What the IRS Counts as Self Employment Income

If you receive income reported on Form 1099 instead of a W 2, the IRS considers you self employed. Your earnings must be reported on Schedule C and your net earnings are calculated on Schedule SE. According to the Self Employed Individuals Tax Center, you must file a tax return if your net earnings from self employment are 400 dollars or more for the year.

For independent cardiologists, this includes payments for professional services, consulting work, call coverage, and any income where taxes are not withheld by an employer. Even if you work at a single hospital, you are treated as a business for tax purposes.

How to Calculate Self Employment Tax as a 1099 Doctor

Self employment tax covers Social Security and Medicare contributions. The calculation follows the method in the Schedule SE Instructions.

  1. Determine your net profit on Schedule C
  2. Multiply that amount by 0.9235 to find net earnings
  3. Multiply net earnings by 15.3 percent for self employment tax
  4. Deduct the employer equivalent portion of your self employment tax on Form 1040

Example

Revenue: $520 000

Expenses: $120 000

Net profit: $400 000

Net earnings = $400,000 times 0.9235 = $369,400

Self employment tax = $369,400 times 0.153 = $56,502

Employer equivalent portion you may deduct on Form 1040 = $28,251

This deduction lowers your taxable income but does not change the amount of self employment tax you owe.

Top Tax Deductions 1099 Doctors Often Overlook

The IRS allows deductions for expenses that are ordinary and necessary for your business. Publication 334 outlines these rules for small businesses.

Common deductible expenses for independent physicians include

  • Malpractice insurance
  • Licensing and certification fees
  • Continuing medical education
  • Medical supplies and equipment
  • Office rent and utilities
  • Travel and mileage for professional services
  • Business use of phone and internet

The IRS expects receipts and contemporary records that show how each expense relates to your medical practice.

Can 1099 Doctors Deduct Their Health Insurance Premiums

Yes. Self employed individuals may deduct the cost of health insurance premiums for themselves and their families if they are not eligible for employer sponsored coverage.

This deduction appears on Form 1040 and reduces adjusted gross income.

Retirement Plan Options for 1099 Doctors

Independent physicians may use the retirement plans described in IRS guidance for self employed individuals.

Solo 401 k

Allows employee deferrals and employer contributions.

See:: One Participant 401 k Plans, IRS.

SEP IRA

Allows contributions of up to 25 percent of net earnings from self employment.

See:: SEP Plans, IRS.

Both plans reduce taxable income and support long term retirement savings.

When a 1099 Doctor Should Consider S Corporation Status

High earning physicians sometimes elect S corporation treatment to reduce self employment tax. Under IRS rules, an S corporation must pay reasonable compensation through payroll and treat the remainder as distribution.

See: IRS S Corporation guidance.

This decision should be evaluated based on net income, consistency of revenue, and the ability to follow payroll and recordkeeping requirements.

Recordkeeping and Quarterly Tax Payments

Because no employer withholds taxes from 1099 income, you must make quarterly estimated tax payments using Form 1040 ES. Publication 334 outlines the IRS expectations for small business recordkeeping.

Maintain clear records of

  • Gross receipts and invoices
  • Expense documentation
  • Mileage and travel logs
  • Health insurance payments
  • Retirement plan contributions

Accurate records help protect deductions and support your Schedule C and Schedule SE reporting.

Work With a Tax Professional

Taxes for independent physicians can feel complex, especially when you want to ensure your deductions, retirement contributions, and entity decisions follow current IRS rules. When you want clear guidance and confidence in your filing, meeting with a specialist is the most effective option.
