Filing a federal tax return doesn’t have to cost anything for the large majority of taxpayers, yet the program that makes that true remains one of the IRS’s most underused offerings. IRS Free File currently allows anyone with an adjusted gross income of $89,000 or less to prepare and e-file a federal return at no cost through guided software from IRS partner companies — a threshold that, according to Free File Alliance figures reported independently, now covers more than 70 percent of all taxpayers, even though fewer than 3 percent actually use the program in a given year.
How the two Free File tracks actually differ
The IRS splits Free File into two distinct paths rather than one blanket offering. Taxpayers at or under the $89,000 AGI threshold can use guided software from a Free File Alliance partner company, which walks the filer through simple questions, performs the math automatically, and in many cases includes free state tax preparation as well, depending on which partner is chosen. Above that threshold, the program still offers Free File Fillable Forms to any taxpayer regardless of income — but that option requires the filer to enter data into electronic versions of the actual IRS forms themselves, with limited built-in calculation help and no state filing included.
The distinction is deliberate: guided software is meant to function like commercial tax software minus the price tag, while Fillable Forms exist as a no-cost option for filers comfortable working directly from IRS instructions. The IRS is explicit that eligible taxpayers must start at IRS.gov itself to access either option — going directly to a partner company’s commercial website instead bypasses the free version entirely, even for the same company that appears in the IRS’s own partner list.
The consumer protections built into the guided track

Free File’s guided software track carries restrictions the IRS imposes on its partner companies specifically to prevent the “free” label from becoming a bait for paid upsells. The IRS states directly that no upselling of additional services or hidden fees is permitted, including refund-anticipation loans, audit-protection add-ons, or other paid bank products commonly bundled into commercial tax software. Partner companies are also barred from deceptive online practices, such as confusing site designs meant to steer a filer toward a paid product after they’ve already begun.
A separate guarantee covers the software’s own errors: if a Free File Alliance member’s calculation error causes an IRS penalty or interest charge, that company is obligated to cover the resulting cost. That protection only applies to the guided software track, since Fillable Forms involve minimal built-in calculation and place more of the arithmetic responsibility directly on the filer.
State residency and age carve out one further exception worth knowing about: taxpayers in a specific list of states can access free Spanish-language filing through a designated Free File partner if they’re between 17 and 85 with $89,000 or less in AGI, or if they’re active-duty military regardless of income. Active-duty service members get a broader accommodation across the program generally — a guaranteed free federal return through any guided-tax partner as long as their AGI falls within that partner’s threshold, independent of the state-specific Spanish-language option.
Why eligibility hasn’t translated into use
The gap between who qualifies and who actually files through the program is the detail that stands out most in the IRS’s own numbers. Free File Alliance leadership has pointed to a persistent misconception that the program only handles the simplest returns, when in practice small-business owners, gig workers, and landlords with multiple rental properties can all use it as long as their AGI clears the threshold — the limitation is income level, not the complexity of the return itself.
Free File’s scope has narrowed in one specific way this year: the IRS’s separate, no-partner “Direct File” pilot program, which had let some taxpayers file directly with the agency without going through a private company at all, has been discontinued. That leaves Free File’s guided-software and Fillable Forms tracks as the primary no-cost federal filing options remaining, both still run through Free File Alliance partner companies rather than a government-built platform.
Free File also has real limits worth knowing before relying on it. The program only accepts the current tax year’s return — a taxpayer with an unfiled prior-year return has to pursue that separately through the IRS’s past-due filing process, since Free File cannot process back taxes. Amended returns are similarly split by track: a filer can amend a return using the same guided software they used originally, but Fillable Forms currently has no capability to prepare or file an amendment at all, meaning a Fillable Forms user who needs to correct a return has to find a different route entirely.
A filer who needs more time doesn’t lose access to the free option by requesting it. Both tracks can file Form 4868 through Free File itself, which pushes the filing deadline to October 15 — but the extension only buys time to file the paperwork, not to pay. Any balance due is still owed by the standard April 15 deadline regardless of whether an extension was filed, and missing that payment deadline can trigger penalties even on a return that’s otherwise filed on time under the extended date.
