As usual, bad news from the government went out late on aFriday. Or maybe it was good news/bad news, at least for sometaxpayers.

The culprit in this case: the IRS, which sent forms to taxpayerswho received Obamacare premium subsidies in 2014. The formsare used to determine if an individual with health coverage a)owes money to the feds because the subsidy wastoo high; b) has money coming back because it was too low; or c)hit the number right on the head and owes nor is owed a penny.

Unfortunately for the IRS, it sent out some incorrect forms — how many, it’snot saying. “Only a small fraction of tax filers” it said in astatement. That depends upon whether you think the 800,000 peoplewho got the wrong form is a negligible number.

Some of those individuals may get the correct form prior toApril 15. The IRS is urging those people to file them.

For those who got the wrong form and don’t get the right one byApril 15, the IRS is offering an automatic extension, using Form4868. For those who haven't yet been sent corrected taxforms, they now have until Oct. 15 to file, as long as they requestan extension.

Eventually, they will receive the proper form, the IRS promised.“When taxpayers receive their Form 1095-A, they should file theirreturn using the information from the form. Treasury and IRSintend to release guidance shortly implementing penalty relief forindividuals in this situation as long as they file a return byOctober 15.”
