Entries on certain lines of Form 2848 will cause the authorization to be classified as “modified” when recorded on the Centralized Authorization File (CAF). When a Form 2848 is classified as “modified” on the CAF, appointed representatives on the forms are unable to:

  • Access the Transcript Delivery System (TDS) to obtain IRS transcripts of the represented taxpayer for the tax matters, tax forms, and tax periods specified on each form, or
  • Use IRS Tax Pro Account to establish an installment agreement for a represented taxpayer for the affected tax matters and periods.

A Form 2848 is “modified” in these instances:

  • Line 5a, Additional acts authorized, grants any authorization other than disclosure to third parties, substitute or add representative(s), or sign a return, or
  • Line 5b, Specific acts not authorized, limits the representative’s authority as described on line 5b.

To prevent these issues, a Form 2848 must not contain check marks or entries in either lines 5a or 5b that will be considered modified.

Note: Checking the box on line 4 will result in the authorization not being recorded on the CAF. Taxpayers and representatives should never check line 4 unless Form 2848 is, in fact, a specific- use form, and they should never file Forms 2848 designated for specific use with a CAF Unit, as the forms are not meant to be recorded on the CAF. See the Instructions for Form 2848 for examples of specific use, including the most common ones.
