Everything a first-time filer needs to know: required documents, step-by-step filing process, available tax credits, and common mistakes to avoid.
Filing taxes for the first time can feel overwhelming, but the process is straightforward once you understand the basics. This guide covers everything a first-time filer needs, including when you must file, which documents to gather, how to choose a filing service, and the tax credits you should know about.
For a step-by-step walkthrough, see our How to File Taxes for Free guide. For help with forms, visit our IRS Tax Forms Guide.
Do You Need to File?
For 2025, you must file a federal tax return if your gross income exceeds: $15,000 for single filers, $30,000 for married filing jointly, $22,500 for head of household, or $5 if you are married filing separately. Even if you earned less, you should file if your employer withheld federal income tax from your paychecks because you will get that money back as a refund. Also file if you qualify for refundable credits like the EITC. Use our Tax Refund Calculator to estimate what you might get back.
Documents You Need
- Your Social Security card or ITIN letter
- W-2 form(s) from each employer you worked for
- 1099 forms if you did freelance, gig, or contract work
- 1098-T if you paid college tuition (for education credits)
- 1098-E if you paid student loan interest
- Your bank account and routing number for direct deposit
- Last year's tax return (if you filed)
- Photo ID (driver's license or passport)

Tax Credits for First-Time Filers
Tax credits are better than deductions because they reduce your tax bill dollar for dollar. Key credits for first-time filers: Earned Income Tax Credit (up to $7,830 for eligible low-to-moderate income workers), American Opportunity Tax Credit (up to $2,500 for college tuition and expenses), Lifetime Learning Credit (up to $2,000 per return), and the Saver's Credit (for retirement contributions). See our EITC Guide and Child Tax Credit Guide for more details.
Common Mistakes to Avoid
First-time filers often: forget to sign and date their return, enter incorrect Social Security numbers, transpose bank account numbers for direct deposit, miss available credits and deductions, or file under the wrong filing status. Always double-check your name, SSN, and bank details before submitting. Most free filing services include a review checklist to catch errors.
