“The organization is organized as a non-stock corporation with a board of directors instead of members or stockholders.”
“The organization is organized as a non-stock corporation with a board of directors instead of members or stockholders.”
“Copies of form 990 are provided to the organization's governing body for their review before the form is filed.”
“Directors, officers and council members are required to fully disclose the nature of the interest and withdraw from discussion. Meeting minutes record such disclosures and abstentions.”

“Western massachusetts regional library systems is a part of a consolidated financial statement included in the massachusetts library system. This organization has been winding down and was trying to sell its only asset as of the year end of this tax return. In october 2015 the western massachusetts regional library system sold its only asset and is working to pay off the remaining mortgage. They do not pass the public support test, on an individual basis, but they are not a private foundation as they will be closing down for the 2015 tax return filing. On a consolidated basis they do pass the public support test.”
“No change in audit procedure.”
“The agency is recognized as an organization exempt from federal income taxes under section 501(c)(3) of the internal revenue code (the "code") whereby only unrelated business income, as defined by section 512(a)(1) of the code, is subject to federal income tax. In addition, the agency has been determined by the internal revenue service not to be a private foundation within the meaning of section 509(a) of the code. The agency recognizes and measures its unrecognized tax positions in accordance with fasb asc 740, income taxes. Under that guidance the agency assesses the likelihood, based on their technical merit, that tax positions will be sustained upon examination based on the facts, circumstances and information available at the end of each period. The measurement of unrecognized tax positions is adjusted when new information is available, or when an event occurs that requires a change. Interest and penalties associated with unrecognized tax positions are classified as additional income taxes in the combined statement of activities. The agency did not identify any uncertain tax positions in 2015 or 2014. The agency is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress.”
