Tax credits and subsidies designed to help people purchase health insurance are a permanent part of the Affordable Care Act and will not expire or change unless Congress specifically amends the law. Subsidies may increase based on national metrics accounting for premium and income growth. People who lose their jobs may be eligible for larger subsidies, and if the job included employer-sponsored insurance, the employee would become eligible to shop a public exchange during a special enrollment period.
