Which amendment states that Congress cannot receive a pay raise until after the next election?

The 27th Amendment to the United States Constitution specifically addresses the issue of congressional pay raises. It was ratified in 1992, though it was originally proposed in 1789. The wording of the amendment clarifies that any change in the compensation for members of Congress does not take effect until after the following general election. This provision was established to ensure that lawmakers could not immediately benefit from a pay raise they voted for themselves, essentially promoting accountability and preventing potential conflicts of interest involving financial gain. This mechanism encourages Congress to consider the implications of pay increases on their constituents rather than acting solely in their own interest.

In contrast, the other amendments listed do not pertain to congressional salary adjustments. The 25th Amendment deals with presidential succession and disability, the 26th Amendment grants the right to vote at 18 years of age, and the 24th Amendment prohibits poll taxes in federal elections. Each of these focuses on different aspects of governance or civil rights, thus reinforcing the significance of the 27th Amendment's unique role regarding congressional compensation.
