The Qualified Business Income deduction (also called the QBI deduction, pass-through deduction, or section 199A deduction) lets most self-employed taxpayers and small business owners exclude up to 20% of their qualified business income (QBI) from federal income tax.

The deduction amount depends on the taxpayer's total taxable income and the type of business. At higher income levels, the deduction is reduced or eliminated.

For the purposes of the deduction, QBI is defined as net business income, excluding:

  • Income generated outside the United States

  • Investment income

  • W-2 compensation paid to an S corporation owner

  • Guaranteed payments to a partner

  • Income from REITs, publicly traded partnerships, and qualified cooperatives (these entities may qualify for a 20% deduction under a different set of rules, the explanation of which is beyond the scope of this article)

TurboTax automatically calculates the QBI deduction using the business income entered. Keep an eye out for adjustments needed for things like capital gains or losses.

What types of businesses does this deduction apply to?

This deduction applies to Schedule C filers (sole proprietorships and other self-employed businesses), LLCs, partnerships, S corporations, estates, and trusts. Certain rental enterprises may also qualify.

Some types of service businesses (SSTBs) are disqualified once the taxable income on the return exceeds $247,300 ($494,600 if filing jointly). At higher income levels, the deduction for SSTBs is reduced and in some cases, eliminated.

For the purposes of the QBI deduction, an SSTB is defined as any trade or business that performs services in the fields of:

  • Accounting

  • Actuarial science

  • Athletics

  • Consulting

  • Health

  • Law

  • Performing arts

  • Financial services

  • Brokerage services (including investment management and investing, trading, or dealing in securities, commodities, or partnership interests)

Rental real estate qualifying as a business for the QBI deduction

There's a safe harbor allowing certain interests in rental real estate, including interests in mixed-use property, to be treated as a trade or business for purposes of the qualified business income deduction.

If all the safe harbor requirements are met, an interest in rental real estate will be treated as a single trade or business for purposes of the deduction. If an interest in real estate fails to satisfy all the requirements of the safe harbor, it may still be treated as a trade or business for purposes of the deduction if it otherwise meets the definition of a trade or business.
