Frequently Asked Friday: Indiana Property Taxes — Part 4 of 5

Why Did My Property Taxes Go Up When I Haven’t Changed Anything?

It’s a question I hear often, and it’s a reasonable one.

You haven’t added a room. You haven’t built a garage. You haven’t made any major improvements. Yet your property tax bill arrives, and the amount has changed.

How does that happen?

The answer is that your property taxes are influenced by more than just what you’ve done to your home.

1. Your Property’s Assessed Value Can Change Without Improvements

As we discussed in Part 2, Indiana uses a system called annual trending to adjust property assessments based on real estate market activity.

If comparable homes in your area have been selling for higher prices, your assessed value may increase even if you haven’t changed a thing about your property.

That doesn’t mean your home was individually appraised or that someone decided you should pay more taxes. It means the assessor is using market information to estimate values across groups of properties.

An increase in assessed value does not necessarily mean your tax bill will increase by the same percentage.

2. Local Government Budgets and Tax Rates Matter

Property taxes help fund services provided by local taxing units, including schools, counties, townships, cities, towns, libraries, and other applicable districts.

Those taxing units establish budgets and property tax levies under Indiana law. Tax rates are then calculated using the amount to be raised and the taxable assessed value within the taxing district.

Here’s something homeowners don’t always realize:

Your assessed value can stay the same while your property tax bill changes.

That’s because the tax rate, applicable credits, or other factors may change.

Likewise, your assessed value can increase while the tax rate decreases.

There are several moving parts.

3. Property Tax Caps Don’t Mean Your Bill Can’t Increase

Indiana has constitutional property tax caps commonly referred to as the circuit breaker caps.

Generally, these are:

1% for qualifying homesteads
2% for other residential property and agricultural land
3% for commercial and industrial property

But here’s an important distinction.

The percentages are based on a property’s gross assessed value, not last year’s tax bill.

For example, if a qualifying homestead’s gross assessed value increases from $200,000 to $220,000, its 1% cap calculation changes from $2,000 to $2,200.

That doesn’t mean the homeowner will necessarily owe either amount. Deductions, credits, actual tax rates, and other applicable rules still matter.

It simply illustrates why a tax cap is not a guarantee that your bill will remain unchanged.

Certain voter-approved taxes may also fall outside the caps.

4. Deductions and Credits Can Change the Final Amount

In Part 3, we talked about the deductions, credits, and exemptions that may help reduce a homeowner’s property tax liability.

Those benefits matter when calculating the final bill.

Changes in eligibility, applicable tax relief, or state law can affect what you owe.

Indiana has also made significant changes to property tax deductions and credits in recent legislation, making it especially important to review your tax statement rather than assume the calculation works exactly as it did several years ago.

So What Should You Do If Your Bill Increases?

First, don’t assume the increase is automatically an error.

But don’t assume it’s correct without looking at it, either.

Compare your current and previous tax statements. Look at your assessed value, your taxing district’s rate, your deductions, and your credits.

If the assessed value seems inaccurate, contact your county assessor to discuss the assessment and the appeal process.

If you’re questioning a deduction, credit, payment, or the calculation of your tax bill, your county auditor or treasurer may be the appropriate starting point, depending on the issue.

The important thing is to understand what changed before deciding what to do next.

My Final Thought

As a REALTOR®, I spend a great deal of time talking with people about property values.

But property value and property taxes are not the same thing.

A change in one doesn’t always produce an equal change in the other.

Understanding the difference can help homeowners ask better questions, identify possible errors, and make more informed decisions.

Next Friday, we’ll wrap up our five-part series with practical steps for reviewing your assessment and tax bill, finding public records, and knowing where to turn when something doesn’t look right.
