If the County of San Diego sold your property through its tax-defaulted property auction, you have one year from the date the Tax Deed is recorded to file a claim for any proceeds over what the County, and lienholders, were owed and the costs of the sale.

There are no exceptions to this one-year time period. This article will explain how the County processes these sales, who is paid first, and what forms are used to make a claim for a surplus.

How a House Becomes Eligible for the Auction in the First Place

A property does not go to auction the moment a tax payment is missed.

Under California Revenue and Taxation Code §3691, a property generally has to be tax-defaulted for five years or more before the tax collector has the power to sell it at public auction — three years or more for nonresidential commercial property, or three years if a city, county or nonprofit has specifically requested the sale under a nuisance-abatement process.

For an ordinary single-family home or condo in San Diego County, the five-year clock is the one that applies.

That five years runs from when the property first became tax-defaulted, not from the date of the most recent unpaid bill, and the county sends multiple notices before the auction — including the formal Notice of Impending Power to Sell — but once the statutory period has run, the county has the legal authority to sell the property to satisfy the unpaid taxes, regardless of how much equity the owner has in it.

This is the single biggest misunderstanding homeowners have about property tax delinquency: a missed payment or two does not put a house at the auction. It takes years of continued nonpayment, with notice at every stage, before San Diego County’s Treasurer-Tax Collector can actually auction the property.

That window is exactly why most homeowners facing real tax trouble still have time to sell the house themselves, keep whatever equity exists, and avoid the auction process altogether.

The Right to Redeem Lasts Right Up Until the Sale

Before San Diego County ever gets to actually auction a tax-defaulted property, the owner of record keeps the right to redeem it — pay off the defaulted taxes in full, plus penalties and costs — any time before the sale is completed.

The redemption penalty under Revenue and Taxation Code §4103 runs at 1½ percent a month on the defaulted amount starting the July after the default is declared, which compounds into a meaningful number over several years but is still almost always smaller than losing the house outright.

The closer a redemption gets to the scheduled sale date, the more it can cost: §4112 adds a separate $150 fee on top of the redemption amount if the owner redeems within 90 days of the proposed tax sale date, which exists specifically because the county has already started incurring the costs of preparing that particular property for auction by that point.

Redeeming is not an option once the county’s deed to the purchaser has actually been recorded — at that point the property is sold, and the former owner’s only remaining avenue is the excess-proceeds claim described above, not getting the house back.

What Happens to Other Liens When the Tax Deed Records

A recorded tax deed generally wipes out most liens that were recorded against the property before the sale — mortgages, judgment liens, HOA liens — which is exactly why those lienholders get first priority on any excess proceeds instead: the sale extinguishes their security interest in the property itself, so the excess-proceeds claim is often the only recovery left to them.

Not every lien disappears the same way.

Certain government liens, including some federal tax liens, can carry separate redemption or notice rights that survive a county tax sale, and anyone relying on a tax-sale purchase to deliver clean title should confirm which liens were actually recorded against a specific parcel before assuming the sale wiped all of them out.

Heirs Can Often Claim Without Opening a Full Probate

If the person who held title before the tax deed recorded has since died, their heirs do not necessarily need to open a full probate case just to collect an excess-proceeds claim.

California’s small-estate affidavit procedures under the Probate Code let heirs claim personal property — which an excess-proceeds claim legally is, since the real property itself is already gone by the time the claim exists — by affidavit rather than through full administration, as long as the claim amount fits within the small-estate thresholds.

Given how often a tax-defaulted property sits in an estate precisely because nobody opened probate in time to sell it the normal way, this affidavit route can matter more here than in an ordinary house sale, and it is worth raising directly with San Diego County’s Tax Sales Section rather than assuming a full probate case is required before any claim can be filed.

How the County Runs the Auction

San Diego County’s Treasurer-Tax Collector runs its own public auction of tax-defaulted properties, with bidder registration, terms and conditions, and a schedule of upcoming sales all handled through the Tax Collector’s own office.

Prospective bidders have to register in advance and agree to the county’s posted terms before they can bid, and the minimum opening bid on a given parcel is set to cover the delinquent taxes, penalties, interest and costs the county is owed — not the property’s fair market value.

That gap between the minimum bid and what the property is actually worth is exactly where excess proceeds come from when a competitive auction pushes the winning bid above what the county was owed.

What “Excess Proceeds” Actually Means

When a tax-defaulted property sells at auction for more than the county needed to satisfy the delinquent taxes, assessments, penalties, interest and the costs of the sale itself, the leftover money is the excess proceeds.

San Diego County specifically defines excess proceeds as any amount remaining above $150 once those costs are satisfied — the $150 figure is the county’s own cutoff, below which there is nothing left worth the administrative process of distributing.

If a house with meaningful equity ends up at auction and sells competitively, that excess can be tens or even hundreds of thousands of dollars, and it does not automatically go to the former owner.

It has to be claimed, by the right person, within the deadline, using the county’s own process.

The One-Year Deadline, With No Exceptions

San Diego County’s own claim-filing instructions are direct about this: “all claims must be filed not later than one year from the date the tax deed is recorded otherwise the claim cannot be considered,” and the instructions add that “there are no exceptions to the one-year period to file a claim.” That clock starts when the tax deed to the purchaser is recorded, which is after the auction closes and the sale is finalized — not on the date of the auction itself, and not on the date the former owner first learns the property sold.

Missing that one-year window, for any reason, forfeits the claim permanently. There is no statutory grace period and no county discretion to extend it.

Who Actually Gets Paid First

California Revenue and Taxation Code §4675 sets the priority order for excess proceeds, and the former homeowner is not first in line.

Lienholders of record — mortgage holders, judgment creditors, HOA lien holders, and anyone else with a recorded lien against the property before the tax deed was recorded — are paid first, in the order of their recorded priority.

Only after every lienholder of record has been satisfied does any remaining balance go to whoever held title to the property immediately before the tax deed was recorded.

If the former owner has died, their heirs can claim by affidavit under the Probate Code’s small-estate provisions rather than opening a full probate case just for this claim, depending on the amount involved.

In practice, this means a house that went to auction with a mortgage balance still outstanding will often see most or all of the excess proceeds absorbed by the lender before the former owner sees anything — which is one more reason it is almost always better to sell before the auction than to let a mortgaged, tax-delinquent property run out the five-year clock.

Filing the Claim Itself

San Diego County requires a separate claim form for each owner of record, including spouses who both held title, and an assignment of any claim to someone else has to be documented with its own instrument rather than handled informally.

Claims and supporting documentation go to the county’s Tax Sales Section, and the office that processes them is the San Diego County Treasurer-Tax Collector at 1600 Pacific Highway, Room 162, San Diego, CA 92101, reachable at (619) 531-5708 for questions about a specific parcel or claim status.

The county can also assess a processing fee against the claimant’s share of the proceeds, and a separate notice-cost fee under Revenue and Taxation Code §4674 and the county’s own Administrative Code §364.4, both of which come out of the award rather than being billed separately up front.

After You File: The 90-Day Payment and the 90-Day Challenge Window

Once a claim is approved, San Diego County issues an Award Letter to the claimant, and the actual county warrant — the payment itself — is issued 90 days after the date of that Award Letter, not immediately.

That delay exists because the county has to give other potential claimants, including lienholders who might not have been obvious from the record, a chance to come forward.

Separately, anyone who wants to challenge the county’s award decision — a competing claimant who thinks they, not you, should have received the money, for example — has 90 days after the decision to file that challenge.

Both of those 90-day windows run independently of the one-year deadline to file the original claim, and both can add real time to how long it takes to actually see the money even after a claim is correctly filed and approved.

The Notices the County Sends Before a Property Ever Reaches the Auction

San Diego County does not quietly wait out the five-year default period and then surprise an owner with an auction notice.

Once a property is declared tax-defaulted, the county is required to send annual notices showing the growing defaulted amount, and as the property approaches its eligibility for sale, the Tax Collector issues a formal Notice of Impending Power to Sell identifying the specific parcel and warning that it is approaching the point where the county can legally auction it.

That notice typically goes to the last known address on file for the owner, which is one reason an owner who has moved, or an heir who inherited a house and never updated the mailing address with the Assessor, can end up missing the warnings entirely until a neighbor mentions the auction sign or the house shows up in a published legal notice.

Before the actual sale, the county also publishes a legal notice identifying every parcel scheduled for that auction, which is a matter of public record and is how most third-party investors and title researchers first learn a specific property is coming up for sale.

A Practical Example of Why Priority Matters

Say a house with a $280,000 mortgage balance and $40,000 in defaulted property taxes, penalties and costs goes to auction and a competing bidder wins it for $350,000. The county first takes what it is owed — the $40,000 in taxes, penalties and sale costs — leaving $310,000 in proceeds.

Under the priority order in Revenue and Taxation Code §4675, the mortgage lender’s recorded lien gets paid next, in full, before the former owner sees a dollar: that leaves $30,000 as the actual excess-proceeds claim available to the former owner, not the full $310,000 difference between what the house sold for and what the county was owed.

Any junior lienholders — a second mortgage, a judgment creditor, an HOA with a recorded lien — would be paid out of that remaining amount in their own recorded order before the former owner collects anything at all.

This is the calculation that matters most to a homeowner deciding whether letting a property run all the way to auction actually preserves more equity than selling it directly once default becomes unavoidable, and in most cases with an outstanding mortgage, it does not.

Why This Rarely Needs to Happen

Every aspect of the tax-default foreclosure process – the five-year default period, the auction, the excess-proceeds claim, lienholder priority, the one-year time limit – all were established because a homeowner’s equity was trapped because of an unpaid tax bill. Nothing is pre-ordained.

A homeowner significantly behind on their property taxes usually has options well in advance of the five-year mark that will allow them to keep more equity than from an auction and a lengthy excess-proceeds claim.

Some of those options are a payment plan with the Tax Collector, a sale on the open market, or a sale to a cash buyer, and each of them keeps the decision in the owner’s hands instead of leaving the outcome to a public auction and whichever bidder shows up for it.

Confirm exactly how many years the property has been tax-defaulted, not just whether a bill is currently unpaid
Check for any recorded liens against the property — they get paid before you do if the house ever does reach auction
Ask the county’s Tax Sales Section directly about a specific parcel’s status rather than guessing from the mailed notices alone
If a sale already happened at auction, calendar the one-year claim deadline the day you learn about it
If the property is still yours and not yet sold, get a redemption payoff quote from the Tax Collector before assuming the house is a lost cause
