Five Retirement Plan Options for Your Business From IRAs to profit-sharing plans, learn which option is best to consider for your company's future.

Owners of small and midsize businesses don't save enough for retirement. A March 2010 report released by the SBA found that only 36 percent have an IRA, and only one-third of those contributed to it. Less than 20 percent participate in 401(k) plans.

Finding the right plan can be confusing, "especially if the business changes or grows," says David Boucher, senior vice president of corporate benefit services at Longfellow Benefits, an insurance brokerage and consulting firm in Boston. But something is better than nothing. Use our chart below to get familiar with the options.

SEP-IRAs
Suggested for: Businesses with no employees

Contribution thresholds: Up to 25 percent of up to $245,000 or $49,000 for 2010 and 2011
