You should report the current, gross, taxable income for your household.
A "household" includes 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 house-mates, if you do not share any other financial responsibilities with them.
If you do not participate in the tax system because of rules in your area, please refer to the What if I am unable to provide you with a tax return? FAQ article for more information.
