85% Rule in Oklahoma is harsh and will greatly extend the time a person spends in jail. In Oklahoma, a “10-year sentence” doesn’t always mean 10 years. For most crimes, inmates can earn “good time credits” or become eligible for parole after serving a fraction of their time—often as little as 25% to 33%.
However, for a specific list of serious offenses, Oklahoma law triggers the 85% Rule. This rule is one of the strictest sentencing laws in the country, and understanding it is vital if you or a loved one are facing felony charges in Tulsa.
What is the 85% Rule?
Under Oklahoma Statutes Title 21, Section 13.1, individuals convicted of certain “85% crimes” are legally required to serve at least 85% of their total court-imposed sentence before they even become eligible for a parole hearing.
Furthermore, for these specific crimes, you cannot use earned credits (for good behavior or work) to reduce your time served below that 85% floor.
Example: If a defendant is sentenced to 20 years for an 85% crime, they must spend at least 17 years behind bars before they can even be considered for parole. For a non-85% crime, that same person might be eligible for parole in roughly 5 to 7 years.
Which Crimes Fall Under the 85% Rule?
The list primarily includes violent and sexual offenses. As of 2026, the list has expanded to include several high-profile felonies. Key 85% crimes include:
- Homicide: First and second-degree murder, and first-degree manslaughter.
- Violent Assaults: Shooting with intent to kill, assault and battery with a deadly weapon, and aggravated assault and battery on a police officer.
- Robbery: First-degree robbery and robbery with a dangerous weapon.
- Sex Crimes: First-degree rape, forcible sodomy, and lewd molestation of a child.
- Drug Offenses: Aggravated trafficking in illegal drugs.
- Other Serious Felonies: First-degree arson, first-degree burglary, bombing, and human trafficking.
- Domestic Abuse: Since late 2025, domestic abuse by strangulation and domestic assault with a deadly weapon have also been added to this list.
Why This Matters for Your Defense
The 85% Rule completely changes the stakes of a criminal case. It impacts every stage of the legal process:
1. Plea Negotiations
A prosecutor might offer a shorter sentence for an 85% crime, but that “shorter” sentence might actually result in more physical time in prison than a longer sentence for a non-85% crime. Your attorney must calculate the “actual time served” to ensure you aren’t walking into a trap.
2. Jury Trials
In Oklahoma, juries are often instructed on the 85% rule so they understand the true weight of the sentence they are recommending.
3. The “Modernization” Factor
As of January 1, 2026, the Oklahoma Sentencing Modernization Act has reclassified many felonies into new tiers (Classes Y, A, B, C, and D). While this aims to make sentencing more consistent, it has not abolished the 85% rule for the most serious violent offenses. In fact, for certain Class C and D felonies, new “minimum time served” requirements are now in place.
Fight for a Lesser Included Offense
One of the most effective defense strategies is to negotiate with the district attorneys a charge down to a “lesser included offense” that does not carry the 85% requirement. For example, moving a charge from First-Degree Burglary (an 85% crime) to Second-Degree Burglary (not an 85% crime) can be the difference between a decade in a cell and a few years with a chance for early parole.
