The amount of taxes a dermatologist might pay depends on various factors, including their income level, filing status, deductions, credits, and whether they are an employee or self-employed (e.g., running a private practice). Dermatologists often have high incomes due to the specialized nature of their profession, which can place them in higher federal and state tax brackets. This answer will provide an overview of the factors affecting a dermatologist’s tax liability and illustrate potential tax calculations, citing authoritative sources.

5. Example Tax Calculation
Disclaimer: This is a simplified example for illustrative purposes. Actual tax liability can be more complex.
Assumptions:
- Dermatologist’s Gross Income: $400,000
- Filing Status: Married Filing Jointly
- Business Expenses: $100,000
- Itemized Deductions (after limitations): $30,000
- State Income Tax Rate: 5%
a. Calculate Net Income
- Gross Income: $400,000
- Minus Business Expenses: $400,000 – $100,000 = $300,000
b. Adjusted Gross Income (AGI)
- AGI: $300,000
c. Taxable Income
- AGI: $300,000
- Minus Itemized Deductions: $300,000 – $30,000 = $270,000
d. Federal Income Tax
- Using 2023 Tax Brackets for Married Filing Jointly:
- 10% on first $22,000: $2,200
- 12% on $22,000 to $89,450: ($89,450 – $22,000) * 12% = $8,094
- 22% on $89,450 to $190,750: ($190,750 – $89,450) * 22% = $22,242
- 24% on $190,750 to $270,000: ($270,000 – $190,750) * 24% = $19,080
- Total Federal Income Tax:
- $2,200 + $8,094 + $22,242 + $19,080 = $51,616
e. Self-Employment Tax
- Social Security Portion:
- Maximum taxable earnings: $160,200
- Social Security Tax: $160,200 * 12.4% = $19,862.40
- Medicare Portion:
- Total Net Income: $300,000
- Medicare Tax: $300,000 * 2.9% = $8,700
- Additional Medicare Tax:
- Income over $250,000 for Married Filing Jointly is subject to an additional 0.9% Medicare tax.
- Additional Medicare Tax: ($300,000 – $250,000) * 0.9% = $450
- Total Self-Employment Tax:
- $19,862.40 + $8,700 + $450 = $29,012.40
- Deductible Part of Self-Employment Tax:
- Half of the self-employment tax is deductible.
- Deduction: $29,012.40 / 2 = $14,506.20
- Adjusted Taxable Income:
- Taxable Income after deduction: $270,000 – $14,506.20 = $255,493.80
- Recalculate Federal Income Tax:
- This would slightly lower the federal tax, but for simplicity, we’ll proceed with the original calculation.
f. State Income Tax
- State Tax Rate: 5%
- State Income Tax:
- Taxable Income: $270,000
- State Tax: $270,000 * 5% = $13,500
g. Total Tax Liability
- Federal Income Tax: $51,616
- Self-Employment Tax: $29,012.40
- State Income Tax: $13,500
- Total Taxes: $51,616 + $29,012.40 + $13,500 = $94,128.40
