Private foundations face a compliance minefield: Form 990-PF filings, excise tax calculations, grant-making documentation, and state regulatory requirements all demand precision. If you're offering services to foundation boards and administrators, a tiered tax compliance package strategy separates you from generic accountants and positions you as a specialist. Here's what to build and sell.
The Foundation Compliance Landscape
Private foundations operate under stricter IRS rules than public charities. A single mistake on Form 990-PF—the annual tax return for private foundations—can trigger penalties, audit triggers, or worse, jeopardize the foundation's tax-exempt status. Foundation managers are increasingly willing to pay premium fees for specialists who understand the nuances of excise taxes on net investment income, related-party transactions, and state-level filing requirements that vary wildly by jurisdiction.
This is where your expertise becomes sellable. A foundation with $5 million in assets and an annual payout obligation isn't shopping around for budget pricing; they're shopping for accuracy and peace of mind.
Package Tier 1: Core Compliance ($2,500–$4,500/year)
Start with the bread-and-butter offering. This tier handles:
- Preparation and filing of Form 990-PF
- Calculation of the 1.39% federal excise tax on net investment income
- Basic grant-making documentation review
- State charitable registration renewal and filing (where applicable)
- Preliminary year-end planning memo identifying upcoming deadlines
Target this package at foundations with assets under $10 million and simple grant-making structures. Price it at a fixed annual retainer so foundations budget predictably. Bundling removes the hourly-rate anxiety that makes foundation boards hesitant to call with questions.
Package Tier 2: Enhanced Governance & Planning ($5,500–$8,500/year)
Step up to attract growing foundations or those facing complexity. Include everything in Tier 1, plus:
- Quarterly tax compliance checklists (what to save, what triggers filing requirements)
- Related-party transaction review and documentation
- Grant-making policy audit (ensuring distributions meet minimum payout requirements)
- Real estate or alternative asset valuation coordination
- Annual board memo summarizing tax law changes affecting the foundation
This tier appeals to family offices and mid-size foundations ($10–$50 million in assets) that want someone actively managing compliance risk rather than just filing forms after the fact.
Package Tier 3: Full Tax & Strategic Advisory ($12,000–$20,000+/year)
Build your premium offering for foundations with complex structures, multiple trusts, or substantial real estate holdings. Include all prior tiers, plus:
- Proactive excise tax optimization strategies
- Donor-advised fund coordination (if the foundation partners with DAFs)
- International grant-making compliance review
- Succession planning for foundation leadership
- Monthly or quarterly advisor-on-call access (8 hours/quarter, typically)
- Custom grant-making policy development aligned with IRS expectations
This tier also works for foundations considering major structural changes—merger, grant conversion, or closing—where you bill hourly above the retainer for project work.
What to Actually Deliver
Don't just list what you're offering. Specificity wins deals. Your proposal should spell out:
Timeline clarity: "Form 990-PF is filed by May 15. We'll deliver draft financials to your accountant by April 1, request your final grant list by April 10, and file by May 1."
What you need from them: Create a one-page checklist of documents and info you need (year-end valuations, grant payment records, new investments, trustee changes). Send it in January before the rush.
Deliverables in writing: "You'll receive three documents: the filed 990-PF, a summary memo explaining changes from prior year, and a compliance checklist for next year."
Red flags you'll monitor: "We flag any grant to related parties, grants over $50,000 to single recipient, and distributions below minimum payout before filing."

Frequently Asked Questions
Q: What's the difference between my package and just hiring a CPA to file 990-PF? A: Your package includes proactive compliance planning, not just form filing. A generalist CPA processes what you give them; you're identifying risks and opportunities throughout the year, saving the foundation money on excise taxes and avoiding audit exposure.
Q: Do I need different expertise for donor-advised funds versus private foundations? A: Yes—DAF sponsors and private foundations face different compliance rules, and some foundations coordinate with DAFs for strategic giving. You'll need specific knowledge of DAF contribution documentation and distribution tracking if you're offering this tier.
Q: How much should I charge per hour if a foundation asks for work outside my package? A: $200–$350/hour is market-standard for foundation tax specialists, depending on your location and experience. Scope overages clearly to avoid margin erosion.
