Income Profile and SSTB Analysis

Ophthalmologists typically earn net practice income of $300,000–$900,000 per year, with surgical subspecialists (retina, cornea, glaucoma) at the higher end. Ophthalmology is generally treated as a field of health (SSTB) for §199A purposes. However, ophthalmologists with income below the §199A phase-in thresholds ($200,000 single / $400,000 MFJ) are not affected by the SSTB limitation and can claim the full 20% QBI deduction.

The MSO (management services organization) model can preserve the QBI deduction on management fee income charged by the management company to the clinical entities. The management fee must be at arm's length to withstand IRS scrutiny.

S-Corp Election and Salary Planning

Most ophthalmologists with net practice income above $100,000 should elect S-Corp status to reduce FICA taxes. A reasonable salary for an ophthalmologist is typically $180,000–$260,000, depending on subspecialty, geographic market, and hours worked. Subspecialists (retina, cornea) command higher reasonable salaries than general ophthalmologists.

For ophthalmologists above the §199A phase-in thresholds who are classified as SSTBs, the S-Corp election remains valuable for FICA savings even though the QBI deduction is phased out. The FICA savings on distributions above the reasonable salary can be $15,000–$30,000 per year for a high-income ophthalmologist.

Retirement Plan Stack

Ophthalmologists are excellent candidates for the full retirement plan stack: S-Corp Solo 401(k) + cash balance plan. The combination allows pre-tax contributions of $200,000–$400,000+ per year for practitioners in their 50s and 60s.

AgeMax 401(k)Max Cash BalanceTotal Pre-Tax
45$66,000$175,000$241,000
50$73,500$225,000$298,500
55$73,500$280,000$353,500
60$73,500$330,000$403,500

Equipment and Technology Deductions

Ophthalmic practices invest heavily in diagnostic and surgical equipment: slit lamps, OCT machines, visual field analyzers, phacoemulsification systems, laser platforms (LASIK, YAG, SLT), and EHR systems. All of this equipment qualifies for §179 expensing (up to $1,220,000 in 2026) and bonus depreciation (60% in 2026). A LASIK laser platform costing $500,000 can be fully deducted under §179 in the year of purchase, generating a $185,000+ tax savings for a practitioner in the 37% bracket.

Ancillary Revenue and Optical Shop Planning

Many ophthalmology practices operate an optical shop (dispensary) that sells eyeglasses and contact lenses. The optical shop revenue is generally not SSTB income and qualifies for the full §199A QBI deduction regardless of the practitioner's income level. Practices should consider segregating the optical shop into a separate entity to preserve the QBI deduction on optical revenue even if the medical practice income is above the SSTB phase-out threshold.

More Tax Planning FAQs

How does the S-Corp election reduce self-employment tax?
An S-Corp election allows the owner to split income between a reasonable salary (subject to 15.3% FICA on the first $176,100 in 2026) and distributions (not subject to FICA). For a business owner with $200,000 in net profit paying an $80,000 salary, the annual SE tax savings are approximately $15,500–$18,500. The S-Corp must file Form 2553 within 75 days of formation.
What is the Section 199A QBI deduction and how does it apply?
The §199A deduction allows pass-through business owners to deduct up to 23% of qualified business income (QBI) from taxable income (increased from 20% under OBBBA). For taxpayers above $403,500 (MFJ) in 2026, the deduction is limited to the greater of 50% of W-2 wages or 25% of W-2 wages plus 2.5% of qualified property. Specified Service Trades or Businesses (SSTBs) phase out above this threshold.
What retirement plan options are available for self-employed professionals?
Self-employed professionals can establish a Solo 401(k) (up to $70,000 in 2026), a SEP-IRA (25% of net self-employment income up to $70,000), a SIMPLE IRA ($16,500 + $3,500 catch-up), or a Defined Benefit Plan (up to $280,000+ depending on age). The Solo 401(k) is the best option for most self-employed professionals because it allows the highest contributions relative to income.
How does the home office deduction work for self-employed professionals?
Self-employed professionals who use a dedicated home office space exclusively and regularly for business qualify for the home office deduction under §280A. The deduction is calculated as a percentage of home expenses (mortgage interest, utilities, insurance, depreciation) equal to the office square footage divided by total home square footage. The simplified method allows $5/sq ft up to 300 sq ft ($1,500 maximum).
What vehicle deductions are available for self-employed professionals?
Self-employed professionals can deduct vehicle expenses using either the standard mileage rate (70 cents/mile in 2026) or actual expenses. Vehicles with a GVWR over 6,000 lbs qualify for §179 expensing (up to $30,500 for heavy SUVs) and bonus depreciation without luxury auto limits. A mileage log must be maintained for either method. The vehicle must be used more than 50% for business to qualify for accelerated depreciation.
What is the Augusta Rule and how can it benefit business owners?
The Augusta Rule (§280A(g)) allows homeowners to rent their primary or secondary residence to their business for up to 14 days per year. The rental income is completely tax-free to the homeowner, and the business deducts the rent as a business expense. At $2,000–$3,000/day for 14 days, this strategy generates $28,000–$42,000 of tax-free income while the business deducts the same amount.
How does cost segregation apply to business owners who own real estate?
Cost segregation reclassifies building components into shorter depreciation categories eligible for bonus depreciation. For a $1M commercial property, cost segregation typically identifies $150,000–$250,000 of accelerated depreciation, generating $60,000–$100,000 in first-year deductions at the 40% bonus depreciation rate in 2026. A cost segregation study costs $5,000–$15,000 and typically has a 10:1+ ROI.
What is the difference between a sole proprietor and an S-Corp for tax purposes?
A sole proprietor pays self-employment tax (15.3%) on all net profit. An S-Corp owner pays FICA only on their reasonable salary, saving SE tax on distributions. For a business with $200,000 in net profit, the S-Corp saves $15,000–$20,000/year in SE tax. The S-Corp has additional costs (payroll, bookkeeping, tax preparation) of $2,000–$4,000/year, making the break-even point approximately $40,000–$50,000 in net profit.
