If you own property in Solano County, California, you’re probably familiar with that sinking feeling when the property tax bill arrives. It’s one of those unavoidable expenses that can eat into your budget faster than you’d like. The good news? Understanding Solano County property tax inside and out can help you identify legitimate deductions, appeals opportunities, and strategies to keep more money in your pocket.
Most homeowners in Solano County don’t realize how much control they actually have over their tax burden. Between Proposition 13 protections, exemptions you might qualify for, and the appeals process, there are real opportunities to reduce what you owe. This guide walks you through everything you need to know about Solano County property tax—no jargon, no fluff, just practical strategies from someone who’s helped plenty of folks navigate this exact situation.
How Solano County Property Tax Works
Here’s the reality: Solano County property tax is calculated using a formula that looks simple on paper but has layers worth understanding. Your property tax bill is based on the assessed value of your property, multiplied by the current tax rate (typically around 1% under Proposition 13, plus local voter-approved bonds).
The Solano County Assessor’s Office is responsible for determining the assessed value of every property in the county. They don’t assess based on what your home is actually worth on the open market—they use specific rules, primarily Proposition 13, which caps assessments at 1% of the property’s purchase price and limits annual increases to 2% per year (unless there’s a change in ownership).
Think of it like this: your property assessment is frozen at your purchase price (with that 2% annual bump), regardless of whether your home’s market value doubles. That’s actually the protective part of Proposition 13 working in your favor.
The tax rate itself consists of multiple components:
- Base rate: 1% of assessed value (mandated by Prop 13)
- Voter-approved bonds: Local measures approved by voters for schools, infrastructure, etc.
- Special assessments: District-specific levies for parks, flood control, or other services
Your final bill combines all these pieces. That’s why two homes with similar market values can have different tax bills—it depends on when they were purchased and what bonds/assessments apply to their location.

Understanding Proposition 13 and Your Assessment
Proposition 13, passed in 1978, is the reason your Solano County property tax bill isn’t astronomical. It’s a double-edged protection: your assessment is locked in at purchase price with only that 2% annual increase allowed, but it also means newer homeowners in the same neighborhood often pay wildly different taxes than long-time owners.
Here’s what matters for your situation:
- Purchase price is your base: When you buy, your assessed value equals your purchase price (in most cases). That’s your starting point.
- The 2% rule: Each year, the Assessor can increase your assessed value by up to 2%, even if your home’s market value stays flat or drops.
- Change in ownership triggers reassessment: When property changes hands, it’s reassessed at the new purchase price. This is critical—you can’t avoid it, but you can prepare for the jump in taxes.
- Exclusions exist: Some transfers (like between spouses, or parent-to-child in certain cases) can exclude the property from reassessment under Prop 13’s Proposition 58/63 rules.
Many homeowners don’t realize that Prop 13 protections have limits. If you inherited property or received it as a gift, the reassessment rules might apply differently than you expect. This is where professional guidance matters—misunderstanding these rules can cost thousands.
The California State Assembly website has resources on Prop 13 details, and the Solano County Assessor’s Office (part of the county government) publishes their own guides on how these rules apply locally.
Exemptions and Deductions You Might Qualify For
This is where most homeowners leave money on the table. Solano County property tax exemptions aren’t automatic—you have to claim them. Here are the ones that actually matter:
Homeowner’s Exemption: If your home is your primary residence, you’re likely eligible for a $7,000 exemption (as of recent tax years; amounts can change). This reduces your assessed value, which directly lowers your tax bill. You apply once, and it stays on your property until you sell. If you haven’t claimed this, contact the Solano County Assessor immediately—you might be owed refunds for prior years.
Senior/Disabled Person’s Exemption: If you’re 65 or older, blind, or disabled, you may qualify for additional exemptions that can significantly reduce your tax burden. Income limits apply, so check with the Assessor’s Office.
Welfare Exemption: Non-profit organizations, religious institutions, and certain charitable organizations can claim exemptions. If you own property used for these purposes, this could eliminate your tax liability entirely.
Veteran’s Exemption: Disabled veterans may qualify for exemptions on their primary residence.
Agricultural Land Exemption: If you have farmland in Solano County, you might qualify for agricultural property assessment, which is typically much lower than residential assessment.
The key is this: exemptions reduce your assessed value. A $7,000 exemption saves you roughly $70 per year in taxes (at the 1% rate), but it adds up, and combined exemptions can save hundreds annually.
To apply, contact the Solano County Assessor’s Office directly. They have application forms and deadlines—missing these can cost you.
The Assessment Appeal Process

If you believe your assessed value is wrong, you have options. And this is important: the Assessor’s valuation isn’t gospel. You can challenge it.
When to appeal: You should consider an appeal if:
- Your assessed value seems too high compared to similar homes that sold recently
- Your property has damage or defects that reduce its value
- The Assessor made an error in their records (wrong square footage, wrong number of bedrooms, etc.)
- Your property is in a declining market and your assessment hasn’t adjusted
The timeline matters: In California, you typically have 30 days from receiving your property tax bill to file an appeal with the Assessor. Miss that window, and you lose your right to appeal that year. Mark your calendar when the bill arrives.
How to appeal: You’ll file a written request with the Solano County Assessor’s Office. Include documentation supporting your claim—recent appraisals, comparable sales data, photos of defects, anything that shows the assessed value is too high. Be specific and factual; emotional arguments don’t work here.
The hearing: If the Assessor doesn’t adjust your assessment, you can request a hearing before the Assessment Appeals Board. This is where you present your case. Many people don’t realize they can represent themselves—you don’t need a lawyer, though some folks hire property tax consultants.
Success rates: Appeals succeed regularly. We’re not talking about massive reductions, but even a 5-10% reduction in assessed value saves real money over time. Some folks get 15-20% reductions when they have solid evidence.

How to Calculate Your Tax Bill
Understanding the math behind your Solano County property tax bill helps you spot errors and understand what you’re actually paying for.
Basic formula:
- Start with your assessed value (shown on your tax bill)
- Subtract any applicable exemptions
- Multiply by the tax rate (typically 1.0% plus any voter-approved additions)
- Add any special district assessments
Example: Say your home’s assessed value is $400,000, and you have a $7,000 homeowner’s exemption. Your taxable value is $393,000. At a 1.0% base rate plus 0.25% for voter-approved bonds, your rate is 1.25%. Your tax bill: $393,000 × 0.0125 = $4,912.50 (before special assessments).
Your tax bill statement breaks down all these components. If the math doesn’t add up, contact the Assessor’s Office. Errors happen—wrong exemptions applied, calculation mistakes, outdated property information.
Many homeowners don’t realize they can request a breakdown of their tax bill showing exactly which bonds and assessments are included. This transparency helps you understand where your money goes and can reveal if you’re being charged for a special assessment that doesn’t apply to your property.
Smart Homeowner Savings Strategies
Okay, here’s the practical stuff—actual moves you can make to reduce your Solano County property tax burden:
1. Claim every exemption you qualify for. Start with the homeowner’s exemption if you haven’t already. Then check senior, disabled, veteran, and agricultural exemptions. Each one reduces your assessed value directly.
2. Challenge obvious errors on your property record. The Assessor’s Office uses property records to assess value. If your record says 4 bedrooms but you have 3, or says your lot is an acre when it’s half an acre, that’s a legitimate basis for appeal. Request a copy of your property record and verify everything.
3. Document property defects. Major issues—foundation problems, roof damage, plumbing issues—can justify a lower assessment. Get a professional inspection, document everything, and include it in an appeal. Assessors do consider property condition.
4. Monitor your assessed value year to year. That 2% annual increase should be consistent. If you see a sudden jump that’s not explained by a change in ownership, investigate. Sometimes data entry errors cause unexplained increases.
5. Stay informed about Prop 13 changes. Proposition 13 has been amended several times. Proposition 15 (2020) proposed changes to commercial property assessments. Understanding these helps you plan ahead.
6. Understand special assessments and bonds. Before voting yes on a bond measure, know what it means for your taxes. A $500 million school bond might add $100+ to your annual bill. These are voter-approved, but awareness helps you make informed decisions.
Pro Tip: Keep records of your purchase price, any major renovations, and property improvements. If you ever need to appeal your assessment or defend your home’s value, these documents are gold. They prove your property’s actual condition and value trajectory.
7. Consider your timing on home improvements. Major renovations can trigger a reassessment. This isn’t a reason to skip needed repairs, but it’s worth knowing. A $50,000 kitchen remodel might increase your assessed value by $50,000, which increases your annual taxes by roughly $500 (at 1% rate). Plan accordingly.
Inherited Property and Prop 13 Implications
If you inherited property in Solano County, congratulations—and be prepared for a tax surprise. Inheritance and Solano County property tax interact in ways that catch many people off guard.
The reassessment rule: When you inherit property, it’s typically reassessed at its fair market value at the date of death. This can mean a massive jump in your assessed value and property taxes, especially if the original owner bought decades ago.
Prop 58/63 exclusion: Here’s the good news. California law allows you to exclude inherited property from reassessment if you inherited it from a parent (Prop 58) or grandparent (Prop 63), with some limitations. The property must be your principal residence, or you must use it for agricultural purposes. If you qualify, your parent’s original assessed value (plus 2% annual increases) carries forward—you don’t get hit with the current market value assessment.
What you need to do: This exclusion isn’t automatic. You must file a Claim for Reassessment Exclusion within three years of inheriting the property. Miss this deadline, and you lose the benefit permanently. Contact the Solano County Assessor’s Office immediately if you’ve inherited property.
For more on how inherited property affects your taxes, see our guide on Capital Gains Tax on Inherited Property, which covers federal tax implications alongside state property tax issues.
The emotional side of this: inheriting property is complicated enough without surprise tax bills. Getting the Prop 58/63 exclusion sorted early prevents years of overpaying taxes.
Frequently Asked Questions
What is the current property tax rate in Solano County?
– The base rate is 1.0% of assessed value under Proposition 13. However, your actual rate depends on your location within Solano County and which voter-approved bonds apply to your property. Some areas have additional assessments for schools, fire districts, or other services. Check your property tax bill for your specific rate, or contact the Solano County Assessor’s Office for a breakdown.
Can I appeal my property assessment if I think it’s too high?
– Yes, absolutely. You have 30 days from receiving your property tax bill to file an appeal with the Solano County Assessor’s Office. Provide documentation supporting your claim—comparable sales, appraisals, or evidence of property defects. If the Assessor doesn’t adjust your assessment, you can request a hearing before the Assessment Appeals Board. Many appeals succeed, especially when you have solid evidence.
Do I qualify for the homeowner’s exemption?
– If your home is your primary residence, you likely qualify for the $7,000 homeowner’s exemption (amount may vary). You apply once, and it stays on your property. If you haven’t claimed it, contact the Solano County Assessor immediately—you may be owed refunds for prior years.
What happens to my property taxes if I inherit property from my parent?
– Inherited property is typically reassessed at fair market value, which can increase your taxes significantly. However, Proposition 58 allows you to exclude inherited property from reassessment if you inherited it from a parent and meet certain conditions. You must file a Claim for Reassessment Exclusion within three years. This is critical—missing the deadline costs you thousands in overpaid taxes.
How often can the Assessor increase my assessed value?
– Under Proposition 13, your assessed value can increase by up to 2% per year, regardless of market conditions. This cap applies as long as there’s no change in ownership. When you sell or the property changes hands, it’s reassessed at the new purchase price. The 2% annual increase then applies to the new assessed value.
What exemptions are available besides the homeowner’s exemption?
– Several exemptions exist: Senior/Disabled Person’s Exemption (if you’re 65+ or disabled, with income limits), Veteran’s Exemption (disabled veterans), Agricultural Land Exemption, and Welfare Exemption (non-profits and religious institutions). Each reduces your assessed value. Check with the Solano County Assessor’s Office to see which ones apply to your situation.
Can I deduct my property taxes on my federal income tax return?
– Yes, property taxes are deductible on your federal return, but there’s a cap. The SALT (State and Local Taxes) deduction is limited to $10,000 per year (including state income taxes, local income taxes, and property taxes combined). Most homeowners can deduct their full property tax amount if it’s within this cap. Consult a tax professional for your specific situation, as limits vary based on filing status and income.
What if the Assessor made an error on my property record?
– Request a copy of your property record from the Solano County Assessor’s Office. Check for errors—wrong square footage, incorrect number of bedrooms, inaccurate lot size, etc. If you find errors, report them in writing. Correcting factual errors can reduce your assessed value and justify an appeal. This is one of the easiest ways to lower your taxes legitimately.
Are special assessments for bonds mandatory?
– Yes, voter-approved special assessments are mandatory. These are approved by voters for specific purposes (school bonds, fire district improvements, etc.). They appear as separate line items on your property tax bill. You can’t opt out, but you can vote against future bond measures. Understanding what bonds apply to your property helps you anticipate tax increases.
How do I find out what my home is actually worth for tax purposes?
– Your assessed value is on your property tax bill. However, your home’s market value (what it would sell for today) is likely different. You can check recent comparable sales in your neighborhood through real estate websites like Zillow or Redfin, or hire a professional appraiser. If your assessed value is significantly higher than market value, that’s grounds for an appeal.
What’s the difference between assessed value and market value?
– Market value is what your home would sell for today. Assessed value is what the Assessor determines for tax purposes, typically frozen at your purchase price (plus 2% annual increases) under Proposition 13. In a rising market, your assessed value is usually much lower than market value—that’s Prop 13 protecting you. In a declining market, your assessed value might be higher, which is grounds for an appeal.
Bottom line on Solano County property tax: You have more control over your tax bill than you think. Claim exemptions, challenge errors, understand your assessment, and stay informed about changes. Most homeowners overpay simply because they don’t take these steps. A few hours of effort now can save hundreds (or thousands) over the years you own your home.

If you’re serious about reducing your Solano County property tax burden, start with these three actions today: (1) verify you’ve claimed the homeowner’s exemption, (2) request a copy of your property record and check for errors, and (3) compare your assessed value to recent comparable sales in your neighborhood. From there, you’ll know whether an appeal makes sense.
