The IRS will now allow practitioners representing taxpayers with IRS matters to obtain 30 client transcripts per call to the Practitioner Priority Service (PPS) hotline (although it can of course take a lifetime to actually get through to someone via the hotline).  The new limit was announced in IR-2021 (Nov. 16, 2021).  The previous transcript limit was 10 per call to the PPS line.  (The limit of five clients per call remains the same.)

The new 30 transcript limit applies to the most commonly requested IRS transcripts: tax return, tax account, wage and income, record of account, and verification of non-filing letter.  The old 10 transcripts per PPS call applies to all other transcripts.

The PPS hotline can be reached at (866) 860-4259 by any tax professional – attorneys, CPAs, enrolled agents – with valid third-party authorizations on file with the IRS CAF Unit (although it would be wise to have your F2848 or other power of attorney/third-party authorization handy and ready to fax to the PPS representative, as doing so will save time and avoid the need for another call to PPS in the event the presentative cannot locate the authorization on the IRS's system, a common problem).
