    Other Wyoming Transparency Resources

    Wyoming operates under a two-year budgeting process often called a biennial budget. As part of this process the Governor proposes to the Legislature a budget that covers the next two fiscal years, which run from July 1 to June 30. The two-year budget is debated and passed in even years (i.e. 2018, 2020).
