The administration sent incorrect tax information to 800,000 people who enrolled in health insurance through Obamacare's federal exchange and now the administration is telling those people to hold off filing their 2014 taxes.

The administration announced the glitch Friday on a HealthCare.gov blog post: "If you enrolled in a plan through the Health Insurance Marketplace for 2014, you should've received an important tax statement in the mail, called Form 1095-A. This statement has information you need to fill out your 2014 federal income tax return.

"Most people received a correct Form 1095-A. However, if we contact you because your Form 1095-A is incorrect, here's why. Some forms included the monthly premium amount of the second lowest cost Silver plan for 2015 instead of 2014, which needs to be corrected. The incorrect amount is listed in Part III, Column B of the Form 1095-A. We're working quickly to resolve this and any other issues with the 1095-A forms. This does not mean that your tax credit was incorrect; this is purely an error in what was printed on the form."
