Top Tax Deductions for Dental Practice Business Owners

14 Key write-offs for Dental Practice Business Owners

Practical deductions and tax-saving strategies

When you run a dental practice, more is needed than patient care — you have to stay on top of your finances if you want to keep profit margins up and be able to shield taxable income. Knowing which costs are deductible, and how to document them, can be a huge money saver every year. In this guide to the most important tax deductions for dental practice business owners, we offer actionable tips on ways to benefit the most from them, while also remaining audit-ready.

Ordinary and Necessary Business Expenses

Under most common deductions, the costs must be ordinary (common in the trade) and necessary (helpful and appropriate). For a dental office this would be rent, utilities, (paper) office supplies, (clinical) supplies, lab fees and pro fees. Keep a close eye on these costs, apportioning shared expenses (for example utilities) between clinical and administrative.

Wages, Payroll Taxes, and Benefits for Employees

You can also deduct the salaries and wages of hygienists, dental assistants, office staff and receptionists. Payroll taxes paid by employers, workers’ compensation and contributions to employee benefit programs (such as group health plans) also reduce taxable income. Providing employees with qualified retirement plans not only attracts and retains them, you can obtain deductible employer contributions.

Equipment Purchases and Depreciation

Dental chairs, X-ray units, CAD/CAM units and other capital expenditures are generally paid for out of depreciation. Depending on cost, the tax year and whether or not you meet certain requirements, some purchases may be eligible for accelerated expense recovery methods that allow you to deduct more of a purchase sooner. Small tools and qualifying assets may be able to take a deduction in the year of purchase under bonus depreciation or expensing rules. Keep receipts and serial numbers, and mark placed-in-service dates.

Dental Supplies and Lab Fees

Consumables such as impression materials, gloves, and bonding agents or lab fees for crowns or prosthetics are all normal costs. These can be – and usually are – 100% deductible in the year of purchase, as they directly relate to delivering care. Keep the receipts you receive from vendors and attach an expenditure to patient services or inventory records, if applicable.

Rent, Utilities, and Facility Costs

Regardless of whether you rent or own your office, some costs help lower your taxable income. Rent for clinic space, cost of building upkeep and maintenance, property management fees and utilities ( electricity, water and HVAC servicing) all can be deducted under their respective categories. If you work out of a multi-use office, divide shared costs (such as rent) according to square footage, or another fair standard.

Professional Fees and Continuing Education

Fees paid to accounting, legal, and other consultants that are applicable to the practice are deductible. Ongoing education for dentists and staff that preserves or enhances professional skills is also eligible. Document course descriptions and dates, as well as how the training affects practice operations.

Insurance Premiums

Business expenses such as professional liability, business property and other policies related to the practice are disposable for deduction. Health Insurance Premiums Pretax for Employees When paid by the practice, are also deductible under Employee Benefit Programs.

Interest on loans taken for Business.

Business loan interest, lines of credit used for practice operations and certain types of credit cards associated with practice expenses may be deductible. Different rules exist for interest on loans that are secured by personal assets or used in a non-business manner, so document the loan proceeds and their application clearly.

Advertising and Marketing

Marketing your practice Your patient acquisition costs, including advertising and website administration; patient referral program costs; and costs for holding community outreach events, are usually tax deductile. Differentiate between marketing expenses and personal or non-business promotional costs.

Travel, Meals, and Entertainment

When done primarily for business, such as conferences, supplier visits or continuing education, business travel is also deductible. Meals during business travel or at a qualifying business meeting may be only partially deductible; record the business purpose, individuals present and location. Entertainment is far more limited, so emphasize the business connection.

Retirement Plan Contributions

Contributions to qualified retirement plans for both for owners and employees can help to lower taxable income as well as accumulate long-term savings. Options range based on the size of the practice and goals — but setting a plan before year’s end could open doors to substantial deductible contributions.

Start-up and Organizational Costs

Amortization of some startup and organizational expenses is also permitted during a specified period (such as 60 months) or may be partially expensed in the first year, if you’re new to the practice business. Find out the optimal tax treatment for track pre-opening expenses such as professional fees, training and office build-out.

Bad Debts and Accounts Receivable

Under the accrual method of accounting, you may be able to claim a deduction for bad debts when patient accounts prove uncollectible. Bad debt deductions are generally restricted for tax purposes of the cash-basis taxpayer, i.e., income is not ascertainable until received. Maintain accurate collection records and adequate documentation of collections activity.

Home Office and Mixed-Use Deductions

If you regularly and exclusively use part of your home as business office space or for regular patient coordination activities, you may be able to take a home office deduction. This deduction depends on a good estimate of space used, such as the number of square feet in the home and apportionment of mortgage interest, utilities and insurance.

Documentation Best Practices

Solid recordkeeping turns potential deductions into real tax savings you can count on. Keep detailed file records of your invoices, receipts, payroll statements, bank statements and contracts. Adopt uniform naming and dating practices, and again scan underlying documents to have digital backups at all times. For deductions connected to business use (like vehicles, home office or travel), logs and explanations of the business purpose from the same time period are especially effective.

Timing and Tax Planning

Make spending, equipment additions, or retirement plan contributions just before year-end count against this year’s income. Work with your accountant to determine taxable consequence and whether or not you want to expense versus capitalize some items.

Preparing for an Audit

In audit, documentation is the best defense. Maintain detailed records that demonstrate the business reason for expenses and how each deduction relates to practice operations. Have consistent accounting policies and be able to justify the way in which shared costs are being allocated.

Conclusion

When they are used thoughtfully and documented appropriately, tax deductions can have a meaningful impact on a practice’s bottom line. Focus on good record keeping, work with a tax professional on complex issues and take year-end planning seriously to mitigate any available deductions. By taking the right approach, dental practice owners can lower their tax obligation and reinvest in the staff, equipment and services they need to build upon.
