If you own a small business, you could be missing out on one of the most valuable tax deductions available.
The Section 199A Qualified Business Income (QBI) deduction allows eligible owners of pass-through businesses to deduct up to 20% of their qualified business income from their taxable income. For many business owners, that can mean thousands of dollars in annual tax savings.
Even better, recent legislation has made the deduction permanent, giving business owners greater certainty when planning for the future.
What Is the Section 199A Qualified Business Income Deduction?
The Section 199A deduction was created under the Tax Cuts and Jobs Act of 2017 to give owners of pass-through businesses a tax benefit comparable to the corporate tax rate reduction available to C corporations.
In simple terms, if your business income “passes through” to your personal tax return—as it does for most small businesses—you may be able to deduct 20% of your qualified business income (QBI) before calculating your federal income tax.
Because the deduction is based on several income thresholds and limitations, understanding how the rules apply to your business is essential.
Who Qualifies for the Section 199A QBI Deduction?
The deduction is generally available to owners of pass-through entities, including:
- Sole proprietors (Schedule C filers)
- Partnerships
- S corporations
- Single-member LLCs
- Certain trusts and estates
Who Doesn’t Qualify?
The Section 199A deduction generally isn’t available to:
- C corporation owners, since the corporation pays its own taxes
- W-2 employees, even if they work for a pass-through business
- Individuals whose income consists solely of capital gains, dividends, or interest
If you’re unsure how your business is taxed, Sovereign CPA can help determine whether you’re eligible.
What Counts as Qualified Business Income (QBI)?
Qualified Business Income is generally your net business profit after ordinary and necessary business expenses have been deducted. However, not all business-related income qualifies.
Income Included in QBI
- Operating income from your trade or business
- Certain rental income that meets IRS trade or business requirements
Income Excluded from QBI
- W-2 wages or guaranteed payments you pay yourself
- Capital gains and losses
- Most dividends and interest income
- Investment income unrelated to the business
Knowing what counts and what doesn’t is critical when calculating your deduction accurately.
Section 199A Income Limits for 2025
One of the biggest factors affecting your deduction is your taxable income. For 2025, the rules work as follows:
Below the Income Threshold (Full Deduction Available)
- Single filers: Under $197,300
- Married filing jointly: Under $394,600
If your taxable income falls below these thresholds, you can generally claim the full 20% deduction without additional limitations.
Within the Phase-In Range (Partial Deduction)
- Single filers: $197,300 to $247,300
- Married filing jointly: $394,600 to $494,600
Within this range, the deduction gradually phases down depending on your income and business type.
Above the Upper Threshold
- Single filers: Above $247,300
- Married filing jointly: Above $494,600
Once your income exceeds these limits, additional wage and qualified property limitations apply.
Looking ahead: Beginning in 2026, the One Big Beautiful Bill Act (OBBBA) expanded the phase-in ranges and indexed the thresholds for inflation, so they’ll increase slightly each year.
What About Service Business Owners?
If you own a Specified Service Trade or Business (SSTB), additional rules apply once your income exceeds the thresholds above. SSTBs include businesses in fields such as:
- Law
- Healthcare
- Accounting
- Consulting
- Financial services
- Athletics
- Performing arts
If your taxable income falls below the threshold, you can generally claim the full deduction. If you’re within the phase-in range, a partial deduction may still be available. However, once your income exceeds the upper threshold, the Section 199A deduction is generally unavailable for SSTB income.
The W-2 Wage and Qualified Property Limitation
For higher-income taxpayers, the deduction isn’t automatically equal to 20% of qualified business income. Instead, it’s limited to whichever of the following is greater:
- 50% of the W-2 wages your business paid during the year, or
- 25% of W-2 wages plus 2.5% of the unadjusted basis of qualified business property
For example, S corporation owners often need to balance paying themselves a reasonable salary (which increases the W-2 wage base) while preserving enough qualified business income to maximize the deduction. The right compensation strategy can have a meaningful impact on your overall tax savings.
This is one of the reasons proactive tax planning matters.
What’s New Under the One Big Beautiful Bill Act?
Recent legislation made several important changes to the Section 199A deduction.
The Deduction Is Now Permanent
Originally, Section 199A was scheduled to expire after December 31, 2025. The OBBBA permanently extended the deduction, allowing business owners to incorporate it into their long-term tax planning.
Expanded Phase-In Ranges
Beginning in 2026, the phase-in range increases to:
- $75,000 above the threshold for single filers
- $150,000 above the threshold for married couples filing jointly
This allows more higher-income taxpayers to qualify for at least a partial deduction.
New $400 Minimum Deduction
Business owners who materially participate in an active trade or business and have at least $1,000 of QBI are guaranteed a minimum deduction of $400, even if other limitations would otherwise reduce the deduction to zero.
How to Maximize Your Section 199A Deduction
Because the rules are complex, tax planning can make a significant difference in the amount you’re able to deduct. Some common strategies include:
- Reviewing whether your current business entity is still the most tax-efficient.
- Monitoring your taxable income to stay below important deduction thresholds when possible.
- Investing in qualified business property if the wage and property limitations apply.
- Maximizing retirement contributions, such as SEP IRAs or Solo 401(k)s, to reduce taxable income.
- Reviewing owner compensation if you operate as an S corporation.
Every business is different, so the best strategy depends on your income, entity structure, and long-term goals.
Don’t Leave Tax Savings on the Table
The Section 199A Qualified Business Income deduction remains one of the most valuable tax benefits available to small business owners. Qualifying and maximizing the deduction isn’t always straightforward.
With thoughtful planning, many business owners can significantly reduce their tax liability while avoiding costly mistakes. Sovereign CPA can help you evaluate your options and develop a tax strategy tailored to your business.
