Are there any forms that the IRS is not accepting yet for e-filing?
The IRS continuously updates its e-filing capabilities, but not all forms are available for electronic submission. Some forms require paper filing due to specific requirements, such as the need for physical signatures, attachments, or complex reporting structures.
Forms Permanently Ineligible for E-Filing
Certain forms must always be submitted via paper mail, as the IRS electronic system does not currently support them:
- Form W-7: Application for IRS Individual Taxpayer Identification Number (ITIN).
- Form 8453: U.S. Individual Income Tax Transmittal. This is used to send paper attachments after e-filing your main return; the form itself must be mailed.
- Form 14039: Identity Theft Affidavit.
- Form 1040-V: Payment vouchers (must be printed and mailed with a check/money order).
- Form 1040-ES: Estimated tax payment vouchers.
Other E-Filing Restrictions
- Prior Year Returns: E-filing is only supported for the current year (2025) and two prior years (2024 and 2023). Any federal return for Tax Year 2022 or earlier must be filed on paper.
- Direct File Program: Note that the IRS Direct File program, which was a pilot for direct free filing, has been shut down for the 2026 season.
- Dual-Status Returns: Taxpayers who were both a resident and nonresident alien during 2025 generally cannot e-file and must use paper forms.
