How to Minimize Property Taxes for Your Children Under Prop 19

Under Proposition 19, exactly one thing preserves your low property tax base for your children: one of them makes your home their principal residence within a year of your death and claims the homeowners’ exemption.

Everything else on this page exists to protect that one outcome, or to plan sensibly for the case where it will not happen. There is no clever structure that substitutes for it. Trusts do not. Entities do not. Gifting does not.

So the planning work is narrower than most people expect, and more urgent. It starts with a conversation, and it has to happen while you are alive.

Step 1: Have the Occupancy Conversation

This is the whole plan. Everything else is implementation.

Ask each of your children directly: would you actually move into this house and make it your main home within a year?

Treat it as a practical question, not a sentimental one. Their job, their own mortgage, their spouse, their children’s schools, and their honest willingness all bear on the answer. A child who says yes to please you and then does not move in produces the same outcome as a child who says no.

If one child genuinely will, the rest of this page tells you how to protect that.

If none will, that is valuable information rather than a failure. The base will not survive, and you can plan for a sale, for the carrying cost, or for a different disposition of the property, deliberately and in advance.

Avoiding this conversation is the single most common planning failure. Families assume a child will keep the home and its low tax bill, never confirm it, and lose the exclusion by default.

Step 2: Direct the Home to the Child Who Will Live There

If several children inherit the home as co-owners, only the resident child keeps the low base, and only on their share. The other shares reassess to market value.

If the home goes entirely to the child who will live there, that child owns one hundred percent of a qualifying property, and the whole home keeps the low base.

A worked example. A home with a factored base year value of $230,000 and a market value of $900,000, three children, one resident.

• Split three ways: new taxable value about $677,000, or roughly $6,800 a year at one percent.
• Directed to the resident child: new taxable value $230,000, or roughly $2,300 a year.

About $4,500 a year, produced by drafting rather than by anything the children do.

Balance the other children with different assets. If the estate lacks enough other assets, life insurance is a common way to equalize without splitting the house.

Step 3: Authorize Non-Pro-Rata Distribution

A non-pro-rata distribution lets your trustee give each beneficiary different assets of comparable value rather than a fractional share of everything. It is what makes step two possible when you want the outcome to stay flexible.

Your trust must permit it. Many do; some do not. Ask your attorney to confirm, and to add the authority if it is missing. This is usually a straightforward amendment.

A related trap worth avoiding. If the children first inherit as co-owners and one later buys the others out with outside funds, that buyout is a sibling-to-sibling sale. It gets no exclusion, and the purchased shares reassess. Handling the allocation during trust or estate administration, before distribution, avoids that result. The mechanics are technical enough to need a professional.

Step 4: Fund Your Trust, and Tell Your Trustee About the Clock

Two failures, both preventable, both common.

An unfunded trust does nothing. If the deed still names you individually rather than as trustee, the home goes through probate despite the trust existing. Check the deed.

Probate can outrun the one-year clock. California probate commonly runs longer than twelve months, and the clock starts at your death, not at the end of the process. A funded trust lets a successor trustee act within days instead.

Leave written instructions with your trust documents saying that the Proposition 19 occupancy clock starts at the date of death, that the resident child should move in promptly without waiting for administration to conclude, and that both BOE-266 and BOE-19-P must be filed. This one page has saved families tens of thousands of dollars.

Step 5: Do Not Gift the Home During Your Life

It feels like getting ahead of the problem. It costs twice.

Reassessment now. A lifetime gift is a change in ownership, so the property is reassessed immediately rather than at your death.

Capital gains later. Inheriting generally resets the property’s income tax cost basis to market value at death, the stepped-up basis. A gift carries your original basis forward instead. A home bought for $80,000 and worth $900,000 carries roughly $820,000 of built-in gain, and gifting hands that gain to your children.

The same reasoning rules out adding children to title now, which transfers and reassesses their share immediately and loses the step-up on it.

Step 6: Know What Cannot Be Protected

Honest planning means naming the limits.

Rentals, second homes, vacation homes, commercial buildings, and investment land receive no exclusion and reassess to full market value with no cap. There is no move-in fix, because they were never your principal residence.

For these, the planning question is not how to preserve the base. It is whether holding the property still makes sense once the reassessed tax comes out of the income, and whether your children want to be landlords at all. That conversation is worth having with them and with your CPA.

Family farms are the exception. Land under cultivation, used for pasture or grazing, or producing an agricultural commodity keeps its low base subject to the value cap, and nobody has to live on it. If your holdings include anything agricultural, examine this closely.

Step 7: Check Where You Sit Against the Value Cap

Even a qualifying home is capped at your factored base year value plus $1,044,586 for transfers from February 16, 2025 through February 15, 2027. Above that ceiling, the excess is added to the base as a partial reassessment.

Pull the factored base year value from your current tax bill, add the exclusion amount, and compare the result to a realistic market value. Below the ceiling, moving in preserves the base entirely. Above it, moving in still saves a great deal, and your child should know the annual carrying cost before the one-year deadline rather than after it.

Step 8: Get the Right Professionals Involved

Three conversations, none optional on an asset this size.

An estate planning attorney drafts or amends the trust, confirms the non-pro-rata authority, and handles the distribution language.

A CPA weighs the income tax side, particularly the stepped-up basis and any keep-or-sell decision on investment property.

A real estate professional who knows Proposition 19 can value the property realistically, estimate the transferred or capped base, and tell you what your county assessor expects.

Summary

• Preserving your low base requires one child to make the home their principal residence within a year of your death and claim the homeowners’ exemption.
• Start with an honest occupancy conversation, and plan for both answers.
• Direct the home entirely to the resident child rather than splitting it among siblings.
• Authorize non-pro-rata distribution in your trust, and avoid post-distribution sibling buyouts.
• Fund the trust and leave written instructions that the one-year clock starts at death.
• Do not gift the home or add children to title during your life; both reassess and forfeit the stepped-up basis.
• Rentals and second homes cannot be protected, and even a qualifying home is capped at the base plus $1,044,586.
