How to Reduce Estate Taxes: Strategies High-Net-Worth Californians Can’t Afford to Miss in 2026
Most high-net-worth Californians believe that if you work hard, build your legacy, and follow the rules, your heirs will inherit what you’ve earned. Yet too many discover—far too late—that failing to proactively plan for estate taxes can cost their family $500,000, $2 million, or even more. For families with $10M+ in assets, the lack of a tailored estate tax strategy isn’t just an oversight—it’s a direct threat to generational wealth.
Quick Answer
How to reduce estate taxes: In 2026, Californians with significant assets must use a multi-layered plan to shield family wealth from estate taxes. Critical defenses include irrevocable trusts, annual gifting programs, valuation discounts, charitable strategies, and entity structuring for high-risk assets. Deductions, exemptions, and advanced legal structures change rapidly year to year—strategically layering these proactively can mean the difference between a tax bill of millions or pennies on the dollar. Every high-net-worth family needs this plan reviewed annually as state and federal laws evolve. (See IRS estate tax guidance.)
When clients ask how to reduce estate taxes, the first lever we review is the timing and structure of transfers before the exemption drops in 2026. A well-designed plan captures today’s higher exemption, shifts future appreciation out of the taxable estate, and locks in valuation discounts that the IRS currently allows under Sections 2031 and 2704. High-net-worth families who move early typically see 25%–60% reductions in projected tax liability compared to those who wait until exemption levels reset.
Understanding Estate Taxes: What’s at Stake for High-Net-Worth Californians
The federal estate tax exemption is set to drop dramatically in 2026, slashing the threshold from $12.92M per individual (2023) or $25.84M per couple, down to roughly $7M per individual or $14M per couple. In California, while there is currently no state estate tax, multiple wealth tax proposals are under legislative review that could change the game by 2026 and beyond.
Scenario: Camilla and David, a married couple in Silicon Valley, have an estate worth $35M. In 2025, with the unified credit, only $9.16M of their assets would be taxed at the 40% estate tax rate. But in 2026, if the exemption falls to $14M as projected, $21M of their estate could be subject to federal tax—amounting to a potential $8.4M IRS bill overnight. No entity structuring or gifting plan = disastrous outcome for heirs.
Estate taxes target assets including real estate, marketable securities, privately held business interests, and even life insurance proceeds (if not properly structured). For high-net-worth Californians, it’s not just about protecting homes and portfolios, but also business succession, privacy, and philanthropic goals.
Layered Strategies High-Net-Worth Families Must Use in 2026
There’s no single ‘silver bullet’ to eliminate estate taxes, but a combination of legal and tax maneuvers can slash your exposure—in some cases from 40% to less than 10% effective taxation.
1. Irrevocable Trusts (IDGT, SLAT, GRAT, ILIT, etc.)
- Intentionally Defective Grantor Trust (IDGT): Transfers appreciating assets out of estate; future growth escapes estate tax. Example: Transferring $10M of private business shares to an IDGT shields their appreciation. Savings can exceed $1.5M for a $4M appreciating asset.
- Spousal Lifetime Access Trust (SLAT): Spouses shift assets into trust to lock in today’s exemption before it drops, while retaining indirect access to income. Example: Jane and Jorge fund a SLAT with $7M each in 2025, eliminating $5M+ in future estate tax if values grow.
- Grantor Retained Annuity Trust (GRAT): “Freeze” value of appreciating assets for transfer with little or no gift tax.
- Irrevocable Life Insurance Trust (ILIT): Keeps insurance proceeds out of taxable estate—if structured correctly per IRS guidelines.
2. Annual Gifting Programs & Lifetime Exemption Usage
- Use the $18,000 (2025) annual exclusion per recipient for tax-free gifts. Gifting $18,000 to each of 10 family members removes $180,000 per year from taxable estate—$10M moved over 30 years with no taxes due.
- Leverage lifetime gift exclusion before it resets in 2026 ($14M for married couples projected). Strategic use of exemption allows HNW families to shift future appreciation out of the IRS’s reach.
3. Valuation Discounts for Business and Real Estate Holdings
- Discounts for lack of marketability/lack of control can reduce business interests’ taxable value by as much as 30%. For a $12M LLC interest passed to heirs, a 30% discount could slash taxable value to $8.4M—saving $1.44M in federal estate tax.
- Professional valuation and legal documentation are essential—IRS audits aggressively challenge unsupported discounts (see IRS business valuation rules).
4. Charitable Strategies (CRTs, CLTs, Foundations)
- Charitable Remainder Trust (CRT): Transfer asset into trust, receive income stream, and charity receives remainder at end—assets are excluded from your estate for tax purposes. Example: A $5M appreciated stock portfolio moved to CRT avoids capital gains+reduces estate tax, and can yield $1.3M more for charity & heirs vs. outright gift.
- Private Foundation: Allows HNW family to direct charitable giving—removes assets from estate, while maintaining control over grantmaking.
5. Entity Structuring and Asset Protection
- LLCs, FLPs, and S Corps used for concentrated real estate or business holdings can optimize control, enable gifting, and reduce exposure through discounts.
- An LLC holding family real estate can simplify transfer planning, reduce taxable value, and provide liability protection—all while ensuring property remains in family hands across generations.

KDA Case Study: Tech Founder Minimizes Estate Taxes Using Multi-Layer Strategy
Persona: High-Net-Worth Individual (Silicon Valley tech founder).
Problem: Susan, with $45M in assets (stock, real estate, business interests), was on track for an estimated $12M federal estate tax bill in 2026 based on projected exemption drop. She wanted to maximize inheritance for her two children and maintain control of charitable giving.
What KDA did:
1. Established two SLATs before 2026 reset, removing $14M from future estate.
2. Transferred $9M of business shares into an IDGT, locking in lower valuation and shielding appreciation from estate taxes.
3. Created a family LLC to hold real estate, applying a 28% minority interest discount, cutting taxes by $1.3M.
4. Set up a private foundation for philanthropy and further estate reduction.
Outcome: Susan’s taxable estate was reduced by over $18M, with $6.5M in projected tax savings—3.4x ROI compared to planning fees. Her philanthropic goals were fully realized, and family assets are now protected for future generations.

Why Most High-Net-Worth Californians Overpay Estate Taxes
The same mistakes happen over and over: waiting until the year before a liquidity event, not updating plans when exemptions change, failing to value assets for discounting, ignoring new legal structures, or assuming California laws will remain tax-friendly. Underestimating life insurance proceeds or failing to maximize current lifetime exemption can easily trigger seven-figure tax liabilities. IRS rules change every year (see Estate Tax guidance), and California legislature is actively pursuing new wealth taxes as of 2025–2026.
Red Flag Alert: If you haven’t reviewed your plan since 2022, you’re at risk for headache surprises when federal rules sunset in 2026. Annual plan reviews and proactive moves are mandatory—not optional.
Pro Tip: Annual Gifting Privileges Stack Quickly
Don’t underestimate the impact of annual gifting. Moving $18,000 per recipient per year out of your estate may seem slow, but for a family of five grandchildren, that’s $90,000 moved annually—$900,000 in under a decade. Stack that with lifetime exemption usage, ILITs, and GRATs, and your exposure can shrink dramatically. No gifting plan = money left on the table for IRS collection. (IRS rules on gift exclusion: IRS Gift Tax Guidance.)
What If the California Wealth Tax Passes?
California’s proposed wealth tax (as debated in 2025-2026) creates a moving target for planning. Even though there is no state-level estate tax today, pending proposals could expose estates above $15M–$50M to new state levies. HNW families must monitor legislative updates, act quickly when new thresholds are announced, and avoid “wait-and-see” paralysis. Pre-2026 is especially valuable for lock-in, as post-enactment changes may not allow full retroactive protections.
FAQs for Reducing Estate Taxes in 2026
How Much Can I Gift Without Tax in 2026?
The projected annual exclusion is $18,000 per recipient. Married couples can consent to split gifts, doubling capacity. For lifetime gifts, the combined exemption is set to reduce to roughly $14M per couple in 2026 unless Congress acts. Always check current figures against IRS updates.
What Happens If I Inherit an IRA or Property?
IRAs pass by beneficiary designation, not through the estate, but may still be subject to income tax. Real property included in estate value for tax purposes, with stepped-up basis if held at death. Trusts can shelter both, but must be set up in advance and coordinated with your tax advisor (see IRS guideline.)
Can I Use LLCs or Family Partnerships for Greater Control?
Yes. Proper structuring increases asset protection, simplifies gifting, and enhances control as children or charities become future owners. Discounts also apply—especially for minority interests in family LLCs holding real estate or business. See our premium advisory services for hands-on implementation guidance.
