Moving from Colorado to Tennessee: Residency, Taxes, and What to Prove

In Colorado

Denver, Colorado Springs, and the Front Range hospital systems make Colorado a significant travel-nurse market. A nurse whose actual domicile is Colorado and who takes Colorado contracts is simply taxed as a resident. A nurse who claims a Colorado tax home while working assignments in other states needs a genuine, regularly used, duplicated-expense Colorado residence; the same indicia list the Department applies to ordinary domicile disputes (driver's license, voter registration, time actually spent) applies to a nurse's claimed tax home, and a thin paper trail risks the same stipend-to-wages reclassification travel nurses face in every state.

In Tennessee

Nashville, Memphis, and Knoxville's hospital systems are active travel-nursing markets, but since Tennessee has no income tax, a travel nurse working a Tennessee contract owes no Tennessee state tax on those wages regardless of tax-home status elsewhere; the nurse's tax exposure runs entirely through whatever state actually claims their tax home and any other income-tax states they work in during the year.

In Colorado

Colorado is home to the Broncos, Nuggets, Rockies, and Avalanche, and nonresident athletes on visiting teams owe Colorado tax on the duty days they spend in the state under standard apportionment against total season duty days. Because Colorado's rate is a flat 4.40% with no separate capital-gains carve-out, the jock-tax math is simpler than in graduated-rate states, but the liability is real and applies to every visiting team that plays a game in Denver.

In Tennessee

Tennessee is home to the Titans (NFL), Grizzlies (NBA), and Predators (NHL), and because the state has no individual income tax, it cannot and does not impose a jock tax on visiting players the way most other franchise states do; Tennessee-based players keep more of their income than a comparable player based in a state like California or New York, since neither their home-team income nor any Tennessee duty days are taxed at the state level (visiting players still may owe tax to their own home state and to other states with jock-tax regimes on away-game duty days, just not to Tennessee).

In Colorado

Colorado's scenario runs in both directions. Wealthy buyers in Aspen, Vail, Telluride, and other mountain resort towns who keep a primary domicile elsewhere need to track aggregate days against the six-month, permanent-place-of-abode threshold, since a leased or owned ski home plainly qualifies as a permanent place of abode. Separately, Colorado's own domiciliaries who spend winters in Arizona or Florida remain presumed Colorado domiciliaries under the regulation's continuing-domicile presumption unless they affirmatively establish a new domicile elsewhere, so simply wintering out of state does not by itself cut Colorado ties.

In Tennessee

Tennessee is not a classic snowbird destination the way Florida or Arizona are, and because it has no income tax, long-term visitors face none of the statutory-residency day-count exposure that snowbirds worry about in states like New York, California, or Hawaii; a person splitting time between Tennessee and a high-tax state should instead focus their planning on that other state's day-count and domicile rules, since Tennessee itself creates no tax trigger.

In Colorado

Colorado has no convenience-of-employer rule: a nonresident performing all work physically outside Colorado for a Colorado-based employer is not Colorado-taxed on those wages solely because the employer is headquartered here. Colorado has been a significant landing spot for remote workers relocating from California, Texas, and the coasts since 2020, and the state has no reciprocal withholding agreements with any other state, so a genuine mid-year move still requires the DR 0104PN part-year split rather than a simple withholding switch.

In Tennessee

A remote worker who relocates to Tennessee and works for an out-of-state employer owes no Tennessee tax on those wages, since there is nothing to tax; any exposure runs entirely through the employer's home state and whether that state applies a convenience-of-the-employer rule to the arrangement, which is the reason many remote workers specifically target no-income-tax states like Tennessee for the move.

In Colorado

Colorado follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. A service member stationed in Colorado on orders does not become a Colorado domiciliary from the posting alone, and neither does an accompanying spouse who elects to keep the service member's home-state domicile under MSRRA. Colorado also offers a military retirement subtraction that interacts with, but does not simply duplicate, the general pension and annuity subtraction.

In Tennessee

Tennessee hosts significant military presence (Fort Campbell straddles the Tennessee/Kentucky line, Arnold Air Force Base, Millington Naval Support Activity), and follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act; since Tennessee has no income tax, SCRA and MSRRA questions here matter mainly for driver's license, vehicle registration, and voting purposes rather than tax liability.

In Colorado

Denver International Airport (DEN) is a major hub for United Airlines and a large Southwest Airlines operation, giving Colorado a meaningful resident and crew-base airline population. Federal law (49 U.S.C. §40116) limits state taxation of air carrier employees to their state of residence and any state where they earn more than 50% of their pay, which matters directly for DEN-based crew who fly national routes.

In Tennessee

Nashville International Airport is a growing Southwest Airlines base and a secondary hub for several carriers; federal law (49 U.S.C. § 40116) limits state taxation of air carrier employees to their state of residence, which is moot for Tennessee-domiciled crew since Tennessee has no income tax to apply to any portion of their wages regardless of how flight time is distributed.
