Transferring your property tax base in California can be a complex process, but it’s a topic of great interest for homeowners in the state. Proposition 13, a landmark property tax law passed in 1978, significantly impacted property tax assessments and the way they are transferred. Understanding this process is crucial, whether you’re a new homeowner, planning to move, or inherit property in California. In this comprehensive guide, we’ll delve into the intricacies of transferring property tax bases in California, ensuring that you have all the information you need to navigate this complex system successfully.

What is Proposition 13?

Before we dive into property tax base transfers, it’s essential to understand the foundation of California’s property tax system – Proposition 13. This landmark law was passed by California voters in 1978 and introduced a set of rules that significantly impacted property taxes in the state. Proposition 13 consists of three fundamental components:

  1. Property Tax Rate Limitation: It capped the property tax rate at 1% of the property’s assessed value at the time of acquisition.
  2. Assessment Value Limitation: It limited annual increases in assessed property values to a maximum of 2% per year. This means your property’s assessed value can only increase by a maximum of 2% annually, regardless of its actual market value.
  3. Transferring Property Tax Base: Proposition 13 introduced provisions for transferring the base-year value of a property to a new one under specific circumstances.

When Can You Transfer Your Property Tax Base?

Transferring your property tax base in California is only possible under certain circumstances. These include:

  1. Home Purchase: If you sell your current home and buy a new one in California, you may be able to transfer your current property’s assessed value to your new property. This applies if the new property is of equal or lesser value and is located in the same county.
  2. Age 55 or Older: Proposition 60 and 90 are constitutional amendments that allow homeowners age 55 or older to transfer their property tax base when purchasing a new home. These rules, however, come with specific conditions. In the case of Proposition 60, the new home must be in the same county as the old one, while Proposition 90 allows for inter-county transfers.
  3. Disaster Relief: If your home is severely damaged or destroyed by a natural disaster, you may be able to transfer your property tax base to a replacement property. This provision is aimed at providing relief to homeowners in times of crisis.
  4. Family Transfers: In cases of specific family transfers, such as parent-child or grandparent-grandchild transfers, the property tax base can be transferred without reassessment. This keeps the property taxes at the same rate for the new owners.

Proposition 19: A Game-Changer

One significant development in the realm of property tax transfers in California is Proposition 19. This proposition, passed in the November 2020 election, made several changes to the existing property tax rules. While it limited some aspects of property tax transfers, it also expanded certain provisions. Here are some key points about Proposition 19:

  1. Limitation on Parent-Child Transfers: Proposition 19 restricted the parent-child transfer exclusion. It now applies only to transfers of the primary residence and up to $1 million of assessed value for other real property.
  2. New Rules for Grandparent-Grandchild Transfers: Proposition 19 made it easier for grandchildren to benefit from the grandparent-grandchild transfer exclusion. Now, it’s possible to transfer a primary residence’s assessed value to a grandchild, subject to certain conditions.
  3. Changes in Seniors’ Property Tax Benefits: For homeowners over 55, Proposition 19 expanded the ability to transfer their property tax base, regardless of the new property’s location in California. However, this exclusion only applies to primary residences.

The Mechanics of Transferring Your Property Tax Base

Transferring your property tax base can be a complicated process, involving multiple forms and filings. Here is an overview of the steps involved:

  1. File a Claim: To initiate the transfer process, you must file a claim with your local county assessor’s office. This claim should outline your eligibility and the circumstances of the transfer.
  2. Provide Documentation: You will need to provide documentation that supports your claim, such as proof of your age, a copy of your sales contract, and other relevant paperwork.
  3. Comply with Deadlines: It’s crucial to adhere to specific deadlines outlined by your county assessor’s office. Failing to meet these deadlines can result in the denial of your claim.
  4. Complete Forms: You’ll need to fill out various forms depending on the type of transfer you’re seeking. These forms are typically available on your county assessor’s website or in their office.
  5. Pay Fees: There might be associated fees with the transfer process, depending on your situation. Be prepared to cover these costs.
  6. Wait for Approval: Once your claim is submitted, it will be reviewed by the county assessor’s office. If approved, your property tax base can be transferred to your new property.


Transferring your property tax base in California can be a complex process, but it’s essential to navigate it correctly to save on property taxes. Proposition 13, Proposition 60, Proposition 90, and Proposition 19 all play crucial roles in determining when and how you can transfer your property tax base. It’s crucial to understand the specific rules and provisions that apply to your situation and comply with the necessary paperwork and deadlines.

Remember, the rules surrounding property tax transfers can change, so it’s essential to stay updated with the latest legislation and consult with a tax professional or your local county assessor’s office for personalized guidance. By following the proper procedures, you can take advantage of California’s property tax laws to make your homeownership experience more manageable and cost-effective.
