If you're enrolled in a Marketplace plan and your income or household change, you should update your application with income and household changes as soon as possible.
These changes — like higher or lower income, adding or losing household members, or getting offers of other health coverage — may affect the coverage or savings you’re eligible for.
Use this tool from the IRS to see how income and household changes can affect your savings.
Some changes — like starting Medicare coverage or getting a job-based insurance offer — require you to cancel your Marketplace plan. Or you may want to cancel coverage for another reason.
