Which organizations are required to attach a Schedule E with the Form 990-EZ?

Schedule E must be used by organizations that file IRS Form 990-EZ to report information on private schools. 
 
You have to answer 'Yes' to Line 48 of Part VI in Form 990-EZ if your organization is a school and attach a Schedule E along with your Form 990-EZ.
 
The organization that attaches a Schedule E will also have to attach a Schedule A along with its annual information return because a school will be considered as a public charity status and public support.
 
Schedule E along with Schedule A will be generated automatically while filing your Form 990-EZ using the 'Interview-Based' filing in Tax990. Both Schedule A and Schedule E will be made available to you depending upon the information you enter in your Form 990-EZ using the 'Form-Based' filing in Tax990.
