If you earned money outside your regular job, or paid for things like classroom supplies or student loans – you might need Schedule 1. It’s the IRS form where you report “extra income” and claim certain deductions that lower your taxable income.
Think of it as the place where side hustles, unemployment pay, and teacher expenses all get accounted for so your taxes reflect your real situation.
What is Schedule 1?
You’ll likely need Schedule 1 if any of the following apply:
- You worked as a freelancer or gig worker and earned money not shown on a W2.
- You received unemployment benefits during the year.
- You made money from renting property or running a small business.
- You paid student loan interest or educator expenses (like classroom supplies).
- You contributed to a retirement plan or health savings account on your own.
If you only earned regular wages from an employer and didn’t have any of the above, you probably don’t need Schedule 1.
Common Types of Income Reported
Here are the most frequent kinds of “extra income” people include on Schedule 1:
- Unemployment benefits
- Freelance or side-gig income (for example, rideshare driving or online consulting)
- Rental or royalty income
- Prize or award money
- Business income from self-employment
Example:
Jamie earned $52,000 from a full-time job and another $4,000 from weekend freelance design work. Jamie reports the $4,000 on Schedule 1 so the IRS sees the total income accurately.
Common Adjustments You Can Claim
“Adjustments” are expenses that lower your taxable income, even if you don’t itemize deductions. They’re a simple way to make sure you’re only taxed on what you actually earned after key expenses.
Teachers can deduct up to $300 for classroom supplies they buy out of pocket (or up to $600 if both spouses qualify). It’s a small but meaningful way to get credit for what you spend to support your students.
If you paid interest on student loans, you can usually deduct up to $2,500, as long as your income falls within IRS limits. That helps reduce your taxable income, even if you don’t itemize.
Self-employed workers get several breaks too. Contributions to retirement plans like a SEP or SIMPLE IRA count as deductions, helping you save for the future and lower your current taxes.
Finally, if you pay for your own health insurance, you may be able to deduct those premiums as well; especially if you’re self-employed and not eligible for an employer plan.
Example:
Taylor, a kindergarten teacher, spent $275 of her own money on classroom materials. She can deduct that amount on Schedule 1 to lower her taxable income.
How to Fill Out Schedule 1
1) Gather your records. Collect W2s, 1099s, unemployment statements, and receipts for deductible expenses.
2) Enter your extra income. List any earnings that didn’t come from your employer.
3) Add your adjustments. Include deductions for education costs, retirement savings, or other qualified expenses.
4) Transfer totals to Form 1040. Your adjusted gross income will automatically reflect these changes.
You’ll submit Schedule 1 together with your main Form 1040 when you file your tax return.
Filing Deadlines
For 2025 income, your federal tax return, including Schedule 1, is due April 15th, 2026.
If you request an extension, you’ll have until October 15th, 2026 to file your return.
Keep in mind that an extension to file does not extend your time to pay any taxes owed — payments are still due by April 15th, 2026 to avoid penalties and interest.
Why Schedule 1 Matters (and How to Get It Right)
Filling out Schedule 1 isn’t just another IRS checkbox; it’s how you make sure your taxes reflect your real financial life. When completed accurately, it helps you report all your income, claim valuable deductions, and calculate your adjusted gross income (AGI) correctly. That number affects almost everything else on your return, from credits and refunds to next year’s tax planning.
Think of Schedule 1 as a quiet multitasker: it captures side jobs, unemployment benefits, classroom expenses, and student loan interest, all in one place. When you take the time to fill it out properly, you’re not just staying compliant; you’re also giving yourself the best chance to lower your overall tax bill.
Common Mistakes to Watch For
Many people skip Schedule 1 simply because they think it doesn’t apply to them. Others forget to include gig earnings, student loan interest, or teacher expenses. The result? Missed deductions and a smaller refund than you deserve.
A quick review before you file can prevent those errors. Double-check that every extra income source and deductible expense made it onto your return. A few minutes of attention here can save hours of stress later, and may even put more money back in your pocket.
