If you're a Marin County homeowner over 65, a little-known property tax exemption could save you hundreds, sometimes more than a thousand, dollars a year. The catch: the Marin County senior property tax exemption has to be filed by an annual deadline (typically August 1), and many seniors miss it simply because no one told them it existed. If you've recently bought a home or are thinking about selling, here's what you need to know.

What is the Marin County senior property tax exemption?
The exemption lets qualifying homeowners 65 and older waive certain school parcel taxes: the voter-approved assessments that appear as flat line items on your Marin County property tax bill. It does not reduce your base property tax (that's governed by Prop 13), but parcel-tax relief can still add up to real money each year. You generally must reapply or confirm eligibility when a district renews or passes a new parcel tax.
Who qualifies for the senior exemption?
To qualify, you typically must meet three conditions.
You must be 65 or older by July 1 of the tax year you're applying for.
The property must be your primary residence, not a rental or second home.
Apply directly with your local school district, not the County Assessor, by their deadline.
How much can you save?
The amount depends on which school districts assess your parcel. Most Marin seniors save somewhere from $100 to well over $1,000 per year, depending on the number and size of the parcel taxes in their area. Because these taxes are renewed by voters, it's worth re-checking your district's exemption requirements every few years so the savings don't lapse.
Why it adds up
A single Marin parcel can fall under more than one school district (for example, elementary plus high school), and each district can carry its own parcel tax. Waiving several of them in the same year is how the savings reach four figures for many seniors.
How to apply for the Marin County senior exemption
Check your age, ownership status, and that the home is your primary residence.
Each district uses its own application. Contact the district office or check its website. A Marin parcel can fall under more than one district, so you may need to file with each.
Most applications require proof of age (driver's license or birth certificate) and proof of ownership and occupancy. Deadlines are commonly around August 1. Confirm the exact date with each district.
Why this matters for home sellers and buyers
Homeowners 55 and older also have a statewide option to carry their existing low tax base to a new home under California Prop 19.
Don't miss the deadline: plan ahead
Most homeowners who lose out on this exemption do so for one reason: they missed the filing window. If you're closing on a home in Marin or weighing a sale, now is the time to confirm where you stand. Check your district's deadline and file on time so these savings don't slip through the cracks.
