Property Taxes on Luxury Homes in Palm Beach (2026 Guide)
Luxury property taxes in Palm Beach County run on rules most buyers never touch until they close — Save Our Homes caps, non-homestead assessment jumps, and a TRIM notice that can swing a six-figure home's tax bill by thousands. This guide walks through exactly how the math works and what to do at each step so nothing surprises you after the closing table.
- Palm Beach County combined millage typically lands between 18 and 22 mills, so a $4M waterfront estate can owe $70,000-$90,000 a year.
- Save Our Homes caps annual assessment growth at 3% for homesteaded owners, but a new purchase resets the assessed value to market price.
- Non-homestead properties, including most investment condos, cap increases at 10% annually under Florida law.
- TRIM notices arrive every August — the 25-day appeal window closes fast, so calendar it the day you get it.
- Portability lets a seller carry up to $500,000 of Save Our Homes savings into a new Florida homestead.
Why this matters
A luxury home in Palm Beach doesn't get taxed like a starter condo in West Palm Beach's inland neighborhoods. Waterfront and oceanfront parcels carry higher assessed values, and the property tax bill on a $6M estate can run $100,000 or more a year once the Save Our Homes cap resets at sale.
Buyers who skip this math get blindsided at the first TRIM notice, sometimes twelve months after closing when the county reassesses to full market value. Sellers who understand portability, on the other hand, can carry meaningful savings into their next Florida purchase instead of losing them.
What you'll need
- The property's most recent tax bill or TRIM notice from the Palm Beach County Property Appraiser
- The parcel's folio number to pull assessment history online
- A homestead exemption application if the home will be a primary residence
- Documentation for portability if you're selling a homesteaded Florida property and buying another
- A closing statement showing purchase price, since it becomes the new assessed value baseline
- Contact information for a tax attorney or CPA if the property involves an LLC, trust, or foreign ownership structure
The steps
1. Pull the current assessed value, not the market value
The seller's tax bill reflects the assessed value under the previous owner, which is almost never what you'll pay. Florida law resets the assessed value to the purchase price (or appraised market value) in the year following a sale.
Check the Palm Beach County Property Appraiser's site for the folio's assessment history before you make an offer. Expected outcome: you'll see the gap between the seller's current bill and what your bill will actually be — sometimes double or triple.
Common mistake: buyers budget off the seller's tax bill and get hit with a much higher number in year two.
2. Calculate the millage rate for the exact parcel
Millage rates vary by taxing district — county, school board, municipality, and special districts like fire-rescue or water management all stack. Combined Palm Beach County millage typically falls between 18 and 22 mills depending on the municipality and whether the parcel sits in an incorporated town like Palm Beach itself.
Multiply the assessed value by the millage rate, divide by 1,000, and you get the annual bill before exemptions. Common mistake: assuming every Palm Beach zip code carries the same rate — they don't, and unincorporated areas often run lower than incorporated towns.
3. Apply the homestead exemption if it's your primary residence
Florida's homestead exemption removes up to $50,000 from assessed value for qualifying primary residences — $25,000 off all levies and an additional $25,000 off non-school levies for assessed values above $50,000. File by March 1 of the year following purchase.
This step also triggers the Save Our Homes cap, which limits future assessed value growth to 3% a year or the Consumer Price Index, whichever is lower. Expected outcome: predictable annual increases instead of full market swings.
4. Check whether the property qualifies for non-homestead treatment
Investment condos, second homes, and properties held in an LLC don't get the homestead exemption, but Florida still caps their annual assessment increase at 10% under a 2008 constitutional amendment. That's a real ceiling — it just resets differently than Save Our Homes.
For buyers running a 1031 exchange in Palm Beach, factor this 10% cap into your hold-period projections, since deferred gains can compound alongside rising assessments.
5. Use portability if you're selling a Florida homestead
If you're selling a homesteaded property in Florida and buying another within two years, you can transfer up to $500,000 of accumulated Save Our Homes savings to the new home. File Form DR-501T with your new homestead application.
Common mistake: waiting past the two-year window and losing the savings entirely — portability isn't automatic and has a hard deadline.
6. Read the TRIM notice the day it arrives
The Truth in Millage (TRIM) notice mails every August and shows the proposed assessed value, exemptions, and proposed millage rates from every taxing authority. It is not a bill — it's your opportunity to object before rates are finalized.
You have 25 days from the notice date to file a petition with the Value Adjustment Board if the assessed value looks wrong. Expected outcome: either confirmation the assessment is fair, or a corrected value before the November tax bill goes out.
7. Compare against similar markets before you commit
Before finalizing a purchase, run the same math against comparable luxury markets. Property taxes on luxury homes in Fort Lauderdale and property taxes on luxury homes in Miami carry different millage structures, and the delta matters when you're weighing waterfront inventory across South Florida in 2026.

Troubleshooting
- Your first-year bill is far higher than the seller's. This is the assessed-value reset, not an error. Recalculate using the purchase price, not the seller's old assessed value.
- You missed the March 1 homestead filing deadline. You can still apply for the following tax year, but you'll pay a full year without the exemption or the Save Our Homes cap.
- The TRIM notice shows a value you disagree with. File a Value Adjustment Board petition within the 25-day window — after that, the assessed value stands for the year.
- Portability didn't transfer as expected. Confirm Form DR-501T was filed with the new homestead application and that the sale-to-purchase window fell within two years.
- A property held in an LLC or trust got denied homestead status. Non-natural-person ownership structures generally don't qualify — this is common with foreign buyers and 1031 exchange holdings.
- Non-ad valorem assessments (fire, water district fees) are inflating the total bill. These sit outside the millage calculation and aren't capped by Save Our Homes or the 10% non-homestead limit.
Tools and resources
- Palm Beach County Property Appraiser's online folio search for assessment history
- The Value Adjustment Board petition form for contesting a TRIM notice
- Form DR-501T for portability transfers
- A closing attorney or CPA familiar with Florida ad valorem tax law, especially for LLC or foreign-buyer structures
- Comparable listings in waterfront homes for sale in Palm Beach to benchmark assessed values against active inventory

FAQ
How much are property taxes on a luxury home in Palm Beach in 2026?
A luxury home in Palm Beach typically owes 1.8% to 2.2% of assessed value annually once combined millage is applied, so a $5M estate runs roughly $90,000 to $110,000 a year. Exact amounts depend on the municipality and whether homestead exemptions apply.
What is Save Our Homes and does it apply to a new purchase?
Save Our Homes caps annual assessment growth at 3% for homesteaded properties, but it resets to full market value the year after a sale. New buyers pay based on purchase price before the cap starts protecting them going forward.
How much does the homestead exemption save on a luxury property?
The standard homestead exemption removes up to $50,000 from assessed value, split between school and non-school levies. On a multimillion-dollar property this is a small percentage, but it also unlocks the 3% Save Our Homes cap, which matters more over time.
When do TRIM notices arrive and what should I do with mine?
TRIM notices mail every August and show proposed assessed values and millage rates from each taxing authority. You have 25 days from the notice date to file a Value Adjustment Board petition if the number looks wrong.
Can I appeal my property tax assessment in Palm Beach County?
Yes, through a Value Adjustment Board petition filed within 25 days of your TRIM notice. Miss that window and the assessed value stands for the entire tax year.
Is there a cap on non-homestead property tax increases?
Non-homestead properties, including most investment condos and LLC-held homes, are capped at a 10% annual assessment increase under Florida's constitutional amendment. This is separate from the 3% Save Our Homes cap for homesteaded owners.
Do foreign buyers pay different property taxes in Florida?
Foreign buyers pay the same millage rates as U.S. citizens, but they generally cannot claim the homestead exemption since the property isn't their primary U.S. residence. This means no Save Our Homes cap and full exposure to the 10% non-homestead increase limit.
How does portability work when moving within Palm Beach County?
Portability lets a seller transfer up to $500,000 of accumulated Save Our Homes savings to a new Florida homestead, provided the purchase happens within two years of the sale. File Form DR-501T with the new homestead application to claim it.
One last thing
The biggest tax mistake in Palm Beach luxury real estate isn't the millage rate — it's forgetting that Save Our Homes resets on every sale. A seller who's owned a waterfront estate for 15 years might show a tax bill a fraction of what the same home will cost the next owner in 2026, and that gap alone has killed deals at the financing stage. Model the post-sale number before you write the offer, not after you close.
