ICHRA Implementation Checklist & Launch Timeline

Implementation sequence

A defensible ICHRA launch moves through feasibility, plan design, provider contracting, data readiness, required notice, employee education, individual enrollment, payroll and payment validation, and post-launch reconciliation. Skipping an earlier stage creates failures later.

Planning for 2027?Use the 2027 affordability guide and record your requirements in the evaluation brief. Keep older plan-year examples separate from current modeling.

Recommended planning window

A January 1 start aligns with annual individual-market open enrollment and common deductible resets. Existing employees generally need the required notice at least 90 days before the plan year, so a serious January launch should begin months earlier. Mid-year launches can work, but special enrollment, current group-plan termination, coverage effective dates, and employee communication require additional coordination. ^{source source}

Assign ownership

Workstream	Primary owner	Evidence of completion
Plan design and compliance	Employer with benefits/legal advisers	Approved plan documents, class logic, affordability analysis
Data and integrations	HR/payroll plus administrator	Validated fields, test files/API, exception handling
Employee communication	HR, broker, and administrator	Notice delivery, education materials, attendance, support plan
Enrollment and coverage	Employee with administrator/broker support	Plan confirmation, effective date, coverage substantiation
Payments and reimbursement	Administrator and finance/payroll	Reconciliation report and failed-payment procedure
Governance	Executive sponsor	Decision log, metrics, issues, corrective actions

Test failure paths before launch

An employee's insurer does not receive the premium.
A new hire's coverage effective date misses eligibility.
An HRIS termination does not reach the administrator.
An employee cannot find a critical provider or prescription.
A contribution amount is wrong for an age or family tier.
An employee expected a premium tax credit that an affordable offer blocks.
A reimbursement is denied because coverage proof is incomplete.

For each failure, define the owner, evidence required, response time, carrier interaction, employee communication, and correction record.

Launch standard

Do not call the project complete when enrollment closes.

The launch is complete only when coverage, payroll, contribution, carrier payment, and reimbursement records reconcile—and employees know where to go when the first exception occurs.
