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 Maine, 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.
