Avoid Losing QBI Over $276,750: Specified Service Trade Rules (U.S.)

October 4, 2026
Avoid Losing QBI Over $276,750: Specified Service Trade Rules (U.S.)

Your business is a specified service trade or business, or SSTB, if it falls into a list of service fields defined by 26 CFR § 1.199A-5, and that classification can phase out or eliminate your Section 199A deduction once your taxable income rises above set thresholds. The regulation and the IRS Instructions for Form 8995-A govern the determination and the math that follows.

TL;DR:

  • Businesses with revenue from reputation or skill-based services in listed fields are more likely to be classified as SSTBs and face deduction phase-outs at higher income levels.
  • The SSTB status becomes relevant only once taxable income exceeds the 2026 thresholds of $201,750 for singles and $403,500 for joint filers, with the deduction shrinking on a sliding scale.
  • A business's de minimis revenue from service activities must stay below 10% for firms under $25 million in gross receipts, or 5% for larger firms, to avoid SSTB classification.
  • Proper documentation, separate invoicing, and monitoring of ownership and revenue sources are critical to maintaining non-SSTB status and avoiding IRS penalties.
  • Ongoing SSTB and QBI planning, including salary modeling and revenue tracking, can significantly optimize tax outcomes for near-threshold businesses.

What counts as an SSTB: listed fields and the reputation-or-skill test

The regulation names specific fields that automatically trigger SSTB status. Health, law, accounting, actuarial science, performing arts, consulting, athletics, financial services, brokerage services, and investing, investment management, trading, or dealing in securities, partnership interests, or commodities all qualify under 26 CFR § 1.199A-5. Beyond that list, a business can still land in SSTB territory through the reputation-or-skill test: if the principal asset of the trade or business is the reputation or skill of its owners or employees, it counts as an SSTB even outside the named fields.

A few points matter for owners sorting through this:

  • The listed fields cover a defined set of service categories, not every professional service.
  • The reputation-or-skill test is narrower than it sounds and typically applies when income comes from endorsements, appearance fees, or licensing of a person's identity.
  • Wages earned as an employee are never treated as qualified business income, so employee status removes the question entirely.

Businesses that sell products, equipment, or property, rather than personal expertise, generally sit outside this classification, even when they operate in an adjacent industry.

Income thresholds and phase-in rules that determine when SSTB income is excluded

SSTB status only matters once your taxable income clears a set floor. For the 2026 tax year, the phase-in range starts at taxable income over $201,750 for single filers and $403,500 for married filing jointly, and it closes at $276,750 and $553,500 respectively, according to the Instructions for Form 8995-A. Below the floor, SSTB status does not affect your deduction at all.

Within the phase-in range, the applicable percentage of QBI, W-2 wages, and UBIA you can use shrinks on a sliding scale, according to the Instructions for Form 8995-A, until it reaches zero at the ceiling. A single SSTB owner with taxable income at $220,000 retains a meaningful share of QBI. The same owner at $260,000 keeps only a small fraction. Once income exceeds $276,750 (single) or $553,500 (joint), the SSTB's QBI is excluded from the deduction entirely.

SSTB QBI phase-in threshold ranges

A trade or business with mixed revenue does not automatically become an SSTB just because part of it touches a listed field. Treasury's de minimis rule sets the line based on gross receipts, as laid out in 26 CFR § 1.199A-5:

  • For businesses with gross receipts of $25 million or less, SSTB status applies only if specified service income is 10% or more of total gross receipts.
  • For businesses above that $25 million mark, the threshold drops to 5%.
  • Common ownership of 50% or more between a service provider and an SSTB can cause the provider's activity to be treated as part of the SSTB for those owners.

The related-party rule catches owners off guard most often when a cleaning, staffing, or administrative entity shares majority ownership with a professional practice. Clean contracts, arm's-length pricing, and separate invoicing help preserve the non-SSTB status of the supporting entity.

Pro Tip: Keep service and non-service revenue on separate invoices and ledgers from day one, since the de minimis calculation looks at how receipts are actually documented, not how you describe the business.

Service and non-service revenue separated

Reporting and compliance: Form 8995-A, Schedule A, and RPE/PTP K-1s

Once you know your SSTB status, the forms you file depend on your income level and entity structure.

  1. Taxpayers with taxable income below the phase-in floor generally use the simpler Form 8995, since SSTB limits do not yet apply.
  2. Taxpayers above the floor, or anyone with an SSTB in the phase-in range, use Form 8995-A along with Schedule A to calculate the reduced applicable percentage, per the Instructions for Form 8995-A.
  3. Owners of pass-through entities rely on Schedule K-1, where the entity must report each owner's share of QBI, W-2 wages, unadjusted basis immediately after acquisition, and whether the activity is an SSTB, as required under 26 CFR § 1.199A-6.
  4. If an SSTB determination changes after filing, the entity may need to issue corrected K-1s and the owner may need to amend a return while the statute of limitations remains open.

Keep documentation on revenue sources, ownership percentages, and any contracts between related entities. These records are what support your position if the IRS questions the classification later.

Practical examples and a short SSTB checklist for owners

A solo CPA firm earning all its revenue from tax preparation and advisory work is a clear SSTB, no gray area. A landscaping company that occasionally offers a consulting add-on, but keeps that revenue under the 10% de minimis line, stays outside SSTB treatment for the whole business. A physical therapy practice that also sells branded recovery equipment through a separate LLC may keep the equipment sales outside SSTB rules, provided the two revenue streams are genuinely separated in contracts and books.

Run through this before assuming either outcome:

  • Where does the majority of revenue actually come from, service delivery or goods and property?
  • Are consulting or advisory fees billed and tracked separately from other services?
  • Does gross receipts composition stay under the 10% or 5% de minimis threshold?
  • Is there 50% or greater common ownership with a listed SSTB field?
  • Do payroll and property holdings suggest a capital-intensive model rather than a reputation-driven one?
  • Would a reasonable observer say clients are paying for your name and skill, or for a defined deliverable?

Pro Tip: When two or three checklist items point in different directions, that is usually the signal to get a second opinion before you file, not after. The Tax Refinery's deeper SSTB checklist for QBI walks through these same questions in more detail for owners and preparers.

What to do next: compliance, documentation, and planning levers

Once you have a working answer on SSTB status, a few concrete steps keep you ahead of the issue instead of reacting to it at filing time.

  1. Pull current-year revenue by source and confirm your de minimis percentage before year-end, not after.
  2. Review ownership structures across related entities for the 50% common-ownership trigger.
  3. Model whether an aggregation election or S-corp salary adjustment changes your position relative to the phase-in thresholds.
  4. Revisit accountable plan reimbursements and timing of income recognition if you are near the phase-in floor.

Treat a sudden jump in consulting or advisory revenue, a new shared-ownership entity, or taxable income creeping toward $201,750 (single) or $403,500 (joint) as red flags worth a call to your preparer before the return is due, not during an extension scramble.

How some tax advisory firms approach SSTB risk for clients

Most SSTB problems surface at filing time, when it is too late to fix them. Year-round monitoring catches a shift in revenue mix or ownership structure while there is still time to adjust. That is the difference between a once-a-year filer and a standing advisory relationship, and it is how some firms work with business owners who sit near these thresholds.

FAQ

How do I know if my business is a specified service trade or business?

Check whether your business falls into a listed field under 26 CFR § 1.199A-5, such as health, law, accounting, or consulting, or whether its principal asset is the reputation or skill of its owners. If specified service revenue stays under the de minimis threshold relative to total gross receipts, the business as a whole may avoid SSTB treatment.

How do I know if I am eligible for QBI?

You generally qualify for the QBI deduction if you have qualified business income from a sole proprietorship, partnership, S corporation, or similar pass-through entity, and wages earned as an employee never count. Eligibility and the amount you can claim depend on your taxable income relative to the 2026 phase-in thresholds detailed in the Instructions for Form 8995-A.

Can you give me an example of an SSTB?

A solo attorney's practice, where clients pay for legal advice and representation, is a textbook SSTB under 26 CFR § 1.199A-5. A financial advisory firm or a consulting practice built around an owner's expertise fits the same pattern.

What is the difference between an SSTB and QBI?

QBI is the income amount eligible for the Section 199A deduction, while SSTB is a classification that can limit or eliminate access to that deduction once taxable income exceeds the phase-in ceiling. A business can generate QBI and still lose the deduction entirely if it is an SSTB and income is high enough, per 26 CFR § 1.199A-5.
