What Is Taxable as a 1099 CRNA: Income, Stipends, and Deductions Explained
Going from W-2 to 1099 changes your entire relationship with the IRS. As an employee, your employer handled withholding, reported your income, and split payroll taxes with you. As a 1099 contractor, you are responsible for tracking what is taxable, what is not, what you can deduct, and what you owe every quarter. Most new 1099 CRNAs get at least one of these wrong in year one. Here is a plain-language breakdown.
The Starting Point: What the IRS Sees
When you work as a 1099 contractor, every agency or facility that pays you $600 or more in a calendar year is required to issue you a Form 1099-NEC showing your total gross payments. That number goes on your tax return as self-employment income. It is your starting point, not your ending point.
From that gross number, you subtract legitimate business deductions to arrive at your net self-employment income. You then pay self-employment tax (15.3% on 92.35% of net income up to the Social Security wage base, then 2.9% Medicare tax above that) plus federal and state income tax on the net amount.
The difference between gross income and net income is where most of the tax planning happens. A CRNA who earns $280,000 gross but has $45,000 in legitimate deductions pays taxes on $235,000, not $280,000. At a 32% marginal rate, that difference saves roughly $14,400 in federal income tax alone, on top of the SE tax reduction.
What Is and Is Not Taxable
| Item | Tax Status | Notes |
|---|---|---|
| Clinical hourly or weekly contract pay | Taxable | Your primary 1099-NEC income. Fully subject to SE tax and income tax. |
| Call pay and overtime | Taxable | Paid as part of contract compensation. Treated the same as base rate. |
| Completion bonuses | Taxable | Reported on 1099-NEC. Taxable in the year received. |
| Housing stipends (tax home rules met) | Not taxable | Must maintain a tax home and be working away from it. See section below. |
| Travel and per diem stipends (tax home rules met) | Not taxable | Same tax home requirement applies. |
| Housing stipends (no tax home) | Taxable | If you have no permanent residence, all stipends are taxable income. |
| Malpractice premiums reimbursed by agency | Not taxable | If paid directly by agency, not income to you. If reimbursed, deductible expense. |
| Credentialing and licensing fee reimbursements | Conditional | If included in your 1099, deductible as a business expense. Net effect is zero. |
| CME reimbursements | Conditional | If added to your 1099, deductible. If paid directly by facility, not your income. |
| Solo 401k contributions | Not taxable (deferred) | Pre-tax contributions reduce your taxable income dollar for dollar. |
| Health insurance premiums (self-employed) | Deductible | 100% deductible as an above-the-line deduction, reducing adjusted gross income. |
The Housing Stipend Question
This is the one that trips up the most CRNAs going locums, and the stakes are high. A housing or travel stipend can be $1,500 to $3,000 per week. Over a 13-week assignment that is $20,000 to $39,000. Whether that is tax-free or fully taxable depends entirely on one thing: whether you qualify as a traveler under IRS rules.
The IRS considers stipends tax-free if you meet two conditions. First, you must have a legitimate tax home -- a permanent residence where you have ongoing expenses (rent, mortgage, utilities) and where you return when not on assignment. Second, you must be working away from that tax home on a temporary basis, generally defined as less than one year at the same location.
If you give up your apartment, put your belongings in storage, and travel full-time with no permanent home base, the IRS considers you an itinerant worker with no tax home. In that case, every housing and travel stipend you receive is ordinary taxable income. This catches a lot of new locums CRNAs who think the stipend is always tax-free.
Maintaining a tax home does not have to be expensive. Renting a room, maintaining a lease with a family member at fair market value, or owning a home you return to between assignments all count. The key is that you have real, ongoing housing costs at your primary location and can document them.
Even with a valid tax home, stipends become taxable if you work at the same facility for more than 12 months. The IRS views that as your new tax home, eliminating the tax-free treatment going forward. If you extend a contract past the 12-month mark, talk to a CPA about how this affects your stipend classification before signing.
Deductions: What You Can Subtract
This is where 1099 status works in your favor. As a W-2 employee, your ability to deduct work-related expenses is extremely limited. As a self-employed contractor, a wide range of legitimate business expenses reduce your taxable income directly.
Malpractice insurance premiums
Fully deductible as a business expense. If you pay $6,000 per year for individual coverage, that reduces your net self-employment income by $6,000 before any taxes are calculated.
Health insurance premiums
Self-employed CRNAs can deduct 100% of health, dental, and vision insurance premiums for themselves and their families as an above-the-line deduction. This reduces your adjusted gross income, not just your taxable income, which has additional downstream benefits.
Professional licensing and DEA registration
State license renewal fees, DEA registration, NBCRNA recertification fees, and similar professional credentialing costs are deductible business expenses. Track every one of them.
Continuing medical education
Conference registration, travel to CME events, required courses, and related materials are deductible. If your contract does not include a CME allowance, you are paying for this yourself and should be deducting every dollar.
Professional association dues and subscriptions
AANA membership, specialty society dues, clinical reference subscriptions, and similar professional memberships are deductible as ordinary business expenses.
Home office deduction
If you use a dedicated space in your home regularly and exclusively for business -- reviewing contracts, managing billing, business calls -- you can deduct either $5 per square foot (simplified method, up to 300 sq ft) or the actual proportional cost of that space. Requires the space to be used only for business, not also as a guest room or general workspace.
Business mileage and travel
Driving to and from assignment locations, airports, and business-related destinations is deductible at the IRS standard mileage rate (67 cents per mile in 2024). Keep a mileage log. Commuting from home to a regular workplace is not deductible, but travel to temporary work locations typically is.
Clinical equipment and supplies
Stethoscopes, monitoring equipment, clinical reference materials, scrubs used exclusively for work, and similar items you purchase yourself are deductible. Keep receipts.
Half of self-employment tax
This one is automatic and often overlooked. The IRS allows you to deduct half of your self-employment tax from your gross income as an above-the-line deduction. On $30,000 in SE tax, that is a $15,000 deduction. Your tax software or CPA handles this, but it is worth knowing it exists.
Retirement contributions
Solo 401k contributions reduce your taxable income dollar for dollar. In 2025, you can contribute up to $70,000 between the employee and employer sides. At a 32% marginal rate, maxing a Solo 401k saves roughly $22,400 in federal income tax in addition to the deferred growth.
CPA and professional fees
What you pay your accountant, tax preparer, and financial advisor for business-related services is a deductible business expense. The cost of getting this right is itself a write-off.
Quarterly Estimated Taxes
As a 1099 contractor, nobody withholds taxes for you. The IRS expects you to pay estimated taxes four times a year: April 15, June 15, September 15, and January 15. Missing these deadlines results in an underpayment penalty on top of whatever you owe in April.
A workable starting point for most 1099 CRNAs is to set aside 28 to 32 percent of every payment received into a separate savings account. This covers federal income tax and self-employment tax for most income levels. If you are in a high-tax state, push that closer to 35 to 38 percent.
You receive a $24,000 payment for a 4-week locums block. Transfer $7,200 (30%) to your tax savings account immediately. Leave it there. At quarter end, send the estimated payment to the IRS via EFTPS. Whatever is left in the tax account after April filing is yours to keep.
The goal is to never be surprised by a tax bill. The money is already accounted for before you spend anything.
If your income varies significantly quarter to quarter, work with a CPA to calculate your actual estimated payments rather than using a flat percentage. Underpaying in high-income quarters and overpaying in low-income quarters creates cash flow problems that are easy to avoid with accurate quarterly projections.

Open Tax EstimatorThe Deductions Most CRNAs Miss
After working through the common deductions, a few consistently get overlooked.
Cell phone and internet. If you use your phone and home internet for business purposes (and most 1099 CRNAs do, for scheduling, contracts, and communication), the business-use percentage is deductible. If you use your phone 70% for business, 70% of the annual cost is a deductible expense.
Bank and transaction fees. Monthly fees on your business checking account, wire transfer fees, and payment processing costs are deductible business expenses. They are small individually but add up over a year.
Uniforms and scrubs. Scrubs and clinical attire required for work that are not suitable for everyday wear are deductible. Keep receipts. The IRS is specific about this: the clothing must be required for work and not adaptable to general use.
Travel to interviews and credentialing visits. If you travel to visit a facility before accepting an assignment, or travel for credentialing purposes, that travel cost may be deductible as an ordinary business expense. Keep documentation of the purpose of the trip.
Software and subscriptions used for business. Tax software, accounting software, clinical reference apps, contract review tools, and similar subscriptions used for your business are deductible. Keep a list at the end of each year -- these are easy to forget.
What to Track and How
The deductions above are only useful if you can document them. An IRS audit requires receipts and records. "I think I spent about that much" is not documentation.
The simplest system that works: a dedicated business credit card used exclusively for business expenses, reviewed and categorized monthly. At year end, export the statement and hand it to your CPA. Every deductible expense is already in one place with a receipt attached to the transaction. This alone eliminates most of the friction around tax prep and audit protection.
A business checking account paired with a business credit card keeps your finances clean, makes deduction tracking automatic, and takes about 20 minutes per month to maintain. It is the single highest-leverage administrative habit for a 1099 CRNA.
The Bottom Line
Taxable income as a 1099 CRNA is not your gross 1099-NEC number. It is what is left after legitimate deductions, the SE tax deduction, retirement contributions, and health insurance premiums. For a CRNA grossing $280,000, those reductions can bring the taxable number down to $190,000 to $210,000, depending on the specific situation.
The difference between a CRNA who tracks everything and one who does not is not a minor rounding error. It is often $15,000 to $25,000 per year in taxes unnecessarily paid. The tax code is not in your favor by default. You have to know what you are entitled to and document it.
If you have not already found a CPA who works specifically with 1099 healthcare contractors, that is the highest-value use of the money you will save from reading this post.
