Taxpayers who asked for more time to file their 2025 return still have a hard deadline ahead of them, and the IRS is using its late-August reminder to push people toward filing now instead of waiting until the last week. Free, guided software remains open for a large share of extension filers, but the income cutoff that determines who can use it, and what happens above that line, is worth checking before assuming the free option applies.
The $89,000 Line That Decides Who Gets Guided Software
The IRS confirmed on Aug. 26, 2026, that IRS Free File remains available through Oct. 15, 2026, and that its guided tax preparation option is open to taxpayers with a 2025 adjusted gross income of $89,000 or less. Guided preparation means a trusted IRS partner’s software walks a filer through their return step by step, with built-in error checks, the same experience many paid programs charge for, at no cost to anyone under the threshold.
Married couples filing jointly, single filers, and heads of household are all measured against the same $89,000 figure; it’s a household income test tied to the return being filed, not a per-person limit. A couple with combined 2025 adjusted gross income of $95,000 falls above the line even if each spouse individually earned less than $89,000, so a household near the cutoff should calculate the actual combined figure rather than assume each spouse’s separate income is what counts.

What Filers Above the Threshold Get Instead
Taxpayers whose 2025 adjusted gross income exceeds $89,000 aren’t shut out of free filing entirely, but they lose the guided, step-by-step software. Instead, they can use Free File Fillable Forms, an electronic version of IRS paper forms that still allows free e-filing but assumes the filer already knows how to fill out a tax return without software prompts or built-in guidance. It’s a meaningfully different product: no interview-style questions, no automatic calculations beyond basic math, and no state-return option, which several of the guided partner programs include for eligible filers.
That gap matters most for households with more complicated returns, self-employment income, itemized deductions, or multiple income sources, since Fillable Forms offers none of the prompts that catch a missed schedule or a miscalculated credit. A higher-income extension filer who wants that kind of help typically has to pay for tax software or a preparer, even though the e-filing itself remains free either way.
Why the IRS Wants Extension Filers Moving Now, Not in October
An extension to file is not an extension to pay. The IRS reminder is explicit that anyone who owes tax should pay as much as they can as soon as possible, since penalties and interest keep accruing on unpaid balances regardless of when the return itself is actually filed. Filing before the Oct. 15 deadline, rather than on it, also gives a taxpayer more room to fix errors, gather missing documents, or set up a payment plan if they discover they owe more than expected, instead of scrambling in the final days before the deadline closes.
Filing over the summer rather than in the fall also means avoiding the seasonal crunch that hits both IRS phone lines and paid preparers in the two weeks before an October deadline. A taxpayer who runs into a question about a missing form or an unclear credit has more time to get it answered correctly in August or September than in the first week of October, when preparer availability and IRS response times both tend to slow under the volume of last-minute filers.
Refunds Move Faster Through E-File and Direct Deposit
For extension filers who are actually due money back, the IRS’s own guidance points to e-filing combined with direct deposit as the fastest way to get a refund, regardless of which Free File option a taxpayer uses. That combination avoids the added mail time of a paper check and the manual processing steps that come with a paper return, both of which can push a refund out by weeks compared with an electronically filed one.
What an Extension Filer Should Check Before Oct. 15
Anyone who requested a 2025 extension and hasn’t filed yet has a narrowing window, and Oct. 15 is the final date; there is no further extension available beyond it for a typical filer. The first practical step is confirming which side of the $89,000 adjusted gross income line their household falls on, since that determines whether guided software or fillable forms is the free option available to them. From there, gathering the same documents any filer needs, W-2s, 1099s, and records of any deductions or credits being claimed, and starting the return now rather than in the first two weeks of October reduces the odds of running into the deadline with an incomplete or rushed filing. Taxpayers can start the process directly through IRS Free File: Do Your Taxes for Free on IRS.gov, where the system routes filers to either the guided software or the fillable-forms option based on the income figure they enter.
