Property taxes are one of those bills that can sneak up on you. Maybe you lost your job. Maybe medical bills took priority. Maybe you inherited a property and didn’t realize the taxes were years behind. Whatever the reason, unpaid property taxes in California trigger a process that can eventually cost you your home.
The good news: California gives you significantly more time than most states before things get truly dire. The bad news: most homeowners don’t use that time wisely. Here’s exactly what happens when you fall behind, how much time you actually have, and what you can do about it.
How California Property Taxes Work
California property taxes are due in two installments:
- First installment: Due November 1, delinquent after December 10
- Second installment: Due February 1, delinquent after April 10
If you miss either deadline, a 10% penalty is added immediately. If you miss both installments for the entire fiscal year, additional fees and costs start accumulating.
Your property tax rate in California is based on Proposition 13, which caps the assessed value increase at 2% per year. But that doesn’t help if you can’t pay the bill at all.
The Tax Default Process
Year 1: Tax Default
If you don’t pay your property taxes by the end of the fiscal year (June 30), the county tax collector declares your property tax defaulted on July 1. Under Revenue and Taxation Code Section 3436, this happens automatically — no hearing, no warning letter triggering it.
At this point:
- A $15 redemption fee is added to your account
- 1.5% per month interest (18% annual rate) starts accruing on the unpaid taxes
- The default is recorded against your property’s title
You’ll receive a notice from the county tax collector informing you of the default. Don’t ignore it.
Years 2–4: Accumulating Debt
Each year you don’t pay, the situation compounds:
- New property taxes are added to the existing delinquent amount
- Interest continues accruing at 1.5% per month
- Additional penalties and fees accumulate
- Your total debt grows significantly
Here’s a simplified example of how fast the debt grows:
| Year | Original Tax Due | Accumulated Penalties & Interest | Approximate Total Owed |
|---|---|---|---|
| Year 1 | $5,000 | $900+ | ~$5,900 |
| Year 2 | $5,000 (new year) | $2,500+ | ~$12,400 |
| Year 3 | $5,000 (new year) | $4,800+ | ~$19,800 |
| Year 4 | $5,000 (new year) | $7,900+ | ~$27,900 |
| Year 5 | $5,000 (new year) | $11,800+ | ~$36,800 |
These numbers vary based on your actual tax amount and the timing of penalties, but the trend is clear: waiting makes it worse.
Year 5: Power to Sell
Under Revenue and Taxation Code Section 3691, after a property has been tax defaulted for five years, the county tax collector has the power to sell it at a tax auction. For properties with a homeowner’s exemption, the period is extended to five years. For non-homestead properties, it can be as few as three years.
Before selling your property, the county must:
- Mail you a Notice of Intent to Sell (at least 90 days before the auction)
- Publish notice in a local newspaper
- Post notice on the property (if possible)
- Make reasonable efforts to contact the owner
This is your last major warning. If you receive a Notice of Intent to Sell, treat it as an emergency.
Tax Defaulted Property Auctions
If you don’t pay the delinquent taxes before the auction date, the county sells your property to the highest bidder. Here’s how it works:
- Minimum bid: The total amount of delinquent taxes, penalties, interest, and costs
- Bidding: Public auction (increasingly done online in many California counties)
- Payment: Winning bidder pays the full amount at the auction
- Title: The buyer receives a tax deed, which transfers ownership free and clear of most liens and encumbrances
What you lose: Everything. The buyer gets the property. Any equity above the tax debt? In California, excess proceeds from the sale go to the former owner — but only if you file a claim. Many people don’t know this and walk away from thousands of dollars.
What you keep: Nothing, unless you file for excess proceeds within one year after the sale (Revenue and Taxation Code Section 4675).
The Redemption Period: Your Window to Save Your Home
California’s redemption period is one of the most generous in the country. You can redeem (pay off) your delinquent taxes at any time before the property is actually sold at auction.
To redeem, you must pay:
- All delinquent tax amounts
- All penalties (10% of each installment)
- Redemption fee ($15)
- All accrued interest (1.5% per month)
- Any costs associated with the impending sale
Many county tax collectors offer installment plans for redemption under Revenue and Taxation Code Section 4216. You can typically spread the delinquent amount over five years with 1.5% monthly interest on the unpaid balance. This requires filing an application with the tax collector.
Supplemental Tax Bills: The Hidden Surprise
Many homeowners don’t realize that supplemental property taxes can create delinquencies they didn’t expect.
When you buy a home or complete new construction, the county assessor recalculates your property taxes based on the new assessed value. The difference between the old tax and the new tax — prorated for the remaining fiscal year — is your supplemental tax bill.
These supplemental bills:
- Are mailed separately from your regular tax bill
- Are not included in your mortgage escrow account
- Have their own due dates and penalty deadlines
- Can go delinquent without you realizing it
If you bought a home in the last few years and haven’t checked for supplemental bills, do it now. Unpaid supplemental taxes follow the same default process as regular property taxes.
How Property Tax Debt Affects Your Home
Beyond the risk of losing your home at auction, unpaid property taxes create other problems:
You Can’t Sell Easily
Property tax liens attach to the property, not to you personally. Any buyer (or their title company) will discover the delinquent taxes during the title search. The taxes must be paid at closing before the sale can proceed.
You Can’t Refinance
No lender will refinance a mortgage on a property with delinquent taxes. Tax liens take priority over mortgage liens, which means the lender’s security is at risk.
Your Mortgage Company May Pay Them for You
If your mortgage has an escrow account, your lender is supposed to pay your property taxes. But if you don’t have escrow — or if supplemental bills slip through — and the lender discovers delinquent taxes, they may pay them and add the amount to your mortgage balance. This is called a lender advance, and it increases your monthly payment.
It Complicates Everything
Whether you’re trying to sell, refinance, take out a home equity line, or even pass the property to heirs — delinquent taxes create roadblocks at every turn.
Selling Your Home to Clear Tax Debt
If you can’t afford to pay the delinquent taxes and want to avoid losing your home at auction, selling the property is often the smartest move. Here’s why:
Taxes Get Paid at Closing
When you sell, the title company handles the payoff. Delinquent taxes, penalties, and interest are paid from the sale proceeds before you receive your share. You don’t need to come up with the money upfront.
You Keep Your Equity
A tax auction sells your home for the minimum bid — which is just the delinquent tax amount. If your home is worth $400,000 and you owe $25,000 in back taxes, selling it gives you access to the remaining equity. At a tax auction, you might lose most of that equity (excess proceeds require you to file a claim, and many people don’t).
You Control the Process
In a sale, you choose the buyer, the timeline, and the terms. At an auction, you have no control over anything.
How SHH Buys Homes Handles Tax-Delinquent Properties
We regularly buy properties with delinquent property taxes across Southern California. Here’s how it works:
- We assess the total debt. We work with the county tax collector and title company to determine exactly what’s owed — regular taxes, supplementals, penalties, and interest.
- We pay it all at closing. The delinquent taxes come out of the sale proceeds. You don’t need to bring any cash to the table.
- We close fast. If a tax auction is approaching, time matters. We can close in as little as 7 to 14 days.
- We buy as-is. Tax-delinquent properties often have deferred maintenance. We don’t require repairs.

Frequently Asked Questions
Can I make partial payments on delinquent property taxes? Yes — if you set up an installment plan through the county tax collector. Without an installment plan, partial payments are generally not accepted for delinquent taxes (though policies vary by county).
What if I inherited a property with unpaid taxes? You’re responsible for the delinquent taxes if you want to keep the property. If you can’t afford them, selling is usually the best option. The taxes get cleared at closing.
Do property tax liens expire in California? No. The lien remains on the property indefinitely until the taxes are paid. And after five years of default, the county can sell your property at auction.
Can I negotiate my property tax amount with the county? You can appeal your assessed value if you believe it’s too high (file with the Assessment Appeals Board). But you can’t negotiate away penalties and interest on delinquent taxes.
What if the tax auction has already been scheduled? Contact us immediately. If there’s enough time before the auction date, a cash sale can still clear the taxes and save your equity. But every day matters — don’t wait.
