Lists Largest by total revenue
Largest nonprofits in Washington by total revenue
Organizations whose address on record is in Washington, ranked by the total revenue on each one's most recent Form 990, 990-EZ or 990-PF that reports it, as filed. Tax years differ from row to row: each is that organization's latest such return. An amended return is counted once, replaced by its amendment.
Not every nonprofit can appear. Churches and most religious congregations are not required to file a 990, and organizations with gross receipts normally under $50,000 file the 990-N postcard, which reports no revenue.
