How to Fax a Direct Deposit Authorization Form

A direct deposit authorization tells an employer or paying organization to send pay or benefits electronically to a named bank account, listing the account holder, the bank's routing number, the account number, and whether it is checking or savings. Employees submit it when they start a job or change banks, and it is usually paired with a voided check or a bank letter that confirms the account details. Payroll departments frequently accept the signed form by fax so a new hire's pay can be routed before the next cycle without waiting on mail. A faxed authorization arrives as a fixed, dated image payroll can attach to the employee's record and enter into the payment system.

Why this form is faxed

Payroll runs on a fixed cycle, so faxing a signed direct deposit form gets it to payroll before the cutoff that decides whether the first electronic payment lands on time or arrives as a paper check. A faxed form also reaches payroll as a single fixed image with the voided check attached, matching how they record and enter the account details.

Where it goes

A direct deposit authorization goes to the employer's payroll or HR department using the fax number they provide on the form or in your onboarding paperwork. Confirm that number with your payroll contact before sending, since larger employers may route new hires and changes to a shared service center. Do not send banking details to any number you cannot tie back to your employer.

How to fax Direct Deposit Authorization

  1. 1Complete the form with your name, the bank routing number, the account number, and whether the account is checking or savings
  2. 2Attach a voided check or a bank letter if the form or employer requires it to confirm the account
  3. 3Verify each digit of the routing and account numbers, since a transposed number can misdirect your pay
  4. 4Sign and date the authorization, then confirm the payroll or HR fax number with your payroll contact
  5. 5Log in to Send FAX Mail, upload the form and any voided check as one clear PDF, enter the confirmed number, and send
  6. 6Save the transmission confirmation as proof you submitted the authorization before the payroll cutoff

Handling sensitive information

A direct deposit form exposes your bank routing and account numbers, which are enough for someone to attempt to redirect your pay or initiate withdrawals. Payroll data is protected personal information, and the Gramm-Leach-Bliley Act governs how the receiving financial institution must safeguard it, so send the form only to a payroll number you have confirmed rather than one from an unexpected email.

Recent updates

  • Federal interoperability rules keep pushing healthcare past the fax machine

    CMS has advanced a series of interoperability rules that press hospitals, payers, and providers toward electronic data exchange and standardized claims attachments. The direction of travel is clear: paper and analog fax workflows are being replaced by digital transmission that carries an auditable record — which is exactly what a cloud fax with delivery confirmation provides for offices not yet on a full EHR pipeline.

  • Federal agencies still write fax into new rules and notices

    The Federal Register — the daily journal of U.S. federal rulemaking — regularly publishes rules and notices that reference fax as an accepted or required submission channel for filings with agencies like the IRS, SSA, and CMS. That is why fax remains a live requirement for many official forms even as electronic portals expand.

  • Healthcare breach reporting keeps document handling under scrutiny

    Ongoing reporting on HIPAA breaches and OCR settlements underscores how much scrutiny falls on how medical documents are stored, sent, and received. Sending records through a controlled, access-logged channel rather than an unmanaged machine reduces the mishandling risks that show up repeatedly in breach analyses.

Faxing Direct Deposit Authorization — FAQ

Many employers ask for a voided check or an official bank letter so they can confirm the routing and account numbers exactly and avoid entering a mistyped digit. If your form requests one, fax it on the same page or right behind the authorization. If your bank offers a pre-filled direct deposit letter, that works in place of a voided check.

That depends on your employer's payroll calendar and whether they pre-note the account with a test transaction first, which can take a pay cycle or two. Fax the form well before a payroll cutoff so it is processed for the earliest possible cycle. Ask payroll which paycheck will be the first to deposit electronically so you know when to expect it.

Faxing sends the form straight to payroll as a fixed image rather than leaving your account numbers in an email thread, but the safeguard is confirming the destination. Because scammers sometimes pose as employees to redirect pay, employers often verify a change request, and you should send only to a payroll number you can independently confirm. That two-way check protects your paycheck.

If a payment already went out to a wrong-but-valid account it can be difficult to recover, so accuracy up front matters more than speed. If you catch the error before the next payroll run, fax a corrected authorization immediately and call payroll to flag the change. Keep your send confirmations so you can show which version payroll should be acting on.
