California’s enacted 2025-26 state budget includes nearly $175 billion in federal funds, which works out to 35.2% of total state spending.1California Budget & Policy Center. Federal Funds Drive One-Third of California’s State Budget That is the figure for money routed through Sacramento. The full answer to how much federal money California gets is considerably larger, because Social Security checks, Medicare reimbursements, defense contracts, veterans’ benefits, and federal employee paychecks reach the state without ever touching the state treasury.
Roughly one dollar in three of what the state spends comes from Washington, and that share has held fairly steady across recent budget cycles outside the pandemic spike. California’s federal allocation alone is larger than the entire budget of most states.
Where the $175 Billion Goes
Most federal dollars in the state budget arrive earmarked. The money is restricted to specific programs and cannot be redirected to plug gaps elsewhere, which is why so much of the total tracks a handful of large programs.
Health Care
Medi-Cal, California’s Medicaid program, is the single largest driver. It covers roughly 15 million low-income residents and draws from federal matching funds authorized under Title XIX of the Social Security Act.2Social Security Administration. Social Security Act Title XIX – Grants to States for Medical Assistance Programs California’s base federal match sits at the 50% statutory floor for most traditional enrollees, but adults who gained coverage through the Affordable Care Act’s Medicaid expansion are matched at 90%.3Medicaid and CHIP Payment and Access Commission. Matching Rates With more than one in three Californians enrolled, any shift in federal Medicaid policy moves the state budget almost immediately.
Food Assistance
CalFresh, California’s version of SNAP, is the second-largest conduit. In 2024-25, about 5.5 million Californians received more than $12.5 billion in CalFresh benefits, averaging roughly $192 per person per month.4Legislative Analyst’s Office. The 2026-27 Budget: Food Assistance Programs The federal government pays 100% of benefit costs and splits administrative expenses with the state 50-50.5eCFR. 7 CFR 277.4 – Funding
Education
Title I of the Elementary and Secondary Education Act sends federal money to school districts with high concentrations of students from low-income families.6U.S. Department of Education. Title I The Individuals with Disabilities Education Act separately funds special education services. California’s student population pulls one of the highest Title I allocations in the country in absolute terms, though per-pupil amounts often lag smaller states because the formula does not scale proportionally with population.
Infrastructure
The Bipartisan Infrastructure Law, signed in 2021, directed tens of billions in new federal money toward California over five years. The largest piece, roughly $29.5 billion, goes to highway and bridge improvements through formula funding. Public transportation gets about $10.3 billion and airports around $1.5 billion. Smaller allocations cover electric vehicle charging ($384 million), highway safety ($179 million), and transportation emissions reduction ($555 million).7U.S. Department of Transportation. The Bipartisan Infrastructure Law Will Deliver for California Most of this flows through grants to state transportation agencies, local transit authorities, or utilities rather than into the general state budget.
Federal Money That Skips the State Budget
A much larger stream of federal spending in California never passes through Sacramento. Defense spending alone totaled $60.8 billion in California during fiscal year 2023, covering military base operations, personnel, and contracts with private defense firms.8U.S. Department of Defense. DOD Releases Report on Defense Spending by State in Fiscal Year 2023 California hosts numerous major military installations, and its aerospace and technology sectors win a disproportionate share of federal procurement.
Social Security payments to retired and disabled Californians add another enormous sum delivered directly to individuals. Veterans’ benefits, Medicare payments to hospitals and doctors, and federal research grants to universities like the UC system all fall into this category as well. A precise combined figure is hard to pin down because different agencies report on different timelines, but the total federal economic footprint in California easily runs into several hundred billion dollars a year once direct payments, defense contracts, and federal wages are added to the state-budget share.
What California Gets Back Per Tax Dollar
California has long been a donor state. The Rockefeller Institute of Government estimated that in federal fiscal year 2022, California received approximately $0.90 for every dollar its taxpayers sent to Washington.9Rockefeller Institute of Government. Giving or Getting? Balance of Payments 2024 That ten-cent gap adds up to tens of billions annually.
The reason is structural. California has an outsized concentration of high-income earners and profitable corporations that generate enormous federal income and payroll tax revenue. The state’s tax base exceeds what federal spending formulas return. Poorer states with lower tax contributions but high per-capita needs for programs like Medicaid and Social Security disability tend to receive more than they pay in.
The ratio moves with the economy and with tax policy. Pandemic relief temporarily pushed California closer to break-even. The 2025 reconciliation law extended Tax Cuts and Jobs Act provisions, including the $10,000 cap on the state and local tax deduction, which continues to limit a tax break that disproportionately benefits Californians who pay high state income and property taxes.
What Changes in 2026
The federal spending and tax law signed on July 4, 2025, is the most significant shift in California’s federal funding picture in years. The reconciliation package, H.R. 1, extended the 2017 tax cuts while making deep Medicaid changes that hit California hard. State analysts estimate California could lose roughly $30 billion in federal Medi-Cal funding annually, and up to 3.4 million residents could lose their health coverage as a result.10California State Assembly Health Committee. Impact of Federal Funding Cuts to Medicaid (Medi-Cal) on California
Several provisions are already live or taking effect soon:
- Provider tax restrictions in effect since July 2025 ban certain provider taxes and require Medicaid plans to be taxed at the same rate as non-Medicaid entities, reducing revenue from California’s managed care organization tax and Hospital Quality Assurance Fee.
- State-directed supplemental payments to providers are now capped at 100% of Medicare rates, lower than what California had been paying.
- Starting October 2026, the 90% federal match for emergency Medicaid services for certain immigrants who would otherwise qualify under the ACA expansion ends, shifting costs to the state.
- Also starting October 2026, Medi-Cal and CHIP eligibility narrows to U.S. citizens, nationals, and a limited set of immigrant categories including green card holders and certain refugees.
For a state where Medi-Cal covers more than a third of the population, these are not abstract line items. Hospitals that serve high numbers of Medi-Cal patients face real financial pressure when supplemental payments shrink and the uninsured population grows, and the legislature will have to decide whether to backfill lost federal dollars with state funds or let coverage gaps widen.
