The Qualified Business Income Deduction—also known as the Section 199A deduction—was introduced under the Tax Cuts and Jobs Act and applies to tax years beginning after December 31, 2017, and ending on or before December 31, 2025. It allows eligible owners of pass‑through businesses to deduct up to 20% of their qualified business income, plus 20% of qualified REIT dividends and publicly traded partnership income.
This deduction is available whether you itemize or take the standard deduction, making it one of the most accessible tax benefits for small‑business owners.
Who Qualifies for the QBI Deduction?
The deduction applies to income from:
- Sole proprietorships
- Partnerships
- S corporations
- LLCs taxed as any of the above
- Certain trusts and estates
Income earned as a W‑2 employee or through a C corporation does not qualify.
Service Businesses and Income Limits
Some service‑based businesses—called Specified Service Trades or Businesses (SSTBs)—face additional restrictions. These include fields such as accounting, consulting, law, health, financial services, athletics, and performing arts.
For SSTBs, the deduction phases out once taxable income exceeds certain thresholds. At higher income levels, the deduction may be reduced or eliminated entirely.
What Counts as Qualified Business Income?
Qualified Business Income (QBI) includes the net amount of qualified items of income, gain, deduction, and loss from any qualified trade or business. This generally includes:
- Business profit
- Deductible part of self‑employment tax
- Self‑employed health insurance
- Retirement plan contributions (SEP, SIMPLE, qualified plans)
QBI does not include:
- Capital gains or losses
- Dividend income
- Interest income not properly allocable to the business
- W‑2 wages paid to S‑corp owners
- Guaranteed payments to partners
- Income earned outside the U.S.
How the QBI Deduction Is Calculated
The deduction has two components:
1. QBI Component
This equals 20% of qualified business income from a domestic business operated as a sole proprietorship, partnership, S corporation, trust, or estate.
However, this amount may be limited by:
- Taxpayer’s taxable income
- W‑2 wages paid by the business
- Unadjusted basis immediately after acquisition (UBIA) of qualified property
- Whether the business is an SSTB
2. REIT/PTP Component
This equals 20% of qualified REIT dividends and publicly traded partnership income.
This portion is not limited by W‑2 wages or UBIA.
Overall Limitation
The total deduction cannot exceed 20% of taxable income minus net capital gains.
What About Rental Real Estate?
Rental real estate may qualify for the QBI deduction if it rises to the level of a trade or business. The IRS provides a safe harbor that allows certain rental activities to be treated as a business if specific requirements are met. Even if the safe harbor is not met, rental income may still qualify if it meets the general definition of a trade or business.
Income Thresholds and Phaseouts
The qualified business income deduction is straightforward for taxpayers below certain income thresholds. Once income exceeds those limits, additional tests apply.
For SSTBs, the deduction begins to phase out once taxable income exceeds the IRS‑defined threshold and may be eliminated entirely at higher levels. For non‑SSTBs, the deduction may still be limited by W‑2 wages and UBIA of qualified property.
How to Claim the QBI Deduction
Taxpayers claim the deduction on their individual tax return using:
- Form 8995 (for simpler situations)
- Form 8995‑A (for more complex calculations)
The deduction is taken below the line, meaning it reduces taxable income but not adjusted gross income (AGI).
Tax software such as TurboTax automatically calculates the deduction based on business income entered, but taxpayers should still review adjustments for capital gains, losses, and other factors.
Strategies to Maximize the QBI Deduction
1. Manage Taxable Income
Staying below the income threshold can preserve the full 20% deduction especially important for SSTBs.
2. Increase W‑2 Wages (If Applicable)
For high‑income owners of non‑SSTBs, increasing W‑2 wages may help maximize the deduction.
3. Invest in Qualified Property
UBIA of qualified property can increase the allowable deduction for high‑income taxpayers.
4. Review Entity Structure
S‑corp vs. sole proprietorship can affect W‑2 wages and QBI eligibility.
5. Track All Deductible Expenses
Retirement contributions, health insurance, and other deductions reduce QBI but may help keep taxable income within qualifying limits.
Final Thoughts
The Qualified Business Income Deduction remains one of the most powerful tax‑saving opportunities for small‑business owners and self‑employed individuals. With the ability to deduct up to 20% of business income, understanding how the deduction works and how to optimize it can significantly reduce your tax liability through 2025.
