Which tax software products allow e-filing Form 1040-X for 2025 tax returns?

1. Which consumer tax apps say they let filers e‑file a 1040‑X for 2025 — and what the fine print is

FreeTaxUSA explicitly advertises preparation and e‑filing of Form 1040‑X for recent years and notes an amended‑return fee (example: $16.98 for amended filing in their materials) ^{[5] [11]}, while TurboTax documents that users can generally e‑file amended federal returns for 2025 (and 2024, 2023) provided the original return was e‑filed through TurboTax; TurboTax warns some unique situations still require printing and mailing ^{[4] [12]}. Express1040 and TaxHawk both advertise free federal filing and claim the ability to file 1040‑X for 2025 tax preparation, positioning themselves as options for amended e‑filing ^{[6] [7]}. eFile.com similarly confirms that filers who originally e‑filed on its platform can prepare and e‑file a 2025 amendment within the same account — but warns its amendment e‑file capability may be limited to returns originally filed on eFile.com ^[8].

2. Professional and preparer software that supports e‑filing 1040‑X

TaxSlayer Pro’s support documentation states both its desktop and ProWeb products support e‑filing Form 1040‑X, and it lays out operational details and limitations (for example, original‑return method considerations) for preparers ^[9]. Drake Tax’s knowledge base confirms its software generates and e‑files 1040‑X for eligible years and cautions that only 2023–2025 forms are eligible for electronic filing at this time ^[10]. These professional solutions are commonly used by tax preparers and therefore include workflow features — such as handling installment agreements or electronic payment indicators — that consumer apps may not expose in the same way ^{[9] [10]}.

3. IRS rules and the single most important constraint: original‑return method

The IRS has publicly stated that Form 1040‑X can be filed electronically for the current and two prior tax periods and that tax‑software vendors can transmit electronic amended returns, but it also makes clear that if the original return was paper filed, the amended return generally must also be paper filed — a constraint that renders some e‑file options unavailable for certain taxpayers ^{[1] [3] [2]}. Multiple vendors mirror that restriction in practice: platforms often require that the original return was accepted electronically on the same platform before permitting an e‑filed amendment, creating “platform‑lock” effects ^{[8] [4]}.

4. Tradeoffs, fees, and operational caveats readers should expect

Advertised e‑file capability is not uniform: some services bundle amended returns into paid tiers or charge a discrete fee for 1040‑X (FreeTaxUSA’s cited fee is an example), some limit e‑file amendments to returns originally filed on that service (eFile.com, TurboTax), and pro software may offer broader technical support but require preparer access or licenses ^{[5] [8] [4] [9]}. The IRS notes direct deposit refunds are available for electronically filed 1040‑X for recent years, a functional improvement, but processing time still can be lengthy and some forms/years are no longer e‑eligible ^{[2] [10]}.

5. Bottom line and recommended decision frame

For taxpayers seeking to e‑file a 2025 Form 1040‑X, the IRS authorizes e‑filing via tax software ^{[1] [2]}, and named vendors that report support include TurboTax (with original‑e‑file caveat), FreeTaxUSA, Express1040, TaxHawk, eFile.com (when original return was filed there), TaxSlayer Pro, and Drake Tax ^{[4] [5] [6] [7] [8] [9] [10]}. The decisive questions for a filer are whether the original return was e‑filed or paper filed, whether the filer used the same platform originally, and whether any vendor fees or professional‑access requirements apply; those factors determine which of the advertised e‑file options will actually be usable ^{[3] [8] [5]}.
