Prop 19: How Sacramento Homeowners 55+ Can Take Their Low Property Taxes With Them
If you're 55 or older and you've owned your California home for a while, you're probably sitting on two things: a pile of equity and a beautifully low property tax bill. Proposition 19 lets you keep the second one when you move. Sell your longtime home, buy a replacement anywhere in California — Roseville, Folsom, El Dorado Hills, Davis, anywhere — and transfer your old taxable value to the new house, up to three times in your lifetime. For a homeowner paying taxes on a 1998 assessed value, that can mean saving $5,000–$10,000 or more every single year compared to being taxed on today's price.
Why your tax bill is so low in the first place
Under Proposition 13, your property taxes are based on what you paid for your home (plus a maximum 2% assessed-value increase per year), not what it's worth now. Buy a Sacramento home for $180,000 in 1998, and your taxable value today might be around $310,000 — even if the home would sell for $650,000. That gap is why so many longtime owners feel trapped: selling and buying at today's prices normally means your tax bill gets recalculated on the new purchase price. A $700,000 replacement home would ordinarily mean roughly $8,000+ per year in property taxes instead of the $3,500 you've been paying.
Prop 19 was built to fix exactly that. Since April 1, 2021, homeowners who are 55+, severely disabled, or victims of a governor-declared disaster can transfer their factored base year value to a replacement primary residence anywhere in the state.
How the transfer math works
The rules depend on what your replacement home costs relative to what your old home sold for:
Scenario
What Happens to Your Taxable Value
Replacement costs the same or less than your sale price
Your old taxable value transfers over completely
Replacement costs more than your sale price
Old taxable value transfers, plus the difference in price is added on top
Timing cushion
You can buy up to 105% of your sale price in the first year after selling (110% in the second year) and still get full treatment under the equal-or-lesser rule
Example: you sell your Carmichael home of 30 years for $650,000. Its taxable value is $310,000. You buy a single-story home in Lincoln for $700,000 — $50,000 more than you sold for. Your new taxable value is $310,000 + $50,000 = $360,000. You'll pay taxes on $360,000 instead of $700,000. At a typical 1.1% rate, that's roughly $3,960 a year instead of about $7,700. That's real retirement money, every year, forever (plus the small annual Prop 13 adjustments).
The fine print that actually matters
• Both homes must be your primary residence. No rentals, no vacation homes.
• You get three transfers in your lifetime (disaster victims get one per disaster). Use them wisely.
• Timing: the purchase (or new construction) of the replacement must happen within two years of the sale — before or after.
• File the claim. The transfer isn't automatic. You file with the assessor in the county where the replacement home sits — for most of our area, that's Sacramento, Placer, El Dorado, or Yolo County. File within three years of purchase (sooner is better for full retroactive benefit).
• Only one spouse needs to be 55+ at the time the original home sells.
• ADUs count as part of the residence for qualifying purposes — helpful for multigenerational moves.
The catch nobody advertises: inheriting changed too
Prop 19 gives with one hand and takes with the other. The same law sharply narrowed the old parent-child exclusion. Children who inherit a home now keep the parent's low tax base only if they move in and make it their primary residence within a year — and even then, the exclusion is capped. Inherit mom's house as a rental, and it gets reassessed at market value. If your family's plan involves passing the home down, this deserves a conversation with an estate attorney before you count on the old rules.
Time-sensitive notes (July 2026): Prop 19 base-year transfers apply to sales/purchases on or after April 1, 2021, and claims are filed with the county assessor (Sacramento County posts its forms online). The 105%/110% price cushions and three-transfer limit are current as of this writing. Property tax rates in the Sacramento region typically run ~1.1%–1.25% of assessed value depending on local bonds and assessments. Confirm details with the county assessor or boe.ca.gov/prop19 before acting.
How this pairs with your mortgage
Here's where it gets fun for buyers 55+: your property tax bill is part of your debt-to-income ratio. Transferring a $310,000 taxable value instead of being assessed at $700,000 cuts your monthly tax escrow by hundreds of dollars — which means you qualify for more home, or the same home more comfortably. Pair a Prop 19 transfer with the right loan (conventional, jumbo, or even a strategic reverse mortgage for some downsizers) and the move you thought you couldn't afford often pencils out beautifully. This is also a favorite tool for the buy-before-you-sell crowd: buy the replacement first, sell the old home within two years, and file the claim.
FAQ: Prop 19 base year value transfers
Can I transfer my tax base from another county to Sacramento?
Yes. Prop 19 works statewide — all 58 counties. Bay Area homeowners regularly bring decades-old tax bases to Placer and El Dorado County retirement moves.
What if my new home costs less than my old one sold for?
Even better: your old taxable value simply carries over, and your tax bill may be the lowest of any recent buyer on your street.
Do I have to be retired?
No. Age 55+, severely disabled, or a qualifying disaster victim — employment status is irrelevant.
Can I use Prop 19 on a duplex?
The transfer applies to your principal residence. On a multi-unit property, generally only the portion you occupy as your primary residence qualifies — talk to the assessor about your specific setup.
Does Prop 19 lower my mortgage rate?
No — it lowers your property tax bill, which lowers your total monthly payment and helps your qualifying ratios. Different lever, same happy result.
