Effective January 1, 2014, any organization with an Employer Identification Number (EIN), including tax exempt organizations, must notify the IRS of a change of address or the identity of a responsible party, using Form 8822-B. This form must be filed within 60 days of the change. If the change occurred before January 1, and has not been reported, you must file Form 8822-B before March 1, 2014. An updated Form 8822-B is available on IRS.gov. There is a box on the form that exempt organizations must check.
