In This Checklist
Pre-Appeal Checklist
Before you start gathering evidence, complete these preliminary steps:
Initial Research
Evidence Gathering Checklist
This is the most important part. Strong evidence is what wins appeals:
Comparable Sales (Most Important)
Property Record Errors
Condition Documentation (If Applicable)
Additional Evidence (If Applicable)
Organization Checklist
How you present your evidence matters. A well-organized appeal stands out:
Create Your Evidence Package
Pro Tip: Professional Presentation Matters
The assessor reviews hundreds of appeals. A clear, well-organized submission with a professional summary stands out. Don't just throw documents together—take time to organize and present your evidence clearly.
Filing Checklist
Before you submit, make sure you have everything ready:
Before Filing
Timeline Checklist
Here's a suggested timeline for preparing your appeal:
Recommended Timeline
⚠️ Don't Wait Until the Last Minute
Give yourself at least 3-4 weeks to prepare a strong appeal. Rushing leads to weak evidence and missed opportunities. If you file on the deadline and there's an issue, you won't have time to fix it.
Common Mistakes to Avoid
Here are the most common mistakes first-time appellants make:
Using Weak Comparables
Zillow estimates, foreclosures, or properties that aren't truly similar will be rejected. Make sure your comps are truly comparable.
Not Checking Property Record First
Property record errors are the easiest to win on. Always check your property record before doing anything else.
Disorganized Submission
Throwing documents together without organization hurts your credibility. Take time to organize and present professionally.
Filing at the Last Minute
If you file on the deadline and there's an issue, you won't have time to fix it. File at least a week early.
Arguing About Taxes Instead of Value
"My taxes are too high" isn't evidence. You must prove your property's market value is wrong, not complain about tax rates.

Frequently Asked Questions
What do I need to file a property tax appeal?
You need: your property record card, 3-5 comparable sales, documentation of any property record errors, photos of condition issues (if applicable), and a well-organized evidence package. The most important evidence is comparable sales showing similar homes sold for less than your assessed value.
How long does it take to prepare an appeal?
Preparing a strong appeal typically takes 4-8 hours of research and organization. This includes reviewing your property record, researching comparable sales, documenting any issues, and organizing your evidence into a professional presentation.
What is the most important evidence for an appeal?
Comparable sales are the most important evidence. Find 3-5 similar properties that sold recently for less than your assessed value. Property record errors (wrong square footage, room counts, or features) are also very strong evidence and easy to prove.
Do I need to hire someone to file an appeal?
No, you can file an appeal yourself. However, professional help can significantly improve your chances of success, especially if you don't have time for research or aren't comfortable preparing evidence. Many homeowners find the time investment and complexity make professional help worthwhile.
What if I miss something on the checklist?
If you realize you missed something after filing, you typically can't add it later (especially if you filed close to the deadline). That's why it's important to be thorough and file early. Review your complete package before submitting.
How do I know if I have enough evidence?
You have enough evidence if you have: 3-5 strong comparable sales, any property record errors documented, and (if applicable) condition issues with photos and repair estimates. Quality matters more than quantity—strong evidence is better than lots of weak evidence.
Can I use this checklist for a formal appeal too?
Yes, the evidence gathering is similar, but formal appeals (County BOE) also require preparing for an in-person hearing. You'll need multiple copies of all evidence and should practice presenting your case. This checklist covers the evidence gathering, which applies to both informal and formal appeals.
