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

- Feb 16, 2027: Form 990-N for FY2026. Fifteenth day of the fifth month after year end. February 15 is a legal holiday (Washington's Birthday), so the deadline moves to the next business day.
- Feb 15, 2028: Form 990-N for FY2027. Fifteenth day of the fifth month after year end.
- Annual: Colorado charitable solicitation registration. Charities that solicit in Colorado register with the state and renew each year, unless exempt. It is due by the 15th day of the fifth month after the fiscal year ends. An extension is available. For a fiscal year ending in September, that is February 15. Regulator: Charities Program, Colorado Secretary of State (https://www.coloradosos.gov/pubs/charities/charitableHome.html).
- Watch: Automatic revocation rule. No risk shown. Exempt status is revoked after three consecutive years without a return.

## No size comparison

No return with figures is on the IRS file, so there is nothing to compare.
