How to use this checklist
A defensible MSO management fee is not the result of a single document; it is the result of a coordinated documentation file maintained across the agreement, the study, the cost base, the invoicing system, and the annual refresh cycle. This checklist is the file index. It is a diligence tool for CPA firms and tax counsel coordinating with GTC on MSO compliance, not a tax opinion.
1. Written Management Services Agreement
- ☐ Executed MSA dated before services begin, signed by both entities.
- ☐ Defined scope, term, renewal, termination, and dispute-resolution provisions.
