This joint resolution, which became law in February 2026, cancels a temporary tax law that the District of Columbia Council passed in December 2025.^2,3 D.C. normally adopts federal tax changes automatically, and the council's law had separated D.C.'s tax code from parts of the 2025 federal tax and spending law known as the One Big Beautiful Bill Act, such as a larger standard deduction, a $6,000 deduction for people 65 and older, and deductions for tips, overtime pay and car loan interest.^2,3 Canceling the D.C. law generally brings those federal provisions back into D.C. tax law and also reverses the law's other changes, including its restoration of a D.C. child tax credit.^2,3 Under the District of Columbia Home Rule Act, laws passed by the D.C.
