What Form 1045 is and how it works

Form 1045, Application for Tentative Refund, is an IRS application used to request a tentative refund based on eligible tax adjustments. The applicant provides taxpayer information, the applicable tax-year details, the adjustment or carryback calculation, and supporting schedules required by the IRS instructions. A tax professional or authorized representative can prepare the PDF, route assigned fields for review and signature, and retain the completed application with its audit trail in signNow. Electronic signing supports record handling under ESIGN and UETA, but does not replace IRS submission instructions or tax advice.

Best practices for Form 1045 preparation

Accuracy checks, role separation, audit evidence, and IRS review help keep a Form 1045 workflow organized without altering the tax form’s requirements.

Verify every Form 1045 field

Upload the current Form 1045 document and compare every detected field with the IRS instructions before sending. Confirm taxpayer details, tax-year information, refund calculations, supporting schedules, and signer assignments rather than relying only on automated field recognition.

Assign preparation and signature roles

Separate preparation from authorization by assigning fields to the responsible preparer and signer. Require the signer to review the completed application, confirm intent, and finish all required signature and date fields before completion.

Preserve the completion evidence

Download the completed Form 1045 and its signNow audit trail together. Check timestamps, signer identity evidence, and completion status before transferring the package to the tax records repository.

Confirm IRS submission requirements

Compare the completed application against the applicable IRS filing instructions before submission. An electronic workflow organizes signatures and records, but it does not replace required attachments, filing channels, or tax-professional review.
