    How to Transfer California Property Tax Base from Old Home to New

    Transfer California Property Tax Base

    One of the biggest advantages of owning a home in California is Proposition 13.  This limits how much your property taxes can go up each year. Many long-time homeowners are paying property taxes based on an assessed value that is often well below the current market value of their home. Giving up this tax advantage can make it tough to move in retirement.

    Proposition 19 gives you the advantage of potentially being able to transfer the lower Prop 13 tax base from your home to a new one if you move. Keep reading as we share how to transfer California property tax from the old home to the new.

    Today, we will answer the following question about Transferring Property Tax in California:

    “I’m over 55 and have owned my home in Southern California for decades. I’m looking to move to another home for my retirement. Will I be able to transfer my property tax base from my old home to my new home?”

    The short answer is, as it almost always is, “it depends.” Here is some additional information to help you figure out if you will be able to transfer your low base to a new home in California.

    Update On Prop 19 Transfer From The LA County Assessor (1/12/2026)

    I just received the following information from Jeffrey Prang, the Los Angeles County Assessor and thought you might find this information useful regarding Prop 19 Parent to child transfers:

    Proposition 19 remains one of the most consequential property tax reforms in recent years for intergenerational transfers.  Intergenerational transfers refer to transfers between parents and children and, in some cases, between grandparents and grandchildren.  To keep things simple, we will explore this Proposition 19 benefit as it applies to parent-to-child transfers.

    Under Proposition 19, a child who receives their parents’ principal residence, whether by inheritance or a deed transfer, may retain their parents’ tax base (in whole or in part).  While this benefit applies to a parent’s principal residence, it does not apply to other property they may own (vacation homes, income property, etc.).  As such, when property other than the parents’ home is transferred to their children, that property will be reassessed at market value.

    To qualify for this benefit, a child must occupy the home as their principal residence and file for the Homeowners’ Exemption within one year of the parent-child transfer.  The child must also file a Claim for Reassessment Exclusion for Transfer Between Parent and child Occurring on or After February 16, 2021 (Form BOE-19-P) within three years of the transfer or before the property is transferred to a third party, whichever occurs first, or within six months of the mailing date of the Notices of Supplemental and/or Escape Assessment issued in connection with the parent-child transfer.

    The Proposition 19 benefit is also subject to a value limit.  If the property’s market value at the time of the parent-child transfer is $1 million or less, the child can retain their parents’ tax base without adjustment; however, if the property’s market value at the time of the parent-child transfer is over $1 million, a value comparison test is applied to determine whether or not the parents’ tax base is required to be adjusted.

    Once a Proposition 19 exclusion has been approved, a child will retain their parents’ tax base only as long as they continue to occupy the home as their principal residence.  If they move out, the market value of the home as of the parent-child transfer date (adjusted by the Proposition 13 annual inflation factor of no more than 2%) will become the new tax base for the property.

    Transfer California Property Tax for Homeowners 55 and over.

    California homeowners 55 and older can get the opportunity to sell their primary residence and transfer the property tax assessment to a new home under Proposition 19 (and formerly Proposition 60). The caveat here is that the market value of the new house generally must be lower than or equal to the home being sold. For married couples, only one spouse must be 55 or older.

    This regulation was designed to help longtime homeowners in California who wanted to downsize in retirement and avoid having to give up their lower property tax assessments. I work with many clients who live in homes that are worth well north of 10 times what they paid for them. With sky-high real estate values in much of California, the tax savings here could be huge. For example, the difference can be between staying in your home and being forced to move.  Perhaps you want to move from your current home to a fabulous community like Palm Springs or Lake Arrowhead.

    Under the aforementioned Proposition 13, homes are only reassessed for property taxes when a change in ownership occurs or there is new construction. If neither of those actions occurred, the assessed tax base can only go up by an inflation rate not to exceed two percent per year. On a side note, homeowners can also get a temporary tax reduction when their property values decrease. Real estate does go down in value here in California, as much as people like to claim it doesn’t.

    With real estate values near record highs in much of California, most homeowners would face large property tax increases if they were to buy their homes again today.  They would likely even see tax increases if they were to downsize to a cheaper home.

    Proposition 60 gives homeowners a way to move or downsize without greatly increasing their tax bills. It’s important to note that there are restrictions in order to receive this generous benefit. Restrictions include the following:

    1. You must be 55 or older to transfer your current tax base to a new primary residence.
    2. The new home must also be in the same county as your current one. However, Proposition 90 allows for transfers of base-year values but only between the counties of Los Angeles, Orange, San Diego, San Mateo, Alameda, El Dorado, Santa Clara, and Ventura. These are subject to change, so make sure to check with your assessor before buying or selling a home.
    3. The new home must have been purchased within two years before or after the sale of the original, low-tax-based property. The portion before or after this will make it easier to account for when downsizing in retirement. Keep in mind that issues could arise if new and old homes are close in value. If the old home experiences a decrease in value and sells later, your new home may not meet the equal or lesser value requirement.

    Can I transfer the California Property Tax base if I buy and sell my old home, then buy a new one?

    There is a little added cushion for those who are buying their new homes after selling their current homes and who wish to transfer the tax base. If the new home was purchased within one year of selling the former home, the new home must be 105%, or less, than the value of the former home. If the new home was purchased between one and two years after selling the former home, the new home must be less than 110% of the former home’s sale price. Be aware of these deadlines when shopping for your dream home in retirement.

    There is a lot of confusion and misinformation about this tax break. This is something people can do once in their lifetime. Therefore, not many of your friends are likely to have gone through this. Also, the requirement to stay in the same county also deters some potential homeowners from benefiting from Proposition 60.

    Proposition 60 and Proposition 90 – The fine print on how to Transfer California Property Tax Base

    According to the Los Angeles County Office of the Assessor website, a claim must be filed within three years of purchasing or completing the new construction of the replacement property. If a claim is filed after the three-year period, relief will be granted beginning with the calendar year in which the claim was filed.

     

    If this is something that could potentially benefit you, apply to the Los Angeles County Office of the Assessor for a “Claim of Base Year Value Transfer.” Keep in mind that just because your old home sold for $2.5 million and your new home was $2.45 million, that doesn’t mean you will automatically have your application approved. The assessor can challenge whether the sales price equals the market value.

    If you sell your old home and throw in furniture or other items, your value may be challenged. This can extend to things that are often included in a home sale, like washers, dryers or above-ground spas. If your new home’s value exceeds the old home’s price by even one cent, you will lose out completely on the benefits of Proposition 60.  Make a note in your sales contract of the value being assigned to the personal property that’s being included with the sale of the home.

     

    Los Angeles County residents can visit the assessor’s website for more information. With Transfer California Property Tax being so valuable, you want to dot your I’s and cross your T’s.

    I would love to hear from anyone who has taken advantage of transferring their lower tax base. Or if you have been turned down attempting to use Prop 60 or 90.   Properly using these laws could be the difference between a secure retirement in California and struggling to get by.  Or even just being stuck in a home where you can’t get up or down the stairs.
