Your Schedule 1, line by line

Schedule 1 (Form 1040), Additional Income and Adjustments to Income, is the attachment for income that doesn't fit on the main 1040 and for above-the-line deductions. Part I totals your additional income on line 10, which carries to Form 1040 line 8. Part II totals your adjustments on line 26, which carries to Form 1040 line 10 and lowers your adjusted gross income.

Anyone with income beyond wages, interest and dividends, or who wants an above-the-line adjustment. That includes self-employment or rental income, unemployment, gambling winnings, prizes, a taxable state refund or crypto income, and deductions like educator expenses, HSA contributions, student loan interest, or half of self-employment tax. If your income is only wages, interest, dividends, retirement or Social Security and you claim no adjustments, you can skip it.

Part I income that isn't on the face of the 1040: a taxable state refund on line 1, alimony from a pre-2019 agreement on line 2, business income from Schedule C on line 3, rental and pass-through income from Schedule E on line 5, farm income from Schedule F on line 6, unemployment on line 7, and a long list of other income on line 8, including gambling winnings, prizes, canceled debt, jury pay and digital asset income.

Adjustments, in Part II, are the above-the-line deductions that lower your adjusted gross income before you choose the standard deduction or itemize. Common ones are educator expenses, health savings account contributions, the deductible half of self-employment tax, self-employed health insurance, IRA contributions and student loan interest. Because they lower AGI, they can also help you qualify for credits that phase out with income.

Yes. Unemployment compensation is fully taxable and reported on Schedule 1, line 7, from the Form 1099-G your state sends. The temporary exclusion of some unemployment from the 2020 pandemic no longer applies, so the full amount counts as income. If you had federal tax withheld from your benefits, that shows on the 1099-G and is credited on your return.

Only if you itemized deductions the year before and deducted state and local income taxes. In that case, some or all of your refund can be taxable this year on line 1, under the tax benefit rule. If you took the standard deduction last year, your state refund is not taxable and does not go on Schedule 1 at all.

They are different forms with different jobs. Schedule 1 is permanent: Part I adds income and Part II lowers your AGI through above-the-line adjustments. Schedule 1-A is new for 2025 through 2028 and holds four deductions created by the One Big Beautiful Bill Act, for tips, overtime, car loan interest and seniors, which lower your taxable income after AGI and flow to Form 1040 line 13b. Despite the similar name, one is not a version of the other, and both can be filed together.

You report all gambling winnings as income on Schedule 1, line 8b, whether or not you received a Form W-2G. Losses are different: you can deduct them only if you itemize on Schedule A, and only up to the amount of winnings you reported. You cannot net losses against winnings on Schedule 1, and you cannot deduct a net gambling loss.

The Part II adjustments are available whether you take the standard deduction or itemize. They include educator expenses up to $300, HSA contributions, the deductible half of self-employment tax, self-employed SEP or SIMPLE and health insurance, the penalty on early withdrawal of savings, traditional IRA contributions, and student loan interest up to $2,500. Each has its own eligibility and limits.

Ordinary income from digital assets, such as crypto you received as payment, mining, staking or airdrops, goes in Part I, line 8, as other income. Simply holding crypto that rose in value is not taxable until you sell, trade or spend it, which is a capital gain reported on Form 8949 and Schedule D instead. Either way, you must answer the digital asset question on the top of Form 1040.

Yes, up to $2,500 of student loan interest on line 21, using the amount from the Form 1098-E your lender sends. You must be legally obligated on the loan, and the deduction phases out at higher modified adjusted gross income. It is an above-the-line adjustment, so you can claim it even if you take the standard deduction.

Traditional IRA contributions can be deductible on line 20, up to the 2025 limit of $7,000, or $8,000 if you are 50 or older, subject to phase-out if you or your spouse have a workplace plan. Roth IRA contributions are never deductible. Health savings account contributions go on line 13 from Form 8889, with 2025 limits of $4,300 self-only and $8,550 family.

The totals flow here. You prepare Schedule C for business income, Schedule E for rental and pass-through income, and Schedule F for farm income first, then the net result carries to Schedule 1, on line 3, line 5 and line 6 respectively. Self-employment income from Schedule C or Schedule F also drives Schedule SE, and the deductible half of that tax comes back as an adjustment on line 15.

It depends on the date of the agreement. For divorce or separation agreements dated on or before December 31, 2018, alimony received is taxable on line 2a and alimony paid is deductible on line 19a. For agreements dated after 2018, alimony is neither taxable to the recipient nor deductible by the payer, so it is not reported on Schedule 1 at all. Child support is never taxable or deductible.

No. The generator helps you fill out and produce a completed Schedule 1 that you can review, attach to your Form 1040, and file. It does not transmit anything to the IRS, and it does not replace tax software, a preparer or the calculations your other schedules need, and it is not tax advice. You are responsible for the accuracy of your figures and for keeping records.
