Relating to: zero-based biennial budget requests by executive branch agencies. (FE)

SB 555 requires Wisconsin's executive branch agencies to submit biennial budget requests using "zero-based budgeting" for 20% of agencies each fiscal biennium, starting in 2027-29. This means agencies must justify every budget line item based on current needs and goals, rather than relying on previous funding levels. The bill also mandates that agencies analyze whether past appropriations met their intended goals and explain any shortfalls, with these reports posted online. It directly affects all state executive agencies submitting budget requests, shifting how they justify spending. The changes take effect for the 2027-29 budget cycle.
