More tax breaks to encourage small businesses to offer employees retirement plans are unlikely, House Small Business Committee Chairman Sam Graves (R-Mo.) told Financial Advisor magazine Wednesday.

That suggestion was one way Congress could increase the share of small businesses offering retirement benefits from 14 percent, Transamerica Center for Retirement Studies President Catherine Collison told a committee session Wednesday.

However, Graves said the focus of Congress on tax legislation is in a wholesale rewriting of the tax code rather than considering piecemeal measures.

Collison contended during her testimony that the minimum default contribution rate in defined contribution plans gives a false sense of security to employees that they are putting away enough for a comfortable retirement. She advocated raising the default to 8 percent and then 10 percent to decrease the likelihood workers will outlive their savings.

The Transamerica Center leader and Small Business Council of America Representative Paula Calimafde said more small businesses would offer retirement plans if they were not held to a fiduciary responsibility for the benefits.

Republican House Member Richard Hanna of New York was the only Congressman on the committee voicing objection to the idea, noting every day the IRS goes after small employers who have stolen their employees’ Social Security deductions.

During the shutdown, some House and Senate committees have gone on with their previously announced sessions while others have canceled them.
