CRNA Tax Playbook
The complete tax planning guide for Certified Registered Nurse Anesthetists — covering 1099 vs. W-2 income, S-Corp election, locum tenens deductions, retirement mega-contributions, and SSTB analysis for 2026.
The CRNA Tax Landscape
Certified Registered Nurse Anesthetists (CRNAs) are among the highest-paid advanced practice nurses, earning $200,000–$350,000 annually depending on practice setting, geography, and whether they work independently or under physician supervision. CRNAs who work as independent contractors — providing anesthesia services directly to hospitals, surgery centers, and dental offices under contract — have access to the full range of self-employed tax strategies.
A critical planning distinction: CRNAs are not performing services in a specified service trade or business (SSTB) under §199A. Unlike physicians, CRNAs are not on the SSTB list. The full 23% QBI deduction (OBBBA increased from 20%) is available to CRNAs below the 2026 phase-out threshold of $394,600 (MFJ). This is a significant advantage over physician clients who are subject to the SSTB limitation. At $250,000 in qualified business income, the QBI deduction is $50,000 — reducing taxable income by $50,000 and generating approximately $16,500 in federal tax savings at the 33% marginal rate.
The S-Corp election is the primary SE tax reduction tool for CRNAs with net income above $80,000. With a $100,000 reasonable salary and $250,000 in net income, the CRNA S-Corp saves approximately $10,000 in FICA taxes annually. Combined with the Solo 401(k) and QBI deduction, total annual tax savings can reach $40,000–$70,000 for a CRNA earning $250,000–$350,000.
CRNA QBI Deduction: Not an SSTB
The QBI deduction under §199A is one of the most valuable tax benefits available to CRNAs. Because anesthesia nursing is not an SSTB, the full 20% deduction is available below the phase-out threshold. The SSTB list includes: health (physicians, dentists, pharmacists), law, accounting, financial services, consulting, athletics, performing arts, and brokerage services. CRNAs are not on the list — they are providing a specialized nursing service, not practicing medicine as a physician.
| Income Level | QBI Deduction | Tax Savings (33%) |
|---|---|---|
| $150,000 net income | $30,000 | $9,900 |
| $200,000 net income | $40,000 | $13,200 |
| $250,000 net income | $50,000 | $16,500 |
| $300,000 net income | $60,000 | $19,800 |
QBI deduction phases out between $394,600–$494,600 (MFJ) in 2026. CRNAs above $394,600 in taxable income will see a reduced or eliminated QBI deduction.
S-Corp Election and Reasonable Salary
For CRNAs with net income above $80,000, the S-Corp election reduces SE tax by splitting income between W-2 salary (subject to FICA) and S-Corp distributions (not subject to FICA). The reasonable salary for a CRNA S-Corp is based on what an employed CRNA would earn for the same services. The American Association of Nurse Anesthesiology (AANA) salary survey shows employed CRNAs earning $180,000–$220,000 nationally. For S-Corp planning, practitioners typically set the salary at $90,000–$120,000 — the lower end of a defensible range for a part-time or independent contractor CRNA.
| Net Income | S-Corp Salary | FICA Savings/yr |
|---|---|---|
| $200,000 | $90,000 | ~$8,500 |
| $250,000 | $100,000 | ~$10,500 |
| $300,000 | $110,000 | ~$12,300 |
Retirement Plans and Tax Savings
The Solo 401(k) is the optimal retirement plan for a solo CRNA S-Corp. With a $100,000 W-2 salary, the S-Corp can contribute $24,500 (employee deferral) + $25,000 (employer at 25% of $100K) = $49,500 to the Solo 401(k) in 2026, generating approximately $16,335 in federal tax savings at the 33% marginal rate. For CRNAs age 50+, the catch-up contribution increases the employee deferral to $30,500, bringing total contributions to $55,500 and tax savings to approximately $18,315.
For CRNAs earning $300,000+ who want larger contributions, a cash balance defined benefit plan layered on top of the Solo 401(k) can add $80,000–$150,000 in additional deductible contributions depending on age. The combined Solo 401(k) + cash balance contribution for a 50-year-old CRNA earning $300,000 can reach $180,000–$220,000, generating $60,000–$73,000 in annual tax savings.
Frequently Asked Questions
No — CRNAs are not on the SSTB list under §199A. The full 23% QBI deduction (OBBBA increased from 20%) is available to CRNAs below the 2026 phase-out threshold of $394,600 (MFJ). This is a significant advantage over physician clients who are subject to the SSTB limitation. At $250,000 in qualified business income, the QBI deduction is $50,000 — generating approximately $16,500 in federal tax savings at the 33% marginal rate.
The AANA salary survey shows employed CRNAs earning $180,000–$220,000 nationally. For S-Corp planning, practitioners typically set the salary at $90,000–$120,000 — the lower end of a defensible range for a part-time or independent contractor CRNA. Document the salary determination with AANA survey data in the client file each year. The IRS scrutinizes CRNA S-Corp salaries; salaries below $80,000 for a full-time CRNA are difficult to defend.
Yes, if the CRNA maintains a tax home and the assignment is temporary (expected to last less than one year under §162(a)(2)). The deduction includes transportation, lodging, and 50% of meals. Document the expected duration of each assignment at the outset. If an assignment becomes indefinite, the travel deduction stops at that point. CRNAs who work exclusively as locum tenens with no fixed practice location may have difficulty establishing a tax home.
The S-Corp election and QBI deduction work together. The S-Corp distributions (not the W-2 salary) are the qualified business income eligible for the 23% QBI deduction (OBBBA increased from 20%). With $100,000 in W-2 salary and $150,000 in S-Corp distributions, the QBI deduction is 20% of $150,000 = $30,000. The W-2 salary is not QBI. This means the S-Corp election slightly reduces the QBI deduction base (by converting some income to W-2) but the FICA savings more than offset the reduction in QBI deduction.
Layer a Solo 401(k) ($55,500 with age 50+ catch-up on a $100K W-2) with a cash balance defined benefit plan ($80,000–$150,000 depending on age). Combined contributions can reach $180,000–$220,000, generating $60,000–$73,000 in annual tax savings at the 33% bracket. Add a backdoor Roth IRA ($7,500) for tax-free growth. The cash balance plan requires an enrolled actuary and a minimum three-year commitment.
