Ankle Monitor Cost: Do You Have to Pay? (2026)

In most cases, yes: you are expected to pay for your own ankle monitor. Courts in the majority of states order the person being monitored to pay a daily supervision fee directly to a private vendor, typically between $5 and $35 per day. However, constitutional protections, indigency waivers, and a growing wave of state reforms can reduce or eliminate that obligation.

How the Offender-Funded Model Works

Electronic monitoring in the United States expanded dramatically over the past two decades. By the mid-2010s, more than 125,000 people were on ankle monitors on any given day. That number has continued to grow, with ankle monitoring increasingly used as an alternative to pretrial detention and as a condition of probation or parole.

The dominant payment structure is what researchers call the "offender-funded" or "user-funded" model. Rather than the government absorbing the cost of supervision, courts order the monitored person to pay a private vendor directly. The Fines and Fees Justice Center, which surveyed all 50 states and the District of Columbia, found that every state except Hawaii offsets at least a portion of electronic monitoring costs onto people under supervision.

In practice, this means you receive a bill from a for-profit company such as BI Incorporated (owned by GEO Group), Attenti (formerly 3M Electronic Monitoring), Track Group, or Sentinel Offender Services. Some jurisdictions contract directly with these companies; others allow vendors to contract directly with the supervised person, which the Fines and Fees Justice Center flagged as particularly problematic because it eliminates any court oversight of the charges.

The Brennan Center for Justice documented accounts of people selling possessions and donating plasma just to keep up with monitoring bills. A report from Alabama found one woman on house arrest paying $10 per day out of $520 in monthly Social Security benefits, more than half her income, just for the ankle monitor. In Richland County, South Carolina, one man on electronic monitoring paid over $2,500 in nine months to Offender Management Services at a rate of $9.25 per day before surrendering himself to custody because he could no longer afford it.

What Does an Ankle Monitor Actually Cost?

Costs vary by device type, jurisdiction, and vendor contract. The figures below reflect documented ranges from government fee schedules, academic surveys, and reporting by advocacy organizations.

Daily Supervision Fees

The most consistent finding across multiple surveys is a daily fee range of approximately $5 to $35 per day. Passive GPS systems (which download location data periodically) tend toward the lower end. Active continuous GPS monitoring, which transmits location in real time over a cellular connection, typically falls between $10 and $25 per day. Alcohol monitoring devices such as SCRAM bracelets can cost more.

The Brennan Center cited a range of $150 to $900 per month, which translates to roughly $5 to $30 per day. The Fines and Fees Justice Center survey noted fees up to $35 per day in some jurisdictions.

Setup and Installation Fees

Most programs charge a one-time enrollment fee at the start of monitoring. The Fines and Fees Justice Center survey documented installation fees up to $200. The Richland County, South Carolina rate schedule used $179.50 as its setup charge. Some high-volume state contracts negotiate away the installation fee, but that is the exception rather than the rule.

Additional Charges

Depending on the vendor contract, you may also face charges for equipment damage, device replacement, or strap replacements. Some vendors bill separately for the cellular data used to transmit GPS coordinates. Where private vendors contract directly with the supervised person rather than with a court or agency, these add-on charges can be difficult to dispute.

Pretrial vs. Probation vs. Parole

The supervision context matters both for who bears the cost and what legal protections apply.

Pretrial monitoring applies to people who have been charged but not convicted. The constitutional stakes are higher here because the person has not been found guilty of anything. The Fines and Fees Justice Center found that 20 states and the District of Columbia had no explicit statutory authorization for pretrial EM fees, which does not mean fees are not collected but does mean courts in those states have less clear authority to impose them. California's fee prohibition applies at the pretrial stage. Illinois eliminated pretrial EM fees through its Pretrial Fairness Act, which took full effect in September 2023. The Bearden equal-protection concern is sharpest at this stage: an accused person of limited means may effectively be unable to satisfy a release condition not because of any culpable conduct but purely because of poverty.

Probation monitoring is the context where offender-funded fees are most common and most legally established. Courts that impose monitoring as a condition of probation typically order the probationer to pay the monitoring company directly. The 43-state statutory authorization documented by the Fines and Fees Justice Center primarily covers this context. Failure to pay can be treated as a probation violation, which is where Bearden becomes directly relevant.

Parole monitoring involves supervision after a sentence is served. Some states absorb monitoring costs for parolees through their corrections budget, particularly where monitoring is a mandatory condition of release. Others pass costs to the parolee. The specific rules vary considerably by state and, within states, by county or supervising agency.

The Constitutional Floor: Bearden v. Georgia

The Supreme Court's 1983 decision in Bearden v. Georgia, 461 U.S. 660, is the controlling authority on what courts may do when a person on supervision cannot pay a financial obligation.

In Bearden, the Court held that a state cannot automatically revoke probation and imprison someone solely because they failed to pay a fine or restitution if that failure resulted from circumstances beyond their control rather than willful refusal. The Court grounded the rule in the Due Process and Equal Protection Clauses of the Fourteenth Amendment, finding that automatic conversion of an unpaid financial obligation into imprisonment for those who are poor violates fundamental fairness.

The Court established a three-step inquiry. First, did the person willfully refuse to pay, or fail to make bona fide efforts to acquire the resources to pay? Second, if the person genuinely could not pay despite good-faith efforts, are there non-carceral alternatives (extended payment timelines, reduced amounts, or community service) that would adequately serve the purposes of the supervision? Third, only if non-carceral alternatives are inadequate may the court impose imprisonment.

Bearden was decided in the context of fines and restitution, but courts have applied its reasoning to monitoring fees as well. A Yale Law Journal comment noted the growing body of litigation seeking to extend Bearden challenges directly to electronic monitoring fee revocations. The practical problem, acknowledged by defense attorneys, is that the Bearden inquiry requirement is frequently not followed in practice. Busy courts sometimes revoke supervision on non-payment without conducting the ability-to-pay analysis the Constitution requires.

What Happens If You Cannot Pay?

The consequences of falling behind on monitoring fees depend heavily on the jurisdiction and the judge.

In the worst cases, a person may be found in violation of supervision conditions and returned to custody. The Fines and Fees Justice Center documented that failure to pay monitoring fees "can lead to extended periods of supervision, additional fees, or even jail." This creates a structural trap: people are placed on electronic monitoring in part because they cannot afford cash bail, and then they are charged daily fees they also cannot afford, with the risk of incarceration for non-payment.

In jurisdictions with ability-to-pay protections, the person or their attorney can request a fee waiver or hardship reduction hearing. In some states, the supervised person can ask the court to substitute community service or an alternative condition. Some private vendors offer sliding-scale rates, though the availability and terms vary and are rarely publicized.

Where a state or county has an indigency fund (Tennessee is the clearest example), a court finding of indigency routes payment responsibility to the public fund rather than the individual, subject to a minimum contribution from the person supervised.

The safest practical step for anyone who cannot afford monitoring fees is to raise the issue with an attorney immediately rather than simply not paying. Voluntary non-payment without communicating financial hardship to the court is more likely to be treated as willful non-compliance.

The Private Vendor Industry

The ankle monitor market is dominated by a small number of companies. BI Incorporated, now owned by the GEO Group (one of the country's largest private prison operators), is among the largest. Attenti, formed from the merger of BI with 3M Electronic Monitoring, serves many state and county contracts. Track Group, Sentinel Offender Services (now part of Offender Management Solutions), and SCRAM Systems are other significant players.

These companies are mentioned here as neutral industry context. This is not an endorsement of any vendor, and recordinglaw.com has no affiliation with any monitoring company.

Critics note that the private-vendor structure creates a financial incentive to extend supervision rather than end it, since each additional day of monitoring generates revenue. The Brennan Center described this as "how electronic monitoring incentivizes prolonged punishment." When a vendor contracts directly with the monitored person rather than with a government agency, there is also minimal external review of the rates charged or the accuracy of billing.

Recent Reforms Capping or Eliminating Fees

Fee reform is an active area of state legislative activity. The following reforms are documented as of early 2026:

California enacted successive reforms between 2020 and 2022 that expressly prohibit electronic monitoring fees at any stage of the criminal process. California is one of only two states with an outright prohibition. The reforms discharged more than $16.5 billion in court debt statewide.

Illinois eliminated user fees for electronic monitoring through the Pretrial Fairness Act, part of the SAFE-T Act package. The pretrial provisions took effect on September 18, 2023, making Illinois the first state to fully eliminate money bonds and removing the statutory authority to charge pretrial EM fees.

Oregon removed the statutory authorization for probation and parole fees, including language that had previously permitted electronic monitoring fees. Implementation varies at the county level, and some counties were still collecting fees as of the 2022 Fines and Fees Justice Center survey, so individuals in Oregon should verify current practice with local court staff or a defense attorney.

Oklahoma enacted HB 1460 in 2025, eliminating a fee of up to $300 per month for electronic monitoring administered by the state Department of Corrections GPS monitoring program. The reform came after an interim legislative study found that the fee was effectively uncollectable (only about $200,000 of $700,000 assessed was actually collected) and that it created serious reentry barriers.

Rhode Island prohibits EM fees for pretrial defendants but continues to allow post-sentencing fees.

Cook County, Illinois has undergone significant structural changes: the Sheriff's Office stopped accepting new enrollments in its pretrial EM program on April 1, 2025, and all new monitoring orders are handled by the Adult Probation Department under the unified post-Pretrial Fairness Act framework.

Tennessee has a state-run Alternative Electronic Monitoring Indigency Fund (AEMIF), which pays up to $170 per month per device for court-ordered monitoring when the supervised person is found indigent by the court, with the monitored person contributing at least $30 per month.

State-by-State Overview

Fees for electronic monitoring are most often set at the county or court level through vendor contracts, not by state statute. The table below reflects general statewide practice and any documented reforms as of 2026. Where no verified statewide fee structure exists, the cell notes "Varies by county/court." Do not treat any entry as a guaranteed rate; confirm current fees with your attorney or the supervising agency.

Not Convicted? You May Still Owe Fees

One of the most contested aspects of the offender-funded model is that pretrial monitoring fees accrue before any finding of guilt. A person accused of a crime, released on a monitoring condition, and later acquitted or whose charges are dismissed may nonetheless have paid hundreds or thousands of dollars in daily monitoring fees.

California's fee prohibition and Illinois's Pretrial Fairness Act both address this directly by eliminating pretrial fees altogether. In states without those protections, there is generally no statutory right to a refund of monitoring fees paid during a case that ends in acquittal or dismissal. This is an area where advocacy organizations have pushed for reform, and it remains contested in several states.
