Prop 19 in Santa Barbara County: Keep Your Tax Base at 55+
Can I keep my low property taxes if I sell my Orcutt or Santa Maria home after 55?
Yes, if you qualify. Under California’s Prop 19, homeowners 55 and older can transfer the taxable value of their primary residence to a replacement primary residence anywhere in California, up to three times. You have two years between selling and buying, in either order. If the new home costs more, only the difference in market value is added to your existing tax base. You file the claim (form BOE-19-B) with the county assessor where the new home is located, within three years of buying it.

If you’ve owned your home in Orcutt or Santa Maria for 15 or 20 years, your property tax bill is probably based on a value far below what the home is worth today.
That’s Prop 13 at work. And it’s the reason so many long-time owners tell me some version of the same thing: “We’d love to downsize, but our property taxes would triple.”
For homeowners 55 and older, that’s often not true anymore. Prop 19 changed the rules in 2021, and it’s one of the most underused tools for local homeowners thinking about their next move.
Here’s how it works, what it could save you, and the mistakes to avoid.
How Prop 19 works for homeowners 55 and older
Prop 19’s base-year value transfer lets you take the taxable value of your current home with you to your next one. The key rules, per the California State Board of Equalization:
- Who qualifies: homeowners 55 or older, severely disabled homeowners, and victims of wildfire or other Governor-declared disasters
- What qualifies: both homes must be your primary residence — not a rental or vacation home
- Where: the replacement can be anywhere in California, not just Santa Barbara County
- How many times: up to three times if you qualify by age
- Timing: you must buy or build the replacement within two years of selling your original home — before or after the sale
- Filing: you file form BOE-19-B (age-based) with the assessor in the county where your new home is, within three years of buying it
Under the old rules (Props 60 and 90), you could do this only once, usually only within the same county, and only if the new home cost the same or less. Prop 19 removed most of those limits.
If your new home costs the same or less
Your existing taxable value transfers to your new home. There’s a small allowance built in, depending on timing — the replacement can be worth up to 100% of your old home’s sale price if you buy first, or up to 105% or 110% if you buy within the first or second year after selling.
If your new home costs more
You can still transfer your tax base. The difference between the new home’s value and your old home’s value is added on top.
The Board of Equalization’s own example: if your current taxable value is $300,000, your home sells for $600,000, and your new home costs $700,000, your new taxable value would be $400,000 — your $300,000 base plus the $100,000 difference.
What it could save you: two Orcutt examples
Let’s say you bought your Orcutt home in 1998. Your current taxable value is about $350,000, and the home sells today for $1,050,000.
Property tax rates in Santa Barbara County generally run a little over 1% of taxable value once local voter-approved charges are included. I’ll use 1.1% to keep it simple — your actual rate depends on your tax rate area and any special assessments.
Example 1: Downsizing to an $800,000 home in Orcutt
- Without Prop 19: taxed on $800,000 → about $8,800 a year
- With Prop 19: your $350,000 base transfers → about $3,850 a year
- Savings: roughly $4,950 a year, every year you own the home
Example 2: Moving to a $1,200,000 home closer to family elsewhere in California
- Without Prop 19: taxed on $1,200,000 → about $13,200 a year
- With Prop 19: $350,000 base + $150,000 difference = $500,000 → about $5,500 a year
- Savings: roughly $7,700 a year
Over ten years, that’s $50,000–$77,000 that stays in your pocket. For many retirees, that’s the difference between a move that works and one that doesn’t.
Pair that with the payment math in whether to give up your 3% mortgage to move, and downsizing often looks very different than people expect.
Mistakes that can cost you the benefit
Prop 19 is generous, but it’s strict about details. These are the ones I see trip people up.
- Missing the two-year window. The clock runs from the sale of your original home. If your replacement purchase falls outside it, the transfer is lost.
- Not filing the claim. The benefit isn’t automatic. You must file BOE-19-B with the assessor in the county where your new home is. Until it’s approved, you may be billed at the full purchase price and refunded later.
- Buying something that isn’t your primary residence. A second home or rental doesn’t qualify, and you need to own and live in the new home when you file.
- Forgetting supplemental tax bills. After you buy, the county may send a supplemental bill based on the full purchase price before your claim is processed. Budget for it, and keep an eye on your mail.
- Assuming the rules match what a friend did years ago. Props 60 and 90 had different limits. Anyone who moved before April 2021 followed the old rules.
If you’re timing a sale and a purchase together, the options in buying before you sell can help you stay inside the two-year window without carrying two homes for long.
A quick note for families inheriting a home
Prop 19 also changed how property taxes work when parents pass a home to their children. The short version: the low tax base only carries over if the child moves into the home as their primary residence within one year, and if the home’s market value exceeds the parents’ taxable value by more than about $1 million (an amount adjusted over time), the excess is added to the base.
If you’re inheriting a home in Santa Maria or Orcutt and don’t plan to live in it, the tax picture changes — and it’s worth talking with a CPA or estate attorney before deciding whether to keep, rent, or sell it.
Frequently Asked Questions
Who qualifies for Prop 19 base-year value transfer?
California homeowners who are 55 or older, severely disabled, or whose home was damaged or destroyed in a wildfire or Governor-declared disaster. Both the original home and the replacement must be the owner’s primary residence.
How many times can I use Prop 19?
Homeowners who qualify by age (55 or older) can transfer their base-year value up to three times. The old rules under Props 60 and 90 allowed only one transfer.
Can I transfer my Santa Barbara County property tax base to another county?
Yes. Under Prop 19, the replacement home can be anywhere in California. You file the claim with the assessor in the county where the new home is located.
What if my new home costs more than my old home sold for?
You can still use Prop 19. The difference between the new home’s market value and the old home’s sale price is added to your transferred taxable value, so your tax bill rises only by that difference.
How long do I have to buy a replacement home under Prop 19?
You must buy or build the replacement within two years of selling your original home, either before or after the sale. You then have three years from the purchase to file form BOE-19-B with the county assessor.
The bottom line
If you’re 55 or older and your property taxes are the reason you’ve stayed put, Prop 19 may change the math entirely. You can take your tax base with you, up to three times, anywhere in California — as long as you follow the timing and filing rules.
