Placer County Property Tax: Rates, Deadlines, and Appeals

Placer County property tax bills start with California’s 1% base rate on your property’s assessed value, plus voter-approved bond rates and any local or special district assessments that apply to your parcel. Bills come in two installments: the first is due November 1 and delinquent after December 10, and the second is due February 1 and delinquent after April 10. Miss either delinquency date and a 10% penalty is added automatically, with a $10 cost tacked on to a late second installment.

How Your Bill Is Calculated

Every bill begins with the assessed value. Under Proposition 13, that value is typically set at your purchase price and can rise by no more than 2% a year, regardless of what the market does, unless the property changes hands or you build something new.¹ The Placer County Assessor sets the value, and the Auditor-Controller applies the tax rates to produce the bill.²

The 1% rate is only the floor. Your bill also includes voter-approved bond rates for things like school construction and infrastructure.² Many Placer County neighborhoods also carry Mello-Roos charges or special assessment district fees that pay for localized improvements like roads, parks, fire protection, or sewer systems.³ Mello-Roos charges usually repay bonds issued to finance those improvements and have a set maturity date.⁴ Each of these shows as a separate line item on your bill. Together they determine what you owe for the year.

Payment Deadlines

Secured Property Taxes

Secured property taxes, the ones tied to real estate, are billed in two installments each fiscal year. The first installment is due November 1 and becomes delinquent at 5:00 p.m. on December 10. The second installment is due February 1 and becomes delinquent at 5:00 p.m. on April 10. A missed first installment adds a 10% penalty. A missed second installment adds a 10% penalty plus a $10 cost.⁵

If you mail your payment, what counts is the USPS postmark. A payment postmarked on or before December 10 or April 10 is timely even if it arrives days later. Postage meter stamps don’t qualify as official USPS postmarks, and neither do home banking or online bill-pay confirmations. If one of those payments shows up after the deadline, the penalty stands.⁵

Unsecured Property Taxes

Unsecured property taxes cover things that aren’t tied to real estate, such as business equipment, boats, and aircraft. These follow a different schedule. Bills go out in mid-July, with a single payment due by August 31. A 10% penalty kicks in on September 1 if the bill is unpaid. By November 1, the Tax Collector records liens and begins accruing a 1.5% monthly penalty, with collection actions that can include wage garnishment or seizure of assets.⁵

How to Pay Your Bill

You’ll need your 12-digit Assessment Number to make a payment. The number appears on your tax bill and is how the Tax Collector matches your payment to the right parcel. If you’ve misplaced the bill, you can look up the number on Placer County’s online property tax portal using your property address.⁶

Placer County accepts payments several ways:

By mail: send your check with the payment stub to Placer County Tax Collector, 2976 Richardson Drive, Auburn, CA 95603. Use the return envelope included with your bill and make sure it carries a USPS postmark on or before the delinquency date.⁶
Online: the county’s payment portal accepts e-checks and credit or debit cards. Credit and debit card payments carry a 2.45% convenience fee (minimum $2.75) charged by the third-party vendor.⁶
Drop box: a secure drop box sits in front of the Tax Collector’s office at 2976 Richardson Drive in Auburn for check payments without waiting in line.⁶

Check the online portal a few business days after any payment to confirm it was applied. The portal also shows prior-year balances, so you can verify you don’t have outstanding amounts quietly accruing interest.

Supplemental Bills After a Purchase or Renovation

If you recently bought a home or finished significant construction, expect a supplemental tax bill on top of your regular property taxes. California law requires the Assessor to reassess a property whenever it changes ownership or undergoes new construction, rather than waiting for the next regular assessment roll.⁷

The supplemental bill covers the difference between the old assessed value and the new one, prorated for the months remaining in the fiscal year. Close on a home in October where the new assessed value is $200,000 higher than the previous owner’s, and you’d owe 1% of $200,000 prorated across roughly nine months through June 30. You might receive two supplemental bills if the purchase date falls before January 1, because it affects both the current and upcoming fiscal years.

These bills are mailed to you directly, even if your regular property tax payments go through a mortgage escrow account. That catches many new buyers off guard. An unpaid supplemental bill becomes delinquent and accrues penalties the same as a regular bill.

Getting a Late Penalty Canceled

Placer County can cancel late penalties, but only under narrow circumstances defined by state law. The Tax Collector has authority to waive penalties when the late payment resulted from reasonable cause and circumstances beyond your control, and you exercised ordinary care in trying to pay on time. You must pay the full amount owed no later than June 30 of the fourth fiscal year after the tax became delinquent.⁸

Penalties can also be waived if you made an inadvertent error in your payment amount, as long as you pay the correct amount within 10 days of the Tax Collector mailing a shortage notice.⁸ Requests that boil down to “I mailed it on time but it arrived late” or “I have a good payment history” are routinely denied. A documented medical emergency or natural disaster carries more weight than a claim about postal delays.

Exemptions That Reduce Your Bill

Homeowners’ Exemption

If you own and occupy a home as your primary residence in Placer County, you can claim the homeowners’ exemption for a $7,000 reduction in assessed value. That translates to roughly $70 in annual savings at the 1% base rate. The exemption does not apply to rental properties, vacation homes, vacant properties, or homes under construction on the lien date.⁹ It’s a small amount, but there’s no reason to leave it on the table. File the claim with the Placer County Assessor. Once granted, it stays in effect until you move or change how you use the property.

Disabled Veterans’ Exemption

Disabled veterans can qualify for a much larger exemption. The basic exemption started at $100,000 and is adjusted annually for inflation. A low-income version started at $150,000 with its own annual adjustments and a household income cap that is also adjusted each year.¹⁰ For veterans with a 100% disability rating and low income, the exemption can effectively eliminate the tax bill. Contact the Placer County Assessor for the current year’s exemption amounts and income thresholds.

Proposition 8 Decline-in-Value Reductions

Proposition 13’s 2% annual cap on assessed value is a long-term protection, but it doesn’t help when market values fall. Proposition 8 does. If your home’s current market value drops below its Proposition 13 factored value (the purchase price plus accumulated 2% annual increases), you can request a temporary reduction in assessed value. The Assessor lowers the assessed value to match current market value, reducing your bill until the market recovers, at which point the assessed value reverts to the Proposition 13 factored value.¹

Property Tax Postponement for Seniors and Disabled Homeowners

California’s Property Tax Postponement Program lets qualifying homeowners defer their property tax payments. The state places a lien on the home, and the deferred taxes plus interest come due when the homeowner sells, moves out, or passes away. To qualify, you must be a senior, blind, or have a disability, with a household income of $55,181 or less and at least 40% equity in the home. For the 2025–26 program year, the filing period closes on February 10, 2026.¹¹

Appealing Your Assessed Value

If you believe the Assessor’s value on your property is too high, you can file an appeal with Placer County’s Assessment Appeals Board. Placer County’s regular filing window runs from July 2 through September 15 each year, one of the shorter windows in California, where many counties allow until November 30.¹² Miss September 15 and you’ll wait another year.

For supplemental assessments triggered by a purchase or new construction, you have a separate 60-day window from the date on the supplemental notice. If you never received a notice, you can still file during the regular filing period for the year the value first appears on the assessment roll, or within the following three years.¹²

Once you file, the Board has up to two years to schedule a hearing. You’ll receive written notice at least 45 days before your hearing date and must respond at least 30 days before.¹² The strongest appeals rest on recent comparable sales of genuinely similar properties in the same area: similar age, size, condition, and lot quality. A raw list of addresses and prices won’t move the needle. You need to explain why each sale supports a lower valuation for your specific property. Photographs of deferred maintenance, repair estimates, and a professional appraisal (typically $300 to $1,200 for a residential property) can strengthen your case. If the appeal focuses on assessment uniformity rather than market value, comparable assessment data for similar nearby properties may carry more weight than comparable sales.

What Happens If You Don’t Pay

Falling behind on property taxes starts a clock that eventually leads to losing the property. When secured taxes remain unpaid, the property enters tax-defaulted status. From there, a redemption period runs for five years for residential and agricultural property, or three years for commercial and vacant land. During that period you can pay the back taxes, penalties, and accumulated costs to bring the account current.

If the redemption period expires without payment, the Tax Collector gains the power to sell the property at public auction. Before any sale, the county must send multiple notices to the owner and anyone with a recorded interest, including a courtesy notice as the default period nears its end, a notice of impending power to sell, and a formal notice of the auction with the date, time, redemption amount, and information about excess proceeds. The property can still be redeemed up to the close of business on the last business day before the sale.

Even if you can’t pay the full amount right away, contact the Placer County Tax Collector to discuss your options before the property reaches tax-defaulted status. Penalties and interest during default add up fast, and this is one of the few areas in law where the government can take your home without a traditional foreclosure lawsuit.
