What Do Therapists Need to Know About Taxes in Idaho?
Idaho may be low-frills when it comes to taxes — but that doesn’t mean it’s simple. If you’re running a therapy practice here, you’ll need to keep up with state income tax, business registrations, and the occasional quirks around sales tax or local requirements.
Who this guide is for
This guide is for:
- Licensed Idaho therapists (LCSWs, LPCs, LMFTs, psychologists, etc.)
- Solo and group practice owners
- Providers working in-person, online, or both
- Therapists looking to minimize tax liability and stay compliant
Step 1: Pick the right structure for your practice
Your business entity controls how you’re taxed and what paperwork you’ll file.
Sole Proprietorship
- Easiest to start — no entity formation required
- Profits taxed as personal income
- Offers no personal liability protection
- Must register a DBA if operating under a trade name
PLLC (Professional LLC)
- Idaho allows licensed professionals to form PLLCs
- Offers liability protection
- Default tax treatment: pass-through to personal return
- Can elect S Corp status for potential tax savings
- Requires registration with the Idaho Secretary of State and coordination with licensing board
S Corporation
- Helps reduce self-employment tax by splitting salary and distributions
- Requires payroll setup, bookkeeping, and separate tax filings
- Makes sense once you’re netting around $75K/year
- Still subject to Idaho personal income tax
Professional Corporation (PC)
- Permitted in Idaho
- More admin overhead
- May be taxed as S Corp with election
- More common for larger practices
Step 2: Know your state tax obligations
State income tax
- Idaho has graduated personal income tax rates, capped at 5.8% for 2025
- All income from pass-through entities flows to your individual return
- File using Form 40 (residents) or Form 43 (non-residents)
Annual report
- Required for PLLCs and PCs
- Due annually to the Idaho Secretary of State
- $20 filing fee — file online
Sales tax
- Therapy services are generally exempt from sales tax
- However, if you offer non-healthcare services (e.g., coaching, classes, products), consult with a tax advisor
- Sales tax rate: 6% statewide, with some local add-ons
Step 3: Pay taxes throughout the year — not just in April
Estimated taxes
- Required if you expect to owe $1,000+ to IRS or $200+ to Idaho
- Due quarterly: April 15, June 15, Sept 15, Jan 15
- File Idaho estimates using Form 51 or via tax.idaho.gov
Self-employment tax
- 15.3% for Social Security and Medicare
- Applies to net income from sole props and default PLLCs
- S Corp helps reduce this by splitting income
Filing requirements
- Sole prop: Schedule C + Idaho Form 40
- PLLC: Annual report + personal income return
- S Corp: 1120-S + Idaho Form 41S + W-2s + annual report
Step 4: Track and claim your deductions
Idaho therapists have access to the same deductions as other self-employed professionals — you just need to keep records.
Deductible expenses for therapists
- Office rent or eligible home office
- HIPAA-compliant telehealth and billing software
- Malpractice and liability insurance
- License renewals, CEUs, supervision
- Marketing, website, and directories
- Phone, internet, admin tools
- Retirement contributions
- Health insurance premiums
Step 5: When it’s time to consider an S Corp
If your net income is above $75K, you’re likely overpaying in self-employment tax.
- S Corp lets you pay a salary and take the rest as distributions
- Reduces self-employment tax on part of your income
- Requires payroll, separate tax return, and formal bookkeeping
- Still pays Idaho state income tax on total income
Step 6: Common mistakes therapists make
- Forgetting the $20 annual report for PLLCs and PCs
- Not registering a trade name (DBA) when using a business name
- Missing quarterly estimated payments
- Staying a sole prop too long
- Electing S Corp but skipping payroll setup
- Ignoring non-therapy income that may be subject to sales tax
Step 7: Our recommendations by income level
Net Income Range Suggested Action
Under $50K Sole prop or PLLC; file annual report; track every deduction
$50K–$100K Consider S Corp; run payroll; review quarterly with CPA
Over $100K Full S Corp setup; retirement plan strategy; tax planning essential
