Everything here is what the organization told the IRS about itself. The IRS publishes returns as filed and does not audit them first.
The figures describe the most recent year on record, which is usually one to two years behind, and not the organization’s current position.
Nothing here says whether the organization does its work well, or how it spends what it raises beyond the totals on the form.
