The Duplication Scoring Act of 2025 amends 31 U.S.C. § 719 to require the Government Accountability Office (Comptroller General) to analyze each bill or joint resolution reported by a congressional committee for the risk that it would create a new federal program, office, or initiative that duplicates or overlaps with matters GAO has previously identified as duplication or overlap. When GAO finds a risk, it must identify the new item, cite the bill section establishing it, and point to the prior GAO duplication-and-overlap report that identified the existing feature.
GAO then sends that information to the Director of the Congressional Budget Office (CBO) and the reporting committee and publishes it on GAO’s website.
The bill lets the CBO include GAO’s analysis as a supplement to its cost estimate under section 402 of the Congressional Budget Act, and it includes a timing backstop allowing CBO to submit the supplement later if GAO misses the CBO estimate deadline. The law’s effective date is tied to an OMB website update or, at latest, the start of a new Congress one year after enactment.
The change formalizes GAO’s duplication work into the congressional scoring process, creating new transparency — and new timing and resource questions — for committees, CBO, GAO, and agencies drafting or defending programs.
At a Glance
What It Does
Requires GAO to review every bill or joint resolution reported by a committee for risks of creating programs that duplicate or overlap with areas GAO previously identified, to identify the section and name of any new duplicative feature, and to publish and send that information to CBO and the reporting committee. Permits the CBO Director to add GAO’s findings as a supplement to CBO’s estimate and provides a procedure for late supplements if GAO misses CBO’s initial estimate deadline.
Who It Affects
Applies to any committee-reported bill or joint resolution (including actions by Appropriations and Budget committees), the Government Accountability Office, the Congressional Budget Office, reporting committees and their staff, and federal agencies that run programs potentially implicated by duplication findings. OMB is implicated only for the statute’s effective-date trigger.
Why It Matters
This bill integrates GAO’s annual duplication-and-overlap work into the legislative scoring process, increasing transparency about potential redundancies and giving CBO an official channel to attach duplication analysis to cost estimates. In practice, it could change drafting behavior, increase pre-reporting review, and create new timing pressures across GAO, CBO, and committee workflows.

What This Bill Actually Does
The bill adds a new subsection to 31 U.S.C. § 719 that creates definitional guardrails and a required process. It narrows the universe of duplication concerns to those GAO has already identified in its recurring duplication-and-overlap reports (the statute references the GAO annual report produced under the debt-limit joint resolution).
For any bill or joint resolution reported by a committee, GAO must assess whether the measure creates a risk of a new program, office, or initiative that would duplicate or overlap with an existing item GAO has identified.
If GAO decides the risk is sufficient to warrant action, it must (1) name the prospective new program/office/initiative, (2) point to the exact bill section where it is established, and (3) cite the prior GAO duplication-and-overlap report that identified the existing feature. GAO must then transmit that package to the CBO Director and to the committee that reported the bill, and publish the material on GAO’s website.
The bill phrases GAO’s duty as "to the extent practicable," which preserves some discretion over depth and timing of reviews.On the CBO side, the Director may include GAO’s submission as a supplement to the CBO estimate prepared under section 402 of the Congressional Budget Act of 1974. The bill also anticipates timing mismatches: if GAO hasn’t provided its information by the date CBO submits its estimate, CBO may later prepare and submit the GAO material as a supplement once it receives it.
The statute does not create an enforcement mechanism to stop a bill from proceeding; it creates disclosure and reporting channels intended to inform deliberations.Finally, the law’s effective date is not a fixed calendar day. Implementation becomes effective either 60 days after OMB updates certain information on its website under 31 U.S.C. § 1122(a) or when a new Congress begins after one year post-enactment, whichever is earlier.
That linkage can delay the operational start and create uncertainty about when GAO will begin routine reviews.
The Five Things You Need to Know
The bill requires GAO to analyze every bill or joint resolution reported by any congressional committee for the risk it would create a new program, office, or initiative that duplicates or overlaps with items GAO previously identified.
GAO must identify the name of the new feature, the specific bill section that creates it, and the GAO duplication-and-overlap report that identified the existing overlapping feature.
GAO must send its findings to the Director of the Congressional Budget Office and to the committee that reported the bill, and it must publish the findings on GAO’s website.
The CBO Director may include GAO’s findings as a supplement to the CBO estimate under section 402 of the Congressional Budget Act; if GAO misses CBO’s estimate date, CBO may submit GAO’s information later as a supplement.
Implementation is delayed until either OMB updates specified website information and 60 days elapse, or until the start of a new Congress that begins after one year following enactment, creating an uncertain effective-date window.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
States the Act’s short title as the "Duplication Scoring Act of 2025." This is purely nominal, but establishes the bill’s framing around duplication scoring, which matters for how agencies and offices refer to the new process internally and in guidance.
Key definitions that limit scope
Defines critical terms: "covered bill or joint resolution" (any bill or joint resolution reported by any committee, explicitly including Appropriations and Budget), "Director" (CBO Director), "existing duplicative or overlapping feature" (limited to items GAO has identified in its annual duplication-and-overlap report), and "new duplicative or overlapping feature" (a new program/office/initiative created by the covered bill that would duplicate an existing GAO-identified feature). These definitions deliberately tether the new review to GAO’s prior work, narrowing the scope of what GAO must flag.
GAO must assess reported bills and produce specified outputs
Requires GAO, "to the extent practicable," to determine whether a reported bill risks creating a new duplicative or overlapping feature. When warranted, GAO must (i) name the new feature, (ii) identify the bill section that establishes it, and (iii) cite the GAO report documenting the existing overlapping feature. GAO must submit this package to the CBO Director and the reporting committee and publish it on GAO’s website. The statutory language creates a transparent record but stops short of mandating a full programmatic or cost analysis by GAO.
CBO may add GAO’s findings to its estimates; timing backstop
Authorizes the CBO Director to include GAO’s submission as a supplement to the CBO estimate prepared under section 402 of the Congressional Budget Act. If GAO has not provided its material by the time CBO submits its estimate, the bill instructs CBO that it may prepare and submit the GAO information as a supplement on the date GAO later supplies it. This creates a formal path for duplication analysis to accompany scoring while allowing CBO to meet statutory estimate deadlines.
Effective date tied to OMB or the next Congress
Specifies the amendment’s effective date: either 60 days after OMB updates information on its website under 31 U.S.C. § 1122(a) or on the date a new Congress begins after one year following enactment, whichever is earlier. That linkage to OMB’s website update (a separate administrative action) means implementation timing could be uncertain and dependent on executive-branch steps outside GAO and CBO control.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Reporting committees and congressional staff — Gain an external, GAO-backed flagging mechanism that can surface redundancy risks before final passage, supporting more informed markup and amendment strategy.
- Congressional Budget Office — Receives structured, published input that it may attach to cost estimates, improving the factual record CBO can cite about program overlap when scoring legislation.
- Existing federal program managers and operating agencies — Benefit from earlier notice and potential prevention of duplicative initiatives that would divert funding, reduce confusion, or complicate administration.
- Oversight bodies and taxpayers — Gain transparency when GAO identifies potential redundancy, which can inform oversight, public debate, and efforts to reduce wasteful or fragmented programs.
Who Bears the Cost
- Government Accountability Office — Faces increased workload and potential need for resources to perform routine pre-publication reviews for every committee-reported bill, especially given the "to the extent practicable" caveat that invites judgment calls.
- Congressional Budget Office — May face timing and analytical burdens to incorporate GAO input into CBO estimates or to prepare and file supplements after an initial estimate, complicating schedule-driven workflows.
- Committee staff and legislative drafters — May incur additional drafting and pre-reporting coordination costs to respond to or avoid GAO-identified duplication, and could face more friction in the markup process.
- Federal agencies — May need to prepare defensive analyses, respond to duplication findings, or revise proposed implementations, imposing program-level administrative costs even when a duplication flag is advisory.
Key Issues
The Core Tension
The central tension is between preventing wasteful duplication through a mandatory disclosure channel and preserving the speed and resource constraints of the legislative scoring process: the bill increases transparency about overlap but imposes new analytic and timing burdens on GAO, CBO, committees, and agencies without providing new resources or enforcement measures.
The bill embeds GAO’s duplication work into the legislative scoring process but leaves several key implementation choices unresolved. First, the statute confines "existing duplicative or overlapping features" to items GAO has already identified in its annual reports, so novel overlaps that GAO has not previously cataloged could escape review.
Second, GAO’s duty is qualified by "to the extent practicable," which creates discretion that will matter in tight timeframes; GAO must decide how deep a review it can reasonably perform for every committee-reported bill without additional resources. Third, the statute creates no substantive enforcement mechanism — GAO’s findings are informational, not vetoes — so the practical impact depends on whether committees and CBO choose to act on the information.
Timing is the other major complication. CBO has statutory deadlines for estimates; the bill permits CBO to add GAO input as a supplement if GAO is late, but late supplements may be less effective in real-time deliberations.
The effective-date tie to an OMB website update creates administrative uncertainty about when GAO’s obligation begins. Finally, the publication requirement could politicize duplication flags: public naming of potential overlap may prompt rapid stakeholder reaction and pressure on committees and agencies, with uncertain effects on legislative speed and program design.
