Jurisdiction check: this page covers Boone County, Indiana, including Lebanon, Zionsville, Whitestown, Jamestown, Thorntown and Advance-area properties. Boone counties in Missouri, Kentucky, Iowa, Illinois and other states use different portals.

Which Boone County Office Handles Your Task?

The offices share property information but perform different legal functions. Moving to the correct office prevents payment, deduction and appeal mistakes.

Assessment, property card or appeal

The Assessor handles land and structure assessments, annual trending, Form 11 notices, property characteristics, sales disclosures, reassessment and local appeals.

Official Boone County Assessor Open Assessor Office

Tax statement, payment or delinquency

The Treasurer handles property-tax statements, payment processing, receipts, partial payments, delinquent balances and tax-sale payment questions.

Official Boone County Treasurer Review Tax Payments

Homestead, veteran or other deduction

The Auditor handles deductions, tax-cap allocations, ownership accounts, mailing-address forms and parts of the property-tax calculation.

Official Boone County Auditor Open Auditor Office

Deed, mortgage, lien or release

The Recorder maintains recorded real-estate instruments. The owner shown on a property card does not replace a recorded deed or title search.

Official Boone County Recorder Search Recorded Documents

Office split: the Assessor does not set tax rates, collect taxes or approve homestead deductions. Assessment, billing, deductions and deed recording are separate county functions.

How to Search Boone County Property Records

The official GIS is the best first stop for a home, condominium, commercial building, farm, vacant parcel or mobile-home account.

Open the official GIS

Use the county-linked GIS instead of a private property-report or people-search website.

Choose your strongest search field

Use parcel ID or state ID for an exact match. Address is normally easiest for a homeowner. Owner search helps when the location is unknown.

Enter fewer words first

Start with the house number and street name. For an owner, begin with the surname or a distinctive business or trust keyword.

Force the intended search type

Add an exclamation mark before an address or a forward slash before an owner name when the system interprets the entry incorrectly.

Confirm the correct parcel

Match the owner, address, parcel ID, state ID, legal description, property class and map location.

Open and save the property card

Review land, structures, assessment history, characteristics and sales information. Save the parcel number for later tasks.

Official Boone County GIS Open Boone County GIS

Use the Boone County GIS Search Syntax Correctly

The county GIS includes search shortcuts that are especially useful when a street name resembles an owner name.

Search goal	What to enter	Example or fix
Force an address search	Place an exclamation mark before the address.	!123 Main
Force an owner search	Place a forward slash before the owner name.	/Smith
Search a business or trust	Use the most distinctive part of the entity name.	Remove LLC, Inc., punctuation and unnecessary words.
Search a rural address	Start with the number and road name.	Remove the direction, road type, city and ZIP code.
Search vacant land	Use owner, parcel ID or a nearby address.	Open the map and select the parcel visually.
Find a subdivision or cemetery	Use the subdivision or cemetery search available in GIS.	Confirm the parcel rather than relying only on the subdivision name.

No-result checklist: remove the unit number, punctuation, city, ZIP code, directional prefix and street suffix. Then try the parcel ID, state ID or map.

What the Boone County Property Card Shows

The property card explains the assessment record. It is not a tax receipt, deed, title policy, zoning approval or legal survey.

Property-card field	What it helps you check	Important limitation
Owner or taxpayer	The name carried in the assessment account.	Use Recorder records to prove legal ownership.
Property address	The physical or situs location.	It may differ from the tax-mailing address.
Parcel ID and state ID	Exact identifiers for GIS, tax and appeal work.	Copy every digit, dash and suffix.
Land assessment	The assessed value attributed to the land.	Agricultural land uses state-directed valuation rules.
Structures or improvements	The value attributed to buildings and other assessed structures.	“Improvements” does not merely mean recent remodeling.
Total assessed value	Combines applicable land and structure assessments.	This is not the amount of tax owed.
Property characteristics	May show area, grade, condition, age, construction and outbuildings.	Document a material error with measurements or photographs.
Sales disclosure data	Helps identify reported property transfers and sales.	Use the Recorder for the actual deed or mortgage.
Tax district or cap allocation	Helps explain taxing units and constitutional cap treatment.	The official tax statement controls the final calculation.

Parcel-map limitation: Boone County GIS lines are not precise enough to settle a boundary, fence, tree, easement or encroachment dispute. Use recorded documents and a licensed surveyor.

How to Read the 2026 Form 11 Assessment Notice

Indiana Form 11 reports an assessment change. The form itself states that it is not a tax bill.

Fields to verify

Parcel or identification number.
Property address and legal description.
Previous land assessment.
New land assessment.
Previous structure assessment.
New structure assessment.
Previous and new total assessment.
Reason for the revision.
Assessment effective date.
Appeal deadline printed on the notice.

What the notice does not mean

It does not require an immediate tax payment.
The total assessment is not the tax bill.
An increase does not reveal the exact future tax increase.
“Improvements” means assessed structures.
The tax effect occurs in a later pay year.
Deductions and tax caps are applied elsewhere in the process.

2026 notice status: Boone County mailed Form 11 notices on April 28, 2026. The county published June 15, 2026 as the filing deadline for a timely assessment appeal.

Official Indiana Form 11 Open Form 11 PDF

Why a Boone County Assessment May Have Changed in 2026

A higher value is not necessarily caused by a recent sale or a new structure. Indiana assessments can change through several processes.

Annual market trending

Indiana uses annual adjustment factors to move assessments toward current market conditions between physical inspections.

Updated state cost tables

The Assessor explains that updated state cost schedules contributed to changes shown on 2026 notices.

New construction or deletion

A new house, addition, garage, barn, pool, demolition or property-record correction can change structure value.

Land-value change

Location, use, market evidence, acreage or land classification can affect the land assessment.

Sale or parcel change

A transfer, split, combination, condominium creation or legal-description update can create a new or revised account.

Agricultural base rate

The county reports a state-set 2026 agricultural land base rate of $2,120 per acre before applicable productivity and influence adjustments.

Agricultural-value warning: the statewide base rate is not automatically the final per-acre assessment or the property’s tax. Soil productivity, classification, influence factors, deductions and tax rates can change the result.

January 5, 2027 — common deduction filing deadline

The Auditor states that many applications must be filed or postmarked by January 5 of the following year.

How to Appeal a Boone County Assessment

An assessment appeal challenges value, classification or a property-record issue. It does not challenge the tax rate or ask the Treasurer to waive a bill.

Review the property card and Form 11

Confirm the parcel, land, structures, total assessment, characteristics and stated reason for the change.

Identify the exact disagreement

Examples include market value, incorrect area, condition, grade, property class, omitted demolition or a structure that does not exist.

Complete Indiana Form 130

A separate petition is generally required for each parcel being appealed.

Submit the petition and evidence

Boone County accepts appeals by email, mail or in person. Keep the sent email, return receipt, postmark or counter-stamped copy.

Attend the preliminary informal meeting

The taxpayer and assessing official exchange information and attempt to resolve the disagreement.

Continue to PTABOA if unresolved

The Property Tax Assessment Board of Appeals schedules a hearing and mails the hearing notice.

Current filing status: the June 15, 2026 deadline has passed. Contact the Assessor immediately if a timely petition was submitted, a notice was not received or an existing appeal has not progressed.

Official Boone County appeal page and state petition

Review Boone County Appeal Process Open Form 130

PTABOA Hearing and State Appeal Rules

Indiana’s current appeal flowchart contains several procedural deadlines that are easy to miss after Form 130 is filed.

Appeal stage	Current state procedure	Practical action
Separate parcels	A separate Form 130 is required for each parcel.	Do not combine multiple parcel IDs into one petition unless instructed.
Informal result	The informal meeting result is documented on Form 134.	Review every value and condition before signing an agreement.
PTABOA hearing timing	When no agreement is reached, PTABOA generally must hold a hearing within 180 days.	Track the filing date and contact the Assessor when the case remains unscheduled.
Hearing notice	The taxpayer generally receives at least 30 days’ notice.	Verify the mailing address and calendar the hearing immediately.
Continuance	A continuance request generally must be filed at least 10 days before the hearing.	Request it in writing and retain proof.
Determination without hearing	A written request generally must be filed at least 20 days before the hearing.	Submit the complete evidence file with the request.
Failure to appear	An unexcused failure to appear can result in a $50 penalty when statutory conditions are met.	Contact the board before the hearing when attendance becomes impossible.
PTABOA decision	The county issues the determination on Form 115.	Save the mailing envelope because the mailing date controls the next deadline.
Indiana Board appeal	Form 131 generally must be filed within 45 days after the PTABOA order.	File with the Indiana Board and send the required copy to the other party.
Appraisal requirement	A professional appraisal is not required to pursue the appeal.	Use the most relevant evidence available rather than abandoning the case.

Burden-of-proof issue: Indiana law can place the burden on the assessing official when an assessment increased by more than 5% over the prior finally determined value, subject to statutory exceptions and the facts of the case.

Prepare a Useful Assessment Appeal File

Market-value evidence

Recent arm’s-length purchase documents.
Comparable property sales.
A licensed appraisal already obtained.
Written purchase offers when relevant.
Adjustments for size, age, condition and location.
Income and expense information for income-producing property.
A clearly supported requested value.

Factual-error evidence

Measurements and floor plans.
Photographs of condition or damage.
Building permits or demolition records.
Contractor estimates.
Recorded plat or survey.
Evidence of an incorrect property class.
A numbered list of requested corrections.

One-page case summary

Parcel ID, state ID and property address.
Assessment year being appealed.
Current land, structure and total assessment.
The exact issue being disputed.
The requested value or correction.
A numbered exhibit list.
One sentence explaining what each exhibit proves.
Proof that Form 130 was filed on time.

“I am appealing the 2026 assessment of parcel [number]. I request [value or correction] because the record overstates or incorrectly describes [specific issue]. Exhibit 1 shows the factual problem, Exhibit 2 provides market evidence and Exhibit 3 supports the requested result.”

Taxes while an appeal is pending: Indiana guidance permits a taxpayer in some pending appeals to pay based on the immediately preceding year’s assessment. The required amount must still be paid by each installment deadline to avoid delinquency. Confirm the account-specific amount with the Treasurer or professional adviser.

Correction of Error or Formal Appeal?

A simple factual or administrative mistake may be handled differently from a disagreement over market value.

Issue	Likely first route	Evidence to prepare
Wrong square footage	Ask the Assessor whether a property-record correction is available.	Measurements, plans, permit or appraisal.
Demolished building still listed	Report the factual error promptly.	Demolition permit, dated photographs or contractor records.
Incorrect mailing address	File the Auditor’s required address-change form.	Parcel information and authorized signature.
Wrong owner after a recent purchase	Confirm the deed with the Recorder, then contact the Auditor or Assessor.	Recorded instrument number and closing information.
Value exceeds market value	File a timely Form 130 appeal.	Sale, comparable, appraisal or income evidence.
Missing homestead deduction	Contact the Auditor.	HC10 filing confirmation and residence information.

Do not rely on an informal phone call when a deadline is approaching. File the required form on time unless the responsible county office confirms in writing that another procedure protects your rights.

Assessment Year and Property-Tax Pay Year Are Different

Indiana property taxes are paid in arrears. This creates a one-year gap between the assessment year and the normal tax pay year.

2026 assessment

The Form 11 mailed in 2026 reports the assessment for the 2026 assessment year. That value generally affects taxes payable in 2027.

Taxes paid in 2026

The May 11 and November 10, 2026 installments are generally described as 2025-pay-2026 property taxes.

Comparison mistake: do not compare a 2026 Form 11 directly with a 2026 tax payment without checking the assessment year, pay year, deductions, tax rates and cap credits.

Search, Pay and Verify Boone County Property Taxes

Locate the correct parcel

Use the parcel ID from GIS or the tax statement. Confirm every parcel included in the payment.

Confirm the pay year and installment

For 2026, the state lists May 11 and November 10 as the installment dates.

Review prior balances

Check whether an earlier installment, penalty, returned payment or separate parcel remains unpaid.

Compare payment methods and fees

Review office, mail, card, phone and ACH options before submitting payment.

Save proof and verify posting

Keep the parcel, pay year, amount, transaction number, receipt and mailing evidence.

Payment methods and current listed fees

Payment route	Official county guidance
Treasurer counter	The office accepts cash, personal check, cashier’s check, certified check and money order.
Credit or debit card	Cards are processed through the online service. The listed fee is 2.95% with a $1.95 minimum.
ACH or electronic check	The county lists a flat $0.95 fee.
Telephone payment	The published payment number is 1-877-886-1892.
Mail	Identify every parcel and obtain a USPS postmark or other accepted proof.
Bank bill pay	The Treasurer does not recommend it because a bank envelope may lack the required USPS postmark.
Partial payment	Partial payments are accepted, but they do not extend the installment deadline for the remaining amount.

Postmark trap: a private postage-meter date is not a USPS postmark. When no acceptable postmark exists, the payment may need to reach the Treasurer by the deadline.

Mortgage escrow: confirm the scheduled amount and date with the mortgage servicer, then verify that the payment appears in the Treasurer’s records.

Official Boone County payment information Review Payment Options

Homestead and Other Property-Tax Deductions

Boone County property-tax deductions are administered by the Auditor rather than the Assessor or Treasurer.

Common owner benefits

Homestead and supplemental homestead.
Over-65 deduction.
Over-65 circuit-breaker benefit.
Blind or disabled deduction.
Veteran-related benefits.
Solar, wind, geothermal or hydroelectric deduction.
Heritage barn and rehabilitation deductions.

General filing timing

Many real-property applications must be completed and dated during the qualifying year and filed or postmarked by January 5 of the following year.

After a deed change

The Auditor recommends checking or re-filing deductions after a title change because a transfer can affect the account or eligibility.

New-home deduction checklist

Confirm that the deed has recorded.
Save the parcel and state parcel numbers.
Confirm the property is the principal residence.
Check whether a homestead deduction is already active.
File the official HC10 when required.
Keep the filing confirmation.
Review the next tax statement for the deduction and 1% cap allocation.

Mortgage-deduction update: the Auditor’s current notice says the former standalone $3,000 mortgage deduction was eliminated and combined with homestead. Older FAQ wording remains on the county site, so verify current treatment directly with the Auditor.

Mailing-address change: the Auditor does not accept a verbal request or an ordinary letter. Use the county’s official address-change form.

Official Boone County deduction forms Open Auditor Forms

2026 Disabled-Veteran Property-Tax Credit Change

Indiana changed its disabled-veteran property-tax benefit system in 2026. Existing deduction recipients cannot assume their benefit will automatically continue.

Who must register?

Anyone currently receiving a disabled-veteran property-tax deduction, as well as a new applicant or qualifying surviving spouse seeking the benefit.

When will it appear?

Approved benefits under the replacement credit program are expected to first appear on 2027 property-tax bills.

Registration checklist

Contact the Boone County Veterans Service Office before filing.
Obtain the current annual VA benefits letter.
Verify the current service-connected disability rating.
Discuss individual-unemployability status when applicable.
Complete the required State Form 51186 process.
Allow the Veterans Service Office to forward approved paperwork to the Auditor.
Register between July 1 and December 30, 2026.
Retain copies and confirm the credit on the 2027 bill.

Benefit amount: the credit depends on factors such as the VA disability rating, individual-unemployability status, wartime service, age and surviving-spouse qualification. Do not rely on an old deduction amount.

Existing recipients must act: the county specifically warns that current deduction recipients must register for the new program to continue receiving a benefit.

Indiana Property-Tax Caps Explained

Property allocation	Constitutional cap	Important detail
Qualifying owner-occupied homestead	1% of gross assessed value	An approved homestead deduction must be on file for the homestead allocation.
Other residential property	2% of gross assessed value	This can include non-homestead homes, apartments and qualifying residential land.
Agricultural land	2% of gross assessed value	Agricultural improvements can receive a different allocation.
Nonresidential real property	3% of gross assessed value	Commercial land and improvements generally fall within this category.
Business personal property	3% of gross assessed value	This is separate from the 2026 acquisition-cost exemption filing rule.

Automatic credit: the circuit-breaker cap credit is calculated automatically. A separate cap application is not required.

Outside the caps: voter-approved referendum taxes and certain local public-question charges are not included when calculating the cap credit.

Mixed allocation: one parcel can contain more than one cap category. A home, excess land, agricultural improvement or commercial use may receive separate treatment.

Official Boone County property-tax cap explanation Review Property-Tax Caps

2026 Business Tangible Personal Property Rules

Indiana business personal property is a self-assessment system. A business is responsible for obtaining and timely filing its forms.

What may be reportable?

Examples include tools, machinery, computers, printers, furniture, signs, security equipment, display cases and farm equipment used to produce income.

2026 exemption threshold

Beginning in 2026, taxpayers with less than $2 million of county-level acquisition cost can qualify for an exemption, but an annual filing is still required.

Filing needed for the exemption

File Form 104.
Attach Form 103-S, Form 103-L or the first page of Form 102, as applicable.
File by May 15 each year.
Do not assume the exemption removes the filing obligation.
Keep proof of delivery or electronic filing.
Boone County does not permit filing extensions.

Published late-filing penalties

When the return is received	Published penalty
On or before May 15	$0
May 16 through June 15	$25
June 16 through November 15	$25 plus the lesser of 10% of tax due or $10,000.
After November 15	$25 plus the lesser of 20% of tax due or $50,000.
No return received	$25 plus 20% of tax due.

Estimated assessment: when no required return is filed, the county may issue Form 113/PP using an estimated assessment. The taxpayer generally has 30 days from the notice to file a return correcting the estimate.

Cyclical Reassessment and Field-Visit Safety

Indiana requires counties to physically inspect and reassess approximately 25% of their properties each year during a four-year cycle.

What field personnel may do

Come to the door and introduce themselves.
Explain the reason for the visit.
Request permission to walk around the property.
Review additions, deletions and building changes.
Take exterior property photographs.
Leave a door hanger if more information is needed.

What they should not request

Entry into the home.
Interior access to another building.
An immediate tax payment.
