The vast majority of nearly 1 million Obamacare customers have received new tax forms — with about two weeks left until tax day.
The Centers for Medicare and Medicaid Services said that all but about 1,500 of the 820,000 who were initially sent botched forms have received corrected ones.
The problem with the 1,500 people left is they require additional case work, the agency said Thursday, declining to elaborate.
It is not clear at this time whether the taxpayers will get an extension for turning in their tax returns, which are currently due on April 15.
All taxpayers can automatically get a six-month extension, but they have to send in a form by tax day.
The 820,000 forms were sent to Obamacare customers who selected the second-cheapest silver plan, one of three plans available. The form incorrectly calculated the subsidy the customer was supposed to receive.
CMS announced last month that about 50,000 people already filed their returns on the incorrect form and either received too little or too much subsidies.
The Treasury Department said those taxpayers don’t need to file a new return, and if they got more subsidy than they should have, they don’t have to give anything back. Taxpayers who weren’t paid a large enough subsidy can file a new return to get what they’re owed.
CMS also announced that 36,000 people have signed up for Obamacare under healthcare.gov’s special enrollment period that started on March 15.
The administration has a special enrollment period until April 30 for people eligible for the law’s individual mandate penalty. The nearly $100 penalty went into effect last year.
However, the enrollment period is for taxpayers who find out they owe the 2014 penalty when they file their taxes. The extra time gives those taxpayers an opportunity to avoid the 2015 penalty, which is much higher.
