Which amendment is concerned with voting eligibility and taxation?

The Twenty-Fourth Amendment is concerned with voting eligibility and taxation by prohibiting the use of poll taxes in federal elections. This amendment, ratified in 1964, aimed to eliminate financial barriers that prevented low-income individuals from exercising their right to vote. Poll taxes were often used as a means of disenfranchising African American voters and poor white voters, particularly in the Southern states.

By removing the requirement of a poll tax, the amendment ensured that the right to vote could not be contingent upon an individual's ability to pay a tax, thus promoting greater inclusivity and equality in the electoral process. This amendment played a significant role in the broader civil rights movement, helping to dismantle systematic barriers to voting access.
