The Qualified Business Income (QBI) deduction, also known as the Section 199A deduction, is one of the most valuable tax breaks available to freelancers and small business owners. It allows eligible self-employed individuals to deduct up to 20% of their qualified business income, effectively reducing the tax rate on that income by a significant margin. With the deduction's legislative status evolving, 2026 is a critical year to understand how it works and whether you qualify.
What Is the QBI Deduction?
The QBI deduction was introduced by the Tax Cuts and Jobs Act (TCJA) in 2018 to give pass-through business owners a benefit similar to the corporate tax rate reduction that C-corporations received. If you operate as a sole proprietor, single-member LLC, partnership, or S-corporation, your business income passes through to your personal tax return. The QBI deduction lets you subtract up to 20% of that income before calculating your tax, potentially saving you thousands of dollars.
How Much Can You Actually Save?
The math is straightforward. If you earn $100,000 in qualified business income and claim the full 20% deduction, you reduce your taxable income by $20,000. For someone in the 24% marginal tax bracket, that translates to $4,800 in federal tax savings. For a freelancer in the 32% bracket, the savings jump to $6,400. The effective result is that your tax rate on business income drops by roughly 4 to 7 percentage points.
At a 24% marginal rate, the QBI deduction effectively reduces your tax on business income from 24% to about 19.2%, a savings of nearly 20% on the tax itself.
Who Qualifies in 2026?
Eligibility depends on your taxable income, the type of business you operate, and whether you provide a specified service. The rules apply differently based on income thresholds.
Below the Income Threshold
If your total taxable income (from all sources, not just business) falls below the IRS income threshold for your filing status, you qualify for the full 20% deduction regardless of your business type. These thresholds are adjusted annually for inflation — check IRS.gov for the current-year figures (for 2025, the threshold was approximately $197,300 for single filers and $394,600 for married filing jointly). This is the simplest scenario, and the one that applies to most freelancers. Your deduction is the lesser of 20% of your QBI or 20% of your total taxable income minus net capital gains.
Above the Income Threshold
Above the threshold, things get more complex. If you operate a Specified Service Trade or Business (SSTB), which includes fields like consulting, law, accounting, health care, and financial services, the deduction phases out as your income rises above the threshold. If you operate a non-SSTB (such as a construction company, manufacturing business, or retail operation), the deduction may be limited by the greater of 50% of W-2 wages paid or 25% of W-2 wages plus 2.5% of the unadjusted basis of qualified property.
Which Businesses Are SSTBs?
The SSTB classification matters for higher-income freelancers. The following fields are considered specified service trades or businesses under the IRS rules.
- Health care (doctors, dentists, therapists, nurses)
- Law (attorneys, paralegals)
- Accounting (CPAs, bookkeepers, tax preparers)
- Actuarial science
- Performing arts
- Consulting
- Athletics
- Financial services (investment management, financial advising)
- Brokerage services
- Any business where the principal asset is the reputation or skill of its employees or owners
Notably, engineering and architecture were explicitly excluded from the SSTB list, so freelancers in those fields benefit from the deduction even at higher income levels.
How to Calculate Your QBI Deduction
- Determine your net qualified business income (gross business income minus business deductions)
- Calculate 20% of your QBI
- Calculate 20% of your total taxable income minus net capital gains
- Your QBI deduction is the lesser of the two amounts from steps 2 and 3
- If above the income threshold, apply the SSTB limitations or W-2 wage/property tests
Strategies to Maximize Your QBI Deduction
There are several legitimate strategies freelancers can use to maximize the QBI deduction.
- Contribute to retirement accounts (Solo 401k or SEP IRA) to reduce taxable income below SSTB thresholds
- Time large business expenses to reduce QBI in high-income years (be careful about reducing QBI too much, as this also reduces the deduction)
- If married, consider filing status implications on the income threshold
- Keep meticulous records of all business income and deductions using tools like InvoiceFold
- Consult a tax professional if your income is near the phase-out threshold
The 2026 Legislative Landscape
The original TCJA provisions, including the QBI deduction, were set to expire after 2025. Congress has been debating extensions and modifications throughout 2025 and into 2026. As of early 2026, the deduction remains available, though the exact thresholds and rules may have been adjusted. Check IRS.gov or consult a tax professional for the most current information. Regardless of legislative changes, tracking your income accurately with a platform like InvoiceFold ensures you are ready to claim every deduction you're entitled to.
Common QBI Mistakes to Avoid
- Confusing QBI with gross revenue (QBI is net of business deductions)
- Assuming you do not qualify without checking the income thresholds
- Forgetting that the deduction is taken on your personal return, not your business return
- Failing to separate business income from W-2 wages if you have both
- Not consulting a tax professional when income is near the SSTB phase-out range
The QBI deduction is one of the most impactful tax provisions for freelancers and small business owners. Even if the rules seem complex, the savings are substantial enough to justify the effort of understanding them. Keep your income and expense records organized, know your income level relative to the thresholds, and consult a professional if your situation is nuanced.
