Submission + - 800,000 Using HealthCare.gov Were Sent Incorrect Tax Data (nytimes.com)
The Obama administration, under heavy pressure from congressional Democrats, also announced that it would give several million people more time to buy health insurance so they could comply with federal law and avoid tax penalties.

Officials said they did not know why the error had occurred.
