Here are the key deadlines for 2026, outlining the annual notice requirements that employer-sponsored plans need to meet. Certain compliance deadlines are linked to the group health plan’s plan year. The chart that follows highlights deadlines specific to calendar-year plans; for plans operating on a non-calendar year, be sure to adjust these timelines according to your unique plan year schedule.   ## **Determining the Plan Year** The “plan year” refers to the specific 12-month period your benefits plan uses for recordkeeping. This could match the calendar year, a fiscal year, or the policy year determined by your insurer. While many employers align their group health plans with the calendar year (January 1 to December 31), others opt for a custom schedule that better fits their organization’s fiscal cycle or the terms of their insurance policy.   ## **Compliance Deadlines** Download the [2026 Health Plan Compliance Deadline Guide ](https://blog.nisbenefits.com/hubfs/blog-supporting-docs/bulletin-2026-health-plan-compliance-deadlines.pdf)to help you note key dates including: - Form W-2 - Sections 6055/6056 reporting - Medicare Part D notices - Prescription drug reporting - PCORI fee - Form 5500 - Medical loss ratio rebates - Summary of benefits and coverage (SBC) - Annual Notices - And more   For more information about reporting or disclosure requirements, contact your [NIS Benefits Consultant](https://www.nisbenefits.com/consulting/consulting-team/).
