Since 2021, California heirs who don't move into an inherited home usually lose the old low property-tax base. Here's what that actually means for your bill.

If you've inherited a California home, Proposition 19 is the single rule most likely to surprise you — and it's why so many inherited California homes now get sold rather than held. Here's the plain version.
Before Prop 19, a child could inherit a parent's home and keep the parent's old, low property-tax assessment — sometimes a tax base set decades ago. Prop 19 (effective February 16, 2021) eliminated that parent-child exclusion for any inherited home the heir does NOT make their own primary residence within one year.
If you inherit the home and rent it, hold it vacant, or use it as a second home, the county reassesses it to current market value — which can raise the annual property-tax bill dramatically over what your parent paid. For a home that appreciated over decades, that jump is often the deciding factor between keeping and selling.
Don't confuse it with capital gains. When you sell, stepped-up basis still resets your cost basis to the date-of-death value, so a prompt sale usually triggers little capital-gains tax. Prop 19 is about the ongoing annual property tax while you HOLD the home — a separate question from what you owe when you sell.
This is general information, not tax advice, and the value caps and mechanics are specific. For a California inherited home, a quick check with a tax professional on your exact numbers is well worth it — we can point you to one, free.
Moving in as your primary residence within a year can preserve part of the low tax base, subject to a value cap. Not moving in means reassessment to current market value.
No — that's stepped-up basis, a separate federal rule. Prop 19 governs the ongoing California property-tax assessment while you own it.
