Understanding Property Taxes When Buying in California

Buying a home in California is an exciting milestone—but it also comes with unique costs that many first-time buyers aren’t fully prepared for. One of the most important (and sometimes confusing) aspects of homeownership here is understanding California property taxes.

At Seabrooke Group, we believe that an informed buyer is an empowered buyer. This guide will walk you through everything you need to know about property taxes when buying a home in California, from how they’re calculated to how you can plan for them wisely.

What Are Property Taxes and Why Do They Matter?

Property taxes are annual taxes paid by homeowners to fund essential public services like schools, fire departments, infrastructure, and parks. These taxes are collected by your county tax assessor and are a recurring cost of homeownership.

If you're budgeting to buy your first home, understanding these real estate taxes in California is critical for avoiding unpleasant surprises after you close.

How Property Taxes Are Calculated in California

The base property tax rate in California is 1% of a property's assessed value, thanks to Proposition 13, a law that has shaped the state’s real estate tax system since 1978.

Here’s how it works:

• Your property’s assessed value is based on the purchase price at the time you buy.

• This assessed value can only increase by a maximum of 2% per year, unless the property is sold or significantly improved.

• On top of the 1% base rate, local governments can add voter-approved special assessments and bonds, increasing your total tax bill slightly.

• Example: If you buy a home for $700,000, your base property tax would be $7,000/year. With local fees, your actual bill could be closer to $8,000–$9,000.

A knowledgeable Realtor in California—like the team at Seabrooke Group—can help you estimate your taxes before making an offer.

Understanding Mello-Roos and Special Assessments

California has areas known as Mello-Roos districts, which impose additional taxes to fund new schools, roads, or community improvements. These taxes can last for 20–40 years.

Before buying a home, check:

• If it’s in a Mello-Roos district

• The amount and duration of the additional tax

• How it affects your monthly housing budget

• 
  

You’ll also want to review special assessments like lighting, landscaping, or flood control district fees. Your Realtor in California can help you read the preliminary title report to see what applies.

What Is a Supplemental Property Tax Bill?

One common surprise for first-time buyers is the supplemental property tax bill. When you buy a home, your county reassesses the value and issues a one-time supplemental tax bill—separate from your regular taxes.

Key things to know:

• It’s not always included in your mortgage payment

• It can arrive a few months after closing

• It’s based on the difference between the old and new assessed values

Seabrooke Group always prepares our buyers for this so they can budget for property taxes in the first year.

When Are Property Taxes Due in California?

Property taxes in California are due in two installments:

• First Installment: Due November 1, delinquent after December 10

• Second Installment: Due February 1, delinquent after April 10

  
  

Most buyers choose to pay taxes through their escrow account, which is managed by their mortgage lender and included in their monthly payment.

Property Tax Exemptions for California Homeowners

You may be eligible for tax savings through exemptions and relief programs:

• Homeowner’s Exemption: Reduces your taxable value by $7,000, saving around $70 annually.

• Disabled Veterans Exemption: Offers significant tax breaks to qualifying veterans.

• Property Tax Postponement Program: Available for seniors, blind, or disabled homeowners meeting certain income and equity requirements.

  
  

If you’re unsure whether you qualify, our team at Seabrooke Group can guide you through the process or connect you with your county tax assessor.

How to Budget for Property Taxes

To avoid being caught off guard:

• Ask your Realtor in California for a tax estimate based on current assessments

• Use online calculators from your county assessor’s website

• Include property taxes in your monthly housing budget, along with insurance and HOA fees if applicable

• Set aside extra for supplemental tax bills and possible Mello-Roos assessments

Common Mistakes First-Time Buyers Make

Let’s avoid these:

• Ignoring Mello-Roos or special assessments

• Not budgeting for supplemental taxes

• Forgetting to apply for exemptions

• Assuming your tax bill will match the seller’s (your reassessment will reset it!)

  
  

Working with an experienced Realtor in California, like those at Seabrooke Group, helps you sidestep these pitfalls and make confident decisions.
