Provide income tax credit for certain long-time residents

This bill creates a $500 income tax credit for Montana residents who have lived in the state for at least 10 years and earn less than $100,000 annually. To qualify, taxpayers must have resided in Montana for at least seven months during each of the prior 10 years, and the credit applies only to income tax years beginning after December 31, 2025. The legislation also requires the revenue interim committee to review this credit, along with other existing tax credits, every eight years to assess whether they should continue or be modified.
