IRS Code Substantiation

Machine Precision
Self-Employment Tax Governing Formula:
SE Tax = (Net Profit · 0.9235) · [ 12.4% (up to $168,600) + 2.9% Medicare ]
Arbitrage = Locum Inflows - Deductions - Duplicated Housing - All Taxes - W2 Net

Step-by-Step Statutory Derivation

1
Non-Taxable GSA Per Diem Sizing

Reimbursed travel expenses under accountable GSA plans (lodging, meals, and incidentals) are 100% tax-free under IRC Section 62(a)(2)(A), provided duplicated housing is maintained.

2
The SE Tax Drag vs. Deductibility

1099 contractors pay both employer and employee portions of FICA (15.3%). However, 50% of the SE tax is directly deductible as an adjustment to income on Form 1040 Schedule 1.

3
Solo 401(k) / SEP-IRA Tax Deferral

In addition to employee deferrals up to $23,000, 1099 clinicians can contribute 20% of net self-employment earnings as an employer profit share, sheltering up to $69,000 from current federal and state taxes.

Frequently Asked Questions: Locum Tenens Taxes

What is required to receive non-taxable travel stipends under IRS rules? +
Under IRS Revenue Ruling 73-529, a traveling clinician must maintain a legitimate 'tax home' (permanent residence where they incur substantial ongoing living expenses) and incur duplicated lodging/meal expenses while traveling away from home for temporary clinical assignments.
When should a locum tenens physician or CRNA elect S-Corporation status? +
S-Corporation election typically becomes mathematically advantageous once net 1099 earnings exceed $150,000 to $200,000. By paying oneself an IRS 'reasonable compensation' salary and taking the remaining net profit as a corporate distribution, the provider saves 15.3% in self-employment tax on the distribution portion.
