When you compare Pinellas vs Pasco vs Hillsborough property taxes, Pinellas generally has the lowest total millage of the three, and Hillsborough has the highest. But millage is only half the story, and the other half is what actually surprises people.
The bigger factor is that your tax bill resets when you buy. The number the current owner pays is not the number you will pay.
This guide gives you the current millage rates, worked math on a real price point, and the two costs that vary far more than the county line does.
How a Florida Property Tax Bill Is Built
Your bill has two parts. Understanding the split makes everything else easier.
Part one is the ad valorem tax. This is millage multiplied by taxable value. One mill equals $1 per $1,000 of taxable value. Several taxing authorities each set their own millage, and they stack into one total.
Part two is non-ad valorem assessments. These are flat charges that have nothing to do with your home's value. Solid waste, stormwater, fire assessments, and community development district payments all land here.
That second part is where two homes with identical values can have very different bills. A CDD assessment alone can add $1,500 to $3,000 a year in newer communities.
What Are the Current Millage Rates?
Here are the current total millage rates across the three counties. These are the combined figures from all taxing authorities on a typical parcel.
Area | Total millage | Tax per $100,000 of taxable value |
|---|---|---|
Unincorporated Pinellas | 15.3229 | $1,532 |
Unincorporated Pasco | approx. 17.0 | approx. $1,700 |
Unincorporated Hillsborough | 17.9049 | $1,790 |
Plant City | 18.1619 | $1,816 |
Temple Terrace | 19.5012 | $1,950 |
City of Tampa | 19.7121 | $1,971 |
A note on the Pasco figure. Pasco County's own adopted aggregate millage for fiscal year 2026 is 10.1407 mills, which breaks down as 7.4042 for the general fund, 2.1225 for the municipal fire service unit, 0.4052 for roads, and small voted debt service levies. Other taxing authorities are added on top of that county figure, which puts most unincorporated Pasco parcels in the high-16 to 17 mill range.
Millage changes every year. Treat these as a planning baseline, then verify the exact number for a specific address on the county property appraiser's site or the TRIM notice.
Which County Actually Costs More?
Let's run the math on a $450,000 home with a homestead exemption in each county.
The standard homestead exemption is up to $50,000 off assessed value, though the second $25,000 does not apply to every levy. To keep this simple and conservative, we will use $400,000 in taxable value.
Area | Taxable value | Estimated annual tax | Estimated monthly |
|---|---|---|---|
Unincorporated Pinellas | $400,000 | $6,129 | $511 |
Unincorporated Pasco | $400,000 | approx. $6,800 | approx. $567 |
Unincorporated Hillsborough | $400,000 | $7,162 | $597 |
City of Tampa | $400,000 | $7,885 | $657 |
The spread between unincorporated Pinellas and the City of Tampa is about $1,756 a year, or roughly $146 a month. On a 30-year budget that is real money, but it is smaller than most buyers assume before they see the math.
Here is the more important point: the gap between two homes inside the same county is often larger than the gap between counties. A newer home with a CDD assessment can easily cost more per year than an older home one county over without one.
Why Is My Tax Bill Higher Than the Seller's?
Because the assessed value resets when the property sells. This catches more Tampa Bay buyers than any other line item.
Florida caps annual increases in assessed value at 3% or the change in the Consumer Price Index, whichever is lower, for homesteaded properties. That cap is called Save Our Homes, and it builds up over time.
A homeowner who bought in 2011 may have an assessed value far below today's market value. Their tax bill reflects fifteen years of capped increases. When you buy that home, the cap resets to your purchase price.
So the $3,100 annual bill on the listing may become $6,900 for you in year one. Neither number is wrong. They are just measuring two different owners.
Three rules that keep you out of trouble:
- Never budget from the seller's current tax bill.
- Estimate your year-one bill using your purchase price and the local millage.
- Ask your lender to escrow based on that estimate, not the current bill, so your payment does not jump after the first year.
The Costs That Are Identical in All Three Counties
Not everything changes at the county line. These transfer costs are the same across Pinellas, Pasco, and Hillsborough.
- Documentary stamp tax on the deed: $0.70 per $100 of the sale price. On a $450,000 sale, that is $3,150.
- Documentary stamp tax on the note: $0.35 per $100 of the loan amount.
- Intangible tax on the mortgage: $0.20 per $100 of the loan amount.
- Homestead exemption: up to $50,000, applied for through the county property appraiser, with a March 1 filing deadline.
- Save Our Homes cap: 3% or CPI, whichever is lower, on homesteaded properties.
- Portability: lets you move accumulated Save Our Homes savings, up to $500,000, to your next Florida homestead.
Portability is the one people forget. If you are moving from a long-held Pinellas home to a new one in Pasco, you may be able to carry a large chunk of your assessment savings with you. That can matter more than the millage difference between the two counties.
What About CDD and Special Assessments?
A community development district assessment is a separate annual charge that funds the infrastructure in a newer community. Roads, drainage, amenities, and common areas are built with bonds, and residents repay those bonds through their tax bill.
CDDs are most common in newer master-planned communities across Pasco and Hillsborough. This is a major reason a specific area's real effective tax rate can run well above its county average.
Odessa is a clear example. The Pasco County median effective rate sits around 1.35% of value, while Odessa's median effective rate runs closer to 1.60%, with a median annual bill near $7,682. The county millage did not change. The composition of the housing stock did.
When you compare two homes, ask three questions:
- Is there a CDD, and what is the annual amount?
- Is the CDD bond portion still being paid, and what year does it end?
- What is the operations and maintenance portion, which continues after the bond is retired?
A CDD is not automatically a negative. It usually pays for amenities and infrastructure you are choosing to have. It just needs to be in the monthly number before you fall in love with a house.
How to Estimate Your Real Monthly Number
Here is the sequence that produces an accurate figure rather than a guess.
- Take the purchase price you are considering. That will be close to your year-one assessed value.
- Subtract the homestead exemption if the home will be your primary residence.
- Multiply by the total millage for that exact address, then divide by 1,000.
- Add any non-ad valorem assessments: CDD, solid waste, stormwater, fire.
- Divide by 12 for the monthly escrow figure.
- Add insurance separately. It is its own number and it varies by far more than taxes do.
Do this for every home you seriously consider. Two houses at the same price in two different neighborhoods can differ by $200 a month once assessments are included. That is the size of a car payment, and it is entirely knowable before you write an offer.
Frequently Asked Questions
Which county has the lowest property taxes: Pinellas, Pasco, or Hillsborough?
Pinellas generally has the lowest total millage of the three, at about 15.32 mills in unincorporated areas, compared with roughly 17 mills in unincorporated Pasco and 17.90 mills in unincorporated Hillsborough. Actual bills still depend on assessed value and any special assessments.
Why did my property taxes go up so much after I bought the house?
The assessed value resets to your purchase price when the home sells. The prior owner may have had years of Save Our Homes protection capping their assessment at 3% growth, and that protection does not transfer to you.
How much is property tax on a $450,000 home in Tampa Bay?
With a homestead exemption, expect roughly $6,100 a year in unincorporated Pinellas, about $6,800 in unincorporated Pasco, about $7,160 in unincorporated Hillsborough, and about $7,900 inside the City of Tampa. Add any CDD or other assessments on top.
What is the homestead exemption and when do I file?
It removes up to $50,000 from your assessed value on a primary residence and starts the Save Our Homes cap. File with your county property appraiser by March 1 for the year you want it applied.
Can I transfer my tax savings to a new home in a different county?
Yes. Portability lets you move up to $500,000 of accumulated Save Our Homes savings to a new Florida homestead, including across county lines. You generally need to establish the new homestead within the allowed window, so plan the timing with your agent.
Does a CDD assessment ever go away?
The bond portion ends once the community's bonds are repaid, which is often 20 to 30 years from the community's start. The operations and maintenance portion continues, because it funds ongoing upkeep of the shared infrastructure.
Are property taxes negotiable at closing?
The bill itself is not, but taxes are prorated between the buyer and the seller at closing based on the number of days each party owns the property that year. You can also file a petition with the county value adjustment board if you believe your assessed value is too high.
