Michigan Compiled Laws, Chapter 18. Department of Management and Budget § 18.1350b

Sec. 350b. (1) Effective with the 1979-80 state fiscal year, and for each state fiscal year thereafter, the legislature shall not impose taxes of any kind which would result in total state revenues exceeding the revenue limit established in subsection (2).

(2) The revenue limit shall be equal to the product of the ratio of total state revenues in the 1978-79 state fiscal year divided by the personal income of Michigan in calendar year 1977 computed by rounding the quotient to 4 decimal places, multiplied by the personal income of Michigan in either the prior calendar year or the average of personal income of Michigan in the previous 3 calendar years, whichever is greater.

(3) The department shall submit to the legislature, the fiscal agencies, and the auditor general not later than June 30, 1989 a report which shall calculate in detail the base revenue limit as established in subsection (2). This report shall become effective 90 days after submission to the legislature unless disapproved by a concurrent resolution approved by a majority of the members elected and serving in each house by a record roll call vote. If this report takes effect, the calculation of the base revenue limit contained in the report shall be used for the purposes of subsection (2).
