What Happens If Your Income Changes After You Enroll in a Marketplace Plan?

Life is not always predictable. A new job, a raise, a layoff, or a change in household size can all affect your income — and that income change can impact your ACA marketplace coverage and subsidies.

Here is what you need to know.

Why Income Changes Matter

Your ACA premium tax credit is calculated based on your estimated annual income. If your actual income turns out to be different from what you estimated, it can affect:

• Your monthly subsidy amount — you may be receiving too much or too little
• Your program eligibility — a significant income change could move you from marketplace coverage to Medicaid or vice versa
• Your tax liability — excess subsidies may need to be repaid when you file taxes

What to Do When Income Changes

Report the Change to Kynect

The most important step is to report the change as soon as it happens. Log into your Kynect account and update your income information. The system will recalculate your subsidy and eligibility.

Income Increases

If your income goes up, your subsidy may decrease, meaning your monthly premium could increase. If your income rises above the marketplace subsidy threshold, you may lose subsidy eligibility entirely.

Income Decreases

If your income drops, you may qualify for a larger subsidy. If it drops below the Medicaid threshold (138% FPL), you may need to transition to Medicaid, which provides more affordable coverage.

Household Size Changes

Adding or losing a household member (marriage, divorce, new baby, dependent moving out) also affects eligibility and subsidy calculations. Report these changes to Kynect as well.

• Report income changes to Kynect promptly — this keeps your subsidy accurate and avoids tax surprises.
• Income increases may reduce your subsidy and could trigger program eligibility changes.
• Income decreases may increase your subsidy or qualify you for Medicaid.

What Happens at Tax Time

When you file your annual tax return, the IRS compares your actual income to the estimated income used for your subsidy:

• If you received too much subsidy, you may owe some or all of it back (subject to repayment caps based on income)
• If you received too little subsidy, you will get the difference as a tax credit

Keeping Kynect updated throughout the year minimizes the gap between your estimated and actual subsidy.
