Transfer Property Tax When Selling for Seniors 55 and older under Prop 60 and Prop 90

How to Transfer Your Lower Property Tax When Selling for Seniors 55 and older under Prop 60 and Prop 90

Did you know that if you are 55 and over, under certain conditions of Propositions 60 and 90, you may be able to transfer your existing primary residence’s factored base year value to a replacement home that is of lesser or equal value than your existing home? Basically, the current house that you are selling should be of equal or greater value than the new house that you are buying. Prop 60 and 90 provide property tax savings to California seniors who are 55 and older who are considering to move, downsize, sell their home and buy a new home while keeping their lower property tax base. There are 11 counties in California including San Diego County who currently participate and provide these property tax savings to seniors. Read more information on Prop 60/90 on section 69.5 of the Revenue and Taxation Code.

Seniors may transfer their property Tax base on a primary residence in California under Propositions 60 and 90

Propositions 60 and 90 may result in substantial tax savings for seniors 55 and older as it allows the adjusted base year value of the original (sold) property to be transferred to the newly purchased or constructed home if eligibility requirements are met with some exceptions. A transfer of the lower property tax base may only be done once and the homeowner must buy and sell within two years.
Important Dates to Remember for Prop 60 & Prop 90
  • the date the original property is sold
  • the date the replacement dwelling is purchased
  • if the replacement home is a new construction, the date the new construction of the replacement home is completed.

Age Requirement for selling your home: You must be at least 55 years old when your original property (primary residence) sells.

What is the difference between Proposition 60 and Proposition 90?

Proposition 60 allows transfers of base year values within the same county (intra-county). For example, seniors who sell their primary residence in San Diego County and relocate and buy in another in the same county may receive these property tax savings.
Proposition 90 allows transfers from one county to another county in California (inter-county) and it is the discretion of each county to authorize such transfers.

Frequently Asked Questions


What are the eligibility requirements to take advantage of the tax savings for seniors under Propositions 60/90?

  1. You, or a spouse residing with you, must have been at least 55 years of age when the original property was sold.
  2. The replacement property must be your principal residence and must be eligible for the homeowners’ exemption or disabled veterans’ exemption.
  3. The replacement property must be of equal or lesser “current market value” than the original property. The “equal or lesser” test is applied to the entire replacement property, even if the owner of the original property purchases only a partial interest in the replacement property. Owners of two qualifying original properties may not combine the values of those properties in order to qualify for a Proposition 60 base-year value transfer to a replacement property of greater value than the more valuable of the two original properties.
  4. The replacement property must be purchased or built within two years (before or after) of the sale of the original property.
  5. To receive retroactive relief from the date of transfer, you must file your claim within three years following the purchase date or new construction completion date of the replacement property.
  6. Your original property must have been eligible for the homeowners’ or disabled veterans’ exemption either at the time it was sold or within two years of the purchase or construction of the replacement property.
The original property (the home you have sold) must be subject to reappraisal at its current fair market value at the time of sale, unless the buyer(s) of your original property also qualify the property as a replacement property for a base year value transfer due to disaster relief or a base year value transfer for a severely and permanently disabled person*. Therefore, most transfers between parents and children will not qualify. * Section 69.5 also sets forth the provisions of Proposition 110 which allows the transfer of a base year value for severely and permanently disabled persons. Except for the disability factor, the qualifications for Propositions 60/90 are same as Proposition 110.

How many times can seniors transfer their property tax base under Prop 60/90?

Proposition 60/90 may only be used one-time only. Once you have filed and received this property tax relief as a senior 55 and older, neither you nor your spouse who resides with you can ever file again, even upon your spouse’s death or if the two of you divorce. You can transfer your property tax more than once after being qualified because of age (55 and older), only if you become disabled. This would require a a different claim form.

What type of properties can seniors buy under Proposition 60/90 to be eligible for the property tax savings?

Property tax relief for seniors may be granted for a single family residence, condominium, unit in planned development, cooperative housing, community apartment, manufactured home subject to local real property tax, or living unit within a larger structure consisting of both residential and non-residential accommodations.

How do seniors 55 and older file for Proposition 60/90 tax relief?

This property tax senior relief is not automatic. After selling your existing home and buying a replacement home in one of the participating counties in California, an application must be filed with the county assessor where the replacement property is located. The claim form, BOE-60-AH, Claim of Person(s) at Least 55 Years of Age for Transfer of Base Year Value to Replacement Dwelling, may be obtained from the assessor’s office.
What is the legislation behind Proposition 60 & 90?
Section 69.5 was added to the Revenue and Taxation Code1 in 1987 to implement Proposition 60, which amended section 2 of article XIII A of the California Constitution to authorize the Legislature to provide for the transfer of a base year value from a principal residence2 to a replacement dwelling within the same county by a homeowner age 55 and over.”
“Subsequently, section 69.5 was amended to implement Proposition 90, which authorized county boards of supervisors to adopt ordinances allowing base year value transfers between different counties, and Proposition 110, which extended these provisions to severely and permanently disabled persons of any age.”
If you are completing a short sale in San Diego, you will still be eligible for Prop 60 or 90 if purchasing another home after your short sale, as long as it is within the allocated time.
