What You Need to Know About Property Taxes When Buying a Home in Miami in 2025

When you're buying a home in Miami, it's easy to get caught up in the excitement of choosing neighborhoods, touring homes, and planning your move. But one key factor that often surprises buyers is property taxes.

Understanding how property taxes work in Miami-Dade County can help you avoid surprises and plan your budget more accurately. Whether you’re a first-time buyer or relocating within South Florida, this guide will help you make informed decisions and avoid costly mistakes.

💰 How Property Taxes Are Calculated in Miami

In Miami-Dade County, property taxes are based on the assessed value of the property, which is determined annually by the county property appraiser. The assessed value is not necessarily the same as your purchase price, but it often resets close to that figure after a sale.

The assessed value is then multiplied by the millage rate to determine your total property tax bill. The millage rate is set by multiple taxing authorities, including the city, county, school board, and other public services.

Florida residents may also benefit from several tax-saving programs, such as:

• Homestead Exemption: Reduces the taxable value of your primary residence by up to $50,000.

• Save Our Homes Cap: Limits the annual increase in assessed value to 3% for homesteaded properties.

• Portability: Allows homeowners to transfer their tax savings from a previous homestead to a new one within the state.

These programs can significantly reduce your long-term property tax liability and are vital to understand when planning your purchase.

📊 Property Tax Rates in 2025

As of 2025, the average property tax rate in Miami-Dade County is approximately 2.03% of a home's assessed value. That means:

• A home assessed at $400,000 would incur about $8,120/year in property taxes.

• A home assessed at $600,000 could result in a tax bill around $12,180/year.

However, if you qualify for the homestead exemption, your tax bill could be reduced significantly. For example, on a $400,000 home, you may only be taxed on $350,000 after exemptions are applied.

🤔 Things to Consider When Budgeting

Here are a few things buyers often overlook:

• New Construction vs. Resale Homes: New homes typically have no prior exemptions and a higher initial assessed value, which can lead to a larger first-year tax bill.

• Capped Increases Don’t Apply Right Away: The 3% assessment cap under Save Our Homes applies only after your first year with homestead exemption.

• Escrow Accounts: Most lenders collect your property taxes monthly and hold them in an escrow account, which is included in your mortgage payment.

• Tax Estimates Can Be Misleading: Sellers’ current taxes are based on their assessed value, which may be much lower than your future tax obligation. Always estimate based on the expected assessed value post-sale.

🚫 Don’t Get Caught Off Guard

One of the most common surprises for buyers is seeing their first tax bill jump far above what the seller was paying. This happens because once the property changes hands, the county resets the assessed value based on the new purchase price.

To avoid this:

• Ask your Realtor for an updated tax estimate based on the current year’s millage rate and your projected purchase price.

• Use the Miami-Dade Property Appraiser’s Estimator Tool to calculate a realistic tax projection.

• Don’t rely on the taxes listed on the MLS or seller disclosures alone.

Being informed from the beginning will help you budget accurately and avoid financial stress.
