NEW YORK – Rose Wang looks at her staff of 70 employees and wonders if she'll have to lay off some of them to comply with the health-care law.

The owner of Binary Group Inc., an information technology firm based in Alexandria, Va., is one of many small business owners who will be required to provide health insurance for her staffers under a provision of the law that goes into effect on Jan. 1, 2014. Wang already provides insurance, but she has struggled with premiums that have soared as much as 60 percent annually, so she requires employees to contribute to their coverage. She's worried because she doesn't know how much she'll have to pay under the Affordable Care Act.

Wang's worry is a gut-wrenching dilemma that many small business owners are concerned that they may face. Now that President Barack Obama has won re-election, the health-care overhaul, which presidential candidate Mitt Romney promised to dismantle, is marching forward. Companies must decide before the start of 2014 what they'll do to comply with the law. Right now, no one knows how much the insurance will cost, and owners aren't sure if they'd be better off not buying it and paying a government a penalty of $2,000 per worker. Some owners are even threatening to defy the law. The big challenge for most small businesses is that they just don't have enough information to make concrete plans.
