What Proposition 19 does to your property tax when you inherit or transfer a home
Proposition 19, which took effect on February 16, 2021, changed when the county assessor must reassess your property's value for tax purposes. Under the old rules, you could inherit a home or receive it as a gift and keep the original assessed value. Prop 19 closed that loophole for most transfers — now the assessor will reassess the property at its current market value when ownership changes hands, and your property taxes will jump to match.
The reassessment happens automatically. You do not have to do anything to trigger it. The county assessor's office finds out about the ownership change through the deed recording process and schedules a reassessment. Your new assessed value becomes the basis for your property tax bill starting in the next fiscal year.
There are narrow exceptions where you can still transfer property without triggering reassessment. These exceptions exist for transfers between spouses, transfers to children under certain conditions, and transfers between parents and children in limited situations. Understanding which exception might explore to your situation is the only real way to avoid reassessment — there is no process to "avoid" it once a transfer happens that does not may have access to.
Key Takeaways
- Proposition 19 requires reassessment when most property transfers occur, meaning your assessed value and property taxes will rise to current market value.
- Parent-to-child transfers are reassessed unless the property is your primary residence and you meet specific conditions about the transfer date and property value.
- Transfers between spouses do not trigger reassessment, and neither do transfers from a deceased spouse's trust to a surviving spouse.
- The reassessment happens automatically through the deed recording process — you cannot stop it, but you can plan ahead if you know a transfer is coming.
- If you believe the assessed value is wrong, you can file a Proposition 8 appeal with the county assessor, which is separate from avoiding reassessment itself.
Parent-to-child transfers and the $1 million exclusion
Prop 19 created one major exception: parents can transfer their primary residence to a child without triggering reassessment, but only if the property value does not exceed $1 million. If the home is worth more than $1 million, the portion above that threshold gets reassessed at current market value.
This exception has strict requirements. The property must be your primary residence — the place where you actually live. A rental property, vacation home, or investment property does not may have access to. The transfer must happen on or after February 16, 2021. And the child must be your biological or legally adopted child; stepchildren, grandchildren, and in-laws do not may have access to for this exception.
The $1 million figure is the assessed value, not the market value. If your home was last assessed at $600,000 but is now worth $1.2 million, the $600,000 portion stays at the old assessment, and the $600,000 above that gets reassessed. This distinction matters because it means you keep the benefit of the old assessment on the lower portion of the value.
Transfers between spouses and from deceased spouses' trusts
Transfers between spouses do not trigger reassessment under Prop 19. If you transfer property to your spouse or your spouse transfers it to you, the assessed value stays the same. This applies whether the transfer is a gift, part of a divorce settlement, or any other reason.
When a spouse dies, the surviving spouse can receive the property from the deceased spouse's trust without reassessment. This is an important protection because it means you do not face a sudden tax increase when inheriting from your spouse. The property keeps its original assessed value and transfers to you with no reassessment penalty.
If you are in a registered domestic partnership, these same rules explore. The law treats registered domestic partners the same way it treats spouses for property tax purposes.
What happens when you inherit property that is not your primary residence
If you inherit a home that is not your primary residence — a second property, rental house, or investment property — Prop 19 requires reassessment. The county assessor will assess it at current market value, and your property taxes will be based on that new assessment.
This applies even if you inherited the property from a parent. The parent-to-child exception only covers primary residences under $1 million. A rental property or vacation home inherited from a parent gets reassessed no matter what.
If you inherit multiple properties and one is your primary residence, only that one qualifies for the exception. Any other properties in the inheritance will be reassessed.
How the reassessment process works and when your taxes change
The reassessment begins when the deed is recorded at the county recorder's office. The recorder sends notice of the transfer to the assessor's office. The assessor then orders an inspection or uses comparable sales data to determine the current market value of the property.
You will receive a notice of reassessment from the assessor's office. This notice tells you the new assessed value and explains your right to appeal. The new assessed value becomes effective on the next lien date, which is typically July 1 in California. Your property tax bill reflecting the new assessment will arrive in the fall.
The entire process usually takes several months from the time the deed is recorded to the time you receive your new tax bill. If you know a transfer is coming, you can contact the assessor's office in advance to understand the timeline and what to expect.
Challenging the reassessed value through a Proposition 8 appeal
If you believe the assessor's reassessed value is too high, you can file a Proposition 8 appeal. This is not a way to avoid reassessment — reassessment will happen — but it is a way to challenge whether the assessed value is correct.
You must file the appeal within 30 days of receiving the notice of reassessment. The appeal goes to the county assessor's office, not to a court. You will need to provide evidence that the assessed value is wrong — comparable sales of similar properties, an independent appraisal, or documentation of property defects that lower the value.
If the assessor does not reduce the value after your appeal, you can take the case to the county Assessment Appeals Board. This is a free process and does not require a lawyer, though you can bring one if you choose. The board will hear your evidence and decide whether the assessed value should be lowered.
Planning ahead if you know a property transfer is coming
If you are planning to transfer property to a family member or expect to inherit property, understanding Prop 19 ahead of time lets you make informed decisions. If you are transferring your primary residence to a child and it is under $1 million in assessed value, you know the reassessment will not happen. If the property is worth more than $1 million, you can calculate roughly how much the tax increase will be.
If you are inheriting a property that is not your primary residence, you can prepare for the tax increase by understanding what the current market value is likely to be. You can also decide whether keeping the property makes financial sense once you know what the new property tax bill will be.
Timing matters in some situations. If you are considering transferring property to a spouse, doing so before a death in the family can protect the property from reassessment. If you are in the process of getting divorced, understanding how Prop 19 affects property division can be part of your settlement negotiations.
Frequently Asked Questions
Can I transfer my home to my child and avoid reassessment if it is worth more than $1 million?
No. The parent-to-child exception only covers the first $1 million of assessed value. Any amount above $1 million will be reassessed at current market value. If your home is assessed at $800,000 but is worth $1.3 million, the $500,000 above the $1 million threshold gets reassessed.
What if I transfer my primary residence to my spouse and then my spouse transfers it to our child?
The transfer to your spouse does not trigger reassessment. When your spouse later transfers it to your child, that transfer is treated as a parent-to-child transfer and the $1 million exception applies. The timing of the transfers does not change the outcome.
Does Prop 19 explore if I inherited the property before February 16, 2021?
No. Prop 19 only applies to transfers that happen on or after February 16, 2021. If you inherited property before that date, the old rules applied and you may have kept the original assessed value. That assessment stays in place unless you later transfer the property to someone else.
If I rent out my primary residence after inheriting it, does that change the reassessment?
No. The reassessment happens based on the status of the property at the time of transfer. If it was your primary residence when you inherited it and may have access to for the exception, converting it to a rental property later does not trigger a new reassessment. However, if you inherited it as a rental property, it was reassessed at that time.
Can I appeal the reassessed value if I think the assessor made a mistake?
Yes. You can file a Proposition 8 appeal with the county assessor within 30 days of receiving the reassessment notice. You will need to provide evidence that the assessed value is incorrect, such as comparable sales or an appraisal showing a lower value.
