QBI Deduction 2026: Section 199A Rules After the OBBBA

This article is for educational purposes only and is not tax, legal, or financial advice. Tax rules change periodically. Check current IRS guidance or consult a qualified tax professional before filing.

Quick Answer: The 2026 QBI Deduction

The Section 199A qualified business income (QBI) deduction is still 20% of qualified pass-through income for 2026, and it is now permanent. The One Big Beautiful Bill Act (P.L. 119-21), signed July 4, 2025, removed the 2025 sunset, widened the phase-in ranges, and added a new $400 minimum deduction for filers with at least $1,000 of active QBI.

The 2026 full-deduction thresholds are $201,750 for single and head-of-household filers and $403,500 for married filing jointly. Above those points, the W-2 wage and UBIA limits kick in, and specified service trades or businesses (SSTBs) start to phase out.

Key Takeaways

Rate stayed at 20%. The House-passed 23% figure did not survive into the enacted bill.
Now permanent. The deduction no longer expires at the end of 2025. Owners can plan past one tax year for the first time since 2017.
2026 thresholds: $201,750 single and HoH, $403,500 MFJ for the full deduction; $276,750 and $553,500 are the upper phase-out limits.
Wider phase-in: The phase-in range is now $75,000 for non-joint filers (up from $50,000) and $150,000 for joint filers (up from $100,000).
$400 floor: If you have at least $1,000 of QBI from an active business where you materially participate, you get at least $400.
Standard or itemized: The QBI deduction stacks on top of either. You do not have to itemize.

What the QBI Deduction Is in 2026 (and Why It Matters)

The QBI deduction lets owners of pass-through businesses subtract up to 20% of their qualified business income from federal taxable income. Pass-through means the business itself does not pay corporate income tax. The profit “passes through” to the owner’s personal return instead: sole proprietorships, single-member LLCs, partnerships, multi-member LLCs taxed as partnerships, and S-corps.

This one deduction is among the biggest tax breaks self-employed people and small business owners get. For a freelancer with $80,000 of net Schedule C income, it can knock $16,000 off taxable income and save several thousand dollars in federal tax. For an S-corp owner with $300,000 of pass-through profit, the math gets even bigger.

What changed under the OBBBA

Three things shifted for 2026:

Permanence. Section 199A was originally a TCJA provision set to sunset after December 31, 2025. The OBBBA repealed that sunset entirely.
Wider phase-in. Above the income threshold, the W-2 wage and UBIA limits used to bite over a $50,000 range (single) or $100,000 range (joint). Those ranges are now $75,000 and $150,000.
$400 floor. A new minimum deduction guarantees at least $400 for any active business owner with $1,000 or more of QBI.

What did not change: the 20% rate, the SSTB list, the basic W-2 wage and UBIA tests, and the overall cap at 20% of taxable income minus net capital gains.

Who qualifies

You qualify if you have income from a qualified U.S. trade or business that is not a C-corp. Common eligible sources:

Net profit from a Schedule C sole proprietorship or single-member LLC
Pass-through profit on a K-1 from a partnership or S-corp (not including reasonable W-2 wages paid to S-corp owners)
Net rental income from a real estate enterprise that rises to the level of a trade or business
Qualified REIT dividends and qualified publicly traded partnership (PTP) income, reported on a separate REIT/PTP component

Capital gains, interest income, dividends from regular C-corps, and wages from a W-2 job are not QBI.

2026 Income Thresholds, Phase-In Ranges, and the New $400 Minimum

The biggest practical question is “where does my taxable income fall?” Three zones determine how the deduction works.

Zone 1: Below the threshold (simple deduction)

If your taxable income (before the QBI deduction) sits at or below the threshold, you get a clean 20% of QBI, capped by 20% of taxable income minus net capital gains. No W-2 wage test. No SSTB carve-out. You file the short Form 8995.

2026 QBI thresholds and upper phase-out limits
Filing Status	Full Deduction Up To	Phase-In Range	Upper Limit
Single / HoH	$201,750	$75,000	$276,750
Married Filing Jointly	$403,500	$150,000	$553,500
Married Filing Separately	$201,750	$75,000	$276,750

Zone 2: Inside the phase-in range (limits start to bite)

Between the threshold and the upper limit, the W-2 wage and UBIA limits phase in proportionally. SSTB owners also start losing their deduction on a sliding scale. The phase-in zones are now wider:

Non-joint filers: $75,000 wide (was $50,000)
Joint filers: $150,000 wide (was $100,000)

That wider window is friendlier to borderline filers. A single SSTB owner at $240,000 of taxable income still gets roughly half the deduction in 2026, whereas under the old $50,000 phase-in the same person would have been close to zero.

Zone 3: Above the upper limit (full limits apply)

Above $276,750 (single/HoH) or $553,500 (MFJ), two hard rules apply:

W-2 wage / UBIA limit. The deduction is capped at the greater of (a) 50% of W-2 wages paid by the business, or (b) 25% of W-2 wages plus 2.5% of the unadjusted basis immediately after acquisition (UBIA) of qualified property.
SSTB lockout. If the business is an SSTB, the deduction drops to zero.

The new $400 minimum deduction

The OBBBA added a backstop for small operators. If you have at least $1,000 of QBI from an active trade or business in which you materially participate, you get at least $400, even if 20% of QBI would have produced less. Both the $1,000 and $400 figures are inflation-adjusted after 2026.

This matters most for thin-margin side gigs: an Etsy seller, a weekend ride-share driver, a part-time consultant. A solo proprietor with $1,500 of net QBI would normally get $300 (20% of $1,500). The $400 floor bumps that up. Material participation tracks the same rules used for passive activity loss tests, so a true side hustle counts, but a purely passive investment usually does not.

How to Calculate Your QBI Deduction (with Examples)

The basic formula is:

QBI Deduction = lesser of (a) 20% of QBI, or (b) 20% of (Taxable Income − Net Capital Gains)

Above the threshold you add the W-2 wage and UBIA limits. Here is how each archetype looks in 2026.

Example 1: Schedule C freelancer (below threshold)

Maya is single, has $80,000 of net Schedule C profit, and no other income. After the deductible half of self-employment tax (about $5,652) and the standard deduction ($16,100), her taxable income before QBI is roughly $58,250. Her QBI is $74,348 (Schedule C profit minus the SE tax adjustment).

20% of QBI: $14,870
20% of taxable income: $11,650
Deduction: $11,650 (the smaller of the two)

Maya is below the $201,750 threshold, so no SSTB or W-2 wage worries. She files Form 8995.

Example 2: S-corp owner-employee (in the phase-in)

Ben and Priya are married filing jointly. Ben’s S-corp pays him $90,000 of reasonable W-2 wages and generates $260,000 of pass-through profit on his K-1. The S-corp also paid $90,000 of W-2 wages total (just to Ben). Their taxable income before QBI is $450,000, which sits $46,500 into the $150,000 MFJ phase-in.

QBI is the $260,000 K-1 profit (not Ben’s W-2 wages). 20% of QBI would be $52,000. But because they are above the threshold, the W-2 wage limit phases in:

50% of W-2 wages: $45,000
The W-2 wage limit is partially applied because they are only 31% into the phase-in zone ($46,500 / $150,000).
Their final deduction lands between the full $52,000 and the W-2 cap of $45,000, roughly $49,800 after the proportional phase-in math on Form 8995-A.

This is where running real numbers matters. The wider OBBBA phase-in means owners in this zone keep more of the deduction than they would have in 2025.

Example 3: SSTB professional (above upper limit)

Dr. Chen, a single dentist, has $400,000 of taxable income from her PLLC. Dentistry is an SSTB (health field). She is above the $276,750 upper limit for single filers.

Result: $0 QBI deduction. The SSTB phase-out completes at the upper limit, and the deduction disappears.

If Dr. Chen made a $30,000 traditional 401(k) contribution and timed some receivables, she could possibly drop taxable income into the phase-in zone and reclaim a partial deduction. That kind of bracket and threshold management is the most common SSTB planning move.

Example 4: The $400 floor scenario

Jordan drives weekends and clears $1,800 of net Schedule C profit. After the SE tax adjustment, QBI is about $1,673. 20% of that is $335. Because Jordan has at least $1,000 of QBI from an active business and materially participates, the $400 floor applies. The deduction is $400, not $335.

SSTB Rules: Who Is Locked Out (and Who Is Not)

An SSTB is a “specified service trade or business,” and the SSTB designation matters only once taxable income exceeds the threshold. Below the threshold, SSTB status is irrelevant: every owner gets the full deduction.

SSTB fields

The IRS lists these fields as SSTBs:

Health (doctors, dentists, nurses, therapists, pharmacists)
Law
Accounting
Actuarial science
Performing arts
Consulting
Athletics
Financial services
Investing and investment management
Dealing in securities, partnership interests, or commodities
Any trade where the principal asset is the reputation or skill of one or more employees or owners

Two notable exclusions: engineering and architecture are not SSTBs, even though they are professional services. Owners in those fields keep the deduction above the threshold as long as they meet the W-2 wage and UBIA tests.

”Reputation or skill” is narrow

The reputation or skill catch-all sounds broad, but the regulations read it narrowly. It mostly covers people who earn licensing fees, endorsement income, or appearance fees from their personal brand. A skilled craftsperson who runs a custom cabinet shop is not an SSTB just because their reputation drives sales.

How the wider phase-in helps SSTB owners

Under the old $50,000 (single) and $100,000 (joint) phase-in ranges, SSTB owners who crossed the threshold lost their deduction quickly. The new $75,000 and $150,000 windows mean a doctor or lawyer whose taxable income drifts a bit over the threshold still keeps a meaningful chunk of the deduction.

Form 8995 vs. Form 8995-A: Which to File

One-paragraph decision tree: file Form 8995 if your taxable income is at or below the 2026 threshold ($201,750 single/HoH or $403,500 MFJ) and you do not own an SSTB. Otherwise, file Form 8995-A. Form 8995-A is also required for any aggregation election, any W-2 wage or UBIA limit calculation, or any patron of an agricultural or horticultural cooperative.

Form 8995 (simplified)

Two pages. You list your QBI per business, add qualified REIT dividends and PTP income on line 6, and apply the 20% rate. There are no SSTB schedules, no W-2 wage worksheets, and no UBIA tracking.

Form 8995-A (full version)

Four schedules:

Schedule A for SSTB phase-in calculations
Schedule B for aggregating multiple businesses under Reg. §1.199A-4
Schedule C for losses and loss carryforwards
Schedule D for special rules for patrons of cooperatives

The most common mistake on 8995-A is forgetting to bring forward prior-year QBI losses, which reduce the current year’s deduction. The second most common is not aggregating businesses that should be aggregated, leaving deduction dollars on the table.

How the QBI Deduction Interacts with the Rest of Your Return

Section 199A does not sit in a vacuum. Three interactions trip up filers most often.

Self-employment tax adjustment comes first

For Schedule C and partnership filers, QBI is reduced by the deductible half of SE tax (and by self-employed retirement contributions and self-employed health insurance) before the 20% rate is applied. A freelancer with $100,000 of net profit does not get $20,000 of QBI deduction; QBI is closer to $92,350, so the deduction is closer to $18,470.

The 20% of taxable income cap

The deduction can never exceed 20% of (taxable income minus net capital gains). For most filers this is not binding, but it matters for retirees or investors with large capital gains who also have a small business. If most of your income is long-term capital gains, your QBI deduction can be sharply limited.

Works with the standard deduction

The QBI deduction is taken on Form 1040 line 13, after the standard or itemized deduction. You do not have to itemize. About 90% of filers use the standard deduction; QBI works just the same for them.

SALT cap and other interactions

The 2026 SALT cap is now $40,400, so itemizers in high-tax states sometimes drop their taxable income enough to fall into a more favorable QBI zone. State income tax planning, retirement contributions, and SE tax interplay are exactly the kind of moves a whole-return view catches. Tax47 models all of this on the same page: drop in a 1099 or Schedule C and the QBI deduction recalculates live, alongside SE tax, the SALT deduction, and the Child Tax Credit. If you want to test scenarios first, the tools page has the calculator collection.

2026 Planning Moves to Maximize Your Deduction

Most QBI planning comes down to one idea: control where your taxable income lands relative to the threshold and the upper limit. A few moves that work in 2026:

S-corp reasonable compensation tuning. Lower owner W-2 wages mean more pass-through profit (more QBI), but the W-2 wage limit above the threshold needs enough wages to support the deduction. There is a sweet spot, and it shifts year to year.
Retirement contributions. A solo 401(k) or SEP-IRA contribution lowers taxable income, which can drop you below the threshold or further into the phase-in zone. Self-employed health insurance and HSA contributions do the same.
Aggregation elections. Under Reg. §1.199A-4, you can aggregate commonly controlled businesses into a single QBI calculation. This is huge for landlords with multiple rental entities and for serial entrepreneurs whose individual businesses fail the W-2 wage test alone.
Timing of receivables and expenses. Cash-basis filers can sometimes shift income or accelerate deductible expenses across year-end to land in a friendlier QBI zone.
Watch the $400 floor for new side gigs. If you started a side business and crossed the $1,000 QBI mark, file Form 8995 to claim the floor even if the math otherwise produces a tiny deduction.

For state income tax planning that interacts with QBI, the blog covers filing-status and bracket strategy in more depth. The Tax47 app on iOS and Android handles the live recalculation if you would rather see the numbers update as you enter income.

What Did Not Change

For filers reading older articles or House-passed coverage from spring 2025:

The rate is still 20%, not 23%.
The SSTB list is unchanged. Engineering and architecture are still excluded from SSTB treatment.
The W-2 wage / UBIA test is the same: greater of 50% of W-2 wages or 25% of W-2 wages plus 2.5% of UBIA.
The REIT/PTP component is still computed separately and is not subject to the W-2 wage or UBIA limit.
The 20% of taxable income cap (net of capital gains) still applies.

Frequently Asked Questions

What is the QBI deduction for 2026?

The QBI deduction is a 20% pass-through deduction under Section 199A, made permanent by the One Big Beautiful Bill Act. It applies to most sole proprietorships, partnerships, S-corps, and qualifying REIT and PTP income.

What are the 2026 income thresholds for the QBI deduction?

The full deduction is available below $201,750 of taxable income for single and head of household filers, and below $403,500 for married filing jointly. The phase-out completes at $276,750 single and $553,500 joint.

Who qualifies for the $400 minimum QBI deduction in 2026?

Any taxpayer with at least $1,000 of QBI from an active trade or business in which they materially participate. The $400 floor and the $1,000 threshold are both inflation-adjusted after 2026.

Is the QBI deduction still 20% in 2026, or did it go to 23%?

Still 20%. The 23% figure was in the House-passed version but was not in the final enacted OBBBA (P.L. 119-21) signed on July 4, 2025.

What is an SSTB and how does it affect the QBI deduction?

A specified service trade or business is a field like health, law, accounting, consulting, or financial services. SSTB owners lose the deduction entirely once taxable income exceeds the upper phase-out limit.

Do I use Form 8995 or Form 8995-A?

Use Form 8995 if your taxable income is below the threshold and you have no SSTB issues. Use Form 8995-A if you are above the threshold, own an SSTB, or need the W-2 wage and UBIA limit.

Can I take the QBI deduction if I use the standard deduction?

Yes. The QBI deduction is taken in addition to either the standard or itemized deduction. It does not require you to itemize.

Does S-corp owner-employee W-2 income count as QBI?

No. Reasonable compensation paid to an S-corp owner is excluded from QBI, but the remaining pass-through profit on the K-1 qualifies.
