Most of the deductions on the popular therapist tax lists apply to a psychiatric practice too: rent, software, health insurance premiums, retirement contributions, the home office. What those lists miss is the prescriber layer, several thousand dollars a year of DEA registrations, multi-state licenses, board fees, malpractice tail exposure, and collaborating-physician fees, and one assumption that breaks at prescriber incomes: that you qualify for the 20% qualified business income (QBI) deduction. Medicine is a specified service trade or business, so for 2026 that deduction phases out between $201,750 and $276,750 of taxable income for single filers ($403,500 to $553,500 married filing jointly) and is worth exactly $0 above the top of the range. A cash-pay psychiatrist with a full panel can sail past that line without noticing.
This is general tax information, not advice on your return. The federal figures below are 2026 numbers with primary sources linked; how they apply to you depends on facts a blog cannot see. Run anything load-bearing past a CPA who works with medical practices.
Why do therapist tax guides go wrong for prescribers?
The guides are written for a reader with a $60,000 to $150,000 net income and no prescribing overhead, and they fail prescribers in two ways. First, incompleteness: the widely shared deduction lists (we checked the most-cited ones in August 2026) cover meals, mileage, and marketing but never mention DEA registration, tail coverage, or collaborating-physician fees, which are among a prescriber's largest professional line items. Second, and more expensive, the QBI advice: those lists either present the 20% pass-through deduction as automatic or skip the income limits entirely. At typical therapist incomes it usually is automatic. At the incomes a full cash-pay psychiatric practice generates, documented in our income breakdown, the deduction shrinks and then disappears, and planning around that cliff matters more than any individual write-off on the list.
What can psychiatrists and PMHNPs deduct that therapists never see?
The prescriber-specific inventory below is fully deductible as ordinary business expenses, and it is worth tracking as its own category because it is the part no generic bookkeeper flags. Typical costs are planning ranges; your states and carrier set the real numbers.
| Line item | Typical cost | Notes |
|---|---|---|
| DEA registration | $888 per 3-year cycle, per state | Deduct in the year paid. Telehealth practices registered in several states multiply this line. |
| State licenses | $200 to $800 per state, initial; renewals vary | Medical or APRN licenses, plus IMLC or compact fees. |
| Board certification | A few hundred dollars a year (planning number) | ABPN or ANCC initial exams and continuing-certification fees. |
| Malpractice premium | $2,000 to $5,000 a year for solo psychiatry | Premiums and the tail payment are both deductible; the tail can be 1.5 to 2x your final premium in one lump. |
| Collaborating physician (PMHNP) | $500 to $2,000 a month in restricted states | Often a PMHNP's largest overhead line; the full cost breakdown covers arrangement types. |
| State controlled-substance registration | Varies; a handful of states charge separately | Check whether your state requires its own CS registration on top of the DEA number. |
| CME and travel | Registration fully deductible; meals at 50% | Travel deducts when the trip is primarily for the conference; document the agenda. |
| Prescribing stack | $50 to $300 a month | EPCS tokens, e-fax, PDMP-adjacent tools, HIPAA-compliant phone. |
Two nuances worth a sentence each. The tail payment surprises people because it arrives as one five-figure bill the year you leave a claims-made policy, and it is deductible in that year, which is often a year your income also dropped. And CME travel is the most audited line on this table: a conference with a spouse attached needs clean records showing the business purpose carried the trip.
Which everyday deductions still apply to a psychiatric practice?
Everything on the standard self-employment list works the same for you as for any practice owner. The home office deduction applies to a telehealth practice run from a dedicated room: the simplified method pays $5 per square foot up to 300 square feet, and the regular method deducts the business share of actual housing costs, usually more for a large office in an expensive home. Half of self-employment tax is deductible, and self-employed health insurance premiums come off above the line; the 1099 vs W-2 breakdown runs that full math against an employed salary. Pre-tax retirement contributions are the largest controllable line: for 2026 a solo 401(k) takes $24,500 in employee deferrals and up to $72,000 total with employer profit-sharing. Your launch spending mostly deducts too; the startup cost budget itemizes what you will have spent before your first patient. If you run on Eureka, the all-in subscription (EHR, eRx, fax, and the bundled malpractice coverage) lands as one clean deductible line, which spares you allocating six vendor invoices at tax time.
Is psychiatry an SSTB, and what is the QBI deduction worth?
Yes. Section 199A gives pass-through owners a deduction of up to 20% of qualified business income, and it defines a specified service trade or business (SSTB) by a list of fields that begins with health. A psychiatric practice, an NP practice, and a therapy practice are all SSTBs. Below the taxable-income threshold, SSTB status changes nothing and you take the full deduction. Above it, SSTB status phases the deduction down to zero. The 2025 tax law made the deduction permanent and widened the phase-out ranges starting in 2026, so the numbers you may have seen for earlier years are out of date. The 2026 figures, per IRS Rev. Proc. 2025-32:
| Filing status | Full 20% deduction below | Phase-out range | Deduction gone above |
|---|---|---|---|
| Single or head of household | $201,750 | $201,750 to $276,750 | $276,750 |
| Married filing jointly | $403,500 | $403,500 to $553,500 | $553,500 |
Married filing separately has its own slightly different numbers. These thresholds are measured on taxable income, not practice revenue and not practice profit, a distinction the generic guides blur. Taxable income is what remains after your business expenses, retirement contributions, half of self-employment tax, health insurance, and the standard or itemized deduction. A practice grossing $400,000 can land under the single-filer threshold or far above it depending on those lines, which is why the cliff is a planning problem rather than a fixed fact about your practice.
What does the phase-out cost at a real psychiatrist's income?
Run the numbers on one practice filed two ways. Assume a solo cash-pay psychiatrist, sole proprietor, no employees, $330,000 practice profit, roughly $16,000 deducted as half of self-employment tax (the 12.4% Social Security piece caps at the $184,500 wage base for 2026), a $24,500 solo 401(k) deferral, and ordinary personal deductions.
- Filed single, taxable income lands near $270,000, inside the phase-out range and close to its top. The therapist-list promise of roughly 20% of QBI, about $60,000 of deduction, has collapsed to a small fraction of that, and $7,000 more income zeroes it.
- Filed jointly with household taxable income of $380,000, the same practice takes the full deduction, roughly $60,000, worth about $19,000 of federal tax at a 32% marginal rate.
Identical practice, five-figure swing, and nothing about it appears in a deduction list written for $90,000 earners. Inside the phase-out range the arithmetic compounds: at $240,000 single, only 49% of QBI still counts (the range is $75,000 wide, and you are 51% through it), and a second limit based on W-2 wages phases in on top, which bites hard for a sole proprietor whose practice pays no wages at all. The exact mid-range number is a spreadsheet job for your CPA; the endpoints are what to know cold: full deduction below $201,750 single, zero above $276,750.
Can you get the QBI deduction back?
Sometimes, and the lever is taxable income. If a Q4 projection puts you within $20,000 to $40,000 of a threshold, pre-tax contributions can pull you back under it or deeper into the range: the solo 401(k)'s $72,000 total capacity is the big dial, an HSA adds a few thousand more if you carry a qualifying high-deductible plan, and cash-basis timing (invoicing intakes in January rather than December) shifts income at the margin. There is a wrinkle: for a sole proprietor, retirement contributions also reduce QBI itself, so the deduction you revive is 20% of a smaller number. Below the cliff, 20% of something still beats 20% of nothing, and the contribution was already worth its marginal rate on its own.
David Cohen, CPA, JD, who reviewed this post: "The psychiatrists I see overpay the same way every year: they hunt $300 deductions in October while sitting $15,000 over the SSTB line. Model taxable income in early Q4, while the retirement contribution that pulls you back under the threshold can still be funded. That one move can be worth more than every receipt in your shoebox combined."
One paragraph on the S-corp question, because every tax thread eventually lands there: an S election can reduce self-employment tax by splitting income into salary and distributions, but it rewires the QBI math at the same time (your own salary comes out of QBI, and the wage limit starts counting it), and above the SSTB cliff it revives nothing. Whether it nets out positive depends on your income, your state, and payroll costs. The entity decision deserves its own full treatment, and a CPA's projection, before you file anything.
What should you do before December 31?
Three moves cover most of the value. Track the prescriber inventory from the table above as its own expense category starting now, so nothing on it gets missed in April. Project taxable income in early Q4 against the $201,750 and $403,500 thresholds and decide your retirement contribution with the QBI cliff on the same page, since that interaction is where the real money is. And if your practice profit has crossed $250,000, move from tax software to a CPA who works with physician practices; the fee is itself deductible, and the SSTB modeling alone typically covers it.
