  • Office: +74%
  • Apartment: +77%
  • Light Manufacturing: +130%

Why This Matters

Indiana relies on cost schedules as a key component in determining the market value-in-use for assessment purposes. As these schedules increase, assessed values typically follow, particularly when trend factors remain in place.

For businesses, this may result in:

  • Higher assessed values for 2026, leading to increased tax bills in 2027
  • Material shifts in tax liability, especially for manufacturing and other cost-sensitive properties

Why Expert Guidance is Critical

Businesses in Indiana must understand these increases, evaluate how these changes impact their specific properties, and act within Indiana’s strict appeal deadlines.

Waiting until tax bills are issued limits your options.
