received:

• Business income (reported from Schedule C)
• Rental income or royalties (from Schedule E)
• Unemployment compensation
• Prize or award money
• Gambling winnings
• Farm income

Part II: Adjustments to Income:

Part II of Schedule 1 focuses on adjustments to income, which can help reduce your adjusted gross income (AGI). These include:

• Educator expenses
• Student loan interest deductions
• Self-employment tax deductions
• IRA contributions
• Health savings account (HSA) deductions
• Moving expenses for active-duty military members

Why does this matter? Your AGI affects eligibility for credits, deductions, and even things like student aid. Missing Schedule 1 taxes could mean overpaying or facing penalties. For instance, if you’re self-employed, reporting Schedule 1 business income here ties into your overall return.

Who Needs to File Schedule 1?

Not everyone needs to file Schedule 1 (Form 1040). You must file it if you have any additional income or deductions not listed directly on your Form 1040, such as freelancing or self-employment income, rental income, business profit or loss, farm income, or unemployment compensation.

You Likely Need it if:

• You have additional income from Schedule 1 Line 10, like taxable refunds from state taxes, alimony received (for pre-2019 agreements), or prizes and awards.
• You’re self-employed with business income or loss from Schedule C.
• You earned from rentals, royalties, or partnerships via Schedule E.
• Farm income? That’s Schedule F territory.
• Other extras: Gambling winnings, cancellation of debt, or even Alaska Permanent Fund dividends.

On the Adjustments Side:

• Teachers claiming educator expenses.
• Reservists or artists with certain business costs.
• Deductions for health savings account (HSA) contributions, IRA deduction, or student loan interest.

If all your income is from wages, interest, dividends, retirement, or Social Security (as listed on Form 1040), skip it.

Note:

If you’re an expat or earn foreign income, remember to use Form 2555 to calculate what’s excluded before reporting the rest on Schedule 1. Don’t list the excluded amount as a negative number; just make sure you only report taxable income to avoid double-counting.

How to Fill Out Schedule 1: Step-by-Step Instructions

Filling out Schedule 1 instructions doesn’t have to be daunting. Grab your docs and follow along.

1. Gather Documents: W-2s, 1099s (like 1099-NEC for freelance), state refund notices, and supporting forms (Schedule C, E, etc.).
2. Start with Part I: Enter amounts line by line. For Schedule 1 Lines 3+6, pull from attached schedules, Line 3 for business, Line 6 for farms.
3. Move to Part II: Claim adjustments with proof, like loan statements for Line 21.
4. Total and Transfer: Calculate Lines 10 and 26, then plug into Form 1040.
5. Attach and Review: Include with your return. Use software for auto-calcs.

The calculated amount on Form 4797 is transferred to Schedule 1, impacting your total income on Form 1040. Learn more in our detailed guide on IRS Form 4797 Instructions.

Common Mistakes to Avoid When Filing Schedule 1

These errors are common in many filings, but they’re completely avoidable with proper attention and understanding.

• Forgetting Attachments: No Schedule C for business income? Your return gets rejected.
• Wrong Alimony Dates: Mismatch on Lines 2b/19c triggers audits.
• Math Errors: Double-check additions, software helps, but verify.
• Misreporting Foreign Income: Expats, note that Form 2555 must be reported as negative.
• Overlooking Adjustments: Missing student loan interest costs refunds.
• Not Updating for Changes: With 2025’s new rules, old habits bite.
