Which amendment abolished poll taxes in federal elections?

The 24th Amendment abolished poll taxes in federal elections, which had been used as a means to restrict voting rights, particularly among low-income individuals and marginalized groups. Ratified in 1964, this amendment made it unconstitutional to require payment of a tax to vote in any federal election. The significance of this action lies in its role in the broader civil rights movement, as it aimed to eliminate barriers that hindered the ability of certain populations to engage in the electoral process.

In contrast, other amendments listed either address different voting rights issues or pertain to other aspects of governance. The 26th Amendment, for instance, lowered the voting age to 18, while the 22nd Amendment instituted term limits for the presidency. The 15th Amendment aimed to prevent racial discrimination in voting but did not directly tackle financial barriers. Thus, the focus of the 24th Amendment on poll taxes specifically identifies it as the amendment that abolished this requirement for federal elections.
