Short answer
What this page answers
MMVFO supports advisor teams with specialty tax diagnostics, R&D credit files, international reporting, controversy triage, tax strategy second opinions, and family-office tax coordination under written scope and professional-boundary review.
Advisor co-advisory
Advisor coordination network
Advisor support is structured around written scope, client authorization, professional boundaries, and clear deliverables.
Who this is for
- CPA firms needing specialty tax support
- RIAs with founder, liquidity, or family office clients
- Attorneys needing tax strategy or evidence support
- Insurance professionals coordinating estate or business-owner risk
- Advisors who need client-authorized specialty tax support with defined scope and clear disclosures
Common problems
- Specialty tax work falls outside the advisor's normal service scope.
- R&D, international forms, controversy, or complex planning issues need deeper support.
- Client deliverables need to be technically credible without displacing the primary advisor.
- Referral relationships lack a clear intake, confidentiality, client-consent, and compensation framework.
- Advisors need a credible technical layer without confusing licensing, privilege, or professional-rule boundaries.
How MMVFO helps
- Offer a specialty tax desk for strategy, R&D, international, compliance, and controversy matters.
- Support referral, co-advisory, co-branded, or advisor-led diagnostics where engagement terms and professional rules allow.
- Use MMVFO Diagnostics for matter triage, classification, document organization, and expert review workflows.
- Document scope, referral compensation, licensing boundaries, and client ownership clearly.
We support your clients without displacing you.
MMVFO’s advisory model is built on the same principle we apply to client relationships: engagements are structured to support the referring or coordinating firm, not to expand into the broader client relationship.
When a CPA firm, RIA, attorney, family office, or other advisor brings MMVFO in for R&D credit work, international tax, controversy triage, compliance support, or tax strategy review, the engagement begins and ends with the specialty scope documented in writing. The primary client relationship remains with the referring or coordinating firm unless the parties agree otherwise under appropriate disclosure and engagement terms.
Partner engagement modes
Referral-only support
The advisor introduces MMVFO for a defined specialty matter with written scope, disclosure, and client consent where required.
Shared client support
MMVFO works alongside the primary advisor on diagnostics, client meetings, documentation, and execution planning.
Advisor-led delivery where permitted
Advisor-led or co-branded delivery can be considered only where professional rules, disclosures, client authorization, and engagement terms allow.

R&D Co-Advisory for CPA Firms That Need Defensible Credit Files
CPA firms do not need to build a full specialty R&D practice to serve clients well. MMVFO works as a technical co-advisor, referral partner, or client-authorized support resource for Section 41 credit studies, documentation, Form 6765 workpapers, and examination-readiness files.

International Tax Support for Advisors With Cross-Border Clients
Advisors often discover international exposure after a client has formed a foreign entity, inherited an account, bought foreign funds, or received a penalty notice. MMVFO provides a behind-the-scenes international triage layer.

Coordination and compliance posture
Each engagement is scoped in writing. MMVFO coordinates strategy, diagnostics, documentation, and advisory execution; it does not provide insurance implementation, investment advisory services, financial planning, securities-related services, legal services, or other regulated services unless that scope is expressly handled by a properly licensed or registered affiliate, professional, or the client’s existing advisor under appropriate written terms.
