WASHINGTON -- Many workers are getting false or misleading information about options for their 401(k) accounts when they change jobs, congressional auditors said Wednesday in a report that urged regulators to offer consumers clearer guidance about their retirement money.The Government Accountability Office found that financial firms often encourage workers to roll over a 401(k) into an individual retirement account, or IRA, even when that might not be the best option. The report said the guidance workers receive is either too complex or too general, leaving them vulnerable to financial firms that may try to steer them toward IRAs with higher fees."Labor regulations do not ensure that 401(k) plans provide complete and timely information to participants on all their distribution options," the report said.Workers changing jobs can also leave retirement funds in the previous employer's plan, move them to a new employer's 401(k) or cash them out and incur hefty taxes.GAO undercover investigators contacted 30 firms and reported that seven incorrectly said that their IRA was free or that there were no fees to open or maintain an IRA. The report also said five of the 10 websites reviewed by the GAO claimed their IRAs were free. Fee information on the sites was hard to find and understand, the report found.Democratic lawmakers say the report shows a need for stronger consumer protections in the growing 401(k) rollover market. The lawmakers -- Sen. Tom Harkin, D-Iowa, Sen. Bill Nelson, D-Fla., and Rep. George Miller, D-Calif. -- called on the Obama administration to modify rules to protect consumers from receiving advice that could be biased."Service providers should not be permitted to provide incomplete information or steer workers to company investment products," the lawmakers said in a letter to the Labor and Treasury departments.The Investment Company Institute, a trade association for mutual fund companies, said financial company affiliates managing employer retirement plans already offer workers "full information.""The mutual fund industry supports these efforts and clear disclosure of all fees and expenses in connection with any rollover of assets from a 401(k) plan to an IRA," ICI spokeswoman Rachel McTague said.
