Miami Beach, FL: Property Tax Guide

One Bill, Several Governments

A Miami Beach property tax bill stacks Miami-Dade County's countywide millage, the Miami-Dade County Public Schools levy, the City of Miami Beach's own municipal millage, and potentially special taxing district assessments, all collected together by the Miami-Dade County Tax Collector and then distributed to each taxing authority. Miami-Dade County's total 2025 millage runs approximately 17.59 mills countywide, of which roughly 6.63 mills funds schools, per the Florida Department of Revenue's official county tax rate schedule and the Miami-Dade Property Appraiser's 2025 proposed millage rate table -- and that county-and-school figure applies whether the specific property sits in Miami Beach, unincorporated Miami-Dade, Coral Gables, or any other municipality within the county.

The City of Miami Beach then adds its own rate on top: for fiscal year 2026, the adopted municipal millage is 5.8702 mills for general operating purposes plus a 0.2779 mill debt-service levy tied to the city's general obligation bonds, for a combined city rate of roughly 6.148 mills. Combined with the county/school total, a Miami Beach property owner is generally looking at a combined millage somewhere in the neighborhood of 23-24 mills before any special district is added -- though the exact combined figure for a specific parcel should always be pulled directly from the Miami-Dade Property Appraiser's own online tax estimator, which accounts for the specific taxing districts that apply to that address.

Save Our Homes: Real, but Only for Primary Residences

Florida's Save Our Homes amendment caps the annual increase in assessed value on a homesteaded property -- meaning the owner's actual, permanent, primary residence, with a filed homestead exemption -- 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 below the statutory 3% ceiling, per Save Our Homes guidance published by the Miami-Dade Property Appraiser and other Florida county appraiser offices. Once a homestead exemption is in place, that cap can create a meaningful and growing gap between a property's assessed value (what's actually taxed) and its true market value over years of ownership -- one of the more valuable, if slow-building, tax benefits in Florida real estate.

The catch for Miami Beach specifically: Save Our Homes only applies to a genuine, permanent, primary residence where the owner has filed for and been granted Florida's homestead exemption. A second home, a rental property, an investment condo, or a property owned through certain entity structures generally does not qualify. Given how heavily Miami Beach's inventory skews toward exactly those non-primary-residence use cases -- vacation condos, income properties, pied-a-terres for buyers whose primary residence is elsewhere -- a large share of Miami Beach owners never benefit from Save Our Homes at all, and should not assume a listing's currently assessed value reflects any capped, below-market number.

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

For property that doesn't carry a homestead exemption -- the more typical case in this market -- Florida's separate non-homestead assessment cap, created by a 2008 constitutional amendment (Amendment 1, approved January 29, 2008, with assessments capped starting in 2009), limits the annual increase in assessed value to 10% for county and municipal levies (school board assessments are excluded from this cap and can rise without that limit). That 10% cap applies to second homes, rental property, vacant land, and commercial property alike -- essentially the default protection for most Miami Beach owners, as opposed to the more generous 3%/CPI Save Our Homes cap reserved for homesteaded primary residences.

Critically, the non-homestead cap does not carry over to a new owner the way Save Our Homes portability does. When a non-homestead property sells, Florida law requires the county to reassess it at full current market value in the year following the sale -- the buyer starts a fresh assessment base at market value, with the 10% cap only limiting increases from that point forward. That means a Miami Beach condo that's been under the same non-homestead ownership for a decade, with its assessed value capped well below current market value the whole time, will very likely see a large, one-time jump in assessed value -- and tax bill -- 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.

Portability Doesn't Travel With You to a Second Home

Florida's homestead portability provision lets an owner transfer some or all of their accumulated Save Our Homes benefit from a prior homestead to a new homestead when they move -- but, again, only between primary residences with filed homestead exemptions. It has no application to buying a second home, a vacation condo, or an investment property in Miami Beach while keeping a homestead exemption elsewhere (Florida law only allows one homestead exemption per household, on one primary residence). Anyone relocating to Miami Beach full-time and making it their genuine primary residence for the first time may be able to both file a new homestead exemption and, if applicable, port savings from a prior Florida homestead -- but that requires an actual change in primary residence, not just a purchase. Confirm eligibility and the mechanics of any specific portability transfer directly with the Miami-Dade Property Appraiser's office, since the rules involve specific filing deadlines and documentation requirements this page does not fully enumerate.

No Assessment Smoothing Beyond These Two Caps

Outside of the homestead (Save Our Homes) and non-homestead (10%) caps, Florida performs no other systematic smoothing of assessed value increases -- there's no broader mechanism limiting how much a property's assessed value can move at the point of sale or reassessment beyond what's described above. Miami-Dade County reassesses property values annually (not on a multi-year cycle the way some other states or counties operate), so a property's assessed value is revisited every year, constrained only by whichever cap (if any) applies to it. Given how sharply Miami Beach property values have moved over the past several years -- driven by both broad South Florida price appreciation and building-specific factors like SB 4-D-driven condo pricing dynamics -- that annual reassessment, combined with the post-sale reset to full market value on non-homestead property, is one of the more consequential and least-appreciated facts new buyers here need to understand before finalizing a purchase budget.

What This Means When You Budget a Purchase

Three things matter most in practice. First, don't anchor your tax budget to the seller's current tax bill or currently assessed value -- if the property isn't your future homestead, Florida law resets it to full market value the year after you buy, and that reset can be a large jump from a long-held seller's capped assessment. Second, run an actual estimate for the specific parcel through the Miami-Dade Property Appraiser's online tax estimator, which incorporates the correct combination of county, school, city, and any special-district millage for that exact address -- a blended countywide average is not precise enough for budgeting a Miami Beach purchase. Third, if you intend to make the property your genuine, permanent primary residence, file for homestead exemption promptly (Florida has a filing deadline, generally March 1 of the qualifying year) and ask the Property Appraiser's office directly whether any portability benefit applies from a prior Florida homestead. None of this is tax advice; a Florida real estate attorney or CPA familiar with Miami-Dade property tax specifics should review the numbers on any actual purchase before you rely on them.
