🏦 Advanced Wealth Structuring & Family Office Governance
For UHNW clients, the operating entity is often a formalized family office. The required documentation shifts from basic business papers to comprehensive governance and regulatory compliance.
- Formal Governance Documentation: UHNW structures often involve multiple entities (trusts, LLCs, foundations). Essential documents include detailed family mission and values statements, investment policy statements (IPS) for each pool of capital, and formal family employment and loan policies to substantiate economic substance and avoid tax recharacterization. With increased IRS focus on UHNW taxpayers, strong governance documents are a new standard for compliance.
- Entity-Specific Compliance Records: To comply with the Corporate Transparency Act and global regulatory norms, you need: a beneficial ownership register for all legal entities; proof of filings for FinCEN, FBAR (FinCEN Form 114), and Form 8938 (Statement of Specified Foreign Financial Assets); and, for entities with foreign partners, a completed FATCA registration.
- Cross-Border & Treaty Documentation: For clients with assets or residency in multiple jurisdictions, document physical presence logs, professional advisory maps for each jurisdiction, and relevant tax treaty election forms (e.g., Form 8833) for U.S. clients claiming treaty benefits.
📜 Advanced Estate & Tax-Efficient Trust Planning
The standard trust documents are just the beginning. UHNW planning focuses on sophisticated vehicles to freeze or reduce estate values.
- Sophisticated Trust Instruments: Move beyond simple revocable trusts to include:
- Grantor Retained Annuity Trusts (GRATs), Spousal Lifetime Access Trusts (SLATs), Qualified Personal Residence Trusts (QPRTs), and Intentionally Defective Grantor Trusts (IDGTs).
- Completed funding checklists showing exactly which assets (business interests, real estate, life insurance) were transferred into these trusts.
- Crummey withdrawal power notices and records for annual exclusion gifts made to trusts.
- Allocation records for Generation-Skipping Transfer (GST) tax exemption (reported on Form 709), which is crucial for dynasty trusts.
- Estate Freeze & Closely Held Business Records: UHNW clients often own valuable, illiquid assets. For entities used in estate freezes (like Family Limited Partnerships (FLPs)), you must retain formal business purpose memos, annual valuation reports of transferred interests, and contribution & distribution records to support valuation discounts.
- Charitable & Split-Interest Structures: For sophisticated philanthropy, maintain the trust instrument for vehicles like Charitable Remainder Trusts (CRTs) and Charitable Lead Trusts (CLTs), alongside the Form 8283 for non-cash contributions and appraisal documentation.
✈️ High-Value Tangible & Lifestyle Assets
UHNW wealth often includes unique assets with significant tax, reporting, and insurance implications.
- Alternative & Complex Investments: These require specific K-1s and partnership agreements, but also subscription and side letter agreements for fund terms, valuation reports for illiquid assets, and loan/line of credit documentation for assets like private equity interests.
- Luxury Assets (Aircraft, Yachts, Art, Collectibles): Ownership is often through an SPV, requiring all formation and operating documents for those entities. Maintain complete purchase/sale and import documentation, operational logs (flight, navigation, and maintenance logs for aircraft; cruising logs for yachts), insurance policies, appraisals, and Form 1098 forms. Insurers’ records may be used to verify the value of these lifestyle assets.
📝 International & Specialized Compliance
- International Trust & Foundation Documentation: For offshore trust structures, you need the original trust deed, letter of wishes, resolutions, and proof of registration with local authorities. For non-grantor trusts, specific IRS forms are required: Form 3520-A (Annual Return of Foreign Trust with a U.S. Owner) and Form 3520 (for owners or beneficiaries receiving distributions). For non-U.S. situs trusts, retain IRD registration confirmation if relevant.
💎 Other Key Specialized Documents
- Tax Liability Management:
- Private Placement Life Insurance (PPLI) or Variable Annuities (PPVA): Policy documents, premium payment records, investment election forms, and loan documentation (e.g., split-dollar life insurance agreements).
- Net Investment Income Tax (NIIT) Planning: A complete breakdown of investment income by category, and a file of any passive activity loss carryover worksheets.
- Cancellation of Debt (COD): Documentation for any Form 1099-C received, along with insolvency worksheets or bankruptcy filings if exclusions are claimed.
- Family & Succession Planning:
- Pre-nuptial and post-nuptial agreements.
- Divorce decrees and separation agreements.
