What is the Ohio property tax assessment ratio?

Ohio law sets taxable value at 35% of market (true) value statewide, under Ohio Revised Code §5713.03. Your county auditor must use this ratio when calculating your tax bill.

How much is the Ohio Homestead Reduction in 2026?

For tax year 2026, the general Homestead Reduction shields $29,000 of market value for qualifying owners age 65+, totally disabled, or surviving spouses age 59+ with Ohio Adjusted Gross Income under $41,000. The enhanced amount for 100% disabled veterans and surviving spouses of public-safety officers killed in the line of duty is $58,000 with no income limit. File DTE Form 105A with your county auditor.

When is the Ohio Board of Revision deadline?

Ohio's statutory Board of Revision (BOR) complaint deadline is March 31 for the prior tax year, per ORC §5715.19. Complaints are filed using DTE Form 1 with your county auditor at no cost. Late filings are rejected except in very narrow clerical-error circumstances.

How much is the Ohio real property conveyance fee?

Ohio's conveyance fee has two parts: a mandatory $1.00 per $1,000 state fee (ORC §319.54(F)(3)) and a permissive county levy of up to $3.00 per $1,000 (ORC §322.02). Most Ohio counties charge the full $4.00 per $1,000. A separate $0.50 transfer fee applies per parcel. Filed using DTE Form 100 at the auditor's office at closing.

Who qualifies for Ohio's CAUV agricultural tax break?

Ohio's Current Agricultural Use Value (CAUV) program lets actively farmed land be taxed on its agricultural value rather than its market value. Eligibility requires 10+ acres devoted exclusively to commercial agriculture, or smaller parcels with $2,500+ in gross annual income from agriculture. Apply using DTE Form 109 and renew annually with DTE 109A. Removing land from CAUV triggers recoupment of three years of saved taxes under ORC §5713.34.

Hillsborough County Auditor FL: Property Search & Records

Hillsborough County, Florida · Parcel search, values, taxes, deeds, maps and exemptions

Find the Right Hillsborough Property Record

Searching for a “Hillsborough County Auditor” can send Florida property owners to the wrong office because Hillsborough County does not use an Ohio-style Auditor property system. The elected Property Appraiser maintains parcel ownership, values, exemptions and property-record information.

This guide connects that search with the complete Florida workflow: find a property by folio, parcel number, owner or address; understand market, assessed and taxable values; review GIS and flood or zoning context; check tax bills; locate recorded deeds; and act before Homestead or Value Adjustment Board deadlines.

Florida office-name warning: If another website tells you to contact the “Hillsborough County Auditor” for a Florida property appraisal, that is misleading terminology. Use the Property Appraiser for property value and parcel records, the Tax Collector for tax payments, and the Clerk for recorded deeds and liens.

Quick answer: start with the Property Appraiser

Use the official Hillsborough County Property Appraiser search to look up a parcel by folio, parcel number, owner or address. Once you find the record, copy the folio and parcel number because those identifiers make the tax, GIS, deed, exemption and appeal steps much easier.

Understand market, assessed and taxable value

Important Hillsborough County property fields
Field	What it means	Why it matters
Folio	HCPA property-record identifier.	Useful across searches, forms and county research.
Parcel Number	Legal parcel identification structure.	Useful for land and official-record matching.
Owner	Ownership currently displayed by HCPA.	Use the Clerk’s deed when legal title proof is required.
Market / Just Value	Property Appraiser’s estimate of fair market or just value as of January 1.	This is the main value to review for an appraisal dispute.
Assessed Value	Value after applicable assessment limitations.	May be lower than market value because of Save Our Homes or other limitations.
Taxable Value	Value after applicable exemptions.	Taxing authorities generally apply millage to taxable value.
Sales History	Recorded property-transfer activity associated with the parcel.	Useful for valuation research, but review the actual deed for legal details.
Land / Building Details	Characteristics used to describe and appraise the property.	Incorrect square footage, condition or land data can affect valuation research.
Exemptions	Homestead or other approved tax exemptions.	These can reduce taxable value.

Common mistake: Market value and taxable value are not the same figure. A Homestead property can have a market value substantially above its assessed value because of the Save Our Homes limitation.

2025 taxes and 2026 property values are different timelines

As of August 7, 2026, the key distinction is that 2025 property-tax bills were due by March 31, 2026, while the 2026 property assessment cycle is moving toward August TRIM notices and the tax bills that become payable later in 2026.

TRIM notice: review your value before the appeal deadline

Hillsborough County Property Appraiser mails Truth in Millage notices in August. The notice shows the proposed property-tax picture and the Property Appraiser’s January 1 value.

Deadline warning: owners generally have only 25 days from the mailing date of the TRIM notice to file a value petition with the Value Adjustment Board. Do not calculate the deadline from the day you opened the envelope.

Review the TRIM notice in this order

Confirm owner and property Verify folio, physical address and property description.

Review market / just value Ask whether the January 1 value reasonably reflects the property’s market.

Review assessed value Check whether Save Our Homes or another assessment limitation appears as expected.

Review exemptions Confirm Homestead, disability, veteran, widow/widower or other approved exemptions.

Review proposed millage Remember that taxing authorities—not HCPA—set the tax rates.

Write down the VAB filing deadline The exact deadline should appear on the notice.

Start informally first: HCPA encourages property owners who disagree with the assessment to contact the Property Appraiser for a value review before or while considering a formal VAB petition.

Homestead and personal exemptions

Normal March 1 deadline passed—but check late filing

The statutory filing deadline for Hillsborough County real-estate exemptions is March 1. HCPA accepts applications year-round, but the tax-year deadline rules determine whether an application can still apply to the current year.

August 2026 late-filing opportunity: HCPA states that late-filed exemption applications may be accepted through the 25th day after the annual TRIM notice is mailed. After that statutory period expires, Florida law does not allow the Property Appraiser to accept the application for that calendar year.

Why your assessed value may be below market value

Florida’s Save Our Homes limitation applies to qualifying Homestead property. After the property first receives Homestead, annual increases in assessed value are generally limited to the lesser of 3% or the applicable Consumer Price Index change, subject to statutory exceptions.

Market / Just Value

What HCPA estimates the property is worth in the market as of January 1.

Assessed Value

May reflect the Save Our Homes assessment limitation.

Taxable Value

Assessed value after applicable exemptions are subtracted.

Buyer warning: A seller’s low assessed value does not automatically transfer to a buyer. HCPA explains that after a change of ownership, the property is generally raised to full market value on January 1 of the following year before the new owner’s applicable Homestead and assessment limitation take effect.

Portability may preserve part of the assessment benefit

Florida portability can allow an eligible Homestead owner to transfer qualifying Save Our Homes assessment benefit to another Florida Homestead. HCPA’s portability material lists a maximum portability transfer of $500,000 and explains that statutory time limits apply.

Form connection: HCPA lists DR-501T as the Transfer of Homestead Assessment Difference form, and it must be submitted with the Homestead application when applicable.

Read Save Our Homes guidance Open portability forms

Agricultural classification

Greenbelt filing and agricultural property records

Hillsborough County Property Appraiser administers Florida agricultural classification. The application is DR-482 and must normally be filed on or before March 1 of the current tax year.

Application asks about actual agricultural use

Folio number

Legal description

Agricultural acreage

How long the land has been used agriculturally

Citrus or crop use

Grazing and livestock

Timber use

Agricultural income and expense evidence

Do not confuse agricultural appearance with agricultural classification. Owning acreage, keeping a few animals or having vacant rural land does not automatically establish a qualifying bona fide agricultural use.

If an agricultural classification application is denied, HCPA states that the owner generally has 30 days from the mailing of the denial notice to petition the Value Adjustment Board.

Common mistakes

Avoid these Hillsborough property-record dead ends

Searching for a Florida “County Auditor” office Use HCPA, Tax Collector or Clerk based on the actual task.

Using assessed value as market value Save Our Homes can create a substantial difference between the two.

Paying tax through the Property Appraiser Property taxes are collected by Nancy Millan’s Tax Collector office.

Using owner display as legal title proof Search the recorded deed through the Clerk.

Using GIS lines for a fence HCPA maps do not constitute legal surveys.

Missing the VAB deadline while negotiating informally A discussion with HCPA does not automatically extend the statutory petition deadline.

Assuming March 1 means Homestead is impossible Check whether the statutory late-filing period after TRIM mailing is still open.

Assuming seller’s low tax bill will continue A change of ownership can reset assessed value before the buyer’s new Homestead limitation applies.

Ten practical answers

Hillsborough County property-search FAQs

Does Hillsborough County Florida have a County Auditor property search?

Florida does not use an Ohio-style county auditor for property appraisal. In Hillsborough County, the elected Property Appraiser handles parcel ownership, values and exemptions; the Tax Collector handles property tax billing and payment; and the Clerk of Court and Comptroller maintains deeds and other official records.

Who is the Hillsborough County Property Appraiser?

Bob Henriquez is the Hillsborough County Property Appraiser. His office appraises real estate and tangible personal property and maintains the county property-search system.

How can I search Hillsborough County property records?

Use the Hillsborough County Property Appraiser search. You can search using a folio number, parcel number, owner name or property address.

What is a Hillsborough County folio number?

A folio is an identifier used by the Hillsborough County Property Appraiser for property records. It is useful for exact parcel searches, exemptions, tax research, maps and county forms.

Where do I search Hillsborough County deeds and mortgages?

Search the Hillsborough County Clerk of Court and Comptroller’s Official Records. The Clerk maintains deeds, mortgages, liens, plats, notices of commencement and other recorded documents.

When are Hillsborough County property taxes due?

Property taxes become payable November 1 and are due in full by March 31 of the following year. Unpaid real-estate taxes become delinquent April 1.

Can I still file for Homestead Exemption after March 1?

The normal statutory filing deadline is March 1. Hillsborough County Property Appraiser accepts certain late-filed applications through the 25th day after the annual TRIM notice is mailed. After that statutory late-filing period, the Property Appraiser cannot accept an application for that tax year.

How long do I have to appeal my Hillsborough County property value?

Property owners generally have 25 days from the mailing date of the TRIM notice to file a value petition with the Hillsborough County Value Adjustment Board. The exact deadline appears on the TRIM notice.

Are Hillsborough County parcel maps legal surveys?

No. The Property Appraiser states that its maps do not constitute legal surveys and should not be relied upon in place of a title search or survey to determine ownership or exact property boundaries.

What is the Hillsborough County Property Appraiser phone number?

The Hillsborough County Property Appraiser can be reached at 813-272-6100. The downtown office is at 601 East Kennedy Boulevard, 15th Floor, Tampa, Florida 33602-4932.

Verify with the official Ohio source

These calculators use the verified 2026 Ohio Department of Taxation amounts and statutory rules. For your exact bill, exemption status, and county-specific deadlines, always confirm with your county auditor and the Ohio Revised Code:

Ohio Dept. of Taxation — Real Property DTE Forms (105A, 105C, 1, 109) ORC 5715 — Board of Revision ORC 5713 — Taxable Real Property ORC 322.02 — Conveyance Fee ORC 319.54(F)(3) — State Fee ORC 5713.30 — CAUV tax.ohio.gov — Main Portal

Estimates use Ohio's 35% statutory assessment ratio and effective tax rate tiers averaged across major Ohio counties. Your actual bill depends on local school levies, voted millage, inside vs. outside millage splits, House Bill 920 reduction factors (HB 920), and special assessments. The 2026 Homestead general amount ($29,000) and enhanced amount ($58,000) reflect HB 187 inflation indexing — your county auditor's office may show slightly different transitional figures.
