The New Speech Therapy Practice Tax Calendar: Every Deadline You Cannot Miss

A practical 2026 tax deadline calendar for new speech therapy practices, with quarterly dates, filing tips, and penalty avoidance strategies.
Starting a speech therapy practice means taking on the business side of things, and taxes are a big part of that. Missing a deadline can cost you penalties and interest, which is money you could use for equipment or marketing. This guide gives you the exact dates you need to mark on your calendar for 2026, plus steps to stay organized and avoid common mistakes.
Why a Tax Calendar Matters for Your Practice
As a new practice, you are likely a sole proprietor, LLC, or S-corp, and the IRS expects estimated tax payments throughout the year, not just on April 15. If you owe more than $1,000 at filing time, you may face an underpayment penalty. A tax calendar keeps you ahead of deadlines, helps you plan cash flow, and ensures you don’t miss quarterly deposits for payroll if you have employees.
Key 2026 Tax Deadlines for Speech Therapy Practices
The IRS sets specific dates for estimated payments, payroll taxes, and annual filings. Here is the full schedule for 2026:
Estimated Tax Payment Deadlines (Quarterly)
If you are a sole proprietor, LLC, or S-corp, you pay estimated taxes on income not subject to withholding. These are due four times a year:
- Q1 (Jan 1 to Mar 31): Due April 15, 2026
- Q2 (Apr 1 to May 31): Due June 15, 2026
- Q3 (Jun 1 to Aug 31): Due September 15, 2026
- Q4 (Sep 1 to Dec 31): Due January 15, 2027
Use IRS Form 1040-ES to calculate and pay. You can pay online via the IRS Direct Pay system, which is free and gives you instant confirmation.
Payroll Tax Deadlines (If You Have Employees)
If you hire staff, you must withhold Social Security, Medicare, and income taxes. These are typically due monthly or semi-weekly, depending on your payroll size. For most small practices, monthly deposits are due by the 15th of the following month. For example, January payroll taxes are due February 15, 2026. You also need to file Form 941 quarterly:
- Q1 (Jan-Mar): Due April 30, 2026
- Q2 (Apr-Jun): Due July 31, 2026
- Q3 (Jul-Sep): Due October 31, 2026
- Q4 (Oct-Dec): Due January 31, 2027
Annual Filing Deadlines
- Form 1065 (Partnership): Due March 16, 2026 (if you have a partner)
- Form 1120-S (S-Corp): Due March 16, 2026 (if you elected S-corp status)
- Form 1040 (Sole Proprietor): Due April 15, 2026
- Form 1099-NEC (Independent Contractors): Must be sent to contractors by January 31, 2026, and filed with the IRS by that date.
- Form 940 (Federal Unemployment Tax): Due January 31, 2026, if you have employees.
How to Calculate Your Estimated Payments
Your estimated payment is based on your expected adjusted gross income, taxable income, taxes, and credits. A simple method: take your previous year’s tax liability (if you had any) and divide by 4. For a new practice, estimate your net income for the year, multiply by your effective tax rate (usually 25% to 30% for federal, plus state), and divide by 4. For example, if you expect $80,000 in net profit, federal taxes might be around $16,000, so each quarterly payment would be $4,000. Adjust if your income fluctuates.
What Happens If You Miss a Deadline?
Missing a deadline triggers penalties and interest. The IRS charges a failure-to-pay penalty of 0.5% of the unpaid amount per month, up to 25%. Interest accrues on the unpaid balance. For example, if you miss a $2,000 payment by 3 months, you could owe around $30 in penalties plus interest. It adds up, so set reminders.
Tools and Resources to Stay on Track
Use these tools to manage your calendar:
- IRS Direct Pay: Free online payment system for estimated taxes.
- Accounting software: QuickBooks or Xero can track income, expenses, and remind you of deadlines. Costs range from $30 to $100 per month.
- Tax professional: A CPA or enrolled agent can handle filings and advise on deductions. Fees vary from $200 to $500 for a basic return, or $100 to $200 per hour for ongoing advice.
- Calendar apps: Set recurring reminders on Google Calendar or Outlook for each deadline.
Common Tax Deductions for Speech Therapy Practices
To lower your taxable income, track these deductions:
- Home office: If you use a dedicated space, you can deduct $5 per square foot up to 300 square feet (simplified method).
- Equipment and supplies: Therapy tools, assessment materials, and office supplies.
- Professional development: Continuing education courses and conferences.
- Software subscriptions: Scheduling, billing, and documentation tools.
- Marketing: Website, business cards, and online ads.
- Vehicle expenses: If you travel to see clients, use the standard mileage rate (67 cents per mile in 2026) or actual expenses.

FAQ
Do I need to pay estimated taxes in my first year?
Yes, if you expect to owe $1,000 or more. You can use the annualized income installment method if your income is uneven, but the standard method is simpler.
Can I deduct health insurance premiums?
Yes, if you are self-employed, you can deduct premiums for yourself, your spouse, and dependents, as long as you are not eligible for an employer-sponsored plan.
What if I miss a deadline?
Pay as soon as possible to minimize penalties. The IRS may waive penalties if you show reasonable cause, but it’s not guaranteed. Contact a tax professional for help.
Should I hire a CPA or use tax software?
For a new practice, a CPA can save you money by identifying deductions and ensuring compliance. Software like TurboTax or TaxAct costs $50 to $150, but a CPA may cost $300 to $600 for a business return. Consider your complexity.
The Bottom Line
Your tax calendar is not optional; it’s a core part of running a profitable speech therapy practice. Mark every deadline, set reminders, and consider using a professional for your first year. Missing a payment costs you money, but staying organized saves you stress and cash. Start today by writing down the next quarterly deadline and setting a reminder on your phone.
If you have employees, add payroll deadlines to your calendar. If you are a sole proprietor, focus on the quarterly estimated payments. With this guide, you have everything you need to stay compliant and keep more of your hard-earned revenue.
