Frequently Asked Questions

What are NTEE categories?

NTEE (National Taxonomy of Exempt Entities) is the classification system used by the IRS to categorize nonprofits into 26 major groups such as Health, Education, Human Services, and Arts. Each category has subcategories for more specific classification.

How are nonprofits classified?

Nonprofits are assigned NTEE codes by the IRS based on their stated mission and activities. These codes determine which category they appear under. Some organizations may be reclassified over time as their missions evolve.

Which category has the most revenue?

Health (NTEE E) dominates with $1.81 trillion in revenue — 44% of all nonprofit revenue — despite having only about 45,000 organizations. This is driven by large hospital systems and health plans.

Why are so many nonprofits 'Unclassified'?

Nearly 583,000 nonprofits lack proper NTEE classification (category Z), generating $768 billion in revenue. This is a known data quality issue — many smaller or newer organizations have not been assigned specific codes by the IRS.
