(a) Returns under section 4980B.
(1) Due date for filing of return by employers or other persons responsible for benefits under a group health plan.

An extension to file the person's income tax return does not extend the date for filing Form 8928.
(2) Due date for filing of return by multiemployer plans. If the person liable for the excise tax is a multiemployer plan, the return required by § 54.6011–2 must be filed on or before the last day of the seventh month following the end of the plan's plan year.

An extension to file the employer's income tax return does not extend the date for filing Form 8928.
