A Los Angeles County home does not go to a tax auction the moment a property tax payment is missed — it takes five years of unpaid taxes on a residential parcel (three years for most commercial property) before the Treasurer and Tax Collector gains the legal “power to sell” at public auction, and even then, a homeowner can usually stop the sale right up to the day before it happens.

Understanding exactly where that five-year clock starts, what notices precede the auction, and how to claim money left over if a sale does happen can mean the difference between losing a house for pennies on the dollar and walking away with real equity intact.

We’ve covered the broader statewide version of this process in foreclosure surplus funds in California and whether you can sell a house with back taxes owed, but Los Angeles County’s own Treasurer and Tax Collector runs its own version of the tax-default process with its own office, forms, and contact numbers.

When the Five-Year Clock Actually Starts

A property becomes tax-defaulted the moment an annual installment goes unpaid past its final due date, which is typically June 30.

From that default date, Los Angeles County’s Treasurer and Tax Collector (TTC) must wait five years for residential property, or three years for most non-residential commercial property, before it gains the power to sell the parcel at auction.

The five-year period is not five years from today’s unpaid bill — it runs from whichever tax year first went unpaid, so a homeowner who has been behind for several years is often closer to the auction threshold than they realize, even if they have made partial or recent payments toward the growing balance.

The Notices That Come Before an Auction

Once the five-year threshold is reached, the TTC does not auction a property without warning. A homeowner first receives a Notice of Impending Power to Sell, followed later by an Official Notice of Auction once a specific sale date is set.

Both notices state the amount required to redeem the property and stop the sale, and both are mailed to the address of record — which is exactly why keeping a current mailing address on file with the Assessor’s office matters for anyone who has moved, is managing an inherited property from out of state, or has let mail pile up during a difficult financial period.

A Statement of Prior Year Taxes, available on request, breaks down the annual defaulted amounts, accumulated penalties, and costs that make up the total owed.

Redemption: Stopping the Sale Up Until the Last Business Day

A homeowner can redeem a tax-defaulted property — meaning pay the full delinquent taxes, accrued interest, and penalties through the TTC — at any point before the auction, right up to 5:00 p.m. Pacific Time on the last business day before the scheduled sale.

Once that deadline passes, redemption is no longer available and the auction proceeds as scheduled.

The exact amount required to redeem is stated on the Official Notice of Auction itself, and a homeowner who has lost track of the running total should contact the TTC directly rather than estimate from an old tax bill, since penalties and costs continue to accrue the entire time the property sits in default.

Installment Plans Can Also Stop the Clock

Beyond paying the full redemption amount outright, the TTC’s own notices reference the option of initiating an installment plan to avoid the sale, which allows a homeowner to spread the defaulted balance across payments rather than producing the entire sum at once.

The specific eligibility rules and payment structure are not detailed on the notices themselves, so a homeowner who cannot pay the full redemption amount by the deadline, but could manage a payment plan, should contact the TTC directly — at (213) 974-2111, or toll-free at (888) 807-2111 — well before the auction date rather than assuming a plan is automatically available or waiting until the final notice arrives to ask.

Selling the Property Instead of Redeeming It

A homeowner facing an approaching auction date is not limited to redeeming the taxes or losing the property — selling before the sale date is also a legitimate way to resolve a tax-defaulted parcel.

The back taxes can be paid directly out of the sale proceeds at closing, or, in some negotiated transactions, the seller can give the buyer a closing credit equal to the amount owed and let the buyer handle payoff.

Either way, a sale has to actually close — meaning escrow has to fund and the deed has to record — before the auction date, since a pending sale in progress does not by itself pause the county’s power-to-sell timeline the way a bankruptcy filing can pause a foreclosure.

A seller working against an auction deadline needs a buyer, and a closing process, capable of moving faster than a standard 30- to 45-day escrow.

What Happens at the Auction Itself

Once the redemption deadline passes without payment or an installment arrangement, the TTC proceeds with the scheduled public auction, and the property is sold to the highest bidder for at least the minimum bid, which covers the defaulted taxes, penalties, and costs accumulated against the parcel.

Unlike a conventional real estate sale, an auction buyer typically takes the property subject to limited rights of inspection and without most of the representations a conventional buyer would expect, which is part of why auction sale prices on occupied or unseen properties can run well below fair market value — and why the gap between the minimum bid and the final sale price is often where real, recoverable money is left for the former owner.

Excess Proceeds: The Money Left on the Table

When an auction sale price exceeds the minimum bid — the actual back taxes, penalties, and costs owed — the difference is called excess proceeds, and it does not default to the county.

California law gives the former owner and any lienholders of record the right to claim it, but only if they actually file a claim within the statutory window, which is one year after the tax deed is recorded to the auction purchaser.

The county is required to make a reasonable effort to identify and mail notice to every party of interest within 90 days after the sale is complete (meaning the date the TTC received full payment from the auction buyer), and where no address can be located, the county must publish notice in a newspaper of general circulation once a week for three consecutive weeks, starting within that same 90-day window.

Who Gets Paid First

Excess proceeds are not split evenly among everyone with a claim — they follow a strict statutory priority. Lienholders of record whose liens predate the recorded tax deed are paid first, in the order their liens had priority against the property.

Only after lienholders are satisfied do titleholders of record — the former owner, or heirs with appropriate probate documentation if the owner is deceased — receive what remains. Where a property had more than one owner, each is entitled only to their proportional ownership share of what is left.

A former owner who assumes they are simply owed the entire excess amount, without checking whether a recorded lien (a judgment, an HOA assessment, or an old second mortgage) sits ahead of them in priority, can be surprised by how much smaller their actual recovery is.

Pulling a current preliminary title report or a lien search before filing a claim is worth doing early, since it tells a former owner roughly what to expect rather than leaving them to find out only after the county has processed every other claimant ahead of them in line.

Filing the Claim

A claim is timely if it is postmarked by the one-year deadline; if a mailed claim carries no postmark, the date the county actually receives it controls instead.

Heirs of a deceased former owner can claim with the appropriate probate documentation establishing their right to the property’s proceeds, and anyone filing on behalf of another claimant, or as an assignee of the original claimant’s right, should expect to provide additional supporting documentation beyond a basic claim form.

The county’s Board of Supervisors, or an officer it designates, ultimately decides eligibility and the amount owed to each claimant, and a claimant who disagrees with that decision generally has a limited window — around 90 days — to seek further review before the determination becomes final.

A Tax Auction Is Not a Mortgage Foreclosure

Homeowners frequently confuse a tax-defaulted property auction with a mortgage foreclosure trustee’s sale, but the two run on entirely separate timelines, through entirely separate offices, and can even happen to the same property independently of each other.

A mortgage foreclosure follows a lender’s notice of default and typically moves in a matter of months; a county tax sale follows years of unpaid property taxes and moves on the multi-year schedule described above.

It is entirely possible for a property to be current on its mortgage while sitting in tax default, or paid off entirely with no mortgage at all while still heading toward a tax auction — property taxes are owed regardless of whether there is a loan on the house.

A homeowner managing both a missed mortgage payment and overdue property taxes is dealing with two separate deadlines, two separate sets of notices, and two separate processes that do not pause for each other.

What an Auction Buyer Actually Receives

An auction purchaser receives a tax deed, not a grant deed backed by a conventional title insurance policy, and most title insurers will not issue standard coverage on a freshly auctioned parcel until a quiet title action has run its course — a process that itself can take the better part of a year.

This is part of why tax-auction sale prices often land well under a property’s fair market value even for a desirable house: institutional and experienced investor buyers price in the title risk, the possibility of needing to evict a prior occupant, and the delay before the property can be resold with clean, insurable title.

For a former owner, this same gap is exactly where the opportunity for excess proceeds tends to come from — a motivated auction bidder paying a meaningful premium over the minimum bid despite those added risks and delays.

A Working Example

Say a homeowner in the San Gabriel Valley inherited a house with a defaulted tax bill, fell further behind managing it from out of state, and missed both the Notice of Impending Power to Sell and the later Official Notice of Auction because the mailing address on file was outdated.

The TTC auctions the property at a minimum bid of roughly $42,000 covering five years of defaulted taxes, penalties, and costs. A bidder, seeing a desirable property in a strong submarket, pays $310,000 at auction.

The roughly $268,000 difference becomes excess proceeds, and the former owner — now notified, or tracked down through the public notice published after the county could not locate a current address — has one year from the recorded tax deed to file a claim and recover that difference, provided no lienholder with higher priority is in line ahead of them.

Partial Payments Do Not Reset the Clock

A homeowner who has been making partial or sporadic payments toward a growing tax bill sometimes assumes those payments restart the five-year default period, or at least pause it. They do not.

The five-year countdown runs from the date the oldest unpaid installment first went into default, and a partial payment reduces the total balance owed without changing that starting date.

The only way to stop the clock entirely is to bring the account fully current through redemption, or to enter one of the installment plans the TTC offers, which formally suspends the power-to-sell timeline rather than merely slowing it.

A homeowner who has been chipping away at a balance for several years without realizing the underlying default date never moved should confirm the actual auction eligibility date with the TTC directly rather than assume recent payments have bought more time than they have.

A Pre-Auction Checklist

Confirm the current mailing address on file with the Assessor and the TTC so auction notices actually reach you.
Request a Statement of Prior Year Taxes to see the real total owed rather than estimating from an old bill.
Call the TTC directly to ask about an installment plan if the full redemption amount is out of reach by the deadline.
If selling instead of redeeming, confirm with a title company or cash buyer that a closing can realistically fund before the scheduled auction date.
If an auction has already occurred, check whether the parcel sold for more than the minimum bid, and file an excess proceeds claim within one year of the recorded tax deed if so.

When Selling to a Cash Buyer Is the Wrong Move

If there is still meaningful time before the auction date and real equity in the property beyond the defaulted taxes, a fully marketed listing or a short escrow with a conventional buyer can still produce a materially better outcome than a fast as-is cash sale, since the gap between a discounted cash offer and a fully marketed price is often larger than the cost of a few extra weeks of carrying the property.

A direct cash sale makes the most sense when the auction date is close enough that a conventional closing genuinely cannot beat it, when the property’s condition or an existing tenancy would slow a traditional sale past that deadline, or when a homeowner has already missed the point where redemption or an installment plan is realistic and needs certainty more than maximum price.
