FDISD adopts annual budget on the early adoption cycle, meaning that the budgets are adopted prior to setting the tax rate. Adopted Budgets, and Proposed Budgets are listed here. Budgets are, necessarily, the best estimates that the district has during the summers prior to a school year on both revenues and expenses. Revenues include locally collected taxes (currently at the $1.17 rate), state funds (designated bi-annually based on several factors, with enrollments and attendance the largest driving factors), and federal funds (Title programs).

The FDISD Board adopts the budgets listing only locally raised funds and state funding.
