If you earned income this year and you're filing a federal tax return for the first time, the process is more manageable than it looks. The IRS receives roughly 160 million individual returns each year, and most first-time filers can complete theirs in an afternoon using free or low-cost software. This guide walks you through the mechanics of filing: what counts as income, which forms you need, how to choose a filing method, and how to avoid the penalties that catch beginners off guard.
Step 1: Confirm Whether You Must File
You generally must file a federal return if your gross income reaches the standard deduction for your filing status. For tax year 2024, that threshold is $14,600 for single filers, $29,200 for married couples filing jointly, and $21,900 for heads of household. If you are self-employed and earned $400 or more in net self-employment income, you must file regardless of the threshold, because self-employment tax applies.
Even when filing is optional, it often pays to file anyway. You must file to claim a refund of taxes withheld from your paycheck, to receive refundable credits such as the Earned Income Tax Credit, or to claim the American Opportunity Tax Credit for education expenses. If your only income was Social Security benefits or a small amount of interest, you may not need to file at all.
Step 2: Gather Your Income and Identity Documents
Before you open any software, collect the paperwork that reports your income. Employers and payers send these forms by the end of January, and the IRS receives copies, so mismatches are easy for the agency to detect.
- Form W-2 — wages from an employer, including federal and state withholding.
- Form 1099-NEC — payments of $600 or more for freelance, contract, or gig work.
- Form 1099-INT or 1099-DIV — interest and dividend income from banks and brokerages.
- Form 1099-G — unemployment compensation and certain state refunds.
- Form SSA-1099 — Social Security benefits.
- Form 1098-T — tuition paid to a college or university.
- Form 1098 — mortgage interest, if you own a home.
You will also need your Social Security number or Individual Taxpayer Identification Number, a photo ID, last year's return if you have one, and your bank account and routing numbers for direct deposit. Direct deposit is the fastest way to receive a refund; the IRS issues most electronic refunds within 21 days.
Step 3: Choose How You Will File
There are three main paths, and the right one depends on the complexity of your return.
IRS Free File and Free File Fillable Forms
If your adjusted gross income was $84,000 or less in 2024, you can use IRS Free File, a partnership between the IRS and commercial tax software companies that offers guided preparation at no cost. Above that income level, Free File Fillable Forms let you complete the forms yourself electronically at no charge, though the software performs only basic math and does not interview you.
Commercial Tax Software
Paid products from major providers handle itemized deductions, investment income, rental property, and multi-state returns. Expect to pay roughly $40 to $120 depending on the package and whether you need state filing. The software asks questions in plain language and fills in the forms for you, which reduces arithmetic and transcription errors.
Tax Professionals
A CPA or enrolled agent is worth the cost if you are self-employed, sold a home or investments, exercised stock options, or had a major life change such as marriage, divorce, or a new dependent. Enrolled agents and CPAs can represent you before the IRS if questions arise later.
Step 4: Report Income and Claim Deductions and Credits
Enter each income form exactly as issued. If you worked as an independent contractor, you report that income on Schedule C and deduct ordinary and necessary business expenses such as supplies, mileage, and a home office used exclusively for work. You will also owe self-employment tax of 15.3% on net earnings, which covers Social Security and Medicare.
Most beginners take the standard deduction rather than itemizing. For 2024, the standard deduction is $14,600 single, $29,200 married filing jointly, and $21,900 head of household. Itemizing makes sense mainly when deductible expenses exceed those amounts — commonly mortgage interest, state and local taxes up to the $10,000 cap, charitable contributions, and large medical expenses.
Credits reduce your tax bill dollar for dollar, which makes them more valuable than deductions. Common ones for beginners include the Earned Income Tax Credit, the Child Tax Credit worth up to $2,000 per qualifying child, the Child and Dependent Care Credit, and education credits. Always check eligibility before assuming you do not qualify.
Step 5: File, Pay, and Keep Records
The federal filing deadline is April 15 for most taxpayers. If you owe money and cannot pay in full, file on time anyway and request an installment agreement through the IRS Online Payment Agreement tool; the failure-to-file penalty is far steeper than the failure-to-pay penalty. If you need more time, Form 4868 grants an automatic six-month extension to October 15, but it extends the filing date only, not the payment deadline.
After filing, keep a copy of your return and supporting documents for at least three years from the filing date, which is the IRS's standard audit window. If you discover an error after submitting, file Form 1040-X to amend. Finally, check your withholding each year using the IRS Tax Withholding Estimator so you are not surprised by a balance due next April.
What to Remember
- File if your income meets the threshold for your filing status, or if you are self-employed with $400 or more in net earnings.
- Collect every W-2, 1099, and 1098 before you start; the IRS already has copies.
- Use IRS Free File if your income qualifies, and choose a professional for complex situations.
- Take the standard deduction unless your itemized expenses clearly exceed it, and always check credits.
- Meet the April 15 deadline even if you cannot pay, and keep records for three years.
