Republican control of the White House and Congress has produced no enacted legislation cutting federal long-term capital gains rates, which remain at 0/15/20 percent brackets for 2026. The July 2025 One Big Beautiful Bill Act made prior individual rate provisions permanent without altering capital gains taxation. Targeted proposals to double the primary residence exclusion, index gains for inflation, or create new exemptions have advanced only to the discussion or committee stage, facing reconciliation constraints, competing midterm priorities, and a compressed legislative calendar before year-end. Trader consensus at 95.5 percent for no change by December 31, 2026, reflects these procedural and timing barriers. A narrow lame-duck package expanding the home-sale exclusion or introducing indexing could still shift the outcome if Congress prioritizes housing supply measures after the November elections.
