The QBI deduction and what's new in the One, Big, Beautiful Bill Act

The qualified business income (QBI) deduction, which became effective in 2018, is a significant tax benefit for many business owners. It allows eligible taxpayers to deduct up to 20% of QBI, not to exceed 20% of taxable income. It can also be claimed for up to 20% of income from qualified real estate investment trust dividends.

With recent changes under the One, Big, Beautiful Bill Act (OBBBA), this powerful deduction is becoming more accessible and beneficial. Most important, the OBBBA makes the QBI deduction permanent. It had been scheduled to end on December 31, 2025.

A closer look

QBI is generally defined as the net amount of qualified income, gain, deduction and loss from a qualified U.S. trade or business. Taxpayers eligible for the deduction include sole proprietors and owners of pass-through entities, such as partnerships, S corporations and limited liability companies that are treated as sole proprietorships, partnerships or S corporations for tax purposes. C corporations aren’t eligible.

Additional limits on the deduction gradually phase in if 2025 taxable income exceeds the applicable threshold — $197,300 or $394,600 for married couples filing joint tax returns. The limits fully apply when 2025 taxable income exceeds $247,300 and $494,600, respectively.

For example, if a taxpayer’s income exceeds the applicable threshold, the deduction starts to become limited to:

• 50% of the amount of W-2 wages paid to employees by the qualified business during the tax year, or

• The sum of 25% of W-2 wages plus 2.5% of the cost (not reduced by depreciation taken) of qualified property, which is the depreciable tangible property (including real estate) owned by a qualified business as of year end and used by the business at any point during the tax year to produce QBI.

Also, if a taxpayer’s income exceeds the applicable threshold and the QBI is from a “specified service business,” the deduction will be reduced and eventually eliminated. Examples of specified service businesses are those involving investment-type services and most professional practices, including law, health, consulting, performing arts and athletics (but not engineering and architecture).

Even better next year

Under the OBBBA, beginning in 2026, the income ranges over which the wage/property and specified service business limits phase in will widen, potentially allowing larger deductions for some taxpayers. Instead of the distance from the bottom of the range (the threshold) to the top (the amount at which the limit fully applies) being $50,000, or, for joint filers, $100,000, it will be $75,000, or, for joint filers, $150,000. The threshold amounts will continue to be annually adjusted for inflation.

The OBBBA also provides a new minimum deduction of $400 for taxpayers who materially participate in an active trade or business if they have at least $1,000 of QBI from it. The minimum deduction will be annually adjusted for inflation after 2026.

Pass-Through Deductions

10 facts about the pass-through deduction for qualified business income

Are you eligible to take the deduction for qualified business income (QBI)? Here are 10 facts about this valuable tax break, referred to as the pass-through deduction, QBI deduction or Section 199A deduction. 

1. It’s available to owners of sole proprietorships, single member limited liability companies (LLCs), partnerships and S corporations. It may also be claimed by trusts and estates.

2. The deduction is intended to reduce the tax rate on QBI to a rate that’s closer to the corporate tax rate.

3. It’s taken “below the line.” That means it reduces your taxable income but not your adjusted gross income. But it’s available regardless of whether you itemize deductions or take the standard deduction.

4. The deduction has two components: 20% of QBI from a domestic business operated as a sole proprietorship or through a partnership, S corporation, trust or estate; and 20% of the taxpayer’s combined qualified real estate investment trust (REIT) dividends and qualified publicly traded partnership income.

5. QBI is the net amount of a taxpayer’s qualified items of income, gain, deduction and loss relating to any qualified trade or business. Items of income, gain, deduction and loss are qualified to the extent they’re effectively connected with the conduct of a trade or business in the U.S. and included in computing taxable income.

6. QBI doesn’t necessarily equal the net profit or loss from a business, even if it’s a qualified trade or business. In addition to the profit or loss from Schedule C, QBI must be adjusted by certain other gain or deduction items related to the business.

7. A qualified trade or business is any trade or business other than a specified service trade or business (SSTB). But an SSTB is treated as a qualified trade or business for taxpayers whose taxable income is under a threshold amount.

8. SSTBs include health, law, accounting, actuarial science, certain performing arts, consulting, athletics, financial services, brokerage services, investment, trading, dealing securities and any trade or business where the principal asset is the reputation or skill of its employees or owners.

9. There are limits based on W-2 wages. Inflation-adjusted threshold amounts also apply for purposes of applying the SSTB rules. For tax years beginning in 2021, the threshold amounts are $164,900 for singles and heads of household; $164,925 for married filing separately; and $329,800 for married filing jointly. The limits phase in over a $50,000 range ($100,000 for a joint return). This means that the deduction reduces ratably, so that by the time you reach the top of the range ($214,900 for singles and heads of household; $214,925 for married filing separately; and $429,800 for married filing jointly) the deduction is zero for income from an SSTB.

10. For businesses conducted as a partnership or S corporation, the pass-through deduction is calculated at the partner or shareholder level.

As you can see, this substantial deduction is complex, especially if your taxable income exceeds the thresholds discussed above. Other rules apply. Contact us if you have questions about your situation.
