All information comes directly from official IRS sources, including the Form 8453-WH instructions, About Form 8453-WH page, and 2025 Instructions for Form 1042.

What Is IRS Form 8453-WH?

Form 8453-WH is the official E-file Declaration used exclusively for electronically filed Form 1042. Withholding agents (or their authorized representatives) sign it under penalties of perjury to confirm that:

  • The electronic return data is true, correct, and complete.
  • The transmitted information matches the signed declaration.
  • Transmission through an Electronic Return Originator (ERO), Intermediate Service Provider (ISP), or third-party transmitter is authorized.

The form is not mailed as paper. Instead, you scan the signed original into a PDF and transmit it electronically with your Form 1042 via IRS-approved tax preparation software that supports MeF for business returns.

Key Fact: Electronic filing of Form 1042 has been mandatory in many cases since tax year 2023 (returns filed in 2024). Requirements apply to financial institutions and withholding agents who file 10 or more information returns in a calendar year (or partnerships with >100 partners). Paper filing is generally no longer accepted for those who meet the thresholds.

Purpose of Form 8453-WH

According to the IRS, Form 8453-WH serves four main functions:

  1. Authenticate the electronic Form 1042 — It verifies the return under penalties of perjury.
  2. Authorize transmission — Allows an ERO (if used) or ISP to send the return via a third-party transmitter.
  3. Handle online filings without an ERO — Required when filing directly through an ISP/transmitter.
  4. Consent to electronic funds withdrawal (direct debit) — For paying any balance due on Form 1042, line 69.

Important Note: If you use an ERO and prefer a 5-digit PIN signature, you can skip Form 8453-WH and use Form 8879-WH (E-file Authorization for Form 1042) instead. Many software providers default to one or the other.

Who Must File Form 8453-WH?

You must file Form 8453-WH if you are:

  • Filing Form 1042 electronically through an ISP and/or transmitter and not using an ERO.
  • Using an ERO but choosing the paper declaration method (instead of PIN via Form 8879-WH).

Withholding agents include U.S. persons or entities that withhold tax on payments to foreign persons (e.g., dividends, interest, rents, or other FDAP income subject to chapters 3 and 4 withholding).

Exemptions/Alternatives: EROs can use Form 8879-WH for PIN-based signing. Always check your software options.
