Indiana vs. Kentucky Commercial Property Tax

The short version

Indiana’s constitution caps commercial property-tax bills at 3% of a property’s gross assessed value — a “circuit breaker” that can’t be changed without a statewide vote. Kentucky’s constitution (Section 172) instead requires property to be assessed at 100% fair cash value every year, with no equivalent cap on the resulting bill. Today the effective rates in the two states are similar, so the real difference is predictability: an Indiana commercial owner has a known ceiling on the tax bill; a Kentucky owner’s bill moves with the market value the assessor sets each January 1.

How Indiana caps commercial property tax (the 3% circuit breaker)

Indiana voters amended the state constitution in 2008 (fully phased in by 2010) to cap property-tax bills as a percentage of gross assessed value: 1% for owner-occupied homes, 2% for other residential and farm ground, and 3% for commercial, industrial, and business personal property (Indiana Constitution, Article 10, Section 1; implemented through IC 6-1.1-20.6 and administered by the Department of Local Government Finance). These limits are called “circuit breakers” because they trip automatically — once a tax bill would exceed the cap, the excess is credited off the bill. Because the cap lives in the constitution, it can’t be raised by a city, county, or the legislature alone; it would take a statewide vote to change.

How Kentucky assesses commercial property (fair cash value, no cap)

Kentucky takes a different approach. Section 172 of the Kentucky Constitution requires the local Property Valuation Administrator (PVA) to assess all real property at 100% of its fair cash value as of January 1 each year. “Fair cash value” is essentially fair market value — what the property would sell for between a willing buyer and seller. There is no constitutional circuit-breaker cap on the resulting commercial tax bill the way Indiana has; when market values rise and a reassessment follows, the bill can rise with it.

What the difference actually means for an owner

Be precise here, because the headline can mislead:

• Effective rates are similar today. Statewide, Indiana and Kentucky land in roughly the same range on effective commercial property-tax rates. So this is not “Indiana is far cheaper.”
• The real edge is predictability and a ceiling. Indiana’s 3% cap gives a commercial owner a known maximum carrying cost relative to assessed value — useful for underwriting, holding, and planning. Kentucky’s annual fair-cash-value reassessment offers no comparable ceiling.
• The cap limits the bill, not the assessment. Indiana can still assess your building at full value; the cap only limits what you pay. That’s why appeals still matter in Indiana even when the cap is engaged.

Why this matters when you’re deciding to sell or hold

For an owner weighing a sale, a refinance, or where to put the next dollar, carrying-cost predictability is part of the math — especially on a building that’s vacant, half-leased, or not currently covering its costs. It’s also one of the reasons a local buyer who works both sides of the river can move with more certainty: payoffs, liens, recording, and the property-tax picture all differ across the Indiana–Kentucky line, and knowing those differences is part of reviewing a building accurately.
