Forming an S corporation for your therapy practice comes with many benefits. But if it’s your first year filing taxes with S corporation status, it’s easy to feel a bit lost.

Check off the applicable items below and track everything you need for you or your accountant to file taxes for your S corporation.


Basic Information

  • Your full legal name and date of birth
  • Your social security number (SSN)
  • Your S-corp’s Employer Identification Number (EIN), documented on your SS-4 Letter from the IRS
  • Last year’s tax return
  • Last year’s total adjusted gross income
  • Your IRS Self-Select Pin from last year’s filing
  • Total amount paid in quarterly taxes during 2022
  • Bank account information: account and routing numbers

Tax Forms 

  • Form 1120-S (S corporation tax return)
  • Form 2553 (Election by a Small Business Corporation)
  • Form SS-4 or EIN Letter from the IRS
  • Form W-2 (for the salary you pay yourself as an employee, and for any other salaries paid to other employees of your S-corp) 
  • Schedule K-1 (issued to you, as the shareholder, to report your share of S corporation income, losses, and dividends to be reported on your 1040)
  • Form 1099 (if your S-corp paid for a contractor’s services during the year)

Financial Statements

  • Annual profit and loss (P&L) statement

Receipts and Financial Records

  • Advertising and marketing 
  • Accounting and bookkeeping services
  • Business meals
  • Business trips
  • Bank fees
  • Vehicle use (mileage rate or actual expenses)
  • Membership fees
  • Continuing education
  • Office rent (including home office)
  • Office supplies
  • Books and therapeutic aids
  • Personal therapy
  • Square, Stripe, and other payment processor fees
  • Booking and billing software

You or your accountant will use these to add up all your tax deductible expenses for the year. They must be kept after you file taxes, to back up your claims in the event of an IRS audit.
