Rate Breakdown

Property taxes in Nassau County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Nassau County

In Nassau County, Florida, a property’s tax bill is the product of three key elements: the assessed value, the applicable millage rate, and any exemptions that reduce the taxable base. The Nassau County Property Appraiser determines the assessed value each year by estimating what the property would sell for on the open market, also known as the “fair‑market value.” This assessment is performed as of January 1st and is reviewed annually; however, the value can be adjusted any time if there is a change in ownership, new construction, or a significant improvement.

Once the assessed value is set, the County Clerk of the Courts applies the combined millage rates. A mill is one‑thousandth of a dollar, so a 15‑mill rate means $15 of tax for every $1,000 of assessed value. In Nassau County, the total millage rate includes contributions from the County government, the local school district, the fire district, and any special taxing districts (e.g., community development districts). Because each taxing authority sets its own rate, the overall millage can vary from year to year. The County’s website publishes a detailed breakdown of each component, allowing homeowners to see exactly where their tax dollars go.

Available Exemptions

Florida offers several exemptions that can lower the taxable portion of your property’s assessed value. Nassau County applies the state‑wide exemptions automatically once eligibility is verified by the Property Appraiser.

• Homestead Exemption: Up to $50,000 for a primary residence. The first $25,000 applies to all property taxes, while the additional $25,000 (excluding school taxes) applies only to non‑school portions of the millage.
• Senior Citizen Exemption: Residents 65 years or older may receive an additional $5,000 exemption on the assessed value, plus a “portability” credit if the household income meets the state limit.
• Disability Exemption: Qualifying individuals with a permanent physical or mental impairment can claim a $5,000 exemption, also subject to income qualifications.
• Veteran Exemption: Veterans who have served at least 20 years, or those with a service‑connected disability, may receive a $5,000 exemption. Surviving spouses of veterans who died in service may also qualify.

Application for these exemptions is typically due by March 1st of the tax year. The Property Appraiser’s office provides an online portal and in‑person assistance for filing.

Payment Schedule & Deadlines

Property taxes in Nassau County are billed annually, but they can be paid in two installments to ease cash‑flow concerns.

• First Installment: Due November 1st; a 5 % discount is applied if paid on or before November 30th.
• Second Installment: Due March 1st of the following year. A 3 % discount is available for payments made on or before March 31st.

If you miss a deadline, the discount is lost, and a 10 % penalty plus interest accrues on the unpaid balance. Continued non‑payment can lead to a tax lien, eventual tax sale, or wage garnishment. Nassau County offers an online payment portal, mail‑in options, and in‑person drop boxes for convenience.

Appealing Your Assessment

If you believe your property’s assessed value is inaccurate, you have the right to appeal.

• Step 1 – Review the Notice of Value: The County Property Appraiser sends this notice each spring. Verify the legal description, square footage, and any recent improvements.
• Step 2 – File a Petition: Submit a written petition to the Nassau County Property Appraiser’s Office by July 31st of the tax year. Include supporting evidence such as recent comparable sales, an independent appraisal, or photos of the property’s condition.
• Step 3 – Formal Hearing: If the Appraiser denies the petition, you may request a hearing before the Value Adjustment Board (VAB) by filing a written request within 30 days of the denial.
• Step 4 – VAB Decision: The VAB will hold a public hearing, consider all evidence, and issue a written decision. This decision is final, though further appeal to the circuit court is possible in limited circumstances.

Throughout the process, maintain copies of all correspondence and meet every deadline. Nassau County provides a free “Appeal Kit” and a hotline to guide homeowners through each step.
