Household income is the adjusted gross income from your tax return plus any excludible foreign earned income and tax-exempt interest you receive during the taxable year. Household income also includes the incomes of all of your dependents who are required to file tax returns because their income meets the filing threshold. Household income does not include a dependent's income if the dependent's income is below the filing threshold, even if he or she chooses to file a return for another reason (for example to claim a refund of withheld income tax).
