The Real Estate Investor’s Deep Dive: Navigating California Estate Tax in 2025 for Maximum Wealth Preservation
Most high-net-worth Californians wrongly assume that their real estate portfolio is protected from crushing estate taxes just because California has no state-level estate tax. The truth? Federal estate tax still applies aggressively, and legislative whispers suggest California could revive estate taxes in the future. If your real estate assets push your net worth above $20 million, and you haven’t updated your estate plan for 2025, you’re at risk of losing millions to taxes instead of passing wealth to the next generation.
Quick Answer: How Estate Taxes Impact Real Estate Investors in California for 2025
California estate tax does not exist in 2025, but high-value estates face the 40% federal estate tax on amounts above the $13.61 million (per individual) exemption. Real estate heavy portfolios are vulnerable to steep tax hits if not shielded by advanced planning. Recent IRS rules on valuation discounts, Qualified Personal Residence Trusts (QPRTs), and stepped-up basis strategies offer major savings—if you act before gifting or death.
Wealth at Risk: Calculating Potential Estate Tax for California Real Estate Investors
Let’s break it down. If you own $28 million in California real estate and stop updating your estate plan, here’s what happens in 2025:
- Federal exemption is $13.61 million per person ($27.22 million for married couples. IRS Estate Tax).
- Real estate portfolios over that get hammered with a 40% estate tax.
- Example: John and Maria, both 65, own multi-family units in Santa Monica worth $28 million by 2025. If they die without optimizations:
- $28M – $27.22M = $780,000 exposed to 40% estate tax = $312,000 tax bill, right off the top.
- And if the exemption sunsets to $7 million per person (as scheduled for 2026), their exposed amount skyrockets: $28M – $14M = $14M × 40% = $5.6 million in taxes.
Faulty assumption: “California has no estate tax, so I’m safe.” This is a dangerous myth for any HNW investor.
Strategy One: QPRTs and GRATs—Locking in Low Values
For properties you intend for heirs, consider a Qualified Personal Residence Trust (QPRT) or Grantor Retained Annuity Trust (GRAT). These trusts freeze property value at today’s rate, allowing growth to accrue outside your estate and under current, more generous exemption rules.
- Example: Jane, 59, transfers her $7 million Carmel beach house into a QPRT in 2025. She sets a 10-year term and continues living there rent-free. When the house rises to $12 million in value by 2035, only the initial $7 million counts as a gift. Her heirs avoid estate tax on the $5 million future appreciation—a $2 million+ tax savings.
Pro tip: The key is acting before exemption levels drop. You can’t retroactively claim the higher exemption once it’s gone.
Don’t Overlook Stepped-Up Basis in 2025
Heirs inherit real estate at its full fair market value on the death of the owner, erasing capital gains tax on appreciation up to that date. But with proposed legislative changes, some HNW families could lose access to this stepped-up basis—especially if assets are wrapped up in certain trusts or entities.
- Example: Robert’s parents bought a Cupertino fourplex in the 1980s for $200,000. At his father’s death in 2025, the property’s value is $4 million. The new basis for heirs is $4 million, eliminating $3.8 million in capital gains—worth nearly $950,000 in tax savings at California and federal rates combined (assuming no legislative changes remove this benefit).
Trap: Holding property in certain irrevocable trusts without careful tax planning can inadvertently forfeit stepped-up basis. Get KDA review for each entity and trust now.
Where the IRS Is Cracking Down: Improper Discounts and Appraisals
The IRS isn’t blind to aggressive estate tax strategies. In 2025, they are auditing:
- Overstated minority or marketability discounts for limited partnerships (FLPs/LLCs).
- Lowball valuations lacking current comp data for California real estate.
Red Flag Alert: If your estate appraiser undervalues by more than 10% of market, the IRS can substitute their own assessment and add penalties (see IRS Publication 561).
How to Legally Reduce Your Estate Tax Obligation in California
- Gift Real Estate Now: Use your 2025 $13.61M exemption (or $27.22M for couples). After 2025, it could drop to $7M per person. Advanced gifts to trusts work best; direct gifts can lose asset control.
- Freeze Values with Trusts: Set up QPRTs for residences and GRATs for income-earning properties. Growth escapes tax. Consult for custom entity structure.
- Leverage Valuation Discounts (Carefully!): Properly structured family entities (LLCs/LPs) can reduce taxable value of illiquid assets by 15–30%, but abusive discounts are being audited aggressively in California as of 2025.
- Reassess Entity Structures: Many old holding LLCs set up between 2000–2015 are tax traps now. Review your SMLLC vs. multi-member setups, and update operating agreements for 2025 law changes.
- Get Pro Appraisals: Demand market-based, IRS-compliant appraisals for all properties and business interests.

Why Most Real Estate Investors Miss These Moves
Most high-net-worth California real estate investors leave six- and seven-figure tax breaks on the table due to:
- Assuming their spouse or heirs “will handle it.”
- Opinion-based planning: Real estate is “recession-proof”—but IRS rules aren’t.
- Focusing only on income strategies (1031s, depreciation) and never on transfer/tax reduction strategies.
Myth bust: “If my assets are in a trust, I’m automatically protected.” Many trusts (e.g., revocable living trusts) don’t shield against estate tax, only probate. Sophisticated, multi-entity planning with QPRTs, SLATs, and discounting is required.
Integrating Real Estate with Holistic Wealth Transfer
Estate tax isn’t your only concern. California’s complex property tax reassessment (Prop 19), capital gains stacking, and passive income rules all interplay with estate tax planning.
- Scenario: Sally, a Newport Beach investor, uses LLCs for her rental properties. KDA implements a hybrid plan: gifting shares in LLCs to heirs, using valuation discounts, layering a QPRT, and analyzing Prop 19 risk for each transfer. Net estate tax savings: $2.4 million, property tax savings: $220,000 over ten years.
Advanced tax planning in 2025 isn’t just about one trust—it’s about the right sequencing of gifts, entity tweaks, and property valuations.
The Real KDA Case Study: HNW Real Estate Investor
KDA Case Study: High-Net-Worth Real Estate Portfolio Owner Slashes Estate Tax by 42%
Persona: High-net-worth California family, ages 60–68, real estate assets exceeding $36 million—including commercial properties, vacation rentals, and an extensive personal residence. Their initial plan involved a revocable living trust and outdated LLCs. Through deep-dive review, KDA’s advisory team spotted:
- Lack of valuation discounts on minority LLC interests
- No QPRT or GRAT for fast-appreciating properties
- Inefficient property holding structure (several properties owned directly)
Actions:
- Moved primary and secondary homes into QPRTs, locking in 2025 valuations
- Gifted minority LLC shares to heirs, with a 28% IRS-approved discount
- Restructured holding companies for asset protection and step-up basis qualification
Outcome:
- Estimated estate tax liability dropped from $7.3 million to $4.2 million—a $3.1 million savings
- Total KDA planning fees: $36,000 ($18,000 in year 1, $18,000 in year 2)
- First-year ROI: 43x net of fees
Client testimonial: “I had no idea merely shifting titles and updating my trust with KDA’s team would save my family this much. They found gaps my old lawyer and CPA missed.”
What If California Reinstates State Estate Tax?
Current 2025 status: No estate tax at the state level, but federal rules hit portfolios hard. California legislators have proposed various estate tax bills in the last five years (see SB 378, 2020), so HNW families should futureproof with flexible, multi-generational trusts and triggers in their plans. Set annual reviews to adapt—for now, focus on aggressive use of current federal exemptions.

FAQ: California Estate Tax, 2025 Edition
Does California impose estate tax in 2025?
No. For 2025, only the federal government imposes an estate tax (currently 40%). But legislation could change – ongoing reviews required. See official IRS guidance.
What is the current federal exemption?
For 2025, $13.61 million per individual. Married couples get $27.22 million if both are U.S. citizens (IRS Revenue Procedure 2024-42).
Will the estate tax exemption decrease after 2025?
Yes, under current law, the exemption returns to 2017 levels (about $7 million per person adjusted for inflation) in 2026 unless Congress acts.
How does step-up in basis benefit California real estate heirs?
Heirs receive property at its market value on owner’s death. A $2 million inherited property sold for $2.1 million only triggers tax on the $100,000 gain—not original purchase price.
Should I use a QPRT or GRAT for investment property?
QPRT works best for primary or vacation homes you want heirs to own outright. GRATs are typically for income-generating assets. Coordination is crucial.
