MNsure has yet to send about 1,300 tax forms to people who bought coverage last year through the state's health insurance exchange.

Forms were expected by early February, and more than 30,000 have been sent so far, MNsure officials said Friday.

But about 7,000 forms were held back as of mid-February for accuracy checks, and MNsure has been whittling down that number in recent weeks.

The tally of forms yet to be sent was 3,500 on Feb. 23. As of Friday, there were about 1,300 forms to go, said Jenni Bowring-McDonough, a MNsure spokeswoman.

The last forms include people with "complicated cases," she wrote in an e-mail.

"It's taking us longer than we would have liked to mail the forms, and it could potentially leave people waiting for the form to file their taxes in a tough position," wrote Joe Campbell, another spokesman for the agency, in an e-mail. "We apologize for anyone in this situation. Remaining forms should arrive shortly."

Called a 1095-A, the form lists the value of federal tax credits available to individuals who bought health insurance through MNsure during 2014. People who bought through MNsure will receive a form whether they received a tax credit or not.

The IRS says people should not file their taxes until they receive their form. And Chris Wittich, an accountant with Boyum & Barenscheer in Bloomington, said he would advise clients to wait before filing, rather than risk having to file an amended return.

About 40 percent of those who bought private health insurance during 2014 through MNsure received a tax credit.

The exchange estimates cumulative savings across the state of about $30.9 million, for about 16,100 people.

MNsure says it is sending out a total of about 35,000 forms, and each form can cover one or more enrollees in a household.
