Bill Summary · HB 6001

Overview

HB 6001, introduced in the Michigan House in May 2026, would require the state to create and maintain an online property tax calculator. The calculator would be a joint effort of the Department of Treasury and the Department of Technology, Management, and Budget (DTMB) and would be accessible to the public at no cost. It expands and modernizes the department’s existing millage rate database and property tax estimator, including the capability to estimate taxes based on street addresses and to compare taxes and millage rates across local units statewide.

Purpose and intent

  • Provide a publicly accessible, online tool to help individuals and businesses estimate current property taxes.
  • Enable users to compare property tax burdens and local millage rates across Michigan’s local units.
  • Preserve and enhance the functionality of the existing online millage rate database and property tax estimator, with added features (notably address-based estimates).

Key provisions

  • Joint obligation: The Department of Treasury and the DTMB must jointly develop, maintain, and provide the online property tax calculator.
  • Public access: The calculator must be available to the public free of charge.
  • Definitional scope: The term “online property tax calculator” is defined to include:
    • An online millage rate database and property tax estimator.
    • Capabilities identical to the existing online millage rate database and property tax estimator previously provided by the Department of Treasury.
    • Additional capability to estimate property taxes using the street address of the property.
  • Effective date: The act takes effect 180 days after enactment.

Who is affected

  • Michigan residents and business taxpayers who own property and pay property taxes.
  • Local government units (implicitly, as the tool would enable comparison of millage rates across units).
  • State agencies (Department of Treasury and DTMB) responsible for developing, hosting, and maintaining the calculator.

Procedural and timeline aspects

  • Enactment: The bill specifies an effective date 180 days after the act is enacted into law.
  • Authorization: Requires collaboration between two state departments (Treasury and DTMB).
  • Legislative status: Introduced May 20, 2026; referred to the Committee on Government Operations for consideration.

Potential impact

  • Increased transparency: Taxpayers can more easily understand and compare property tax obligations across local units.
  • Tax planning: Businesses and individuals can estimate taxes more quickly, supporting financial planning and decision-making.
  • Accessibility: A free, online tool lowers barriers to accessing property tax information.
  • Administrative alignment: Keeps and expands existing state tools, potentially improving consistency in tax estimation.

If you’d like, I can add a plain-language example showing how a user would estimate taxes for a specific address using the proposed calculator.
