When I sit down with first-time buyers, or with folks moving up here from out of state, property taxes are almost always the part nobody fully understands. People hear “California taxes” and brace for the worst, or they get a letter in the mail a few months after closing and wonder why there’s a second bill they weren’t expecting.
Here’s the good news: California’s property tax system is actually one of the more predictable ones in the country, once someone explains it to you. The rules are set by law, not by the mood of the market, and that works in a homeowner’s favor.
So let me walk you through how it really works here in Shasta County — no jargon, no scare tactics, just the things I wish every buyer knew before they got the keys.
The 1% Rule, Thanks to Prop 13
Back in 1978, California voters passed Proposition 13, and it still shapes every property tax bill in the state today. The big idea is simple: your general property tax is capped at 1% of your home’s assessed value.
So if you buy a home in Redding for $400,000, your base tax starts right around $4,000 a year. You’ll also see some small voter-approved items on the bill — things like school bonds or local assessments — which is why most homeowners here land somewhere a little above 1% all-in, but not dramatically so.
The other half of Prop 13 is just as important: once your assessed value is set, it can only go up by a maximum of 2% per year, no matter what the market does. That’s the part that protects you. Even in a year when home values jump, the taxable value of your home can’t suddenly leap with it. It’s a slow, steady, predictable climb — which makes budgeting a whole lot easier.
Your Home Gets Reassessed When You Buy It
This is the piece that trips people up the most, so I want to be clear about it.
Your assessed value gets reset to the purchase price when you buy. That means you can’t look at the seller’s current tax bill and assume yours will be the same. If someone has owned their Palo Cedro home since 1995, their assessed value might be a fraction of what you’re paying for it today — and after you close, the county reassesses it at your purchase price.
This isn’t a trick or a penalty. It’s just how the system resets with each sale. The number to plan around is roughly 1% to 1.25% of what you actually paid for the home, not whatever the previous owner was paying.
The Surprise in the Mailbox: Supplemental Tax Bills
If there’s one thing I want buyers to remember from this whole article, it’s this: expect a supplemental tax bill.
Here’s why it happens. The county assessor reassesses your home at your purchase price, but the regular annual tax bill may already have been calculated on the old, lower value. The supplemental bill covers the difference between the old assessed value and your new one, prorated for the months left in the fiscal year (which runs July 1 to June 30).
Shasta County processes roughly 30,000 supplemental tax bills a year, so this is completely routine — but it still catches people off guard because it arrives weeks or months after closing, separate from your normal bill. If your mortgage has an impound account, the supplemental bill is often not included, so you may need to pay it directly. Set aside a little cushion for it and you’ll never be blindsided.
Don’t Forget the Homeowners’ Exemption
This one is easy money, and a lot of people leave it on the table.
If the home is your primary residence, California gives you a Homeowners’ Exemption that knocks $7,000 off your assessed value. It’s not huge — it works out to around $70 a year — but it’s automatic savings for filing a simple, one-time form with the Shasta County Assessor after you buy. There’s no annual renewal as long as you keep living there.
When you close, watch for the exemption claim form, or just call the Assessor’s office at (530) 225-3600 and ask. It takes five minutes and it’s yours for as long as you own and occupy the home.
When Property Taxes Are Actually Due
California splits your annual property tax into two installments, and the dates are the same every year:
The first installment is due November 1 and becomes delinquent after December 10. The second installment is due February 1 and becomes delinquent after April 10. An easy way to remember it: “No Darn Fooling Around” — November, December, February, April.
If you have an impound account through your lender, they handle these payments for you out of your monthly mortgage payment. If you pay taxes on your own, you can view and pay your bill directly through the Shasta County Tax Collector, or call them at (530) 225-5511 with questions.
Prop 19: A Break for Homeowners 55 and Older
One more rule worth knowing, especially if you’re thinking about your next move or helping a parent.
Proposition 19 lets homeowners who are 55 or older (as well as severely disabled homeowners and wildfire or disaster victims) carry their existing low assessed value with them to a new primary residence anywhere in California. You can do this up to three times, and the replacement home has to be purchased within two years of selling your original one.
For a longtime Shasta County homeowner sitting on a low Prop 13 assessment, this can be the difference between feeling stuck and feeling free to right-size into a home that fits this chapter of life — without their tax bill resetting to today’s market value. The rules have some fine print around higher-value homes, so it’s worth talking through with a professional, but the opportunity is real and a lot of folks don’t realize they have it.
The Bottom Line
California property taxes aren’t something to fear — they’re something to plan for. Budget for roughly 1% to 1.25% of your purchase price, expect a supplemental bill after you close, file for your Homeowners’ Exemption, and mark those December and April deadlines on the calendar. Do those few things and there are no surprises.
And if you’re trying to figure out what your taxes would actually look like on a specific home here in Redding, Anderson, Palo Cedro, or anywhere in Shasta County, that’s exactly the kind of thing I’m happy to run through with you before you ever write an offer. No pressure, just honest numbers.
