Moving from Oklahoma to New Hampshire: Residency, Taxes, and What to Prove

In Oklahoma

Oklahoma has significant rural and tribal-affiliated hospital demand for traveling nurses. Oklahoma taxes nonresident wages for work physically performed in the state regardless of where the nurse's claimed tax home is, so a nurse on assignment in Oklahoma files a nonresident Form 511-NR on that income no matter what state they call home, and if the assignment plus other Oklahoma time exceeds 183 days with an in-state abode, the nurse risks being treated as an Oklahoma statutory resident for the year.

In New Hampshire

New Hampshire has no state income tax to complicate a travel nurse's tax-home analysis, which makes it an attractive tax-home state to claim, similar to Florida or Texas, provided the nurse genuinely maintains and returns to a New Hampshire home between assignments under the general IRS tax-home rules (Publication 463). New Hampshire itself publishes no nurse-specific guidance because it has no individual filing requirement to trigger one.

In Oklahoma

The Oklahoma City Thunder is the state's marquee professional franchise, and Oklahoma applies duty-day apportionment to visiting NBA players' income for games and practices held in-state, standard 'jock tax' treatment. Thunder players themselves are Oklahoma residents or nonresidents like any other taxpayer and are taxed on their full salary if domiciled in Oklahoma, or on their Oklahoma duty days if not.

In New Hampshire

New Hampshire has no major professional sports franchises, so it runs no state jock-tax regime of its own, and because it has no income tax, a New Hampshire-domiciled athlete owes zero state tax on the share of income attributable to New Hampshire duty days, unlike a player based in a state that both taxes and credits.

In Oklahoma

Oklahoma is more often an origin state than a snowbird destination, retirees and remote workers commonly winter in Texas or Arizona while keeping an Oklahoma home. Because Oklahoma domicile persists until affirmatively abandoned, a part-year absence alone, even one that clears six months, does not sever Oklahoma residency without genuine steps to establish a new domicile elsewhere; conversely, spending more than 183 days in Oklahoma with a maintained abode there can pull a nominal nonresident back into statutory residency.

In New Hampshire

New Hampshire places no day-count cap on long visitors of its own, since it has no statutory residency test. The exposure runs entirely the other way: someone who claims New Hampshire domicile to escape a high-tax origin state (most commonly Massachusetts) but still spends significant time and keeps a home in that origin state can be taxed there as a statutory resident regardless of the New Hampshire claim.

In Oklahoma

Oklahoma has no convenience-of-the-employer rule. A remote worker's wages are sourced to where the work is physically performed, so someone living in Oklahoma and working remotely for an out-of-state employer owes Oklahoma tax on that income as an Oklahoma resident, while someone who moves away but still occasionally works from Oklahoma can trigger a nonresident filing obligation for those specific days.

In New Hampshire

New Hampshire has no convenience-of-the-employer rule (it has nothing to source, having no income tax). The real friction runs the other direction: a remote worker who moves to New Hampshire but keeps a Massachusetts-based employer needs to confirm Massachusetts is not still asserting Massachusetts-source treatment of the wages under its own COVID-era sourcing rules, which New Hampshire itself challenged (unsuccessfully, at the Supreme Court) on behalf of its residents in 2020-2021.

In Oklahoma

Oklahoma fully exempts military retirement pay from state income tax. Active-duty pay is taxed based on the servicemember's state of legal residence under the SCRA, and a nonresident military spouse can be exempt from Oklahoma withholding on their own income under the Military Spouses Residency Relief Act by filing Form OW-9-MSE with their employer each year they claim the exemption.

In New Hampshire

New Hampshire follows the federal SCRA and MSRRA: a service member's home-of-record does not change solely because military orders station them in New Hampshire, and an accompanying spouse can generally elect the service member's domicile state under MSRRA. Because New Hampshire taxes no individual income, choosing it as home-of-record eliminates state income tax on military pay entirely.

In Oklahoma

Tulsa is home to American Airlines' largest maintenance and engineering base, but those are ground/MRO employees, not flight crew, so the federal Mobile Workforce carve-out for air carrier crew members (49 U.S.C. Sec. 40116) does not apply to them; their wages are sourced under ordinary multistate employee rules based on where they physically work, which for Tulsa-based maintenance staff is generally all in Oklahoma.

In New Hampshire

New Hampshire has no major hub airport for airline crew, but the federal carve-out (49 U.S.C. § 40116, taxing crew wages only in the state of residence or a state where over 50% of pay is earned) combined with New Hampshire's lack of any income tax makes it, like Florida and Texas, a common domicile choice for crew based at nearby Boston Logan who want to avoid Massachusetts income tax on their wages.
