How often during the year can I adjust my premium tax credit amount? What documentation is required to make an adjustment? How long after I request the adjustment will it take effect?

There is no limit to the number of times a person may report income, family or insurance-eligibility changes to the Marketplace. Changes that are reported by enrollees will be verified by the Marketplace. Then the Marketplace will send you a notice (called a redetermination notice) showing your revised eligibility for premium tax credits and cost-sharing reductions. In addition, people can always ask the Marketplace to provide them with a monthly advance premium credit below the amount the Marketplace determines based on the household’s income if they want to minimize the chance of needing to owe money at the end of the year.

The adjustment will take effect by the first day of the month following the date of the redetermination notice. For example, if an enrollee reports a change in income on June 25 and the Marketplace verifies the change and sends a redetermination notice to the enrollee on July 3, the change will be implemented on August 1.
