2. Step-by-Step Claim Process

Follow these exact steps to ensure your electronic tentative refund application is accepted.

Step 1: Prepare Your Core Application

• Required Form: Complete either Form 1045 (Individuals/Estates/Trusts) or Form 1139 (Corporations) with all supporting schedules.
• Determine Refund Amount: Calculate your net operating loss, unused general business credit, net capital loss, or other eligible carryback amount. These figures go on lines 2a-2f of Form 8453-TR.
• Pitfall Alert: Errors on Form 1045/1139 will cause your entire submission to be rejected or delayed. Double-check math and ensure you meet the 1-year filing deadline.

Step 2: Complete Form 8453-TR

• Part I: Check box 1a (Form 1045) or 1b (Form 1139). Transfer the correct dollar amounts from your application to lines 2a-2f.
• Part II (Taxpayer Declaration): This is your digital signature.
  • Choose a PIN method: Authorize your ERO to enter a PIN for you, or elect to enter your own PIN.
  • Physically sign and date the form. It must be scanned.
• Part III (ERO/Preparer Declaration): Your tax professional completes this. If you are self-filing without an ERO, leave this part blank.

Step 3: Submit Your Package

• Submission Method: Your ERO or transmitter software will scan the signed Form 8453-TR into a PDF and attach it to the electronic Form 1045/1139 file.
• Do Not Mail Paper Copies. The entire point of Form 8453-TR is for e-filing. Mailing a paper copy will create confusion and delays.
• Pitfall Alert: Ensure your ERO/transmitter submits the signed PDF. An unsigned form will result in rejection.

Step 4: After Submission

• Processing Timeline: The IRS aims to process tentative refunds within 90 days. However, the instructions note that “Some refunds may be delayed because of compliance reviews.”
• Status Updates: By signing Part II, you authorize the IRS to provide your ERO/transmitter with status, delays, or rejection reasons. Check with them first.

4. Pro Tips & Common Rejection Reasons

Maximize Your Refund & Avoid Delays:

• File Electronically: E-filing with Form 8453-TR is the fastest way to get a tentative refund, often within 90 days.
• Opt for Direct Deposit: Ensure your banking details are correctly listed on Form 1045/1139 for the fastest payment.
• Review Before Signing: Verify all amounts on Form 8453-TR match Form 1045/1139 exactly. Inconsistencies cause rejections.
• Keep Copies: Retain a copy of the signed Form 8453-TR, Form 1045/1139, and all supporting documents.

Most Common Reasons for Denial/Delay:

1. Missing/Wet Signature on Form 8453-TR: It must be physically signed before scanning.
2. Form 8453-TR Submitted for a Paper Return: It is only for e-filed Forms 1045/1139.
3. Incorrect or Blank Lines in Part I: Amounts must match the main application form.
4. Missing the 1-Year Filing Deadline: The law is strict; late applications are denied.
5. Compliance Review: The IRS may flag your return for further examination, delaying the refund beyond 90 days.

Appeal Procedure: If your application is denied, you will receive a notice explaining why. You typically cannot appeal the denial of a tentative refund itself, but you can still file a regular claim for credit or refund (e.g., Form 1040-X) after the denial, subject to statute of limitation rules.
