Requires budget unit heads to submit financial estimates by September 1 of each even-numbered year, with budget reports and strategic plans updated every two years instead of annually.

Mandates the Arizona State Retirement System (ASRS) to determine employer contribution rates on a biennial basis and report the contribution rate for two ensuing fiscal years by December 1 of each even-numbered year.

Requires capital improvement plans, building renewal reports, and rental rate determinations to follow the two-year budget cycle, with submissions due in even-numbered years.
