It’s crunch time for thousands of small business owners who must comply with requirements of the health care law for the first time.

Companies with 50 to 99 full-time employees must offer affordable insurance to employees and their dependents starting Jan. 1. They must also file tax forms with the government by Jan. 31 detailing the cost of their coverage and the names and Social Security numbers of employees and their dependents. While companies of all sizes are subject to the law must file the forms, smaller businesses without big staffs to handle the paperwork may have to hire someone to do it — at a cost of hundreds or thousands of dollars.
