Compliance clock

What is due, and when

Computed from the fiscal year end and the return type. Federal dates are fixed by law. The state line is the general charitable solicitation rule of Michigan, read from the regulator’s own guidance; exemptions vary, and the regulator’s page is the authority.

Filing history

When each return reached the IRS

From IRS records of electronically filed returns. The IRS record date is the date in the IRS’s own record of each return. It is not a legal filing date, and extensions are not public.

Peers

No size comparison

Peer groups start at $50,000 of revenue on the latest return. Below that, most organizations file Form 990-N, which carries no financial figures, so there is no group to compare with.

Readiness

What public data cannot tell you

A 990 shows money in and money out. It cannot show whether programs, outcomes, funding and compliance live in one place, or how long a funder report takes to produce. The five pillars below are scored only by the organization itself.
