ReasonableCauseExplanation/ExplanationTxt0We are changing our fiscal year. We initially tried to timely file a form 990-N, but were unsuccessful because we couldn't get our new year end correctly into the software. We timely filed a Form 1128, but the IRS has not yet OK'ed the filing. We received a LTR 2645C stating that the IRS is still reviewing our request. We finally opted to file this 990-EZ to fulfill our obligation.
