IRS Form 990 is required to be filed and publicly disclosed by nonprofits. It provides a useful look into an organization’s finances. The form changes some from year to year, so it can be confusing when making comparisons, but most of the same information is included each year, you just have to find it.
A couple of the files are split into two parts due to excessive size.
