Major tax law changes that would affect retirement plans probably won't take place in 2013, but the retirement community is watching regulators and the U.S. Department of Labor very closely.

Ed Ferrigno, vice president of Washington affairs for the Plan Sponsor Council of America, said that his organization is watching Congress' tax reform and deficit reduction discussions to make sure there aren't any provisions in them that would negatively impact retirement plans and plan sponsors.

"We got through the first round without any adverse impact, but President Obama and the Democrats have made it clear they are looking for additional revenue," he said.
