Form 2848 vs. Form 8821: One Authorizes You to Act. One Doesn’t.

Form 2848 vs. Form 8821: One Authorizes You to Act. One Doesn’t.
Form 2848 and Form 8821 look alike. What each authorizes — and what each doesn’t — determines whether you can act for your client or only watch.
From the Desk
Two developments landed in the five days before this issue went out, and both point at the same weak spot in practitioner authorization.
On July 8, the IRS quietly posted new guidance on how a common Form 2848 entry can silently lock you out of your own client’s transcripts. And the National Taxpayer Advocate’s 2025 Annual Report to Congress named CAF breakdowns one of the ten most serious problems taxpayers face — with practitioners bearing the practical cost.
This issue covers both: the form you actually need, and the traps, old and brand new, that keep even careful filers from getting it right.
