Open enrollment for Obamacare’s second year begins in two months. Recent reports suggest that this year’s enrollment period will not be a smooth process.

According to Ricardo Alonso-Zaldivar of the Associated Press, individuals face many hurdles in signing up for or renewing coverage:

• For the roughly 8 million people who signed up this year, the administration has set up automatic renewal. But consumers who go that route may regret it. They risk sticker shock by missing out on lower-premium options. And they could get stuck with an outdated and possibly incorrect government subsidy. Automatic renewal should be a last resort, consumer advocates say.

• An additional 5 million people or so will be signing up for the first time on HealthCare.gov and state exchange websites. But the Nov. 15-Feb. 15 open enrollment season will be half as long the 2013-2014 sign-up period, and it overlaps with the holiday season.

• Of those enrolled this year, the overwhelming majority received tax credits to help pay their premiums. Because those subsidies are tied to income, those 6.7 million consumers will have to file new forms with their 2014 tax returns to prove they got the right amount. Too much subsidy and their tax refunds will be reduced. Too little, and the government owes them.

• Tens of millions of people who remained uninsured this year face tax penalties for the first time, unless they can secure an exemption.

These won’t be the only issues. In July, the Government Accountability Office told Congress that the HealthCare.gov website is still not complete. The back-end system that links the website to insurers and distributes the subsidies is not operational. Additionally, thousands, possibly millions, of insurance policies will be cancelled over the next several months for not including all of Obamacare’s mandates which will increase the confusion for individuals.

The Obama administration says that this year’s open enrollment period will be better than the last, but the complexity and short enrollment period will still create lots of headaches for consumers. Shockingly, overhauling a large swath of the United States economy is not easy work.
