The 24th Amendment to the U.S. Constitution bans poll taxes and any other tax as a condition for voting in federal elections. Ratified on January 23, 1964, it removed a financial requirement that states had used for decades to keep Black voters and low-income citizens from the ballot box.1Congress.gov. U.S. Constitution – Twenty-Fourth Amendment Two years later, the Supreme Court extended the same principle to state and local elections through the 14th Amendment, closing the loophole the text of the 24th had left open.
What the Amendment Says
The amendment is short. Section 1 forbids denying or limiting a citizen’s right to vote in a federal election because that person has not paid a poll tax or any other tax. Section 2 gives Congress the power to enforce the ban through legislation.1Congress.gov. U.S. Constitution – Twenty-Fourth Amendment
The phrase “or other tax” does real work. It stops governments from renaming a poll tax or swapping in a different financial requirement. If any tax obligation becomes a gateway to the ballot, it runs into this amendment.
Which Elections Are Covered
The amendment applies only to federal offices. Its text protects the right to vote in elections for:
- President and Vice President
- Presidential electors
- U.S. Senators
- U.S. Representatives
The protection covers both primaries and general elections.1Congress.gov. U.S. Constitution – Twenty-Fourth Amendment State and local contests are not named. That was a deliberate limit during drafting, driven by federalism concerns and by the political reality that a broader amendment might not have passed. The Supreme Court eventually closed the gap through a separate constitutional route.
Why Poll Taxes Existed
A poll tax was a flat annual fee, typically one or two dollars, that states required residents to pay before registering to vote. Southern states adopted poll taxes after Reconstruction as part of a broader plan to disenfranchise Black citizens without mentioning race. Combined with literacy tests, grandfather clauses, and other rules, poll taxes helped make voting practically impossible for many Black Americans and poor white residents.
The Supreme Court upheld the practice in 1937. In Breedlove v. Suttles, the Court unanimously approved Georgia’s one-dollar poll tax, treating voting as a state-granted privilege that states could condition as they saw fit.2Justia U.S. Supreme Court Center. Breedlove v. Suttles, 302 U.S. 277 (1937) That ruling gave states legal cover for nearly three decades.
By 1962, five states still charged poll taxes: Alabama, Arkansas, Mississippi, Texas, and Virginia. Virginia charged $1.50 per year and required proof of payment for the prior three years, turning a small fee into a real barrier for anyone living paycheck to paycheck.3Justia U.S. Supreme Court Center. Harper v. Virginia Board of Elections, 383 U.S. 663 (1966)
How It Was Ratified
Congress proposed the amendment in August 1962. South Dakota became the 38th state to ratify on January 23, 1964, crossing the three-fourths threshold. The process took roughly seventeen months.4Ronald Reagan Presidential Library & Museum. Constitutional Amendments – Amendment 24 – Elimination of Poll Taxes
Can States Get Around It? Harman v. Forssenius
Virginia tried almost immediately. After ratification, the state offered federal voters a choice: pay the poll tax as before, or file a notarized certificate of residence at least six months before the election. The Supreme Court struck the scheme down unanimously in Harman v. Forssenius (1965), holding that “the poll tax is abolished absolutely as a prerequisite to voting in federal elections, and no equivalent or milder substitute may be imposed.”5Justia U.S. Supreme Court Center. Harman v. Forssenius, 380 U.S. 528 (1965)
The rule from Harman has held ever since. A state cannot impose any material burden on voters solely because they refuse to pay a tax the Constitution forbids.
What About State and Local Elections? Harper v. Virginia
Virginia’s $1.50 poll tax stayed on the books for state elections after ratification, because the 24th Amendment did not reach them. Annie Harper, a Virginia resident who could not afford the tax, challenged it.
In Harper v. Virginia Board of Elections (1966), the Supreme Court ruled 6–3 that conditioning the right to vote on any fee violates the Equal Protection Clause of the 14th Amendment. Justice Douglas wrote that “fee payments or wealth, like race, creed, or color, are unrelated to the citizen’s ability to participate intelligently in the electoral process.”3Justia U.S. Supreme Court Center. Harper v. Virginia Board of Elections, 383 U.S. 663 (1966) The decision overruled Breedlove and ended poll taxes at every level of government.
How the Ban Is Enforced
Section 2 gave Congress express authority to enforce the amendment by statute. Lawmakers used it, together with their powers under the 14th and 15th Amendments, when they passed the Voting Rights Act of 1965.
Section 10 of the Voting Rights Act declared that poll taxes deny the constitutional right to vote, finding that they “preclude persons of limited means from voting” and in some areas have “the purpose or effect of denying persons the right to vote because of race or color.”6National Archives. Voting Rights Act (1965) The statute directed the Attorney General to sue any jurisdiction still enforcing poll taxes, so the federal government itself could act rather than waiting on individual lawsuits.
The amendment, Harper, and the Voting Rights Act now form overlapping layers of protection: a constitutional baseline for federal elections, an Equal Protection rule for state and local ones, and a federal enforcement tool for both.
Does It Still Matter Today?
Yes. The line between a legitimate obligation and an unconstitutional financial barrier to voting is still being drawn in court.
The most prominent recent example involves Florida. In 2018, voters approved a ballot measure restoring voting rights to most residents with felony convictions. The state legislature then required those individuals to pay all outstanding court fines, fees, and restitution before registering. A federal district court ruled in 2020 that court fees and costs function as taxes under the 24th Amendment and cannot be required as a condition of voting, and that the scheme also violated Equal Protection. The Eleventh Circuit stayed that ruling, and the Supreme Court allowed Florida to keep enforcing the payment requirement.
Voter identification laws raise similar questions. When a state requires a photo ID to vote but charges for the card, critics argue the fee is an indirect poll tax. Most states with strict ID requirements now offer a free ID option, likely in recognition of that constitutional risk. The question the 24th Amendment forces on every voting regulation remains the one it posed in 1964: does this rule make someone pay to vote?
