Police departments in the United States are funded primarily by local taxes, with roughly 87% of police spending drawn from city and county budgets and the rest filled in by state contributions, federal grants, forfeiture proceeds, and various fees and fines.1Urban Institute. Criminal Justice Expenditures: Police, Corrections, and Courts In 2021, state and local governments together spent about $135 billion on policing, which works out to roughly 6% of all local government spending and around 13% of the average city budget. That means the practical answer to how police departments are funded starts with the property taxes, sales taxes, and business taxes that fill a municipality’s general fund, and it ends with a web of legal restrictions that determine how little of that money is actually free to move.
Local Taxes Do Most of the Work
The dominant funding source for almost every police department is the local government’s general fund. Property taxes are the single largest contributor for most municipalities, followed by local sales taxes and taxes on businesses. Those revenues flow into one pot, and the city council or county board decides each year how much of the pot goes to policing versus schools, roads, parks, and everything else the jurisdiction pays for.
Because the general fund is tied to the local economy, a department’s resources track the health of its tax base. A city with strong commercial property values and steady retail activity can support a larger, better-equipped force than a similarly sized city in a struggling area. When property values fall or sales tax receipts drop in a downturn, policing feels the pressure alongside every other department. Grants can soften the impact, but they rarely replace a sustained loss of local revenue.
Federal Grants Fill Specific Gaps
State governments contribute a comparatively small share of total police funding, mostly for specialized functions such as highway patrols and forensic laboratories. The more meaningful outside money comes from the federal government through two Department of Justice programs.
Byrne JAG
The Edward Byrne Memorial Justice Assistance Grant program sends federal money to state and local governments for defined criminal justice purposes, including drug enforcement, technology, equipment, and training.2Office of the Law Revision Counsel. 34 USC Subtitle I, Chapter 101, Subchapter V, Part A – Edward Byrne Memorial Justice Assistance Grant Program A non-supplanting rule requires that the federal dollars add to what the local government would have spent anyway, not replace it. Agencies that accept Byrne JAG must certify compliance, and the Attorney General can cut future allocations to agencies that don’t follow the rules.
COPS Hiring Program
The Community Oriented Policing Services office has distributed more than $20 billion since 1994, funding the hiring of about 138,000 officers across more than 13,000 agencies.3United States Department of Justice. Justice Department Awards Over $600M to Hire Law Enforcement Officers, Keep Schools Safe, and Improve Law Enforcement Mental Health and Wellness Services Unlike Byrne JAG, the COPS Hiring Program requires a local cash match of at least 25% of the total award, and agencies must retain every federally funded position for at least 12 months after the 36-month grant period ends, using state or local money.4COPS Office, U.S. Department of Justice. FY25 COPS Hiring Program Application Resource Guide A COPS grant is therefore a multi-year commitment: an agency that can’t sustain the positions after the federal money runs out faces real consequences.
Fees, Fines, and Asset Forfeiture
Departments also generate revenue through traffic tickets, fees, and civil fines, but that money generally flows into the local general fund rather than back to the department. Asset forfeiture is the exception worth understanding.
Federal and state laws allow law enforcement to seize property and cash tied to criminal activity. At the federal level, the Comprehensive Crime Control Act of 1984 created the Department of Justice Assets Forfeiture Fund to receive these proceeds, and the Attorney General can use the fund for forfeiture-related expenses, including equipment, investigations, and training.5U.S. Department of Justice. Assets Forfeiture Fund Nearly nine out of ten jurisdictions direct forfeiture proceeds to law enforcement agencies or law enforcement purposes.
When a local agency assists in a federal forfeiture case, it can receive a share of the proceeds through the DOJ’s equitable sharing program. The federal government keeps a minimum of 20%, and the local share depends on the agency’s contribution to the investigation, measured by work hours and the significance of its role.6U.S. Department of Justice. Guide to Equitable Sharing for State, Local, and Tribal Law Enforcement Agencies Shared funds have to supplement the agency’s regular budget, not replace it. A local government that tries to cut a department’s appropriation and backfill it with forfeiture money risks losing access to equitable sharing entirely. Agencies also cannot budget around anticipated receipts; they can only plan spending for money already received. Permissible uses include equipment, training, facility costs, and joint operations. The money cannot fund new facility construction (under DOJ sharing), personal expenses, political activities, or anything that creates the appearance of personal benefit.
Where the Money Actually Goes
About 96% of police spending goes to operational costs, mostly salaries and benefits. The remaining 4% or so covers capital purchases like vehicles, facilities, and major equipment.1Urban Institute. Criminal Justice Expenditures: Police, Corrections, and Courts That split explains a lot: any real conversation about police funding is a conversation about staffing, because there is not much else to cut.
Salaries, overtime, health insurance, and pension contributions for both sworn officers and civilian staff drive the bulk of any police budget. This number does not swing much year over year. It’s driven by workforce size, labor contract terms, and rising benefit costs. Pension contributions alone can consume a significant and growing share, especially where the pension system is underfunded.
Overtime is the fastest-growing pressure point. When a department can’t fill its authorized positions, mandatory overtime keeps minimum patrol staffing intact, and departments with significant vacancies have seen overtime climb to 6% or more of the total budget. Compensatory hours banked rather than paid out grow more expensive when officers later receive raises or promotions before cashing them in. Overtime is where staffing shortages show up on the balance sheet.
Day-to-day operations cover fleet fuel, utilities, supplies, and administrative costs. Capital spending funds patrol vehicles, communication systems, facility work, and major technology deployments. Because capital is such a small slice, it’s often the first target when budgets tighten, which produces aging fleets and deferred maintenance that cost more to fix later. Mandated training, professional development, body-worn cameras, in-car video, and data platforms are often the categories federal grants target, which is how many smaller departments afford tools they couldn’t buy from the general fund.7United States Department of Justice.

What Locks the Money In
Elected officials appear to hold broad discretion over police spending. In practice, that discretion is far narrower than it looks, because most of the budget is committed before the council debates it.
Collective Bargaining Agreements
Union contracts set salary scales, overtime rules, health benefits, and retirement payouts for multiple years at a time. When personnel costs consume most of a police budget, a multi-year labor contract pre-commits most of the money. The rigidity runs deeper than base pay. Many contracts include terminal leave (months of paid time off before retirement), compensatory time payouts, longevity bonuses, and other benefits that are hard to remove. Even when a contract expires, past practice clauses can require the municipality to keep paying established benefits until the union agrees to a change. The realistic path to lower costs is negotiating reduced benefits for officers not yet hired, so savings take years or decades to materialize.
Pension and Retiree Health Obligations
The personnel costs visible in any single year’s budget are only part of the story. Police pension obligations extend decades into the future, and many systems carry large unfunded liabilities. Across all state and local public pension plans, unfunded liabilities totaled an estimated $1.37 trillion as of 2024, with the average funded ratio around 80%.8Equable Institute. Pension Plan Funded Ratio Rankings 2024 Some police pension systems are fully funded or close to it. Others are in crisis. The Chicago Police pension fund had a funded ratio of just 26.5%, and the Dallas Police and Fire system sat at 36.8%. A deeply underfunded system pressures the city to increase annual contributions by tens of millions of dollars, crowding out operational spending. Retiree healthcare obligations add another layer, often funded on a pay-as-you-go basis and representing billions in liabilities.
Misconduct Settlements
When an officer violates someone’s constitutional rights, the injured person can sue the officer and the employing municipality under federal civil rights law.9Office of the Law Revision Counsel. 42 USC 1983 – Civil Action for Deprivation of Rights Over a recent decade, just the 25 largest police and sheriff’s departments made nearly 40,000 payouts for misconduct totaling roughly $3.2 billion. Most municipalities pay claims from the general fund. Some issue bonds to cover large settlements, spreading the cost across years but adding interest. Smaller jurisdictions rely on liability insurance or shared risk pools, and insurers have responded to rising claims with steep premium increases. In extreme cases, communities have raised property taxes to the maximum permitted by law to cover a single settlement. Because settlements come from general funds rather than the police budget line, they rarely create direct financial pressure on the department whose conduct produced the claim.
Legal Limits on Moving the Money
Not every funding decision is left to local discretion. Several legal layers shape what municipalities can and must spend on policing.
Grant Earmarks
Federal grants come with earmarking requirements that bar their use for general operating expenses. Byrne JAG funds are limited to the criminal justice purposes defined in the statute, including drug enforcement, technology improvements, equipment, and training.2Office of the Law Revision Counsel. 34 USC Subtitle I, Chapter 101, Subchapter V, Part A – Edward Byrne Memorial Justice Assistance Grant Program Local governments can’t redirect those dollars to routine salaries or maintenance, and the non-supplanting rule requires the money to add to total spending rather than substitute for it.
Consent Decrees
When the Attorney General finds reasonable cause to believe an agency has engaged in a pattern of conduct that violates constitutional rights, the DOJ can bring a civil action seeking court-ordered reforms.10Office of the Law Revision Counsel. 34 US Code 12601 – Cause of Action The resulting consent decrees typically require overhauls to training, policies, technology, and accountability systems, all of which cost money. These obligations can last years and lock in spending the local government can’t reduce until the court lifts the decree.
State Preemption Laws
After the policing debates of 2020, several states passed laws restricting a municipality’s ability to cut its own police budget. The approaches vary. Some prohibit reductions above a set percentage per year, with exceptions only for genuine financial hardship. Others impose penalties (loss of annexation authority or mandatory transfer of sales tax revenue to the state) on cities that cut police spending below the prior year’s level. At least one state created a mechanism for citizens or officials to challenge local police budget reductions before a state commission whose decision is final. A city subject to a preemption law may be legally unable to reallocate money from policing to other services even when local voters and elected officials support the change.
Supplemental Funding Through Special Districts
Some communities layer on additional security through business improvement districts and special taxing districts. BIDs are privately directed, publicly authorized organizations that levy compulsory assessments on property owners within a defined area. The revenue funds enhanced services including uniformed foot patrols that coordinate with local police, along with sanitation, lighting, and capital improvements. These arrangements don’t replace police funding. They create a parallel security layer in commercial districts that can afford the extra assessment.
