Moving from Georgia to Illinois: Residency, Taxes, and What to Prove

In Georgia

Georgia is a large travel-nursing assignment market (Atlanta, Augusta, Savannah systems), so travel nurses working Georgia contracts need to track Georgia days against the 183-day aggregate test if Georgia is not their claimed tax home; a nurse who works consecutive Georgia contracts can inadvertently cross 183 days in a rolling 365-day window and become a Georgia taxable resident even while maintaining a tax home elsewhere.

In Illinois

Illinois has no statutory day-count test to trip, so a travel nurse not domiciled in Illinois does not become an Illinois resident merely by crossing a day threshold on a long assignment. What creates exposure instead is the temporary or transitory question and the 100.3020(f) presumptions: an assignment structured as a series of renewals that keeps a nurse in Illinois more than nine months of a year, or more days than in any other state, supports a presumption of residency that must be rebutted by clear and convincing evidence, and the permanent or temporary nature of the work assignment is named in the rule as relevant evidence. The more common Illinois exposure is the reverse pattern, where a nurse claims a Florida or Texas tax home but actually lives in and pays Illinois-area rent for most of the year; Illinois-source wages for days actually worked in Illinois are taxable to any nonresident nurse regardless of claimed tax home.

In Georgia

Atlanta is home to the Braves (MLB), Falcons (NFL), Hawks (NBA), and Atlanta United (MLS); visiting players on these teams' opponents owe Georgia nonresident tax apportioned by duty days spent in Georgia for games, practices, and team activities, following the standard multistate jock-tax duty-day framework used across the major leagues. Georgia-based players are taxed on their full income under the state's flat 4.99% rate, with credits for tax paid to other states on away-game income.

In Illinois

Illinois taxes nonresident professional athletes on a duty-day basis: Illinois-source income equals total compensation multiplied by the ratio of duty days in Illinois (games, practices, mandatory team functions) to total duty days for the season; mere travel through Illinois without a game or team event does not create a duty day. This applies to visiting teams playing the Bears, Bulls, Blackhawks, White Sox, and Cubs, and Illinois is regarded by practitioners as an aggressive, well-enforced jock-tax state that historically extended the tax reciprocally to any state that taxed Illinois-based athletes.

In Georgia

Georgia's climate and cost of living pull snowbirds from colder high-tax states, but the 183-day aggregate rule is unforgiving: a part-year visitor who spends more than 183 days or part-days in Georgia within a trailing 365-day period is taxed as a full Georgia resident regardless of stated domicile elsewhere, which is the opposite direction of the more commonly discussed New York or California statutory-resident traps but works on the same day-count mechanics.

In Illinois

The Illinois snowbird risk runs entirely through the 100.3020(f) presumptions, not through a day threshold. A retiree who keeps the Illinois house and spends more than nine months there risks the nine-month presumption of residency, and a former Illinois resident is presumed to still be one in the following year if present in Illinois more days than in any other state, which is a comparison a snowbird splitting a year can lose well short of any traditional threshold. The favorable counterweight is Cain v. Hamer, 2012 IL App (1st) 112833, where retirees who split time nearly evenly (1,666 Illinois days against 1,700 Florida days across 1996 through 2004) were held nonresidents, with the court weighing nexus evidence such as Florida licenses, voter registration, a Florida declaration of domicile, club spending, and credit card data showing 73% of expenditures and 61% of transactions outside Illinois. Illinois's General Homestead Exemption is a specific cross-check point if a person claims Florida domicile but keeps the Illinois exemption active.

In Georgia

Georgia has no convenience-of-the-employer rule; a remote worker physically performing work from Georgia for an out-of-state employer generally owes Georgia tax on that Georgia-source income regardless of where the employer is headquartered, and does not owe the employer's home state tax on those same wages absent that state's own convenience rule (which is why Georgia arrivals from convenience-rule states like New York need to watch their employer's withholding treatment closely).

In Illinois

Illinois has no convenience-of-the-employer rule. A nonresident who works remotely from another state for an Illinois-based employer is generally not taxed by Illinois on those wages, because Illinois sources employee compensation to where the services are physically performed, not to the employer's location. This makes Illinois meaningfully less sticky for remote workers than New York or a handful of other convenience-rule states.

In Georgia

Georgia follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act: a servicemember stationed in Georgia on orders does not become a Georgia domiciliary solely because of the posting, and an MSRRA-eligible spouse can generally retain the servicemember's state of legal residence. Georgia also exempts military retirement income from state tax for many veterans under age-based provisions layered on top of the general retirement income exclusion.

In Illinois

Illinois follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. A servicemember whose home of record is Illinois remains an Illinois domiciliary for tax purposes regardless of duty station unless they take affirmative steps to change domicile, while a servicemember stationed in Illinois on orders, and their qualifying spouse, does not become an Illinois resident solely because of the posting, and military pay is not Illinois-source income for a nonresident servicemember stationed there.

In Georgia

Atlanta's Hartsfield-Jackson is Delta Air Lines' largest hub, so Georgia has a large resident and commuting airline-crew population. Federal law (49 U.S.C. § 40116) limits state taxation of air carrier employees to their state of residence and, in narrow cases, a state where they earn more than 50% of pay; crew domiciled in Georgia are taxed on their full wages at Georgia's flat rate regardless of how their flight time is distributed across other states.

In Illinois

Federal law (49 U.S.C. §40116) limits states to taxing airline employee compensation only in the employee's state of residence and any state where more than 50% of pay is earned. This protects flight crew based at O'Hare or Midway who are domiciled outside Illinois from having their full compensation pulled into Illinois taxation solely because their duty station is in Illinois.
