Boone County's 2026 property tax bills went out by the end of September. Each one bundles a stack of separate levies: county, schools, library, fire district, health and extension. This year, two of the biggest taxing bodies on that bill voted to lower their rates. Even so, plenty of bills came in higher than last year's.
Both things are true at once. The reason matters most if you're about to buy a house here, because the tax line on a Boone County listing reflects the seller's assessment history. It doesn't predict the bill you'll get.
The first bill you pay probably won't carry your name
Start with the part that surprises buyers at the closing table. The Boone County PVA's FAQ says that if you buy after January 1, you won't get a tax bill in your own name until the following year. Depending on your closing statement, you may end up paying the current bill issued in the previous owner's name, settled as a closing-cost adjustment.
The PVA puts the key detail plainly:
"Taxes will be based on the current years assessment value which may be different than your sales price."
So if you close on a Florence or Hebron house in spring 2027, the 2027 bill is still built on the January 1, 2027 assessment. What you paid for the house doesn't set it. Whether that assessment is close to your price, or well below it, depends on a cycle most buyers have never heard of.
Revaluation comes in four-year steps
The PVA values residential property as of January 1 each year. It uses a computer-assisted mass appraisal system that starts with a cost approach and adjusts it for each PVA neighborhood using valid arm's-length sales. The state requires assessments to land between 90% and 110% of market value in its annual ratio studies.
The PVA FAQ also says an individual property is "usually only revalued once every four years," and that when it is, "the increase reflects all four years worth of appreciation."
That's how one house's tax bill can lag the market and then catch up all at once. Take two similar houses on the same street. If one was revalued last year and the other is due next year, their bills can differ for reasons that have nothing to do with the houses. The first has already absorbed several years of appreciation. The second hasn't yet.
For a sense of how much appreciation has been building, the Northern Kentucky MLS reported a median sale price of $319,950 for August 2026, up 6.7% from $300,000 in August 2025. That figure covers the whole MLS area, not just Boone County. A home that goes several years between revaluations is carrying years of gains like that, waiting to show up on the bill.
HB 44 limits the rate. It doesn't touch the assessment.
House Bill 44 is the reason rates keep falling while bills don't. The PVA's FAQ describes it as a law limiting growth in countywide tax revenue to 4% a year, and calls it "a very complex formula that dictates only the tax rate, not the assessment value."
The Kentucky Department of Revenue lays out the menu every taxing district picks from:
- Compensating rate: the rate that brings in the same revenue as last year from property that was already on the rolls. New property is left out of the calculation.
- 4% rate: up to 4% more revenue from that existing base, plus whatever new property brings in. It requires a public hearing.
- Above 4%: requires a hearing and can be put to a recall vote.
When assessments rise, the rate that produces the same revenue goes down. A falling rate is the arithmetic side effect of rising values, not a cut in what the district collects. LINK nky's explanation adds that the state Department of Local Government certifies the tax roll and calculates both rates. A fiscal court that doesn't adopt a rate within 45 days of certification gets the compensating rate automatically.
What Boone County's two big levies did in 2026
| Taxing body | Prior real property rate | 2026 real property rate | What the new rate is designed to do |
|---|---|---|---|
| Boone County Fiscal Court | 8.5 cents per $100 | 8.2 cents per $100 | About $17.5M from real and tangible property, roughly $195,000 above budget |
| Boone County Schools | 65.5 cents per $100 | 64.6 cents per $100 | 4% more revenue than the prior year |
The Fiscal Court vote continued a long trend. County Administrator Matthew Webster told the court the real property rate has fallen every year since 2014, when it was 10.5 cents. He also reported that countywide assessments grew 6.58% to about $25.8 billion. Real property assessments rose 7.89% to nearly $20 billion, and the county added roughly $350 million in new property to its tax rolls.
The school levy takes up much more of the bill, and the math is easy to follow. LINK nky reported that on $100,000 of assessed value, the new rate works out to $646 in school tax, compared with $655 at the old rate. That saves $9 per $100,000, as long as the assessment stays the same. If a home's assessment rises by a bit under 1.4%, the savings are gone. A home that was revalued this year after four years of appreciation will see its bill go up, even at the lower rate.
Why the school board chose the 4% option
Coverage that LINK nky republished from WCPO laid out both sides of the decision. State Rep. Marianne Proctor told the meeting that Boone County property assessments had risen 21.9% and that owners would pay more "even though the rate may be a little bit lower." None of the coverage explains what time period or property group that 21.9% covers, so it can't be lined up against the county's reported 7.89% growth in real property assessments.
Board member Karen Byrd said in the same coverage that aiming only for last year's revenue could mean cutting 42 positions. State data provided to WCPO projected that Boone County could lose 2.7% of its state SEEK funding in 2027, while local property tax collections are projected to rise 7.5%. FOX19 reported that the board heard public comments both for and against before voting unanimously. FOX19 also put the 4% levy's revenue from new and personal property at just over $27 million.
The other levies on the bill, including the library, fire district, health and extension, set their own rates. Their 2026 decisions weren't in the coverage we reviewed. The county's rate page shows 2025 fire district real property rates ranging from 13.5 to 20 cents per $100. That range is one more reason two homes of similar value in different parts of the county can have different bills.
What a listing's tax figure tells you
Put it together and the "annual taxes" line on a Boone County listing is a snapshot of three things:
- The seller's assessment as of January 1, which may date from a revaluation one, two or three years back.
- The rates each taxing district adopted that year.
- The fire district and any other local levies tied to that address.
The sale price isn't one of them. The PVA does use valid sales to calibrate its neighborhood models, so sales shape assessments across a neighborhood over time. But nothing makes a house's assessment jump to its sale price the day it closes. If a home is due for revaluation soon after you buy it, the bill moves with that cycle, and that can happen whether this year's rate went up or down.
The 2026 payment calendar
The Boone County Sheriff's schedule for 2026 bills:
- Oct. 1 to Nov. 1, 2026: 2% discount
- Nov. 2 to Dec. 31, 2026: face amount
- Jan. 1 to Jan. 31, 2027: 5% penalty
- Feb. 1 to April 15, 2027: 10% penalty plus a 10% Sheriff add-on
- After close of business April 15, 2027: unpaid bills transfer to the County Clerk
As of today, about three weeks remain in the discount window. The Sheriff's office says bills are mailed by September 30 and asks anyone who hasn't received one to contact the office.
FAQ
Can I still appeal my 2026 assessment? The PVA mails notices by May 1 to owners whose assessment changed. For 2026, the deadline to finish the PVA conference step of an appeal was 4:30 p.m. on May 18. The PVA's FAQ says its office will meet with owners to go over the sales behind an assessment.
Why does a large acreage parcel nearby carry a lower value than my house? According to the PVA, land that usually exceeds 10 acres and is actively used for agriculture or horticulture can qualify for an agricultural value instead of full fair cash value.
Is the PVA part of county government? No. LINK nky notes that the PVA is an independently elected official who works under the Kentucky Department of Revenue, even though the office is in the Boone County Administration Building in Burlington.
Does this work the same way in Kenton County? The state rules are the same, but local rates and assessment timing differ. Our Kenton County property tax guide covers that side of the line, and our Union homestead exemption post explains one exemption available to qualifying owners.
