2026 tax preference performance reviews

PLANNED STUDY QUESTIONS | SEPTEMBER 2025


Pete van Moorsel, tax review coordinator | Eric Thomas, legislative auditor


JLARC directed to review tax preferences on 10-year schedule

A tax preference is a reduction in the amount of state tax owed by an industry, business, or individual. Tax preferences include exemptions, exclusions, deductions, credits, deferrals, and preferential state tax rates.

In 2006, the Legislature:

  • Created the Citizen Commission for Performance Measurement of Tax Preferences (Citizen Commission) and directed it to set a 10-year schedule for reviewing tax preferences.
  • Directed JLARC staff to complete the reviews. The Legislative Auditor must recommend actions the Legislature could take for each preference based on the findings of each review.

JLARC's tax preference review fact sheet includes more information.

By law, tax preference reviews must address these study questions

Study questions define the scope of the audit. These reviews will consider the study questions as they relate to each preference.

  • Public policy objectives: What did the Legislature intend to accomplish? Has the preference achieved those goals?
    • The Legislature defined specific performance metrics for some tax preferences.
    • For others, JLARC staff infer objectives and metrics.
  • Beneficiaries: Who does the preference benefit, either directly or indirectly? How much have they saved?
  • Revenue and economic impacts: What are the impacts to the taxpayers and the state?
  • Other states: Do other states have a similar tax preference?
  • Racial equity: Are there racial equity considerations associated with the tax preferences?

JLARC staff will review seven preferences for 2026

The Citizen Commission has scheduled seven tax preferences for review in 2026. The preferences' summary details and specific performance metrics are included below. JLARC staff will report findings, conclusions, and recommendations in July 2026.

Public policy objective

The Legislature stated that its objective for the urban data center tax preference is to:

  • Improve industry competitiveness.
  • Increase, create, or retain jobs in computer data centers in counties with a population of more than 800,000, thereby increasing family-wage jobs.

Performance metric

The Legislature directed JLARC to determine if the tax preference is:

  1. Generating capital investment in new computer data centers, refurbished data centers, or existing data centers (e.g., replacement server equipment).
  2. Generating state and local tax collections from data center investment and operations.
  3. Generating or maintaining construction and trade jobs in the state.

The review must factor in changing economic conditions.


Description

This report will review a credit for business and occupation (B&O) tax or public utility tax for a portion of contributions made to the Main Street Trust Fund or to a specific Main Street program. The Main Street Program aims to help communities revitalize the economy, appearance, and image of their downtown commercial districts.

Total credit claims may not exceed $250,000 per beneficiary or $5 million per year.

  • Ensure the growth and retention of businesses in rural communities.

The Legislature's objective is to support Main Street programs and the revitalization of business districts.

Performance metric

Legislative intent and public policy objective

The Legislature categorized the tax preference as one intended to:

  • Create or retain jobs.
  • Encourage community and economic development within communities that have historically lacked access to capital.
