You cannot avoid a reassessment entirely, but you can reduce the chance of triggering one

California's Proposition 13 (1978) froze property tax assessments at their 1975 value and limits annual increases to 2 percent — unless the property is sold or undergoes a "change in ownership." A reassessment happens when the county assessor determines that a change in ownership has occurred. The reassessment sets your property's new assessed value, which is usually much higher than your current one, and your taxes jump accordingly.

You cannot prevent reassessment if you sell the property or transfer it to someone outside a narrow list of family members. But you can structure transfers to family members in ways that keep the property off the reassessment list, and you can avoid common mistakes that trigger reassessments you did not intend.

Key Takeaways

  • Transfers to spouses, parents, children, and grandchildren are exempt from reassessment under California law, but only if you file the correct form with the county assessor within three years of the transfer.
  • Transfers to trusts, limited liability companies, or other entities can trigger reassessment even if the beneficial owner is a family member, unless the transfer meets strict requirements.
  • Adding a name to a deed as a joint tenant or changing how title is held can be treated as a change in ownership and cause reassessment.
  • The county assessor's office can initiate a reassessment based on a public record search, so you do not need to report the transfer yourself — but filing the exemption form stops the reassessment before it happens.
  • If reassessment occurs, you can file a Proposition 8 claim to reduce the assessed value if the market value has dropped, but this does not undo the reassessment itself.

Family transfers that avoid reassessment

California Revenue and Taxation Code Section 63.1 exempts certain transfers from reassessment. The exemption applies when you transfer property to or from a spouse, parent, child, or grandchild. The transfer must be direct — meaning the family member receives an ownership interest in the real property itself, not just a financial benefit.

To claim this exemption, you must file Form 60-A (Claim for Reassessment Exclusion for Family Transfers) with the county assessor's office in the county where the property is located. You have three years from the date of transfer to file. If you do not file within three years, the exemption is lost and the property will be reassessed at market value.

The form requires the original deed, proof of the family relationship (birth certificate, marriage certificate, or court order), and identification of both the transferor and transferee. Some counties accept electronic filing; others require a paper copy. Contact your county assessor's office to confirm their process and deadline.

Transfers to trusts and entities that may trigger reassessment

Placing property into a revocable living trust during your lifetime is generally not treated as a change in ownership, because you retain control and beneficial interest. However, transferring property into an irrevocable trust, a limited liability company (LLC), a partnership, or a corporation can trigger reassessment, even if you are the sole member or owner.

The key test is whether the transfer results in a change in the "proportional ownership interest" or "control" of the property. If you transfer property to an LLC that you own 100 percent, the assessor may still treat it as a change in ownership because the property is now held in a different legal entity. If you later add a partner or member to the LLC, a second reassessment can occur.

If you must transfer property into an entity for business or liability reasons, file Form 60-A or a letter of explanation with the assessor before or immediately after the transfer, documenting that no change in beneficial ownership has occurred. This does not may provide the assessor will agree, but it creates a record and may delay or prevent reassessment. Consult a tax attorney or accountant before transferring property to an entity.

Adding names to a deed and joint tenancy changes

Adding a spouse's name to a deed as a joint tenant is usually exempt from reassessment under the family transfer rule, provided you file Form 60-A. However, adding anyone else's name — a child, a business partner, a friend — can be treated as a change in ownership because you are reducing your proportional ownership interest.

Similarly, converting property from sole ownership to joint tenancy with a non-spouse, or changing from joint tenancy to tenancy in common, can trigger reassessment. Even if the other person contributes no money and receives no benefit, the change in how title is held may be enough to cause the assessor to reassess.

If you need to add a name to a deed for any reason other than a spouse, consult the assessor's office first. Ask in writing whether the change will trigger reassessment, and request a written response. This gives you a record of the assessor's position before you proceed.

How the assessor finds out about transfers

You do not have to report a transfer to the assessor. The county assessor's office monitors recorded deeds through the county recorder's office. When a new deed is recorded, the assessor's staff reviews it to determine whether a change in ownership has occurred. This process can take weeks or months, but it is automatic.

If the assessor determines that a change in ownership has occurred, they will mail you a Notice of Reassessment or a Preliminary Change of Ownership Report (PCOR). The notice will state the new assessed value and the effective date of the reassessment. You then have the right to file a written protest or a Proposition 8 claim if you believe the value is incorrect.

Filing the exemption form (Form 60-A) before the assessor issues a reassessment notice is the most effective way to prevent reassessment. Once a reassessment notice is issued, you can still file the exemption form, but the burden shifts to you to prove the transfer qualifies for the exemption.

Proposition 8 claims after reassessment

If your property has been reassessed and you believe the new assessed value exceeds the current market value, you can file a Proposition 8 claim to reduce the assessed value. This is not the same as avoiding reassessment — the reassessment still stands, but the assessed value may be lowered.

Proposition 8 claims are filed with the county assessor or the county assessment appeals board, depending on the county. You must file within 30 days of receiving the reassessment notice, or you lose the right to appeal that year. The claim requires evidence of the property's current market value, such as recent appraisals, comparable sales, or a professional valuation.

Proposition 8 claims are most useful when the real estate market has declined and your property's market value is lower than the reassessed value. If the market is stable or rising, the assessor is unlikely to reduce the value below what they believe is current market value.

Common mistakes that trigger unwanted reassessments

Failing to file Form 60-A within three years of a family transfer is the most common mistake. Even if the transfer was exempt, the exemption is lost if you do not file the form in time. The reassessment then becomes permanent unless you can prove the transfer was exempt and file a late claim with supporting evidence.

A second common mistake is transferring property to a trust or entity without understanding that the assessor may treat it as a change in ownership. Many people create trusts for estate planning or liability reasons without realizing the tax consequence. If you are considering such a transfer, consult a tax professional first.

A third mistake is adding a name to a deed without filing an exemption form or asking the assessor whether the change will trigger reassessment. Even if the addition is intended to be temporary or informal, the recorded deed is what matters to the assessor.

Frequently Asked Questions

If I transfer property to my child, do I have to file Form 60-A or will the assessor know it is exempt?

You must file Form 60-A yourself. The assessor will not automatically know the transfer is exempt based on the deed alone. If you do not file within three years, the assessor will reassess the property at market value, and you will lose the exemption. File the form as soon as possible after the transfer.

What if I recorded a deed transferring property to my spouse five years ago and never filed Form 60-A?

The three-year window has closed, and you have likely lost the exemption. However, you can still file a late claim with the assessor or the assessment appeals board, along with evidence that the transfer was to a spouse and that you did not intend to trigger reassessment. Success is not may provide, but it is worth attempting.

Does putting property into a revocable living trust trigger reassessment?

No. A revocable living trust is not treated as a change in ownership because you retain full control and beneficial interest during your lifetime. However, when you die and the trust transfers the property to your heirs, that transfer may trigger reassessment unless it qualifies for the family transfer exemption.

If my property was reassessed, can I get the old tax rate back?

No. Once reassessment occurs, the new assessed value becomes the base for future 2 percent annual increases. You cannot undo the reassessment itself. You can only file a Proposition 8 claim to reduce the assessed value if you believe it exceeds current market value, but this does not restore the old rate.

Do I need a lawyer to file Form 60-A?

No. Form 60-A is a straightforward form that you can file yourself. However, if the transfer is complex, if you missed the three-year deadline, or if the assessor has already issued a reassessment notice, consulting a tax attorney or accountant may be worthwhile to protect your interests.
