About 100,000 households in California are being asked to delay filing their taxes as they await new tax documents from the Covered California healthcare exchange.
Covered California spokesman James Scullary said anyone affected was told about a mix-up with their 1095-A forms by early February, and that corrected replacement forms are already on the way.
"What we told them to do is wait," Scullary said. "Forms should be in their hands by the end of this month or early March."
Of the 800,000 households that receive the forms, 100,000 contained the wrong information.

Scullary acknowledged the error, and said the linking of taxes and health care is a new process for everyone.
"It’s a learning curve," he said.
Nationally, 800,000 people who used the healthcare.gov site to purchase insurance in 2014 were affected.
