Plan administrators of defined contribution and group health plans have nine months after the end of a plan year to provide participants and beneficiaries with a summary annual report (the SAR). The SAR summarizes the plan's latest annual report/return (Form 5500). For plan years ending December 31, 2010, the deadline for providing the SAR is September 30, 2011. However, if the filing deadline for a plan's Form 5500 is extended, the deadline for providing the SAR is extended by two months.

Administrators of defined benefit plans are not required to provide SARs for plan years beginning after December 31, 2007. Instead, some of the information on the SAR is included in the annual funding notice. The annual funding notice for defined benefit plans must be provided within 120 days following the end of the plan year.
