Nonprofits that ignore audit and Form 990 requirements don't just face IRS penalties — they risk losing tax-exempt status entirely. If you offer audit or Form 990 services, your clients are counting on you to keep them compliant, and understanding the full landscape helps you sell your expertise more effectively.
Who Must File Form 990 and When
The IRS requires most tax-exempt organizations to file an annual information return. Which version they file depends on gross receipts and total assets:
- Form 990-N (e-Postcard): Gross receipts normally ≤ $50,000
- Form 990-EZ: Gross receipts < $200,000 and total assets < $500,000
- Form 990: Gross receipts ≥ $200,000 or total assets ≥ $500,000
- Form 990-PF: Private foundations regardless of size
The filing deadline is the 15th day of the 5th month after the fiscal year ends — typically May 15 for calendar-year organizations. A six-month extension (Form 8868) is available, but it's an extension to file, not to pay any taxes owed.
Missing three consecutive years of filing triggers automatic revocation of tax-exempt status. That's the kind of outcome your clients hire you to prevent.
When Is a Nonprofit Audit Actually Required?
Not every nonprofit needs an independent financial audit, but the triggers are more common than many organizations realize. Here's what typically requires one:
- Federal expenditures: Organizations spending $750,000 or more in federal awards in a single year must undergo a Single Audit under the Uniform Guidance (2 CFR Part 200)
- State law requirements: Many states have their own thresholds — California requires an audit at $2 million in gross revenue, New York at $1 million, and Illinois at $300,000
- Grant requirements: Major foundations and government funders routinely require audited financials as a grant condition
- Board or bylaw requirements: Some nonprofits require audits in their governing documents regardless of size
If you work with nonprofits in multiple states, knowing each state's charitable solicitation registration and audit threshold is a genuine competitive advantage you can market directly.
The Form 990 Compliance Checklist Your Clients Need
Form 990 is far more than a tax return — it's a public document that donors, watchdog organizations, and grantmakers review before giving. Part of your value as a service provider is helping clients understand what that means.
Walk through these key areas with every client:
- Part IV – Checklist of Required Schedules: Triggers additional schedules (A through R) based on activities. Missing a required schedule is one of the most common errors.
- Part VI – Governance, Management, and Disclosure: Asks about conflict-of-interest policies, whistleblower policies, and document retention policies. Many small nonprofits lack written policies.
- Part VII – Compensation: Officers, directors, key employees, and highest-compensated employees must be disclosed if compensation exceeds $100,000.
- Part IX – Statement of Functional Expenses: Requires allocating expenses across program services, management, and fundraising — often a significant work product.
- Schedule B: Lists substantial contributors. Frequently mishandled and subject to IRS scrutiny.
- Related party transactions: Disclosed in Schedule L; common in family-run foundations and small nonprofits.
Providing a structured review of these areas — not just preparing the return — is what separates commodity 990 preparers from trusted advisors clients retain year after year.
Pricing and Scope Considerations for Your Practice
Being transparent about pricing builds trust and filters out mismatched clients. Rough market ranges for Form 990 services:
- 990-EZ preparation: $500–$1,500
- Full Form 990: $1,500–$5,000+ depending on complexity, number of schedules, and revenue size
- Nonprofit financial audit (compiled or reviewed statements): $3,000–$8,000 for smaller organizations
- Single Audit: $10,000–$25,000+ for organizations with significant federal funding
Recurring engagements — audit plus 990 preparation bundled annually — are the highest-value arrangements. Offer a multi-year engagement discount to lock in clients and reduce your own administrative friction.
Getting Found by Nonprofits That Need You
Nonprofits actively search for specialized audit and 990 preparers, but they often don't know where to look. Listing your firm on a marketplace or directory like Mercoly helps you get found by those clients, generate qualified leads, and clearly present your services and pricing in one place.
Beyond directories, consider publishing state-specific compliance guides, speaking at nonprofit association events, and building referral relationships with nonprofit attorneys and consultants who work in your region.
The nonprofits that need you most are often the ones too small to have in-house financial staff — they need a trusted outside expert, and they're willing to pay for that relationship.
Add your firm to a nonprofit-focused directory today and start connecting with organizations that are actively looking for exactly the services you provide.
