What is Form 990?
Form 990 is the IRS tax return for tax-exempt organizations. It shows:
-
Income
-
Expenses
-
Governance and leadership information
Filing Form 990 keeps your nonprofit in good standing and builds trust with donors. Without it, your nonprofit risks fines or losing tax-exempt status.
Pro Tip: Even small nonprofits should track finances carefully. Accurate records make filing Form 990 much easier.

Who Must File Form 990?
Not all nonprofits file the same form. Here’s who must file:
-
Large nonprofits: Gross receipts over $200,000 or assets over $500,000 file the standard Form 990.
-
Smaller nonprofits: Gross receipts under $200,000 may file Form 990-EZ.
-
Very small nonprofits: Gross receipts under $50,000 may file Form 990-N (also called the e-Postcard).
-
Churches: Usually exempt but check for special circumstances.
Pro Tip: Filing the correct form keeps you compliant and avoids unnecessary IRS questions.

990-EZ vs 990-N
Here’s a simple comparison:
Form | Who Files | Details | How to File |
|---|---|---|---|
990 | Large nonprofits: Gross receipts over $200,000 or assets over $500,000 | Long form | Online |
990-N | Very small nonprofits (under $50k revenue) | Tiny, online-only e-Postcard | Online via IRS website |
990-EZ | Small nonprofits (under $200k revenue) | Shorter than full 990, reports basic finances | Online |
Pro Tip: Even if your nonprofit qualifies for 990-N, maintaining full records is smart. It helps with audits, grants, and growth.

Filing Deadlines
Most nonprofits must file Form 990 5 months after fiscal year-end.
-
Example: Fiscal year ends Dec 31 → Deadline is May 15.
-
Late filings may trigger penalties.
Tip: File early if possible. Late filings can cause fines or revoked tax-exempt status.
Penalties for Late Filing
The IRS can fine nonprofits that file late:
-
$20 per day for small nonprofits (<$1M revenue)
-
$100 per day for larger nonprofits (> $1M revenue)
-
Maximum penalties can reach the total revenue of the organization in severe cases.
Repeated late filings may automatically revoke tax-exempt status.
Tip: Even if funds are tight, file on time. It protects your nonprofit’s credibility and status.
Nonprofit Bookkeeping Requirements
Proper bookkeeping makes Form 990 easy. Here’s what you need:
-
Track all income (donations, grants, fundraising).
-
Track all expenses (program costs, administrative costs).
-
Separate restricted funds from unrestricted funds.
-
Keep detailed donor records for acknowledgments and compliance.
-
Use nonprofit-friendly software like QuickBooks Setup Services.
Pro Tip: Consistent bookkeeping prevents headaches when filing Form 990 or preparing for audits.
