Montana Personal Income Tax Laws

No one likes to pay income taxes each year, but taxation is necessary for federal and state governments to operate and provide services for residents. While the vast majority of states collect a personal income tax, similar to that collected by the federal Internal Revenue Service (IRS), it's usually a much smaller bill. State tax returns are due the same time as federal returns (April 15 of each year, unless it falls on a holiday or weekend), and often are calculated together. Most states now offer electronic (online) filing of tax returns in addition to the traditional paper filing.

Not all income is taxable, but includes money from salaries and wages, dividends and stock profits, and other sources. Income such as child support payments, welfare, and some retirement funds may not be taxed.
