Why Can the BOP Release Date Differ From a First Step Act or Conditional Release Date?
Several different dates appear on Bureau of Prisons documents, and they measure different things.

Short answer
A federal sentence computation starts with the sentence imposed and accounts for prior-custody credit under 18 U.S.C. section 3585 and good-conduct time under section 3624. Applied First Step Act credits and prerelease placement affect different parts of the picture, so a projected release date, a conditional date and prerelease information may not match. Figures also change as records are updated. The Bureau of Prisons performs the official computation; CaseSteps does not estimate any date.
Attorney review pending. This is general education, not legal advice.
Plain-English overview
A federal sentence computation begins with the sentence imposed, then accounts for prior-custody credit under 18 U.S.C. § 3585 and good-conduct time under 18 U.S.C. § 3624. First Step Act Time Credits that have been applied, and prerelease placement decisions, affect different parts of the picture.
Because these inputs are separate, records can display a projected release date, a conditional release date and prerelease information that do not match one another. The Bureau of Prisons controls the official computation.
Why this matters
Families frequently compare a date heard on a phone call with a date on a public locator and conclude that something is wrong. Often the two figures were never measuring the same thing.
Why this question causes confusion
Different documents and different people use similar words for different figures, and some figures are forward-looking projections that update as records change.
Applied First Step Act credits, prerelease placement in community conditions, and transfer to supervised release are also separate events. A person can move to community conditions well before the date that ends the term of imprisonment.
The governing distinctions
Sentence computation
Built from the sentence imposed, prior-custody credit under § 3585 and good-conduct time under § 3624.
Applied FSA credits
Credits actually applied toward prerelease custody or transfer to supervised release, which is separate from credits merely earned.
Prerelease placement
Time in community conditions such as a Residential Reentry Center or home confinement, decided individually by the Bureau of Prisons.
What can change the answer
- Recalculation by the Bureau of Prisons as records are updated.
- Changes in earned or applied First Step Act credits.
- Disciplinary findings affecting good-conduct time.
- Prior-custody credit questions under § 3585.
- Prerelease referral and placement decisions.
- Detainers and other holds.
Records to locate
- The sentence computation document.
- The current FSA Time Credit Assessment.
- Projected release information.
- Prerelease referral status.
- Do not upload any of these records to CaseSteps. Nothing here accepts files.
Questions for the unit team
- Which document shows the official computation?
- What does each date on that document mean?
- Are the credits shown as earned, applied, or projected?
- Has anything changed since the last recalculation?
- Has a prerelease referral been made?
What CaseSteps cannot do
CaseSteps does not calculate credits, good-conduct time, a release date, a PATTERN score or a placement date.
CaseSteps does not decide whether anyone is eligible, and does not predict what the Bureau of Prisons will do.
The Bureau of Prisons controls official sentence computation, credit records and placement decisions. Individual questions belong with the unit team and with qualified counsel.
Questions to discuss with counsel
- In general terms, what inputs go into a federal sentence computation?
- How is prior-custody credit different from good-conduct time?
- What records would explain the difference between two dates?
- Is there an administrative-review process if a computation appears incorrect?
- Is any part of this a question for the court rather than the Bureau of Prisons?
