ACA Special Enrollment Rules Tighten as Low-Income Year-Round Window Ends
Health insurance shoppers who miss the annual Affordable Care Act open enrollment window face a stricter special enrollment process in 2026 than in prior years. A nationwide special enrollment period that had allowed individuals earning up to 150% of the federal poverty level to sign up for marketplace coverage year-round officially ended on August 25, 2025, according to reporting from Solid Health Insurance.
The change means that, outside of open enrollment, consumers can generally only enroll if they've experienced a qualifying life event — a birth, marriage, job loss, or similar change — and act within the standard 60-day window that follows.
Regulators have also moved toward requiring documentation for a much larger share of special enrollment applications. The Georgetown University Center on Health Insurance Reforms noted in its 2026 open enrollment outlook that new federal policies "limit special enrollment periods (SEP), expose consumers to unexpected tax liability, and reduce covered benefits," part of a broader tightening across ACA marketplaces this year, per the Center on Health Insurance Reforms.
Consumers who believe they qualify for a special enrollment period are advised to gather supporting documents — such as a marriage certificate, termination letter, or birth certificate — before starting an application, since incomplete submissions can delay coverage start dates under the newer verification-first process.
