QBI Deduction 2026: What OBBBA Means for Small Business Owners

The Qualified Business Income (QBI) deduction is one of the most powerful tax benefits for small business owners, self-employed individuals, and partners in pass-through entities. Available since the Tax Cuts and Jobs Act (TCJA) of 2017, the QBI deduction allows eligible business owners to deduct up to 20% of their qualified business income from their taxable income. The OBBBA of 2025 extended this provision indefinitely and made targeted modifications. For a small business owner earning $100,000 in qualified business income, this deduction can reduce their taxable income by $20,000—saving approximately $4,400 at the 22% federal tax bracket. Here's the complete guide to understanding, calculating, and maximizing your QBI deduction in 2026.

What is the QBI Deduction?

The Qualified Business Income (QBI) deduction allows self-employed individuals, sole proprietors, partners, S-corp owners, and LLC members to deduct up to 20% of their business income from their federal income taxes. It is NOT a business expense deduction—it's a personal income tax deduction that applies after you've calculated your net business income.

The formula is simple:

• Net qualified business income (QBI) × 20% = QBI deduction
• You can deduct this amount on your Form 1040, reducing your taxable income

Key Clarification

The QBI deduction is taken at the individual level, NOT at the business level. You compute it on Form 8995 (the simplified form, if you are under the threshold) or Form 8995-A (if you are not), and it lands on Form 1040 as a below-the-line deduction that you get whether or not you itemize. This is important because:

• It doesn't reduce your net profit for self-employment tax purposes — SE tax is calculated before QBI ever enters the picture
• It only reduces your taxable income for federal income tax
• It's separate from any business expense deductions
• It does not reduce your AGI, so it will not help you qualify for anything that phases out on AGI or MAGI

Example:

• You're a freelance consultant earning $80,000 in net business income
• Qualified business income (QBI): $80,000
• QBI deduction: $80,000 × 20% = $16,000
• Federal income tax reduction at 22% bracket: $16,000 × 0.22 = $3,520 in taxes saved

Which Entities Qualify?

The QBI deduction is available to owners of pass-through entities—businesses that don't pay corporate-level income tax. Specifically:

Eligible Entities:

1. Sole Proprietorships — Self-employed individuals reporting business income on Schedule C
2. Partnerships — Including limited partnerships (LPs) and limited liability partnerships (LLPs)
3. S-Corporations — Corporations that elect S-corp status on Form 2553
4. Limited Liability Companies (LLCs) — Taxed as sole proprietorships, partnerships, or S-corps
5. Trusts and Estates — Pass-through entities with business income

NOT Eligible:

• C-Corporations (corporations that pay corporate-level income tax)
• Employees receiving W-2 wages (employees cannot claim QBI)
• Investments (capital gains, dividends, interest income are not QBI)

SSTB Limitations: Specified Service Trades or Businesses

This is where the QBI deduction gets complicated. Certain high-income service businesses face partial or full phase-out of the QBI deduction above certain income thresholds. These are called Specified Service Trades or Businesses (SSTBs).

Note what the threshold is measured on: your taxable income, not your revenue and not your business profit. A consultant with $500,000 of revenue and $190,000 of taxable income after expenses, retirement contributions and the standard deduction is below the line and gets the full 20%. If you are not sure which band you land in, the tax bracket explainer walks the 2026 bands and shows where your taxable income actually falls.

Which Businesses Are SSTBs?

SSTBs are defined in IRC §199A(d)(2), which borrows the list in §1202(e)(3)(A) and then removes engineering and architecture from it. The categories are:

1. Health, Law, Accounting, Consulting Services

   • Medical doctors, dentists, nurses
   • Lawyers and legal services
   • CPAs and accounting firms
   • Consultants (management, financial, HR, etc.)

2. Financial Services

   • Investment advisory services
   • Financial planning
   • Financial management services

3. Athletics, performing arts, and any trade whose principal asset is the reputation or skill of one or more of its owners or employees

   • The reputation-or-skill category is narrower than it sounds. The §199A regulations confine it to endorsement income, licensing your name or likeness, and appearance fees — it is not a catch-all for "my business depends on me being good at it."

4. Brokerage services, and dealing in securities, partnership interests or commodities

   • Note what is not here: engineering and architecture were deliberately carved out of the §199A list, even though they appear in §1202. Engineers and architects are not SSTBs at any income level.

What About Other Service Businesses?

Importantly, many common service businesses are NOT SSTBs and do not face QBI limitations:

• Real estate agents and brokers (real estate sales are not SSTBs)
• Engineers and architects (specifically excluded from the §199A list)
• Hairstylists, beauticians, personal services
• Contractors (construction, plumbing, HVAC, electrical)
• Business owners (retail, hospitality, manufacturing)
• Technology workers (programmers, designers, software developers—generally not SSTBs)
• Insurance agents and brokers

"Consulting" is the genuinely grey one, because it turns on what you are paid for. Advice and counsel is consulting and is an SSTB; being paid to build or operate something generally is not, even if advice is bundled with it. If a large share of your revenue sits on that line, this is the question to take to a CPA — it is worth more than any other planning move in this article.

Phase-Out Rules for High Income

Two different restrictions switch on above the threshold, and confusing them is the most common QBI mistake:

2026 thresholds (taxable income):

• Single and head of household: $201,750
• Married filing jointly: $403,500
• Married filing separately: $201,775

The phase-in range above the threshold — widened by OBBBA from $50,000/$100,000 to $75,000 single / $150,000 joint:

• Single: $201,750 to $276,750
• MFJ: $403,500 to $553,500

Below the threshold, everyone gets the full 20%. SSTB status is irrelevant, W-2 wages are irrelevant, property basis is irrelevant. A doctor with $190,000 of taxable income gets exactly what a plumber with $190,000 gets.

Above the top of the range, the two restrictions apply in full and they are not the same restriction:

Inside the range, both restrictions phase in on a straight line based on how far into the range you are. At the halfway point a single filer is subject to half the wage cap and, if an SSTB, may count only half the QBI.

SSTB Example: The Cliff Is Real

Scenario: You own an accounting firm (an SSTB), filing single:

• Taxable income: $400,000
• QBI: $350,000
• W-2 wages paid to employees: $80,000

Calculation:

• $400,000 is well above $276,750, the top of the single phase-in range
• QBI deduction: $0. Not reduced — gone
• The $80,000 of W-2 wages changes nothing. Hiring more people would change nothing. Once an SSTB clears the top of the range there is no QBI left for a wage cap to limit

The only lever an SSTB owner has is getting taxable income back down into or below the range: a defined benefit or cash balance plan, maximising the 401(k) (the 2026 §415(c) ceiling on total additions is $72,000), deferring December billing to January, or a charitable bunching year.

Non-SSTB Example: The Wage Cap

Scenario: Same numbers, but you own a construction company, filing single:

• Taxable income: $400,000
• QBI: $350,000
• W-2 wages paid to employees: $80,000
• No depreciable property, for simplicity

Calculation:

• Not an SSTB, so no cliff — but above $276,750 the wage/property cap applies in full
• 20% of QBI: $350,000 × 0.20 = $70,000
• 50% of W-2 wages: $40,000
• Alternative test: 25% of wages ($20,000) + 2.5% of unadjusted basis ($0) = $20,000. The greater of the two is $40,000
• QBI deduction: $40,000 — the lesser of $70,000 and $40,000
• Tax saved at the 35% marginal rate: $14,000

Same taxable income, same QBI, same payroll — $40,000 for the contractor and $0 for the accountant. That gap is the whole point of the SSTB rules, and it is why the first question in any QBI conversation is whether you are one.

2026 QBI Deduction Rules Under OBBBA

OBBBA made several key changes to QBI rules for 2026 and beyond:

1. The deduction is permanent

§199A was set to expire after 31 December 2025 under the TCJA sunset. OBBBA §70105 made it permanent. There is no expiry date to plan around any more, which matters most for decisions with long horizons — an entity election, a payroll build-out, a partner buy-in.

This is also the single most common piece of stale advice still circulating: any article telling you to accelerate income into 2025 "before QBI expires", or that the TCJA rates revert after 2025, is describing a law that did not happen. OBBBA made the 10/12/22/24/32/35/37 brackets permanent too.

2. The phase-in range doubled

The band between "full deduction" and "fully limited" widened from $50,000/$100,000 to $75,000 single / $150,000 joint. For an SSTB owner this is a real reprieve: the point at which the deduction hits zero moved up by $25,000 for single filers and $50,000 for joint filers, and the phase-out is now gentler for everyone inside the band.

3. A new $400 minimum deduction

Starting in 2026, a taxpayer with at least $1,000 of QBI from an active trade or business in which they materially participate gets a deduction of at least $400. It is indexed going forward. This is small in dollars but meaningful in reach: it puts a floor under side-business and gig income that would otherwise have generated a trivial deduction, and it is the one genuinely new number to check on this year's return.

4. No change to the 20% rate

The 20% deduction percentage is unchanged. Proposals to raise it to 23% did not survive into the final bill.

5. The thresholds indexed as usual

For 2026 the taxable income thresholds are $201,750 single and head of household, $403,500 married filing jointly, and $201,775 married filing separately (Rev. Proc. 2025-32).

Strategies to Maximize Your QBI Deduction

Strategy 1: Ensure You Qualify

First, verify that your business genuinely qualifies for the QBI deduction:

• Are you a pass-through entity (sole proprietor, partnership, S-corp, LLC)?
• Is your taxable income below $201,750 single / $403,500 joint — or, if it is above, are you not an SSTB?
• Do you have documented net business income on your tax return?

If you answer "yes" to all three, you qualify for the full 20% QBI deduction.

Strategy 2: Increase W-2 Wages — for NON-SSTB owners above the threshold

This is the strategy most often aimed at the wrong taxpayer. Paying W-2 wages raises the cap on your deduction, which only helps if you have a deduction left to cap. An SSTB owner above $276,750 single / $553,500 joint has none, so payroll does nothing for them. A non-SSTB owner in the same position gets a dollar of extra deduction for every two dollars of extra wages:

Example impact (non-SSTB, taxable income above the range):

• $300,000 QBI, $0 W-2 wages → wage cap of $0 → $0 QBI deduction
• $300,000 QBI, $100,000 W-2 wages → cap of 50% × $100,000 = $50,000 deduction
• $300,000 QBI, $120,000 W-2 wages → cap of $60,000, which is now the binding constraint against 20% of QBI ($60,000) — you have reached the maximum and further wages buy nothing

Two cautions. Wages cost you payroll tax and the wages themselves, so this only makes sense for people you were going to hire anyway or pay more anyway — never hire to buy a deduction worth half the wage, and check that the business can actually carry the payroll before you add it; the business liquidity calculator turns your cash and monthly obligations into a runway figure. And if you own property, run the alternative test too: 25% of wages plus 2.5% of the unadjusted basis of qualified property can beat the 50% test outright for capital-heavy businesses like rentals, manufacturing or trucking.

Strategy 2b: For SSTB owners, the only lever is taxable income

If you are a doctor, lawyer, accountant, consultant or financial adviser above the range, stop looking at payroll and start looking at the number the threshold is measured on. Anything that drops taxable income back toward $201,750 single or $403,500 joint restores deduction, and each dollar of reduction can be worth far more than its face value because it buys back QBI deduction on the way down:

• A solo 401(k) or SEP, up to the 2026 §415(c) limit of $72,000 of total additions
• A defined benefit or cash balance plan, which can absorb far more than that for an older high earner
• Deferring December invoicing to January in a year you are just over the line
• Bunching two years of charitable giving into one through a donor-advised fund

Strategy 3: Consider an S-Corp Election (Non-SSTB Owners)

If you're not an SSTB and have significant business income, electing S-corp treatment can sometimes save on self-employment tax:

• Sole prop: You pay 15.3% SE tax on all net profit
• S-corp: You pay yourself a reasonable W-2 salary (subject to 15.3% FICA), then can take remaining profit as a distribution (not subject to SE tax)

The trade-off: S-corps require annual tax returns, payroll processing, and compliance.

Example:

• Sole proprietor earning $150,000 net profit: SE tax applies to 92.35% of profit, so $138,525 × 15.3% = ~$21,195. (All of it is below the 2026 Social Security wage base of $184,500, so the full 15.3% applies.)
• S-corp owner earning $150,000: Pays $80,000 W-2 salary ($12,240 FICA) + $70,000 distribution ($0 SE tax) = $12,240 in FICA
• SE tax savings: ~$8,955 annually

The catch is that "reasonable compensation" is a real standard the IRS enforces, and an $80,000 salary on $150,000 of profit is defensible only if it matches what you would pay someone else to do your job. Set it too low and the saving is recharacterised with penalties. Run your own profit through the self-employment tax calculator to see what the sole-proprietor bill actually is before deciding whether the S-corp's payroll, separate return and compliance cost is worth the difference.

There is also a QBI interaction that cuts the other way: the W-2 salary you pay yourself is not QBI, so an S-corp election shrinks the base your 20% is calculated on. In the example above, electing S-corp status moves $80,000 out of QBI, costing $16,000 of deduction. If you are below the threshold, that can wipe out most of the SE tax saving. The election is strongest for non-SSTB owners who are above the threshold, where the salary simultaneously raises the wage cap.

Strategy 4: Deduct Business Expenses First

Before calculating your QBI, ensure you've deducted ALL eligible business expenses. The QBI deduction applies only to net business income (after business expenses), not gross revenue:

Common deductible business expenses:

• Office supplies and equipment
• Home office deduction (if you have a dedicated workspace)
• Professional development and training
• Subscriptions and software (ChatGPT, Adobe, accounting software)
• Vehicle mileage — the 2026 business standard mileage rate is $0.725 per mile for January through June and $0.76 from July onward, so keep the log split by half-year, or use actual expenses
• Business meals at 50%. Entertainment is not deductible at all — TCJA repealed the entertainment deduction in 2018 and OBBBA did not bring it back. A client dinner is a 50% meal; the ballgame tickets you took them to are zero
• Travel and hotel (business travel only)
• Health insurance (self-employed health insurance deduction)
• Home internet and utilities (business percentage)
• Depreciation, and for 2026 §179 expensing of up to $2,560,000 of equipment, with the phase-out beginning at $4,090,000 of purchases

Maximizing business expense deductions before calculating QBI can significantly increase your net QBI (and thus your 20% deduction).

But notice the direction of the trade. Every dollar of business expense removes a dollar of QBI, and with it twenty cents of QBI deduction. A $1,000 expense therefore cuts taxable income by only $800 once the lost deduction is netted out — at a 24% marginal rate it saves $192, not $240. Business deductions are worth 80 cents on the dollar to anyone claiming the full 20%. That is still worth having for money you were going to spend anyway, and still not a reason to buy something you do not need.

Strategy 5: Timing of Income and Expenses

If you're self-employed and have flexibility, consider:

• Accelerating business expenses into the current year (office equipment, vehicle purchase, software licenses)
• Deferring income to the following year if you're close to the SSTB threshold — for a cash-basis business this can be as simple as invoicing on 2 January instead of 20 December
• Bunching income strategically if you can claim a lower tax bracket in one year

The stakes here are larger than the bracket difference suggests. For an SSTB owner sitting a few thousand dollars into the phase-in range, a dollar of deferred income buys back both the tax on that dollar and a fraction of the QBI deduction, so the effective marginal rate inside the range can exceed the headline bracket by a wide margin. Model it before you act — the 2026 tax return estimator will show what your taxable income actually lands at once the standard deduction and above-the-line items are applied, which is the figure the threshold is tested against.

Strategy 6: Charitable Contributions

Charitable giving is an itemized deduction: it lowers taxable income, not AGI, and only to the extent your itemized total beats the 2026 standard deduction of $16,100 single or $32,200 married filing jointly. That matters because the QBI threshold is tested on taxable income, so a gift that clears the standard deduction hurdle can pull an SSTB owner back into the phase-in range. A Donor-Advised Fund lets you bunch two or three years of giving into one, clear the hurdle decisively in that year, and distribute to charities over time.

Calculating Your QBI Deduction: Step-by-Step

Here's how to calculate your QBI deduction for 2026:

Step 1: Determine Your Net Business Income

For sole proprietors: Line 31 of Schedule C (profit or loss) For S-corp/partnership owners: Your pro-rata share of business income from K-1

Step 2: Ensure Income is Qualified Business Income (QBI)

QBI generally includes business profit from pass-through entities but excludes:

• Investment income (capital gains, dividends, interest)
• Reasonable W-2 wages you paid yourself (S-corp owners)
• Reasonable compensation

Sole proprietors: QBI is Schedule C net profit reduced by the deductible half of self-employment tax, the self-employed health insurance deduction, and any self-employed retirement plan contribution attributable to the business. This is the step people skip, and it always shrinks the deduction.

Step 3: Check your taxable income against the threshold

Is your taxable income above $201,750 single / $403,500 MFJ / $201,775 MFS?

• Below: full 20% deduction. SSTB status and W-2 wages are irrelevant. Stop here and use Form 8995
• Inside the phase-in range (up to $276,750 single / $553,500 MFJ): the limits phase in proportionally. Use Form 8995-A
• Above the range and an SSTB: the deduction is $0
• Above the range and not an SSTB: apply the wage/property cap in Step 5

Step 4: Calculate 20% Deduction (Before Limitations)

QBI × 20% = Tentative QBI deduction

Step 5: Apply the Wage/Property Cap (If Applicable)

If you are a non-SSTB above the range:

• Calculate 50% of W-2 wages paid by the business
• Calculate 25% of W-2 wages + 2.5% of the unadjusted basis of qualified property
• Your QBI deduction = Lesser of (20% of QBI) or (Greater of the two calculations above)

Step 6: Apply Taxable Income Limitation

Your QBI deduction cannot exceed 20% of taxable income minus net capital gains (taxable income figured before the QBI deduction). Long-term gains and qualified dividends are stripped out of the base first, which is why a big investment year can shrink a business deduction that has nothing to do with investments.

Deduction = Lesser of (the amount from Step 5) or (20% of taxable income less net capital gains)

Step 7: Check the new $400 floor

If the result is under $400 and you have at least $1,000 of QBI from an active business you materially participate in, you get $400 instead.

Example Calculation

Profile: Freelance consultant, sole proprietor, single, no dependents

2026 Financials:

• Gross revenue: $150,000
• Business expenses: $40,000
• Net profit (Schedule C, line 31): $110,000
• Self-employment tax: $110,000 × 92.35% = $101,585, × 15.3% = $15,542. The deductible half is $7,771
• Adjusted gross income: $110,000 − $7,771 = $102,229
• Standard deduction (single, 2026): $16,100
• Taxable income before the QBI deduction: $86,129

QBI Deduction Calculation:

• QBI: $110,000 net profit − $7,771 (deductible half of SE tax) = $102,229 — not the full $110,000
• 20% of QBI: $102,229 × 0.20 = $20,446
• Taxable income limit: 20% of $86,129 = $17,226
• QBI deduction allowed: $17,226 (the lesser of the two)

Note what did not happen: at $86,129 of taxable income this consultant is nowhere near $201,750, so consulting being an SSTB is completely irrelevant to the answer. Most self-employed people never touch the SSTB rules at all.

Tax Impact:

• Final taxable income: $86,129 − $17,226 = $68,903
• The 2026 single 22% band runs from $50,400 to $105,700, so the deduction comes off at 22%
• Tax saved: $17,226 × 0.22 = $3,790

Key Takeaways

1. The QBI deduction allows up to 20% of business income to be deducted from taxable income, saving thousands annually for many small business owners.

2. OBBBA made the QBI deduction permanent (§70105), eliminating the sunset that was scheduled for the end of 2025. Any advice premised on that sunset — or on the TCJA brackets reverting — is describing a law that did not happen.

3. The threshold is measured on taxable income, not revenue, and for 2026 it is $201,750 single / $403,500 joint. Below it, everyone gets the full 20% and none of the complicated rules apply.

4. Above the threshold, SSTB owners (doctors, lawyers, accountants, consultants, financial advisers) face a cliff, not a cap. Past $276,750 single / $553,500 joint the deduction is $0, and paying W-2 wages does not help. Their only lever is bringing taxable income down.

5. Above the threshold, non-SSTB owners face a cap, not a cliff — the greater of 50% of W-2 wages, or 25% of wages plus 2.5% of qualified property basis. Payroll and property both raise it.

6. New for 2026: the phase-in range widened to $75,000 single / $150,000 joint, and a $400 minimum deduction now applies to anyone with at least $1,000 of active QBI.

7. An S-corp election cuts both ways. It saves self-employment tax but moves your salary out of QBI, shrinking the 20% base. It is strongest for non-SSTB owners above the threshold, where the salary also raises the wage cap.

If you're a self-employed person or small business owner, the first question is always which side of the threshold your taxable income lands on — everything else follows from that. Consult a CPA before restructuring an entity or adding payroll on the strength of this deduction.

FAQ

Q: Is my consulting business an SSTB? A: It depends on what the client is buying. Under the §199A regulations, "consulting" means being paid for advice and counsel; being paid to build, operate, install or supply something is not consulting even when advice comes with it. An IT consultant who configures and maintains systems is generally not an SSTB; a management consultant who writes strategy memos generally is. If services are bundled, the regulations look at whether the consulting element is billed separately or is merely ancillary. This only matters at all if your taxable income exceeds $201,750 single or $403,500 joint — below that, the answer changes nothing.

Q: I'm over the threshold and I'm an SSTB. Is there really nothing I can do? A: Nothing on the wage side, no. But the deduction comes back the moment taxable income falls into the phase-in range, and for an SSTB inside that range the effective return on a dollar of deferred income is unusually high, because each dollar buys back both tax and reinstated QBI. The tools are a cash balance or defined benefit plan, a solo 401(k) or SEP up to the 2026 §415(c) limit of $72,000 in total additions, bunching charitable giving through a donor-advised fund, and shifting billing across the year-end. A married SSTB owner also has $403,500 of room rather than $201,750, which is often the difference on its own.

Q: Do rental properties qualify for QBI? A: Only if the rental activity rises to the level of a trade or business under §162 — a genuinely fact-specific test. The IRS provides a safe harbour in Revenue Procedure 2019-38: 250 or more hours of rental services a year for the enterprise, separate books and records, and contemporaneous time logs. Meet it and you may treat the enterprise as a trade or business for §199A. Miss it and you may still qualify, but you are arguing the general standard rather than resting on the safe harbour. Triple-net leases are specifically excluded from the safe harbour.

Q: I already filed and forgot to claim QBI. Can I fix it? A: Yes. File an amended return on Form 1040-X with Form 8995 or 8995-A attached; the general deadline is three years from the original filing date or two years from when the tax was paid, whichever is later. This is worth checking on any year you were self-employed, because the deduction is easy to miss when it is not the first thing on the return, and on $100,000 of QBI it is roughly $4,400 at the 22% rate.
