How Does the QBI Phase-Out Work? (w/Examples) + FAQs

This article reflects federal rules as of June 2026 and covers tax years 2025 and 2026. Tax law changes — confirm current figures with IRS.gov before you file. This guide is educational and is not a substitute for advice from a licensed CPA or tax attorney for your specific situation.

Quick Answer

The QBI phase-out gradually shrinks your 20% deduction once taxable income passes a yearly threshold. For 2025, the phase-out range runs $197,300–$247,300 (single) and $394,600–$494,600 (joint). For 2026, the range widens to $75,000 (single) and $150,000 (joint) above the threshold.

What the QBI Phase-Out Actually Does

The Qualified Business Income (QBI) deduction lets owners of pass-through businesses deduct up to 20% of their business income, under Section 199A of the tax code. The phase-out is the income zone where two extra limits start to bite and slowly reduce — or fully erase — that deduction.

Below the threshold, the math is simple and you get the full 20%. Above the threshold, the IRS applies wage and property tests, and if you run a “specified service” business, your deduction can disappear entirely. The phase-out is the sliding ramp between “full deduction” and “limited or zero deduction,” and exactly how it works depends on what kind of business you own.

This matters because the deduction is large. According to the Tax Foundation, the Section 199A deduction is one of the most-claimed business tax breaks in the country, used on tens of millions of returns each year. Landing in the phase-out zone can cost a high earner thousands of dollars, so knowing the mechanics is real money in your pocket.

The Two Phase-Outs: SSTB vs. Wage/Property

There is no single “QBI phase-out.” There are two separate phase-outs that share the same income trigger, and which one hits you depends on your business type.

The first is the SSTB phase-out. A Specified Service Trade or Business is one where the main asset is the skill or reputation of its people. The IRS lists these fields: health, law, accounting, actuarial science, performing arts, consulting, athletics, financial services, brokerage, and investing. If you own an SSTB, your entire deduction phases out across the range — and once you pass the top, it hits zero.

The second is the W-2 wage and qualified property limit. This applies to every high-income business, SSTB or not. Above the threshold, your deduction cannot exceed the greater of (a) 50% of the W-2 wages your business paid, or (b) 25% of W-2 wages plus 2.5% of the unadjusted basis of qualified property (think buildings and equipment). The phase-out is the zone where this cap fades in from “no limit” to “full limit.”

The consequence of confusing the two is expensive. A consultant who thinks she only faces the wage test may claim a deduction she has already lost to the SSTB rule, triggering an IRS notice and back tax. What you should do: first ask “Am I an SSTB?” then ask “Where does my taxable income fall in the range?” Those two answers decide everything.

The 2025 Thresholds and Phase-Out Ranges

For tax year 2025, the deduction is fully clean below the threshold, fully limited above the top, and partially limited in between. The 2025 numbers are:

Filing Status (2025)	Threshold (full deduction below)	Top of Phase-Out (full limit above)
Single / Head of Household	$197,300	$247,300
Married Filing Jointly	$394,600	$494,600

The phase-out range — the width of the ramp — is $50,000 for single filers and $100,000 for joint filers in 2025. Inside this band, you do not lose the deduction all at once; you lose it in proportion to how far you have climbed into the range. A single filer at $222,300 sits exactly halfway, so half of the limit applies.

The consequence of crossing $247,300 single or $494,600 joint as an SSTB owner is total loss of the deduction on that SSTB income. What you should do: if you are near the top, look at moves that lower taxable income — a larger retirement-plan contribution or a deductible equipment purchase — before December 31, because the deduction is measured on the full calendar year.

The 2026 Thresholds and Wider Ranges

For tax year 2026, the One Big Beautiful Bill Act (OBBBA) made two reader-friendly changes. First, it made the QBI deduction permanent, removing the old expiration that would have ended it after 2025. Second, it widened the phase-out ranges, as confirmed by Landmark CPAs.

Filing Status (2026)	Phase-Out Range Width
Single / Head of Household	$75,000 (up from $50,000)
Married Filing Jointly	$150,000 (up from $100,000)

The base thresholds for 2026 continue to adjust for inflation from the 2025 figures, so confirm the official inflation-adjusted numbers before you file. The practical effect of the wider range is gentler: the deduction now fades over a longer income stretch, so a high earner keeps more of it deeper into the phase-out.

OBBBA also added a new $400 minimum deduction starting in 2026. If you materially participate in an active business and have at least $1,000 of QBI, you are guaranteed at least $400, even if the wage and property limits would otherwise drop you to zero. This figure will adjust for inflation. What you should do: if you are a small active owner with thin wages, this floor is automatic — make sure your preparer applies it.

Which Situation Applies to You?

The right path depends on three facts about your return. Find your row, then read the section it points to.

Taxable income below the threshold (any business): You take the full 20%, no phase-out math. Skip to the “Full Deduction” example and file Form 8995, the simplified version.
Income in the phase-out range, non-SSTB: Only the wage/property limit applies, and it phases in. Read “Worked Example 2” and file Form 8995-A.
Income in the phase-out range, SSTB: Both your QBI and your wages/property are reduced by an “applicable percentage.” Read “Worked Example 3” carefully — this is the hardest case.
Income above the top of the range, SSTB: Your deduction on SSTB income is zero for 2025 and 2026. Confirm only the $400 minimum (2026) does not apply elsewhere.
Income above the top, non-SSTB: Your deduction is fully capped at the wage/property limit — no partial blending.

Worked Example 1 — Full Deduction, No Phase-Out

Meet Daniel Ruiz, a single freelance graphic designer with $80,000 of QBI and $90,000 of taxable income before the QBI deduction in 2025. His income is well under the $197,300 single threshold, so no phase-out applies.

His math is the simple version. Twenty percent of his QBI is 0.20 × $80,000 = $16,000. Twenty percent of his taxable income is 0.20 × $90,000 = $18,000. He takes the smaller number, so Daniel’s deduction is $16,000. He files the short Form 8995 and never touches a wage or property test. This is the clean baseline every other example deviates from.

Worked Example 2 — Non-SSTB in the Phase-Out (Wage Limit)

Meet Karen Webb, a single owner of a small manufacturing LLC (a non-SSTB) in 2025. Her taxable income before QBI is $222,300 — exactly halfway through the $197,300–$247,300 range. Her QBI is $200,000, her business paid $40,000 in W-2 wages, and she has no significant qualified property.

Step one: the unlimited deduction would be 20% × $200,000 = $40,000. Step two: the full wage limit is 50% × $40,000 wages = $20,000. Step three: because she is halfway through the range, only half of the gap between the two amounts is subtracted. The gap is $40,000 − $20,000 = $20,000; half of that is $10,000. Her deduction is $40,000 − $10,000 = $30,000. If Karen sat above $247,300, the full $20,000 cap would apply and she would deduct only $20,000. She files Form 8995-A.

Worked Example 3 — SSTB in the Phase-Out (Double Reduction)

Meet Dr. Priya Shah, a single dentist (health is an SSTB) in 2025 with $222,300 of taxable income before QBI — again, halfway through the range. Her QBI is $200,000 and her practice paid $60,000 in W-2 wages.

For an SSTB inside the range, you first find the applicable percentage: 100% minus the share of the range you have used. Karen is 50% through, so her applicable percentage is 100% − 50% = 50%. Both her QBI and her wages are multiplied by that 50%. Her usable QBI becomes $200,000 × 50% = $100,000, and her usable wages become $60,000 × 50% = $30,000.

Now run the normal limit on the reduced figures. Twenty percent of reduced QBI is 0.20 × $100,000 = $20,000. The wage limit is 50% × $30,000 = $15,000. She takes the smaller, so Dr. Shah’s deduction is $15,000. Had her income topped $247,300, her applicable percentage would be 0% and her deduction would be zero. This double haircut is why SSTB owners feel the phase-out hardest.

Three Common Phase-Out Scenarios

These tables show how a single change in one fact flips the result. Each is a 2025 scenario.

SSTB Owner’s Income Position (2025, single)	Effect on the Deduction
Below $197,300	Full 20% deduction, no SSTB or wage limit
Between $197,300 and $247,300	Partial deduction; QBI and wages cut by applicable percentage
Above $247,300	Deduction is fully eliminated to $0

Non-SSTB Owner’s Income Position (2025, joint)	Effect on the Deduction
Below $394,600	Full 20%, wage/property test ignored
Between $394,600 and $494,600	Wage/property cap phases in proportionally
Above $494,600	Deduction fully capped at wage/property limit

Year-End Planning Move	Result on a Borderline Return
Boost 401(k) or SEP contribution	Lowers taxable income, may pull you back under the threshold
Buy and place equipment in service	Adds qualified property and can raise the wage/property cap

How the Math Is Built: The Applicable Percentage

The engine behind the SSTB phase-out is a single fraction called the applicable percentage. It equals 100% minus a ratio: how far you are into the range, divided by the full range width.

For a single SSTB filer in 2025, the formula is:

[ \text{Applicable \%} = 1 – \frac{\text{Taxable income} – 197{,}300}{50{,}000} ]

So a single SSTB owner at $210,000 has used ($210,000 − $197,300) ÷ $50,000 = 25.4% of the range, leaving an applicable percentage of about 74.6%. That percentage is then applied to both QBI and W-2 wages before the regular limit runs. The non-SSTB wage limit uses the same fraction, but it reduces only the excess over the wage cap rather than the income itself. Misreading which version applies is the single most common phase-out error.

Form 8995-A: The Phase-Out Form

If your taxable income lands in or above the phase-out range, you cannot use the short form — you must file Form 8995-A and attach it to your Form 1040. The form has four parts plus schedules, and each part has a job.

Part I lists each trade or business and asks whether it is an SSTB. Checking this box wrong is fatal — an SSTB marked “no” overstates the deduction and invites an IRS adjustment. Part II applies the SSTB applicable percentage and runs the QBI calculation, including the W-2 wage and 2.5%-of-property tests. Part III combines your QBI component with the 20% REIT/PTP component. Part IV compares that total to 20% of your taxable income and reports the final, smaller number.

The deadline is your regular return due date — April 15, 2026 for tax year 2025, or October 15 with a valid extension. What you should do: keep your payroll records and fixed-asset schedule, because the wage and property figures on this form must be provable if the IRS asks. DIY software handles it, but a phase-out return often justifies a CPA, typically $400–$1,200 depending on complexity.

Mistakes to Avoid

Each of these errors carries a real dollar or compliance cost.

Mislabeling an SSTB as a regular business — overstates the deduction and triggers IRS adjustment plus interest.
Using Form 8995 when income is in the range — the IRS rejects the simplified form above the threshold and may recompute your tax.
Forgetting the wage/property test applies to non-SSTBs too — high earners assume only SSTBs are limited and over-claim.
Measuring income after the QBI deduction instead of before — the threshold uses taxable income before QBI, so the wrong base mis-sizes the phase-out.
Ignoring REIT and PTP income — these get a separate 20% that is not subject to the wage limit, and skipping it leaves money on the table.
Netting business losses incorrectly — a loss in one business reduces QBI from another, and a net loss carries forward to shrink next year’s deduction.
Overlooking the $400 minimum for 2026 — active small owners with low wages may wrongly report zero.

Do’s and Don’ts

Do confirm whether each business is an SSTB before anything else, because it controls which phase-out applies.
Do measure taxable income before the QBI deduction, since that is the figure the threshold uses.
Do track W-2 wages and qualified property all year, because both feed the cap.
Do consider year-end income moves if you are near the top of the range, because the deduction is measured on the full year.
Do file Form 8995-A whenever you are in or above the range, since the short form is not allowed there.
Don’t assume a state follows the federal deduction — many do not (see below).
Don’t ignore the wage limit just because you are not an SSTB; it still caps you above the threshold.
Don’t forget aggregation rules, because grouping businesses can rescue a deduction limited by low wages.
Don’t guess the applicable percentage; one wrong ratio changes the whole result.
Don’t skip professional help on a borderline SSTB return, where a small error costs thousands.

Pros and Cons of the Phase-Out Structure

Pro: The ramp is gradual, so you don’t lose everything by earning one extra dollar over the threshold.
Pro: OBBBA’s wider 2026 ranges let high earners keep more of the deduction.
Pro: Non-SSTB owners can raise their cap by paying W-2 wages or buying property.
Pro: The new $400 minimum (2026) protects the smallest active owners.
Pro: REIT and PTP income sidesteps the wage limit entirely.
Con: SSTB owners face a double reduction on QBI and wages at once.
Con: The two-limit math is complex and pushes filers onto Form 8995-A.
Con: SSTB income above the top gets zero, a hard cliff for many professionals.
Con: Many states ignore the deduction, so state tax is unaffected.
Con: Borderline planning often requires paid professional help.

Does My State Follow the QBI Deduction?

The QBI deduction is a federal deduction that reduces federal taxable income, not adjusted gross income. Most states that start their tax math from federal AGI — such as California and New York — do not pass the deduction through, so your state tax is computed as if QBI never existed.

A handful of states that begin from federal taxable income may effectively allow it, and the nine states with no income tax — including Texas, Florida, and Washington — make the question moot. What you should do: check your state revenue agency page directly, because conformity genuinely varies and a wrong assumption can mis-state your state return.

What to Do Next

Follow these steps in order before you file.

Decide whether each business is an SSTB, using the IRS field list.
Calculate your taxable income before the QBI deduction and compare it to your filing-status threshold for the year.
If you are below the threshold, file Form 8995; if you are in or above the range, gather payroll and fixed-asset records and use Form 8995-A.
Run the applicable-percentage math (SSTB) or the wage/property cap (non-SSTB) using the worked examples above.
Confirm the 2026 $400 minimum if you are an active owner with at least $1,000 of QBI.
Check your state’s conformity, and call a CPA before the April 15 deadline if you are anywhere near the range.

Frequently Asked Questions

What is the QBI phase-out range for 2025? $50,000 for single filers and $100,000 for joint filers. It runs from $197,300 to $247,300 (single) and $394,600 to $494,600 (married filing jointly) for tax year 2025.

Does the QBI deduction still exist after 2025? Yes. The One Big Beautiful Bill Act made the Section 199A deduction permanent starting in 2026, removing the old expiration date that would have ended it after the 2025 tax year.

Can an SSTB owner ever get the full QBI deduction? Yes, but only if taxable income stays below the threshold — $197,300 single or $394,600 joint for 2025. Above the top of the range, an SSTB’s deduction drops to zero.

How wide is the phase-out range in 2026? $75,000 for single filers and $150,000 for joint filers, widened by OBBBA from the 2025 figures of $50,000 and $100,000. The base thresholds still adjust for inflation.

Which form do I use if I’m in the phase-out range? Form 8995-A. The simplified Form 8995 is only for taxpayers below the threshold; once you reach or exceed it, you must use the longer 8995-A.

Is the income threshold measured before or after the QBI deduction? Before. You compare your taxable income before subtracting the QBI deduction to the threshold for your filing status.

What is the new $400 minimum QBI deduction? A guaranteed floor starting in 2026. Active owners who materially participate and have at least $1,000 of QBI get at least $400, even if other limits would reduce them to zero.

Does the wage limit apply to non-SSTB businesses? Yes. Above the threshold, every business — SSTB or not — is capped at the greater of 50% of W-2 wages, or 25% of wages plus 2.5% of qualified property.

What happens to an SSTB above the top of the range? The deduction is zero. For 2025, SSTB income above $247,300 single or $494,600 joint produces no QBI deduction at all.

Do all states allow the QBI deduction? No. Most states that start from federal AGI do not follow it, so it lowers only your federal tax. Check your state revenue agency to confirm.

Can I lower my income to escape the phase-out? Yes. Larger retirement-plan contributions or deductible equipment purchases before December 31 can pull taxable income under the threshold and restore part or all of the deduction.
