• Conduct 501(c)(3)/501(c)(4) analysis to confirm that the C4 entity is appropriately paying its full share for services provided by the C3 entity.


• Review and document cost allocations and inter-entity arrangements to help ensure appropriate separation between the C3 and C4 organizations.


• Review the organization's existing compliance calendar and filing schedule for completeness and accuracy.


• Identify outstanding or overdue compliance requirements and assist with bringing filings and other obligations up to date.


• Assess the current approach to managing compliance responsibilities across multiple departments and identify gaps in ownership, visibility, and oversight.


• Recommend and help implement an improved centralized compliance tracking and oversight process to manage ongoing filing and regulatory requirements.


• Potentially support preparation and review of the 2026 C3 and C4 Form 990 filings.


• Develop a fully reconciled, well-documented Form 990 work file and supporting process that can be replicated efficiently in future years.


• Partner with internal finance, accounting, legal, and other stakeholders as well as external tax advisors as required.

• Experience responding to and resolving IRS notices and compliance matters.


• Understanding of the tax and compliance considerations associated with relationships between C3 and C4 entities.
