CCH Tax Day Report
A Montana personal income tax deduction has been enacted for taxpayers who, in determining federal adjusted gross income, reduced their business deductions because a federal tax credit was elected. Under the new provision, which applies to tax years beginning after December 31, 2018, a taxpayer is allowed to deduct the amount of the business expense paid when there is no corresponding state income tax credit or deduction, regardless of the credit taken.
