Texas Government Code - GOV'T § 501.0081. Dispute Resolution: Time-Served Credits

(a) The department shall develop a system that allows resolution of a complaint by an inmate who alleges that time credited on the inmate's sentence is in error and does not accurately reflect the amount of time-served credit to which the inmate is entitled.

(b) Except as provided by Subsection (c), an inmate may not in an application for a writ of habeas corpus under Article 11.07, Code of Criminal Procedure, raise as a claim a time-served credit error until:

(c) Subsection (b) does not apply to an inmate who, according to the department's computations, is within 180 days of the inmate's presumptive parole date, date of release on mandatory supervision, or date of discharge. An inmate described by this subsection may raise a claim of time-served credit error by filing a complaint under the system described by Subsection (a) or, if an application for a writ of habeas corpus is not otherwise barred, by raising the claim in that application.
