If you own property in Marin County, California, you’re probably wondering how much of your paycheck is going toward property taxes—and whether there’s any way to keep more of it. The truth? Marin property tax can feel like a never-ending bill, but understanding the system and knowing your options can save you thousands. This guide walks you through everything you need to know about Marin County property taxes, from how they’re calculated to legitimate strategies that actually work.
Let’s be real: property taxes are one of the biggest expenses homeowners face. In Marin, where home values are sky-high, that tax bill can feel absolutely brutal. But here’s the good news—you’re not powerless. Whether you’re a first-time buyer, a longtime homeowner, or someone considering a move to Marin, knowing the ins and outs of Marin property tax puts money back in your pocket.
How Marin Property Tax Works
Here’s the basic breakdown: your property tax bill in Marin is calculated by multiplying your assessed value by the tax rate. Sounds simple, right? It’s not. The assessed value isn’t what your house is actually worth on the open market—it’s determined by a complex formula that we’ll dig into shortly.
The Marin County Assessor’s Office is responsible for determining the assessed value of every property in the county. Once they set that value, the tax rate is applied. For most Marin homeowners, the base rate is 1% of assessed value, though additional assessments and bonds can push your total rate higher.
Think of it like this: your property tax bill is split between the county, local schools, fire districts, and other special assessment districts. Each one takes a slice of that 1% pie, plus any voter-approved bonds they’ve passed. That’s why your neighbor’s bill might be slightly different from yours, even if your homes are similar.
The key thing to understand is that Marin property tax isn’t just one number—it’s a collection of levies stacked on top of each other. Some of these are mandatory; others are optional assessments for specific improvements or services. Knowing which ones apply to you is the first step toward smart savings.
Pro Tip: Request your full property tax bill breakdown from the Marin County Assessor’s Office. Most homeowners have no idea what portion goes to schools vs. fire districts vs. county services. Once you see it itemized, you might discover you’re paying for assessments you didn’t even know existed.
Proposition 13: The Game You Need to Understand
In 1978, California voters passed Proposition 13, a landmark law that fundamentally changed how property taxes work in the state—and it still affects your Marin property tax bill today. Here’s what it did: it capped the property tax rate at 1% of assessed value and limited assessment increases to 2% per year, regardless of how much your home’s market value actually increased.
This sounds great in theory—and it was a huge win for homeowners when it passed. But here’s where it gets complicated: when you buy or sell property, the assessed value is reset to the current market value. So if you buy a $2 million home in Marin, your assessed value starts at $2 million, and your property tax bill reflects that. But if you’ve owned the same home for 20 years and it’s now worth $3 million, your assessed value might still be closer to $1.5 million, meaning you’re paying way less in taxes than a new buyer with a similar home.
This creates a bizarre situation where two nearly identical homes on the same street can have wildly different tax bills. It’s not unfair to the long-term homeowner—it’s actually a major benefit. But it means you need to understand your own assessed value and how it compares to your home’s actual market worth.

Warning: If you’re buying property in Marin, don’t assume your taxes will stay the same. Proposition 13 resets the assessed value at purchase, so your bill will jump to reflect current market prices. Factor this into your affordability calculations.
Assessment and Valuation in Marin County
The Marin County Assessor determines your property’s assessed value using several methods. For residential properties, they typically use the market approach—comparing your home to recent sales of similar properties in your area. They also consider the income approach (if it’s a rental property) and the cost approach (replacement value).
Here’s what most people don’t realize: the assessed value is supposed to reflect the market value, but there’s always a lag. The assessor uses sales data from the previous year or two, so your assessment might not reflect the absolute current market. If your home’s market value has dropped significantly, you might be paying taxes on an inflated assessment.
The Marin County Assessor’s Office sends out assessment notices annually. When you receive yours, don’t just file it away. Actually look at it. Compare the assessed value to recent comparable sales in your neighborhood. If you think the assessment is too high, you have the right to appeal—and many homeowners successfully do.
Your property’s assessed value includes the land and the structures on it. The assessor will have detailed information about your home’s square footage, year built, number of bedrooms, condition, and any improvements you’ve made. If you’ve added a deck, renovated your kitchen, or built an accessory dwelling unit (ADU), the assessor will likely have recorded it, and it will affect your assessment.

Exemptions and Deductions You Might Qualify For
This is where real money can be saved. California offers several property tax exemptions and deductions that many Marin homeowners either don’t know about or mistakenly think they don’t qualify for. Let’s break down the main ones:
- Homeowners’ Exemption: If you occupy your home as your principal residence, you may qualify for a $7,000 exemption on the assessed value. This reduces your taxable value and, therefore, your annual bill. Many people forget to file for this, or they don’t realize they still qualify after moving.
- Disabled Veterans Exemption: Veterans with service-connected disabilities may qualify for an exemption of $100,000 to $200,000 of assessed value, depending on disability rating. This is a substantial savings and is often overlooked.
- Welfare Exemption: Non-profit organizations, churches, and certain charitable organizations may qualify. For more on this, see our guide on Do Churches Pay Property Taxes.
- Agricultural Land Exemption: If you own farmland or vineyard property in Marin (yes, this exists), you may qualify for lower assessments based on agricultural use value rather than market value.
- Accessory Dwelling Unit (ADU) Exemption: California recently passed laws allowing property tax exemptions for newly constructed ADUs on single-family residential properties. If you’re thinking about adding an ADU to generate rental income, this could significantly reduce the tax impact.
The key is filing the right forms with the Marin County Assessor. Most exemptions require you to submit an application; they don’t happen automatically. And some have deadlines—miss them, and you lose the benefit for that year.
Pro Tip: If you’ve recently retired or become disabled, check immediately whether you qualify for exemptions. Many people discover years later that they could have been saving money but didn’t file the paperwork. The assessor’s office can sometimes grant exemptions retroactively, but it’s not guaranteed.
Special Programs for Senior Homeowners
California recognizes that fixed-income seniors can be hit hard by rising property values and Marin property tax bills. Several programs exist specifically to help:
- Property Tax Postponement: Homeowners 65 and older, or blind or disabled property owners of any age, may be able to postpone property taxes until the home is sold or transferred. This doesn’t eliminate the tax—it defers it. But for seniors on tight budgets, it can be a lifesaver.
- Prop 19 Rules for Inherited Property: If you inherited property from a parent or grandparent, you may be able to transfer their lower assessed value to your new property (up to $1 million). This is a complex rule, but it can result in massive tax savings if you qualify.
- Senior Citizen Property Tax Assistance Programs: Marin County offers various assistance programs for low-income seniors. Contact your local city or the Marin County Social Services Department to see what’s available.
These programs are often underutilized because seniors don’t know they exist. If you’re over 65 and own property in Marin, spend an hour researching these options. It could save you thousands annually.
How to Appeal Your Property Tax Assessment
If you believe your property’s assessed value is too high, you have the right to appeal. This is one of the most underused tools for reducing Marin property tax bills, and it works surprisingly often.
Here’s the process:
- File a Formal Assessment Appeal: You must file within 30 days of receiving your assessment notice. The form is available from the Marin County Assessor’s Office or online.
- Gather Evidence: Compile comparable sales data for similar homes in your area that sold for less than your assessed value. You’ll also want documentation of any property defects, deferred maintenance, or issues that would lower value (like proximity to a highway, poor school district, etc.).
- Submit Your Case: Present your evidence to the Assessor’s Office. Many appeals are resolved at this level without needing to go further.
- Attend the Assessment Appeals Board Hearing (if necessary): If the assessor doesn’t reduce your assessment, you can request a hearing before the county’s Assessment Appeals Board. This is a formal hearing, but you don’t need a lawyer. Present your comparable sales data and explain why you think the assessment is too high.
The success rate for appeals in Marin County is actually quite good—especially if you have solid comparable sales data showing that similar homes sold for less. Even a reduction of $100,000 in assessed value saves you about $1,000 per year in property taxes. That’s worth a few hours of work.
Pro Tip: Time your appeal strategically. If your area has recently experienced a downturn in home values, file an appeal immediately. If you know your home has deferred maintenance or significant issues, document them with photos and repair estimates. The more concrete your evidence, the better your chances of success.
Smart Planning Strategies to Reduce Your Tax Burden
Beyond appeals and exemptions, there are longer-term strategies to consider:
- Understand the Step-Up in Basis: If you’re estate planning, know that heirs receive a “step-up in basis” when they inherit property. This means their assessed value resets to the market value at the time of death, not the original purchase price. This is a huge benefit for heirs and should factor into your estate planning.
- Consider a 1031 Exchange: If you’re selling investment property, a 1031 exchange allows you to defer capital gains taxes by reinvesting in similar property. While this doesn’t directly reduce Marin property tax, it can help you preserve wealth that would otherwise go to federal taxes.
- Evaluate ADU Potential: Adding an ADU can increase your home’s value and, therefore, your assessed value. But the recent ADU exemption law might offset this. Run the numbers before investing.
- Document Home Improvements Carefully: When you make improvements, keep receipts and documentation. The assessor will find out about major renovations anyway (through permit records), but minor improvements that don’t require permits might fly under the radar. This isn’t about being dishonest—it’s about not volunteering information that increases your tax bill.
- Monitor Your Neighborhood’s Sales: Stay aware of what comparable homes are selling for. If prices are dropping, that’s your signal to file an appeal. If prices are rising, accept that your assessed value will eventually catch up (up to 2% per year).

One more resource: the IRS Tax Topic 503 covers deductibility of state and local property taxes, which is important if you itemize deductions on your federal return. The $10,000 SALT (State and Local Tax) deduction cap means you might not get full tax benefit from your Marin property tax payment, but it’s worth understanding.
Frequently Asked Questions
What is the current property tax rate in Marin County?
– The base rate is 1% of assessed value under Proposition 13, but your total effective rate is usually higher when you include county, school district, fire district, and special assessment levies. Most Marin homeowners pay between 1.1% and 1.3% of assessed value annually, though this varies by specific location and which special districts apply to your property.
Can I deduct Marin property taxes on my federal income tax return?
– Yes, but with a major caveat. You can deduct state and local property taxes (SALT) on your federal return if you itemize deductions. However, the total SALT deduction is capped at $10,000 per year. For many Marin homeowners with high property tax bills, this means you can’t deduct the full amount. Consult a tax professional to see if itemizing makes sense for you.
How often is my property reassessed in Marin County?
– Your property is assessed annually. However, the assessed value can only increase by 2% per year under Proposition 13, unless your property changes ownership or you make major improvements. When you buy or sell, the assessed value is reset to current market value.
What happens to my property taxes if I make major renovations?
– Major renovations that require permits will trigger a reassessment. The assessor will add the value of the improvement to your assessed value. However, some improvements (like painting or routine maintenance) don’t require permits and won’t affect your assessment. Always check whether a project requires a permit before starting.
Is the homeowners’ exemption automatic, or do I need to apply?
– You must apply. The $7,000 homeowners’ exemption doesn’t happen automatically. File the application with the Marin County Assessor’s Office when you buy your home or claim it for the first time. If you’ve owned your home for years and never applied, you may be able to get it retroactively, but don’t count on it—apply now.
What should I do if I disagree with my property’s assessed value?
– File an appeal with the Marin County Assessor’s Office within 30 days of receiving your assessment notice. Gather comparable sales data showing that similar homes sold for less, and submit your evidence. If the assessor doesn’t reduce your assessment, request a hearing before the Assessment Appeals Board.
Are there property tax breaks for disabled veterans in Marin County?
– Yes. Disabled veterans with service-connected disabilities may qualify for exemptions ranging from $100,000 to $200,000 of assessed value, depending on their disability rating. This is a substantial benefit and should be pursued immediately if you qualify. Contact the Marin County Assessor’s Office or your local Veterans Affairs office for details.
What is Proposition 13, and how does it affect my Marin property tax bill?
– Proposition 13, passed in 1978, caps property tax rates at 1% of assessed value and limits annual assessment increases to 2% per year. This benefits long-term homeowners (your taxes don’t skyrocket as your home’s value increases) but can disadvantage new buyers (your assessed value resets to current market value at purchase). Understanding Prop 13 is essential to understanding why your neighbor might pay very different taxes than you.
Can I postpone my property taxes if I’m a senior?
– Yes. California’s Property Tax Postponement Program allows homeowners 65 and older (or blind or disabled property owners of any age) to postpone property taxes until the home is sold or transferred. This defers the tax rather than eliminating it, but it can provide relief for seniors on fixed incomes.
