delivered the opinion of the Court.

Petitioner accumulated fines of $425 on nine convictions in the Corporation Court of Houston, Texas, for traffic offenses. He was unable to pay the fines because of indigency^[1] and the Corporation Court, which otherwise has no jurisdiction to impose prison sentences,^[2] committed him to the municipal prison farm according to the provisions of a state statute and municipal ordinance^[3] which required that he remain there a suffi[*397] cient time to satisfy the fines at the rate of five dollars for each day; this required that he serve 85 days at the prison farm. After 21 days in custody, petitioner was released on bond when he applied to the County Criminal Court of Harris County for a writ of habeas corpus. He alleged that: “Because I am too poor, I am, therefore, unable to pay the accumulated fine of $425.” The county court held that “legal cause has been shown for the imprisonment,” and denied the application. The Court of Criminal Appeals of Texas affirmed, stating: “We overrule appellant’s contention that because he is too poor to pay the fines his imprisonment is unconstitutional.” 445 S. W. 2d 210 (1969). We granted certiorari, 399 U. S. 925 (1970). We reverse on the authority of our decision in Williams v. Illinois, 399 U. S. 235 (1970).

The Illinois statute involved in Williams authorized both a fine and imprisonment. Williams was given the maximum sentence for petty theft of one year’s imprisonment and a $500 fine, plus $5 in court costs. The judgment, as permitted by the Illinois statute, provided that if, when the one-year sentence expired, Williams did not pay the fine and court costs, he was to remain in jail a sufficient length of time to satisfy the total amount at the rate of $5 per day. We held that the Illinois statute as applied to Williams worked an invidious discrimination solely because he was too poor to pay the fine, and therefore violated the Equal Protection Clause.

Although the instant case involves offenses punishable by fines only, petitioner’s imprisonment for nonpay[*398] ment constitutes precisely the same unconstitutional discrimination since, like Williams, petitioner was subjected to imprisonment solely because of his indigency.^[4] In Morris v. Schoonfield, 399 U. S. 508, 509 (1970), four members of the Court anticipated the problem of this case and stated the view, which we now adopt, that

“the same constitutional defect condemned in Williams also inheres in jailing an indigent for failing to make immediate payment of any fine, whether or not the fine is accompanied by a jail term and whether or not the jail term of the indigent extends beyond the maximum term that may be imposed on a person willing and able to pay a fine. In each case, the Constitution prohibits the State from imposing a fine as a sentence and then automatically converting it into a jail term solely because the defendant is indigent and cannot forthwith pay the fine in full.”

Our opinion in Williams stated the premise of this conclusion in saying that “the Equal Protection Clause of the Fourteenth Amendment requires that the statu[*399] tory ceiling placed on imprisonment for any substantive offense be the same for all defendants irrespective of their economic status.” 399 U. S., at 244. Since Texas has legislated a “fines only” policy for traffic offenses, that statutory ceiling cannot, consistently with the Equal Protection Clause, limit the punishment to payment of the fine if one is able to pay it, yet convert the fine into a prison term for an indigent defendant without the means to pay his fine. Imprisonment in such a case is not imposed to further any penal objective of the State. It is imposed to augment the State’s revenues but obviously does not serve that purpose; the defendant cannot pay because he is indigent and his imprisonment, rather than aiding collection of the revenue, saddles the State with the cost of feeding and housing him for the period of his imprisonment.

There are, however, other alternatives to which the State may constitutionally resort to serve its concededly valid interest in enforcing payment of fines. We repeat our observation in Williams in that regard, 399 U. S., at 244-245 (footnotes omitted):

“The State is not powerless to enforce judgments against those financially unable to pay a fine; indeed, a different result would amount to inverse discrimination since it would enable an indigent to avoid both the fine and imprisonment for nonpayment whereas other defendants must always suffer one or the other conviction.

“It is unnecessary for us to canvass the numerous alternatives to which the State by legislative enactment — or judges within the scope of their authority — may resort in order to avoid imprisoning an indigent beyond the statutory maximum for involuntary nonpayment of a fine or court costs. Appellant has suggested several plans, some of which are[*400] already utilized in some States, while others resemble those proposed by various studies. The State is free to choose from among the variety of solutions already proposed and, of course, it may devise new ones.” ^[5]

We emphasize that our holding today does not suggest any constitutional infirmity in imprisonment of a defendant with the means to pay a fine who refuses or neglects to do so. Nor is our decision to be understood[*401] as precluding imprisonment as an enforcement method when alternative means are unsuccessful despite the defendant’s reasonable efforts to satisfy the fines by those means; the determination of the constitutionality of imprisonment in that circumstance must await the presentation of a concrete case.

The judgment of the Court of Criminal Appeals of Texas is reversed and the case is remanded for further proceedings not inconsistent with this opinion.

It is so ordered.

Mr. Justice Black concurs in the result.

Mr. Justice Harlan concurs in the judgment of the Court on the basis of the considerations set forth in his opinion concurring in the result in Williams v. Illinois, 399 U. S. 235, 259 (1970).
