Congressional Republicans are moving fast to overturn a D.C. Council tax overhaul right as residents are firing up their tax software, a clash that could throw refunds, filing deadlines and local systems into chaos in the middle of tax season.
At issue is the District's recent move to restore its child tax credit and break away from several controversial federal tax changes. If Congress succeeds in nixing the law, the Office of Tax and Revenue and private tax software companies would likely have to scramble to reprogram systems and rewrite instructions, with local officials warning that filing deadlines could slip into the fall.
The House on Feb. 4 approved H.J.Res.142, a joint resolution aimed at nullifying the D.C. Income and Franchise Tax Conformity and Revision Temporary Amendment Act of 2025. The Senate's companion, S.J.Res.102, has already been reported out of committee and placed on the Senate calendar. As recorded on Congress.gov, H.J.Res.142 passed the House, and Congress.gov shows that the Senate resolution was reported to the floor on Feb. 4. If both chambers ultimately approve a joint resolution and the president signs it, D.C.'s tax changes would be wiped off the books.
What D.C.'s Law Changed
In December the D.C. Council approved an emergency amendment that decoupled the District's tax code from many provisions of the One Big Beautiful Bill and used part of the resulting savings to restore and expand a local child tax credit and increase the earned-income credit. The measure carved the District out of about a dozen provisions, including changes to how tips and overtime are taxed and several corporate breaks that Council leaders said would have drained local revenue. These details were reported by The Washington Post.
How A Reversal Could Break Filing Season
D.C.'s chief financial officer has warned Congress that pulling the plug on the law mid-season would likely force the Office of Tax and Revenue to suspend filings while it reprograms tax-processing systems. Private vendors would also need months to update software, all of which could cost the city millions. The CFO's letter, included in the Congressional Record, projected that the timing of such a reversal could trigger about a $400 million cash-flow shortfall in the current fiscal year. Local business groups and the Council have issued similar alarms about the administrative mess that could follow. Congressional Record.
Money And Child Poverty Stakes
Supporters of the D.C. law say the Council designed the overhaul to protect hundreds of millions in local revenue and to steer a share of that money directly to families with children. The DC Fiscal Policy Institute has warned that undoing the Council's changes would strip the city of nearly $700 million and put at risk programs that aim to cut child poverty.

D.C. Officials Push Back
District officials have blasted the effort as federal overreach, saying the timing is especially damaging for residents trying to file their returns. "This resolution is both unprecedented and unsurprising - this is deliberate administrative and fiscal sabotage of the nation's capital," Del. Eleanor Holmes Norton said in a statement. Norton's office.
What To Watch And What To Do
For now, the Office of Tax and Revenue is still accepting returns and posting guidance for taxpayers and preparers. Residents are being urged to keep an eye on OTR notices and to check with their tax preparer about any credits they plan to claim. The OTR website lists phone numbers and information about the agency's walk-in center for questions. Office of Tax and Revenue. Local coverage and a short explainer are also available from WUSA9.
Whether Congress ultimately finalizes a repeal and the president signs it will decide the fate of the child tax credit for this filing season. City leaders say the outcome carries high stakes for low-income families and for the District's broader financial stability as the votes proceed on Capitol Hill.
