- Wages
- Income from services performed in Montana (for example, doctors, lawyers, accountants, carpenters, painters, hairdressers, piano teachers, etc.)
- Self-employment income (if the spouse is engaged in a personal service business that doesn't make, buy, or sell goods to produce income)
If your nonmilitary spouse earned any other type of income in Montana, he or she should include that income in the Montana amount column.
