Property taxes are one of the most misunderstood costs of homeownership in Miami — and one of the most important to understand before you buy. With a background in finance and accounting, this is an area I walk every client through carefully, because the numbers can surprise you if you're not prepared.
How Miami-Dade Property Taxes Are Calculated
Property taxes in Miami-Dade are based on the assessed value of your property multiplied by the local millage rate. The millage rate varies by municipality — the City of Miami, Coral Gables, Pinecrest, Doral, and unincorporated Miami-Dade all have slightly different rates. As a general rule, expect total property taxes of roughly 1% to 2% of the assessed value annually. On a $500,000 home, that's $5,000 to $10,000 per year — or $417 to $833 per month added to your housing cost.
The Homestead Exemption — This Is Important
Florida offers a homestead exemption of up to $50,000 off the assessed value for your primary residence. If you're buying a home to live in (not an investment property), you can apply for this exemption and reduce your taxable value significantly. On a $500,000 home, a $50,000 exemption saves you roughly $1,000 to $1,500 per year depending on the millage rate.
But here's what many buyers miss: the homestead exemption also comes with the Save Our Homes cap, which limits how much your assessed value can increase each year — currently capped at 3% or the rate of inflation, whichever is lower. This is enormously valuable in a rising market like Miami, because your taxes won't spike even as home values climb.
The Reset Problem When You Buy
If you're buying a home from someone who has owned it for many years, their assessed value — and therefore their tax bill — may be far below what the property would be assessed at today. When the home sells, the Save Our Homes cap resets. The property is reassessed at or near the purchase price, and your first full year of taxes could be significantly higher than what the previous owner was paying. Always ask your agent or lender to estimate your actual post-purchase tax bill — don't use the seller's current tax bill as your baseline.
Investment Properties and Rentals
If you're buying an investment property or a second home, the homestead exemption doesn't apply and the Save Our Homes cap doesn't protect you either. Your assessed value can increase more freely with the market, and your tax exposure is higher.
How to Look Up a Property's Tax Information
The Miami-Dade Property Appraiser's website (miamidade.gov/pa) lets you look up any property's current assessed value, exemptions, and tax history. It's a valuable tool when evaluating a purchase — I use it on every deal I work on.
