7 Mistakes New Plastic Surgery Practices Make in Their First Year

2026-08-21

Avoid common tax pitfalls in your first year of practice. Learn the 7 mistakes new plastic surgery practices make and how to fix them.

Starting a plastic surgery practice is exciting, but the first year is also when tax mistakes can cost you thousands. Many new owners focus on clinical excellence and neglect the business side, especially taxes. Here are the 7 most common tax mistakes new plastic surgery practices make, and how to avoid them.

Mistake 1: Choosing the Wrong Business Structure

Many new practices start as a sole proprietorship or general partnership because it’s easy. But that exposes your personal assets to liability and can cost you more in self-employment taxes. A limited liability company (LLC) or S-corp is usually better for a plastic surgery practice.

What to do this week: Consult a CPA who works with medical practices. If you’re already operating, you can still change your structure before year-end. An S-corp election can save you on self-employment tax, but it requires paying yourself a reasonable salary. The cost of a CPA consultation is $200-$500, but it can save you thousands.

Mistake 2: Not Tracking Vehicle Mileage

If you travel between offices, to surgical centers, or to meet vendors, you can deduct mileage. The IRS mileage rate for 2026 is $0.70 per mile (estimated). That adds up fast. But if you don’t track it, you lose that deduction.

What to do this week: Start a mileage log today. Use an app like MileIQ or a simple spreadsheet. Record the date, miles, and purpose. Even if you haven’t tracked all year, start now and estimate conservatively for the past months if you have records.

Mistake 3: Mixing Personal and Business Expenses

Using the same credit card for personal and business purchases is a recipe for an audit. It also makes it nearly impossible to claim legitimate deductions without spending hours sorting receipts.

What to do this week: Open a separate business credit card and bank account. Move all business transactions to them. Going forward, pay for every business expense from that card. If you’ve already mixed expenses, work with your bookkeeper to separate them now.

Mistake 4: Overlooking Deductible Supplies and Equipment

Plastic surgery practices use expensive supplies: implants, sutures, bandages, and more. You can deduct the cost of supplies used in procedures, and you can deduct or depreciate equipment like lasers and surgical tables. Many new owners forget to track these expenses.

What to do this week: Review your purchase receipts for the year. Categorize everything: supplies (deductible in full), equipment (depreciate over 5-7 years, or use Section 179 to deduct up to $1,220,000 in 2026). If you bought equipment, ask your CPA about bonus depreciation.

Mistake 5: Forgetting Quarterly Estimated Taxes

If you’re self-employed or an S-corp owner, you must pay estimated taxes quarterly. Missing a payment leads to penalties and interest. Many new practice owners don’t realize this until tax time.

What to do this week: Check the IRS due dates for 2026: April 15, June 15, September 15, and January 15, 2027. If you missed a payment, pay it now to minimize penalties. Calculate your estimated tax using Form 1040-ES, or ask your CPA to do it.

Mistake 6: Not Hiring a Professional for Tax Preparation

DIY tax software might work for a simple return, but a plastic surgery practice is not simple. You have inventory, depreciation, payroll, and possibly multiple states. A mistake can trigger an audit or cost you thousands in missed deductions.

What to do this week: Interview at least three CPAs who specialize in medical practices. Ask about their experience with plastic surgery. Fees range from $1,500 to $5,000 for a practice return. That’s a fraction of what you’ll save in deductions and avoided penalties.

Mistake 7: Ignoring State and Local Tax Obligations

Beyond federal taxes, you have state income tax, sales tax on retail items (like skincare products), and possibly local business taxes. New owners often overlook these, leading to surprise bills and penalties.

What to do this week: Check your state’s department of revenue website. Register for sales tax if you sell retail products. Find out if you need a business license or pay a gross receipts tax. Your CPA can help you identify all obligations.

FAQ

Can I deduct the cost of my medical license and board certification?

Yes, you can deduct the cost of renewing your medical license and board certification as a business expense. Initial certification costs may need to be amortized over its useful life, but renewals are fully deductible.

What is the best business structure for a plastic surgery practice?

Most practices benefit from an S-corp or LLC taxed as an S-corp. It limits liability and can save on self-employment taxes. However, the best choice depends on your specific situation. Consult a CPA.

How much should I set aside for taxes each month?

A good rule of thumb is 25-30% of your net income for federal and state taxes, plus self-employment tax. If you’re an S-corp, you’ll also have payroll taxes. Your CPA can give you a more precise number.

What if I miss a quarterly estimated tax payment?

Pay it as soon as possible. The penalty is based on how late the payment is, so paying sooner reduces the penalty. You can also adjust your withholding or next estimated payment to catch up.

The bottom line

Your first year is about building a solid foundation. Avoiding these tax mistakes will save you money and stress. Start with the basics: separate accounts, track mileage, and hire a CPA who knows medical practices. Take one action this week, and then the next. Your future self will thank you at tax time.
