If you file a Schedule C, receive 1099-NEC forms, or own part of an S corporation or partnership, there is a deduction sitting on your return that most people either miss or misunderstand. Section 199A, better known as the qualified business income (QBI) deduction, lets you subtract up to 20% of your business profit from your taxable income before the tax rates are even applied. No cash outlay, no receipts, no election form. It is simply a line on your 1040.
It is also one of the most misread provisions in the code. The 20% is not 20% of your revenue, it is not a tax credit, and it does not reduce your self-employment tax by a single dollar. Below is exactly how it works for the 2026 tax year, with the current IRS thresholds and a full worked example.
What the QBI deduction actually is
Section 199A gives owners of pass-through businesses a deduction of up to 20% of their qualified business income. It exists because the 2017 tax law cut the C corporation rate to 21% and Congress wanted to give sole proprietors, partners and S corporation shareholders something comparable. The One Big Beautiful Bill Act, signed in July 2025, made the deduction permanent. It was originally due to expire after 2025, so the sunset you may have read about no longer applies.
Three things it is not:
- Not a business expense. It does not reduce your net profit on Schedule C, so it does not reduce your self-employment tax. A freelancer paying 15.3% SE tax pays it on the full profit regardless.
- Not an itemized deduction. You take it after the standard deduction or itemized deductions, and you get it either way. Taking the standard deduction costs you nothing here.
- Not a credit. A $20,000 QBI deduction in the 22% bracket is worth about $4,400, not $20,000.
The IRS overview is on the Qualified Business Income Deduction page.
Who qualifies
You qualify if you have income from a qualified trade or business operated as a sole proprietorship (Schedule C), a single-member LLC, a partnership or multi-member LLC (Schedule K-1), an S corporation (Schedule K-1), or certain rental activities that rise to the level of a trade or business. Qualified REIT dividends and publicly traded partnership income also generate a separate 20% component.
You do not qualify on income earned as a W-2 employee, or on income earned inside a C corporation. If you are a freelancer who was reclassified as an employee, that income is gone for QBI purposes. If you run an S corporation, the salary you pay yourself is W-2 wages and is excluded from QBI, while the remaining profit that passes through on the K-1 is included. That trade-off matters and is covered below.
What counts as qualified business income
QBI is the net amount of income, gain, deduction and loss from your US trade or business. Start with your Schedule C net profit or your K-1 ordinary business income, then subtract the business-related deductions that appear on the front of your 1040. Per the Form 8995-A instructions, QBI is reduced by:
- The deductible half of your self-employment tax
- Your self-employed health insurance deduction
- Contributions to a SEP IRA, SIMPLE IRA or solo 401(k) (the employer side)
- Unreimbursed partnership expenses
QBI excludes capital gains and losses, interest income not allocable to the business, wage income, reasonable compensation paid to you by your own S corporation, guaranteed payments to partners, and most foreign income. This is why a freelancer with $130,000 of Schedule C profit does not have $130,000 of QBI: after the SE tax adjustment it is closer to $120,800.
The 2026 income thresholds
Everything about Section 199A hinges on your taxable income before the QBI deduction. Not revenue, not profit, not AGI. Below the threshold the rules are simple and generous. Above it, two limits kick in. The figures below come from IRS Rev. Proc. 2025-32 (2026) and Rev. Proc. 2024-40 (2025).
| Filing status | 2025 threshold | 2025 top of range | 2026 threshold | 2026 top of range | 2026 phase-in width |
|---|---|---|---|---|---|
| Married filing jointly | $394,600 | $494,600 | $403,500 | $553,500 | $150,000 |
| Single / head of household | $197,300 | $247,300 | $201,750 | $276,750 | $75,000 |
| Married filing separately | $197,300 | $247,300 | $201,775 | $276,775 | $75,000 |
Note the change in the phase-in width. For 2025 the range was $50,000 (single) and $100,000 (joint). For 2026 it widens to $75,000 and $150,000. That is a genuine improvement: the limits now bite more gradually, so a consultant at $230,000 of taxable income keeps more of the deduction in 2026 than the same consultant would have kept in 2025.
Below the threshold: the easy case
If your taxable income before the QBI deduction is at or under $201,750 (single) or $403,500 (joint) for 2026, none of the complicated machinery applies. It does not matter whether you are a doctor, a consultant, a plumber or a coder. It does not matter whether you have employees or equipment. Your deduction is simply:
The lesser of (a) 20% of your QBI, or (b) 20% of your taxable income minus net capital gain.
That second limb is the one people forget, and for a typical freelancer with no other income it is usually the binding one, because the standard deduction pushes taxable income below QBI. You file the one-page Form 8995 and move on.
New for 2026: Section 70105 of the OBBBA added a minimum deduction of $400 for any taxpayer with at least $1,000 of QBI from one or more active trades or businesses in which they materially participate. Both figures are inflation-adjusted after 2026. It is small, but it means a side business with modest profit still produces a floor deduction.
The SSTB phase-out: why consultants lose it
A specified service trade or business (SSTB) is a business in the fields of health, law, accounting, actuarial science, performing arts, consulting, athletics, financial services, brokerage services, investing and investment management, trading, dealing in securities, or any business whose principal asset is the reputation or skill of one or more of its owners or employees. Engineering and architecture were deliberately carved out and are not SSTBs.
If you run an SSTB and your taxable income exceeds the threshold, the deduction phases out entirely over the range. The mechanism is an applicable percentage, computed on Schedule A of Form 8995-A:
Applicable % = 100% - (taxable income above threshold / phase-in width)
Your QBI, your W-2 wages and your UBIA of qualified property are all multiplied by that percentage before anything else happens. Once you pass $276,750 single or $553,500 joint in 2026, the applicable percentage hits zero and the deduction is gone. A solo consultant with $600,000 of profit gets nothing. A solo plumber with $600,000 of profit still gets something, provided he pays wages or owns property (see the next section).
Whether your business is an SSTB is the single highest-stakes classification on the return. Freelance software development, copywriting, graphic design, product photography and most creative services are generally not consulting and not SSTBs. Advising clients on strategy, on the other hand, usually is.
The W-2 wage and UBIA limit for everyone else
If you are not an SSTB but your taxable income is above the threshold, a different cap applies. Your deduction for each business cannot exceed the greater of:
- 50% of the W-2 wages paid by that business, or
- 25% of W-2 wages plus 2.5% of the UBIA (unadjusted basis immediately after acquisition) of qualified depreciable property still within its recovery period
A sole proprietor pays no W-2 wages to himself, so a high-earning solo freelancer above the threshold with no employees and no equipment has a wage limit of $0 and, once fully phased in, a deduction of $0. This is exactly why profitable non-SSTB freelancers with taxable income above the threshold often elect S corporation status: paying yourself a reasonable W-2 salary creates the wage base the limit needs. The catch is that the salary itself is excluded from QBI, so there is an optimum, not a maximum. Between the threshold and the top of the range the wage limit is phased in rather than applied in full, using the same percentage (Part III of Form 8995-A).
Worked example: a freelance developer with $150,000 of 1099 income
Maya is single, files as a sole proprietor, and works as a freelance backend developer (not an SSTB). Tax year 2026, no other income, no itemized deductions, no retirement contributions.
| Step | Amount |
|---|---|
| Gross 1099-NEC income | $150,000 |
| Less business expenses | ($20,000) |
| Schedule C net profit | $130,000 |
| Net earnings from self-employment ($130,000 x 92.35%) | $120,055 |
| Self-employment tax at 15.3% | $18,368 |
| Deductible half of SE tax | ($9,184) |
| Adjusted gross income | $120,816 |
| Less 2026 standard deduction (single) | ($16,100) |
| Taxable income before QBI deduction | $104,716 |
| QBI ($130,000 less half SE tax) | $120,816 |
| 20% of QBI | $24,163 |
| 20% of taxable income (no capital gain) | $20,943 |
| QBI deduction (the lesser) | $20,943 |
| Final taxable income | $83,773 |
Maya is well under the $201,750 threshold, so no SSTB test and no wage limit. Notice that the 20%-of-taxable-income cap is what binds, not 20% of QBI. That is normal for a solo freelancer.
Now the money. Using the 2026 single brackets in Rev. Proc. 2025-32 (10% to $12,400, 12% to $50,400, then 22% to $105,700):
- Income tax on $104,716 (no QBI deduction): $5,800 + 22% x $54,316 = $17,750
- Income tax on $83,773 (with QBI deduction): $5,800 + 22% x $33,373 = $13,142
- Cash saved: $4,607
That is 22% of the $20,943 deduction, her marginal rate. Her self-employment tax stays at $18,368 either way, so her total federal bill lands at $31,510 rather than $36,118. You can run your own figures through the QBI deduction calculator, or model the whole Schedule C picture including SE tax with the 1099 tax calculator.
Worked example: an SSTB consultant inside the phase-in range
David is a single management consultant (an SSTB) with $240,000 of QBI, no employees, no qualified property, and taxable income before the QBI deduction of $239,250 for 2026.
- Excess over threshold: $239,250 minus $201,750 = $37,500
- Phase-in percentage: $37,500 / $75,000 = 50%. Applicable percentage: 50%
- Includible QBI: $240,000 x 50% = $120,000. Includible W-2 wages: $0
- Tentative 20% deduction: $24,000. Wage limit: 50% of $0 = $0
- Phased-in reduction: ($24,000 minus $0) x 50% = $12,000
- QBI deduction: $24,000 minus $12,000 = $12,000
At his 32% marginal rate (the 2026 single 32% bracket runs from $201,775 to $256,225) that is worth about $3,840. Had David's taxable income reached $276,750, the deduction would have been exactly zero. Had he been an engineer instead of a consultant with the same numbers, the SSTB haircut would not apply, but the $0 wage limit still would, which is precisely the case for S corporation planning.
Filing it, and four moves that protect it
Use Form 8995 if your taxable income before the deduction is at or below the threshold and you are not a co-op patron. Use Form 8995-A (plus Schedule A for SSTBs) if you are above it. The deduction lands on Form 1040 line 13. There is no election and no statement to attach in the simple case, but you must still have a genuine trade or business.
Four things that actually move the number:
- Fund a solo 401(k) or SEP. This is double-edged. It cuts taxable income (helpful if you are in the phase-out range) but it also cuts QBI, so you give up 20 cents of deduction per dollar contributed. Above the threshold it is usually a clear win, below it, less so.
- Watch the threshold like a hawk. If you are an SSTB owner at $215,000 of taxable income, every extra dollar of deduction before year end (retirement contributions, HSA, deferring a December invoice) is worth more than its face value, because it also restores QBI deduction you had lost.
- Consider S corporation status if you are a non-SSTB above the threshold. The W-2 wage limit needs wages to work with, and a sole proprietor has none.
- Separate SSTB and non-SSTB activities. If you consult and also sell a software product, keep the books, contracts and bank accounts genuinely separate so the non-SSTB half survives.
The 2026 return is due 15 April 2027, but the deduction affects your quarterly estimated payments right now, so it is worth getting the number right in April, June, September and January rather than discovering it next spring.
