Property tax foreclosure in California

California is a tax deed state. If your property taxes go unpaid, the home becomes tax-defaulted on July 1, and after five years in default the county tax collector gets the power to sell it at a public auction. You can stop the sale by paying everything owed up to the close of business on the last business day before the auction. If the home sells for more than the taxes and costs, you can claim the extra money, called excess proceeds, from the county within one year after the tax deed is recorded.

The property tax process in California, step by step

  1. Taxes become delinquent

    December 10 and April 10

    The first installment of your property tax bill is delinquent after 5 p.m. on December 10, and the second after 5 p.m. on April 10. A 10 percent penalty is added to each late installment, and after the second installment is late the county can add a cost charge of up to $55.

    Cal. Rev. & Tax. Code §§ 2617, 2618, 2621

  2. The home becomes tax-defaulted

    July 1 after the tax year

    Taxes still unpaid at 12:01 a.m. on July 1 are declared in default by law. From then on, redemption penalties of 1.5 percent per month are added, plus a $15 redemption fee. You still own the home and can pay off the full amount at any time before the sale.

    Cal. Rev. & Tax. Code §§ 3436, 4102, 4103

  3. Ask about an installment plan

    Before the county gets the power to sell

    You can choose to pay defaulted taxes in installments if you start before 5 p.m. on the last business day before the tax collector gets the power to sell. The county may charge a set-up fee. If you miss a required payment, the plan ends and you may not be allowed to start a new one, so ask the tax collector for the exact terms in writing.

    Cal. Rev. & Tax. Code § 4217

  4. Power to sell after five years

    5 years after default

    Five years after a home becomes tax-defaulted, the tax collector has the power to sell it and must try to sell it. The period is three years for nonresidential commercial property, and it can be paused for homes damaged in a declared disaster and not yet repaired.

    Cal. Rev. & Tax. Code § 3691

  5. Notices before the auction

    45 to 120 days before the sale

    The tax collector must send you a notice by certified mail 45 to 120 days before the sale with the date, the amount needed to redeem, and your right to claim excess proceeds. The notice is also published for three weeks. If the home is your primary residence, the county must try to contact you in person 10 to 120 days before the sale.

    Cal. Rev. & Tax. Code §§ 3701, 3702, 3704.7

  6. Last day to redeem and the tax deed

    Close of business, last business day before the sale

    Your right to redeem ends at the close of business on the last business day before the auction starts, and a payment sent by mail must arrive before then. If the home sells, the buyer gets a tax deed that wipes out most liens, including mortgages. If you still live there, get legal help right away.

    Cal. Rev. & Tax. Code §§ 3707, 3712

  7. Claim the excess proceeds

    Within 1 year after the tax deed is recorded

    If the sale brings in more than $150 over the taxes and costs, the county must mail notice of your right to claim it within 90 days after the sale. File your claim with the county so it is postmarked within one year after the tax deed is recorded. Lienholders of record are paid first, then former owners, and money no one claims in time can go to the county general fund.

    Cal. Rev. & Tax. Code §§ 4674, 4675, 4676

Common questions in California

How long can I go without paying property taxes in California before the county can sell my home?

The home becomes tax-defaulted on July 1 after the tax year, and the county gets the power to sell five years later. Penalties of 1.5 percent per month build up during that time, so the amount needed to save the home keeps growing. You can pay in full or start an installment plan before the power to sell begins.

Can the county sell my tax-defaulted home to a city or nonprofit instead of at auction?

Yes. A county can sell tax-defaulted property by agreement to a public agency or a qualified nonprofit, which is called a Chapter 8 sale. Since a 2025 law, the board of supervisors must first hold a hearing, mail you notice at least 45 days ahead, and find that the price is at least the property's tax sale value or that there would be no excess proceeds anyway. You can ask a court to review the decision within 45 days.

Is there help for seniors who cannot pay California property taxes?

The State Controller's Property Tax Postponement Program lets homeowners who are seniors, blind or disabled put off current-year taxes on their main home if they have at least 40 percent equity and household income of $57,002 or less, among other rules. For 2026-27 the filing period runs October 1, 2026 to February 10, 2027. The postponed taxes become a lien that must be repaid.

What happens if I miss the one-year deadline to claim excess proceeds?

The law sets a firm one-year deadline after the tax deed is recorded, and San Diego County's page says there are no exceptions. After that, the county may move unclaimed excess proceeds into its general fund. Watch your mail after a tax sale and file early.
