Indiana Section 125 Plan Guide for Employers (2026)

Indiana employers often manage large hourly teams in manufacturing, logistics, and healthcare. A Section 125 plan gives immediate payroll tax savings and improves employee take‑home pay without changing carriers.

CMS reports 300,049 Marketplace plan selections in Indiana during the 2026 open enrollment period, which means employees are actively comparing employer coverage to individual options.


Indiana Coverage Context

Indiana uses HealthCare.gov and has expanded Medicaid. Employees will compare employer plans against Marketplace options, so net‑pay affordability matters. Section 125 directly improves affordability by moving eligible contributions pre‑tax.
