The passage of the One Big Beautiful Bill Act in July 2025, which permanently extended key 2017 Tax Cuts and Jobs Act business provisions while leaving the corporate rate at 21 percent, has anchored trader expectations against any further reduction before 2027. With the reconciliation process concluded and no active legislative vehicle advancing a rate cut, congressional attention has shifted toward tariff implementation and deficit management amid Republican priorities. Recent developments, including regulatory adjustments that effectively lowered some corporate liabilities without statutory rate changes, have not altered the core rate structure. This timeline leaves limited opportunity for new tax legislation in the remaining months of 2026, consistent with the 92.5 percent implied probability assigned to no additional cut occurring.
