Are Martin County Property Taxes Lower Than Palm Beach County?
It comes up in almost every conversation we have with buyers shopping between Jupiter and Stuart: are property taxes actually lower on the Martin County side? The short answer is yes, generally. The longer answer is more useful, because the county line runs right through some of the most interesting neighborhoods in our market, and understanding how the tax math works can meaningfully change where you shop.
Quick answer:
Martin County's effective property tax rate runs roughly 0.8 percent of home value, among the lowest in South Florida.
Palm Beach County's runs closer to 0.9 percent, depending on the municipality.
On an $800,000 home, that difference can amount to several hundred to over a thousand dollars a year, and it compounds every year you own.
Exact rates vary by city, school district, and special assessments, so two homes a mile apart can carry different bills.

Your bill is built from millage rates. One mill equals one dollar of tax for every $1,000 of taxable value, and your total millage stacks up from several layers: the county, your city or town, the school district, and special districts for things like fire rescue and water management. That is why "Martin versus Palm Beach" is a starting point, not the whole answer. The county sets one layer, but your specific address determines the full stack.
Each August, every Florida property owner receives a TRIM notice (Truth in Millage) showing the proposed rates and your property's assessed value for the year. It is not a bill, but it is the preview of one, and if you believe the assessment is too high, the appeal window is short: 25 days from the mailing date.
Because around here, the line does not separate two different lifestyles. It runs through one.
Tequesta sits at the seam. Communities like Turtle Creek carry a Tequesta identity and a Jupiter-area lifestyle while sitting on the Martin County side of the line, which is one of the quiet reasons buyers who do their homework end up there. Hobe Sound, Stuart, and Palm City are fully Martin County, with the beaches, the river, and the boating access that draw people to this stretch of coast in the first place.
The practical takeaway: if your search spans Jupiter to Stuart, you are comparing homes across two tax jurisdictions whether you realize it or not. Two similar homes at similar prices can carry noticeably different annual carrying costs based on nothing but which side of the line they sit on.
Three Florida rules shape what you actually pay, in either county:
Homestead exemption. If the home is your permanent residence, you can exempt up to $50,000 of assessed value ($25,000 of it applies to school taxes too). You need to own and occupy by January 1 and file by March 1 for that tax year.
Save Our Homes cap. Once homesteaded, your assessed value cannot rise more than 3 percent a year, no matter what the market does. Long-term owners often pay taxes on assessed values far below market value.
Portability. If you are moving within Florida, you can transfer up to $500,000 of that accumulated Save Our Homes benefit to your next home. For longtime Florida homeowners moving up the coast, this is real money, and it works across county lines.
This is the mistake we see most. A buyer pulls up a listing, sees the seller paid $6,000 last year, and budgets accordingly. But the Save Our Homes cap resets at sale. The property is reassessed at market value for the new owner, which means your first full-year tax bill can be substantially higher than the number on the listing, especially if the seller owned for a decade or more.
The right way to budget: estimate from the purchase price and the local millage, not from the seller's history. It is a five-minute calculation that prevents a very unwelcome November surprise, and it is one we run for our buyers on every offer.
Yes, Martin County generally taxes lighter than Palm Beach County, and along the Tequesta and Hobe Sound corridor, that difference comes without giving up the coastal lifestyle that brought you here. But the county is only the first layer. The municipality, the exemptions you qualify for, and the reset that happens at sale all shape your real number. When your TRIM notice lands in August, or when you are comparing homes on opposite sides of the line, the math is worth doing precisely.
