Tex. Code of Criminal Procedure § 42.038

(a) In addition to any fine, cost, or fee authorized by law, a court that sentences a defendant convicted of a misdemeanor to serve a term of confinement in county jail and orders execution of the sentence may require the defendant to reimburse the county for the defendant's confinement at a rate of $25 a day.

(b) A court that requires a defendant convicted of a misdemeanor or placed on deferred adjudication for a misdemeanor to submit to a period of confinement in county jail as a condition of community supervision may also require as a condition of community supervision that the defendant reimburse the county for the defendant's confinement, with the amount of reimbursement determined as if the defendant were serving an executed sentence.

(c) A judge may not require reimbursement under this article if the judge determines the defendant is indigent based on the defendant's sworn statement or affidavit filed with the court. A court that requires reimbursement under this article may require the defendant to reimburse the county only for those days the defendant is confined after the date of conviction or on which a plea of guilty or nolo contendere was entered. The court may not require a defendant to reimburse the county for those days the defendant was confined after arrest and before the date of conviction or on which the plea of guilty or nolo contendere was entered.

(d) The court, in determining whether to order reimbursement under this article, shall consider:

(1) the defendant's employment status, earning ability, and financial resources; and

(2) any other special circumstances that may affect the defendant's ability to pay, including child support obligations and including any financial responsibilities owed by the defendant to dependents or restitution payments owed by the defendant to a victim.

(e) On the day on which a defendant who is required to reimburse the county under this article discharges an executed sentence of confinement or completes the period of confinement required as a condition of community supervision, the sheriff shall present to the defendant a bill computed by multiplying the daily rate of $25 times the number of days the defendant was confined in the county jail, not counting the day on which the execution of the sentence or the period of confinement began. For purposes of this subsection, a defendant who is confined in county jail for only a portion of a day is nonetheless considered to have been confined for the whole day.

(f) The court may require a defendant to reimburse the county under this article by paying to the sheriff the bill presented by the sheriff within a specified period or in specified installments. The end of the period or the last installment may not be later than:

(1) the end of the period of community supervision, if community supervision is ordered; or

(2) the fifth anniversary of the last day of the term of confinement, if the court does not order community supervision.
