What surprised them was that a plan year change is not just a calendar tweak. You need IRS consent in many cases, and the filing has moving parts, from user fees to actuarial effects. That is exactly where IRS Form 5308 comes in.
If you change a plan year or trust year for a qualified retirement plan, the change generally takes effect only if the IRS approves it, which you request on Form 5308 under IRC §412(d)(1).
Key Takeaways
- Form 5308 is the IRS request to change a retirement plan or trust year under IRC §412(d)(1). Approval is required for many plans before the new year applies.
- You file by the end of the short plan year, include a clear business reason, and attach supporting plan documents and actuarial information where relevant.
- Mail the package to IRS EP Letter Rulings in Kentucky, with different addresses for USPS and private delivery services.
- Some plan types qualify for automatic approval and do not need to file, for example profit‑sharing and stock bonus plans, if they meet the revenue procedure conditions.
- As of December 3, 2025, the IRS “About Form 5308” page confirms the form’s purpose and current availability. There is no public online status tracker for this filing. Use EP Customer Account Services for status questions.
What Form 5308 Does
Form 5308, Request for Change in Plan/Trust Year, is how you ask the IRS to approve a change in a plan year or a related trust year. You use it when a plan subject to the minimum funding standards, or a plan trust, needs an off‑cycle start or end date, often after a merger, fiscal year realignment, or a cleanup of past errors. The form is short, but it is a formal request that can be approved or denied, and it carries a user fee.
When you do not need to file
The official instructions carve out several exceptions. Profit‑sharing plans, stock bonus plans, certain insurance contract plans, governmental plans, and nonelecting church plans do not have to file Form 5308 to change the plan year. The trust still may need approval if its year is changing, and all automatic approval conditions must be met. Always confirm you qualify before skipping the form.
Why firms trip up on this filing
If you run a CPA or EA firm, you already know the pattern. The challenge is rarely finding a reason to change the plan year, it is executing cleanly without surprises. Common pain points include missing the short‑year deadline, thin documentation for the business reason, unclear workpapers, and slow coordination with the actuary. Those are delivery problems, not sales problems, and they are solvable with a disciplined workflow.
A change in plan year or funding method takes effect only if approved by the Secretary. Treat it as a controlled process with artifacts, not a casual form.
Who typically files Form 5308
Plans subject to IRC §412 minimum funding standards, for example single‑employer defined benefit, money purchase, and target benefit plans, generally must seek approval unless automatic approval applies. Any employees’ trust that is part of a qualified plan needs approval to change its trust year. This is why you will often file two boxes on the form, one for plan year and one for trust year.
Real‑world triggers
- Mergers or acquisitions that force one calendar across entities
- Sponsor changes in taxable year that make a short plan year logical
- ESOP adoption or termination with timing adjustments
- Correcting an incorrect plan year set long ago
When you describe the reason, stick to the business reality and avoid language that suggests you are chasing a funding or PBGC premium outcome. IRS guidance cautions that using a plan year change to delay the effect of a statute will not qualify for automatic approval and is scrutinized on review.

How to decide, Do you qualify for automatic approval or do you need IRS consent?
Start here, because it drives your timeline and workload.
- Automatic approval, You can avoid filing if you meet every condition in Rev. Proc. 87‑27, including that no plan year is longer than 12 months, no plan year change occurred in the prior four plan years, and the change does not delay the time the plan must conform to any statute or IRS position. If you qualify, do not submit Form 5308. Keep your board resolution and amendment on file.
- IRS consent, If any condition is not met, or your plan type requires consent, file Form 5308 with the user fee and full support.
Quick rule of thumb, if you are not sure you meet every automatic‑approval condition, treat it as a consent filing and prepare the package.
Filing calendar and destination
- Deadline, File by the last day of the short plan year, for example if your short year ends December 31, 2025, your package must arrive by December 31, 2025.
- Where to send, Use the EP Letter Rulings addresses.
- USPS, Internal Revenue Service, Attn, EP Letter Rulings, TE/GE Stop 31A Team 105, P.O. Box 12192, Covington, KY 41012‑0192.
- Private delivery, Internal Revenue Service, Attn, EP Letter Rulings, 7940 Kentucky Drive, TE/GE Stop 31A Team 105, Florence, KY 41042.
- Copies, The 11‑2019 form says “File in Duplicate.” More recent EP procedures generally require one copy unless specific conditions apply, but for Form 5308 follow the form’s instruction unless an IRS specialist directs otherwise.
User fee and payment
- User fee, IRS materials list a user fee of $1,000 for a change in plan year letter ruling. Verify the fee against the current annual EP revenue procedure, since fees can change.
- How to pay, EP user fees are governed by the annual revenue procedure. Determination letter user fees often run through Pay.gov, while letter rulings may be paid per instructions in the current revenue procedure. Coordinate with your EP specialist if you want to use Pay.gov or must include a check.
What to include in your package
The form itself is brief. The quality of your attachments is what speeds approval.
- Core details, employer and plan identifiers, plan number, current and proposed year ends, short year dates, contact info.
- Statement of reasons, clear business explanation for the change, not just a result you hope to achieve. IRS expects a bona fide operational need.
- Board resolution and plan amendment, adopted on or before the end of the short period.
- Actuarial materials for DB plans, valuation report references, minimum required contribution impact, deduction discussion if applicable, and confirmation you will follow the funding method and deduction rules.
- Prior year history, note any plan year changes within the last four plan years.
- Trust year details, if the trust year changes, include trust documents and exempt status confirmations.
Documentation table you can mirror
| Item | Include | Why it matters |
| Identification | Plan name and number, EIN, contact | Ensures EP can locate and log your case |
| Dates | Current and proposed year ends, short year dates | Drives deadlines and testing periods |
| Authority | Board resolution, plan amendment | Proves actions were adopted on time |
| Business reason | Merger alignment, fiscal year change | Shows bona fide need, not outcome shopping |
| Actuarial impact | Short year funding, MRC, deductions | Confirms compliance for DB plans |
| History | Prior changes in last 4 years | Automatic approval condition check |
| Trust items | Trust agreement, exemption status | Required if the trust year changes |
Step‑by‑step, from decision to submission
- Confirm whether automatic approval applies. If not, plan for a consent filing.
- Draft the statement of reasons and assemble supporting facts.
- Coordinate early with the actuary to map valuation date, MRC, testing, and notices for a short year.
- Adopt the plan amendment and board resolution on or before the end of the short period.
- Complete Form 5308, add the user fee, and prepare duplicate copies.
- Ship to the correct EP address with tracking and keep proof of delivery.
Pro tip, put “Form 5308,” plan name, EIN, and filing date on each attachment so nothing gets separated in processing.
Processing times and status checks
There is no public online tracker specific to Form 5308. Expect mailed acknowledgment and follow‑ups by letter. Processing can run from a few weeks to several months depending on complexity and workload. For status checks, call Employee Plans Customer Account Services at 877‑829‑5500. If you filed with a cover letter, keep the correspondence number handy.
If you do not receive an acknowledgment within 60 to 90 days, send a written inquiry to the same EP address you used for filing and retain delivery proof. If you use a private delivery service, make sure you used the Florence, KY street address, not the P.O. box.
Practitioners with proper authorization can also use the IRS Practitioner Priority Service for account‑related questions, though EP Customer Account Services is the primary line for retirement plan submissions. PPS operates at 866‑860‑4259, weekdays, with published hours.
How a plan year change affects funding, testing, and operations
Changing the plan year is not just a form, it shifts your entire compliance calendar.
- Funding and deductions, DB plans must align MRC and deduction timing with the short period, and the form asks you to explain deduction effects if applicable.
- Valuation date and audits, your actuary and auditor may need to adjust procedures and system timing to the new year.
- Participant notices and PBGC, deadlines shift with the plan year. Avoid aiming at PBGC premium timing, since IRS says automatic approval is not available if the change delays the effect of a statute like PBGC premium increases.
A simple short‑year timeline you can adapt
- Week 1 to 2, confirm automatic approval versus consent and draft the reason statement.
- Week 3 to 6, actuary models funding and testing for the short year, you update the amendment and board resolution.
- Week 7 to 8, finalize Form 5308, attach support, cut the user fee, and ship with tracking.
- Weeks 10 to 16, watch for acknowledgment by mail, respond quickly to any IRS information requests.
- Close of short year, ensure contributions, notices, and filings reflect the new year and short period where required.
Sample “statement of reasons” outline
Use this structure and keep it factual.
- Business context, “On October 1, 2025, Sponsor acquired ABC Inc. and consolidated finance calendars to December 31.”
- Plan administration, “Payroll, audit, and actuarial processes are now aligned to the new fiscal cycle.”
- Prior changes, “No plan year change occurred in the prior four plan years.”
- Short period, “The plan will have a short year from July 1, 2025 to December 31, 2025.”
- Funding and testing, “The actuary has adjusted valuation and MRC for the short period and will complete testing on the short‑year basis.”
- Trust year, “The trust year will change to match the plan year, trust remains exempt and has no UBTI for the short period.”
- Contacts, name, title, phone, and email for the preparer.
Common pitfalls and how to avoid them
- Thin documentation, send a clear business reason and the right attachments.
- Late adoption, adopt the plan amendment and board resolution by the short‑period end.
- Wrong address, use Covington for USPS and Florence for private delivery.
- Chasing outcomes, do not frame the change as a way to delay statutory impacts such as PBGC premiums.
- Fee mistakes, confirm the current user fee before you send payment.
How disciplined delivery shortens review time
Clean workpapers, consistent file names, and clear version control make reviews faster, especially when IRS asks follow‑up questions. If you run a growing firm, keep a standard 5308 packet template with labeled exhibits. That way, anyone on your team can assemble a submission that passes an internal checklist before it goes out.
We have seen the fastest turnarounds when the “reason” statement is one page, the amendment and resolution are dated, the actuarial memo is concise, and every attachment is labeled with the plan name, EIN, and “Form 5308.”
FAQs
Do I always need IRS approval to change a plan year?
No. Some plan changes qualify for automatic approval under Rev. Proc. 87‑27 if every condition is met, and some plan types, like profit‑sharing plans, do not need to file Form 5308 to change the plan year. If in doubt, review the Form 5308 instructions and the revenue procedure before you assume you are exempt.
Where do I mail Form 5308?
Use EP Letter Rulings in Kentucky. USPS mail goes to the Covington P.O. Box. Private delivery services must use the Florence street address. The IRS reconfirmed these addresses, and the form’s instructions list both.
Is there an online tracker for Form 5308?
No public tracker is available. Expect mailed acknowledgment and letters for information requests. For status, call EP Customer Account Services at 877‑829‑5500 and keep your plan name, EIN, and filing date ready.
What is the current user fee?
IRS materials list a fee of $1,000 for a change in plan year letter ruling. Fees can change with the annual EP revenue procedure, so confirm the current schedule when you file.
What is a 5329 form used for?
Form 5329 reports additional taxes on early distributions, excess contributions, and missed RMDs, and it claims exceptions where applicable. You file it with your return or standalone when required. Always use the current instructions for calculation rules.
What is the purpose of Form 8308?
Form 8308 is used to report certain sales or exchanges of partnership interests with unrealized receivables or inventory items under IRC §751, so the IRS can verify proper tax treatment. Review the latest instructions before filing.
What is the IRS form to cancel all debt?
There is no single form that cancels debt. Creditors issue Form 1099‑C when they discharge debt, and taxpayers may need Form 982 to claim an exclusion. Report any cancellation of debt income correctly on your return.
Who needs to fill the W‑8 form?
Non‑U.S. individuals provide Form W‑8BEN, and non‑U.S. entities provide Form W‑8BEN‑E, to certify foreign status and claim treaty benefits with payers. U.S. persons do not use W‑8 forms.
