Maintenance and Operations Overrides are used to provide additional funding to support people and programs. School districts may ask for an increase of up to 15 percent of their revenue control limit for a term of seven years. Many districts will ask voters to approve a renewal in year 4 or 5 of an override to maintain a consistent level of funding. If not renewed, the amount decreases by 1/3 in the sixth year, 2/3 in the seventh year, and is fully eliminated in year eight. The Higley Unified School District has had an override in place since 2019, however, it expires in 2025.

HUSD spends 70% of its budget in the classroom. In Higley, only about 10 percent of the budget is spent in the Administration category, which includes not just administrator salaries but also payroll, purchasing, warehousing, printing, human resource activities, administrative technology services; and other costs related to these services and the governing board. HUSD takes a conservative, student-first approach to making the most of every cent, prioritizing impact in the classroom. According to the Auditor General, HUSD spending is "Low" compared with similar districts and districts across the state, though academic standards and test scores still exceed state and peer averages. For more comprehensive information on district spending, see the Auditor General Classroom Spending Report.

HUSD has consistently operated within all approved budget limits each fiscal year and has delivered previous bond projects on time and within budget.  The district has earned over several awards for fiscal responsibility including the 2024 Government Finance Officers Association (GFOA) Certificate of Achievement for Excellence in Financial Reporting as well as the Association of School Business Officials International (ASBO) Certificate of Excellence in Financial Reporting.

The District is required by law to present a detailed expenditure report to the Governing Board in September or October of every year regarding any voter approved funding including Overrides. The community and public are welcome to review these presentations online or join the Board meetings in-person.
