Working as an independent contractor gives you freedom. You choose your offices, set your schedule and often earn more per day than an employee. But that first April as a 1099 dentist can be a shock. No taxes were withheld, self-employment tax takes a big bite, and suddenly you owe a lot more than you expected.
The right dental accounting services can turn that stress into a simple, predictable plan. Whether you’re an associate, a locum dentist or a hygienist working across several practices, here’s what you need to know.
What Do Dental Accounting Services Include?
Dental accounting services go well beyond filing a tax return. For contractors, a good firm will typically help with:
- Calculating and scheduling quarterly estimated tax payments
- Tracking business expenses and mileage throughout the year
- Setting up a retirement plan that fits a self-employed income
- Advising on whether an LLC or S corporation makes sense
- Reviewing contracts so you understand how and when you’re paid
Dental Contractors Tax Planning: The 1099 Reality
Self-employment tax is the big surprise
As an employee, your employer pays half of your Social Security and Medicare taxes. As a contractor, you pay both halves. That’s 15.3% on net earnings up to $184,500 in 2026, plus 2.9% for Medicare on everything above that.
For example, a contractor dentist netting $180,000 could owe over $25,000 in self-employment tax alone, before any income tax.
Quarterly estimates are not optional
The IRS expects you to pay as you go. Estimated payments are usually due April 15, June 15, September 15 and January 15. Miss them and you’ll face underpayment penalties.
A simple safe harbor helps. If you pay at least 100% of last year’s total tax through estimates, or 110% if your prior-year income was over $150,000, you generally avoid penalties, even if you owe more at filing time.
Are you really a contractor?
The IRS looks at who controls the work. If a practice sets your hours, provides all your supplies and directs how you treat patients, you might legally be an employee. Getting this wrong can create problems for you and the practice, so it’s worth a review.
Smart Moves in Dental Contractors Tax Planning
Claim every business deduction
As a contractor, you can deduct the costs of doing your job. Common examples include:
- Malpractice insurance
- Loupes, headlamps and personal instruments
- License renewals, DEA registration and professional dues
- Continuing education courses
- Mileage between practices, at 72.5 cents per mile in 2026
Driving from home to your regular office is commuting and isn’t deductible. Driving from one office to another during the day usually is.
Open a solo 401(k)
A solo 401(k) is one of the best tools for contractors. In 2026, you can defer $24,500 as the employee, plus an employer contribution of roughly 20% of net self-employment earnings, up to $72,000 in total. Those contributions cut your income tax bill directly.
Consider an S corporation
Once your net income is consistently strong, an S corporation can reduce self-employment tax. You pay yourself a reasonable salary and take the rest as distributions. The extra payroll and filing costs mean it isn’t right for everyone, so run the numbers first.
Why Practice Owners Need This Too
If you own a practice that hires contractors, dental contractors tax planning affects you as well. You’ll need to issue Form 1099-NEC to each contractor by January 31 and make sure every arrangement truly meets contractor rules. Misclassifying an employee can lead to back payroll taxes and penalties.
Contracting can be a great path for dentists and hygienists, but it brings tax responsibilities that employees never see. With the right dental accounting services, you can plan your estimates, claim every deduction and build retirement savings, so April feels routine instead of frightening.
