Duval County Homestead Exemption: COJ Micro-Guide, Amendment 5 Impact & Tax Rules
Property owners in Jacksonville and Duval County are eligible to reduce their home’s assessed value by up to $51,411 under Florida’s Homestead Exemption laws. Thanks to the passage of Amendment 5, the secondary exemption tier now automatically adjusts for inflation each year.
More importantly, filing for a homestead exemption activates the Save Our Homes (SOH) Cap, limiting your annual property tax assessment increases to 3% or the CPI (whichever is lower). Seniors age 65 and older may also qualify for an additional local exemption of up to $50,000.

How Much Is the Duval County Homestead Exemption? (2026 CPI Updates)
Florida’s homestead exemption is split into two “tiers”. Due to the recent passage of Amendment 5, the second tier is now tied to inflation, meaning your total potential exemption increases each year.
- School Taxes (approx. 5.5 mills): $300,000 − $25,000 (Tier 1 only) = $275,000 taxable value.
- City/County Non-School Taxes (approx. 12.0 mills): $300,000 − $51,411 (Tier 1 + Tier 2) = $248,589 taxable value.
- Estimated Annual Savings: You save roughly $137 on school taxes and $616 on city/county taxes, creating a direct tax bill reduction of over $750 per year.

The “Save Our Homes” (SOH) Cap & Portability (Form DR-501T)
The actual monetary deduction ($51k) is only a small part of the benefit. The true power of the Florida Homestead Exemption is the Save Our Homes (SOH) Cap, which limits your taxable value from rising along with the wild housing market.
1. The 3% SOH Cap
Once your homestead is established, your home’s Assessed Value cannot increase by more than 3% per year or the CPI (whichever is lower). Even if your home’s market value doubles, your property taxes will remain relatively flat.
2. Portability (Moving your Cap)
If you sell your homestead and buy a new primary residence anywhere in Florida, you can transfer your accrued SOH Savings (up to $500,000) to the new property. You must apply for Portability using Form DR-501T alongside your new homestead application.
Duval County Specific Issues: Trusts, Mail-ins & Mistakes
Adding a Spouse or Changing Exemptions (Online Rejection)
The COJ online portal only handles brand new applications. If you got married and need to add a spouse to an existing homestead, or if you are turning 65 and want to add the Senior Exemption to your current homestead, the online system will reject you.
Action Step: You must file in-person at the downtown Forsyth Street office or mail in a paper Form DR-501.
Property Is Held in a Living Trust
Homes held in revocable trusts absolutely qualify, but the trust document must contain specific legal language granting the beneficiary the right to possess and occupy the property.
Action Step: You cannot use the automated portal. You must supply a full copy of the trust or a Certificate of Trust (along with Form DR-501) to the Property Appraiser’s office by mail or in person.
I Missed the March 1 Deadline
Florida law imposes a strict March 1 statutory deadline. However, late applications are accepted by the Duval County Property Appraiser until early September (typically 25 days after the TRIM notices are mailed).
Action Step: You must file your late application in person or by mail, accompanied by a letter explaining the extenuating circumstances that caused you to miss the March 1 deadline. If denied by the appraiser, you can appeal to the Value Adjustment Board (VAB).
Married Couple Living Separately
Florida strictly enforces the rule that a married couple is entitled to only one homestead exemption combined, even if you own two separate houses. The only exception is if you are legally separated or can prove you are entirely financially independent households.
Action Step: If one spouse claims a homestead exemption in another Florida county (or another state), you must file your Duval application in person and provide documentation of financial separation.
Duval County Property Appraiser Office & Map
If you are filing under a Trust, adding an exemption, dealing with portability, or need to submit a paper Form DR-501, you will need to mail documents to or visit the main Property Appraiser’s office in downtown Jacksonville.
Duval County Homestead Exemption FAQs
How much does the homestead exemption save in Duval County?
By exempting the first $25k from all taxes and the inflation-adjusted $26.4k from non-school taxes, the direct tax bill savings is roughly $750 to $850 annually. However, the largest financial benefit is the 3% Save Our Homes cap which prevents massive assessment increases in future years.
What is the deadline to file for a homestead exemption in Duval County?
The statutory deadline is March 1 of the tax year. You must own and occupy the property as your primary residence by January 1. Late filings with “good cause” explanations are accepted until roughly early September.
Do I have to reapply for my Florida homestead exemption every year?
No. Once approved, your Duval County homestead exemption automatically renews every year. The appraiser will mail you a renewal receipt in early January. You only need to notify them if your eligibility changes (e.g., you rent out the home or move).
Can I rent out my homesteaded property in Jacksonville?
Florida law considers renting out your entire homestead as an abandonment of the exemption. You can lose your exemption and face severe penalties, including 15% interest and a 50% penalty on back taxes. Limited short-term rentals (like Airbnb for a few weeks) or renting out a single room while you still live there are subject to strict fractional limits.
What happens to my Save Our Homes cap if I move?
Under Florida’s Portability law, you can transfer your accrued SOH cap savings (the difference between your home’s market value and assessed value, up to $500,000) to a new primary residence in Florida within 3 tax years. You must file Form DR-501T with your new county appraiser.
