What this schedule is for
Schedule SB is the actuarial-information schedule for certain single-employer defined benefit plans. It relies on plan actuarial data and must be coordinated with the actuary.
Preparation checklist
- Obtain actuarial valuation information for the applicable plan year.
- Coordinate funding, target and contribution information with the plan actuary.
- Confirm required attachments and certifications.
- Review current instructions and PBGC/IRS guidance when relevant.
How it fits into the Form 5500 workflow
Schedule requirements are driven by the plan's facts, funding arrangements and filing type. A good preparation process starts with the main Form 5500 or Form 5500-SF determination, then adds only the schedules required by the current instructions.
Do not rely on the schedule name alone. Review the current Form 5500 instructions and the schedule-specific instructions for the filing year before deciding whether the schedule is required.
