Long-time Florida homeowners who locked in their homestead exemption years ago pay property taxes on assessed values that can be a fraction of what their homes would sell for today. The constitutional rule behind this protection, known as Save Our Homes, caps annual assessment increases at the lesser of 3 percent or the change in the consumer price index. For seniors who have held homestead status since the 1990s, the gap between their assessed value and actual market value can represent tens of thousands of dollars in shielded wealth, but that gap does not erase the local tax burden. It shifts it.
Why the 3 percent cap reshapes who pays what in Florida
The mechanism is straightforward but its consequences compound over time. Florida’s Constitution sets the annual cap on increases in assessed value for homestead property at the lesser of 3 percent or the CPI change. When home prices rise faster than that ceiling, and they have done so in much of Florida for years, the taxable value assigned to a long-time owner falls further and further behind the property’s just value.
That growing spread between assessed and market value means local governments still need to collect the same revenue. The difference gets distributed across properties that do not carry the same accumulated cap benefit, primarily homes purchased more recently. A buyer who closed on a house after 2015 starts with an assessed value at or near full market price and only then begins building cap savings of their own. Counties where a large share of homesteads date back to the late 1990s or early 2000s carry the widest cumulative divergence, and the tax load on newer buyers in those counties is proportionally heavier.
The hypothesis that this divergence will keep growing through 2027 and beyond rests on a simple math problem: as long as Florida home prices outpace 3 percent annual growth, the spread widens each year for every pre-existing homestead. No county-level dataset in the available public record quantifies the exact share of the tax burden that has shifted to post-2015 buyers, but the structural incentive is embedded in the constitutional text itself. The more volatile the housing market becomes, the more pronounced the relative advantage for those already protected by the cap compared with families trying to buy into the same neighborhoods today.
How Section 193.155 applies the cap after year one
The implementing law spells out when and how the cap takes effect. Section 193.155 of the Florida Statutes provides the mechanics of how homestead property is assessed, applying the capped increase after the first year of receiving homestead exemption. That means a new homeowner’s first assessment reflects the property’s just value at the time of purchase. Only in the second and subsequent years does the 3 percent ceiling kick in.
The statute also addresses triggers that reset the cap, such as changes in ownership. When a homesteaded property sells, the new owner’s assessed value resets to market value, and the cycle starts over. For a senior who has lived in the same home for two or three decades without selling, the accumulated savings under the cap can be enormous, because each year’s small increase compounds on an already-suppressed base rather than on the property’s actual worth.
This reset mechanism is what makes the system self-reinforcing for long-time owners. A senior who bought a home for $120,000 in 1997 and never sold it could have an assessed value far below a neighbor’s identical home that last changed hands in 2022 at a price several times higher. Both owners rely on the same local services, but the newer buyer shoulders a much larger property tax bill because their assessment started at current market value. Over time, these individual disparities add up to a structural pattern in which tenure, not just home size or location, becomes a key driver of who pays what.
Portability, policy debates, and who can change the rules
Florida has attempted to soften some of the sharpest edges of this system by allowing limited portability of Save Our Homes benefits when a resident moves, but the basic architecture remains: the longer a homeowner stays put, the more protection they accumulate, and the more the relative burden shifts toward newer entrants. This raises recurring policy questions about intergenerational equity, housing mobility, and whether the cap unintentionally discourages downsizing by seniors who fear losing their locked-in assessment.
Any significant change to the Save Our Homes framework would require action by state policymakers. Proposals to adjust the cap, expand portability, or recalibrate how assessments respond to market shocks would have to move through the legislative process in Tallahassee, beginning with committees and floor votes in bodies such as the Florida House. Because the cap is grounded in constitutional language, some reforms would also require voter approval of an amendment, adding another layer of political and practical complexity.
For now, the system continues to reward stability of ownership while gradually shifting more of the tax load to those who bought in after long years of price appreciation. As Florida’s population grows and housing markets remain tight, the disparities created by a 3 percent cap in a double-digit appreciation environment are likely to become more visible to taxpayers comparing bills with their neighbors. Whether that visibility translates into momentum for reform will depend on how voters balance the promise of protection for long-time residents against the mounting costs borne by the newcomers who share their streets and schools.
