Moving from Louisiana to Washington: Residency, Taxes, and What to Prove

In Louisiana

Louisiana's hospital systems in New Orleans and Baton Rouge draw significant travel-nurse staffing, and Louisiana taxes nonresident wages for work physically performed in the state regardless of the nurse's claimed tax home elsewhere, requiring a nonresident IT-540B on those wages. A nurse whose combined time in Louisiana across contracts exceeds six months while maintaining a place to stay risks the statutory-residency test pulling them into full resident status for the year.

In Washington

Seattle-area hospital systems are a major travel nursing market. Because Washington has no general wage income tax, a genuine Washington tax home creates no state income tax exposure on stipends or wages earned in Washington, though nurses still owe nonresident tax in every other income-tax state where they take assignments. The same tax-home substantiation rules apply: an actual, regularly used residence with duplicated living expenses, not just a mailing address.

In Louisiana

The New Orleans Saints (NFL) and New Orleans Pelicans (NBA) are Louisiana's major professional franchises. Louisiana taxes nonresident athletes and entertainers on income allocated to duty days or performances in the state, the standard jock-tax structure, while Louisiana-domiciled players on those teams are taxed on their full salary as residents, subject to credits for tax paid to other states on road games.

In Washington

The Seahawks, Mariners, Sounders, and Kraken are all based in Washington, and for decades Washington's lack of a personal income tax made contracts here worth more after-tax than identical contracts in California or New York, since athletes owed no state tax on the home-state portion of their income. That advantage has a hidden cost: because Washington historically had no income tax, athletes domiciled here got no tax credit to offset the jock tax other states charged them for road games, making those out-of-state payments a pure additional cost rather than an offset against home-state liability. The 2028 Millionaires' Tax will itself begin reaching a portion of highly paid athletes' income domiciled in Washington.

In Louisiana

Louisiana's statutory six-month-plus-abode test is the practical trap for long visitors: someone who splits time between a Louisiana camp or second home and another state can be pulled into full Louisiana residency simply by crossing 183 days while maintaining that Louisiana abode, regardless of where they consider themselves domiciled. Post-hurricane displacement (evacuation for Katrina, Ida, and similar storms) has also raised genuine questions about whether temporary out-of-state sheltering interrupts domicile; the general rule is that involuntary, temporary displacement does not by itself establish a new domicile or abandon the Louisiana one.

In Washington

The relevant test for a long-term visitor isn't Washington's general tax system, since there is none for ordinary wages, but the 183-day physical-presence-plus-abode test and the 30-day safe harbor under the capital gains excise tax. Someone who keeps a Washington vacation home and visits often needs to track their day count carefully if they have appreciated stock or other intangible property they might sell, since crossing 183 days while maintaining a Washington abode can make them a Washington resident for that tax even without ever forming domiciliary intent.

In Louisiana

Louisiana has no convenience-of-the-employer rule; wages are sourced to where the work is physically performed. A Louisiana resident working remotely for an out-of-state employer owes Louisiana tax on that income as a resident, and someone who leaves Louisiana but still works occasional in-state days can owe nonresident tax on just those days.

In Washington

Washington has no convenience-of-employer rule and, until 2028, no general wage income tax at all, making it one of the most attractive states for remote workers regardless of where their employer is based. The capital gains excise tax and the incoming Millionaires' Tax are the only state-level income taxes that reach a remote worker's earnings, and both turn primarily on domicile rather than employer location.

In Louisiana

Louisiana fully exempts military retirement pay from state income tax. Active-duty pay follows the servicemember's SCRA state of legal residence, and a nonresident military spouse in Louisiana solely due to the servicemember's orders can generally avoid Louisiana tax on their own income under the Military Spouses Residency Relief Act, provided they share the same non-Louisiana domicile as the servicemember.

In Washington

Washington follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. Naval Base Kitsap and Joint Base Lewis-McChord are major installations, and because Washington has no general wage income tax, service members and spouses electing Washington domicile under MSRRA owe no state tax on military pay or spousal wage income today.

In Louisiana

Louisiana has no major airline hub or flight-crew domicile base comparable to Dallas-Fort Worth or Atlanta; Louis Armstrong New Orleans International is served by multiple carriers but is not a crew base of national significance, so the federal Mobile Workforce carve-out for air carrier employees has limited practical relevance for Louisiana residents specifically.

In Washington

Seattle-Tacoma International Airport (SEA) is a major hub and crew base for Alaska Airlines and Delta. Federal law (49 U.S.C. §40116) limits taxation of air carrier employees to their state of residence and any state where they earn more than 50% of pay; because Washington has no general wage income tax, Washington-based crew owe no state tax on their wages today regardless of this federal carve-out, though the 2028 Millionaires' Tax may eventually intersect with it for the highest earners.
