CRNAs and nurse practitioners often earn high income across multiple states; however, many assume they only owe state tax where they live. That assumption creates a serious risk.
Consider this scenario:
- You live in Texas.
- You accept a 13-week contract in California.
- Later, you take another 13-week contract in New York.
Texas has no state income tax. However, California and New York aggressively enforce nonresident filing requirements. As a result, you may owe tax in both states, even if you never move.
States audit high-income healthcare contractors. California, in particular, increases enforcement through its Franchise Tax Board (FTB). If you earn substantial income in the state, you are on their radar.
Let’s break down when you actually owe state income tax.
Why Multi-State Tax Is a Serious Issue for CRNAs, Nurse Practitioners, and Locum Tenens Professionals
Multi-state tax matters because states tax income where it is earned, not just where you live.
For example, you may live in Texas and earn $70,000 during a 13-week contract in California. California considers that income California-sourced. Therefore, California expects you to file a nonresident return and pay tax on that portion.
However, many healthcare professionals ignore this obligation. As a result, states assess penalties and interest years later. You cannot rely on where your LLC is registered. States tax income based on physical work location.
When Do You Have to File a Nonresident State Return?
You must file a nonresident return when you earn income physically in a state.
States have the authority to tax income sourced within their borders. Therefore, if you perform services in that state, the income becomes taxable there.
Income Allocation for 13-Week Contracts
CRNAs often work 13-week contracts. You must allocate income based on days worked in each state.
For example:
A CRNA earns $180,000 during the year:
- 13 weeks in California
- 13 weeks in New York
- 26 weeks in Texas
Assume equal pay across assignments. Each 13-week period represents roughly 25% of annual income.
- California: $45,000
- New York: $45,000
- Texas: $90,000
California and New York tax their respective $45,000 portions. Texas does not impose state income tax.
What If Your Home State Has No Income Tax?
Living in a no-tax state does not shield you from other states’ tax laws.
For example, a Texas resident working in California still owes California tax on California-sourced income.
California law requires nonresidents to file when income exceeds filing thresholds. You can review California’s nonresident filing guidance here.
Therefore, your home state’s tax structure does not eliminate other states’ rights to tax income earned there.
Credit for Taxes Paid to Another State – Avoiding Double Taxation
Even if you owe tax in two states, you usually do not pay tax twice on the same income.
How the Credit Mechanism Works
Your resident state typically provides a credit for taxes paid to another state.
For example:
You live in Georgia. You work a 13-week contract in New York. New York taxes that income. When you file your Georgia resident return, Georgia allows a credit for tax paid to New York.
As a result, you avoid double taxation.
However, this mechanism does not eliminate filing requirements. You must still file both returns.

Common Multi-State Mistakes CRNA and N Make
- Not filing required nonresident returns
- Allocating income incorrectly
- Assuming LLC formation controls taxation
- Ignoring reciprocity rules
- Forgetting local taxes such as NYC or Philadelphia
Each mistake increases exposure to penalties and interest.
