Indiana property tax reform: What it means for local government credit and why proactive management matters more than ever 

Recent legislative changes to Indiana’s property tax system are poised to reshape the financial landscape for local governments across the state. While the reforms are intended to address taxpayer affordability concerns, they also introduce new fiscal pressures that could materially affect local government credit quality, long-term financial sustainability, and service delivery.

For Indiana municipalities, counties, and school corporations, the message from rating agencies is clear: reduced revenue flexibility increases credit risk, and strong financial management practices will become more critical than ever.

On April 30, 2026, S&P Global Ratings released “Credit FAQ: Is Property Tax Reform a Growing Concern for U.S. Local Government Credit Quality?”, highlighting Indiana as one of the states with stronger potential for negative credit implications.

Key implications for Indiana local governments

Indiana’s enacted reforms (SEA 1 & HEA 1427) expand deductions, credits, and personal property tax exemptions, structurally reducing the property tax base and limiting long-term revenue growth for many local governments.

Unlike some other states, Indiana did not provide transition or backfill funding to offset these changes, leaving local governments to address revenue losses independently.

While local governments may offset some losses through local income tax increases, this approach presents several challenges:

• Income tax increases remain optional
• Political and voter approval risks may complicate adoption
• Revenue replacement may be uneven and uncertain across communities based on income tax capacity

School corporations may face additional pressure as slower property tax growth coincides with new requirements to share property tax revenue with charter schools.

S&P views Indiana’s reforms as more credit-challenging than reforms adopted in many other states, with a stronger likelihood of:

• Budget pressure
• Service reductions
• Reserve drawdowns
