For tax professionals, access to timely and accurate IRS data is not a convenience — it is essential to effective representation, taxpayer rights and voluntary compliance. At the center of that access sits the Internal Revenue Service's Centralized Authorization File, the system responsible for recording powers of attorney (Form 2848) and tax information authorizations (Form 8821).
Yet today, CAF processing has become one of the most significant operational bottlenecks in the tax administration ecosystem. Despite years of awareness and substantial resources devoted to the problem, CAF delays continue to undermine service, increase costs for the IRS and frustrate taxpayers and practitioners alike.
When an authorization is recorded in CAF, tax professionals can obtain transcripts, receive IRS notices and represent taxpayers efficiently — often without involving IRS phone assistors. When CAF processing breaks down, the entire system feels the ripple effects:
- Tax pros begin to resubmit authorizations multiple times.
- Firms pivot to already-strained IRS phone lines.
- Resolution of taxpayer issues is delayed, sometimes for weeks.
- Taxpayer rights to representation are effectively put on hold while IRS-mandated response windows continue to count down.
Historically, the IRS service standard for CAF processing was five days or less. That standard is now routinely missed. Over the last two years, processing times for Forms 2848 and 8821 have ranged from one day to more than 26 days, with the current average hovering around 10 business days — and increasing after filing season.
The scale of the problem
The volume tells the story. In 2025 alone, nearly 7 million authorizations were filed — a dramatic increase over the past five years. According to the National Taxpayer Advocate, the IRS spent more than 972,000 staff hours (or approximately 500 staff years) processing authorizations through the CAF unit in a single year.
Much of this growth is driven by large tax service providers, which file Forms 8821 at scale to gain access to IRS transcripts via the Transcript Delivery System. This is a good thing for tax administration. Transcripts allow firms to quickly resolve notices, answer client questions and monitor compliance without calling the IRS.
But the CAF system remains largely manual, requiring IRS employees to key-enter authorization data — even when forms are uploaded electronically. As authorization volumes grow, this labor-intensive approach becomes increasingly unsustainable.
Business CAF: A step forward—but not a solution (yet)
The IRS's recent rollout of Business CAF is a recognition that the current model does not scale. In concept, Business CAF could significantly reduce CAF workload by allowing firms to act as a single designee rather than listing multiple individual employees on each authorization.
That is an important shift. Multiple individual designees:
- Inflate CAF processing time due to repetitive data entry and multiple resubmissions;
- Create security and privacy risks when employees leave firms; and,
- Require constant authorizations updates to reflect staff changes.
A properly functioning Business CAF could eliminate much of this inefficiency.
Unfortunately, in its current form, Business CAF does not yet solve the problem, and adoption will remain limited unless several critical issues are addressed:
1. Barriers to access through a Business Tax Account. To use Business CAF, an authorized person must first obtain "designated official" status within the IRS Business Tax Account. DO status is limited to firm employees who can legally bind the firm. Many firms report significant difficulty completing this process — even when all requirements are met. Without designated official status, Business CAF is effectively unavailable.
If firms cannot reliably access the system, they cannot use it — no matter how promising the concept.
2. No delegation of management authority. Currently, the designated official may allow others to view taxpayer data through the Tax Pro Account but cannot delegate authority to manage the Business CAF itself.
This is a major operational flaw. In many firms, individuals who qualify as designated officials are owners or executives — not the personnel who manage daily authorization workflows. Without the ability to delegate administrative control, Business CAF becomes impractical for midsized and large firms.
3. No e-Services transcript access for Business CAF authorized users. This is the most serious deficiency — and the one most likely to prevent adoption altogether.
Authorized users under Business CAF cannot access transcripts through TDS. Firms rely on transcript access to serve clients efficiently and avoid phone contact with the IRS. Without TDS access, firms have little incentive to move away from multiple individual designees — even if Business CAF reduces CAF workload for the IRS.
Until transcript access is enabled for Business CAF authorized users, Business CAF will not meaningfully reduce authorization volume or processing time.
4. Continued manual processing of mass 8821 submissions. Authorization volume has surged, yet CAF processing remains largely manual. Even when firms submit 8821s electronically through the IRS's Submit 2848/8821 tool, IRS staff must still manually input the data into CAF.
Large submitters have proposed simple, immediately deployable solutions, such as secure bulk uploads that allow taxpayer and designee data to populate directly into CAF — eliminating millions of keypunches. These solutions would reduce costs, shrink processing times and free IRS resources, yet they remain largely untapped.
The broader impact on compliance and taxpayer rights
More than half of all taxpayers rely on a tax professional to file their tax returns. Even more rely on a tax pro when an issue arises with the IRS. When CAF delays prevent those professionals from acting, voluntary compliance suffers. Taxpayers wait longer to resolve issues, representation is delayed, deadlines are missed, and IRS resources are consumed by avoidable phone calls and duplicate submissions.
CAF is not just an administrative function — it's a critical bridge between the IRS and the tax professional community (and the taxpayers they serve). When that bridge is congested, everyone pays the price.
A call for practical modernization
The IRS deserves credit for acknowledging the CAF problem and introducing Business CAF. But modernization must be practical, not just conceptual. Without reliable access, delegated management, transcript availability and true automation for mass submissions, the CAF conundrum will persist.
Meaningful progress will require collaboration with tax professionals as well as with firms that operate at scale. The payoff is substantial: faster service, lower costs, improved security, stronger compliance and a better experience for taxpayers and the IRS alike.
Until then, CAF processing remains one of the most significant — and solvable — challenges in tax administration.
