Owning a home in Aliso Viejo, California, comes with many perks—beautiful weather, a vibrant community, and proximity to both urban amenities and natural landscapes. However, one aspect of homeownership that can feel less than sunny is paying property taxes. In Aliso Viejo, located in Orange County, property taxes are based on the assessed value of your home, and sometimes that value might not align with what you believe your property is worth. If you suspect your property tax bill is too high due to an inflated assessment, you have the right to appeal it. This blog post will walk you through the process of appealing your property taxes in Aliso Viejo, offering practical tips, timelines, and insights to help you potentially save money.
Why Appeal Your Property Taxes?
Property taxes in Aliso Viejo fund essential services like schools, roads, and emergency response, but that doesn’t mean you should pay more than your fair share. The assessed value of your property, determined by the Orange County Assessor’s Office, directly impacts your tax bill. Under California’s Proposition 13, your property’s assessed value is typically set when you buy it and can only increase by a maximum of 2% annually—unless significant changes like new construction or a change in ownership trigger a reassessment. However, errors can happen. Maybe the assessor overestimated your home’s market value, or perhaps the data used to assess your property is outdated or incorrect. Whatever the reason, an appeal can correct these discrepancies and lower your tax burden.
Appealing your property taxes isn’t just about saving money today; it’s about ensuring fairness for the future. A successful appeal adjusts your property’s base year value or current assessed value, which could lead to savings year after year. With the median home value in Aliso Viejo hovering around $529,385 (as of recent estimates) and a median property tax rate of 1.01%, the average annual tax bill is approximately $5,320. If your assessed value is even slightly off, those dollars can add up fast.
Step 1: Understand Your Property Tax Assessment
Before diving into the appeal process, take a moment to understand how your property taxes are calculated. In Aliso Viejo, your tax bill is based on your property’s assessed value, not necessarily its current market value. The assessed value is established when you purchase your home (the base year value) and is adjusted annually within Proposition 13 limits. However, if the market value of your property drops below the assessed value—say, due to a housing market dip—you can appeal for a temporary reduction under Proposition 8.
Start by reviewing your annual property tax bill, which arrives in the fall from the Orange County Treasurer-Tax Collector. This bill includes your property’s assessed value. You can also check your assessment online via the Orange County Assessor’s website (ocassessor.gov) by entering your parcel number. Compare this value to recent sales of similar homes in your neighborhood. If there’s a significant gap, you might have a case.
Step 2: Gather Evidence to Support Your Appeal
The key to a successful appeal is evidence. The Orange County Assessment Appeals Board (AAB) will want concrete proof that your property’s assessed value is too high. Here’s what you’ll need to collect:
- Comparable Sales Data: Find recent sales of homes similar to yours in Aliso Viejo—same size, age, condition, and location. Websites like Zillow or Redfin can help, but for official records, visit the Orange County Recorder’s Office or Assessor’s website. Aim for sales within the last six months, ideally as close to January 1 (the lien date for assessments) as possible.
- Property Condition Details: If your home has issues like a leaky roof, outdated plumbing, or structural damage that lowers its value, document them with photos and repair estimates. These factors can justify a lower assessment.
- Appraisal Report: Hiring a licensed appraiser to provide a professional opinion of your home’s market value can strengthen your case. While this costs money upfront (typically $300–$600), it could pay off if it leads to significant tax savings.
- Assessment Errors: Double-check the assessor’s records for mistakes—wrong square footage, incorrect number of bedrooms, or misclassified features. You can request your property’s assessment file from the Orange County Assessor’s Office to verify accuracy.
The more detailed and specific your evidence, the better your chances of convincing the appeals board.
Step 3: Contact the Assessor’s Office First
Before filing a formal appeal, try an informal approach. Contact the Orange County Assessor’s Office at (714) 834-2727 or visit their office in Santa Ana (County Civic Center, 200 S. Flower St.). Explain your concerns and present your evidence. Sometimes, the assessor will agree to adjust your value without requiring a formal appeal, saving you time and effort. This step isn’t mandatory, but it’s a smart way to test the waters and potentially resolve the issue quickly.
If the assessor won’t budge, don’t worry—you still have the formal appeal process as your next option.
Step 4: File Your Appeal with the Assessment Appeals Board
If the informal route doesn’t work, it’s time to file a formal appeal. In Orange County, appeals are handled by the Assessment Appeals Board (AAB), an independent panel that resolves disputes between taxpayers and the assessor. Here’s how to do it:
- Obtain the Form: Download the “Application for Changed Assessment” (Form BOE-305-AH) from the Orange County Clerk of the Board’s website (ocgov.com/gov/cob/aab) or pick one up in person at 333 W. Santa Ana Blvd., Santa Ana, CA 92701.
- Complete the Form: Fill out the form with your property details, including the parcel number, your opinion of the property’s value, and the reason for your appeal (e.g., overvaluation, errors in records, or a Proposition 8 decline in value). Attach your evidence as supporting documentation.
- Submit by the Deadline: For regular assessments, file between July 2 and September 15 of the tax year. If you received a supplemental or escape assessment (e.g., after new construction or a missed reassessment), you have 60 days from the notice date to file. Late submissions are rejected, so mark your calendar!
- Pay the Fee: There’s a $30 non-refundable filing fee in Orange County. Include a check or pay online if submitting electronically.
Once filed, you’ll receive a confirmation and a hearing date, though it could take months—or even up to two years—for your case to be scheduled due to backlog.
Step 5: Prepare for Your Hearing
Your appeal hearing is your chance to make your case in person (or virtually, depending on current procedures). The AAB typically consists of three impartial members who will hear from both you and the assessor’s representative. Here’s how to prepare:
- Organize Your Evidence: Bring copies of all documents—comparable sales, photos, appraisals, etc.—and have them neatly organized. You’ll submit these to the board and the assessor’s team.
- Practice Your Argument: Keep it concise and focused. Explain why the assessed value is wrong and how your evidence supports a lower value. Avoid emotional appeals; stick to facts and numbers.
- Understand the Rules: Review the California State Board of Equalization’s “Residential Property Assessment Appeals” guide (Publication 30) at boe.ca.gov for a deeper dive into the process.
You can represent yourself, but if you’re not comfortable, consider hiring a property tax consultant or attorney. Note that anyone other than a spouse, parent, child, or licensed attorney representing you needs written authorization.
Step 6: Attend the Hearing and Await a Decision
At the hearing, you’ll present your case first, followed by the assessor’s response. The board may ask questions, so be ready to clarify your points. After both sides are heard, the AAB will deliberate and issue a decision, usually within a few weeks or months. If they rule in your favor, your assessed value will be adjusted, and you’ll receive a refund for any overpaid taxes (with interest). If they deny your appeal, you can still pay the original bill or explore further legal options, though this is rare.
Important note: You must keep paying your property taxes on time, even with a pending appeal. Failure to do so incurs penalties, but a successful appeal will refund any overpayment.
Additional Tips for Success
- Timing Matters: File as early as possible within the window to avoid missing deadlines. For Proposition 8 appeals (market value declines), monitor Aliso Viejo’s housing market trends annually.
- Check Exemptions: Before appealing, ensure you’re claiming all eligible exemptions, like the Homeowners’ Exemption (up to $7,000 off your assessed value). Apply through the Assessor’s Office if you haven’t already.
- Consider Professional Help: Companies like Ownwell offer property tax appeal services in Aliso Viejo, often on a contingency basis (you pay only if they win). This can simplify the process if you’re short on time or expertise.
What Happens If You Don’t Appeal?
If you skip the appeal process, you’re stuck with the assessor’s valuation—and potentially higher taxes—until the next reassessment opportunity. In a city like Aliso Viejo, where home values can fluctuate, staying proactive ensures you’re not overpaying. Plus, with the AAB’s two-year window to hear cases, your opinion of value might temporarily become the taxable value if delays occur (with some exceptions—check with the Clerk of the Board).

Appealing your property taxes in Aliso Viejo might seem daunting, but it’s a manageable process with the potential for real savings. By understanding your assessment, gathering solid evidence, and following the steps outlined above, you can take control of your tax bill and ensure you’re paying what’s fair.
