SEP deadline checker

Check official next steps after losing job-based coverage.

Tool purpose

Use this client-side tool to organize the dates and official links to verify after job coverage changes. The page exists to help a user organize the event, date, state, and official verification links before they share contact information with any private site.

Browser-only inputs

SEP deadline checker inputs stay in the browser and are not sent to a server-side calculator endpoint. The result can use coarse state, age band, income band, and date context, but public v0 does not retain identity, phone, email, SSN, prescription, doctor, or plan account information.

Official verification

SEP deadline checker outputs link back to official sources and label planning dates as estimates when they are derived from user-entered dates. The tool does not decide eligibility, recommend a plan, calculate a final Marketplace subsidy value, or route the user to a paid partner.

What to prepare

Before using SEP deadline checker, keep source documents nearby: coverage notices, COBRA packets, state marketplace routing, Medicaid or CHIP notices, Medicare timing sources, or employer-plan materials when relevant. The result is a checklist for official verification, not an enrollment application.
