U.S. public elementary and secondary schools take in roughly $927 billion a year, and the money comes from three levels of government in very uneven shares. State governments supply about 46 percent, local governments (mainly through property taxes) cover about 44 percent, and the federal government contributes roughly 9 to 10 percent in a typical year.1National Center for Education Statistics. Public School Revenue Sources That works out to about $18,614 per student on average, though what any given district actually spends varies enormously depending on where a child lives.2National Center for Education Statistics. Public School Expenditures So when people ask how much tax money goes to education, the honest answer starts with those three buckets and then follows the dollars into classrooms.
The Federal Share
Federal funding for K-12 has historically stayed between 8 and 10 percent of total school revenue.1National Center for Education Statistics. Public School Revenue Sources It spiked briefly during pandemic relief spending and has since settled back into that range. For fiscal year 2026, the Department of Education’s total discretionary budget sits at roughly $79 billion, which covers K-12 grants, higher education programs, and student financial aid combined.
Those dollars come from the same individual and corporate income taxes that pay for every other federal program. They reach schools through targeted grants rather than general operating support. The biggest is Title I under the Every Student Succeeds Act, which sends money to schools with high concentrations of students from low-income families.3Congress.gov. Public Law 114-95 – Every Student Succeeds Act The Individuals with Disabilities Education Act is the second major pipeline, funding services for children with disabilities.4Office of the Law Revision Counsel. 20 USC Ch 33 – Education of Individuals With Disabilities A smaller program called Impact Aid compensates districts that lose property tax revenue because of federal land, military bases, or tribal territory inside their boundaries, since that property cannot be taxed locally.5Office of the Law Revision Counsel. 20 USC Ch 70, Subchapter VII – Impact Aid
The pattern across all these programs is the same. Federal money targets specific student populations or specific gaps. It does not pay the day-to-day cost of running a classroom.
The State Share
State governments are the single largest source of school funding at roughly 46 percent of total revenue.1National Center for Education Statistics. Public School Revenue Sources The money comes primarily from state income taxes and sales taxes, which flow into general funds. Legislators then decide how much to appropriate for schools each budget cycle.
Most states distribute that money using foundation formulas. The formula starts with a base per-student amount and layers on extra weighted funding for categories like special education, English language learners, and low-income students. The idea is to level the difference between wealthy and poorer districts, though the results vary widely from state to state. Every state constitution contains some form of mandate requiring the state to provide public education, which is what gives legislatures both the authority and the obligation to fund schools.
What About Lottery Money?
About two dozen states earmark a portion of lottery proceeds for education. In practice, lottery revenue usually amounts to a small fraction of the state’s total education budget. It also tends to be partly absorbed by a substitution effect: when lottery dollars come in, legislators redirect general fund money that would have gone to schools somewhere else. The net boost is smaller than the marketing suggests.
The Local Share and Property Taxes
Local governments provide about 44 percent of public school revenue, and nearly all of that comes from property taxes.1National Center for Education Statistics. Public School Revenue Sources The bill you pay for schools is based on your home’s assessed value multiplied by a local millage rate. One mill equals one dollar of tax for every $1,000 of assessed value. A home assessed at $250,000 in a district with a 20-mill school levy owes $5,000 in school taxes.
This arrangement gives communities direct control over what they spend on their own schools. It also produces the sharpest inequities in American education. Areas with expensive homes and commercial real estate generate far more per student than lower-income areas, even when poorer communities tax themselves at higher rates. State foundation formulas try to close the gap, but in nearly half of all states, students from low-income families still receive less combined state and local funding than their wealthier peers. Per-pupil spending runs from around $10,000 in the lowest-funded states to over $30,000 in the highest.
Bond debt for school construction sits outside this operating math. When a district builds or renovates, it issues general obligation bonds that voters approve, and repayment shows up as a separate line item on your property tax bill until the bonds are paid off.
Where the Money Goes Once Schools Have It
People are the overwhelming expense. Salaries and benefits for teachers, aides, administrators, counselors, nurses, and support staff consume roughly 80 to 85 percent of a typical district’s operating budget. That is more than double what most private-sector organizations spend on personnel, and it reflects the labor-intensive nature of education. A second-grade classroom cannot be automated.
The remaining 15 to 20 percent covers building maintenance, utilities, textbooks, classroom technology, transportation, and food service. Instructional costs dominate within the personnel share, led by teacher pay and classroom aide wages, followed by health insurance and pension contributions that have grown considerably over the past two decades. Administrative costs, meaning principals, central office staff, and district operations, are a common target of criticism but generally represent a modest slice of total spending compared with direct instruction.
Higher Education Runs on a Different Model
Public colleges and universities are funded very differently from K-12. State governments provide direct appropriations, totaling roughly $129 billion per year across all states. Public institutions also collect tuition and pull in revenue from research grants, private donations, and operations like housing and athletics. Local property taxes play almost no role.
The federal government’s main contribution to higher education flows through student financial aid rather than institutional support. The Pell Grant is the largest program, providing up to $7,395 per year to undergraduate students with financial need for the 2025-2026 and 2026-2027 award years.6Federal Student Aid. 2025-2026 Federal Pell Grant Maximum and Minimum Award Amounts Federal agencies also distribute billions each year in research grants to university labs. The result is a funding mix that is more diversified than K-12 but also more dependent on tuition, which pushes cost directly onto students and families.
When Tax Dollars Follow the Student Instead of the District
The traditional picture, where your school taxes fund the public district where you live, no longer covers the whole map. Charter schools are publicly funded but independently operated, and they draw per-pupil allocations from the same state and local revenue streams as traditional districts. When a student transfers to a charter school, the funding moves with the student.
A growing number of states have also created education savings accounts and voucher programs that allow families to use public funds for private school tuition, homeschooling costs, tutoring, and educational materials. Some are financed through direct state appropriations. Others use tax credits, letting individuals or businesses receive credits for donating to scholarship-granting organizations. The practical effect either way is that tax dollars intended for public schools are redirected based on parental choice. Whether that helps students or drains resources from public districts depends on the specific program and on who you ask.
