Deductions

Tax deductions are a reduction in the amount of income that is subject to taxation. It allows taxpayers to lower the amount of taxable income they have, which in turn reduces the amount of tax they owe. Tax deductions are available for a wide range of expenses, such as charitable donations, mortgage interest, medical expenses, and business expenses.

  • Montana has standard deduction based on your level of income and filing status.

Credits

A tax credit allows taxpayers to reduce the amount of taxes they are required to pay. This is different from a tax deduction, which reduces the amount of income that is subject to taxation. Tax credits are applied directly to the tax liability, while deductions are applied to the taxable income.

Exclusions

Tax exclusions are an amount of money or income that is not subject to taxation. This means that taxpayers do not have to pay taxes on this income.
