No. 5: Get your health insurance tax credits for this year and past years.

Health insurance tax credits are one of the biggest missed opportunities for small businesses. These tax credits began in 2010. You may apply for credit retroactively. Starting in 2014, the tax credit covers up to 50 percent of employer-paid premium costs for taxable organizations or 35 percent for tax-exempt organizations. Visit the IRS small-business health insurance tax site for more information.
