Your QBI includes items of income, gain, deduction, and loss from your trades or businesses that are effectively connected with the conduct of a trade or business within the United States. This includes income from partnerships, S corporations, sole proprietorships, and certain trusts that are included or allowed in determining your taxable income for the year. It also includes other deductions attributable to the trade or business including, but not limited to, unreimbursed partnership expenses, business interest expense, deductible tax on self-employment income, self-employed health insurance, and contributions to qualified retirement plans.
Your QBI doesn't include any losses or deductions disallowed under the basis, at-risk, passive loss, or section 461(l) limitations, as they aren't included or allowed in determining your taxable income for the year. Instead, these losses and deductions are taken into account in the tax year they are included in determining your taxable income.
