Form 4506-C Rejection Reasons:

    • The 4506C form, or an item on the form, is illegible, missing, or incomplete.
    • The 4506C form is altered - there is evidence that an entry was changed with white out, lined through, or written-over, or if there is any indication of cutting and pasting.
    • Flagged for Identity Theft or Fraud - Taxpayer must contact the IRS Identity Protection Security Unit directly at 800-908-4490.
    • Line 1a, 1b & 2a, 2b – Name and/or SSN does not match what is on IRS Master Account for the taxpayer the
      order is for.
    • Line 3 & 4 – Address is illegible, incomplete, or does not match information on the taxpayer’s IRS Master
      Account.
    • POA documentation did not Authorize with information on taxpayer’s IRS Master Account.
    • Address Rejections:
      • Address(es) on 4506C is not the Tax Return Filing Address(es) for the Years and Product being Ordered
      • Address(es) on 4506C is not the Wage information Address(es) for the Years and Product being Ordered
      • 1040 and W2/1099 can have different address(s).
      • The Address does not match exactly how it appears on the Tax Returns for each year Ordered.
      • Even if the 4506C reflects the Tax Return address(s), the address needs to be what the IRS has on file for the Taxpayers IRS Master Account.
      • The Current Address on Line 3 needs to be the most recent year being ordered. Not the most Current Address the Taxpayer has lived.
      • The Previous Address on Line 4 needs to the other Address for other years ordered, if it is different than Line 3.
      • Only one Address per line. If a Taxpayer has different Addresses for all the years being ordered, a separate 4506C may need to be created with a second order.
      • Legibility is also key. If the IRS cannot read the Information, the 4506C will be Rejected by the IRS.

Preparing a tax-transcript request in XedaLink

These steps cover the order screen, not instructions for completing or signing the IRS form. Confirm the current form requirements and KCB participant details before submitting.

  1. From Main, expand Employment/Income/Asset Verification and select Order Tax Transcript.
  2. Confirm Branch and User, Loan Identifier, and the notification recipient.
  3. Select Personal or Business. The November 2026 screen review covered the Personal view only.
  4. Complete the requested taxpayer and, when applicable, spouse information. Review current and prior tax-return address fields against the authorization and current instructions.
  5. Select Tax Forms, Transcript Type, and Year(s) Requested. Check every requested year and product against the signed authorization. Use Add Transcript only when another authorized transcript is needed.
  6. Under 4506-C Delivery Method, upload the signed form and answer whether it was electronically signed. The inspected upload control required a PDF or TIFF smaller than 2 MB; follow the current screen if its limits change.
  7. Review the complete request, supporting documents, and payment choice before submitting.

The blank Personal preparation form was reviewed November 7, 2026 without uploading a form or requesting a transcript. This review did not revalidate every legacy form rule, phone number, or participant detail above. Ask KCB about current requirements if anything differs from the form or screen.

For a returned rejection, see 4506-C IRS Rejection Codes and contact KCB for the appropriate next step. Do not alter a signed authorization to make it match a different request.
