A short period — usually 90 days — after your monthly health insurance payment is due. If you haven’t made your payment, you may do so during the grace period and avoid losing your health coverage. The grace period for health insurance is usually 90 days if both of the following are true: You have a Marketplace plan and qualify for advance payments of the premium tax credit. You’ve paid at least one full month’s premium during the benefit year so far. Note: The length of your grace period may be different if you don’t qualify for a premium tax credit. Contact your State Department of Insurance (DOI) for information on grace periods in your state.
