IRS Free File is a partnership between the IRS and trusted tax software providers that lets eligible taxpayers prepare and file their federal returns online for free.

The program supports many common — and even moderately complex — tax situations, as long as your adjusted gross income (AGI) falls below the annual limit. For most filers, it’s a straightforward way to submit a return, claim credits and avoid paying for commercial tax software, all through an IRS-backed platform.

What Is IRS Free File?

IRS Free File is a government program that lets eligible taxpayers file their federal taxes online for free using trusted partner software.

It offers two options based on your income and how much guidance you want.

• Option 1: Guided tax software (AGI $89,000 or less). If your adjusted gross income (AGI) is $89,000 or less, you can use free guided software from participating providers. The program walks you through your return step by step and automatically handles the math. Federal filing is free for everyone who qualifies, but free state filing depends on the provider and your state.
• Option 2: Free Fillable Forms (any income level). If you earn more than $89,000 — or prefer to file on your own — you can use Free Fillable Forms. This option gives you electronic versions of IRS forms to complete yourself. It’s still free, but it doesn’t include guidance, built-in calculations, or free state returns.

How IRS Free File Works

The IRS doesn’t provide its own tax software. Instead, it partners with eight companies — including TaxAct, TaxSlayer, and FreeTaxUSA — that offer their software for free through the IRS Free File program.

There are two ways to file.

Guided Tax Software

If your adjusted gross income (AGI) is $89,000 or less, you can use guided software at no cost.

You choose a provider through the IRS website, answer simple questions about your income and deductions, and the software does the calculations for you. It also checks for common errors and helps you claim eligible credits.

Federal filing is free. State filing may also be free, depending on the provider and where you live.

Free Fillable Forms

If your income is above $89,000, you can use Free Fillable Forms.

This option gives you electronic versions of IRS forms to complete yourself. There’s no guidance or automatic math — you enter everything manually.

It’s still free, but best for people who are comfortable preparing their own returns.

How to File for Free

Most filers qualify for guided, free software. Higher earners can still file for free — they just have to do more of the work themselves.

Who Is Eligible for IRS Free File?

For tax year 2025 (filed in 2026), IRS Free File is available to taxpayers with an adjusted gross income (AGI) of $89,000 or less.

AGI — not gross income — is the number that determines eligibility. Your gross income includes all the money you earned during the year. Certain “above-the-line” deductions are then subtracted to arrive at your AGI. This figure matters because it affects not only Free File eligibility, but also whether you qualify for key tax credits and deductions.

Common Adjustments That Lower AGI

Above-the-line deductions that can reduce your AGI include:

• Retirement account contributions
• Student loan interest
• Educator expenses
• Health savings account (HSA) contributions
• Alimony from qualifying older divorce agreements
• Select self-employment or business deductions

Who Should Use IRS Free File?

IRS Free File works best for many — but not all — taxpayers.

Good candidates include:

• W-2 employees
• Filers with straightforward tax situations
• First-time filers
• Refund-focused filers who want guided help without paying for software

When IRS Free File May Not Be the Best Fit

Some filers may find paid tax software or professional help more efficient, especially those with:

• Self-employment or gig income
• Itemized deductions
• Multi-state or international income
• Complex credits or business activity

That said, the IRS notes that many taxpayers with more complicated returns can still use Free File successfully, particularly if they’re comfortable entering detailed information and reviewing their return carefully.

IRS Free File Checklist: What to Gather Before You Start

Taking five minutes to gather your documents upfront can make the filing process much smoother — and help you avoid delays or rejected returns.

Before you begin, have the following ready:

• Last year’s tax return (helpful for reference and identity verification)
• Social Security numbers for yourself, your spouse and dependents
• All income forms, such as W-2s, 1099s and other earnings statements
• Health coverage forms (ACA-related documents, if applicable)
• Identity verification information, such as prior-year AGI or IP PIN (if issued)
• Bank routing and account numbers if you want your refund deposited directly

Having these documents in front of you reduces guesswork and lowers the risk of mistakes.

IRS Free File Mistakes to Avoid

IRS Free File is straightforward, but a few common missteps can cost you time — or even money.

Here’s what to watch for:

• Starting on a provider’s website instead of IRS.gov. Always begin at IRS.gov to ensure you access the official Free File version.
• Not checking whether your state return is free. Federal filing is free, but state filing may vary by provider and location.
• Accidentally upgrading to a paid version. Some providers offer add-ons or premium tiers. Make sure you stay within the Free File option.
• Rushing through entries and missing credits. Double-check income amounts, dependents and eligibility questions to avoid leaving money on the table.
• Waiting until the last minute to file. Filing close to the deadline increases stress and the chance of errors — especially if identity verification issues arise.

What Happens After You File With IRS Free File?

Once you submit your return electronically, the IRS begins processing it.

Most e-filed returns are processed — and refunds issued — within 21 days. If you chose direct deposit, your refund typically arrives faster than a paper check.

You can track your refund using the IRS Where’s My Refund? tool as soon as 24 hours after filing. The system updates daily. To check your status, you’ll need:

• Your Social Security number
• Your filing status
• The exact refund amount listed on your return

Why Refunds Get Delayed

Even with electronic filing, some returns take longer. Common reasons include returns that:

• Contain errors or missing information
• Don’t match IRS records
• Trigger identity theft or fraud safeguards
• Include certain tax credits that require additional review
• Claim an injured spouse allocation

If your return is rejected, you can usually fix the issue and resubmit it. If you need to correct a return that has already been accepted, you’ll file Form 1040-X (Amended U.S. Individual Income Tax Return).

IRS Free File Deadlines and Key Dates

IRS Free File typically opens in early January each year. For the 2026 tax season, guided Free File software became available Jan. 9, and Free Fillable Forms opened Jan. 26. (Start dates can vary slightly from year to year.)

Regardless of how you file, Tax Day is April 15.

If you owe taxes:

• Payment is due by April 15
• You can request a filing extension, but that does not extend your payment deadline

An extension gives you more time to file your paperwork — usually until mid-October — but any taxes owed must still be paid (or a payment plan arranged) by Tax Day to avoid penalties and interest.

Bottom Line: Is IRS Free File Right for You?

IRS Free File is available to most taxpayers, and provides a fast, free and secure way to file taxes through trusted third-party providers. Those who earn more than the $89,000 income limit must determine whether they’re able and willing to navigate Free Fillable Forms, but those under the threshold — even those with fairly complex returns — stand to benefit from Free File. 

However, those with especially complicated tax situations, some business owners, multi-state or foreign-income earners and those whose states aren’t supported might do better with professional help or paid software.
