Don’t forget that May 15 is the filing deadline for calendar year tax exempt organizations. Get that Form 990 (series) filed by that date, or get your extension in by then to secure three months of additional filing time.
Sometimes, very small exempt organizations fail to file at all, due usually to lack of familiarity with the rules by their typically hard-working key people, and not due to any intentional malfeasance. Check your organization’s status – failure to file for three consecutive years can result in automatic revocation of tax exempt status!
And if you are up to date on your filings, also be sure to accomplish the usual public disclosure which most exempt organizations must do.
