What Do Therapists Need to Know About Taxes in Indiana?

Indiana has a flat state income tax and relatively simple compliance rules — but you still need a solid tax setup to avoid overpaying and missing deadlines. This guide walks therapists in Indiana through entity options, deductions, and how to stay tax-ready year-round.


Who this guide is for

This guide is for:

  • Licensed Indiana therapists (LMHCs, LCSWs, LMFTs, psychologists, etc.)
  • Solo practitioners, group practice owners, and contractors
  • Therapists providing in-person, virtual, or hybrid services
  • Clinicians who want to avoid penalties and keep more of their income

Step 1: Pick the right structure for your practice

Your structure affects how you're taxed, how you pay yourself, and what paperwork you deal with.

Sole Proprietorship

  • No state registration required unless you use a trade name (DBA)
  • All profits taxed as personal income
  • Easiest to manage, but no liability protection

PLLC (Professional LLC)

  • Indiana allows licensed professionals to form PLLCs
  • Provides personal liability protection
  • Default tax status: pass-through (like sole prop)
  • Can elect S Corp status to reduce self-employment tax
  • Register with Indiana Secretary of State + notify licensing board

S Corporation

  • Allows you to split income between salary and distributions
  • Cuts self-employment tax, but adds complexity (payroll, extra filings)
  • Becomes worthwhile when net income exceeds ~$75K
  • Still subject to Indiana state income tax

Professional Corporation (PC)

  • Permitted in Indiana
  • More admin required — better suited for groups
  • Can be taxed as an S Corp if elected

Step 2: Know your state tax obligations

State income tax

  • Indiana has a flat income tax rate of 3.15% for 2025
  • All personal and pass-through income is taxed at this rate
  • File using Form IT-40 (residents) or IT-40PNR (non-residents)

County income tax

  • Indiana counties charge additional income tax on top of the state rate
  • Rates vary by county (typically 1–3%)
  • Your tax return automatically calculates this based on your residence

Annual business entity report

  • Required for PLLCs and PCs
  • Due every other year
  • $50 filing fee
  • File via Indiana INBiz portal

Business license

  • Indiana doesn’t require a statewide license for therapists
  • Local cities or counties may have zoning or permit rules

Step 3: Pay taxes throughout the year — not just in April

Estimated taxes

  • Required if you expect to owe $1,000+ in state or federal taxes
  • Due: April 15, June 15, Sept 15, Jan 15
  • Use Form ES-40 or pay online for Indiana

Self-employment tax

  • Applies to net income from sole props and default PLLCs
  • 15.3% for Social Security and Medicare
  • S Corp helps lower this tax burden

Filing requirements

  • Sole prop: Schedule C + Indiana IT-40
  • PLLC: Biennial report + IT-40 + federal taxes
  • S Corp: 1120-S + Indiana IT-20S + payroll + state/county income tax

Step 4: Track and claim your deductions

Deductions matter — especially for federal tax savings.

Deductible expenses for therapists

  • EHR, scheduling, and telehealth platforms
  • License renewals, CEUs, supervision
  • Rent or home office
  • Malpractice insurance
  • Phone, internet, admin tools
  • Marketing and directories
  • Retirement plan contributions
  • Self-employed health insurance

Step 5: When it’s time to consider an S Corp

The S Corp structure helps reduce taxes — if you're earning enough to justify the extra work.

  • Pay yourself a reasonable salary
  • Take remaining profits as distributions
  • Avoid self-employment tax on the distribution portion
  • Still pay Indiana state and county income tax on all income
  • Must run payroll and file corporate returns

Step 6: Common mistakes therapists make

  • Ignoring county income tax and underpaying
  • Forgetting the biennial report for PLLCs
  • Waiting too long to elect S Corp
  • Not filing estimated taxes
  • Skipping deductions for CEUs, rent, and software
  • Using personal accounts for business expenses
