Why this generator

Built around the two jobs Schedule 1 actually performs

Schedule 1 can look complicated because it brings several unrelated income and deduction categories onto one attachment. The form becomes much easier when Part I and Part II are kept separate.

Part I stays separate from adjustments

Additional income belongs above the dividing line. Adjustments that reduce income belong in Part II.

Only complete the lines that apply

Schedule 1 contains many possible entries, but most taxpayers use only a small number of them.

Related schedules stay connected

Business income can come from Schedule C, rental or K-1 amounts from Schedule E, and farm income from Schedule F.

Totals flow back to Form 1040

Schedule 1 is not a separate return. Its totals become part of your main individual income tax return.

Preview before downloading

Review the schedule before finishing so incorrect or misplaced entries are easier to catch.

Keep the supporting documents

Schedule 1 summarizes amounts that often come from other forms, statements, and your own records.

Interactive guide

What goes on Form 1040 Schedule 1?

Schedule 1 is split into Additional Income and Adjustments to Income. These are common categories you may see while completing the form.

Part I

Business income or loss

Sole-proprietor business profit or loss from Schedule C is reported through Schedule 1.

Part I

Rental, royalty and K-1 income

Applicable amounts from Schedule E feed into the additional-income section.

Part I

Other gains or losses

Certain gains or losses reported on Form 4797 can flow through this schedule.

Part I

Unemployment compensation

Taxable unemployment compensation is included with other applicable additional-income items.

Part II

Self-employed adjustments

Applicable deductions can include the deductible part of self-employment tax, qualifying retirement contributions, and qualifying self-employed health insurance.

Part II

HSA and IRA deductions

Eligible health savings account and traditional IRA deductions are included among Schedule 1 adjustments.

Part II

Educator expenses

Eligible educator expenses are reported as an adjustment rather than as an itemized deduction.

Part II

Student loan interest

An eligible student loan interest deduction is another adjustment that can appear in Part II.

Line by line

Every 2025 Schedule 1 line, and where the number comes from

Most of Schedule 1 is a landing spot for totals figured somewhere else. Here's what each line takes and the form or limit behind it.

The basics

What is Schedule 1?

Form 1040 attachment

Schedule 1, Additional Income and Adjustments to Income, is used with Form 1040 when you have income or deductions the main return doesn't have room for. Most people who file it have one of a few triggers: self-employment, a rental, unemployment, gambling winnings, an HSA or IRA contribution, or student loan interest. If none of those apply, you probably don't need it.

Part I

Part I collects additional income on lines 1 to 9, totaled on line 10 and carried to Form 1040, line 8. Many of these lines are just totals from another form, so finish Schedule C, E, F or Form 4797 first. A loss is entered as a negative number and reduces your total income.

Part II

Part II collects adjustments to income on lines 11 to 25, totaled on line 26 and carried to Form 1040, line 10. They're called above-the-line deductions because they come off before adjusted gross income, so you get them whether you itemize or take the standard deduction, and a lower AGI can unlock other credits and deductions.

For tax year 2025

What changed on and around Schedule 1

The 2025 law added new deductions, but they don't live on Schedule 1. Here's what moved, what stayed, and the 2025 numbers that matter.

Schedule 1-A is separate

The new deductions skip Schedule 1. No tax on tips, overtime, car loan interest and the senior deduction go on Schedule 1-A and Form 1040, line 13b. They cut taxable income, but they don't lower AGI the way Schedule 1 adjustments do.

Moving expenses

Still Armed Forces only. The moving expense deduction on line 14 stays limited to active-duty members moving under orders, and the 2025 law made that limit permanent instead of letting it expire.

2025 limits

Higher caps for 2025. HSA $4,300 self-only and $8,550 family; IRA $7,000, or $8,000 at 50 or older; student loan interest phase-out from $85,000 MAGI ($170,000 joint); educator expenses $300.

How it flows

From supporting forms to Schedule 1 and then to your 1040

Schedule 1 often acts as the bridge between another tax schedule and the main Form 1040.

1

Start with the source

Use the statement, schedule, form, or records that establish the income or deduction.

2

Put it on the correct Schedule 1 line

Additional income goes in Part I. Adjustments go in Part II.

3

Total the applicable entries

Schedule 1 combines the amounts before transferring its totals to the main return.

4

Attach it to Form 1040

Schedule 1 travels with the individual return rather than being filed as a standalone tax return.

Try it

Estimate your Schedule 1 totals and AGI

Enter your income and adjustments. The tool figures the deductible half of self-employment tax, applies the 2025 student loan interest phase-out, and shows lines 10 and 26 and your adjusted gross income.

Filing status W-2 wages, Form 1040 line 1z ($) Other 1040 income, lines 2 to 7 ($) Schedule C or F net profit ($) Other Part I income, lines 1, 2a, 4, 5, 7, 9 ($) Other adjustments: HSA, IRA, SEP, health insurance ($) Student loan interest paid in 2025 ($)

A quick estimate, not tax advice. Losses aren't modeled, so enter zero for a loss. MAGI for student loan interest is treated as AGI before that deduction, which is right for most filers but ignores foreign income exclusions. Enter IRA and HSA amounts you've already confirmed are deductible.

Your 2025 Schedule 1, roughly

Line 10, additional income$60,000.00

Line 15, half of SE tax$4,238.87

Line 21, student loan interest$2,000.00

Line 26, total adjustments$10,538.87

Form 1040 line 9, total income$60,000.00

Form 1040 line 11a, AGI$49,461.13

An estimate to plan with, not a filed return. The Schedule 1 generator builds the full schedule, and IRS Publication 970 covers the student loan interest worksheet.

Worked examples

Five 2025 Schedule 1 scenarios, with the numbers

How common situations land on Schedule 1 and what they do to adjusted gross income.

Filer	What they report	Schedule 1	Result
Single freelancer	Schedule C profit $60,000; HSA $4,300; student loan interest $2,000	L10 $60,000.00 L26 $10,538.87	Half SE tax $4,238.87 plus HSA plus full $2,000 interest; AGI $49,461.13
Married couple, side business	Wages $150,000; Schedule C profit $20,000; student loan interest $2,500	L10 $20,000.00 L26 $3,912.96	Half SE tax of $1,412.96 keeps MAGI at $168,587.04, under $170,000, so the full $2,500 counts; AGI $166,087.04
Single, in the phase-out	Wages $91,000; student loan interest $2,500	L21 $1,500.00	MAGI is $6,000 into the $15,000 range, so 40% of $2,500 is lost; AGI $89,500
Laid off mid-year	Wages $38,000; unemployment $8,000	L7 and L10 $8,000.00	Unemployment is fully taxable; total income and AGI $46,000
Casino jackpot	Form W-2G winnings $5,000; losses $3,000	L8b $5,000.00	All $5,000 is income here; the $3,000 of losses only count as an itemized deduction on Schedule A

Rows 1 to 4 match the estimator above. Self-employment tax is 15.3 percent of 92.35 percent of profit, and half of it goes on line 15. In row 2, the couple's wages leave $26,100 of room under the $176,100 Social Security wage base, more than their $18,470 of self-employment earnings, so the full 12.4 percent applies.

Run your own numbers

Try the estimator, then build the schedule in the Schedule 1 generator. Business profit starts on the Schedule C generator, and tips or overtime belong on the Schedule 1-A generator.

Avoid these

Common Schedule 1 mistakes

Most errors come from putting an amount in the wrong part, forgetting a supporting form, or treating Schedule 1 like a standalone return.

Mixing Schedule 1 with Schedule 1-A

They're different schedules. Schedule 1 covers additional income and adjustments to income. Schedule 1-A holds the new tips, overtime, car loan interest and senior deductions, which don't reduce AGI.

Entering gross business receipts directly

Business activity generally needs to be calculated on its supporting business schedule before the resulting amount reaches Schedule 1.

Skipping supporting schedules

A Schedule 1 line can depend on Schedule C, Schedule E, Schedule F, Form 4797, or another supporting form.

Putting an adjustment in Part I

Deductions that qualify as adjustments belong in Part II, not in the additional-income section.

Deducting employer HSA money again

Employer and pretax payroll contributions, shown in W-2 box 12 with code W, are already excluded from your wages. Only contributions you made yourself with after-tax money go on line 13.

Netting gambling losses

Report the full winnings on line 8b. Losses can't be subtracted here; they're deductible only on Schedule A if you itemize, and only up to your winnings.

Filing it

How to use Schedule 1 with your tax return

Schedule 1 is completed as part of your individual return and attached to Form 1040 when required.

1

Complete the supporting forms

Finish any schedules or forms that supply amounts to Schedule 1.

2

Complete Schedule 1

Enter the applicable additional income and adjustments and review the totals.

3

Attach it to your 1040

Include Schedule 1 with the rest of your individual tax return when you file.

2025 deadlines

Schedule 1 is due with your Form 1040. The 2025 return was due April 15, 2026, and an extension on Form 4868 moves filing to Thursday, October 15, 2026. The extension doesn't extend the time to pay. IRS Free File stays open through October 15 for 2025 AGI of $89,000 or less, and Free File Fillable Forms work at any income. IRS Direct File isn't available for the 2026 filing season.

Where this tool fits

This generator helps you enter and review information for Schedule 1 and produce a completed schedule. It doesn't transmit your return to the IRS and isn't a substitute for tax software or professional tax advice. You're responsible for your figures and the records behind them.

FAQ

Schedule 1 questions, answered plainly

Schedule 1, Additional Income and Adjustments to Income, is an attachment to Form 1040. Part I reports income that doesn't have its own line on the 1040, like business profit, rentals, unemployment and gambling winnings. Part II reports adjustments, the above-the-line deductions that lower your adjusted gross income.

Only if you have an item that belongs on it. If your income is just wages, interest, dividends, retirement income and Social Security, and you don't claim an adjustment like student loan interest or an HSA deduction, you can file Form 1040 without Schedule 1.

Part I is additional income: taxable state refunds (line 1), pre-2019 alimony received (2a), Schedule C business income (3), Form 4797 gains (4), Schedule E income (5), Schedule F farm income (6), unemployment (7), and other income on lines 8a to 8z, such as gambling, canceled debt, jury duty pay, prizes and digital assets. Line 10 totals it and goes to Form 1040, line 8.

Part II is adjustments to income: educator expenses, HSA contributions, Armed Forces moving expenses, half of self-employment tax, self-employed retirement plans and health insurance, early withdrawal penalties, pre-2019 alimony paid, IRA contributions, student loan interest and a list of other adjustments on lines 24a to 24z. Line 26 totals them and goes to Form 1040, line 10.

For 2025, line 10 of Schedule 1 goes to Form 1040, line 8, and becomes part of total income on line 9. Line 26 goes to Form 1040, line 10, and is subtracted to get adjusted gross income on line 11a.

No. Schedule 1-A is new for 2025 and holds the deductions for qualified tips, overtime, car loan interest and the extra deduction for seniors. Those go to Form 1040, line 13b, after AGI, so they lower taxable income but not AGI. Schedule 1 adjustments lower AGI itself, which can help with other AGI-based limits.

Up to $2,500 of interest paid on a qualified student loan. The deduction phases out between $85,000 and $100,000 of modified AGI, or $170,000 and $200,000 on a joint return, and it isn't available if you're married filing separately or can be claimed as someone's dependent. Form 1098-E shows the interest you paid.

Twice. Your Schedule C or F profit goes on line 3 or 6 as income, and half of the self-employment tax from Schedule SE goes on line 15 as an adjustment. With $60,000 of profit, self-employment tax is $8,477.73, so line 15 is $4,238.87.

Yes, for contributions you made yourself, figured on Form 8889 and entered on line 13. For 2025 the limits are $4,300 for self-only coverage and $8,550 for family coverage, plus $1,000 if you're 55 or older. Contributions through your employer or payroll are already excluded from wages, so don't deduct them again.

Yes. All unemployment compensation is taxable for 2025 and goes on line 7 from Form 1099-G, box 1. If you didn't have tax withheld, you may owe when you file.

On line 8b, in full, using the amounts on any Form W-2G plus winnings that didn't come with a form. You can't subtract losses on Schedule 1; gambling losses are an itemized deduction on Schedule A, limited to your winnings.

Eligible educators, kindergarten through grade 12 teachers, instructors, counselors, principals and aides who work at least 900 hours a school year, can deduct up to $300 of unreimbursed classroom costs for 2025. If you're both educators filing jointly, the limit is $600, but no more than $300 each.

Yes. The net profit or loss on Schedule C, line 31, goes to Schedule 1, line 3, and the same profit drives self-employment tax on Schedule SE, half of which comes back as the line 15 adjustment.

Yes. The total on Schedule E, line 41, from rentals, royalties, partnerships, S corporations, estates and trusts, goes to Schedule 1, line 5.

Schedule 1 is filed with your Form 1040, so it follows the same dates. The 2025 return was due April 15, 2026, and an extension on Form 4868 moves the filing deadline to Thursday, October 15, 2026. Tax owed was still due in April.

No. Schedule 1 is attached to Form 1040 or 1040-SR, along with any schedule or form that feeds it, such as Schedule C, Schedule SE or Form 8889.

No. It helps you prepare, review and download a completed Schedule 1. It doesn't transmit anything to the IRS, it isn't tax software or tax advice, and you're responsible for the accuracy of your figures.
