A boarder is a nonparticipant who pays someone for providing a room and meals. (See Boarders-NA)
Income received from a boarder who is not included in the budgetary unit is countable and is considered self-employment when it meets the self-employment definition.
When the self-employment definition is not met, consider another type of earned income.
When expenses are incurred, see Allowable Business Expenses.
