Whether you landed your first job, started freelancing, or are simply filing independently for the first time this year, find out everything you need to know in this first time tax filer guide.
Not everyone is required to file a federal tax return, but most working adults are. As a general rule, if you earned income in 2025, you likely need to file. For the 2025 tax year (filed in 2026), the IRS requires most single filers under 65 to file if their gross income was $14,600 or more.
Even if your income falls below that threshold, filing may still be worth doing. If taxes were withheld from your paychecks throughout the year, filing is the only way to get that money back as a refund. Many first-time filers are pleasantly surprised to find they are owed money, not the other way around.
Getting organized before you start is the single most effective way to make the filing process smoother. Here is what to have on hand.
W-2: If you worked as an employee, your employer is required to send you a W-2 by January 31. This form shows your total wages and the taxes withheld from your paychecks throughout the year. It is the most important document most first-time filers need.
1099 forms: If you did any freelance, contract, or gig work, you may receive one or more 1099 forms instead of a W-2. A 1099-NEC reports nonemployee compensation; a 1099-K may arrive if you received payments through platforms like Venmo, PayPal, or a marketplace. If you earned interest from a bank account, you may also receive a 1099-INT.
Social Security Number: You will need your SSN (and those of any dependents, if applicable) to complete your return.
Bank account information: If you are expecting a refund, direct deposit is the fastest way to receive it. Have your routing and account numbers ready.
Records of deductible expenses: If you think you may itemize deductions (more on that below), gather records of things like mortgage interest, charitable donations, medical expenses, or student loan interest paid during the year.
Missing a tax deadline can result in penalties and interest, so mark these dates now.
The federal tax filing deadline for the 2025 tax year is April 15, 2026. If you need more time, you can file for an automatic six-month extension, which pushes your filing deadline to October 15, 2026. Important note: an extension to file is not an extension to pay. If you owe taxes, payment is still due by April 15 to avoid penalties and interest.
Most states with an income tax follow a similar deadline, but confirm your state’s specific due date.
Two decisions will shape your return more than almost anything else: your filing status and whether to take the standard deduction or itemize.
Filing status determines your tax bracket and the deductions available to you. Most first-time filers will file as Single. If you have a child or a qualifying dependent and you paid more than half the cost of keeping up a home, Head of Household may apply and comes with more favorable rates.
Standard vs. itemized deductions: A deduction reduces the amount of your income that is subject to tax. The standard deduction for single filers in 2026 (for the 2025 tax year) is $15,000. This means if you take the standard deduction, $15,000 is automatically subtracted from your taxable income without needing to document individual expenses.
Itemizing makes sense only if your qualifying deductible expenses (mortgage interest, state and local taxes up to $10,000, charitable contributions, certain medical expenses, etc.) add up to more than $15,000. For most first-time filers, the standard deduction is the right and simpler choice.
Learn the most common tax planning mistakes, how they increase tax liability, and how proactive tax planning helps taxpayers avoid costly surprises.
Knowing what to avoid is half the battle.
Missing income. All income is reportable, including freelance work, side gigs, and interest earned on savings accounts, even if you did not receive a formal tax form for it. Leaving income off your return is one of the most common triggers for IRS notices.
Entering incorrect personal information. A typo in your Social Security Number, name, or bank account details can delay your refund significantly. Double-check everything before you submit.
Missing the deadline without filing an extension. If you know you are not going to be ready by April 15, file for an extension. The penalty for failing to file is steeper than the penalty for failing to pay.
Overlooking deductions and credits you qualify for. First-time filers commonly miss the student loan interest deduction, the Earned Income Tax Credit (if income-eligible), or the Saver’s Credit for retirement contributions. These can meaningfully reduce your tax bill or increase your refund.
Filing before all your documents arrive. W-2s and 1099s have a legal delivery deadline of January 31, but some forms (like certain investment statements) can arrive later. Filing too early with incomplete information may require an amended return.
This is the question most first-time filers spend the most time on, and the honest answer is: it depends on your situation.
If your income comes entirely from one W-2, you have no investments or freelance income, and you are taking the standard deduction, tax software can handle your return reasonably well. The process is fairly straightforward.
But if any of the following apply, working with a CPA is worth the investment:
You have multiple income sources, including freelance or 1099 income. You are self-employed or started a small business. You have significant student loan debt and are evaluating income-driven repayment options. You experienced a major life change in the past year, such as getting married, having a child, or receiving an inheritance. You are simply not confident in what you are doing and do not want to risk errors on an official federal filing.
A CPA doesn’t just file your return. They identify deductions and credits you might miss, help you avoid costly mistakes, and give you a clear picture of your tax situation going forward. For many first-time filers, the peace of mind alone is worth it.
