1099 vs W-2 Taxes —
What You Can (& Can't) Write Off
A complete, sourced breakdown of every major expense category — what's deductible, what's not, and why it matters for your LLC.
In medical device sales, your employment classification determines how you're taxed, what you can deduct, and how much of your commission check actually stays in your pocket. This is the foundation.
The One Big Beautiful Bill Act (signed 2025) permanently eliminated the miscellaneous itemized deduction for unreimbursed employee business expenses. If you're a W-2 rep driving 40,000 miles a year to hospitals, you get zero federal deduction for it. Same for your phone bill, scrubs, or any tool you pay out of pocket. This is one of the strongest financial arguments for pursuing 1099/LLC structure when you have the option.
Every 1099 deduction must meet this test from IRC Section 162: the expense must be (1) ordinary — common and accepted in your trade or business, and (2) necessary — helpful and appropriate to your work. It does not mean essential or indispensable — just reasonable and relevant. When in doubt, ask: "Would another med device rep in my position spend this money to do their job?" If yes, it likely qualifies.
Every major expense category a medical device rep might encounter — with the IRS rules, what's in, what's out, and the real-world notes your CPA wants you to know. Sources: IRS Pub. 463, Pub. 535, Insureon, TurboTax 2025, Jackson Hewitt, Keeper Tax.
| Expense | 1099 LLC | W-2 Employee | Notes & Limits |
|---|---|---|---|
Business Mileage (standard rate) Driving to hospitals, surgery centers, offices, client visits 70¢/mile in 2025 · 72.5¢/mile in 2026 |
✓ | ✗ | Log every trip contemporaneously. Commute from home to first appointment = NOT deductible unless home is your primary office. App like MileIQ or Everlance required. |
Gas / Fuel (actual expense method) Only if using actual expense method — not both |
✓ | ✗ | Must choose one method per vehicle per year from Year 1. Standard mileage already includes gas — can't double-deduct. Actual method: multiply total gas cost by business-use %. |
Car Insurance (actual expense method) |
✓ | ✗ | Deduct business-use percentage only. Standard mileage rate already covers this — do not deduct both. Source: IRS Topic 510. |
Car Depreciation (actual expense method) Section 179 or MACRS depreciation on business vehicle 2025 Year-1 limit: $20,200 w/ bonus depreciation |
✓ | ✗ | Luxury car caps apply. 2025: Year 1 = $20,200; Year 2 = $19,600; Year 3 = $11,800; Year 4+ = $7,060. SUVs over 6,000 lbs get better treatment (60% bonus depreciation in 2025). Must track business-use % rigorously. |
Car Repairs & Maintenance Oil changes, tires, brakes — actual method only |
✓ | ✗ | Deduct the business-use % of total repairs. Keep all repair receipts. Standard mileage already includes maintenance — can't combine methods. |
Registration Fees & License Plates |
✓ | ✗ | Business-use % only under actual expense method. The value-based portion of personal property tax is deductible separately even under the standard mileage rate. |
Parking Fees & Tolls |
✓ | ✗ | 100% deductible under EITHER method — these are NOT included in the standard mileage rate. Parking tickets and fines are NOT deductible. |
Car Loan Interest |
Partial | ✗ | Only the business-use % of auto loan interest is deductible for self-employed, under the actual expense method. Personal vehicle loan principal is never deductible. |
Personal Commute (home to first stop) Driving from your house to the first hospital of the day |
✗ | ✗ | IRS: commuting is personal. Exception: if your home office is your primary place of business (you must pass the "principal place of business" test), then travel from home to clients IS deductible. |
| Expense | 1099 LLC | W-2 Employee | Notes & Limits |
|---|---|---|---|
Business Meals with Clients / Surgeons Lunch with a surgeon, coffee with an OR nurse, dinner with a hospital buyer |
50% | ✗ | 50% of cost is deductible. You MUST document: date, location, who attended, and business purpose. Keep receipts. "Working lunch" while alone at your desk does NOT qualify. |
Meals During Business Travel Meals while traveling overnight for work — conferences, training, territory |
50% | ✗ | 50% deductible when traveling away from home for business overnight. The trip must have a primary business purpose. Meals at home or near your tax home are not covered here. |
Entertainment (tickets, golf, events) Sporting events, concerts, golf rounds with clients |
✗ | ✗ | TCJA 2017 eliminated the entertainment deduction entirely. Even if it's a 100% business purpose, client golf rounds, concert tickets, sporting events = NOT deductible. This has NOT been restored. |
Snacks / Coffee Working Alone Buying a coffee while working on a laptop at a café |
✗ | ✗ | The IRS does not allow deductions for meals you eat while working on tasks you could do from home. Personal sustenance is not a business expense. |
Team / Employee Meals (if applicable) If you hire subs or have team meetings with food |
50% | N/A | Office parties and company-wide events may be 100% deductible. Meals provided to employees primarily for the employer's convenience may still qualify at 50%. CPA guidance advised. |
Clothing is deductible ONLY if: (1) it is required for your work, AND (2) it is NOT suitable for everyday wear. The IRS does not care whether you'd actually wear it outside of work — they care whether you could. Source: TurboTax, Keeper Tax, Pantana CPA 2026.
| Expense | 1099 LLC | W-2 Employee | Notes & Limits |
|---|---|---|---|
Medical Scrubs Required for OR access in surgical environments |
✓ | ✗ | Scrubs are "contextually associated with medical work" and generally qualify as industry-specific uniforms. The IRS recognizes they are not typical street wear. Source: Beancount.io 2026, TurboTax. |
Branded Company Gear / Logo'd Items Polos, jackets, hats with your LLC or client company logo |
Partial | ✗ | A strategic workaround: clothing with your business name/logo prominently displayed may qualify as a marketing/advertising expense rather than clothing. The IRS still expects work-relatedness. Source: UniformMarket.com. |
Business Suits / Dress Clothes Suits, dress shirts, blazers, ties worn to sales calls |
✗ | ✗ | Even if you only wear your suit to client meetings, it fails the IRS test because it is suitable for everyday wear. This applies to real estate agents, lawyers, and sales reps equally. Tax Court has upheld this consistently. Source: Pantana CPA 2026, Keeper Tax. |
Dress Shoes / Business Casual Footwear |
✗ | ✗ | Loafers, dress shoes, and most footwear worn "for work" are not deductible because they're wearable outside of work. Safety boots (steel-toe, electrically rated) for industrial use are deductible. |
Khakis, Polos, Generic Professional Wear Standard business casual often required by med device companies |
✗ | ✗ | Fails the everyday wear test. Even if your employer explicitly requires khakis and a white polo, it's still deductible only if you'd never wear them outside work — which the IRS won't accept for generic clothing. |
Dry Cleaning / Laundry for Qualifying Items Cleaning costs for scrubs, OR-wear, or other deductible clothing |
✓ | ✗ | If the underlying clothing qualifies (e.g., scrubs), then dry cleaning or laundry expenses for those items also qualify. Keep receipts. Source: TurboTax, ReceiptOrg. |
Watch / Jewelry |
✗ | ✗ | The IRS never allows deductions for watches, regardless of business use. Source: Sterling CPA 2026. |

Home Office Deduction Dedicated space used exclusively and regularly for business Simplified: $5/sq ft, max 300 sq ft = up to $1,500/yr |
✓ | ✗ | The space must be used EXCLUSIVELY for business — a guest room with a desk doesn't qualify. Two methods: simplified ($5/sq ft, max 300 sq ft) or actual (% of home used for office × home expenses). Source: IRS Pub. 587. |
Rent / Mortgage Interest (home office %) |
✓ | ✗ | Actual method only. Calculate % of home's sq footage used for office. Renters can deduct that % of monthly rent. Homeowners deduct that % of mortgage interest, insurance, utilities, and repairs. |
Home Utilities (office %) Electric, gas, internet attributable to home office use |
✓ | ✗ | Under actual method, deduct the business-use % of utilities. Internet is handled separately — see Phone & Internet below. |
| Expense | 1099 LLC | W-2 Employee | Notes & Limits |
|---|---|---|---|
Cell Phone Bill (business use %) Monthly plan for calls, texts, emails, apps $150/mo × 80% business = $1,440/yr deduction |
Partial | ✗ | Deduct the percentage of your phone used for business. Be honest — if it's personal and business, estimate realistically (70–90% is defensible for most reps). A dedicated business line = 100% deductible. |
Home Internet (business use %) |
Partial | ✗ | Deduct the business-use percentage. Most reps can reasonably claim 50–70%. If you have a qualifying home office, the home office calculation may already cover this. |
Laptop / Computer Purchase price of computer used for business $2,000 laptop, 90% business use = $1,800 deductible |
✓ | ✗ | Section 179 allows full deduction in Year 1. Or depreciate over 5 years under MACRS. If used for personal purposes too, deduct business-use % only. Keep proof of business use. |
Software Subscriptions CRM, Microsoft 365, Zoom, Salesforce, LinkedIn Premium, etc. |
✓ | ✗ | 100% deductible if business-use only. LinkedIn Premium used for prospecting, CRM subscriptions, sales tools — all fully deductible. Netflix is not. |
iPad / Tablet |
✓ | ✗ | Deductible at business-use %. If you use it for showing product videos, OR navigation, and case reference — high business-use % is defensible. Section 179 eligible. |
| Expense | 1099 LLC | W-2 Employee | Notes & Limits |
|---|---|---|---|
Flights for Business Travel AAOS, NASS, spine society, product training trips |
✓ | ✗ | 100% deductible if primary purpose is business. If mixing personal + business, deduct only the business-allocated portion. Upgrade to first class is deductible only to the extent of equivalent economy cost per some interpretations — check with CPA. |
Hotel / Lodging |
✓ | ✗ | 100% deductible for business nights. Must be away from your "tax home" overnight. Extravagant hotel choices invite scrutiny — choose reasonable accommodations. |
Industry Conferences (registration fees) EPM events, NFLPA programs, medical conferences |
✓ | ✗ | 100% deductible. Keep your registration confirmation as documentation. Combined travel + conference costs are all deductible if the primary purpose is professional development. |
Purely Personal Vacation |
✗ | ✗ | Vacation with no business purpose is never deductible. The "one business meeting" trick does not make a personal trip deductible — primary purpose must be business. |
| Expense | 1099 LLC | W-2 Employee | Notes & Limits |
|---|---|---|---|
EPM Program Tuition / Costs Costs of your EPM training to enter medical sales |
✓ | ✗ | Once you are engaged in the trade of medical device sales, education expenses that maintain or improve your current skills are deductible. Education for a NEW career (from scratch) is not. Source: IRS Pub. 970. |
CNPR Certification / Industry Certs |
✓ | ✗ | Professional certifications directly related to your business are deductible. Licensing fees and renewal fees are also deductible under business licenses (Sch. C, Line 23). |
Books, Courses, Industry Subscriptions Sales methodology books, anatomy courses, OR survival training |
✓ | ✗ | Business books, trade publications, online courses, and industry subscriptions (medical journals, Medscape Pro) are deductible as ordinary business expenses. |

General Liability Insurance Business liability policy for your LLC |
✓ | ✗ | 100% deductible as a business expense. Protects your LLC from client or third-party claims. Typical cost $500–$1,500/year. |
SEP-IRA Contributions Self-employed retirement savings account Up to 25% of net SE income, max $70,000 (2025) |
✓ | ✗ | Contributions reduce your taxable income dollar-for-dollar. The single biggest tax lever available to 1099 reps at high income. Must be funded by tax return due date (including extensions). Source: Insureon 2026. |
Solo 401(k) Contributions |
✓ | N/A | Employee deferral up to $23,500 (2025) + employer contribution of up to 25% of compensation. Total cap $70,000. More flexible than SEP-IRA for reps with variable income. |
HSA Contributions (with HDHP) |
✓ | ✓ | If you have a qualifying high-deductible health plan, HSA contributions are deductible above-the-line. Grows tax-free, spends tax-free on medical expenses. Triple tax advantage. |
| Expense | 1099 LLC | W-2 Employee | Notes & Limits |
|---|---|---|---|
CPA / Accountant Fees |
✓ | ✗ | The portion of your CPA's fee attributable to your Schedule C business is deductible. Budget $800–$2,500/year. It pays for itself many times over. |
LLC Formation / Legal Fees State filing fees, attorney fees to set up your LLC |
✓ | ✗ | Up to $5,000 in startup costs deductible in Year 1 (including LLC filing fees, legal fees, market research). Amounts over $5,000 must be amortized over 180 months. Source: Rippling 2026. |
Office Supplies Pens, paper, folders, shipping materials, printer ink |
✓ | ✗ | 100% deductible. Must be supplies used up during the year — you can't stock up on $2,000 of paper clips December 31 and deduct it all. Source: Deel 2026. |
Marketing & Advertising Business cards, LinkedIn ads, website hosting, branded materials |
✓ | ✗ | 100% deductible. Includes business cards, website hosting/design, LinkedIn Premium, Google Ads, and promotional swag. Political advertising is NOT deductible. |
Business Bank Fees |
✓ | ✗ | Monthly fees for your dedicated business checking account are deductible. Another reason to have a separate business account — makes documentation cleaner and fees deductible. |
Client Gifts Holiday gifts, thank-you gifts to referring surgeons |
$25 cap | ✗ | The IRS caps business gift deductions at $25 per person per year. Also, be aware of Sunshine Act / anti-kickback rules in healthcare — check compliance before gifting to HCPs. |
Self-Employment Tax (50% deduction) |
✓ | N/A | You can deduct 50% of SE tax paid as an above-the-line adjustment to income on Schedule 1. This partially levels the playing field with W-2 employees. Source: IRS, Insureon 2026. |
Political Donations / Lobbying |
✗ | ✗ | Contributions to political parties, PACs, candidates, or lobbying organizations are NEVER deductible as business expenses. |
Parking Tickets / Fines |

For most medical device reps, the vehicle deduction is the largest single write-off available. Understanding which method to use can be worth thousands of dollars. Source: IRS Topic 510, IRS Pub. 463, TurboTax 2025, Nolo, Block Advisors.
🛣️ Method 1: Standard Mileage Rate
🔧 Method 2: Actual Expense Method
You drive 16,200 business miles out of 18,000 total (90% business use). Your actual expenses: gas $3,000 + insurance $1,500 + repairs $500 + registration $500 = $5,000 × 90% = $4,500 deduction (actual method). Standard mileage: 16,200 × $0.70 = $11,340 deduction (standard mileage). Standard mileage wins by $6,840. This is common for high-mileage reps with economical vehicles. Source: TurboTax 2025 example.
1. Must choose standard mileage in Year 1 if you ever want the option to switch later. If you use actual expenses in Year 1 and claim accelerated depreciation, you're locked into actual expenses for that vehicle permanently.
2. Commuting is NEVER deductible — driving from home to your first appointment is commuting unless your home is your primary place of business (qualifying home office). Document this carefully.
3. Log trips contemporaneously — reconstruct mileage logs 6 months later and the IRS will reject them. Use MileIQ, Everlance, or similar apps that timestamp every trip.
4. Business use percentage — if you use the actual expense method and claim 80% business use, keep records to prove it. The IRS scrutinizes vehicle deductions heavily.
Source: IRS Pub. 463, Revenue Procedure 2025-16. Limits apply at 100% business use — scale down by your actual business-use %.
Same gross income. Two structures. Here's what actually changes in your take-home when you understand the 1099 LLC tax playbook.
W-2 Employee @ $150K
1099 LLC @ $150K (optimized)
At identical gross income, the 1099 LLC rep in this example takes home roughly $21,000 more per year than the W-2 employee — even after paying their own FICA and health insurance. The difference comes from $48,000 in documented write-offs and the QBI deduction. At $200K or $250K gross, this gap grows to $30,000–$50,000+ annually. Over a 10-year career, at modest investment returns, the compounding on that difference can exceed $400,000 in additional wealth.

For most EPM athletes entering medical device sales as a 1099 rep, a Single-Member LLC is the right starting structure. Here's how to do it correctly.
File Articles of Organization with Your State
File online with your state's Secretary of State office. Cost: $50–$200. Takes 1–3 business days in most states. South Carolina: $110 fee, done online via SOS.SC.GOV.
Obtain Your EIN (Employer Identification Number)
Apply at IRS.gov — free, 5 minutes online. Your EIN is your LLC's SSN. Use it for your bank account, contracts, and 1099s. Never give a client your personal SSN once your LLC is active.
Open a Dedicated Business Bank Account
Non-negotiable. Every commission goes in here. Every business expense paid from here. Mixing personal and business funds ("piercing the corporate veil") can eliminate your liability protection AND make your deductions less defensible.
Set Up Quarterly Estimated Tax Payments
Register at IRS Direct Pay (irs.gov/payments). Set aside 27–32% of every commission immediately into a separate "tax" savings account. Pay quarterly: April 15, June 15, Sept 15, Jan 15.
Start Tracking Everything Immediately
Download a mileage app (MileIQ, Everlance) and start logging trips on Day 1. Create an expense folder in Google Drive. Save every receipt. The IRS requires contemporaneous records — you cannot reconstruct logs after the fact and expect them to hold up.
Hire a CPA Who Specializes in Self-Employed Individuals
Budget $1,000–$2,500/year. A good CPA will identify deductions you'd miss, set up your books correctly, file your quarterly estimates, and keep you audit-ready. Their fee is fully tax-deductible. This is the most important investment you'll make in Year 1.
Once your net LLC profit consistently exceeds $80,000–$100,000, your CPA may recommend electing S-Corp tax status. Under an S-Corp, you pay yourself a "reasonable salary" (W-2) and take remaining profit as distributions — which are NOT subject to 15.3% SE tax. At $200K net, this can save $15,000–$25,000/year in SE taxes. It adds complexity (payroll, separate filings), so don't do it until the math clearly works. Your CPA will know the right timing.
You trained to perform under pressure with discipline and process. Apply the same system to your finances. Here's what separates reps who build wealth from those who earn big and break even.
🏈 Before Your First Commission Check
- File your LLC and get your EIN
- Open a dedicated business checking account
- Download MileIQ or Everlance — start logging immediately
- Hire a CPA with 1099 / self-employed experience
- Set up IRS Direct Pay for quarterly estimates
- Open a separate "tax savings" account — auto-transfer 30% of every deposit
- Decide: standard mileage or actual expense method (discuss with CPA Year 1)
📋 Year-Round Habits
- Log every business mile in real-time — never reconstruct
- Save every receipt (photo to Expensify, Dext, or Google Drive)
- Log every business meal: who, where, business purpose, amount
- Pay estimated taxes on time: April 15, June 15, Sept 15, Jan 15
- Review P&L with CPA quarterly, not just in April
- Max SEP-IRA before December 31 (or tax deadline w/ extension)
- Keep personal and business accounts 100% separate
🏆 High-Impact Write-Off Moves
- Mileage: 45K miles × 70¢ = $31,500 deduction — biggest single item
- SEP-IRA: Up to $70K/yr, dollar-for-dollar taxable income reduction
- Health insurance: Full family premiums deductible above-the-line
- QBI deduction: 20% of net business income — now permanent
- Section 179: Write off new equipment full cost in Year 1
- Branded scrubs / OR gear: Deductible; generic suits are not
- CPA fee: $1,500 CPA fee is tax-deductible and saves 5-10x its cost
⚠️ Mistakes That Cost Reps Thousands
- Mixing personal and business bank accounts
- Skipping quarterly payments → massive April bill + penalties
- Not tracking mileage until December → logs won't hold up in audit
- Trying to deduct suits, dress shoes, and generic business clothes
- Deducting personal meals as "business meals" without documentation
- Claiming 100% business vehicle use without records to prove it
- Waiting until Year 2 to form your LLC — start before first check
- Treating entertainment (golf, events) as deductible after 2017 law change
