Tax Deductions Speech-Language Pathologists Actually Miss
Most SLPs leave money on the table every tax season. Continuing education, licensure fees, therapy materials, software subscriptions, mileage between schools and clients - all deductible, and most of it poorly tracked. Here's a practical checklist of what private practice and 1099 contract SLPs can write off, and how to document it so it survives an audit.
First: Understand What Changes When You Earn 1099 Income
W-2 vs 1099 Is a Different Tax World
As a W-2 employee, your employer pays half of your Social Security and Medicare taxes, and since 2018 you can't deduct unreimbursed job expenses on your federal return. As a 1099 contractor or practice owner, you pay both halves yourself - 15.3% self-employment tax on net earnings - but every legitimate business expense reduces that net. A $500 CEU conference doesn't just save you $500 × your income tax rate; it also cuts self-employment tax. That's why tracking expenses matters far more for private practice SLPs than for employed ones.
Self-employment tax is 15.3% on net earnings, on top of federal and state income tax
Deductions reduce net earnings, so they cut both income tax and SE tax
You'll likely need to pay quarterly estimated taxes (April, June, September, January)
Mixed W-2 + 1099 income is common for SLPs - only the 1099 side gets Schedule C deductions
Half of your SE tax is itself deductible as an adjustment to income
The SLP Deduction Checklist
Professional Fees & Education
ASHA dues, state association dues, state licensure and renewal fees, teacher certification fees if required for your contracts, CEU courses, conferences (registration, travel, lodging, 50% of meals), specialty certifications like BCS-CL or LSVT training, and professional journals. If it maintains or improves skills in your current field, it's deductible. Education that qualifies you for a new profession is not.
Therapy Materials & Supplies
Assessment kits and protocols (CELF, GFTA response forms), articulation cards, games and toys used in sessions, books, sensory tools, laminators and printing supplies, rewards and stickers. Buy a $1,200 assessment kit? Under Section 179 or the de minimis rule you can usually deduct it fully in the year of purchase rather than depreciating it.
Software & Subscriptions
Practice management and billing software, teletherapy platforms, EMR systems, scheduling tools, digital therapy material subscriptions, worksheet generators like <a href='https://ga-loo.com' target='_blank' rel='noopener'>Ga-loo</a>, cloud storage, and the business-use share of your website hosting and email. Recurring subscriptions are easy to forget at tax time - export a year of statements and search for monthly charges.
Practice Operations
Professional liability insurance, general business insurance, office rent or the home office deduction, business phone line or the business-use percentage of your cell plan, internet (business-use share), advertising, business cards, directory listings like Psychology Today, credit card processing fees, and fees paid to your accountant or bookkeeper - yes, the cost of doing your taxes for the business is itself deductible.
The Home Office and Mileage: Biggest Wins, Most Mistakes
Home Office: Exclusive and Regular Use
If you run teletherapy sessions or do documentation from a dedicated room, you may claim the home office deduction - but the space must be used exclusively and regularly for the business. A guest room that doubles as your therapy studio doesn't qualify; a corner used only for work does. Two methods: simplified ($5 per square foot, up to 300 sq ft, max $1,500) or actual expenses (business percentage of rent or mortgage interest, utilities, insurance, repairs). Teletherapy SLPs with a dedicated room often do better with actual expenses.
Exclusive use is the rule the IRS actually enforces - don't claim a shared space
Simplified method: $5/sq ft up to 300 sq ft, no depreciation recapture to worry about
Actual method: measure the room, divide by home square footage, apply to eligible costs
A qualifying home office also makes trips from home to client sites deductible mileage
Mileage: The Deduction SLPs Under-Track Most
Itinerant SLPs driving between schools, clinics, and home-visit clients rack up serious miles. The standard mileage rate (around 70 cents per mile in recent years - check the current IRS rate) applies to business trips: between work sites, to trainings, to the bank for business errands. Commuting from home to a regular workplace is not deductible - unless your qualifying home office is your principal place of business, which flips most of your driving into business miles. Use a mileage app; a reconstructed log at tax time is the classic audit loser.
Commonly Missed SLP Deductions and Where They Go
| Expense | Deductible? | Where It Goes | Notes |
|---|---|---|---|
| ASHA dues + state license | Yes | Schedule C - Taxes & Licenses / Dues | Only for 1099/practice income, not W-2 side |
| CEU courses & conferences | Yes | Schedule C - Education | Travel and lodging too; meals at 50% |
| Therapy materials & games | Yes | Schedule C - Supplies | Keep receipts; personal-use toys don't count |
| Software subscriptions | Yes | Schedule C - Office expense | Billing, teletherapy, worksheet generators, EMR |
| Liability insurance | Yes | Schedule C - Insurance | Professional and general liability |
| Health insurance premiums | Often | Form 1040 adjustment | Self-employed health insurance deduction if not covered by a spouse's plan |
| Retirement (SEP-IRA / Solo 401k) | Yes | Form 1040 adjustment | Up to 25% of net SE earnings - the biggest tax lever for solo SLPs |
| Scrubs / regular clothing | Mostly no | - | Clothing suitable for everyday wear isn't deductible |
Schedule C categories are flexible - what matters is that the expense is ordinary, necessary, and documented. When in doubt, ask a tax professional who works with therapists.
What Good Tracking Is Worth
Typical annual deductions for a part-time private practice SLP
Quarterly Taxes and Recordkeeping Without the Pain
A System That Takes 20 Minutes a Month
You don't need enterprise accounting. Separate business bank account and card. Set aside 25-30% of every 1099 payment into a tax savings account the day it arrives. Once a month, categorize transactions in a simple bookkeeping tool or spreadsheet and snap photos of paper receipts. Pay quarterly estimates from the tax account. In January, everything is already categorized - your Schedule C practically fills itself in.
Set aside 25-30% of gross 1099 income for taxes as it comes in
Quarterly estimated payments avoid underpayment penalties
Digital receipts are fine with the IRS - photograph and forget
Log mileage in real time with an app, not retroactively
Keep records for at least 3 years, 7 to be safe

Common Scenarios SLPs Ask About
Real Situations, Practical Answers
Scenario 1: School SLP with a W-2 who sees four private clients on weekends. Only the private-client income goes on Schedule C, but ASHA dues, materials used for private clients, and the business share of subscriptions are deductible against it. Scenario 2: Full-time teletherapy contractor for a platform that sends a 1099. Everything in this guide applies - and the home office plus self-employed health insurance deduction are usually the two biggest items. Scenario 3: Growing group practice. Once net profit clears roughly $50-80k, ask a CPA about an S-corp election - the payroll-tax savings can be significant, but so is the added admin.
SLP Tax Questions, Answered
Can I deduct ASHA dues and my state license if I'm a W-2 school employee?
Not on your federal return - unreimbursed employee expenses were suspended for W-2 workers starting in 2018. But if you have any 1099 private practice income, dues and licensure that support that practice are deductible on Schedule C. Some states still allow employee expense deductions on state returns, so check yours.
Are toys and games really deductible?
Yes, if they're used for therapy. A deck of articulation cards, a game you use as a reinforcer, sensory tools - all supplies. The line is personal use: the board game that lives in your therapy bag is deductible; the one your own kids play every night is not. Keep therapy materials physically separate and the documentation takes care of itself.
How do software subscriptions work as deductions?
Fully deductible in the year paid if used for the business - billing platforms, teletherapy software, EMR, scheduling, and material-creation tools like Ga-loo. If a subscription is mixed personal and business use (say, cloud storage), deduct the business-use percentage and note how you estimated it.
Do I really need to pay quarterly estimated taxes?
If you expect to owe $1,000 or more for the year beyond withholding, yes - otherwise you may face underpayment penalties. SLPs with mixed W-2/1099 income have a shortcut: increase withholding at your W-2 job to cover the tax on your side income, and you can skip quarterly payments entirely.
Can I deduct my car?
You deduct business use of your car, not the car itself, via the standard mileage rate or actual expenses. Trips between work sites, to clients' homes, to trainings and conferences count. Ordinary commuting doesn't - unless your qualifying home office is your principal place of business. Whichever method you use, a contemporaneous mileage log is non-negotiable.
When should I talk to an accountant instead of using tax software?
Tax software handles a simple Schedule C fine. Bring in a professional when you have employees or contractors, when net profit approaches the range where an S-corp election makes sense, when you're claiming a large home office with actual expenses, or after any year with a big change - going full-time private, buying significant equipment, or opening a second location.
