Amelia Island / Fernandina Beach, FL: Property Tax Guide

The Headline Numbers: What Ownwell Actually Publishes for This Market

Ownwell's published city- and county-level property tax data gives a specific, sourced answer to the question most buyers actually ask: what does property tax typically cost here. Fernandina Beach's median effective property tax rate is 1.05% of assessed value -- lower than the Florida state median of about 1.10%, but higher than the national median of about 1.02%. The average Fernandina Beach homeowner pays approximately $5,471 per year in property taxes, against a county-wide average of $3,789. Fernandina Beach also carries the highest effective rate of any community tracked within Nassau County in Ownwell's data, with the county's median effective rate at about 0.94% overall and the low end of the county (Bryceville, an inland community) running closer to 0.65%. Ownwell separately notes an average (as opposed to median) property tax rate for Fernandina Beach of 1.34%, against a county average of 1.24% -- the gap between the median and average figures reflects the wide range of assessed values and exemption status across the city's housing stock, from modest inland homes to multi-million-dollar oceanfront estates.

Median home value matters directly here too: Fernandina Beach's median home price, per the same Ownwell dataset, is $500,460 -- the highest of any community within Nassau County -- against a county-wide median of $350,448. That higher median value is a real part of why Fernandina Beach's average tax bill runs above the county average even though its effective rate (1.05%) is not dramatically higher than the county's (0.94%): a higher-value housing stock generates a higher dollar bill even at a similar or modestly higher rate. State this plainly rather than the way some competing sites do: expect a Fernandina Beach property tax bill in the neighborhood of $5,000-$5,500 per year for a property at or near the city's median value, understanding that any specific parcel's bill depends on its own assessed value, homestead status, and exact taxing district.

The Millage Layers: County, School, and City

Nassau County's 2025 total millage runs approximately 13.28 mills, with roughly 6.35 mills of that funding the county's school district, per Nassau County Property Appraiser-sourced reporting. That county-and-school figure applies to every property in Nassau County regardless of whether it sits inside Fernandina Beach city limits or in unincorporated county land like the Amelia Island Plantation/Summer Beach area to the island's south. Properties inside Fernandina Beach city limits then have the city's own municipal millage added on top: for FY2025-26, the City Commission's tentative 4.6849-mill rate (a 7.37% increase over rollback, per Fernandina Observer reporting) went through a required re-adoption process after the Florida Department of Revenue flagged advertising errors in the city's Truth in Millage (TRIM) notices. Looking ahead, for FY2026-27 the City Commission voted 4-1 to set an even higher tentative millage of 4.8530 mills -- the highest of four options city staff presented, and a roughly 3.6% increase over the prior year's 4.6849-mill rate -- projected to generate about $24.7 million in property tax revenue, per Fernandina Observer reporting. As with any tentative rate, commissioners can lower it during the September budget hearings but cannot raise it above 4.8530 mills, so the final, adopted FY2026-27 city millage should be confirmed directly with the City of Fernandina Beach once budget hearings conclude rather than assumed from this tentative figure. A property in unincorporated Nassau County -- inside the Amelia Island Plantation/Omni Resort area or Summer Beach, for instance -- pays only the county-and-school millage, with no separate city layer, which is a real, structural tax difference buyers should understand when comparing a city-limits property to a south-island unincorporated one.

Homestead Exemption and Save Our Homes: Real Savings, With Real Limits

Florida's standard $50,000 homestead exemption applies to a genuine, permanent, primary residence with a filed homestead application, and per Nassau County Property Appraiser-sourced guidance, that exemption saves a qualified Nassau County homeowner more than $700 per year. Beyond the flat exemption, Florida's Save Our Homes amendment caps the annual increase in assessed value on a homesteaded property at the lesser of 3% or the prior year's Consumer Price Index change -- for the 2025 tax year, the Florida Department of Revenue set that cap at 2.9%, since CPI growth came in just below the statutory 3% ceiling. On a hypothetical homesteaded $350,000 Nassau County home with the standard $50,000 exemption applied, one sourced example calculation lands near $4,141 per year in tax, or roughly $345 per month -- illustrative of the mechanics, not a promise about any specific parcel's actual bill.

The catch, as in every Florida coastal market, is that Save Our Homes only benefits a genuine primary residence with a filed homestead exemption -- not a second home, a vacation property, or a straightforward rental investment, all of which are common purchase types on Amelia Island given its resort character. A long-time owner with years of accumulated Save Our Homes protection can have an assessed value sitting well below current market value, which means their listed tax bill is not a reliable predictor of what a new, non-homesteading buyer will actually owe after purchase.

The Non-Homestead Reality for Second Homes and Investment Property

For property that doesn't carry a homestead exemption -- the more common case for Amelia Island purchases given how much of the market is second-home, resort, and investment-oriented -- Florida's separate non-homestead assessment cap, created by a 2008 constitutional amendment, limits the annual increase in assessed value to 10% for county and municipal levies (school-board assessments are excluded from that cap). Just as importantly, that cap does not travel with a new owner: Florida law requires a non-homestead property to be reassessed at full current market value in the year following a sale, meaning a seller's long-held, capped assessed value is not a reliable guide to what a buyer's own post-purchase bill will look like. A Fernandina Beach or Amelia Island property that has been under the same non-homestead ownership for years, with an assessed value well below current market value, will very likely see a real, one-time jump in assessed value -- and tax bill -- in the year after a sale closes.

What This Means for Budgeting a Purchase

Three practical takeaways. First, use the city- and county-level figures above as the honest starting reference point: expect roughly 1.05% of assessed value annually for a Fernandina Beach city-limits property, or roughly 0.94% county-wide, understanding that any specific parcel's actual bill depends on its own assessed value and taxing district. Second, don't anchor a budget to a seller's current tax bill if the property won't be your homestead -- plan for a reassessment to full market value in the year following the sale. Third, run an actual estimate for the specific parcel through the Nassau County Property Appraiser's own records and tools, which will show the correct combination of county, school, and (if applicable) city millage for that exact address, rather than relying on a blended city- or county-wide average for a purchase decision. None of this is tax advice; a Florida real estate attorney or CPA familiar with Nassau County specifics should review the numbers on any actual purchase before you rely on them.
