Last Updated May 14, 2025

Filing a U.S. tax return electronically requires several key documents, including your Social Security number or Individual Taxpayer Identification Number (ITIN), W-2 forms from employers, and 1099 forms reporting other income sources. You must also have records of any deductions or credits you plan to claim, such as mortgage interest statements, education expenses, or health savings account contributions. Accurate and complete documentation ensures the IRS processes your electronic submission efficiently and minimizes the risk of errors or audits.

What Documents Are Required for Filing a U.S. Tax Return Electronically?

Number Name Description
1 IRS Identity Protection PIN (IP PIN) Filing a U.S. tax return electronically requires submitting an IRS Identity Protection PIN (IP PIN) for taxpayers who have been assigned this unique six-digit code to prevent identity theft and fraud. Taxpayers must enter their IP PIN on the tax return to verify their identity and ensure the electronic submission is accepted by the IRS system.
2 Digital Signature Certificate (DSC) A Digital Signature Certificate (DSC) is mandatory for certain taxpayers and authorized representatives to electronically file U.S. tax returns, ensuring secure and authenticated submissions. This certificate uses encryption technology to validate the identity of the filer and maintain the integrity of the electronic documents submitted to the IRS.
3 Taxpayer Authentication Records Taxpayer authentication records required for filing a U.S. tax return electronically include a valid Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN), along with electronic signatures such as a Personal Identification Number (PIN) or Adjusted Gross Income (AGI) from the prior year's tax return. The IRS mandates these records to verify the identity of the taxpayer and ensure secure e-filing compliance.
4 Preparer Tax Identification Number (PTIN) Filing a U.S. tax return electronically requires the tax preparer to have a valid Preparer Tax Identification Number (PTIN), which must be included on all electronically submitted returns. The PTIN ensures compliance with IRS regulations and enables accurate tracking and verification of tax preparers involved in the electronic filing process.
5 e-Filing Acknowledgment Receipt The e-Filing Acknowledgment Receipt is a crucial document confirming the IRS has accepted your electronically filed tax return, typically containing a unique submission ID and timestamp. Taxpayers should retain this receipt as proof of filing and for reference in any subsequent IRS communications or audits.
6 Electronic Filing Identification Number (EFIN) The Electronic Filing Identification Number (EFIN) is a crucial requirement for tax professionals submitting U.S. tax returns electronically, as it verifies the authorized e-file provider's identity with the IRS. To obtain an EFIN, applicants must submit a complete Form 8633 and pass a suitability check, ensuring compliance with IRS regulations and secure electronic submissions.
7 Summarized Virtual Currency Transaction Records Summarized virtual currency transaction records, including dates of acquisition and sale, transaction amounts, and fair market values at the time of each transaction, are essential for accurately reporting capital gains or losses on a U.S. tax return filed electronically. The IRS requires taxpayers to provide these detailed summaries to ensure compliance with tax laws governing digital assets when submitting Form 8949 and Schedule D through e-filing platforms.
8 IRS Form 8879 (e-file Signature Authorization) IRS Form 8879 (e-file Signature Authorization) is essential for electronically filing a U.S. tax return as it authorizes the electronic submission and serves as the taxpayer's digital signature. This document must be accurately completed and signed before e-filing to ensure compliance with IRS e-filing regulations and avoid processing delays.
9 Two-Factor Authentication Credentials Two-factor authentication credentials are essential for securely accessing the IRS e-file system when filing a U.S. tax return electronically, ensuring protection against unauthorized access. Taxpayers must provide a combination of something they know, such as a password or PIN, and something they have, like a mobile device or authentication app, to comply with IRS security protocols.
10 Third-Party Designee Authorization Form The Third-Party Designee Authorization Form (IRS Form 8879) is essential for taxpayers who authorize an individual other than themselves, such as a tax preparer, to electronically file their U.S. tax return. This form grants the designated person permission to sign the return electronically and allows the IRS to discuss the return with that individual if necessary.
