What Do Therapists Need to Know About Taxes in Mississippi?

Mississippi’s income tax is relatively straightforward — but many therapists overlook entity rules, annual filings, and the state’s unique gross income thresholds. This guide breaks down exactly what you need to know to run a compliant, tax-smart private practice in Mississippi.


Who this guide is for

This resource is built for:

  • Licensed Mississippi therapists (LPCs, LCSWs, LMFTs, psychologists, etc.)
  • Solo practice owners and group practice leaders
  • Therapists providing telehealth, in-person, or hybrid services
  • Professionals who want to reduce their tax burden and avoid state-level surprises

Step 1: Pick the right structure for your practice

The structure you choose determines how you’re taxed and what your filing responsibilities look like.

Sole Proprietorship

  • Easiest to set up — no formal registration required
  • No liability protection
  • All income is taxed on your personal return
  • Must register a DBA if using a trade name

PLLC (Professional LLC)

  • Mississippi allows licensed professionals to form PLLCs
  • Offers liability protection
  • Default tax treatment: pass-through
  • Can elect S Corp status with the IRS for tax savings
  • File with the Mississippi Secretary of State

S Corporation

  • Helps reduce self-employment tax
  • Requires W-2 payroll, bookkeeping, and separate filings
  • Makes sense once your practice nets ~$75K or more annually
  • Must file a Mississippi S Corp return and federal 1120-S

Professional Corporation (PC)

  • Also allowed in Mississippi
  • Can elect S Corp status
  • Requires more formalities — generally better for multi-owner practices

Step 2: Know your state tax obligations

State income tax

  • Mississippi has graduated income tax brackets:
    • 0% on the first $5,000 of taxable income
    • 4.7% on income $5,001–$10,000
    • 5% on income over $10,000
  • Applies to pass-through business income
  • File with Form 80-105 (individual return)

Annual report

  • Required for PLLCs and PCs
  • Due April 15 each year
  • File through the Mississippi Secretary of State website
  • No filing fee for PLLCs; $25 fee for corporations

Business registration

  • Must register your business through the Secretary of State
  • If operating under a trade name, you must also file a fictitious name registration

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

Estimated taxes

  • Required if you expect to owe $200+ in state tax or $1,000+ to the IRS
  • Due quarterly: April 15, June 15, Sept 15, Jan 15
  • File with Form 80-106 or pay online

Self-employment tax

  • 15.3% applies to all net income from sole props and default PLLCs
  • Can be reduced with an S Corp structure — if you run proper payroll

Filing requirements

  • Sole prop: Schedule C + MS Form 80-105
  • PLLC: MS Form 80-105 + annual report + federal tax return
  • S Corp: Federal 1120-S + MS Form 83-310 (Mississippi S Corp return) + payroll + annual report

Step 4: Track and claim your deductions

You only pay tax on your net income — so make sure you’re tracking everything that counts.

Deductible expenses for therapists

  • Rent, coworking, or home office
  • CEUs, license renewals, supervision
  • Malpractice and liability insurance
  • Therapy platforms, EHRs, scheduling systems
  • Marketing, directories, business cards
  • Internet, phone, supplies
  • Self-employed health insurance
  • Retirement plans (Solo 401k, SEP IRA)

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

If your practice is bringing in more than $75K after expenses, an S Corp could help reduce your tax burden.

  • Pay yourself a reasonable W-2 salary
  • Take the rest of your profit as distributions
  • Avoid self-employment tax on distributions
  • Must manage payroll and file a separate MS corporate return

Step 6: Common mistakes therapists make

  • Missing the April 15 annual report deadline
  • Not registering their trade name (DBA)
  • Underestimating state tax on pass-through income
  • Not making quarterly estimated payments
  • Skipping deductions like CEUs, marketing, or insurance
  • Choosing a structure (like PC or PLLC) but not maintaining it properly

Step 7: Our recommendations by income level
