Some Marketplace applicants qualify for a premium tax credit that can lower monthly premiums. Eligibility and amounts depend on the applicable rules and details such as household information, expected annual income, access to other coverage, location, and the plan selected.
Advance premium tax credits
Eligible consumers may choose to have all or part of an estimated credit paid in advance to an insurer to reduce monthly premiums. Because the advance amount is based on information available at application time, it is important to report changes and reconcile the amounts when required.
Cost-sharing reductions
Cost-sharing reductions may lower out-of-pocket costs for eligible people who enroll in a qualifying plan, generally a Silver plan. They are different from premium tax credits. Confirm the rules and plan options that apply to your year and circumstances.
Do not rely on blanket savings claims
A claim that all applicants get a $0 premium, or that a given income always produces a particular savings amount, is not reliable. Compare the actual plans and assistance shown by the official Marketplace after entering the required information.
