What does this do?
HJRES 142 is a joint resolution in which Congress exercises its authority under the D.C. Home Rule Act to reject a law passed by the D.C. Council in December 2025. That local law was a temporary measure to align D.C. income and business taxes with updated federal tax rules, a process known as conformity. By passing this resolution, Congress has officially canceled the D.C. tax changes before they could take effect.
Who does it affect?
This affects residents who live and work in Washington, D.C., as well as businesses that operate there and pay D.C. income or franchise taxes. The D.C. Council, which passed the original local law, is the local governing body whose decision Congress has overturned.
Why does it matter?
Because the local law was canceled, D.C. tax rules will not reflect the conformity changes the D.C. Council intended to make. Residents and businesses may be required to follow older tax rules instead of the updated ones the local government had approved.
