WASHINGTON --The Internal Revenue Service has released a draft version of the form that small businesses and tax-exempt organizations will use to calculate the small business healthcare tax credit. The form will be used when income tax returns are filed in 2011. The IRS also announced how eligible tax-exempt organizations can claim the credit during next year's filing season.

Tax-exempt organizations will utilize Form 990-T, which is used to report and pay tax on unrelated business income, even if they do not owe taxes. The final version of the form will be released later this year.

In 2010, the credit is generally available to small employers that contribute an amount equivalent to at least half the cost of single coverage towards buying health insurance for their employees. Until 2013, the maximum credit is 35 percent of premiums paid by eligible small business employers and 25 percent of premiums paid by eligible employers that are tax-exempt organizations.
