QBI for marketers: probably not an SSTB — do not blow it anyway
The short answer
Good news for agencies: advertising and marketing services are generally NOT specified service businesses, so high-income agency owners can keep the 20% QBI deduction where consultants lose it. Two ways to blow it anyway: letting consulting-style revenue dominate (advice-for-fees is SSTB), and running an all-contractor shop that fails the W-2 wage limit above the thresholds — no wages, no deduction cap to stand on.
The planning levers
- Audit your revenue lines: execution (campaigns, content, media, builds) vs pure advisory — know your mix.
- Mind the wage limit: above the thresholds, your own reasonable S-corp salary and any employee payroll are what preserve the deduction.
- Coordinate the whole triangle: salary up = payroll tax up, QBI down, wage-limit capacity up — one calculation, run annually.
- Contract precisely: where advisory and execution genuinely differ, document them as they are.

Frequently asked questions
Is a marketing agency an SSTB?
Often not. Advertising and marketing services are not on the SSTB list; the regulations even include an example treating an advertising business favorably. But revenue that is really consulting — advice for fees — is an SSTB, so mixed agencies need to look at their actual revenue lines.
Why does SSTB status matter?
Above the income thresholds, SSTB owners lose the 20% deduction entirely; non-SSTB owners keep it subject to W-2 wage and property limits. For a high-income agency owner, that is the whole deduction.
What are the W-2 wage limits?
Above the thresholds, the deduction caps at the greater of 50% of W-2 wages paid, or 25% of wages plus 2.5% of qualifying property. All-contractor agencies can find themselves wage-poor at exactly the wrong moment.
Can how I invoice really change my deduction?
Characterization follows reality, not labels — but where your work genuinely spans execution and advice, tracking and contracting them separately can matter at the thresholds. This is precision work for your CPA, not creative writing.
