Locum tenens tax planning should begin before your next assignment, as your contract structure, work location, travel arrangements, and income type can affect how your taxes are handled.
Locum tenens physicians, CRNAs, nurse practitioners, and other 1099 healthcare contractors achieve the best tax results when they plan before earning any income. Although a temporary assignment may look simple, specific details shift your tax obligations depending on your W-2 or 1099 payment status, your physical work location, who pays travel costs, and how you document your expenses.
Why Locum Tenens Tax Planning Should Start Before the Assignment

Unfortunately, many healthcare providers wait until tax season to organize their income and expenses. Planning before your assignment helps clarify tax obligations early, ensuring that you do not miss critical administrative windows.
Locum tenens work often involves temporary contracts, variable income, and changing work locations. According to the National Association of Locum Tenens Organizations (NALTO), locum tenens doctors typically contract with recruitment agencies to provide medical services for a healthcare organization over a defined period, often as independent contractors. You can review the NALTO guide on locum tenens work arrangements.
Review Your Contract Structure First
First, you need to know whether you will be paid as a W-2 or 1099 before accepting a locum tenens assignment. W-2 income usually includes tax withholding, while 1099 locum tenens income usually does not.
If the assignment is 1099, plan for income tax, self-employment tax, and estimated payments. The IRS explains that self-employed individuals generally file an annual return and pay estimated taxes quarterly. Review the IRS self-employed tax obligations for more detail.
Also, confirm who is responsible for paying your travel expenses, housing costs, licensing fees, malpractice insurance, credentialing fees, and reimbursements. If the assignment crosses state lines, track where you work because state taxes may apply.
Plan for Estimated Taxes Before Income Starts Coming In

Estimated taxes help pay taxes during the year. For locum tenens providers, this can be especially important because income may change from one assignment to the next.
Before the contract starts, calculate your projected earnings, deductions, state tax exposure, and business expenses. The IRS says estimated tax calculations should consider expected adjusted gross income, taxable income, taxes, deductions, and credits for the year. You can review the IRS estimated tax guidance.
A separate tax reserve can also help. Instead of letting all income flow into personal spending, set aside a percentage of each payment for taxes, emergency savings, retirement, and business expenses.
Track Travel Expenses and Tax Home Details

Your travel expenses can be a significant deduction, but they depend on your tax home, assignment length, reimbursement terms, and documentation.
The IRS says travel expenses may be deductible for a temporary work assignment away from home, but not for indefinite assignments. Any assignment expected to last more than one year is generally considered indefinite. You can review the IRS business travel expense guidance.
To support tax preparation and year-end planning, keep your contract, work location, assignment dates, travel receipts, lodging records, mileage logs, reimbursements, and state income notes organized from the start.
Know Which Locum Tenens Tax Deductions May Apply
Locum tenens tax deductions may include licensing fees, professional dues, malpractice insurance, continuing education, travel and lodging, mileage, business meals, phone and internet business use, software subscriptions, tax preparation, and bookkeeping fees.
These expenses may qualify depending on business purposes, reimbursement arrangements, documentation, and tax home rules. For example, an unreimbursed travel expense may be treated differently from an expense fully paid by the agency.
Strong records matter. A mileage log, contract, and receipt provide better support than a rough estimate prepared during tax season.
Set Up Bookkeeping Before the Assignment Begins

Bookkeeping should be in place before the assignment starts.
A separate bank account helps keep income and expenses organized. It also reduces the chance that personal spending, contract income, reimbursements, and tax savings become mixed together.
Clean books make it easier to track assignment-level income and expenses. They also support estimated tax projections and year-end filing. If income becomes consistent, bookkeeping may also support an S-Corp review.
