For your clients that received a subsidy in 2014 do they have to call in every year to keep the subsidy if their income hasn't changed. That's what Blue Cross told me but she sounded confused. I thought they only had to call if their income changed.
Did they check the "yes, you can access my IRS info" on the original app? If so, they are not required to do anything.
However.....
1. What if the SLCSP changed? There could be a different subsidy/premium
2. What if their plan was terminated and they are moved to a new plan?
3. What if they don't remember on the IRS box question?
Auto renewal is in place. What happens on Jan 1 with an auto renew is a whole different issue.
