What amendment abolished poll taxes in federal elections?

The Twenty-fourth Amendment abolished poll taxes in federal elections, which were fees required to vote and often used as a barrier to restrict voting rights, particularly for African Americans and poorer citizens. Ratified in 1964, this amendment made it unconstitutional to impose such taxes in federal elections, thereby promoting greater access to the electoral process and reinforcing the principle of equal protection under the law. This was a significant step in the civil rights movement, aimed at eliminating discriminatory practices that suppressed voter turnout among marginalized groups.

In contrast, the Sixteenth Amendment relates to income tax, the Twentieth Amendment addresses the terms of office for federal officials, and the Twenty-second Amendment sets term limits for the President. None of these amendments pertain to voting rights or the specific issue of poll taxes.
