Prop 13 and Prop 19: Keeping Your Low Tax Bill Through a Divorce

Prop 13 in one paragraph

Since 1978, California assesses property tax on the purchase price, not on current market value. That base-year value can rise at most about 2% a year, and the general tax rate is capped at 1% of assessed value (plus local voter-approved bonds and assessments). The result: a homeowner who bought in Huntington Beach or Long Beach in 1998 often pays tax on a fraction of what a neighbor who bought last year pays.

Divorce doesn't break Prop 13 — the interspousal exclusion

A change in ownership normally triggers reassessment to market value. But transfers between spouses are excluded — including transfers made to carry out a property settlement or decree of dissolution. In practice that means:

• A buyout keeps the base. When one spouse deeds their half to the other as part of the settlement, the home's assessed value generally stays where it was.
• A refinance doesn't reassess either. Changing the loan doesn't change ownership for assessment purposes.
• Timing matters less than documentation. The transfer should be clearly "in connection with" the dissolution — reference the case in the deed and keep the settlement handy.

Prop 19 — the gray-divorce superpower

Divorce after 50 is the fastest-growing segment of divorce in America. Many of those homeowners are sitting on a decades-old tax base and assume a sale means losing it. Since April 2021, Proposition 19 generally lets homeowners who are 55 or older, severely disabled, or victims of a wildfire or natural disaster transfer their base-year value to a replacement home anywhere in California — up to three times in a lifetime.

• The replacement home can be anywhere in the state — not just the same county.
• It can be more expensive; the difference is added to the transferred base rather than resetting it entirely.
• The replacement must generally be purchased or built within two years of the sale.
• Each spouse who qualifies may have their own opportunity after the divorce — confirm with the assessor how the "three times" count applies to each of you.

Selling in a divorce at 55+ doesn't have to mean losing your 1998 tax bill. It does mean sequencing the sale, the replacement purchase, and the claim form correctly — which is where a broker who also originates the financing can keep all three on one calendar.

Prop 19 caution — deeding the home to children

The same measure narrowed the parent-child exclusion effective February 16, 2021. A home transferred to a child now generally keeps its low base only if the child makes it their primary residence and files a homeowner's exemption, and only up to a value limit above the old base. If a settlement contemplates deeding the family home to an adult child — as a way to keep it "in the family" — the property-tax result may be very different from what it would have been before 2021.

How this fits the three paths

• Sell & Split — the buyer gets a new base; if you're 55+, you may carry yours to the next home under Prop 19.
• Buyout — interspousal exclusion keeps the base in place; refinance doesn't disturb it.
• Defer & Co-Own — nothing changes until the later sale; plan the Prop 19 claim for that date.

Property-tax outcomes depend on filing the correct assessor forms and on timing. This page is general education, not legal or tax advice. Consult the county assessor and a tax professional before relying on any exclusion.
