This form asks the IRS to confirm that a retirement plan—like a pension or profit-sharing plan—is officially qualified under tax law because it is ending. By filing Form 5310, the filer seeks official confirmation of this status before or after the plan shuts down.
A plan sponsor files Form 5310 to request a Determination Letter (DL) regarding the qualified status of their plan upon termination. If the plan sponsor is not certain if they are part of an ASG, they should use Form 5300 instead.
The form collects details about the specific plan and its termination circumstances. Key information includes the type of plan (e.g., defined contribution or benefit) and participant counts shown on line 4e.
An application must be filed no later than the later of 1 year from the effective date of termination or 1 year from the date the action terminating the plan was adopted. It cannot be filed later than 12 months from the date substantial assets were distributed during the termination.
The IRS requires that Form 5310 be completed and submitted through Pay.gov. To submit it, one must register for an account on Pay.gov and enter “5310” in the search box.
First, complete all applicable sections of Form 5310. For a 401(a) plan, ensure Line 1 references the correct EIN used for annual filings. Finally, submit the completed form through Pay.gov after registering an account.
If the application is filed outside of the specified time window, it may not meet the requirement to be deemed filed in connection with plan termination.
If it is a 401(a) plan, use the EIN used when filing Form 5500 series returns; for multiple-employer plans, use the participating employer's EIN. Ensure you do not use the social security number or the trust's EIN.
