The Annual Cycle

The Calendar That Runs the Organisation

A nonprofit's fiscal year can end on any month's last day, but the choice is not trivial. Most organisations follow a December 31 close, aligning with the calendar year; others pick June 30 or September 30 to match grant cycles or to spread accounting work away from year-end crunch. Whatever the date, it starts a chain.

The Form 990 is due on the fifteenth day of the fifth month after the fiscal year closes. A December 31 close means a May 15 deadline; a June 30 close means November 15. Miss that date without requesting an extension and penalties accrue — currently $20 per day for smaller organisations, $100 per day for those with gross receipts above $1 million, under Internal Revenue Code section 6652(c) ↗.

One automatic six-month extension is available by filing Form 8868 before the original deadline. That is the outer limit; there is no second extension. An organisation on a December 31 cycle that files Form 8868 on time buys itself until November 15. The extension applies to filing, not to payment of any tax owed — unrelated business income tax, for instance, is still due on the original deadline.

Three consecutive years of failing to file — whether the full 990, the 990-EZ, or even the 990-N e-postcard for small organisations — triggers automatic revocation of exempt status. The IRS publishes the list of revoked organisations, and reinstatement requires a new application and, in most cases, a retroactive filing of the missed returns.

Larger organisations face an additional rhythm: the independent audit. The threshold for audit requirements varies by state — some set it at $500,000 in gross revenue, others higher — and many grant funders impose their own audit requirements regardless of state law. The National Association of State Charity Officials ↗ maintains a summary of state-level thresholds. An audit finished well after the fiscal year close can delay the 990, making the extension almost routine rather than exceptional.

Internally, the cycle shapes board work too. Finance committee review of draft financials, board approval of the 990 before filing, and review of the auditor's management letter all need agenda time in the months following year-end. The calendar is not administrative background noise — it is a structural frame around which governance actually runs.
