Revise individual income tax rates and earned income credit
SB 323 would reduce Montana's top individual income tax rate from 5.9% to 4.9% for most taxpayers, including married couples filing jointly, heads of household, and single filers. It also increases the state's Earned Income Tax Credit, providing greater tax relief for low-to-moderate income workers. The bill amends Montana's tax code (sections 15-30-2103 and 15-30-2318) to adjust tax brackets and credit amounts, with changes applying to income above specific thresholds ($41,000 for joint filers, $30,750 for heads of household, and $20,500 for others). The bill was tabled in committee and died in process without becoming law.
