CMS Finalizes 2027 Marketplace Rules: What Employers and Consumers Need to Know

May 26, 2026

The Centers for Medicare & Medicaid Services (CMS) recently finalized the annual Notice of Benefit and Payment Parameters (NBPP) for Plan Year 2027, introducing several important policy updates that will impact health insurance exchanges, employers, brokers, and consumers nationwide.

At Cosmo Insurance Agency, our Legal and Government Affairs teams are already reviewing the details to help our clients stay informed, prepared, and ahead of the curve before Open Enrollment begins.

As your trusted partner, we want to share some of the key highlights from the finalized rule and what they could mean moving forward.

Key Changes in the CMS 2027 Final Rule

Increased Income Verification Requirements

Beginning in Plan Year 2027, consumers who attest to having an income above 100% of the Federal Poverty Level (FPL) may face additional verification requirements if trusted data sources suggest their actual income falls below that threshold.

This change is designed to strengthen eligibility verification processes and reduce improper enrollments in Marketplace coverage with premium tax credits.

For consumers, this means:

  • Additional documentation may be required during enrollment
  • Delays in coverage approval could occur if income cannot be verified promptly
  • Accurate income reporting will become even more important during the application process

Employers and brokers should be prepared to guide employees and clients through these enhanced verification steps to avoid disruptions in coverage.

Premium Tax Credit Eligibility Tightens

Another major change involves premium tax credit eligibility.

Currently, consumers may lose access to premium tax credits if they fail to file and reconcile their federal taxes for two consecutive years. Under the new rule, consumers who fail to file tax returns for just one year will lose eligibility for premium tax credits on the Federally Facilitated Marketplace (FFM) beginning in PY 2027.

State-Based Marketplaces (SBMs) will have until PY 2028 to implement this policy.

This update reinforces the importance of:

  • Filing federal tax returns on time
  • Reconciling Advance Premium Tax Credits (APTCs)
  • Educating Marketplace participants about compliance responsibilities

Consumers relying on Marketplace subsidies should pay close attention to tax filing deadlines to maintain eligibility for financial assistance.

Stricter Verification for Special Enrollment Periods (SEPs)

CMS is also increasing oversight for consumers enrolling through Special Enrollment Periods (SEPs).

Under the new rule:

  • Consumers using SEPs will face stricter pre-enrollment verification requirements
  • Documentation supporting qualifying life events may be required before coverage becomes effective

This policy aims to strengthen program integrity and reduce improper SEP usage.

Examples of qualifying life events may include:

  • Loss of employer coverage
  • Marriage or divorce
  • Birth or adoption of a child
  • Permanent relocation

Individuals enrolling outside the standard Open Enrollment period should expect more detailed verification procedures moving forward.

Expanded Flexibility for Non-Standardized Plans

The finalized rule also removes the current limit on non-standardized plan offerings on the Federally Facilitated Marketplace.

Previously:

  • Issuers could offer only two non-standardized plan designs per product network type

Beginning in PY 2027:

  • Issuers may offer an unlimited number of non-standardized plan designs

This change could lead to:

  • More plan options and customization
  • Increased competition among carriers
  • Greater complexity for consumers comparing plans

While additional choices can benefit consumers, navigating plan options may become more challenging without expert guidance.
