The Truth About the Estate Tax Rate in California: What High-Net-Worth Individuals Are Missing in 2025
Many high-net-worth Californians believe estate taxes are a ticking time bomb ready to decimate their legacy. In truth, most affluent families overpay or fail to shield tens of millions due to outdated assumptions, overlooked IRS exemptions, and missed legal moves—a crisis hiding in plain sight for 2025’s new wealth transfer landscape.
This piece cuts through the myths and conflicting advice to deliver the practical, strategic playbook every successful Californian needs to preserve generational wealth.
Quick Answer
For 2025, California does not have its own estate tax. Only the federal estate tax applies, kicking in for estates over $13.61 million (per individual) for the tax year 2025. Yet, mistakes in structuring trusts, beneficiary designations, and gift strategies frequently cost families $100K–$15M unnecessarily. See our complete California estate planning guide here.
Understanding the “Estate Tax Rate California” Dilemma
Many believe California automatically imposes an estate tax because of its high property values and progressive income structure. This assumption keeps sophisticated families locked out of vital strategies that dramatically reduce (or eliminate) their federal exposure.
Let’s clarify:
- California Estate Tax 2025: No state estate tax. Repealed in 1982.
- Federal Estate Tax (2025): 40% on assets above the $13.61M exemption.
- Gift Tax: Separate but linked—annual gift exclusion is $18,000/person in 2025. Lifetime allocation folds into federal estate exemption.
- Inheritance Tax: None in California; some other states impose up to 16% (irrelevant in CA if all property stays here).
While many assume California adds to the federal estate tax bite, the truth is sharper: there is no estate tax rate California residents face at the state level. The entire burden comes from the federal rate—currently 40% on assets above $13.61M in 2025. This makes planning even more urgent for Californians, since high real estate and equity values push many estates over the threshold faster than they expect. IRS Form 706 and Publication 559 provide the governing rules for exemption, valuation, and tax calculation.
Despite this, most affluent Californians make two critical mistakes: (1) assuming there’s state tax when there isn’t, skipping advanced planning or, (2) misunderstanding how their federal estate tax exposure interacts with state property and gift laws—leaving their heirs with an unexpected tax bill. The IRS spells out the rules in Publication 559.
Why Most High-Net-Worth Californians Overpay Estate Tax
Red Flag Alert: The IRS collected over $27B in estate taxes for 2024, almost all from families who could’ve cut their bill with basic planning.
Common traps for California affluent families:
- Uncoordinated Trusts: Outdated AB trusts or poorly structured revocable trusts let millions through the cracks (especially for blended families or those with $15M–$50M).
- Busted Gifting Calendars: Advisors often miss IRS annual exclusions ($18K per person per year) or fail to “frontload” for education and 529 plans—costing tens of thousands in avoidable tax.
- Undervalued Closely Held Businesses: IRS expects formal valuations. Failing to document proper discounts leads to long audits and aggressive tax bills.
- Real Estate Ownership: Structuring assets in your own name exposes families to probate and creditors; titling through LLCs or irrevocable trusts can create wall of protection—and reduce future estate exposure by six-figures or more.

Strategies to Legally Minimize Federal Estate Tax Impact
Elite families surviving generational transitions do so because they wield highly specialized IRS-sanctioned moves—
- Spousal Portability Elections—Securing both spouses’ $13.61M exclusion can preserve $27.22M tax-free. Forgetting the 9-month post-death form (IRS Form 706) is the #1 error losing $5–$10M windfall for surviving spouse (see IRS Form 706).
- Dynasty Trusts—Utilize lifetime exemptions (soon to be cut in half in 2026) to fund multi-generational dynasty trusts. Example: Funding $10M in 2025 protects it from estate tax forever, potentially saving over $4M for heirs down the line.
- Grantor Retained Annuity Trusts (GRATs)—Freeze appreciation for fast-growing assets (e.g., tech stock, commercial properties). A $3M GRAT, if properly executed, can escape nearly $1.2M in estate taxes across a decade of growth.
- Irrevocable Life Insurance Trusts (ILITs)—Park life insurance outside taxable estate. A $5M policy passed to heirs directly—no estate tax haircut when the proper ILIT is established and annual exclusion gifts fund the premiums.
Each of the above requires precise timing, documentation, and compliance with specific IRS rules. Details are in IRS Publication 950.
Pro Tip: The federal exclusion will DROP by half in 2026 unless Congress acts. Waiting costs millions. High-net-worth Californians must complete large gifts before 12/31/2025 or risk losing $6M–$14M in tax shields.
Real-World Example: Multi-Generational Estate Tax Planning
Case Scenario: The Singh family—parents with $30M net worth, two children, ages 42 and 45. In 2024, they created a dynasty trust, transferring $10M in marketable securities to lock in the larger exemption. By proactively funding the trust ahead of the 2026 sunset, they secured over $4M in tax savings, avoided probate on major assets, and reduced audit risk. Their legal and administrative costs? Under $32,000.
ROI: $4M estate tax avoided / $32K in fees = 125x return.
Critical FAQ for 2025 California Estate Planning
Does California have an estate tax?
No—there’s no California state-level estate or inheritance tax as of 2025. Only the 40% federal tax applies for estates above $13.61M (per U.S. citizen).
What is the current federal estate tax exemption for 2025?
The exemption is $13.61M per person—double for married couples if surviving spouse files Form 706 election promptly after first spouse’s death (see Form 706 guidance).
How do gifts affect my estate tax exposure?
Lifetime gifts count against the $13.61M federal exemption (other than the annual $18K/year exclusion). Large gifts deplete your exemption but can be powerful wealth-anchoring tools, especially pre-2026 sunset.
What about real estate value in my estate?
Property owned directly is fully counted at fair market value at death. Use of LLCs, irrevocable trusts, or proper titling can transfer some appreciation out of your estate, and allow for family discounts.
What is a common mistake that costs families millions?
Failing to file spousal portability or not updating trusts after major tax law changes—by far the most common (and avoidable) errors for high-net-worth Californians.
KDA Case Study: High-Net-Worth Individual Shields $14M Legacy in California
Persona: HNW couple (mid-60s), retired tech founders, with blended family and $32M in liquid assets plus $12M in California real estate.
The Problem: Outmoded “AB trust” from the 1990s, no trust protector clause, exposure to both IRS and creditor litigation, and confusion about the interplay of California property law and federal estate tax.
KDA Solution: Our team led a full trust and gifting retrofit, coordinated with CA attorneys to establish a Nevada dynasty trust (for asset protection), executed $6M in tax-free gifts to children using combination of annual and lifetime exclusions, and funded two ILITs with $4M in coverage for grandkids.
Savings: Projected $8.7M in federal estate tax avoided (IRS Form 706, Publication 559), plus $1.2M in probate and legal fees saved. Cost: $45,000.
ROI: $8.7M saved / $45,000 fee = 193x first-year return (does not include future savings from dynasty trust growth or discounted asset valuations).
Red Flags and Myths: What the IRS Won’t Tell You
Red Flag Alert: Many wealthy families implement trusts but never retitle their assets—making the trust useless for estate tax purposes.
Myth Bust: “You don’t need planning if your assets are all titled jointly.” FALSE: Joint ownership does not shield assets from estate tax, nor does it substitute for trust or exclusion planning.
Pro Tip: Always coordinate with your estate attorney and accountant after any major tax change or personal milestone. The rules shift quickly—and the IRS is not in the business of reminding you to file for $10M in savings!
Next Steps: How to Build a Bulletproof Legacy in 2025
- Confirm all major assets are properly titled to trusts (not just listed in the documents).
- Update spousal and portability elections—in writing, with deadlines calendared.
- Fund existing trusts with large gifts before end of 2025 to maximize pre-sunset exemption.
- Explore dynasty trusts if your legacy plans extend to grandchildren or beyond California state lines.
- Document every move—IRS expects full paper trails for gifts, trusts, and discount valuations (see IRS Publication 950).

FAQ: What You Need to Know About the Estate Tax Rate in California
Will the IRS lower the exemption after 2025?
Yes—current law cuts the federal exemption by half starting in 2026 unless Congress acts. Schedule large gifts before then to lock in the higher shield.
What about California property/real estate?
All real estate gets a “step-up” in basis at death—minimizing capital gains for heirs—but does count at full fair market value for estate tax calculations. Only proper entity structuring or trust strategies can reduce this exposure.
Can LLCs help minimize estate taxes?
Yes—a properly set up LLC (especially in combination with a family limited partnership or irrevocable trust) allows “valuation discounts” for minority interests, reducing the portion of the LLC’s value subject to estate tax—for example, transferring a 25% LLC interest valued at $2M may be discounted to $1.5M on the estate tax return under the right conditions (Form 706 instructions reference this technique).
