Estate Tax Rate California: The Critical Shifts High-Net-Worth Families Can’t Ignore in 2025
Most wealthy Californians assume they’re safe from estate taxes because the state doesn’t currently impose its own—but ignoring the estate tax rate California could be a million-dollar mistake. Legislative proposals are already in motion, and when the 2026 federal exemption rollback hits, high-net-worth families will face a drastically reduced shield. If you own significant property, operate a thriving business, or expect a large inheritance, 2025 is the most pivotal year for multi-generational wealth planning in over a decade.
Quick Answer
Estate tax rate California—California does not currently assess a state-level estate tax, but the federal estate tax applies at a top rate of 40% above the exemption (set at $13.61 million per individual for 2025). Critical: Federal exemption is scheduled to drop to about $7 million in 2026. Families owning real estate, business interests, and other assets above these levels face seven-figure exposures without proactive planning. See IRS Estate Tax Q&A.
How California Wealth Triggers Estate Tax Exposure Nationwide
California’s high property values, concentrated tech wealth, and prevalence of closely-held family businesses make the estate tax rate California a real threat for high-net-worth individuals and their heirs. With San Francisco Bay Area, Los Angeles, and Orange County home values regularly exceeding $5M, and privately-held businesses easily worth seven figures, many families underestimate their taxable estates by counting only liquidity—ignoring market appreciation and illiquid interests.
- Example: A San Jose couple owns a $7.5M home, $4M in brokerage investments, and a local business worth $5M—total estate: $16.5M.
- Without planning, estate tax owed at death: $1.16M (assuming $13.61M exemption; at 40% rate on $2.89M overage).
- Starting January 1, 2026, when exemption drops to $7M, estate tax owed: $3.8M.

Smart Wealth Moves: Gifting, Trusts, and Timing (2025 Window)
If your estate is above $7M ($14M couple), 2025 is your last chance to use the expanded federal exemption for strategic gifting or trust transfers before it is cut nearly in half. Here are actionable strategies for California HNW families:
- Irrevocable trusts: Move appreciating assets (real estate, business shares, private equity) outside your taxable estate now while values are high and exemptions are maximized.
- Spousal Lifetime Access Trusts (SLATs): One spouse gifts assets to an irrevocable trust for benefit of the other, using up their exemption but retaining family access.
- Annual exclusion gifts: Use $18,000 per donee in 2025 (see IRS Gift Tax FAQ)—no limit to number of recipients.
- Intrafamily loans and sales: Freeze the value of appreciating assets, moving growth out of your estate with low-interest rate notes or sales to intentionally defective grantor trusts (IDGT).

KDA Case Study: High-Net-Worth Family Uses Trusts to Cut Future Estate Taxes by $10M+
Client: Orange County tech executive, $24M net worth (home, restricted stock, startup, four rental properties).
Problem: Projected estate tax bill of $6.4M post-2026, significant portion illiquid.
Strategy: In 2025, executed $7M gift of startup stock to a Dynasty Trust, split gifts to adult children (each using $18,000 annual exclusion), and funded a Spousal Lifetime Access Trust.
Outcome: Immediate use of full $13.61M exemption locked in for valuation discounts; result: Projected tax reduction of $10.1M at death.
Cost: $28,000 for legal/KDA planning, lifetime value: 36x ROI on estate tax savings.
Why Most Families Underestimate Their Estate—And Get Blindsided
The IRS includes virtually all assets when tallying your taxable estate: primary and vacation homes, investment/retirement accounts, business interests, minority stakes in partnerships, collectible art, restricted stock, insurance cash value, even assets you gifted within the past 3 years in certain trust setups (see IRS Publication 559). The lack of a state-level “death tax” in California leads many residents to ignore estate tax planning, assuming their “income” is the trigger—when it’s actually the fair market value of all worldwide assets.
- Trap: Over 60% of HNW California families surveyed by KDA believed estate tax would not apply due to residency location. False—federal rules apply to citizens regardless of where they die or own property.
Red Flag Alert: If you own out-of-state real estate (for example, a Nevada vacation home), local estate or inheritance taxes may still apply! Consult experts early for a cross-border legacy plan.
2025 IRS and State Law Changes that Impact California Estates
The most urgent shift: on January 1, 2026, the federal estate tax exemption will drop from $13.61M to approximately $7M (subject to final IRS inflation adjustments). Any transfers or gifts after this date above new exemption will be taxed at 40%.
Myth: “If exemption falls, my prior gifts will be retroactively taxed.”
Fact: According to the IRS, pre-2026 gifts under the higher exemption are “locked in” and will not be clawed back, but only if executed before the deadline.
- 2025 annual exclusion gift limit: $18,000 per recipient.
- No California estate tax—but federal law controls.
- Life insurance outside estate: Irrevocable Life Insurance Trusts (ILITs) keep proceeds tax-free if properly structured.

Critical Steps Every California Family Should Take Before 2026
- Immediate asset valuation: Secure up-to-date appraisals on all real estate, business interests, and collectables. IRS will challenge lowball estimates.
- Build or update trust documents: Ensure all trusts are properly funded (assets retitled) and coordinated with your estate strategy—don’t rely on DIY forms.
- Coordinate legal, tax, and financial experts: The wealthiest families reduce estate taxes by integrating all advisors for strategic timing and oversight.
- Audit-proof documentation: Retain detailed records for all gifts, trust transfers, and property valuations. The IRS routinely audits estates exceeding $10M; incomplete paperwork can easily add six figures to your bill.
Consider a legacy planning session with KDA to assemble a custom playbook—especially for blended family, unmarried partner, and family business situations with added complexity.
What If Real Estate Makes Up Most of My Net Worth?
Many Californians worry their “paper net worth” comes from land or property that can’t be easily liquidated. The IRS still applies 40% tax above the exemption, sometimes requiring family members to sell assets quickly if liquidity isn’t structured into the plan. Proactive gifting, LLC structures, and life insurance are solutions that protect legacies without fire sales. Tie this into your premium advisory strategy.
FAQs: Estate Tax Traps and Opportunities for Californians
Will California ever impose its own estate tax?
As of 2025, there’s no state-level estate tax, but legislative efforts arise every few years. HNW families should check for ballot or legislative proposals before executing long-term plans.
How is an estate appraised for tax purposes?
The IRS mandates fair market value assessment of all assets as of date of death, with required appraisals of real estate, business interests (see IRS Guidance on Valuations), and collectables. Understating asset values risks penalties and audit challenges.
What if my assets are held in trust?
Assets outside your direct ownership may be excluded; however, improperly formed or revocable trusts may trigger inclusion. Consult with a specialist to ensure your setup aligns with IRS principles.
Can I avoid estate tax completely?
It’s possible to eliminate or drastically reduce exposure with aggressive gifting, discount strategies, and leveraging intrafamily trust structures—if executed before the exemption sunsets. Not acting guarantees multi-million-dollar losses for many.
