Compare a nonprofit tax return with its narrative, reporting period and related records. Use a worksheet that avoids misleading expense comparisons.
A Form 990 can help you examine a nonprofit's reported activities, finances and governance for a particular tax year. It is a dated organizational disclosure, not a live account balance or a complete evaluation of impact. Start by identifying the organization, its employer identification number and the form it actually filed.
Use the IRS Tax Exempt Organization Search and the organization's own disclosures. Different organizations may file Form 990, 990-EZ, 990-PF or other applicable returns or notices. Do not compare their line numbers as though the forms were interchangeable.
The IRS Form 990 instructions explain the form's sections and schedules. For a full Form 990, program descriptions, compensation, functional expenses and the balance sheet live in different parts. Read relevant explanations and schedules alongside the headline figures.
Use this comparison sheet:
| Field | What to establish |
|---|---|
| Organization and EIN | Confirm the entity, including related entities |
| Form and tax year | Match the correct instructions and period |
| Original or amended | Identify the version used |
| Program narrative | What activity does the organization report? |
| Financial field | Record the exact part, line and definition |
| Comparison basis | Check years, accounting changes and entity boundaries |
| External evidence | Seek program records, audited statements or interviews |
Filing and publication lag mean an available return may describe an earlier operating period. Put that period beside every figure. For a private foundation's return, use the separate Form 990-PF instructions, not a remembered Form 990 map.
Imagine a hypothetical nonprofit whose reported program expenses increase while the number of people served falls. That comparison raises a question. It does not prove waste: the program, eligibility, service intensity or counting method may have changed.
Check the narrative, prior return, related schedules and other public financial statements. Ask the organization to explain the comparison and request the basis for its outcome measures. Interview people with relevant knowledge of the service. Attribute explanations and identify which you could independently check.
Likewise, a single compensation figure or overhead ratio cannot establish whether an organization is effective. Explain the context and the limits of the measure instead of presenting an intuitive ranking as an audited conclusion.
Show the relevant years, entity names and source locations. Separate what the return reports from what your other reporting establishes. Include material responses and unresolved questions. Keep the files in a standing record so the next filing can extend the comparison without silently changing its basis.
