Filing taxes for the first time can feel overwhelming. But for most people with a simple tax situation, the process is straightforward — and many first-time filers end up getting money back.
This step-by-step guide walks you through exactly what to do to file your federal taxes in 2026, including which forms to use, what documents you need, and how to avoid common mistakes.
Rates and figures as of May 2026.
Do You Have to File?
Not everyone is required to file a federal tax return. The IRS sets income thresholds that determine whether you must file. For the 2025 tax year (filed in 2026):
| Filing Status | Must File If Gross Income Exceeds |
|---|---|
| Single (under 65) | $14,600 |
| Single (65 or older) | $16,550 |
| Married Filing Jointly (both under 65) | $29,200 |
| Married Filing Jointly (one spouse 65+) | $30,750 |
| Head of Household (under 65) | $21,900 |
Even if you fall below the threshold, you should still file if taxes were withheld from your paycheck. You may receive a refund.
Step 1: Gather Your Documents
Before you start, collect all the documents you will need:
Income Documents
- W-2: From your employer — shows your wages and the taxes withheld
- 1099-NEC: If you did freelance or contract work and earned $600 or more from any client
- 1099-INT: From your bank for interest earned on savings accounts
- 1099-DIV: From brokerage accounts for dividends received
- 1099-B: From your brokerage for investment sales
- SSA-1099: If you received Social Security benefits
Deduction Documents (if itemizing)
- Mortgage interest statement (Form 1098)
- Property tax receipts
- Charitable donation receipts
- Student loan interest statement (Form 1098-E)
Other Items
- Your Social Security number and those of any dependents
- Last year’s tax return (if you filed before) — useful for reference
- Bank account and routing numbers for direct deposit of any refund
Step 2: Choose Your Filing Status
Your filing status affects your standard deduction and tax brackets. The five options are:
- Single: Unmarried and not qualifying for another status
- Married Filing Jointly: Married and filing one return together
- Married Filing Separately: Married but filing separate returns
- Head of Household: Unmarried and paid more than half the cost of a home for a qualifying person
- Qualifying Surviving Spouse: Widowed in the past 2 years with a dependent child
Most first-time filers are single. If you are unmarried and supporting a dependent, head of household often results in a lower tax bill.
Step 3: Decide — Standard Deduction or Itemize?
You can reduce your taxable income in one of two ways:
Standard Deduction (Most Filers)
A flat amount you subtract from your income without tracking individual deductions. For 2025 returns:
- Single: $14,600
- Married Filing Jointly: $29,200
- Head of Household: $21,900
About 90% of filers take the standard deduction because it is larger than their itemized deductions would be.
Itemized Deductions
You list specific deductible expenses — mortgage interest, state and local taxes, charitable donations, medical expenses — and deduct the total. Only worthwhile if your itemized total exceeds the standard deduction.
Step 4: Choose How to File
IRS Free File (Income Under $79,000)
The IRS partners with tax software companies to offer free filing for taxpayers with adjusted gross income under $79,000. Go to IRS.gov to access Free File options.
Tax Software
- TurboTax Free Edition: Best for the simplest returns (W-2 income, no investments)
- H&R Block Free Online: Similar to TurboTax, solid free option
- FreeTaxUSA: $0 federal, $14.99 state — great value for most returns
- Cash App Taxes: Completely free for federal and state
CPA or Tax Professional
Worth it if you have a complex situation: self-employment income, investments, rental property, or major life changes. Expect to pay $150–$400+ for a professional return.
Step 5: Fill Out and Submit Your Return
Most first-time filers need only Form 1040 — the main federal income tax form. Tax software guides you through this with step-by-step questions.
You will enter:
- Your personal information and filing status
- Income from all sources (W-2, 1099s, etc.)
- Above-the-line deductions (student loan interest, IRA contributions, etc.)
- Standard or itemized deductions
- Tax credits you qualify for (child tax credit, earned income credit, etc.)
- Taxes already paid (withheld from paychecks)
The software calculates your refund or amount owed. Review everything, then e-file directly from the software.
Step 6: Pay Any Tax Owed
If you owe taxes, you can pay by bank account (direct debit), credit card, debit card, or check. You can also set up a payment plan with the IRS if you cannot pay the full amount at once.
If you expect to owe taxes regularly (as a self-employed person, for example), you may need to make quarterly estimated tax payments to avoid underpayment penalties.
Common First-Timer Mistakes to Avoid
- Missing the deadline: April 15 is the filing deadline. File for an extension if you need more time — but pay any taxes owed by April 15 regardless.
- Wrong Social Security number: Double-check all SSNs. An error here can delay your refund significantly.
- Missing income: You must report all income, including freelance work, investment income, and side gig income, even if you did not receive a 1099.
- Not saving your return: Keep a copy of your tax return for at least 3 years. You will need last year’s return to file next year.
- Choosing the wrong filing status: Head of household has a bigger deduction than single — make sure you choose correctly if you qualify.
Key Takeaways
- Gather W-2s, 1099s, and Social Security numbers before you start
- Most first-time filers take the standard deduction — $14,600 for single filers in 2026
- File for free if your income is under $79,000 through the IRS Free File program
- E-file and choose direct deposit for the fastest refund (typically 21 days)
- The deadline is April 15, 2026 — file an extension if you are not ready, but pay any taxes owed by April 15
