Family offices function as centralized wealth management centers for high-net-worth families, seamlessly coordinating tax planning, investment oversight, estate structuring, and philanthropic initiatives to protect and grow substantial assets over multiple generations.
The One Big Beautiful Bill Act, signed into law in July 2025, fundamentally enhances this role by making most Tax Cuts and Jobs Act provisions permanent, including lower individual rates and the 23% qualified business income deduction, while raising the estate and gift tax exemption to a permanent $15 million per individual ($30 million for couples) starting in 2026 and indexed for inflation thereafter.
Additional features like temporary no-tax treatment for certain tips and overtime through 2028, along with expanded Qualified Small Business Stock benefits, create fresh opportunities amid heightened IRS scrutiny on HNW entities. More than 60% of affluent clients now demand holistic tax integration, and family offices excel at delivering it, routinely generating $100K to $500K or more in annual savings through targeted deductions and robust compliance.
At Squires Tax Planning, our partnerships with family offices have ethically preserved millions for clients by navigating these rules expertly. Below, we detail five key strategies family offices employ to maximize tax efficiency in 2026.
Deduct Operating Costs as Business Expenses Under IRC §162
When structured as an active trade or business, as validated in Lender Management v. Commissioner (T.C. Memo. 2017-246), a family office can fully deduct ordinary and necessary expenses like advisory fees, salaries, and overhead under IRC §162, bypassing limitations on investment-related deductions.
The OBBBA’s permanence of TCJA individual rates heightens this advantage at the 37% top bracket. Consider a $1 million family office deducting $300K in costs, yielding $111K in federal savings. We assisted one HNW family in achieving $80K reductions by formalizing profits interests and documenting management services to related entities, ensuring compliance with substantial economic effect requirements against potential IRS challenges.
Successful implementation involves clear compensation beyond mere ownership returns, active decision-making, and arms-length agreements, transforming routine costs into powerful tax shields while supporting multigenerational alignment.
Optimize Wealth Transfers with the Permanent $15M Exemption
The OBBBA establishes a permanent $15 million estate, gift, and generation-skipping transfer exemption per individual starting in 2026, indexed annually for inflation and eliminating prior sunset concerns. Family offices strategically deploy family limited partnerships, irrevocable trusts, spousal lifetime access trusts, and annual gifting to shift appreciating assets efficiently. One client transferred $500K via discounted FLP interests in late 2025, avoiding approximately $200K in future 40% estate tax exposure. Valuation discounts of 20-40% on non-controlling interests amplify effectiveness.
Coordinate with enhanced SALT provisions and portability for couples to create layered protection, ensuring smooth intergenerational transitions without unnecessary tax erosion.
Takeaway: Proactive transfers under the elevated exemption preserve more wealth long-term. Develop customized approaches via a Strategy Call.
| Strategy | Example | Savings (37% Bracket) |
| §162 Deductions | $300K office expenses | $111K |
| Gifting/FLP | $500K assets transferred | $200K estate tax avoided |
| QSBS Exclusion | $1M stock gain | $370K |
Maximize QSBS and Other Investment Tax Breaks
Family offices consolidate portfolios to capitalize on OBBBA-enhanced Section 1202 QSBS rules for post-July 2025 stock: tiered exclusions reaching 100% after five years, up to $15 million per issuer (inflation-adjusted post-2026), and $75 million gross asset threshold. A $1 million eligible gain excludes $370K in tax at the top rate. We directed one office toward $150K savings through targeted QSBS positioning, combined with permanent 23% QBI benefits.
Layer with deferred vehicles, opportunity zones, and rollovers under Section 1045 to extend advantages, focusing on active qualified trades while avoiding service-sector exclusions.
Streamline Philanthropy for Deductions and Legacy Impact
Family offices orchestrate charitable efforts via donor-advised funds, private foundations, or charitable remainder trusts, bunching contributions to maximize itemized benefits under retained TCJA limits while offsetting ordinary income.
A $100K DAF contribution yields $37K immediate savings plus estate reduction. We facilitated $50K deductions for one client through foundation setup, aligning giving with multigenerational values.
Integrate with OBBBA’s temporary no-tax tips/overtime for staff incentives and enhanced above-line options to amplify both tax and societal outcomes.
Ensure Robust Compliance to Withstand Audits
Rising 2026 scrutiny on HNW structures demands airtight compliance, from Lender-aligned §162 documentation to substantial economic effect in FLPs. Penalties average $20K+ for lapses. We prevented a $30K adjustment for one client through meticulous records and preemptive reviews.
Quarterly audits, PTET elections for SALT workarounds, and proactive IRS alignment safeguard savings amid complex reporting.
Build Wealth with Family Offices
Family offices stand as indispensable tax planning powerhouses in 2026, harnessing OBBBA’s permanent TCJA extensions, $15M exemption, QSBS enhancements, §162 deductions, and integrated philanthropy/compliance to preserve substantial wealth ethically.
