Proposition 40: 10 Things California Families Should Know

By James G. Burns, Esq.

Your family may own less than a billion dollars outright and still need to examine a trust interest. That does not mean Proposition 40 taxes every beneficiary. It means the proposed definitions must be read before anyone gives you an automatic yes or no.

As of October 25, 2026, Proposition 40 remains a pending November 3 ballot measure, not current law. Its proposed January 1, 2026 tax-obligation date and December 31, 2026 valuation date perform different jobs. Its trust rules also distinguish grantor trusts, applicable trusts and interests distributable to beneficiaries.

This article turns those distinctions into ten review questions for Orange County and Aliso Viejo families. Our earlier Proposition 40 overview explains the broader proposal. Here, the assignment is narrower: assemble the evidence needed to classify the family, the trust and the assets accurately.

1. A Pending Proposal Is Not a Tax Bill

The official title and summary describes a proposed one-time tax of up to 5% on certain taxpayers with covered assets valued over $1 billion. The proposal is an initiative constitutional amendment and statute. An election outcome, effectiveness and any controlling legal developments still matter.

Do not authorize a gift, trustee replacement or relocation simply because someone says California has already imposed this tax. Ask which provision is current law, which is proposed and which conclusion remains an assumption. Write those labels beside the advice.

Risk Exposure Mapping begins there. The purpose is to identify a possible exposure and the information needed to evaluate it. A proposal can justify collecting records without justifying an immediate restructuring.

2. January 1 and December 31 Answer Different Questions

Proposed sections 50308(a) and (n) use California residence on January 1, 2026 to identify an applicable individual. Proposed section 50308(o) supplies December 31, 2026 as the valuation date. Proposed section 50301 separates the classification date from measurement of the net worth subject to tax.

Put both dates on the review sheet. A current account statement does not prove January residence. A January balance sheet does not establish December value. The asset history connecting the dates also matters because the proposed text addresses transfers and interests acquired or disposed of during the year.

A later move does not itself rewrite the proposed January test. Preserve the actual chronology rather than treating the date of a new driver's license or mailing address as a complete answer.

3. Residence Requires Evidence, Not a Mailing Label

The proposed definition refers to existing Revenue and Taxation Code sections 17014 and 17015.5. Residence must be examined under the applicable rules and facts. Domicile, homes, physical presence, business activity and family connections may be relevant; no single record should be presented as universally decisive.

Prepare a dated timeline with supporting documents. Identify where the family actually lived, worked and maintained its connections. Distinguish a plan to move from a completed move, and a completed move from a conclusion about tax residence.

Do not manufacture records or backdate an explanation. If documents conflict, flag the conflict for counsel. The review is stronger when uncertainty is visible than when someone selects only the papers that support the desired conclusion.

4. The Threshold and the Rate Are Separate Calculations

Proposed section 50301(a) addresses applicable individuals with net worth of $1 billion or more and applicable trusts. But the phrase 5% tax does not supply the entire calculation. Under proposed section 50301(b), the individual rate is reduced below $1.1 billion by 0.1 percentage point for each $2 million below that amount, with a floor of zero. That phase-down is expressly for individuals other than trusts.

Classification, net worth, the rate, exclusions and apportionment require separate work. Do not multiply a family's rough balance-sheet total by 5% and call the result a liability.

Record which calculation is preliminary and which professional is responsible for checking it. A useful worksheet shows the assumptions as clearly as the estimated number.

5. Classify the Trust Before Classifying the Beneficiary

Proposed section 50308(b) defines an applicable trust through specified transferor, wealth and related-person conditions. It excludes grantor trusts and tax-exempt trusts from that general definition, contains allocation rules for multiple contributors, and provides elections that can affect separate trust treatment. It is not a synonym for any trust with a California connection.

The proposal's definition of grantor trust is also broader than an income-tax label alone. Proposed section 50308(e) includes income-tax grantor trusts and trusts whose assets would be included in the grantor's estate for federal transfer-tax purposes.

Obtain the complete instrument, amendments, transfer history and relevant ownership analysis. Mark the proposed classification separately from the trust's existing federal and California income-tax reporting. An EIN, an irrevocable label or a trustee in another state does not perform that analysis.

6. Distributable Assets Can Matter Without a Payment

Proposed section 50303(c)(6)(C) generally treats a beneficiary as owning trust assets to the extent they are distributable to that beneficiary, whether distributed or not. The same provision expressly excludes assets of an applicable trust from that beneficiary-attribution rule.

Both parts matter. It would be misleading to announce a tax on every trust beneficiary. It would also be misleading to stop reviewing a beneficiary merely because directly owned assets fall below a billion dollars. Attributed interests could affect the threshold analysis, depending on the definitions and actual rights.

Ask what the beneficiary may receive, when, under which conditions and through whose decision. Record mandatory rights, trustee discretion and any competing interests. Do not treat the trust's total value as automatically attributable to each beneficiary, or treat a possible future payment as proof of a present distributable interest.

7. Preserve Transfer and Valuation Records Together

The proposed transferor rules in section 50303(c)(6)(B) make the contribution history important. They address property transferred to nongrantor, nonexempt trusts for threshold purposes and contain additional treatment for 2025 and 2026 transfers. A transfer should not simply disappear from the review worksheet because title changed.

Obtain dated transfer documents, contribution schedules, capitalization records and the basis for valuations. Where several people contributed, identify who transferred what rather than assuming the whole trust has one funding history.

For business interests, the proposed text contains valuation presumptions, including rules concerning control and profits interests, together with procedures for challenging certain presumed results. A financing-round headline or an internal estimate is not a completed analysis. Ask the valuation professional which proposed rule applies and what evidence supports a different result, if asserted.

8. Ownership Form Can Change the Asset Inquiry

Proposed section 50303(c)(4) addresses real property held directly or through a revocable trust. Other provisions address business interests, retirement arrangements and additional asset categories. The official summary's general exclusions should not be turned into a blanket conclusion about every entity or trust that holds an underlying asset.

Map the ownership chain: person, trust, entity and underlying property. Keep each layer distinct. A family may describe its investment as real estate while its legal interest is in an entity. That is a reason to examine the text, not a reason to assume either inclusion or exclusion.

Our trust-situs discussion separates administration, governing law and taxation. Those existing planning questions remain useful, but moving administration does not replace Proposition 40's proposed attribution analysis.

9. A Large Value Does Not Supply Spendable Cash

A founder can hold valuable company shares without a ready market. A beneficiary can have an attributed interest without receiving cash. Build a liquidity schedule alongside the legal analysis: available funds, restrictions, lender terms, expected expenses and the effect of any sale or borrowing on control.

The proposed text offers installment payments with additional charges and separately addresses an optional deferral account. Neither should be described as automatic forgiveness or a universally available solution. The obligations, eligibility, continuing reporting and effects on successors need review before any election.

Proposed section 50306 starts with a standard apportionment rule and provides alternative-apportionment procedures with evidentiary requirements. Relief is not established merely by owning assets outside California. Keep the legal entitlement to a position separate from the practical ability to fund a possible payment.

10. Build a Review File That Survives the Election

The official analysis describes potential conflicts involving Propositions 41 and 42. A majority yes vote on Proposition 40 would not, by itself, answer every question about its operation. Review actual results, the competing texts and controlling developments. Do not assume either certain implementation or inevitable invalidation.

Give the team a usable record now. The following is a planning worksheet, not a tax return or a conclusion that the family is covered.

What remains conditional or unresolved?

Consider a hypothetical beneficiary with directly owned assets below the proposed threshold and an interest in a substantial family trust. The next step is not an immediate distribution or an automatic exemption claim. Counsel first classifies the trust and distribution rights. The CPA and valuation professional then coordinate the relevant amounts. This is an illustration, not a client result.

Risk Exposure Mapping identifies those connections before document selection. Control Architecture coordinates authority, ownership and intended support. Implementation assigns the records, professional reviews and authorized tasks. Maintain that discipline even if the measure fails: accurate ownership and a usable family handoff still matter.

Frequently Asked Questions

Is Proposition 40 Current Law?

No. As of October 25, 2026, it remains a pending November 3 ballot measure. Its proposed provisions should not be described as already operative.

Which Date Determines the Proposed Residence Test?

The text defines January 1, 2026 as the tax-obligation date and uses that date in identifying applicable individuals. December 31 is the separate proposed valuation date.

Is Every Covered Individual Charged a Flat 5%?

No. Proposed section 50301(b) contains the individual rate phase-down below $1.1 billion. Applicable-trust treatment differs. Review the actual calculation rather than relying on a headline.

Can a Beneficiary Below a Billion Dollars Be Affected?

Possibly. Distributable trust assets can affect the proposed ownership and threshold analysis. The applicable-trust exception and the beneficiary's actual rights must be examined; ordinary trust beneficiary status alone does not establish tax liability.

Does an Out-of-State Trustee End the Inquiry?

No. The proposed trust provisions include rules that are not confined to trusts resident in California. Location, classification, transfer history and beneficiary rights require separate findings.

Should We Move Assets Before the Election?

Not solely because of this proposal. Review existing duties and the tax, control, creditor and family consequences first. Do not assume a transfer, move or eventual lawsuit guarantees a particular result.

Short Summary

Read the two dates separately, classify the trust before attributing assets, and preserve the records behind residence, value and liquidity. Proposition 40 remains a proposal. A documented review is useful preparation; a headline-driven transfer is not a substitute for analysis.

Arrange the Appropriate Planning Review

For advanced trust, ownership and family-transition planning, use the firm's planning intake and arrange an appropriate billable consultation through the office at (949) 305-8642. This work is separate from a qualifying no-charge foundational estate-planning briefing, which requires the Risk Exposure Mapping Form. Tax-return preparation and tax controversy require the appropriate separate professional engagement.
