How to Appeal Property Taxes in Jacksonville FL
If your Jacksonville property tax assessment seems too high, you have the right to appeal — and many homeowners who appeal successfully reduce their assessed value by 5–15%, saving hundreds to thousands of dollars per year. In Duval County, the Value Adjustment Board (VAB) hears property tax appeals from August through November each year. This guide walks you through the appeal process step by step.
Understanding Your Assessment
Each year, the Duval County Property Appraiser assesses your property's market value as of January 1st. TRIM notice (Truth in Millage) arrives in August and shows: your property's assessed value, exemptions applied (homestead, etc.), and estimated tax bill. Compare your assessed value to: Recent sales of comparable homes in your neighborhood (same size, condition, and location). Online estimates from Zillow or Redfin (imperfect but directional). Your purchase price (if recent). If your assessed value exceeds what you could realistically sell the property for, you have grounds for appeal. Remember: the Homestead Exemption caps annual assessed value increases at 3% (Save Our Homes cap). If you have homestead, your assessed value may already be well below market value.
The Appeal Process
Step 1: Contact the Property Appraiser's office informally. Sometimes a phone call or email with evidence can result in an adjustment without a formal appeal. Step 2: If informal contact fails, file a formal petition with the Value Adjustment Board (VAB). Deadline: 25 days after TRIM notice is mailed (typically mid-September). Filing fee: approximately $15. Step 3: Prepare your evidence — this is the most important step. You need comparable sales data, photos of property condition issues, and any professional appraisals. Step 4: Attend your VAB hearing. Present your case to a special magistrate. Hearings are informal — no attorney required. Step 5: Receive the magistrate's decision. If you disagree, you can appeal to circuit court (consult an attorney for this step).
Building Your Case
Strongest evidence for appeals: Comparable sales: Find 3–5 homes in your neighborhood that sold near the January 1st assessment date at prices below your assessed value. Match square footage, lot size, condition, and age as closely as possible. Property condition issues: Document deferred maintenance, needed repairs, or condition problems that reduce value. Photos and contractor estimates strengthen your case. Incorrect property data: Check for errors in the appraiser's records — wrong square footage, bedroom/bath count, lot size, or year built. Errors are common and easy to prove. Professional appraisal: A recent appraisal ($400–$600) showing a lower value carries significant weight with the magistrate.
Jacksonville-Specific Tax Details
Duval County millage rate: approximately 19.6 mills (total including county, city, school, and special districts). This means approximately $19.60 per $1,000 of taxable value. Homestead exemption: Up to $50,000 off assessed value. On a $350,000 assessed home: saves approximately $980/year. Must be your primary residence and filed by March 1st. Save Our Homes cap: After the first year of homestead, assessed value increases are capped at 3% or CPI, whichever is less — even if market values rise faster. This creates significant tax savings over time. Portability: When you sell one homestead and buy another in Florida, you can transfer up to $500,000 of your accumulated Save Our Homes benefit to the new property within 3 years.
