Five Supreme Court decisions do most of the work of defining the 24th Amendment: Harman v. Forssenius (1965), Harper v. Virginia Board of Elections (1966), United States v. Texas (1966), Crawford v. Marion County Election Board (2008), and Jones v. Governor of Florida (2020). Ratified on January 23, 1964, the 24th Amendment bars the federal government and the states from conditioning the right to vote in federal elections on payment of a poll tax or any other tax.1Congress.gov. U.S. Constitution – Twenty-Fourth Amendment The court cases interpreting the 24th Amendment have decided what counts as a poll tax, whether states can offer alternatives to paying one, and whether newer financial conditions on voting fall within the ban.
Harman v. Forssenius (1965)
Virginia was the first state to test the amendment’s limits. Rather than drop its poll tax for federal elections outright, Virginia gave voters a choice: pay the tax, or file a notarized or witnessed certificate of residence at least six months before the election.2Justia U.S. Supreme Court Center. Harman v. Forssenius, 380 U.S. 528 (1965)
The Supreme Court rejected the workaround. Chief Justice Warren, writing for the Court, held that the 24th Amendment abolished the poll tax “absolutely as a prerequisite to voting in federal elections” and barred states from imposing any “equivalent or milder substitute.” The certificate was a penalty aimed at voters who exercised their right not to pay, and the state’s claim that it helped verify residency did not save it: “constitutional deprivations may not be justified by some remote administrative benefit to the State.”
The rule that came out of Harman is straightforward. A state cannot replace the poll tax with a burden triggered by non-payment, no matter how reasonable the alternative sounds.
Harper v. Virginia Board of Elections (1966)
The 24th Amendment reaches only federal elections. States were still free after 1964 to charge poll taxes for governor’s races, state legislative contests, and local elections. Harper closed that gap, though on 14th Amendment grounds rather than under the 24th.
Annie Harper, a Virginia resident, could not afford the state’s $1.50 poll tax for state elections. She argued that the fee violated the Equal Protection Clause. In a 6-3 decision by Justice Douglas, the Court agreed.3Justia U.S. Supreme Court Center. Harper v. Virginia Bd. of Elections, 383 U.S. 663 (1966) A state violates equal protection, the Court held, “whenever it makes the affluence of the voter or payment of any fee an electoral standard.” Wealth, the majority said, has no more relevance to voter qualifications than race or creed.4Supreme Court of the United States. Harper v. Virginia Board of Elections
The right to vote was treated as fundamental, and the state’s interest in revenue could not justify barring anyone from the polls. After Harper, poll taxes were unconstitutional at every level of government, whether measured against the 24th Amendment or the 14th.
United States v. Texas (1966)
The same year, the federal government went on offense. Section 10 of the Voting Rights Act of 1965 declared that poll taxes deny the right to vote because of race in some areas and directed the Attorney General to sue any jurisdiction still enforcing one.5Office of the Law Revision Counsel. 52 USC 10306 – Poll Taxes A three-judge district court struck down Texas’s poll tax, and the Supreme Court affirmed in a brief per curiam opinion citing Harper.6Justia U.S. Supreme Court Center. Texas v. United States, 384 U.S. 155 (1966)
The reasoning was thin because it did not need to be thick. What mattered was that the Justice Department could initiate the litigation itself. Individual voters were no longer the only enforcement mechanism.
Crawford v. Marion County Election Board (2008)
Four decades later, voter identification laws raised a new question: when a voter has to spend money to obtain the documents needed for a “free” ID, is that a poll tax? Indiana required in-person voters to show government-issued photo ID. The ID itself was free, but the underlying documents, such as a birth certificate, were not.
The Supreme Court upheld the law in a fractured decision. Justice Stevens, writing for a three-justice plurality, applied a balancing test rather than the strict scrutiny of Harper. The state’s interest in preventing fraud and protecting election integrity was “sufficiently weighty to justify the limitation,” and the burden of obtaining a free ID was too small to outweigh it.7Justia U.S. Supreme Court Center. Crawford v. Marion County Election Bd., 553 U.S. 181 (2008) The Court declined to apply the poll-tax standard, finding that voter ID requirements serve a different purpose than raising revenue.
Justice Souter’s dissent argued the burden was not minor for elderly, low-income, and disabled voters facing travel time, lost wages, and document fees. The majority left the door open to future challenges if particular voters could show a severe individual burden, but no such challenge has succeeded at the Supreme Court since.
Jones v. Governor of Florida (2020)
The most recent major test came from Florida. In 2018, Florida voters passed Amendment 4 restoring voting rights to most people with felony convictions once they completed “all terms of their sentence.” The legislature defined that phrase to include payment of all fines, fees, and restitution, which in many cases ran into the thousands of dollars. Plaintiffs argued this was a modern poll tax.
A federal district court agreed. The Eleventh Circuit, sitting en banc, reversed. Chief Judge William Pryor, writing for the majority, drew a sharp line between poll taxes and criminal sentence requirements. Fines paid as punishment and restitution paid to victims are not taxes, the court held, and the 24th Amendment prohibits only taxes.8Justia. Jones v. Governor of Florida, No. 20-12003 (11th Cir. 2020) The court also distinguished Florida’s scheme from Harper, reasoning that completing a criminal sentence is “highly relevant to voter qualifications” in a way that paying a flat fee to vote is not.
Four judges dissented. Advocates continue to argue that criminal fees function identically to poll taxes for people who cannot pay, and that the drafters of the 24th Amendment intended to eliminate wealth-based barriers to voting regardless of label. The Supreme Court declined to hear the case, so the Eleventh Circuit’s reasoning stands within that circuit without being adopted as a national rule. Whether financial obligations tied to the criminal justice system can constitutionally block someone from the ballot remains an open question.
What the Cases Add Up To
The through-line is a single question: does the requirement make the ability to vote depend on the ability to pay? Harman answered yes for procedural substitutes designed to punish non-payment. Harper answered yes for state-level poll taxes under the Equal Protection Clause. United States v. Texas gave the federal government a tool to enforce those answers directly. Crawford and Jones show the harder cases: where a state can plausibly describe the payment as something other than a voting fee (an ID rule, a criminal sentence), the requirement has so far survived. The 24th Amendment’s core meaning is settled. Its edges are still being litigated.
