IRS Tax Filing Your First U.S. Tax Return
Filing your first U.S. tax return in 2026 can feel like entering a new world of acronyms and paperwork. Whether you are a recent graduate starting your first job, a new H-1B professional, or an international student on OPT, the 2025 tax year (which you file in 2026) is unique due to the sweeping changes from the One, Big, Beautiful Bill Act (OBBBA).
Here is everything a first-time filer needs to know to navigate the system successfully.
Do You Actually Need to File?
For the 2026 filing season, you generally must file a 2025 tax return if your Gross Income exceeds these thresholds:
- Single Filers: $15,750
- Married Filing Jointly: $31,500
- Self-Employed: If you earned $400 or more in “gig” or freelance work.
The “Refund” Exception: Even if you earned less than the threshold, you should file if your employer withheld federal tax from your paycheck. The only way to get that money back is by filing a return.
The First-Timer’s “AGI Trick”
To e-file your tax return, the IRS uses your Prior Year Adjusted Gross Income (AGI) as a digital signature to verify your identity.
- The Problem: As a first-time filer, you don’t have a 2024 tax return.
- The Solution: When the software asks for your 2024 AGI, enter “0” (zero). This tells the IRS system that you are a new filer, allowing your electronic submission to be accepted.
Essential Documents Checklist
Before you start, gather these key items:
- Identification: Your Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN).
- Income (W-2s & 1099s): Your employer(s) should have sent these by Jan 31.
- New for 2026 (Trump Accounts): If you opened one of the new Trump Accounts for a child born in 2025, gather the contribution records to ensure the $1,000 pilot credit is correctly applied.
- Bank Info: Routing and account numbers. In 2026, the IRS is phasing out paper checks; you must use direct deposit for a fast refund.
New 2026 Deductions You Shouldn’t Miss
The OBBBA has introduced “Working Family” cuts that are perfect for first-time filers:
- No Tax on Overtime: If you worked extra hours in 2025, you can deduct the “premium” portion of your overtime pay (up to $12,500).
- No Tax on Tips: If you work in a service industry, you can deduct up to $25,000 in qualified cash tips from your taxable income.
- Car Loan Deduction: If you bought a new, U.S.-made car in 2025, you can deduct up to $10,000 in loan interest.
- Special Note for International Newcomers (H-1B/F-1)
- Residency Test: If you arrived in the U.S. mid-2025, use the Substantial Presence Test to see if you file as a “Resident” (Form 1040) or “Non-Resident” (Form 1040-NR).
- FICA Taxes: Unlike F-1 students, H-1B workers must pay Social Security and Medicare taxes. If your employer didn’t withhold them, you may need to resolve this on your first return.
