As a 1099 physician, you can deduct legitimate business expenses that W-2 employees cannot—potentially saving $15,000-40,000 in taxes annually. But you need to know what's deductible, how to document it properly, and which expenses trigger IRS audits.

This comprehensive guide covers every allowable business expense for 1099 physicians, exact documentation requirements, common mistakes that cost thousands, and how to maximize deductions while staying audit-proof.

The Tax Advantage of 1099 Status

W-2 employees can't deduct most work-related expenses anymore (eliminated by 2017 tax reform). But as a 1099 independent contractor, you can deduct ordinary and necessary business expenses, reducing both:

Category 2: Continuing Medical Education (CME)

Fully Deductible:

Strategic timing: If attending a CME conference in desirable location, ensure the conference is the primary purpose of the trip. Personal days before/after are not deductible, but conference days + reasonable travel days are fully deductible.

CME Travel Deduction Strategy:

Deductible scenario:

Deductible: 6 days hotel (Days 1-6), airfare, meals during conference days, conference registration

Annual deduction: $2,000-8,000 depending on number of states and specialties

Calculation Methods:

Method 1: Standard Mileage Rate (Simpler):

Method 2: Actual Expenses (More Complex):

Documentation Requirements:

Mileage log must include:

Tools: MileIQ, Everlance, TripLog apps (auto-track with GPS)

Critical: Without a contemporaneous mileage log, IRS will disallow 100% of vehicle deductions even if they were legitimate. Use an app from day one.

Category 6: Meals and Entertainment

Documentation: Flight confirmations, hotel receipts, rental car agreements, work schedule showing assignment

Example:

1099 income: $300,000

Tax savings: $70,500 —” 52% = $36,660

Special Deduction: Qualified Business Income (QBI) Deduction

1099 physicians may qualify for the Section 199A QBI deduction:

Strategy: If your income is below phase-out, you automatically get 20% deduction on net profit. This is HUGE.

Example: $200,000 net 1099 income → $40,000 QBI deduction = $18,800 tax savings

Common Mistakes That Cost Thousands

Mistake #1: Not Tracking Mileage

Without a contemporaneous log, you lose ALL vehicle deductions. Start tracking from day one with an app.

Mistake #2: Mixing Personal and Business Expenses

Using your business account for personal expenses makes everything harder to track and raises audit red flags. Keep them completely separate.

Mistake #3: No Documentation

IRS rule: No receipt = no deduction. Keep everything, even small purchases.

Mistake #4: Deducting 100% of Mixed-Use Items

Cell phone you also use personally? Can't deduct 100%. Be honest about business use percentage.

Mistake #5: Claiming Lavish or Unreasonable Expenses

$500 steakhouse dinners, first-class flights when coach is available—these raise audit flags. Reasonable business expenses only.

Mistake #6: Home Office When You Don't Qualify

Guest bedroom you work in "sometimes" doesn't qualify. Need dedicated, exclusive use space.
