Organizations with less than $200,000 in gross revenue and assets under $500,000 qualify to file Form 990-EZ. The IRS also refers to 990-EZ as the Short Form return.
For example, an organization may have $35,000 in gross revenue, which means it qualifies for the 990-N filing. However, say the organization owns the building where it conducts operations, and its value is $300,000. Because of the significant asset the origination owns, it must file the 990-EZ instead of the 990-N.
