If you are about to file taxes for the first time, it can feel intimidating. The good news: for most young people with a job, a student loan or a side hustle, filing is simpler than it looks. This guide focuses on the US federal return for the 2026 tax year, which is filed in early 2027. We cover the UK, Canada and Nigeria briefly at the end.
Do you need to file?
You generally need to file if your income is above the standard deduction for your filing status, or if you had self-employment income of $400 or more. Even if you do not have to, filing can be worth it: if tax was withheld from your paychecks, you may get a refund.
Documents to gather
- Form W-2 from each employer.
- Form 1099-NEC or 1099-K if you did freelance or gig work.
- Form 1099-INT for interest from savings accounts.
- Form 1098-T for tuition and 1098-E for student loan interest.
- Form 1099-DA if you sold crypto through a broker.
- Your Social Security number and bank details for a direct-deposit refund.
Step by step
- Choose your filing status: most young single filers use “Single”. If your parents can claim you as a dependent, you must say so.
- Report all income from every W-2 and 1099.
- Take the standard deduction unless your itemized deductions are larger, which is rare for first-time filers.
- Claim credits you qualify for, such as education credits or the Earned Income Tax Credit.
- Check and submit electronically, and choose direct deposit for any refund.
Free ways to file
If your income is below the IRS Free File limit, you can use free guided software through the IRS website. Volunteer Income Tax Assistance (VITA) sites also help eligible people file for free. Many commercial services offer free versions for simple returns, but watch for upsells.
Side hustle income
If you earned money from freelancing or gig work, you report it on Schedule C and may owe self-employment tax. Estimate what you owe with our Freelance Tax Estimator and set money aside through the year.
Outside the US
- UK: most employees pay tax through PAYE automatically; you only file a Self Assessment return if you have untaxed income, such as self-employment above £1,000.
- Canada: file a return each year with the CRA, even with low income, to access benefits and build RRSP room.
- Nigeria: employees are taxed through PAYE; self-employed people must file with the relevant tax authority under the new tax laws.
Common first-time filing mistakes
- Missing income: forgetting a second job, side hustle or interest from a savings account.
- Wrong filing status: check whether your parents can still claim you as a dependent.
- Typos: a wrong Social Security number or bank account number can delay your refund.
- Missing credits: students may qualify for education credits, and lower earners may qualify for the Earned Income Tax Credit.
- Not keeping copies: save your return and documents for at least three years.
What to do after you file
Track your refund on the tax authority’s website. If you owe money, pay by the deadline or set up a payment plan to avoid extra penalties. Then look ahead: if you had a big refund, you may be over-withholding, and if you owed a lot, adjust your withholding or set money aside monthly. Freelancers and side hustlers can estimate what to save with our Freelance Tax Estimator.
Your first-time tax filing checklist
Tick these off before you submit your return.
- All income forms collected (W-2, 1099, P60 or T4, depending on your country).
- Personal details and bank information double-checked.
- Filing status and dependency confirmed.
- Deductions and credits reviewed, including education credits.
- Return saved as a PDF along with all supporting documents.
- Refund or payment date added to your calendar.
Filing early gives you time to fix mistakes and get any refund sooner. Next year will be much easier once you have done it once.

Frequently asked questions
When is the US tax deadline?
Federal returns for the 2026 tax year are usually due in mid-April 2027. You can request an extension to file, but not to pay what you owe.
What if I make a mistake?
You can file an amended return using Form 1040-X. Most small mistakes are easy to fix.
Can my parents still claim me?
If you are a student under 24 or otherwise qualify as their dependent, they may be able to claim you. Coordinate so you do not both claim the same person.
Can I file my taxes for free?
Often yes. Many people with simple returns can file free through official programs or free tax software. Check the IRS, HMRC, CRA or FIRS websites for options.
