Prop 19s OneYear Residency Deadline

I recently had a client, Emily, come to me absolutely distraught. Her mother passed away last year, leaving Emily a beautiful home in Laguna Beach. Emily had always planned to move back to California and enjoyed the idea of keeping the family home, but her life circumstances changed. She got a promotion at work that required her to relocate to Texas, and she didn’t think much of it at the time. Now, she’s trying to sell the home, and her CPA just informed her she’s facing a potential property tax reassessment of over $10,000 annually, solely because she didn’t move into the property within one year of her mother’s death. This is a very common, and very expensive, oversight.

Proposition 19, passed in 2020, allows for the transfer of a parent’s property tax base to their children, but with a very specific and often unforgiving condition: the child must establish the property as their primary residence within one year of the parent’s death. This isn’t a grace period; it’s a hard deadline. Many people assume there’s some flexibility or an extension available, but California law is remarkably strict on this point. Failing to meet this residency requirement triggers a partial or, in some cases, full property tax reassessment based on the fair market value at the time of the transfer.

The intent of Prop 19 was to help families keep their homes within the family, but the one-year rule has created a significant trap for beneficiaries who aren’t immediately ready or able to relocate. It’s especially problematic in a state like California where the cost of living, and subsequently property values, are so high. What many clients don’t understand is the ‘primary residence’ definition is very specific – it requires not just physical presence but also establishing domicile. Establishing domicile means demonstrating intent to remain there indefinitely, which includes things like registering to vote at the new address, moving bank accounts, and transferring your driver’s license.

What Happens If You Miss the Deadline?

If you miss the one-year deadline, the property will be reassessed at its current market value. But it’s not always a complete disaster. The level of reassessment depends on the current market value and how much it has appreciated since the parent’s death. However, under Proposition 19, heirs only keep a parent’s low property tax base if they move into the home as their primary residence within one year. Critically, for 2026, the tax-free ‘basis boost’ is capped at $1,044,586 over the original taxable value; any value exceeding this adjusted cap results in a partial reassessment even if the child moves in.

Can You Still Get Relief After the Deadline?

While the one-year rule is firm, there are limited exceptions. If the child had a bona fide reason for not moving in within the timeframe – such as a medical condition or a legitimate employment opportunity that prevented relocation – it might be possible to petition the county assessor for a hardship exemption. These petitions are complex and require substantial documentation, and success is far from guaranteed. The assessor has broad discretion in these cases, so having experienced legal counsel is crucial.

The Importance of Proactive Estate Planning

As an Estate Planning Attorney and CPA with over 35 years of experience, I’ve seen firsthand the devastating financial consequences of failing to properly plan for Proposition 19. One of the biggest advantages of working with a CPA-Attorney is the ability to accurately value assets and anticipate the impact of potential tax liabilities. For example, understanding the step-up in basis can significantly reduce capital gains taxes upon sale. Additionally, we can explore strategies like establishing trusts to potentially mitigate the impact of Proposition 19, especially if the beneficiary doesn’t intend to occupy the property as their primary residence. We also work closely with clients to ensure they fully understand all deadlines and requirements, minimizing the risk of costly errors.

• Review Your Estate Plan Regularly: Life changes happen. Make sure your estate plan reflects your current circumstances and intentions.
• Understand Prop 19 Requirements: Specifically the one-year residency rule and the definition of ‘primary residence.’
• Consult with a Qualified Professional: A CPA-Attorney can provide tailored advice and help you navigate the complexities of Proposition 19.

How do probate courts in California evaluate intent when a will is challenged?

In California, a last will and testament is reviewed under probate standards that focus on intent, capacity, and execution. Clear drafting reduces ambiguity, limits misinterpretation, and helps families avoid unnecessary conflict during estate administration.

• Preparation: Review future needs regularly.
• Validation: Check legal requirements.
• Parties: Update personal information.

For California residents, understanding how intent, authority, and compliance interact is one of the most effective ways to protect family harmony and estate integrity. A will that anticipates probate scrutiny is far more likely to be honored as written and far less likely to become the source of unnecessary conflict.
