The New Pt Practice Tax Calendar: Every Deadline You Cannot Miss
A practical 2026 tax deadline calendar for new physical therapy practices, with monthly action steps and estimated costs.
Starting a physical therapy practice means taking on a new set of responsibilities, and taxes are among the most critical. Missing a deadline can trigger penalties, interest, and unnecessary stress. This guide provides a clear, month-by-month calendar for 2026, tailored to new PT practices. You will know exactly what to file, when, and what it might cost if you miss a date.
Why a Tax Calendar Matters for Your PT Practice
The IRS does not extend deadlines for new businesses. Even if you have no income yet, you may still need to file. For a typical new PT practice, the first year involves estimated quarterly payments, payroll taxes, and annual reports. Missing a single deadline can cost you 5% of the unpaid tax per month for late filing, plus interest. A simple calendar keeps you compliant and avoids surprises.
The 2026 Tax Calendar at a Glance
Below is a month-by-month breakdown of key deadlines. Dates are based on standard IRS rules. If a date falls on a weekend or holiday, the deadline moves to the next business day.
| Month | Key Deadlines | What to Do |
|---|---|---|
| January | January 15: Q4 estimated tax payment (for prior year) | Pay any remaining estimated tax for 2025. |
| February | February 2: File W-2s and 1099-NECs with the IRS | Send copies to employees and contractors. |
| March | March 16: S-corp or partnership tax return (1120-S or 1065) | File or request an extension (Form 7004). |
| April | April 15: Individual tax return (1040) and Q1 estimated payment | File your personal return and pay Q1 estimate. |
| June | June 15: Q2 estimated tax payment | Pay if you expect to owe $1,000 or more. |
| September | September 15: Q3 estimated tax payment | Pay your third-quarter estimate. |
| October | October 15: Extended individual return due | File if you requested an extension in April. |
| December | December 15: Corporate extension deadline (C-corp) | File if you have a C-corp extension. |
Note: If you are a sole proprietor or single-member LLC, you report practice income on your personal return (Schedule C). If you formed an S-corp or partnership, you have separate filing requirements.
Monthly Action Steps for New PT Practices
January: Set Up Your Accounting System
If you have not already, choose accounting software (QuickBooks, Xero, or FreshBooks) and set up a separate business bank account. This month, you should also review your 2025 income and pay any Q4 estimated tax by January 15. If you are new, you may not have a payment due, but you still need to track expenses.
February: File Information Returns
By February 2, you must file W-2s for employees and 1099-NECs for independent contractors (if you paid them $600 or more). The penalty for missing this is $60 per form, up to $630,000 for small businesses. Use e-file to reduce errors.
March: Business Entity Returns
If your practice is an S-corp or partnership, your tax return is due March 16. If you cannot file, submit Form 7004 to get a six-month extension. Note: an extension to file is not an extension to pay. You must estimate and pay any tax due by the original deadline.
April: Personal and Estimated Taxes
April 15 is the big one: your personal tax return (Form 1040) and your first quarterly estimated payment for 2026. For a new PT practice, your estimated payment is based on your projected profit. A common method is to pay 100% of last year’s tax liability (or 110% if your income is over $150,000). If you are just starting, you may pay based on 90% of current-year tax, but that can lead to underpayment penalties if you are off.
May: Review and Reconcile
Use this month to reconcile your bank statements with your accounting software. Check that all 1099s and W-2s match your records. If you have employees, ensure payroll taxes are being deposited correctly. The IRS requires semi-weekly or monthly deposits, depending on your payroll size.
June: Q2 Estimated Payment
June 15 is the deadline for your second quarterly payment. If your income is uneven, you can annualize your income using Form 2210 to lower your payment, but that requires calculation. Most new practices simply pay a fixed amount each quarter.
July: Mid-Year Check
By July, you should have a clear picture of your first half. Review your profit and loss statement. If you are ahead of projections, consider increasing your Q3 payment to avoid a big bill in April. Also, check if you need to file any state or local taxes, such as sales tax if you sell products like braces or therapeutic tape.
August: Prepare for Q3
No major federal deadlines in August, but use this time to organize your receipts and mileage logs. If you use a vehicle for home visits or business errands, track your mileage. The standard mileage rate for 2026 is expected to be around $0.70 per mile (the 2025 rate is $0.70, so it may adjust slightly).
September: Q3 Estimated Payment
September 15 is your third quarterly payment. By now, you should have a good idea of your annual income. If you are underpaying, adjust now. The IRS charges a penalty for underpayment of estimated tax, which is currently around 8% per year, compounded daily.
October: Extended Returns and Planning
If you filed an extension in April, your personal return is due October 15. Also, start thinking about year-end tax strategies. For example, you can contribute to a SEP IRA or solo 401(k) to reduce taxable income. The deadline for these contributions is your tax filing deadline, including extensions.
November: Year-End Prep
Begin gathering documents for your accountant. This includes all income statements, expense receipts, and any 1099s you received. Also, consider purchasing equipment before December 31 to take advantage of Section 179 or bonus depreciation, which can deduct up to $1,220,000 (2026 limit) for qualifying property.
December: Final Payments and Deadlines
If you are a C-corp, your extended return is due December 15. For most PT practices, December is about making sure you have paid enough in estimated taxes. If you are short, you can make a fourth-quarter payment by January 15 of the next year, but that is technically for Q4. Also, review your payroll to ensure all deposits are current.
Common Tax Mistakes New PT Practices Make
- Mixing personal and business expenses: This complicates deductions and can trigger audits. Use a separate credit card for business.
- Forgetting quarterly payments: Many new owners assume they will owe nothing in year one, but if you profit, you must pay as you go.
- Missing contractor forms: If you hire a locum tenens PT or a billing contractor, you must issue a 1099-NEC by January 31.
- Ignoring state taxes: Your state may have its own estimated payment deadlines, often aligned with federal dates but not always. Check your state’s department of revenue.
FAQ
Do I need to pay estimated taxes in my first year?
Yes, if you expect to owe $1,000 or more in tax. You can use the annualized method if your income is uneven, but the safest approach is to pay quarterly based on your projected profit.
What if I miss a deadline?
You will face penalties and interest. The late filing penalty is 5% of the unpaid tax per month, up to 25%. The late payment penalty is 0.5% per month. File as soon as possible to minimize damage.
Can I file an extension for my business tax return?
Yes, you can file Form 7004 for an automatic six-month extension for most business returns. However, this does not extend the time to pay any tax due. You must estimate and pay by the original deadline.
How much should I set aside for taxes?
A common rule is to set aside 25% to 30% of your net profit for federal taxes, plus state taxes if applicable. For a PT practice, your effective rate may be lower if you have deductions, but it is safer to overestimate.
The Bottom Line
Running a new PT practice requires discipline, and taxes are a year-round task. Use this calendar to mark your deadlines, set reminders, and work with a CPA who understands small practices. By staying organized, you avoid penalties and keep more of your hard-earned revenue. Start this week: set up your accounting system, note the next deadline, and schedule a check-in with your tax professional.
