Use this guide if you run or support a Low Income Taxpayer Clinic, a Student Tax Clinic Program, or you supervise students or recent law grads. I will walk you through what Form 13424‑P does, how it ties to Form 2848, the pitfalls clinics hit, and how to keep everything compliant and on time.
Key Takeaways
- Form 13424‑P is the IRS Application for Special Appearance Authorization that clinics use to request permission for students or qualified law graduates to appear in a specific taxpayer matter under supervision. It is posted as the September 2021 revision on IRS.gov.
- A special appearance letter comes from the LITC Program Office under authority in Circular 230 section 10.7(d) and Delegation Order 25‑18. Students or qualified law grads are then allowed to represent a taxpayer in that matter, under supervision.
- You still use Form 2848 to record representation on the CAF, and you attach the special appearance letter to that 2848. Think of 13424‑P as the request, and 2848 as the authorization on the taxpayer’s account.
- 13424‑P sits under OMB Control No. 1545‑1648 as part of the LITC information collections. The OMB docket shows 2025 activity that modified the collection, so check you are using the current materials even though the posted PDF shows Sep 2021.
- The form is short, but accuracy matters. Incomplete clinic details, unclear supervision, or vague case descriptions slow approvals and can jeopardize a deadline.
What Form 13424‑P Actually Does
Form 13424‑P is the IRS’s “Application For Special Appearance Authorization.” Clinics use it to ask the LITC Program Office to approve a student or qualified law graduate to appear in one taxpayer’s case, subject to limits in the approval letter and the clinic’s supervision model. The IRS lists the form with a September 2021 revision date, and the current PDF is available in the IRS static files directory.
This is not a general practice credential and not a replacement for Form 2848. IRS practice rules explain that students and qualified law graduates can be authorized for special appearances, and the IRM tells you to attach the special authorization letter to a properly completed Form 2848 for the periods and forms at issue.
Put simply, 13424‑P asks for the permission, the LITC Program Office issues the permission letter, and Form 2848 records who can talk, receive information, and act for that taxpayer for the defined matter.
If you are a CPA, attorney, or enrolled agent who already has full practice rights, you do not need 13424‑P for yourself. You file a standard 2848, period. The special appearance route exists to let supervised students and qualified law grads help real taxpayers, which is a core LITC and STCP mission.
When To Use Form 13424‑P, And When Not To
Use 13424‑P when
- A student or qualified law graduate in an LITC or STCP will handle a defined IRS interaction, such as an audit conference, interview, or case discussion for specific periods and forms.
- The clinic will supervise that student or law grad, and the LITC Program Office has authority to issue the letter under Circular 230 and Delegation Order 25‑18.
- You intend to submit a Form 2848 for the taxpayer, attaching the special appearance letter so the representative is visible to IRS personnel and the Centralized Authorization File for the relevant matter.
Do not use 13424‑P when
- A fully authorized practitioner, like a CPA, attorney, or EA, is representing the taxpayer. Use Form 2848 without the student authorization pathway.
- You only need information access and no representation. Use Form 8821 instead of 2848 or a special appearance.

Why Clinics Run Into Trouble
From what I have seen, hiccups fall into a few patterns, all fixable with clear SOPs.
- Vague case descriptions, for example, “audit help,” rather than the exact form and tax period.
- Missing supervision details, which leaves the reviewer unsure how the student is overseen.
- Timing assumptions, clinics expect same week turnaround when workload is high.
- Treating 13424‑P as a substitute for 2848, which stalls the case because IRS employees still look for a CAF authorization.
Accountably’s core belief shows up here too. Capacity without structure creates chaos. If your clinic or partner firm supports pro bono matters, create a one page checklist that ties 13424‑P, the anticipated IRS interaction, the supervising practitioner, and the downstream 2848 steps together. That single page prevents rushes and rework.
Step‑By‑Step, How To Complete Form 13424‑P With Confidence
Below is a practical flow that has worked well for clinics we have supported. Match it to your internal processes and add your own routing details.
1) Confirm you actually need a special appearance
- Is the representative a student or a qualified law graduate who will be supervised.
- Is there a specific matter, tax form, and period.
- Will you file a Form 2848 for the taxpayer and attach the letter once issued.
2) Gather clinic and representative details
- Clinic name, address, program type, and supervising practitioner with full credentials.
- Student or law graduate’s full name and contact details, plus expected start date of representation and scope.
- Any internal IDs your clinic tracks against the case. The IRS lists 13424‑P in the forms index and hosts the PDF in its static files directory. Download the current file before each use.
3) Describe the taxpayer matter precisely
- Identify the taxpayer, the tax form, and the tax periods under discussion.
- Summarize the IRS interaction you expect, for example, “Exam conference for Form 1040, tax years 2022 and 2023.”
- Note any constraints, like a scheduled phone conference date.
4) Verify authority and current references
- Circular 230 allows special appearances and Delegation Order 25‑18 delegates this authority to the LITC Program Office. Confirm your clinic has the right supervision model in place.
- Check the OMB docket for 1545‑1648 if you document compliance metadata. The June 2025 filing shows modifications to the collection that includes 13424‑P. The posted PDF remains the Sep 2021 revision as of December 19, 2025, which is fine to use unless IRS posts an update.
5) Submit per LITC Program Office guidance
The IRM notes that the Program Office issues the special appearance letters and that LITC Analysts guide clinics to the correct forms and intake channel. Follow your assigned Analyst’s instructions. If you are a student or law grad with independent practice rights, you usually should not request a special appearance, you should use your standard CAF route.
6) Record representation on the CAF
Once the letter arrives, prepare and file Form 2848 for the taxpayer, attach the special authorization letter, and ensure the scope and periods match what the letter allows. This makes the authorization visible to the IRS and avoids friction during calls.
Timing, Revisions, And What Changed In 2025
- The IRS form listing still shows “Sep 2021” for 13424‑P, and the IRS static file is dated September 28, 2021. That is the correct PDF as of today.
- On the OMB side, the LITC information collection under Control Number 1545‑1648 was updated in 2025. The docket ICR 202505‑1545‑013 shows 13424‑P marked “Modified,” with a supporting statement posted in June 2025. These updates typically address burden, routing, or collection details, not always visible on the face of the one‑page PDF.
Practical takeaway, always download the current 13424‑P from IRS.gov before you complete it and keep a copy of the OMB entry in your internal compliance notes if your organization tracks that level of detail.
Common Pitfalls And How To Avoid Them
Pitfall 1, Treating 13424‑P like a mini‑2848
13424‑P does not create representation on the taxpayer’s account by itself. You must submit a 2848 with the letter attached. If IRS personnel cannot see a valid 2848, they will not discuss the case, even if your student is otherwise authorized. Fix this with a simple two‑step checklist.
Pitfall 2, Vague scope
Write the matter clearly, for example, “Form 1040 exam, TY 2023, Schedule C gross receipts.” Ambiguity slows review.
Pitfall 3, Missing supervision details
The Program Office needs to know who supervises the student or law grad and how. List the supervising attorney, CPA, or EA with contact information and the supervision structure referred to in your clinic’s policies.
Pitfall 4, Timing assumptions
Turnaround depends on workload. Build a modest buffer. If a date is set, include it in the application so the Analyst understands the urgency.
Real‑World Workflow Tips
- Create a one page intake that pairs 13424‑P with a draft 2848, so the letter and the CAF filing move in sync.
- Use a naming convention for files, for example, “TaxpayerLast_First_13424P_YYYYMMDD.pdf.”
- Keep a short script for IRS calls that confirms both the CAF recording and the letter, for example, “We have a 2848 on file for TY 2023 and a student special appearance letter dated October 3, 2025.”
- Train students to reference the IRM sections on representation for credibility during interactions.
A quick brand note for context, Accountably helps CPA and EA firms build disciplined delivery systems. If your firm partners with a clinic, you can borrow the same SOP principles here, standardized workpapers, versioned forms, and early review notes, which cut time in review and protect deadlines without burning out your team.
FAQs
Does 13424‑P let a student represent a taxpayer without Form 2848
No. The special appearance letter authorizes the student or qualified law grad to practice for that matter under supervision, but IRS personnel still expect a valid Form 2848 on file for the taxpayer with the letter attached.
Who issues the special appearance letter
The LITC Program Office, under Circular 230 section 10.7(d) and Delegation Order 25‑18. The IRM describes this process and the analyst support clinics receive.
Can a CPA or attorney use 13424‑P for a one‑time appearance
No. Practitioners with full practice rights use Form 2848, not 13424‑P. The one‑time special appearance framework is for students and qualified law graduates working in LITCs and STCPs under supervision.
What is the current revision of 13424‑P
IRS.gov lists Form 13424‑P with a September 2021 revision and hosts the PDF in its static directory. Check before each use, since the OMB docket shows the overall collection was modified in 2025 even though the face of the form still shows 9‑2021.
Where can I read more about representation rules
Start with the IRS 2848 page and the IRM sections on representation, which explain the difference between 2848 and 8821 and how special appearance authorizations fit.
