If You're a Doctor, Lawyer, or Consultant Earning Over $383K, You Just Lost Your 20% QBI Deduction. Here's the Workaround.

The 20% Qualified Business Income (QBI) deduction under Section 199A is one of the most valuable tax breaks available to pass-through business owners — sole proprietors, S-corp shareholders, and partnership members. For most service businesses, it's worth tens of thousands of dollars per year.

There's a catch. For owners of Specified Service Trades or Businesses (SSTBs) — defined as businesses whose principal asset is the reputation or skill of one or more employees — the deduction phases out completely above income thresholds. In 2026, those thresholds are:

• $383,900 for single filers
• $483,900 for married filing jointly
• Phaseout range: $50K above the threshold for singles ($433,900 fully phased out), $100K above for MFJ ($583,900 fully phased out)

If your taxable income exceeds the upper phaseout, you get zero QBI deduction. For a high-earning physician, dentist, lawyer, or accounting practice owner, this can mean $30K-$80K of additional federal tax per year compared to a non-SSTB business owner with the same income.

Here is what counts as an SSTB, what doesn't, and three legal workarounds I have used over 45 years of tax practice to recover most or all of the deduction.

What the IRS counts as an SSTB

The Section 199A regulations spell it out. SSTBs include:

• Health: physicians, dentists, veterinarians, pharmacists, nurses, physical therapists, psychologists
• Law: lawyers, paralegals, mediators, arbitrators
• Accounting: accountants, enrolled agents, return preparers
• Actuarial science
• Performing arts: actors, musicians, directors
• Consulting: management consultants, IT consultants, financial advisors providing advice
• Athletics: athletes, coaches
• Financial services: investment management, wealth management, brokerage services
• Brokerage services
• Investing and investment management
• Trading or dealing in securities, partnership interests, or commodities
• Any business where the principal asset is the reputation or skill of one or more employees (catch-all)

What is NOT an SSTB:

• Engineering and architecture (specifically excluded by statute)
• Real estate (rental real estate, brokerage of real estate, REITs)
• Insurance brokerage (specifically excluded)
• Manufacturing
• Construction and trades (HVAC, plumbing, electrical, etc.)
• Most retail and product businesses
• Software-as-a-service (where the asset is the platform, not the founder's reputation)

This is critical: construction, trades, manufacturing, and most field-service businesses do NOT lose the QBI deduction at high income. The phaseout primarily affects professional services.

The math: what the deduction is actually worth

For pass-through business owners under the income threshold:

• 20% deduction on QBI
• For a physician with $400K of QBI: $80K deduction × 37% top federal rate = $29,600 federal tax savings
• Plus 5-13% state tax savings depending on jurisdiction (most states conform to Section 199A, but California, New York, and a handful of others do not)

For SSTB owners above the income threshold: deduction reduced to $0. Net cost: ~$30K-$80K of additional federal tax per year.

This is why high-earning doctors and lawyers often pay an effective tax rate 5-7 percentage points higher than business owners with similar income in non-SSTB industries. The IRS designed Section 199A to favor "real" businesses with capital and labor — not personal-service practices.

Workaround 1: Reduce taxable income below the threshold

The most direct approach: reduce your taxable income enough to fall back below the SSTB phaseout threshold and recover the full deduction. The math often makes this profitable even if it requires deferring income.

Tools available:

• Maximize retirement contributions: Solo 401(k) ($77K), Cash Balance Plan ($150K-$300K for owners over 45) — see our cash balance plan guide
• HSA contributions if you have a high-deductible health plan: $4,150 single / $8,300 family in 2026
• Defined benefit plan: properly designed, can deduct $200K+ in additional pre-tax contributions
• State tax pre-payment (where applicable): pay state estimated tax in December for the prior year's deduction
• Charitable giving via a Donor Advised Fund: bunch multiple years of contributions into one tax year

Example: physician with $580K taxable income (married filing jointly). $100K above the upper phaseout. By contributing $200K to a cash balance plan, taxable income drops to $380K — below the threshold. Full $80K QBI deduction restored. Combined tax benefit: ~$30K from QBI restoration + ~$74K from the $200K deduction at 37% = $104K of total tax savings.

The cash balance contribution effectively pays for itself through the recovered QBI alone, before counting the underlying retirement deferral benefit.

Workaround 2: Split the business into SSTB and non-SSTB components (carefully)

Some practice structures legitimately have both SSTB and non-SSTB activities. The Section 199A regulations permit separate treatment of distinct trades or businesses if certain requirements are met. Common examples:

Medical practice with imaging or lab equipment:

• The professional services component (physician work) is SSTB
• The imaging/lab equipment rental to the practice can be a separate trade or business
• The equipment rental income is NOT SSTB and qualifies for the full QBI deduction at any income level

Law firm with real estate holdings:

• Legal services component is SSTB
• Real estate ownership and rental to the firm is a separate trade or business
• Rental income qualifies for QBI deduction (subject to W-2 wage and basis limits)

Dental practice with equipment leasing entity:

• Dental services are SSTB
• A separate equipment-leasing LLC owns expensive dental equipment and leases it to the practice
• The leasing entity's income qualifies for QBI without the SSTB phaseout

Important caveats:

The IRS issued anti-abuse rules in the final 199A regulations specifically targeting "crack-and-pack" structures. The rules require that the non-SSTB business have economic substance — real activity, real risk, real assets. You cannot split an SSTB into "the SSTB part" and "the SSTB billing department" and claim the billing department is non-SSTB.

The non-SSTB business must:

• Have its own employees, equipment, or other distinct assets
• Generate economic returns commensurate with its capital and labor investment
• Not exist solely as a tax-avoidance vehicle

Done right, this is a legitimate and valuable strategy. Done sloppily, it's audit bait. Get an experienced tax attorney or EA involved.

Workaround 3: C-corp election for some or all of the business

For some high-income SSTB owners, electing C-corp status is the simplest workaround. C-corps are subject to a flat 21% federal tax rate at the entity level — significantly lower than the 37% top individual rate that applies to pass-through income.

When this works:

• Owner is comfortable leaving most profit in the company (not distributing as personal income)
• Profits will be reinvested in growth, equipment, or hiring
• Owner has additional income sources to fund personal lifestyle
• Long-term plan involves selling the business (Qualified Small Business Stock under Section 1202 can exclude up to $10M of gain on C-corp sale)

When this doesn't work:

• Owner needs to take all profit as personal income (double taxation: 21% corporate + dividend tax on distribution = often higher total than pass-through)
• State taxes vary substantially (California's 8.84% corporate rate stacks unfavorably)
• Personal Service Corporation rules may force a flat 35% rate on certain professional service C-corps

For a physician earning $700K who can live on $300K and reinvest the rest, C-corp election can save $40K-$80K/year vs. pass-through. For a lawyer earning $700K who needs all $700K personally, the C-corp election usually loses money.

Workaround 4: Wage and basis maximization (above-threshold partial deduction)

Even after the SSTB upper threshold, some QBI deduction can survive if your business has substantial W-2 wages or qualified property basis. The deduction at high income is capped at the greater of:

• 50% of W-2 wages paid by the business, OR
• 25% of W-2 wages + 2.5% of unadjusted basis in qualified property

For SSTBs above the phaseout, this cap calculation reduces to zero — no SSTB QBI is deductible at high income, period. So this lever doesn't help SSTBs.

But for owners with multiple businesses (some SSTB, some non-SSTB), the wage/basis math matters for the non-SSTB component. Strategically structuring W-2 compensation versus distributions, and timing of equipment purchases, can materially increase the non-SSTB QBI deduction.

Three things to do this quarter

If you're an SSTB owner above the phaseout (or close to it):

Action 1: Calculate your projected 2026 taxable income with current contribution levels. If you're within $50K-$100K of the phaseout threshold, additional retirement contributions become ROI-positive even if you wouldn't make them otherwise.

Action 2: If your taxable income exceeds the upper phaseout by more than $200K, evaluate cash balance plan eligibility. The combination of QBI restoration plus the underlying retirement deduction often produces 40-50% combined effective tax savings on incremental contributions.

Action 3: If your business has obvious non-SSTB components (equipment, real estate, related-but-separate services), consult an EA or tax attorney about whether a separate-entity structure passes the economic substance test.

The QBI deduction was intentionally designed to favor capital-intensive businesses over service-only businesses. The phaseout for SSTBs is a feature, not a bug. But the IRS also gave you the tools to legally restructure and recover most of the deduction. Most CPAs don't proactively walk owners through these moves. The owner who knows them captures the savings.
