Enrolled Senate Bill (S) → Senate Bill (S) · 5 edits

MODERATE

This bill fundamentally transforms the legislative text from a finalized 'Enrolled Act' into a draft 'Senate Bill' by removing all enacted language and replacing it with a new proposal. The substantive content has been completely rewritten to shift focus from county vehicle taxes to state transportation contracting, federal environmental authority, and contractor liability protections.

Scope change

The bill's scope has shifted entirely from local government taxation (county vehicle excise taxes) to state-level transportation administration, federal environmental compliance, and construction project liability.

SCOPE

All provisions regarding county vehicle excise taxes, wheel taxes, and surtax rates were completely removed.

New provisions allow the Indiana Department of Transportation to assume federal environmental responsibilities and waive civil immunity for those duties.

ADDED

New protections exempt contractors providing engineering inspection services from civil or criminal liability for third-party motor vehicle accident claims.

REQUIREMENT

New rules clarify that the Indiana Plane Coordinate System is an acceptable method for describing real property.

TIMELINE

The document structure changed from a finalized law (Enrolled Act) to a draft bill (Senate Bill) with updated dates and committee referral information.

Engrossed Senate Bill (S) → Enrolled Senate Bill (S) · 5 edits · Mar 12, 2026

MODERATE

This bill transitions from an 'Engrossed' draft to an 'Enrolled' final version, incorporating significant policy updates to Indiana's vehicle excise tax laws. The most critical change is the expansion of tax rates and surcharge amounts for counties that use approved transportation asset management plans, increasing the maximum rate from 20% to 20% (with a specific dollar cap rising from $50 to $150) and allowing higher surcharges for counties without such plans. Additionally, new eligibility requirements and deadlines were added to ensure counties adopt these taxes by specific dates to qualify for state funding distributions.

Scope change

The bill's scope expanded to include stricter eligibility criteria and specific deadlines for counties to adopt vehicle excise taxes in order to receive state funding distributions, while also increasing the financial limits on those taxes.

FISCAL

Increased the maximum specific surcharge amount for counties using approved transportation plans from $50 to $150 per vehicle.

Adjusted the maximum surcharge rate for counties without approved plans, maintaining a 20% cap but clarifying the specific dollar minimums.

TIMELINE

Added new deadlines requiring counties to adopt vehicle excise taxes by May 1, 2026, or September 1 of the prior year, to be eligible for state funding distributions.

REQUIREMENT

Clarified that counties must concurrently adopt wheel tax ordinances to impose or rescind vehicle excise taxes.

TECHNICAL

Removed draft metadata, including the 'Engrossed' title, digest summaries, and legislative history notes, as these are not part of the final enacted law.
