FAQ
Frequently Asked Questions
What income gets the biggest subsidy?
Premium tax credits cap your premium at a share of income — roughly 0–8.5% depending on earnings. In 2025, a single person earning ~$21,000–$32,000 can often get a robust Silver plan for $0–$10/month after subsidies.
Can immigrants use the marketplace?
Lawfully present immigrants (green cardPermanent Resident Card — The ID card proving lawful permanent resident status — live and work in the US permanently.Click for official info ↗ holders, visa holders, DACA, TPS, and others) can buy marketplace plans and get subsidies. Undocumented residents cannot use the federal marketplace but may access state programs or community clinics.
What happens if I miss open enrollment?
You must wait a full year unless you have a qualifying life event (losing job coverage, marriage, divorce, new baby, moving states). Short-term plans exist but do not cover pre-existing conditions.
