7 Mistakes New Ot Practices Make in Their First Year
Avoid common tax pitfalls in your first year of OT practice. Learn the 7 mistakes and how to fix them with practical steps and realistic figures.
Starting an occupational therapy (OT) practice is exciting, but the first year brings a steep learning curve, especially around taxes. Many new owners make avoidable mistakes that cost them time, money, and stress. Here are the 7 most common tax mistakes new OT practices make, and how to avoid them.
Mistake 1: Choosing the Wrong Business Structure
Many new OT owners start as sole proprietors without realizing the tax and liability implications. A sole proprietorship means you report business income on your personal return (Schedule C), and you pay self-employment tax on all net earnings. In 2026, the self-employment tax rate is 15.3% (12.4% for Social Security, 2.9% for Medicare).
What to do instead: Consider an S-corporation or LLC. An LLC offers liability protection, but you still pay self-employment tax unless you elect S-corp status. With an S-corp, you pay yourself a reasonable salary (subject to payroll taxes) and take the rest as distributions, which are not subject to self-employment tax. For many OT practices, this can save $3,000 to $8,000 per year in taxes. However, S-corps require payroll processing and extra paperwork, so weigh the costs. Consult a CPA to determine the best structure for your situation.
Mistake 2: Not Tracking Expenses from Day One
New practice owners often mix personal and business expenses, or they forget to log small purchases. Every deductible expense you miss is money you overpay in taxes. Common deductible expenses for OT practices include: rent, utilities, equipment, supplies, professional liability insurance, continuing education, marketing, and software subscriptions.
What to do instead: Open a separate business bank account and credit card immediately. Use accounting software like QuickBooks or Xero to track expenses. Set aside 15 minutes each week to categorize transactions. Keep all receipts, either digitally (using apps like Expensify) or in a folder. If you use your car for business, track mileage with a log or app; the 2026 IRS standard mileage rate is 67 cents per mile.
Mistake 3: Ignoring Quarterly Estimated Taxes
If you expect to owe more than $1,000 in taxes, the IRS requires you to pay estimated taxes quarterly. Many new owners miss these deadlines and face penalties. The due dates are April 15, June 15, September 15, and January 15 (for the prior year). In 2026, the underpayment penalty is about 7% of the amount owed, plus interest.
What to do instead: Estimate your annual income and calculate your quarterly payments. A common approach is to pay 25% of your expected annual tax liability each quarter. Use IRS Form 1040-ES. If your income is variable, consider the annualized installment method to avoid overpaying early. Set reminders for the deadlines, and pay online via the IRS Direct Pay system.
Mistake 4: Misclassifying Employees as Independent Contractors
OT practices often hire contract therapists or administrative staff. Misclassifying employees as independent contractors can lead to back taxes, penalties, and legal issues. The IRS uses a 20-factor test to determine worker status, focusing on behavioral control, financial control, and the type of relationship.
What to do instead: If you control when, where, and how the work is done, the worker is likely an employee. If you hire contractors, ensure they have their own insurance, set their own hours, and work for other clients. Use a written contract. When in doubt, file Form SS-8 with the IRS for a determination, or consult an employment attorney.
Mistake 5: Not Taking Advantage of Retirement Tax Credits
New practice owners often skip retirement plans because they think they can’t afford them. But there are tax credits available. The Saver’s Credit (for individuals) and the Retirement Plan Startup Costs Credit (for small businesses) can offset costs. In 2026, the startup credit covers 50% of eligible plan costs, up to $5,000 per year for the first three years.
What to do instead: Consider a SEP IRA or a Solo 401(k). With a SEP IRA, you can contribute up to 25% of your net earnings, up to $69,000 in 2026. A Solo 401(k) allows employee and employer contributions, with a total limit of $69,000 (plus catch-up if over 50). These contributions reduce your taxable income. Set up a plan before December 31 to claim the credit for that tax year.
Mistake 6: Overlooking Home Office Deduction
If you run your OT practice from home, you can deduct expenses for the space used exclusively and regularly for business. Many owners miss this deduction because they think it’s a red flag for audits. But it’s a legitimate deduction if you meet the requirements.
What to do instead: Use the simplified method: deduct $5 per square foot of home office space, up to 300 square feet, for a maximum deduction of $1,500. Or use the actual expense method: calculate the percentage of your home used for business and apply that to mortgage interest, utilities, insurance, and repairs. Keep a record of your home office dimensions and usage. Ensure the space is used only for business, not as a guest room or storage.
Mistake 7: Failing to Plan for State and Local Taxes
Federal taxes get most of the attention, but state and local taxes can be significant. Some states have income taxes, and many cities impose a gross receipts tax on businesses. For example, in California, the state income tax rate can be up to 13.3%, and there’s an $800 minimum franchise tax for LLCs. In Texas, there’s a franchise tax based on revenue.
What to do instead: Research your state’s tax requirements for OT practices. Check if you need a sales tax permit (though services are often exempt). Register with your state’s department of revenue. Set aside a percentage of income for state taxes, typically 5% to 10%. If you have employees, you must also handle state unemployment insurance and payroll taxes.
FAQ
Q: When should I start paying estimated taxes? A: As soon as you expect to owe more than $1,000 in taxes. If you’re starting mid-year, you may need to pay your first quarter’s estimated tax within a few weeks of starting. Use Form 1040-ES and pay online.
Q: Can I deduct expenses for my home office if I also see patients there? A: Yes, if the space is used exclusively and regularly for business. If you see patients in that space, it’s still deductible, but you must meet the exclusive use test. Keep records of patient visits and the space’s use.
Q: What is the penalty for missing a quarterly estimated tax payment? A: The penalty is generally 0.5% of the unpaid amount for each month it’s late, up to 25%. Plus interest. In 2026, the interest rate is around 7% per year, compounded daily.
Q: Should I hire a CPA for my first year? A: Yes, especially if you’re not familiar with tax laws. A CPA can help you choose the right structure, set up bookkeeping, and plan for taxes. Fees range from $150 to $400 per hour, or $1,000 to $3,000 for annual preparation and planning.
