Which amendment abolished the poll tax in federal elections?

The Twenty-fourth Amendment abolished the poll tax in federal elections, which was a significant step in the civil rights movement aimed at eliminating barriers to voting. Ratified in 1964, this amendment made it unconstitutional to impose a tax on voting in federal elections, addressing the discriminatory practices that affected low-income individuals and marginalized groups, particularly African Americans in the southern states.

Prior to this amendment, poll taxes were used as a means to limit the voting rights of those who could not afford to pay the tax, effectively disenfranchising many citizens. The amendment was part of a broader effort to ensure that voting rights were accessible to all individuals, regardless of economic status.

Other amendments, such as the Fifteenth Amendment, which prohibits voter discrimination based on race, the Nineteenth Amendment, granting women the right to vote, and the Twenty-second Amendment, which limits presidential terms, do not specifically address the issue of poll taxes in elections, making the Twenty-fourth Amendment the correct choice regarding this particular question.
