Your First US Tax Return: W-2 and 1099, Step by Step
A practical walkthrough for your first US tax return, whether you are an employee, a contractor, or both.
In short: To file your first US tax return, gather your income forms (a W-2 from each employer, a 1099-NEC if you did contract work), confirm whether you file Form 1040 as a resident or Form 1040-NR as a nonresident, and e-file with direct deposit by April 15. The IRS issues most e-filed refunds within 21 days; refunds that include the EITC or the refundable Child Tax Credit are held until at least mid-February.
W-2 or 1099-NEC: what's the difference?
Both forms report what you earned, but they describe two different working relationships. A W-2 means you were an employee and your employer withheld tax from every paycheck. A 1099-NEC means you were an independent contractor: you were paid in full and the tax is entirely on you.
| W-2 (employee) | 1099-NEC (contractor) | |
|---|---|---|
| Who withholds tax? | Your employer, every paycheck | Nobody. You pay it. |
| Social Security and Medicare | You pay 7.65%, employer matches | You pay the full 15.3% self-employment tax |
| Expenses | Generally not deductible | Business expenses reduce your profit |
| Extra schedules | Usually none | Schedule C and Schedule SE |
| Payments during the year | Usually not needed | Estimated tax if you expect to owe $1,000 or more |
A very common pattern for new arrivals: a salaried day job plus evening delivery or rideshare work. You'll get a W-2 from the job, possibly a 1099 from the app, and you report both on one return.
Watch out: for payments made after December 31, 2025, the threshold that requires a business to send you a 1099-NEC rose to $2,000 (it was $600). That threshold is about the payer's paperwork, not your obligation. You report all self-employment income, whether or not a form arrives.
Reading a W-2 in two minutes
- Box 1: wages subject to federal income tax. It can be lower than your gross pay if you contribute pre-tax to retirement or health insurance.
- Box 2: federal income tax actually withheld, the number that gets compared with your real tax to produce a refund or a balance due.
- Boxes 3 to 6: Social Security and Medicare wages and the tax withheld on them.
- Boxes 15 to 17: state wages and tax, needed for your state return.
First, check that the name and SSN at the top match your card. A one-letter difference can slow processing, and only the employer can issue a corrected form.
How does your W-4 shape your return?
The W-4 you fill out on day one tells your employer how much to withhold. Withhold too little and you owe in April; withhold too much and you get it back as a refund.
A big refund isn't a bonus. It's your own money, lent to the government interest-free. The IRS Tax Withholding Estimator takes about 25 minutes and produces a pre-filled W-4 to hand your employer. Update it after marriage, a new baby, a second job, or when both spouses start working. Nonresidents can't use the estimator and follow Notice 1392 instead.
Form 1040 or 1040-NR?
The form follows your tax status, not your visa label. Green card holders and anyone who meets the substantial presence test file Form 1040. Nonresidents with US income file Form 1040-NR.
If you arrived on an immigrant visa mid-year, you probably have a dual-status year with special rules. If your spouse is a citizen or resident, you may be able to elect resident treatment and file jointly. Our US taxes guide explains both tests.
Documents checklist
- Photo ID for you and your spouse if filing jointly.
- Social Security cards for everyone on the return, or the ITIN letter for anyone without an SSN.
- Dates of birth for everyone listed.
- Every W-2 from every employer, including short jobs.
- Any 1099-NEC or 1099-K, your own records of gig income, and expense receipts.
- Bank interest statements (1099-INT), if any.
- Form 1095-A if you bought coverage on the Marketplace (see our open enrollment guide).
- Childcare provider's name, tax ID and amount paid.
- Bank routing and account numbers for direct deposit.
- Last year's return, if you have one.
If you're a resident with income from back home, add those records and proof of any foreign tax you paid.
Step-by-step: filing your first return
- Confirm your tax status: resident, nonresident, or dual-status.
- Pick a filing status: single, married filing jointly, married filing separately, or head of household. Head of household carries a bigger standard deduction but strict rules.
- Choose how to file: free VITA help, IRS Free File, or a paid preparer with a PTIN.
- Enter all income, not only what arrived on a form.
- Figure self-employment tax on Schedule SE if your net profit was $400 or more.
- Claim the credits you qualify for, such as the Child Tax Credit and EITC (see our family credits guide).
- Choose direct deposit: the IRS began phasing out paper refund checks on September 30, 2025.
- Check names and numbers character by character, then sign and e-file.
- Keep a copy of the return and all documents for several years.
A hypothetical example
Ahmed arrived from Alexandria with a green card in 2025. He works at a warehouse (W-2) and drives for a delivery app in the evenings, netting $8,000 after car expenses. He files Form 1040 as a resident, adds Schedule C for the delivery business and Schedule SE for self-employment tax, which comes to roughly 15.3% of net profit after a small adjustment on the form: somewhere around $1,100, on top of regular income tax. A mileage log kept all year would have made that profit figure more accurate.
When will your refund arrive?
| Situation | Typical timing, per the IRS |
|---|---|
| E-filed with direct deposit | Most within 21 days |
| Paper return by mail | 6 weeks or more after the IRS receives it |
| Return claiming EITC or the Additional Child Tax Credit | Held until at least mid-February; in the 2026 season the IRS expected most by March 2, 2026 |
| Amended return (1040-X) | Longer, since both returns are compared |
Track it with Where's My Refund 24 hours after e-filing or 4 weeks after mailing, or call 800-829-1954.
What if your W-2 is missing or wrong?
Employers generally provide W-2s by January 31. If yours is missing or incorrect, contact the employer first. If it still hasn't been fixed by the end of February, call the IRS at 800-829-1040 with your details and the employer's name, address and EIN if you have it.
If the deadline is close, you can file using Form 4852, a substitute where you estimate wages and withholding from your last paystub. If the real W-2 arrives later with different numbers, file an amended return on Form 1040-X.
What if you owe?
File on time even if you can't pay in full; not filing is worse than not paying. Form 4868 extends the filing deadline to October 15, but payment is still due April 15. With significant gig income you'll likely need quarterly estimated payments on Form 1040-ES next year if you expect to owe $1,000 or more.
Common first-return mistakes
- Forgetting a short job: the IRS gets a copy of every W-2, and a missing one triggers a letter later.
- Ignoring small app income: no 1099 doesn't mean no tax.
- Claiming head of household without meeting the rules: it can lead to an IRS letter and a tax adjustment.
- Wrong bank numbers: check twice, since paper checks are no longer the default.
- Signing a blank return or letting a preparer route your refund to their account.
- Answering texts "from the IRS": the IRS doesn't start contact by text or social media to ask for personal information. See how to spot real IRS letters.
What next?
- After acceptance, save the e-file confirmation and a PDF of the return.
- Adjust your W-4 if your refund or balance due was large.
- Start a monthly log of gig income and expenses.
- Family member without an SSN? Apply for an ITIN with your next return.
Frequently asked questions
What is the difference between a W-2 and a 1099-NEC?
A W-2 goes to employees whose employer withheld tax from each paycheck. A 1099-NEC goes to independent contractors who were paid in full and pay their own tax, including self-employment tax.
I did not get a 1099 from the app. Do I still report the income?
Yes. All self-employment income is reportable with or without a form. The 1099-NEC threshold rose to $2,000 for payments after December 31, 2025, but that rule is about the payer.
How long does a refund take?
The IRS issues most e-filed, direct-deposit refunds within 21 days. Paper returns take 6 weeks or more, and refunds claiming EITC or ACTC are held until at least mid-February.
What if my W-2 never arrives?
Contact your employer first. If it is still missing at the end of February, call the IRS at 800-829-1040. You can file using Form 4852 and amend later if the real W-2 differs.
Do I need a bank account for my refund?
In practice, yes. The IRS began phasing out paper refund checks on September 30, 2025 and relies on direct deposit for most taxpayers.
