Understanding Solano County Taxes
Solano County, located in Northern California between the San Francisco Bay Area and Sacramento, has a unique property tax structure that affects homeowners, investors, and business owners differently. The county assessor’s office determines property values and calculates taxes based on those assessments. If you’re dealing with property taxes in Solano County, you’re subject to California’s property tax system, which is quite different from many other states.
The average effective property tax rate in Solano County hovers around 0.76% of assessed value, though your actual rate depends on your specific location and local bond measures. Unlike states with volatile tax rates, California’s system is relatively stable—but that doesn’t mean you can’t take action to reduce what you owe.
Proposition 13 Basics Explained
Proposition 13, passed in 1978, fundamentally changed how California handles property taxes. This landmark legislation caps the property tax rate at 1% of assessed value and limits annual increases to 2% per year, regardless of market appreciation. This is a major advantage for long-term property owners in California.
Here’s what this means for you: if your home was last assessed at $500,000, your base tax is $5,000. Even if your home’s market value doubles to $1,000,000, your taxes won’t jump dramatically. Instead, they’ll increase by only 2% annually until the property is sold or significantly renovated. When a property changes ownership, it gets reassessed at current market value, which is when taxes can increase substantially.
Understanding Proposition 13 is crucial because it explains why neighboring homes with similar square footage might have vastly different tax bills. The longer you’ve owned your property, the more you benefit from this protection.
How Properties Are Assessed
The Solano County Assessor’s Office conducts property assessments every year, though not every property is physically inspected annually. Assessments are based on several factors: comparable sales, property characteristics (size, age, condition), and improvements you’ve made to the property.

The assessor uses a mass appraisal system that analyzes recent sales of similar properties in your area. If you’ve made significant improvements—like adding a room, installing new plumbing, or upgrading electrical systems—these trigger reassessment and can increase your assessed value. Even cosmetic updates like new paint or landscaping typically don’t trigger reassessment, but structural improvements do.
You have the right to request a property inspection if you believe the assessor’s information is incorrect. The office maintains records on property characteristics, and discrepancies in square footage, lot size, or number of rooms can lead to inflated assessments. If the assessor’s records show your home has four bedrooms when you only have three, that’s grounds for correction.
Calculating Your Tax Bill
Your Solano property tax bill isn’t just the 1% base rate. The calculation includes several components: the base 1% property tax rate, plus voter-approved bonds and assessments for schools, flood control, libraries, and other local services. This is why your effective rate can range from 0.75% to 1.25% or higher depending on your specific location within the county.
Here’s a simplified example: if your home is assessed at $400,000, you’d owe $4,000 in base property tax (1%). But if your area has approved bond measures totaling 0.30%, you’d owe an additional $1,200, bringing your total to $5,200. The county assessor’s website provides a detailed breakdown of all the components included in your bill.
To calculate your specific bill, multiply your assessed value by the combined tax rate (base rate plus all voter-approved assessments). You can find your assessed value on your annual tax bill or by visiting the Solano County Assessor’s website. Comparing your bill year-over-year helps you spot unusual increases that might warrant an appeal.
Available Tax Exemptions
Several exemptions can reduce your Solano property tax burden if you qualify. The homeowners’ exemption provides up to $7,000 in assessed value reduction for owner-occupied homes. This exemption is automatic in most cases, but if you recently purchased property or changed your primary residence, you may need to file a claim.

The disabled persons’ exemption, welfare exemption, and clergy housing exemption are also available. Agricultural land used for farming may qualify for special assessment under the Williamson Act, which can dramatically reduce taxes. Religious institutions, nonprofits, and government properties typically receive exemptions as well.
If you’re a veteran, you might qualify for a disabled veterans’ exemption if your disability is service-connected and rated by the VA. This exemption can provide significant tax relief. Similarly, if you’re over 65 and meet income requirements, you may be eligible for the senior citizens’ property tax deferral program, which allows you to defer taxes until the property is sold or transferred.
Filing an Appeal Process
If you believe your property is overassessed, you have the right to appeal. The Solano County Assessor’s Office accepts appeals during a specific window each year, typically between July 2 and September 15. Missing this deadline means waiting another year to appeal, so mark your calendar.
To file an appeal, you’ll need to submit a form to the Assessor’s Office with supporting documentation. Comparable sales data is your strongest evidence—if similar homes in your neighborhood recently sold for less than your assessed value, that’s compelling proof of overassessment. You can gather this information from real estate websites, county records, or by hiring a professional appraiser.
If the assessor denies your appeal, you can escalate to the Assessment Appeals Board, an independent body that reviews disputed assessments. Many homeowners successfully reduce their taxes through this process. The key is presenting clear, objective evidence that your assessment exceeds fair market value.
Strategies to Lower Taxes
Beyond appeals, several strategies can help reduce your Solano property tax burden. First, ensure you’re claiming all available exemptions. Many homeowners miss the homeowners’ exemption simply because they didn’t file the required form. If you recently purchased a home, check whether the exemption was automatically applied.

Second, monitor your property record with the assessor’s office. Errors in square footage, lot size, or number of rooms are surprisingly common and can inflate your assessment. Request a copy of your property record and verify every detail. If you find discrepancies, file a correction request immediately—this doesn’t require a formal appeal and can be resolved quickly.
Third, consider your improvement timeline carefully. If you’re planning major renovations, timing them strategically around assessment cycles can help minimize tax increases. Consult with the assessor’s office before major work to understand how specific improvements will affect your assessed value.
Fourth, explore whether your property qualifies for special assessments. Agricultural property, timberland, or property in designated areas may qualify for reduced assessments. If your property has multiple uses, you might be able to separate valuations.
Senior and Veteran Programs
California offers specific property tax relief programs for seniors and veterans that many people don’t realize they qualify for. The senior citizens’ property tax deferral program allows homeowners age 62 or older to defer property taxes if they meet income limits. This doesn’t eliminate taxes; instead, they become a lien against the property and are paid when you sell or pass away.
Veterans with service-connected disabilities rated at 50% or more by the VA can claim a disabled veterans’ exemption. The amount varies based on disability rating, but can provide exemptions from $100,000 to $200,000 in assessed value. This is a substantial benefit that many veterans overlook.
If you’re a widow or widower of a veteran who died of a service-connected disability, you may also qualify. The key is understanding which programs apply to your situation and filing the necessary claims with the assessor’s office. These programs require documentation but can provide meaningful tax relief.

Comparing Other California Counties
If you’re considering relocating within California, understanding how property taxes vary by county is valuable. Santa Barbara County property tax rates and assessment practices differ from Solano County, as does Cass County property tax in Missouri for those considering out-of-state moves. Similarly, Town of Huntington property taxes on Long Island have their own unique structure.
While all California counties operate under Proposition 13, local bond measures and assessment practices create variation. Some counties have more aggressive reassessment policies or higher local tax rates. Understanding these differences helps you make informed decisions about property ownership.
Frequently Asked Questions
When is my Solano property tax due?
Solano County property taxes are due in two installments: typically November 1 and February 1. If you miss the deadline, penalties and interest accrue. You can pay online through the county treasurer’s website, by mail, or in person. Many homeowners with mortgages have taxes paid through escrow accounts, so the lender handles payment automatically.
How do I find my assessed value?
Your assessed value appears on your annual property tax bill. You can also access it through the Solano County Assessor’s website by searching your property address. The assessor’s office maintains detailed records including property characteristics, improvements, and assessment history. If you need official documentation, you can request a property record card from the assessor’s office.
Can I appeal my assessment more than once?
Yes, you can appeal annually if you believe your property is overassessed. Each year is a new opportunity to file an appeal during the designated window. If you filed an appeal last year and the assessment changed, you can appeal again if you believe it’s still too high. However, you cannot appeal the same assessment twice in the same year.
What triggers a property reassessment in Solano County?
The primary trigger is a change in ownership. When property transfers to a new owner, it’s reassessed at current market value. Significant structural improvements also trigger reassessment—additions, major renovations, or new construction. Minor cosmetic updates typically don’t trigger reassessment. The assessor’s office can provide guidance on whether specific improvements will affect your assessed value.

Are property taxes deductible on my federal return?
Yes, but with limitations. The Tax Cuts and Jobs Act of 2017 capped the state and local tax (SALT) deduction at $10,000 per year. If your property taxes plus state income taxes exceed $10,000, you can only deduct $10,000 total. This significantly impacts high-tax states like California. Consult a tax professional about how this affects your specific situation.
What’s the difference between assessed value and market value?
Assessed value is what the county assessor determines your property is worth for tax purposes. Market value is what your property would sell for in the current real estate market. Due to Proposition 13, assessed value often lags behind market value for long-term owners. New owners typically have assessed value close to market value. You can appeal if assessed value significantly exceeds market value.
How do I claim the homeowners’ exemption?
If you purchased property recently and the homeowners’ exemption wasn’t automatically applied, you can file a claim with the assessor’s office. You’ll need to provide proof of ownership and that the property is your primary residence. First-time homebuyers should verify the exemption was applied to their first tax bill. The exemption provides up to $7,000 in assessed value reduction.
Conclusion: Taking Action on Your Solano Property Tax
Understanding your Solano property tax situation puts you in control. Whether you’re a new homeowner or have owned property for decades, opportunities exist to reduce your tax burden. Start by verifying your assessed value is accurate, ensuring you’re claiming all available exemptions, and understanding how Proposition 13 protects you from runaway tax increases.
If you believe your assessment is too high, don’t hesitate to file an appeal during the designated window. Gather comparable sales data, document any errors in your property record, and present your case clearly. Many appeals succeed simply because homeowners provide objective evidence that their property is overvalued.
For seniors and veterans, explore whether you qualify for special programs that can defer or reduce taxes. For all property owners, staying informed about local bond measures and assessment practices helps you anticipate future tax changes. Your property tax bill isn’t fixed in stone—it’s a number you can influence through knowledge and action. Consider consulting with a property tax professional or CPA if your situation is complex, especially if you own investment property or have experienced significant market value changes.
