To file your U.S. federal taxes, you gather your income documents, choose how you want to file (software, professional, or by hand), and submit Form 1040 and any needed schedules to the IRS by the April deadline, paying any tax due. For most people in 2026, this means filing a 2025 return by April 15, 2026, or requesting an extension if needed.

Quick Scoop

1. Key 2026 timing and basics

  • The IRS 2026 filing season (for your 2025 income) opens in late January; for 2026 it opens January 26, 2026.
  • The standard federal deadline to file 2025 returns is April 15, 2026, with an optional six‑month extension to October 15, 2026 (but you still must pay any tax you owe by April 15).
  • You must usually file if your gross income is at least your standard deduction for the year, plus in some cases even if you are below that (for example, if you owe certain special taxes or had marketplace insurance credits).

Think of filing like closing the “book” on your financial year: you total income, subtract deductions and credits, and see whether you still owe or get money back.

2. Step‑by‑step: how to file taxes

Here’s a simple roadmap for a typical individual filing a U.S. federal return:

  1. Collect your documents
    • Income forms: W‑2s from employers, 1099s from gig work, bank interest, brokerage accounts, retirement distributions, etc.
 * Other items: records of deductible expenses (student loan interest, education costs, some medical costs, charitable donations, etc.), and prior‑year return if available.
  1. Decide how you’ll file
    • Online tax software (e.g., popular commercial tools) that guide you through questions and e‑file for you.
 * Free options, if you qualify: IRS Free File partner programs and IRS Free Fillable Forms let many taxpayers file at no cost, especially if income is under a certain threshold (around the high‑$80k range for many programs in 2026).

 * Tax professional: an enrolled agent or CPA can prepare and e‑file your return for a fee, which is often worth it if you own a business, have complex investments, or major life changes.
  1. Choose your filing status and dependents
    • Common statuses: Single, Married Filing Jointly, Married Filing Separately, Head of Household, Qualifying Surviving Spouse.
 * Your status affects your standard deduction and eligibility for credits, so answer software questions carefully or follow the IRS instructions if filing by hand.
  1. Report your income
    • Enter all wages, salaries, and tips from W‑2s, plus interest, dividends, freelance and gig income, and other income on Form 1040 and its schedules.
 * Newer rules mean more people receive 1099‑K forms for payments from apps and marketplaces, and 1099‑DA for digital asset (crypto) transactions; all taxable income must still be reported even if you do not receive these forms.
  1. Claim deductions and credits
    • Decide whether to take the standard deduction or itemize (mortgage interest, state taxes, charitable giving, certain medical costs, and more).
 * Credits directly reduce tax owed (e.g., Earned Income Tax Credit, Child Tax Credit, education credits) and are handled automatically by most software if you answer questions accurately.

 * New 2026‑season items, like a Schedule 1‑A for certain newly enacted deductions (such as special treatment of tips, overtime, car loan interest, and enhanced deductions for seniors), must be completed if they apply to you.
  1. Review, then file (e‑file or mail)
    • E‑file is fastest, generally more secure, and leads to quicker refunds, especially when you choose direct deposit.
 * If you prefer paper, you can print the current‑year forms from IRS.gov or pick up copies at many libraries, fill them out, and mail them, understanding that refunds by paper check are slower.
  1. Pay or track your refund
    • If you owe, you can usually pay online by bank transfer, debit, credit, or scheduled payments.
 * If you’re due a refund, the IRS strongly encourages direct deposit into a bank account, and is moving away from paper refund checks.

 * You can check refund status using IRS online tools once your return is processed.

3. Real‑world tips and forum‑style insights

People asking “how do I file taxes?” on forums often feel anxious and worry they’ll “do it wrong,” especially when using software for the first time. A few practical angles from that kind of discussion:

  • Many first‑timers use guided software (like the big‑name tools) because it turns the tax return into an interview: answer plain‑language questions, and it fills out Form 1040 and schedules in the background.
  • Community advice often emphasizes that you can explore software or paper forms without risk as long as the return you finally submit is honest and complete; you can practice with hypothetical numbers and then overwrite with real data before filing.
  • Moderated finance communities repeatedly warn against sharing personal details (Social Security number, birth date, full name) with strangers who offer to “do your taxes for quick money,” as that’s a classic identity‑theft setup.

If you are young or filing for the first time, many people also recommend free in‑person help programs (like community tax‑aid and volunteer preparer sites), which can walk you through your return and answer basic questions.

4. Ways to file for free in 2026

Several options let many people pay nothing to prepare and submit a federal return:

  • IRS Free File : For eligible taxpayers (up to a middle‑income threshold), this pairs you with partner companies that offer guided online filing at no cost.
  • IRS Free Fillable Forms : Online versions of the forms where you type directly into Form 1040; some math is automated, but there is little guidance, so it suits people comfortable reading instructions.
  • Third‑party free offerings : Some apps and companies (including money‑transfer apps) provide completely free filing tools within their platforms for most simple returns.
  • Military and veteran programs : Services like MilTax offer free preparation and e‑filing for eligible service members and some veterans.

All of these choices still send the same core information to the IRS—your income, deductions, credits, and final tax owed or refund due.

5. If your situation is more complex

You may want extra help (or a paid preparer) if:

  • You run a business, are self‑employed, or have many gig‑economy income streams.
  • You trade frequently in stocks, options, digital assets, or own rental properties.
  • You had big life events (marriage, divorce, buying or selling a home, significant medical bills).
  • You need to amend a prior‑year return with Form 1040‑X.

Professionals are used to late filers, messy records, and complicated situations and can suggest ways to organize documents and plan better for next year.

TL;DR:
In 2026, you file your 2025 federal return by collecting your income forms, picking a filing method (software, free tools, or professional), filling out Form 1040 with all income, deductions, and credits, and submitting it—ideally by e‑file with direct deposit—by April 15, or with an extension if necessary.
