When a California property owner dies, the county assessor needs to be told. The form is the Change in Ownership Statement — Death of Real Property Owner, BOE-502-D, and almost nobody hears about it until something has already gone sideways.
When it is due
Where there is no probate, the form is due within 150 days of the date of death. That includes property held in a living trust — in fact especially trust-held property, because the whole point of the trust was to avoid probate, and so nothing else prompts the filing.
Where the estate is probated, the statement is filed with the inventory and appraisal instead, and the 150-day clock is not the operative one.
The penalty does not trigger on day 150
This is the part that is misreported constantly. Passing day 150 without filing does not itself impose a penalty. The penalty under §482 is triggered 90 days after the assessor mails a written request for the statement.
So the sequence is: the deadline passes, the assessor eventually notices and sends a request, and then a 90-day clock starts that carries a real consequence.
The penalty itself is $100, or 10% of the taxes on the new base year value, whichever is greater — capped at $5,000 where the property has the homeowners’ exemption, and $20,000 where it does not.
The penalty is not the real exposure
The number that should concern a trustee is not the penalty. It is escape assessments, which reach back eight assessment rolls under §532(b)(2).
If a change in ownership went unreported and the county later discovers it, they can reassess retroactively and bill for the difference across as many as eight years. A $5,000 penalty cap sounds survivable. Eight years of back taxes on a reassessed Bay Area property is a different order of magnitude, and it typically surfaces at the worst possible moment — during escrow, when the title company runs its search.
Do not confuse it with the other two forms
There are three similarly-numbered forms and they do different jobs:
- BOE-502-D — Change in Ownership Statement, Death of Real Property Owner. 150 days where there is no probate.
- BOE-502-A — the Preliminary Change of Ownership Report, the PCOR. Filed at recording. Omitting it costs $20.
- BOE-502-AH — the full Change in Ownership Statement, due within 90 days.
People routinely believe that because the PCOR was handled at recording, the assessor has what it needs. It is a different form with a different job.
What to do about it
If you are a successor trustee or an heir and the death was recent, file it. It is a short form, it costs nothing, and it starts the clock on the county doing its assessment correctly rather than retroactively.
If the death was a while ago and this is the first you are hearing of it, that is common and it is fixable — but it is worth getting in front of rather than discovering during escrow. Bring it to the attorney handling the estate, or to the assessor directly.
And if a Prop 19 parent-to-child exclusion is in play, the assessor filing and the exclusion claim are separate submissions with separate deadlines — the occupancy and filing clocks on that are a different post entirely.
Every one of these dates, calculated from an actual date of death and exportable to your calendar, is what the deadline clock is for.
