2027 Nonprofit Good-Standing Calendar (Idaho): 990-N dates, SOS annual report and the 3-year rule

Small nonprofits rarely lose their tax-exempt status over anything dramatic. Usually a 990-N e-Postcard just slips for a few years while officers change. This calendar puts the dates in one place.

What's inside:

• 2027 990-N due dates for every fiscal year end, already moved for weekends and holidays (for example, a December 31 year-end is due Monday, May 17, 2027)
• Idaho Secretary of State annual report month-by-month table. Your report is due by the last day of your anniversary month.
• The three-year rule in plain English, with what happens on the third missed year
• A 12-month at-a-glance page you can print for the board binder
• A 10-minute yearly checklist: where to check your IRS and Idaho status, who needs a Login.gov or ID.me sign-in, and what to save
• A tracker spreadsheet for one or several organizations. Pick your months and the due dates fill in.

Good for: treasurers, board secretaries, booster clubs, PTOs, small clubs and associations, and anyone who inherited "the IRS thing" from the last officer.

Please note: this is educational information only, not tax or legal advice. The rules were checked against official IRS and Idaho sources in October 2026, and each page links to them. Always confirm on the official pages before filing. Trussline doesn't file anything for you and can't guarantee any outcome.
