Why changes matter
A Marketplace application does more than help you pick a plan. It also helps determine whether you qualify for premium tax credits, which can lower your monthly premium, and cost-sharing reductions, which can lower some out-of-pocket costs if you enroll in a Silver plan.
Those savings are based on the household size and estimated income you report. If either changes, your savings can change as well. That is why people should check their Marketplace application after a move, a change in income, or a change in household members.
- Premium tax credits can lower monthly premiums.
- Cost-sharing reductions can lower deductibles, copayments, and coinsurance.
- Household size and income can affect both kinds of savings.
What the official guidance says to check
The official guidance says to report changes in expected income, household members, address, and other information in your Marketplace account. If you qualify for the premium tax credit, you can choose how much of it to use each month: all, some, or none.
For people who also qualify for cost-sharing reductions, the extra out-of-pocket savings are available only when you choose a Silver plan. If you enroll in another plan category, you may still use the premium tax credit, but you do not get those additional cost-sharing savings.
- Check whether your expected income has gone up or down.
- Check whether you added or lost a household member.
- Check whether you still want to use all, some, or none of your premium tax credit.
- Check whether you are shopping for a Silver plan if you want cost-sharing reductions.
How to update your Marketplace application
The source text gives a step-by-step path for updating your application. Log in to your Marketplace account, open your current application, and choose the option to report a life change. Then update the information that applies to you.
After you update, review your eligibility results before you pick or keep a plan. If you qualify for the premium tax credit, you may see an option to decide how much to lower your monthly premium. That lets you match the monthly help to your current situation.
If you do not expect a change, the source text says you do not have to change anything. But if your situation has changed, checking sooner can help you avoid using more tax credit than you qualify for or missing savings you may now be eligible for.
- Log in to your Marketplace account.
- Report a life change.
- Update income, household size, address, and other relevant details.
- Review your eligibility results.
- Choose how much premium tax credit to use, if eligible.
When savings can go up or down
The official guidance is straightforward: if your income goes up or you lose a household member, you will probably qualify for less premium tax credit. If your income goes down or you add a household member, you will probably qualify for more.
That matters because advance premium tax credit payments are reconciled when you file federal taxes. If you use more advance credit than you qualify for by year-end, you may have to pay the difference back. The source also says you can choose to use less or none of the tax credit each month if you are worried about that risk.
- Higher income or fewer household members may mean less premium tax credit.
- Lower income or more household members may mean more premium tax credit.
- Advance payments are settled later when you file federal taxes.
- You can choose to use less or none of the credit each month.
Hypothetical example
Imagine a family that enrolled in a Marketplace plan based on one income estimate and two household members. Later in the year, a new child joins the household or a job change lowers the family’s income. Based on the official guidance, that family should check the application again because the premium tax credit amount may change.
If that same family qualifies for cost-sharing reductions, they would also need to make sure they are looking at Silver plans to get those extra out-of-pocket savings. If they switch to a different metal level, they may keep the premium tax credit but lose the extra help with deductibles and copays.
- A change in income can change premium tax credit amounts.
- A change in household size can change premium tax credit amounts.
- Cost-sharing reductions require a Silver plan.
Common questions
Who should check their Marketplace savings after a life change?
Anyone whose household size, income, address, or other application details have changed should check. The official guidance says those changes can affect premium tax credits and, if eligible, cost-sharing reductions.
Can I still get premium tax credits if I do not want to use all of them each month?
Yes. The source text says you can use all, some, or none of the premium tax credit each month.
Do cost-sharing reductions work with every Marketplace plan?
No. The official guidance says cost-sharing reductions are available only if you choose a Silver plan.
What happens if I used too much advance premium tax credit?
According to the source text, you may have to pay back the difference when you file your federal taxes.
