If you missed the deadline after 90 days, you can contact the Marketplace and request a 60 day extension. Generally, if the Marketplace hasn’t received the requested information within 150 days and you didn’t already ask for an extension, the Marketplace will make a determination based on the information it has.  However, you may still be able to submit the requested information after the missed deadline and have your eligibility for premium tax credit applied. Contact the call center or ask a Navigator for help submitting your documentation as soon as you can.
