The Michigan Department of Treasury has been made aware that some "Reminder of Tax Due" letters sent to taxpayers contain an incorrect toll-free (1-800) TTY number, which may connect callers to a potential scam. Taxpayers with questions regarding unpaid individual income taxes are asked to contact the Treasury directly at 517-636-4486. We apologize for any confusion or concern this may have caused.
13. How is a unitary relationship determined?
A unitary relationship exists when a taxpayer has control over the entities and the entities have a flow of value between their various operations. Factors that establish a flow of value include:
- Economic realities
- Functional integration
- Centralized management
- Economies of scale
- Substantial mutual interdependence
These factors are not exhaustive or exclusive and the ability to elect combined apportionment will depend on the totality of the circumstances.
