WASHINGTON (AP) — Filing a federal tax return is about to get more complicated for millions of families because of President Barack Obama’s health law. But they shouldn’t expect much help from the Internal Revenue Service.

Got a question for the IRS? Good luck reaching someone by phone. The tax agency says only half of the 100 million people expected to call this year will be able to reach a person.

By Avik Roy On March 4, the Supreme Court will hear oral arguments in King v. Burwell, the case that many pundits claim will “blow up Obamacare.” That’s an exaggeration; whatever the High Court decides, Obamacare will remain entrenched in federal law. But if the Supremes do end up ruling against the Obama administration—a distinct possibility—they will be giving Congress a uniquely important opportunity to reshape the Affordable Care Act in far-reaching ways. Here’s how that could work.

On Friday, I posted this chart, showing that nearly all the job growth since the recession ended has been in full-time jobs. Part-time employment is pretty much flat.

I wasn’t trying to make a political point, but many readers saw one anyway. Specifically, they saw it as a refutation of a frequent Republican talking point: that the Affordable Care Act, or “Obamacare,” is killing full-time jobs because it requires employers to offer health insurance to their full-time (but not their part-time) workers.

Deluged with catastrophes, court challenges and criticism, Obamacare (ACA) has had a controversial life to date. Yet it is ready to enter a completely new phase where the implementation gets shifted to the Internal Revenue Service – America’s favorite three words. If you liked the health care plan up to now, you ain’t seen nothing yet.

WASHINGTON — If you’re among the millions of consumers who got financial help for health insurance last year under President Barack Obama’s law, better keep an eye on your mailbox.

The administration said Monday it has started sending out tax reporting forms that you’ll need to fill out your 2014 return. Like W-2s for health care, they’re for people who got health insurance tax credits provided under the law.
