The IRS has announced on its website that for estate tax returns (Forms 706) filed on or after June 1, 2015 that account transcripts will substitute for an estate closing letter. Registered tax professionals that use the Transcript Delivery System (TDS) can use the TDS as can authorized representatives that use Form 4506-T, and requests will be honored if a Form 2848 (Power of Attorney) or Form 8821 (Tax Information Authorization) is on file with the IRS. The IRS provided instructions and noted that Transaction Code 421 on the website will indicate that the Form 706 has been accepted as filed or that the exam is complete. IRS also noted that a transcript can be requested by fax or by mail via Form 4506-T to be mailed to the preparer's address. Certain items are necessary to document that the preparer has the authority to receive the transcripts - letters testamentary (or equivalent), Form 56 (Notice Concerning Fiduciary Relationship), Form 2848 and any other documentation that authorizes the party to receive the information. The IRS noted that its decision whether or not to audit any particular Form 706 is usually made four to six months after the Form 706 is filed, and that the transcript should not be requested until after that time period has passed.
