This bill requires the Treasury (IRS) and HHS to build a program that allows taxpayers to opt in on their federal income tax return to share selected return data with the Marketplace (Exchange). With taxpayer consent and a short supplemental form, relevant return information is transferred through a secure interface to enable Exchanges and insurance‑affordability programs (Medicaid, CHIP, Exchange premium tax credit programs, State basic health programs) to determine eligibility and — where available — enroll household members into minimum essential coverage that carries a zero net premium.
The law rewrites limited parts of the tax code (adding a disclosure exception to section 6103), expands permissible data sources (including the National Directory of New Hires), changes several MAGI/eligibility rules to stabilize coverage determinations (notably prior‑year income rules for January–April enrollments), and funds IT development and interagency data exchanges. The operational design emphasizes low friction: immediate data transfer, special enrollment periods tied to return filing, default enrollment into higher‑value zero‑premium plans, and a 30‑day reconsideration window — all of which reshape how eligibility, enrollment and reconciliation will work between IRS, Exchanges, and State programs.
At a Glance
What It Does
The bill creates a program (deadline Jan 1, 2028) for taxpayers to consent on their return to disclosure of relevant return information to Exchanges. Exchanges use that information plus limited supplemental details and third‑party data matches to determine eligibility and, if the person qualifies for a zero‑net‑premium plan and consents, automatically enroll them by default.
Who It Affects
Federal agencies (Treasury/IRS and HHS), state Medicaid and CHIP programs, Exchanges and their IT vendors, health insurers participating in Exchanges, tax return preparers, and taxpayers (including non‑filers who can still apply via other paths).
Why It Matters
It replaces many manual, paperwork‑heavy eligibility steps with data exchanges and automated decisioning, potentially increasing coverage uptake while shifting technical, privacy, and operational burdens onto federal and state systems and changing reconciliation risk for premium tax credits.

What This Bill Actually Does
The bill establishes a tax‑return based enrollment pathway: when individuals file federal returns (for tax years beginning after Dec 31, 2026), they may identify household members lacking coverage and consent to send ‘‘relevant return information’’ to the Marketplace. Consent can cover both disclosure and automated enrollment into minimum essential coverage provided at a zero net premium.
Taxpayers who consent must, in most cases, complete a short supplemental form (designed to be accessible across languages and disabilities) to collect items not on the return — state of residence, date of birth, employment and benefit availability, preferred contact methods, and authorization for future data disclosures to enable renewals.
Operationally, the Treasury must build a secure electronic interface for near‑real time transfers to Exchanges; the IRS, the taxpayer, or the preparer can trigger the transfer once the return meets processing criteria. Exchanges combine return data, the supplemental form, and other reliable third‑party sources (including wage and employment data, National Directory of New Hires matches, and employer coverage feeds) to minimize additional information requests.
If the Exchange finds the person eligible for Medicaid or CHIP, it conveys that information to the State for enrollment; if not eligible for Medicaid/CHIP, the Exchange assesses eligibility for advance premium tax credits and identifies qualified health plans with zero net premiums.Where multiple zero‑premium plans exist, Exchanges narrow the option set to those with the highest actuarial value (and may further restrict by generosity for benefits not subject to deductibles) and select a default plan following HHS‑prescribed procedures (which can include randomized issuer assignment). The bill requires Exchanges to notify individuals of default selections, give them a special enrollment period tied to the filing, and allow a 30‑day reconsideration window during which enrollees can disenroll or choose a lower cost‑sharing plan offered by the same issuer.
The bill also adds legal authority permitting targeted disclosure of return information (IRS Code section 6103 amended) for these purposes, sets data‑security and interagency agreement requirements, grants Exchanges access to new hire and wage feeds, and appropriates federal funds for IT development and operations. It includes an advisory committee and a study with a July 1, 2030 report to Congress on outcomes and pilot ideas.
The Five Things You Need to Know
Section 3 amends IRC section 6103 to add subsection (l)(23), authorizing disclosure of ‘‘relevant return information’’ to Exchanges—but limits use strictly to determining eligibility and facilitating enrollment.
Treasury must establish the tax‑return consent and transfer program by January 1, 2028; taxpayers may use it for returns filed for taxable years beginning after December 31, 2026.
Exchanges will default‑enroll consented individuals only into zero‑net‑premium plans; if multiple such plans exist, Exchanges restrict to the highest actuarial value plans and may further limit by out‑of‑deductible generosity.
Section 5 changes MAGI timing rules so applicants with eligibility dates in January–April can qualify based on prior calendar year modified adjusted gross income, intended to stabilize eligibility using accepted tax‑year data.
Section 6 gives insurance affordability programs access to the National Directory of New Hires (identity, employer, quarterly wages, unemployment compensation, and new‑hire flags) and requires programs to reimburse HHS for additional NDNH costs.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Tax‑return consent, supplemental form, and secure transfers
This section creates the core mechanism: taxpayers can, when filing returns, identify uncovered household members and elect (1) consent for disclosure of relevant return information to Exchanges and (2) enrollment of those members into zero‑net‑premium coverage. The Secretary of the Treasury must design the consent language, a short supplemental collection form (that cannot ask about citizenship, immigration status, or health status), and a secure electronic interface for transferring data. The provision also limits tax preparer liability for verifying information submitted solely to support enrollment and requires methods for immediate transfer to maximize same‑session determinations.
Exchange use of return data, eligibility rules, and default enrollment mechanics
Exchanges must use return data plus supplemental answers and reliable third‑party matches to reduce additional documentation burdens. If a household member is eligible for Medicaid/CHIP, Exchanges pass that finding to States for enrollment; otherwise Exchanges determine premium tax credit eligibility and whether zero‑premium qualified health plans exist. Where eligible zero‑premium plans exist, Exchanges choose a default plan from a narrowed set (highest actuarial value) and notify the individual; default enrollment occurs after a special enrollment period unless the individual selects or opts out. Exchanges must offer reconsideration within 30 days, and HHS sets weighting, randomization and opt‑out procedures.
Modernizing MAGI and premium‑tax‑credit timing to stabilize eligibility
The bill adjusts MAGI and premium tax credit mechanics to use a defined 'applicable taxable year' in several places, and specifically directs states to treat applicants with eligibility dates in January–April as eligible if their prior calendar year MAGI meets thresholds. It also adds safe‑harbor and reconciliation adjustments in 36B to reduce increases in repayment when advance payments align with reasonable return‑based income measures. These changes aim to reduce churn that arises when coverage seasons and tax seasons are misaligned.
Data infrastructure: National Directory of New Hires and employer coverage matches
HHS must make the National Directory of New Hires available to insurance affordability programs for identity, employer, quarterly wages, unemployment compensation and new‑hire indicators. The section explicitly authorizes use of public and private sources showing whether individuals are offered or receiving employer coverage (including 6055/6056 data) and requires interagency agreements and data‑security standards modeled on Medicaid information sharing rules. Programs reimbursing HHS for NDNH access cover the operational costs.
Funding IT build and cross‑agency transfers
Congress appropriates open‑ended sums to HHS and Treasury to build the IT and exchange infrastructure and to operate the program, with HHS authorized to transfer funds to Treasury, Exchanges, states, third‑party data vendors, and others. HHS and Treasury will set procedures for transfer requests, audits and appeals—recognizing the program’s heavy technical demands and expected multi‑party procurements.
Conforming edits to Medicaid, CHIP, and ACA eligibility statutes
The bill makes multiple conforming and enabling edits: it adjusts section 1137 rules for verification via reliable matches, amends ACA sections to allow receipt of return information and data matches in lieu of applicant‑provided data, and clarifies when Exchanges may rely on tax year information. These provisions change how States and Exchanges may accept attestations and replace some signature/attestation processes with electronic verification and data matches.
Advisory committee and evaluation
Treasury and HHS must convene an advisory committee with behavioral scientists, benefits and tax experts, stakeholders (consumers, issuers, providers, preparers) to guide technical design and outreach. HHS must study program impact and report recommendations by July 1, 2030, including pilot ideas such as automatic enrollment into employer group plans and alignment of open enrollment with tax filing cycles.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Uninsured taxpayers who file returns: they gain a low‑friction pathway to be evaluated for Medicaid, CHIP, or Exchange subsidies and may be auto‑enrolled into zero‑premium plans without needing to navigate separate applications.
- Exchanges and state program administrators: better access to standardized income and wage data should reduce manual verification work, enabling faster determinations and potentially lower administrative churn.
- Low‑income households with variable wages: prior‑year MAGI rules for January–April applicants create definable, tax‑year based eligibility that can reduce short‑term churn and unexpected coverage gaps.
- Consumers who accept default enrollment: those who would otherwise miss enrollment windows benefit from automatic placement into higher actuarial value zero‑premium plans and receive outreach and a reconsideration window.
- Health care providers and issuers participating in Exchanges: higher enrollment and reduced uncompensated care risk if more patients gain coverage through automated pathways.
Who Bears the Cost
- Treasury/IRS and HHS (and their contractors): must design, build, secure and operate new interfaces, consent flows, supplemental forms, and rapid data transfer capabilities—significant IT and program management costs.
- State Medicaid and CHIP agencies: will need to integrate new feeds, select among business‑rule packages, update enrollment workflows, and absorb operational complexity even though federal funds are provided for some costs.
- Health insurance issuers and Exchange‑operating entities: must accept auto‑enrollments, implement auto‑assignment rules, and support reconciliation and appeals processes; issuers may also face increased enrollment risk and pricing implications.
- Tax return preparers and software vendors: while not required to verify benefit‑related supplemental answers, they must incorporate consent language and transfer capabilities into preparer workflows and software, with attendant development and compliance costs.
- Consumers who do not file tax returns or lack SSNs (non‑filers, recent immigrants): they do not benefit from the tax‑return pathway and may face relative disadvantage unless state alternatives are robustly implemented.
Key Issues
The Core Tension
The central dilemma is between maximizing enrollment via low‑friction, data‑driven automation and protecting accuracy, privacy, and individual agency: automated, return‑based enrollment can expand coverage quickly and reduce paperwork, but it concentrates sensitive data, risks erroneous enrollments or denials from imperfect matches, and substitutes administrative defaulting for individual plan choice — a trade‑off with no technical fix and contested policy consequences.
The bill trades manual enrollment frictions for a large expansion of interagency data sharing and automated decisioning. That raises classic administrative tradeoffs: automated determinations reduce applicant burden but increase reliance on imperfect data matches (prior‑year AGI, employer feeds, new‑hire flags) that can misstate current eligibility—triggering complex remediation, appeals, and retroactive reconciliation.
The statute anticipates some of these problems (error reporting procedures, rights of notice and appeal, a reconsideration window) but leaves substantial design choices to HHS and Treasury: how aggressively to default‑enroll, how to weight randomization factors, what constitutes ‘‘reliable third‑party sources,’’ and how to operationalize state options for Medicaid/CHIP business rules.
Privacy and equity tensions are real. The bill expands IRC 6103 disclosures for a narrow purpose and layers on interagency agreements and data‑security standards modeled on Medicaid rules, but it also encourages broad transfers of wage and tax data, including social security numbers in some matches.
Even with strict-use limits, this architecture concentrates sensitive personally identifiable information across federal, state, Exchange, and private vendor systems, increasing the risk that breaches or misuse will have broad consequences. Moreover, the program is built around tax filers; people who do not file returns, who have unstable employment, or who face language or documentation barriers will depend on parallel state processes that the bill requires but does not fully resource or standardize.
