A "household" refers to you and anyone who helps support you financially. If you share responsibility for paying for your housing, living expenses, and other necessities with a partner or spouse, you must include their income. If some or all of your expenses are paid for by someone else, for example, parents or guardians, you must report their income as well.
If you pay for all of your own housing, living expenses, and other necessities then please report only your income.
You do not need to report the income of anyone you support financially, such as children. You do not need to include the income of other adults with whom you share housing expenses, such as room or housemates, if you do not share any other financial responsibilities.
