Miami Luxury Home Property Taxes 2026: Rates & Strategy
Miami luxury home property taxes run close to 1% of market value on average in Miami-Dade County for 2026, but the real range spans roughly 0.6% to over 2% once you factor in homestead status, millage overlays, and non-ad valorem assessments — and that spread is where most new owners get blindsided in year two.
- Miami luxury home property taxes average close to 1% of market value in Miami-Dade County for 2026, but non-homestead owners pay the full uncapped rate.
- Homestead Exemption caps assessed value growth at 3% a year under Save Our Homes — Buy this if the property is your primary residence.
- Portability lets Florida homestead owners carry up to $500,000 of accumulated tax savings into a new luxury purchase — Consider it before you list.
- Non-resident and foreign buyers get no homestead break and should budget the full millage rate, typically 19 to 21 mills combined.
- A Value Adjustment Board appeal on an over-assessed $5M waterfront estate can cut $8,000 to $15,000 off an annual bill — file it every cycle.
Why this matters
A $6M waterfront estate in Miami Beach and a $6M waterfront estate in Golden Beach can carry tax bills $20,000 apart depending on which municipality, school district, and special taxing overlay sit under the property. Kelby Contreras walks buyers through this before contract, not after closing, because the county mails the real bill in November — long after the excitement of the purchase has worn off. Preconstruction condo buyers get hit hardest: the assessed value resets to the purchase price the first full tax year, which means a unit bought at $3.2M in 2026 gets taxed on $3.2M, not on the developer's pre-sale price from two years earlier.
Who this is for
This guide is built for buyers, owners, and investors moving $1M-plus properties through Miami-Dade, Broward, and Palm Beach — primary residents chasing the homestead exemption, non-resident and international buyers who get none of it, and investors weighing preconstruction condos against resale waterfront stock. If you're comparing neighborhoods or structuring a purchase around tax exposure, Kelby Contreras advises on the assessment math before you write an offer, not after the first bill arrives.
What to look for in Miami luxury home property taxes
The millage rate stack
Every Miami-Dade property gets taxed by a stack of overlapping millage rates — county, city, school district, and special districts like South Florida Water Management — that combine into one number, typically 19 to 21 mills depending on municipality. A mill is $1 per $1,000 of assessed value, so a $4M assessed property at 20 mills owes roughly $80,000 before exemptions. The city layer matters most: Miami Beach, Coral Gables, and Bal Harbour each set their own rate, and the gap between them on a comparable property can run several thousand dollars a year.
Homestead exemption eligibility
Only a primary Florida residence qualifies for the homestead exemption, which knocks up to $50,000 off assessed value and, more importantly, unlocks the Save Our Homes cap. Non-resident owners, LLC-titled properties, and second homes get none of it — the full assessed value is taxable from day one. If a luxury buyer plans to make Miami their primary residence, filing by March 1 of the following year is the single highest-leverage move on this list.
Save Our Homes cap vs. the 10% non-homestead cap
Homestead properties get assessed value growth capped at 3% annually or the Consumer Price Index, whichever is lower — a real ceiling in a market where luxury values have climbed double digits some years. Non-homestead properties, including most investment condos and second homes, get a 10% annual cap instead, which still lets a $3M assessment climb $300,000 in a single year. This gap alone can separate a $28,000 tax bill from a $52,000 one on identical properties five years after purchase.
Non-ad valorem assessments
Waterfront and coastal luxury properties often carry non-ad valorem line items that sit outside the millage calculation entirely — drainage district fees, seawall maintenance assessments, and in some Broward and Palm Beach communities, CDD bonds tied to infrastructure. These show up as flat dollar charges on the same bill and can add $1,500 to $6,000 a year depending on the community, regardless of the home's assessed value.
Portability of accumulated savings
Florida allows homestead owners to transfer up to $500,000 of accumulated Save Our Homes savings from a sold home to a new one within two years, known as portability. For an owner who's held a property for a decade with a large gap between assessed and market value, this can mean tens of thousands in annual savings carried straight into the next purchase — but it has to be filed, it doesn't happen automatically.
The assessment appeal window
Miami-Dade mails the Truth in Millage (TRIM) notice in August, and property owners have roughly 25 days from that date to file a Value Adjustment Board petition disputing the assessed value. Miss that window and the assessment stands for the full tax year regardless of how far off it is from comparable sales.
Top strategies for managing property taxes on a Miami luxury home
Homestead Exemption — the baseline play. One spec that matters: up to $50,000 off assessed value plus the 3% Save Our Homes cap once filed. On a $2.5M primary residence, that's the difference between paying tax on $2.5M this year and being capped near $2.06M five years later if the market runs hot. Buy — file by March 1 if the property will be your primary residence.
Portability — the veteran move. One spec that matters: up to $500,000 in accumulated savings transferable within a two-year window of selling a prior Florida homestead. An owner moving from a $1.8M Coral Gables home into a $4.5M Fort Lauderdale waterfront property can carry years of capped assessment straight into the new tax bill. Consider it seriously if you've owned a Florida homestead for more than five years before upgrading.
Value Adjustment Board appeal — the underused lever. One spec that matters: a successful appeal on an over-assessed $5M estate has cut $8,000 to $15,000 a year in documented Miami-Dade cases where comparable sales supported a lower value. Most luxury owners never file because the 25-day window after the August TRIM notice passes unnoticed. Buy this strategy every single tax cycle — there's no downside to filing if the comps support it.
LLC or trust titling for non-resident buyers — the wildcard. One spec that matters: titling doesn't reduce the tax bill at all, since non-homestead properties get no exemption regardless of entity structure, but it can simplify estate planning and privacy for international buyers. Consider it for privacy and succession reasons, not for tax savings — that expectation trips up a lot of foreign buyers in 2026.
Agricultural or Green Belt classification — the mismatch. One spec that matters: this reduces assessed value dramatically for working agricultural land, but Miami-Dade rarely approves it for waterfront estates or condos regardless of lot size. Skip it for any standard luxury residential purchase — it doesn't apply and pursuing it wastes the appeal window that should go toward a comps-based challenge instead.
What to avoid
- Assuming the developer's pre-sale price sets your tax basis. Preconstruction condos get reassessed at your actual purchase price and current market value once the certificate of occupancy issues, not the number from the original 2023 or 2024 sales brochure.
- Forgetting the non-ad valorem line items when budgeting. Buyers who only calculate millage rate times assessed value routinely underestimate the real bill by $2,000 to $5,000 because they miss drainage, seawall, or CDD assessments listed separately.
- Filing homestead late. Missing the March 1 deadline pushes the exemption — and the Save Our Homes cap — back a full year, which on a $4M property means paying an extra $15,000-plus in avoidable tax exposure for that year alone.

FAQ
What is the property tax rate on luxury homes in Miami?
Miami luxury home property taxes average close to 1% of market value in Miami-Dade County for 2026, with combined millage rates typically running 19 to 21 mills depending on the city and school district. The exact bill depends heavily on homestead status and any non-ad valorem assessments layered on top.
How much does the homestead exemption save in Miami-Dade?
The homestead exemption removes up to $50,000 from assessed value and, more valuably, activates the Save Our Homes 3% annual cap on assessed value growth. Over a decade of ownership in a rising market, that cap alone can save a luxury homeowner tens of thousands of dollars a year.
Do non-resident buyers pay higher property taxes in Florida?
Non-resident buyers pay tax on the full assessed value with no homestead exemption and no 3% cap, only the 10% non-homestead cap on annual assessment growth. This means a non-resident owner of a $4M Miami property will typically pay more over time than a homesteaded owner of the same home.
What is the Save Our Homes cap?
Save Our Homes limits annual assessed value growth to 3% or the Consumer Price Index, whichever is lower, but only for homesteaded primary residences. Non-homestead properties, including most investment condos, get a 10% cap instead.
Can you appeal a luxury home's tax assessment in Miami?
Yes, owners can file a Value Adjustment Board petition within roughly 25 days of receiving the August TRIM notice from Miami-Dade County. Successful appeals on over-assessed multimillion-dollar estates have reduced annual bills by $8,000 to $15,000 in documented cases.
Is portability worth it when buying a new luxury home?
Portability is worth pursuing if you've held a Florida homestead for several years and built up a large gap between assessed and market value, since up to $500,000 of that savings transfers to the new purchase. It has to be filed within two years of selling the prior homestead — it isn't automatic.
What are non-ad valorem assessments in Miami-Dade?
Non-ad valorem assessments are flat-dollar charges for things like drainage districts, seawall maintenance, or CDD infrastructure bonds, billed separately from the millage-based property tax. They can add $1,500 to $6,000 a year on waterfront or coastal luxury properties depending on the community.
How much are property taxes on a $5 million home in Miami?
At a combined millage rate near 20 mills with no exemptions, a $5M assessed property owes roughly $100,000 a year before any homestead reduction. A homesteaded owner with the Save Our Homes cap applied over several years of ownership typically pays meaningfully less than that figure.
One last thing
The number buyers overlook most in 2026 isn't the millage rate — it's the reassessment jump on preconstruction condos the first full year after closing, when the county replaces the developer's original pre-sale price with actual purchase price and current market value. A unit that felt like a bargain at 2023 pricing can show up with a tax bill calculated on 2026 market value, and that gap has caught more than one investor off guard at the November mailing.
