Filing Signals

Signals are automatically computed flags derived from each organization's own public IRS filings across all available years. They are the starting point for a question — not the end of one. Signals help practitioners decide where to look — not what to conclude.

Plain-language definition

If you only read one box on this page, read this one: a Filing Signal is a prompt to look closer at a change in an organization's own filings over time. It is not a verdict, not a warning label, and not evidence of wrongdoing. It helps a practitioner decide which question to ask next.

What signals are

A signal appears when Harbor Commons detects a notable pattern in an organization's own filing history: a revenue swing, a structural change in expense mix, an unusual disclosure, a shift in program activity. Signals are longitudinal — they compare an organization to its own prior filings, not to peer organizations or external standards.

A Filing Signal is a computed pattern flag based on the organization's own historical filings. It can help a treasurer, commodore, executive director, or board member spot where context may be needed before a meeting, budget discussion, or comparison with peers.

What signals are not:

  • IRS audit flags
  • Compliance violations
  • Legal findings
  • Accusations of any kind

They're prompts to look closer — not conclusions.

The people best positioned to interpret a signal are the people inside the organization. Context lives with the practitioner.

Example: a high net revenue year could indicate great operational performance, or it could mean turnover, downsizing/right-sizing, or a deferred mortgage payment. It can be good, neutral, or bad — and unless you're internal to those meetings, numbers, and context, you don't know why. The filing shows the movement; people with operational context explain the reason.

Financial signals

Financial signals point to changes in the money picture reported on an organization's filings: revenue, expenses, assets, and related patterns. They help readers separate normal variance from years that deserve a closer second look.

Some financial signals are capacity signals — they look for mismatches between growth (revenue or program activity) and the resources required to carry that work (labor cost and headcount). These signals can reflect intentional strategy (outsourcing, automation, seasonality, or staffing-mix shifts) as well as operational pressure. Capacity signals are prompts to ask better questions, never claims about management quality or intent.

  • Revenue and expense mix shifts relative to prior years.
  • Deficit patterns sustained across multiple filings.
  • Reliance concentration — e.g., an org where one event generates 90%+ of annual revenue.
  • Year-over-year changes in net assets.

Governance signals

Governance signals point to disclosures about leadership structure, related-party activity, or compensation patterns. They can help boards and staff identify where additional context or documentation may be useful.

  • Related-party transaction disclosures (Schedule L).
  • Board independence composition where the filing warrants a closer look.
  • Unusual officer compensation structures.
  • Concentration risk in key-person disclosures.

Operational signals

Operational signals point to changes in how the organization describes its programs, timing, or filing structure. They can reveal mission shifts, seasonality effects, or administrative changes that shape how a filing should be read.

  • Program description changes across years.
  • Additions or removals of major programs.
  • Filing timeline irregularities.
  • Structural changes — e.g., a shift from Form 990 to Form 990-EZ.

What signals cannot do

Signals cannot explain context the filing doesn't carry: a pandemic year, a capital campaign, a leadership transition, a merger. Signals cannot distinguish intentional strategy from oversight. Signals cannot read intent.

Operationally, this means Signals are best used to prepare for a conversation, not to end one. They help someone walk into a finance or board discussion with a sharper question, not with a final answer.

If a signal misrepresents your organization's situation, tell us. That context makes the instrument more accurate for every practitioner who looks at it after you. Send us a signal →
