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 Washington, read from the regulator’s own guidance; exemptions vary, and the regulator’s page is the authority.

Form 990 for FY2026 Not yet on the IRS file
The October 2026 IRS file shows FY2025 as the latest return. Filed on extension, it is due February 16, 2027.
Feb 16, 2027
Extended deadline for FY2026
Six month automatic extension (Form 8868). February 15 is a legal holiday (Washington's Birthday), so the deadline moves to the next business day.
Aug 16, 2027
Form 990 for FY2027
Fifteenth day of the fifth month after year end. August 15 falls on a Sunday, so the deadline moves to Monday.
Annual
Washington charitable solicitation registration
Charities that solicit in Washington register with the state and renew each year, unless exempt. It is due within eleven months after the fiscal year ends. The renewal must be received by the last business day of that month. For a fiscal year ending in March, that is the end of February.
Exempt status is revoked after three consecutive years without a return. The latest return on file is FY2025.
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.

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.
