California Proposition 19 explained: property tax transfers and inherited homes

Before Proposition 19, base year value transfers were limited in how often and where they could be used, and a separate exclusion allowed parents to transfer property to children without reassessment in fairly broad circumstances.

Proposition 19 expanded the first and substantially narrowed the second. The base year value transfer provisions took effect April 1, 2021, and the changes to parent-child and grandparent-grandchild transfers took effect February 16, 2021.

If you are 55 or older, severely and permanently disabled, or your home was substantially damaged by wildfire or a declared disaster, Proposition 19 may allow you to transfer the taxable value of your existing primary residence to a replacement primary residence anywhere in California.

For the age-55 and disability categories, this can be used up to three times. If the replacement home costs more than the home you sold, the difference is generally added to the transferred taxable value rather than triggering a full reassessment. Timing requirements apply between the sale and the purchase, so plan the sequence deliberately.

This is the change that surprises families most often. Under Proposition 19, a parent-to-child transfer generally avoids reassessment only if the child uses the property as their own primary residence, and the property must be claimed as such within the required timeframe.

Even when the exclusion applies, it is limited. If the property's value exceeds the excluded amount by more than the allowed threshold, a portion is added to the assessed value. Property that an heir rents out or keeps as a second home generally does not qualify and is reassessed to current market value.

For families holding long-owned Southern California property with a low assessed value, this can represent a very large change in the annual tax bill, which is why the decision deserves professional advice well before it becomes urgent.

For a longtime homeowner over 55, the base year value transfer can change the arithmetic of moving substantially, because the ongoing property tax on a replacement home may be far lower than a new buyer would pay for the same property. That is worth modeling before deciding to stay put.

For families anticipating an inheritance, the practical question is whether an heir intends to live in the property. That single fact drives most of the tax outcome, and it is better addressed in advance than after the fact.

This guide is general information, not tax or legal advice. Proposition 19's requirements involve deadlines, value thresholds that adjust over time, and fact-specific determinations that only the county assessor can make for your property.

Before relying on any of this for a decision, confirm the current requirements with the county assessor for the property in question and consult a qualified tax professional or estate attorney. Andrew can help with the real estate side of a move and coordinate with the professionals advising you.
