What Is the Save Our Homes Cap and Why It Matters

Why Your Neighbor in Nocatee Might Be Paying Far Less in Property Taxes Than You Think

You are sitting across from your neighbor at a community event in St. Johns County -- same subdivision, homes built the same year, roughly the same square footage. But when the conversation turns to property taxes, the numbers do not match. At all. Your neighbor bought seven years ago. You bought two years ago. Your assessed values are worlds apart, and there is a Florida law that explains exactly why -- one that quietly protects long-term homeowners and becomes one of the most powerful financial tools in the state once you understand how to use it.

The Foundation: Florida's Homestead Exemption

Before understanding the Save Our Homes cap, it helps to understand its foundation: the Florida homestead exemption. If you own a home in Florida and it is your primary residence, you are eligible to file for a homestead exemption, which reduces the taxable value of your property by $25,000 -- and an additional $25,000 off the value above $50,000 for most taxes (excluding school district taxes).

The homestead exemption is the base layer. You apply for it the year after you purchase your home, through your county property appraiser's office. The deadline is typically March 1. Once you have homestead status, you become eligible for the Save Our Homes cap -- which kicks in automatically the year after your initial homestead assessment.

New buyers in St. Johns, Duval, or Nassau County sometimes miss the March 1 deadline in their first year, which means waiting another full year for the protection to take effect. Getting this filing done promptly is one of the most financially impactful things a new Florida homeowner can do.

How the Save Our Homes Cap Works

Once your homestead exemption is in place, Florida's Save Our Homes amendment limits how much your home's assessed value can increase each year. The cap is 3% or the Consumer Price Index (CPI), whichever is lower. In years of low inflation, the cap is CPI. In years of higher inflation, it is capped at 3%.

Here is why this matters so dramatically. Imagine you purchased a home in Nocatee in 2018 for $400,000. Over the next six years, the Northeast Florida market appreciates significantly -- your home's market value climbs to $600,000 or more. Without the Save Our Homes cap, your assessed value would follow the market up, and your tax bill would climb proportionally.

With the cap, your assessed value can only increase by 3% per year from its starting point. After six years of 3% annual increases on a $400,000 base, your assessed value would be approximately $477,000 -- while the market value of the home might be $600,000 or higher. You are being taxed on $477,000, not $600,000. The difference in your annual tax bill can be thousands of dollars, year after year.

For long-term homeowners in St. Johns County -- one of the fastest-appreciating real estate markets in Florida -- this protection has been enormously valuable. The gap between market value and assessed value in some Nocatee and St. Johns County neighborhoods has grown to six figures. That gap is not money you spend -- it is money you keep.

The Portability Benefit -- Taking Your Savings With You

Here is where Save Our Homes becomes one of the most powerful relocation tools in the Florida real estate market. When you sell your Florida homestead and purchase a new Florida homestead, you are allowed to transfer, or "port," your accumulated SOH benefit to your new home. This is called SOH portability.

Portability does not mean your tax bill stays exactly the same. It means the difference between your old home's market value and its assessed value at the time of sale -- your SOH savings -- can be applied to reduce the assessed value of your new home, subject to certain limits.

This is enormously significant for within-Florida movers. If you are a Nocatee homeowner who bought in 2017 and has accumulated significant SOH savings -- and you are now ready to upgrade to a home in Ponte Vedra Beach -- portability allows you to bring that benefit with you. Your new home's assessed value starts lower than it otherwise would, which means your property tax bill is lower from day one.

For the move from St. Johns County to the Ponte Vedra Beach market -- where home prices are typically higher -- this can meaningfully offset the tax impact of the upgrade. Buyers who understand portability are in a fundamentally better financial position than those who do not.

Why This Matters Most for St. Johns and Nassau County Homeowners

St. Johns County has been one of the fastest-growing and most appreciating real estate markets in Florida over the past decade. That growth has been good for homeowners' equity -- and the Save Our Homes cap has protected those same homeowners from being taxed out of their homes as values climbed.

Homeowners who purchased in Nocatee, Julington Creek Plantation, or Ponte Vedra Beach five or more years ago have often accumulated very significant SOH savings. The gap between their assessed value and their market value represents a real financial benefit that is worth understanding before making any real estate decision.

Nassau County, home to Fernandina Beach and Amelia Island, has seen similar appreciation patterns. Long-term homeowners there carry the same kind of SOH protection -- and the same portability opportunity when they are ready to move.

How to File for Portability -- The Process and Deadlines

Portability does not happen automatically. You must actively apply for it when you purchase your new Florida homestead. Here is how the process works:

First, you establish homestead on your new property and file your homestead exemption application by March 1 of the year following your purchase. At the same time, you file a portability application -- typically Form DR-501T in Florida -- which requests the transfer of your SOH benefit from your previous homestead to your new one.

The deadline for portability applications is the same as homestead: March 1 of the year following your purchase. You have up to two years from the date you abandoned your previous homestead to apply -- but the sooner you file, the sooner your protection is in place.

One important nuance: if you are moving to a less expensive home, your portability benefit is capped at the assessed-to-market difference on the new property. If you are moving up in price, you may be able to port the full difference. Your county property appraiser's office will calculate the exact benefit for your specific situation, and this calculation is worth reviewing before you close on your new home.

What This Means for Out-of-State Buyers

If you are moving to Florida from another state, Save Our Homes does not apply to your previous home -- portability only transfers SOH savings from a prior Florida homestead. But you immediately become eligible for the cap once you establish your first Florida homestead and your exemption is in place.

For out-of-state buyers, the message is simpler: file your homestead exemption promptly after closing, do not miss the March 1 deadline, and know that the SOH protection begins building from your very first year. The longer you own your Florida home, the more valuable this protection becomes.

This is one of the reasons that long-term Florida homeownership -- not just the lifestyle, but the financial structure of it -- tends to reward staying. The SOH benefit compounds over time, and homeowners who understand this often factor it into their decision about when and whether to move.

Frequently Asked Questions

What is the maximum SOH benefit I can port to a new Florida home?

The maximum portable SOH benefit is $500,000 -- the difference between the assessed value and the just (market) value of your previous homestead, capped at $500,000. In practice, very few homeowners reach this cap, but it is worth knowing the ceiling exists. Your county property appraiser can calculate your specific portable benefit.

Do I lose my SOH benefit if I move out of Florida and then come back?

Yes. If you sell your Florida homestead and establish a primary residence outside of Florida, you lose your accumulated SOH benefit. Portability only applies when you are moving from one Florida homestead to another. If you move away and later return to purchase a new Florida home, you start the SOH clock from zero.

What is the deadline to file for portability in Florida?

The portability application deadline is March 1 of the year following your new home purchase -- the same deadline as the homestead exemption itself. You also have a two-year window from when you abandoned your prior homestead to apply. Missing this deadline means losing the ability to port your SOH savings, so it is worth setting a calendar reminder well in advance.

If I upgrade from a home in Nocatee to a more expensive home in Ponte Vedra Beach, how does portability work?

You can port your full accumulated SOH difference to the new, more expensive property. The new home's assessed value will be reduced by the amount of your portable SOH savings, resulting in a lower starting assessed value -- and a lower tax bill -- than if you had purchased the Ponte Vedra Beach home without any prior Florida homestead history. The specific numbers depend on the assessed values at the time of each transaction, and your county appraiser will calculate the exact benefit.

Where do I file for the homestead exemption and portability in St. Johns County?

In St. Johns County, you file through the St. Johns County Property Appraiser's office. Applications can typically be submitted in person, by mail, or online through the property appraiser's website. The deadline is March 1 of the year following your purchase. For Nassau County properties, the Nassau County Property Appraiser's office handles the same process.
