Estimated taxes for CRNAs and locum tenens require more than a quarterly reminder because 1099 income, contract timing, state work, travel expenses, and reimbursements can all affect what should be reviewed before each deadline.
For 1099 CRNAs, locum tenens, nurse practitioners, and other healthcare contractors, estimated tax planning should connect with how income is actually earned. Working across multiple facility assignments requires tracking of income by contract, state, agency, and payment type to accurately estimate their tax liabilities.
Why Estimated Taxes Matter for 1099 CRNAs and Locum Tenens
Many CRNAs and locum tenens receive 1099 income. Unlike W-2 wages, 1099 income usually does not include employer withholding federal taxes, state taxes, Social Security, or Medicare.
Because of this, they may need to plan federal income tax, self-employment tax, and state tax obligations during the year. The IRS explains that estimated tax is used to pay tax on income that is not subject to withholding, including self-employment income. Self-employed individuals generally file an annual return and pay estimated taxes quarterly.
Estimated Tax Deadlines for CRNAs and Locum Tenens to Know for 2026
Taxpayers utilize the IRS Form 1040-ES package to figure out and pay estimated tax for the 2026 tax year. For 2026, the estimated tax payment deadlines fall on standard business days and follow this schedule:
| Income period | Deadline to pay estimated taxes |
| January 1 – March 31, 2026 | April 15, 2026 |
| April 1 – May 31, 2026 | June 15, 2026 |
| June 1 – August 31, 2026 | September 15, 2026 |
| September 1 – December 31, 2026 | January 15, 2027 |
Track 1099 Income by Contract or Assignment
Tracking 1099 income by contract, agency, facility, and assignment helps you see whether income has increased or decreased since your last estimated tax payment.
You should also separate W-2 income from 1099 income. W-2 withholding may cover part of your total tax liability, but 1099 income may still require separate planning, especially when contract timing changes. A high-income quarter may need a different estimated tax review than a slower quarter.
CRNAs or locum tenens providers switching from being employees to contractors need to do this review early on. Waiting until the end of the year could lead to underpayment, penalties, or cash flow issues.
Review Self-Employment Tax Before Each Deadline
Self-employment tax is distinct from regular income tax, covering the Social Security and Medicare taxes normally split between employers and employees.
Quarterly estimated tax payments are designed to cover both ordinary income tax and self-employment tax obligations. Because healthcare contractors do not have an employer withholding these funds, calculating this 15.3% tax rate component before each deadline keeps your quarterly vouchers accurate.
Track Multi-State Income and Work Locations
Locum tenens and CRNAs may work in multiple states throughout the year. So, it’s important to track where the actual service was provided rather than just focusing on where payments came from.
For every state, keep logs of your assignment dates, facility or agency name, gross income earned, reimbursements, any taxes withheld and related travel or lodging expenses. These notes can help with state income allocation, estimated tax planning, and year-end preparation.
Track Travel Expenses, Reimbursements, and Tax Home Details
Travel, lodging, and reimbursements can affect estimated tax planning, especially when assignments require temporary work away from home. To ensure your income and write-offs are not overstated, track agency reimbursements separate from your out-of-pocket expenses.
The IRS states that business travel expenses may be deductible when paid or incurred for a temporary work assignment away from home, whereas indefinite assignments (lasting or expected to last longer than one year) face different tax treatments.
Before each estimated tax deadline, organize your travel receipts, lodging records, mileage logs, meal records, reimbursement summaries, and agency payment statements. Keeping clean financial records ensures each quarterly adjustment is mathematically sound.
Maximize 1099 CRNA Tax Deductions Prior to Payment
Your estimated tax payments should always reflect your net income after write-offs, not just your gross revenue. Evaluating eligible business expenses prior to the deadline prevents you from overpaying the IRS each quarter.
Common healthcare contractor tax deductions include:
- State licensing fees and credentialing costs
- Malpractice insurance premiums
- Continuing Education and professional dues
- Bookkeeping, legal, and specialized tax preparation fees
- Scheduling software, phone, and internet utilities
- Eligible travel, lodging, and vehicle expenses
