Can private practice therapists take the QBI deduction?

The SSTB classification: Section 199A regulations define 'health' as a field involving the provision of medical services by professionals in the medical and healthcare fields. Private practice psychologists, psychiatrists, therapists, and counselors fall within this definition. Mental health services are health services for SSTB purposes.

Below the threshold, the deduction is full and straightforward: a therapist with $130,000 in net profit taking the standard deduction ($16,100 single), the SE tax deduction, and a retirement contribution arrives at taxable income below $191,950. The QBI deduction is 20% of qualified business income (roughly 20% of net profit after the SE tax deduction), worth approximately $4,500 to $6,000 in reduced taxable income, saving $1,080 to $1,440 in federal tax at 24%.

In the phase-out range, the deduction is partially available: a therapist with taxable income of $215,000 single is 45% through the $50,000 phase-out window. She receives 55% of the full QBI deduction, not zero. This partial deduction is still meaningful and worth calculating.

Above the upper threshold, the SSTB deduction is zero: a psychiatrist filing single with $350,000 in taxable income has no QBI deduction available from the psychiatric practice. There is no workaround for SSTB income above the cap using W-2 wages or unadjusted basis (those tests help non-SSTB businesses, not SSTBs in the phase-out).

The retirement contribution lever: reducing taxable income with pre-tax retirement contributions (Solo 401(k), SEP-IRA) can push a therapist from above the phase-out into the range where the QBI deduction is partially or fully available. A therapist with $210,000 taxable income who contributes $50,000 to a Solo 401(k) drops to $160,000, below the phase-out threshold, and recovers the full QBI deduction. The combined tax benefit (retirement deduction plus QBI deduction recovery) is the planning payoff.
