Surfside, FL: Property Tax Guide

One Bill, Several Taxing Authorities

Every property in Surfside sits inside Miami-Dade County and is subject to the same countywide general-fund millage and Miami-Dade County Public Schools levy as any other property in the county, regardless of which of the county's dozens of cities and towns it happens to sit in. For FY2025, that combined county-plus-school figure runs approximately 17.59 mills, of which roughly 6.63 mills funds schools, per the Florida Department of Revenue's official county tax rate comparison table -- a number that applies identically whether the parcel is in Surfside, Bal Harbour, Miami Beach, or unincorporated Miami-Dade.

On top of that countywide base, the Town of Surfside adds its own municipal millage, since Surfside is an independent incorporated town with its own budget and its own elected Town Commission rather than an unincorporated area governed only by the county. This research pass could not independently confirm the current specific figure for Surfside's own town-level millage rate for the current fiscal year -- it is real and it does apply, but a precise, current number should come from the Miami-Dade County Property Appraiser's own online tax estimator for a specific parcel, which correctly layers in the town rate along with any special-district assessment that applies to that exact address, rather than from a general estimate on this page.

What an Aggregator's Effective Rate Actually Tells You

Ownwell, a property-tax-tracking service, publishes a median effective property tax rate for Surfside near 1.60% of assessed value, compared with a roughly 1.94% average across Miami-Dade County as a whole -- meaning Surfside runs somewhat below the countywide average on this particular measure, according to that aggregator's own tracked data. This is a useful sanity check for roughly what share of a property's value ends up as an annual tax bill, but it is not the same thing as an official published millage rate, and it blends together homesteaded and non-homesteaded properties whose actual bills, relative to true market value, can differ enormously because of Florida's assessment caps described below. Treat it as a directional data point, not a number to plug into a purchase budget without verification.

Save Our Homes: A Real Cap, but Only for a Genuine Primary Residence

Florida's Save Our Homes constitutional amendment caps the annual growth in assessed value on a homesteaded property -- meaning an owner's actual, 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 applicable cap came in at 2.9%, since CPI growth landed below the 3% statutory ceiling, per Save Our Homes guidance published by Florida county property appraiser offices. Over years of ownership, that cap can open a significant, growing gap between a homesteaded property's assessed value (what's actually taxed) and its true market value -- a genuinely valuable, if slow-building, benefit.

The catch, and it's a real one in a market like Surfside: Save Our Homes only applies to a genuine, permanent, primary residence with an actual filed homestead exemption. A second home, a seasonal condo, a rental unit, or a property held through certain entity structures does not qualify. Given how much of Surfside's small, condo-heavy inventory serves as a second home, an investment property, or a seasonal residence for owners whose primary home is elsewhere, a substantial share of buyers here should plan around never receiving this particular tax benefit, and should not assume a seller's currently assessed value -- which may reflect years of capped growth under a homestead exemption -- carries over to them.

The Non-Homestead 10% Cap: The One That Actually Applies to Most Buyers Here

For property without a homestead exemption -- the more typical case for a Surfside condo purchase -- Florida's separate non-homestead assessment cap, created by a January 2008 constitutional amendment, limits the annual growth in assessed value to 10% for county and municipal levies (school-board assessments are excluded from this particular cap). That 10% cap is the default protection for second homes, rental property, and investment condos across the state, Surfside included, as opposed to the more generous 3%/CPI Save Our Homes cap reserved for a true primary residence.

The important mechanic for a buyer: the non-homestead cap does not transfer to a new owner. Florida law requires the county to reassess non-homestead property at full current market value in the tax year following a sale, meaning the buyer's assessment resets to market value at closing, with the 10% cap only limiting growth from that new starting point forward. A Surfside condo held by the same non-homestead owner for a decade, with its assessed value capped well below current market value the entire time, will very likely see a substantial jump in assessed value -- and tax bill -- in the year after a sale closes. Budget for the property's likely post-sale reassessed value, not the seller's current, capped bill shown on a listing sheet.

Homestead Portability, and Why It Rarely Applies to a Second Home Here

Florida's portability provision lets an owner carry some or all of an accumulated Save Our Homes benefit from a prior homestead to a new one when they move -- but only between genuine primary residences with filed homestead exemptions, and Florida law permits only one homestead exemption per household at a time. That means portability generally has no application to purchasing a Surfside unit as a second home, vacation property, or investment while keeping a homestead exemption on a primary residence elsewhere. A buyer relocating to Surfside full-time and making it their genuine, permanent primary residence for the first time may be able to both file a new homestead exemption and, if eligible, port savings from a prior Florida homestead -- but that requires an actual, bona fide change in primary residence, documented and filed, not simply a purchase closing. Confirm eligibility and filing deadlines (generally March 1 of the qualifying year) directly with the Miami-Dade County Property Appraiser's office.

What This Means When You Budget a Purchase

Three practical points matter most. First, do not anchor a tax budget to the seller's current bill or currently assessed value -- if the unit will not be your homestead, Florida law resets it to full market value the year after closing, and that reset from a long-held seller's capped assessment can be a large, one-time jump. Second, run the actual parcel through the Miami-Dade County Property Appraiser's online tax estimator, which correctly layers county, school, Surfside's own municipal rate, and any applicable special district for that specific address -- a countywide average or an aggregator's effective-rate figure is not precise enough on its own for a purchase budget. Third, if the unit will become a genuine, permanent primary residence, file for homestead exemption promptly and ask the Property Appraiser's office directly whether portability from a prior Florida homestead applies. None of this is tax advice; a Florida CPA or real estate attorney familiar with Miami-Dade property tax mechanics should review the actual numbers before you rely on them for a purchase decision.
