Boone County Homestead Deduction And Tax Caps Explained

Buying a home in Zionsville and trying to make sense of Indiana property taxes? You are not alone. Between homestead deductions, assessed values, and the state’s 1%/2%/3% caps, it can feel like a maze. This guide breaks it down in plain language so you know what to file, how the caps work, and how all of it affects your mortgage escrow. Let’s dive in.

Indiana property tax caps, explained

How your tax bill is calculated

Local governments set budgets called tax levies. Those levies, divided by the tax base, create tax rates. Your tax bill is then calculated by multiplying the tax rate by your property’s taxable assessed value.

Deductions and exemptions, like the homestead deduction, reduce your taxable assessed value before taxes are calculated. Counties also reassess property values on a regular schedule to keep assessments up to date.

What 1%/2%/3% caps mean

Indiana law caps the amount of property tax you pay based on your property’s gross assessed value, not the taxable value after deductions.

• Homestead, your owner-occupied primary residence, is capped at 1% of gross assessed value.
• Other residential, such as rentals or second homes, is capped at 2%.
• All other real property, including commercial, industrial, and agricultural, is capped at 3%.

These caps are applied after the county calculates taxes. If your uncapped bill is higher than the cap amount, your bill is reduced down to the cap.

Key terms you should know

• Gross assessed value (GAV): The base value used for the state caps. Caps are a percentage of this number.
• Taxable assessed value: Your assessed value after deductions and exemptions. Taxes are calculated on this value before the cap is applied.
• Cap: The maximum property tax you can be billed, equal to the cap percentage multiplied by your property’s gross assessed value.

A few nuances to keep in mind

Certain special levies, local fees, or school referendum items may be handled differently in cap calculations. Rules can change, so confirm details with the Indiana Department of Local Government Finance or the Boone County Auditor if you have a specific question about what is or is not subject to the cap.

The homestead deduction in Boone County

What it is and who qualifies

The homestead deduction is an owner-occupancy benefit that reduces your taxable assessed value on your primary residence. To qualify, you must live in the home as your primary residence and meet county filing requirements. Other exemptions or credits, such as veteran or senior benefits, are separate and may be additive depending on county and state rules.

How the homestead deduction works with caps

The homestead deduction lowers your taxable assessed value before the county calculates your tax bill. After that, the caps are applied by comparing your bill to a percentage of your gross assessed value. Since the cap is tied to gross assessed value, not taxable value after deductions, both the deduction and the cap can reduce your final bill. They work together, not in conflict.

Why it matters for Zionsville homeowners

If you live in your Zionsville home as your primary residence, filing for the homestead deduction can lower your tax bill by reducing the taxable portion of your assessed value. If your calculated tax is still higher than the state’s 1% homestead cap, the cap can lower it further. Taking both into account helps you estimate yearly taxes and plan your housing budget with confidence.

How to file your homestead deduction in Boone County

Simple filing steps

1. Confirm eligibility. You occupy the property in Zionsville as your primary residence.
2. Get the application. Obtain the homestead deduction form from the Boone County Auditor’s office or website.
3. Gather documents. Common items include proof of ownership (deed or closing statement), government ID, and proof of occupancy, such as a driver’s license with the property address or a recent utility bill.
4. Submit your application. File with the Boone County Auditor by the county’s accepted method, which may include in person, by mail, or a secure online option, and by any stated deadline.
5. Save your records. Keep a copy of your submission and approval. Check your next tax statement to confirm the deduction appears.

What to expect after you file

The Auditor’s office reviews your application. If approved, the deduction will appear on a future tax bill. Processing time can vary, especially if you file around closing. If you have a mortgage, your lender may adjust escrow once the updated tax bill is posted.

Common pitfalls to avoid

• Assuming the seller’s homestead status transfers automatically. Buyers usually need to file their own application.
• Missing deadlines and expecting a retroactive credit. File as soon as you are eligible.
• Leaving out documentation. Incomplete submissions can delay approval.

If you have questions about forms, deadlines, or status, contact the Boone County Auditor. For questions about assessed values or property classification, the Boone County Assessor can help.

Taxes and your mortgage escrow

How lenders set escrow at closing

Your lender estimates property taxes and homeowners insurance to calculate a monthly escrow payment. The estimate usually comes from the most recent tax bills available or county-reported values. Under federal rules, lenders perform an annual escrow analysis to check for shortages or overages and then adjust your monthly payment.

When a deduction or cap lowers your taxes

If your homestead deduction is approved or the 1% homestead cap lowers your tax bill after your lender set escrow, your account may show a surplus. During the next annual analysis, lenders typically refund overages or credit them to future payments. If you receive an updated tax bill mid-year, you can ask your servicer for an interim escrow review.

What you should do

• Send proof. After the deduction appears on your tax bill, share the new bill or approval with your mortgage servicer.
• Request a reanalysis. Ask your lender when they will adjust your payment and whether you qualify for an earlier review.
• Track timelines. Lenders follow federal servicing rules on escrow analyses and refunds. Keep copies of all correspondence.

A simple example (hypothetical)

• Gross assessed value: $300,000
• Uncapped tax before deduction: $6,000
• Homestead cap at 1% of gross assessed value: $3,000

If the uncapped bill is $6,000 but the homestead cap applies, your final bill would be limited to $3,000. If your lender estimated $6,000 at closing, your escrow could end up with a $3,000 surplus for that year, which is typically refunded or credited after reanalysis. Your actual numbers will vary based on Boone County assessments, deductions, and rates.

Buyer and seller tips at Zionsville closings

Putting it all together

In Zionsville and across Boone County, two things drive your final tax bill. First, the homestead deduction reduces your taxable assessed value if you live in the home as your primary residence. Second, the state’s 1% homestead cap can further limit your tax bill based on your property’s gross assessed value. When you understand both, you can estimate your taxes more accurately, set your escrow correctly, and avoid surprises.

If you are planning a move, buying a home, or reviewing tax estimates on your current place in Zionsville, start by confirming eligibility and filing your homestead deduction. Then watch for the updated bill and ask your lender to recheck escrow. A little proactive effort can keep your monthly payment on track.
