EXPLAINER: Inside South Carolina’s Two-Year Legislative Deadline

It’s the final stretch for South Carolina lawmakers. In the second year of a two-year legislative session, time becomes the most powerful force shaping what does—and doesn’t—become law. While some bills pass early, many spend months moving between House and Senate committees, gathering debate and amendments along the way. As the session nears its end, the pace quickens and the pressure mounts.

South Carolina’s General Assembly operates on a two-year cycle, with 124 House members elected every two years and 46 Senators elected every four. Bills that don’t cross the finish line by the end of the second year don’t carry over—they expire. When the clock strikes 5 p.m. on the second Thursday in May, unfinished legislation is effectively erased, forcing lawmakers to start over in the next session.

This is why the final weeks matter. With the clock ticking, lawmakers race to move legislation from debate to decision—knowing that once time runs out, the window closes until a new General Assembly begins.
