The number of small-business owners offering retirement savings plans for their employees has jumped considerably in the past year, with 24 percent of small businesses now offering a 401(k) plan compared to only 10 percent in 2008.

A nationwide survey by ShareBuilder 401k also found that the majority of small-business owners, 58 percent, believe their current retirement savings is higher than it was five years ago.

The survey, conducted in June, revealed a significant shift in 401(k) planning and investing when compared to a similar survey conducted in 2008, including: 65 percent of those questioned now feel confident they're saving enough for retirement, compared to 44 percent five years ago; 82 percent of all small-business owners view 401(k)s as an effective approach to saving for retirement; of the 28 percent of businesses with a 401(k) plan that either stopped offering a match or lowered their match over the past five years, 56 percent have since reinstated it.
