Annual Tax Returns

The Federal Employer Identification Number (FEIN) is a unique nine-digit number assigned by the IRS to business entities operating in the United States and is issued for the purpose of tax administration. All chapters must obtain an FEIN and follow IRS regulations regarding annual reporting.

Nearly all 501(c)(3) and 501(c)(6) organizations are subject to automatic revocation of their tax exempt status if they fail to file a required annual information return or notice for three consecutive years.

Which return form an organization must file depends on its financial activity as indicated by this chart:


Form to File

Gross receipts normally ≤ $50,000


Gross receipts < $200,000 and total assets < $500,000

990-EZ or 990

Gross receipts ≥ $200,000 or total assets ≥ $500,000


Private Foundation—regardless of financial status
