Jupiter, FL: Property Tax Guide

The Town of Jupiter's Own Rate: 2.3894 Mills

The Town of Jupiter's proposed and adopted municipal millage rate for FY2026 is 2.3894 mills -- unchanged from both FY2024 and FY2025, per the Town's own published Millage Rate page and its FY2026 budget communications. A mill equals $1 of tax per $1,000 of taxable assessed value, so a home with a taxable assessed value of $500,000 owes roughly $1,195 to the Town itself at that rate. The Town has stated that its own municipal levy makes up only about 13% of a typical Jupiter resident's total property tax bill -- the rest flows to Palm Beach County, the county school district, Palm Beach County Fire Rescue, and any special taxing districts that apply to a specific parcel, all of which set their own rates independently of the Town.

Palm Beach County itself held its countywide millage at 4.5000 mills for FY2026 -- the third consecutive year at that rate, per county budget documentation. That county rate, plus the Palm Beach County School District's own levy (which is typically the single largest line on a Florida property tax bill and was not itemized to a specific current figure in this research pass), plus the Town's 2.3894 mills, plus fire-rescue and any special-district assessments, combine into the total millage that actually applies to a given Jupiter parcel -- and that combined figure varies by exactly which taxing districts overlap a specific address.

The Number Buyers Actually Search For: Effective Rate and Median Bill

Real estate tax-data aggregator Ownwell publishes a city-level effective property tax rate and median annual tax bill for Jupiter, and this page states those figures directly rather than hedging them into meaninglessness. Ownwell's Jupiter, Palm Beach County page -- the incorporated Town of Jupiter this page is actually about -- cites an average property tax rate of about 1.44%, essentially in line with the Palm Beach County average of 1.46%, and an average annual tax bill of about $7,242, well above the county average of $5,533. That figure varies by ZIP code within town limits: 33477 carries both the highest average rate (about 1.47%) and the highest median tax bill (about $6,365) of any Jupiter ZIP, while 33469 carries the lowest average rate (about 1.42%).

It's worth being explicit about a mix-up that's easy to fall into with this exact data source: Ownwell separately publishes a similarly named "Jupiter, Martin County, Florida" trend page -- covering a different, unincorporated Jupiter-addressed area entirely outside Palm Beach County and outside Town of Jupiter limits -- that cites a considerably lower approximately 1.08% effective rate and approximately $5,990 median bill. Those Martin County figures do not describe the Town of Jupiter and shouldn't be quoted as if they do. The honest takeaway for a buyer evaluating the actual Town of Jupiter: expect an effective property tax burden in the rough neighborhood of 1.4%-1.5% of a home's value per year, with a typical annual bill in the $6,000s to $7,000s range for a median-value home, and confirm the exact number for any specific address using the Palm Beach County Property Appraiser's own online tax estimator before finalizing a purchase budget.

A Note on Which County Actually Applies

Nearly all of the incorporated Town of Jupiter sits within Palm Beach County, and the tax figures above reflect that. Property listings and tax-data pages carrying a "Jupiter, FL" mailing address occasionally sit in unincorporated Martin County rather than within Town of Jupiter limits, since USPS ZIP code boundaries and municipal boundaries don't always align in this part of Florida -- Ownwell, for instance, separately publishes distinct Jupiter (Martin County) and Jupiter (Palm Beach County) trend pages, and the two report meaningfully different numbers (roughly a 1.08% effective rate and a $5,990 median bill for Martin County's separate "Jupiter" page, versus roughly 1.44% and $7,242 for the actual Town of Jupiter in Palm Beach County) -- so citing one page's figures as if they describe the other produces a materially wrong number, exactly the trap this page's own effective-rate section above corrects. This page's figures above are for the incorporated Town of Jupiter in Palm Beach County. Anyone evaluating a specific "Jupiter" address should confirm which county and which taxing jurisdiction actually applies to that parcel before assuming the Town of Jupiter's 2.3894 mill rate or Palm Beach County's millage schedule governs it.

Save Our Homes: A Real Cap, but Only for Primary Residences

Florida's Save Our Homes amendment caps the annual increase in a homesteaded property's assessed value -- meaning a genuine, permanent, primary residence with a filed homestead exemption -- at the lesser of 3% or the prior year's change in the Consumer Price Index. For the 2025 tax year, the Florida Department of Revenue set that cap at 2.9%, since CPI growth came in below the statutory 3% ceiling. Over years of ownership, that cap can create a substantial and growing gap between a homesteaded property's taxable assessed value and its true market value -- one of the more valuable tax benefits available to a Florida owner-occupant, and a real reason a long-held Jupiter homestead's tax bill often looks low relative to comparable current listings.

For property without a homestead exemption -- second homes, rental property, and most newly purchased investment property -- Florida's separate non-homestead 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). Critically, that cap does not carry forward to a new owner: Florida law requires non-homestead property to be reassessed at full current market value in the year following a sale, meaning a Jupiter property that's sat under long-term non-homestead ownership, with its assessed value capped well below market for years, will very likely see its assessed value -- and tax bill -- jump substantially in the year after you buy it. Budget for taxes based on the property's likely post-sale reassessed value, not the seller's current, capped assessment shown on a listing.

What This Means When You Budget a Purchase

Three things matter in practice. First, treat the roughly 1.42%-1.47% effective-rate range (averaging about 1.44%) and the roughly $6,365-$7,242 bill figures above as a reasonable planning baseline for a typical Jupiter home, not as the exact number for a specific address -- run an actual estimate through the Palm Beach County Property Appraiser's online tax estimator, which accounts for the exact combination of county, school, town, and special-district millage that applies to that parcel. Second, if the property isn't going to be your primary, homesteaded residence, expect it to reset to full market value the year after you buy it under the non-homestead cap rules, not to inherit the seller's often-lower capped assessment. Third, if you are relocating to Jupiter full-time, file for homestead exemption promptly (Florida's filing deadline is generally March 1 of the qualifying year) and ask the Property Appraiser's office whether any Save Our Homes portability benefit applies if you're transferring a homestead from elsewhere in Florida.
