Jacksonville Florida Tax Guide 2026: No Income Tax, 7.5% Sales Tax, Consolidated City-County

Jacksonville is Florida's largest city by population and land area, and like every Florida city, it charges no state or local income tax — Article VII of the Florida Constitution bars both the state and any local government operating under its authority from taxing personal income. That single fact makes Jacksonville, along with the rest of Florida, one of the most tax-advantaged places in the country for W-2 employees, retirees drawing pension and investment income, and remote workers relocating from high-tax states.

What makes Jacksonville structurally distinctive is its consolidated city-county government. In 1968, the City of Jacksonville merged with Duval County to form a single unified government — one of only a handful of major US cities to do this. Most city services, and the bulk of the property tax millage, are set through this consolidated structure rather than split between separate, sometimes-competing city and county governments. Combined with a 7.5% sales tax and property taxes that are moderate by national standards, Jacksonville's total tax profile sits solidly among Florida's more affordable major metros.

No State or City Income Tax — Florida's Core Advantage

Florida is one of nine US states with no state income tax, and the prohibition is constitutional rather than merely statutory: Article VII, Section 5 of the Florida Constitution bars any tax on the income of natural persons "by the state, or under its authority" — language that extends the prohibition to cities and counties as well, including Jacksonville's consolidated government. Changing this would require a constitutional amendment approved by a 60% supermajority of Florida voters, a high bar that has kept the prohibition firmly in place for decades.

For a single filer earning $75,000, this means Jacksonville residents pay $0 in state and city income tax, versus roughly $2,950 to $4,988 for comparable earners in cities like Milwaukee or Detroit once state and any local income tax are combined. Over a career, this advantage compounds meaningfully, particularly for higher earners and retirees drawing pension, 401(k), or investment income — none of which is subject to Florida income tax.

Jacksonville's Consolidated City-County Government

Jacksonville is structurally unusual among major US cities. In 1968, voters approved consolidation of the City of Jacksonville with Duval County, merging most city and county functions — police, fire, public works, and much of the tax base — into a single government (a handful of smaller municipalities within Duval County, like Atlantic Beach, Neptune Beach, Jacksonville Beach, and the Town of Baldwin, remained independent and levy their own separate, generally lower, municipal millage rates).

Because of this structure, most Jacksonville property owners pay one consolidated set of city-county millage rather than separately stacked city and county levies. For fiscal year 2026-27, the Jacksonville City Council held its maximum millage rate flat at 11.1919 mills — this is the city-county general government portion. Layering on the Duval County Public Schools millage (roughly 6.3 mills) and smaller special-district levies brings the total combined millage for most Jacksonville residents to approximately 17.8 to 19 mills, depending on the specific taxing district.

Duval County's 7.5% Sales Tax

Jacksonville's combined sales tax rate is 7.5%, assembled from two layers:

Florida's discretionary sales surtax is set at the county level and varies statewide from 0.5% to 1.5% (some counties impose none at all); Duval County sits at the top of that range. On $30,000 of annual taxable spending, the 7.5% rate generates $2,250 in sales tax — lower than Chicago (10.25%), Oklahoma City (8.625%), or Sacramento (8.75%), but higher than Miami-Dade County (7%). Florida exempts groceries, prescription drugs, and most medical items from sales tax; the discretionary surtax portion also caps out after the first $5,000 of a single large item purchase (e.g., a vehicle), a Florida-specific nuance that limits the surtax's impact on big-ticket purchases.

Jacksonville Property Tax: Moderate by Florida and National Standards

Jacksonville/Duval County's total millage of roughly 17.8 to 19 mills translates to an effective property tax rate of approximately 1.1% to 1.3% of market value for a typical homesteaded property, after accounting for Florida's Homestead Exemption (up to $50,000 off assessed value for primary residences) and the Save Our Homes cap that limits annual assessment increases to 3% or the CPI, whichever is lower, for homesteaded properties.

On a $400,000 Jacksonville home with homestead exemption applied, annual property tax is approximately $4,000 to $4,800 — moderate compared to Wayne County/Detroit (~$7,440) or Cook County/Chicago, and broadly in line with Miami-Dade. Non-homesteaded properties (investment property, vacation homes) do not benefit from the exemption or the Save Our Homes cap and are assessed closer to full market value, with only a 10% annual assessment increase cap.

Total Tax Burden: Jacksonville vs Detroit vs Sacramento at $75,000

For a single professional earning $75,000 and renting (no direct property tax exposure):

Jacksonville's total burden at this income level is meaningfully lower than both Detroit and Sacramento, driven almost entirely by the absence of any income tax. The gap widens substantially at higher incomes, where California's progressive rates in particular become a much larger factor. For homeowners, Jacksonville's moderate property tax further reinforces its relative affordability among major-metro comparisons.
