Which constitutional amendment abolished the poll tax?

The 24th Amendment abolished the poll tax in federal elections. Ratified in 1964, this amendment was a significant step toward ensuring fair voting practices by eliminating a financial barrier that had historically disenfranchised low-income individuals and minority groups. Poll taxes were fees required to be paid in order to vote, and they effectively limited access to the electoral process for many Americans. The amendment reflects a broader civil rights movement goal to enhance voter accessibility and protect the right to vote without economic discrimination. The impact of the 24th Amendment was further solidified by the Supreme Court's later decision in 1966, which ruled that poll taxes were unconstitutional in state elections as well.
