Moving from Illinois to Hawaii: Residency, Taxes, and What to Prove
Illinois's 4.95% (flat) top income tax rate becomes 11.00% in Hawaii. This move trades a lighter tax environment for a heavier one, so timing income around the transition year matters.
Residency Tests Side by Side
Illinois does not use a simple day-count threshold; it applies a facts-and-circumstances test instead. Hawaii's statutory residency test uses a 200-day threshold.
| Factor | Illinois | Hawaii |
|---|---|---|
| Statutory Residency Test | Illinois has no statutory residency test of the New York or Minnesota type: no bright-line day count and no permanent place of abode prong. 35 ILCS 5/1501(a)(20)(A) defines a resident as an individual '(i) who is in this State for other than a temporary or transitory purpose during the taxable year; or (ii) who is domiciled in this State but is absent from the State for a temporary or transitory purpose during the taxable year.' Those are the only two routes to Illinois residency for an individual. Cain v. Hamer, 2012 IL App (1st) 112833, shows how far that departure from a day count runs: snowbird retirees who spent 1,666 days in Illinois against 1,700 in Florida across 1996 through 2004, an average well above 183 Illinois days a year, were held not to be Illinois residents. Day counts matter in Illinois as evidence of purpose and as inputs to the administrative presumptions, not as a threshold that decides residency by itself. | A Hawaii resident is (1) every individual domiciled in Hawaii, and (2) every other individual, whether domiciled in Hawaii or not, who resides in Hawaii for other than a temporary or transitory purpose. An individual domiciled outside Hawaii is presumed to be a resident if they spend more than 200 days in Hawaii during the taxable year; that presumption can be overcome with evidence satisfactory to the Department that the individual maintained a permanent place of abode outside the state and was in Hawaii only temporarily or transitorily. |
| Domicile Test | Illinois follows the traditional common-law domicile standard under 86 Ill. Adm. Code 100.3020: domicile is the place a person intends as their true, fixed, permanent home, and to which they intend to return whenever absent. A person can have only one domicile at a time, and it continues until a new one is established through both physical presence in the new location and demonstrated intent to abandon Illinois as the permanent home. The Department of Revenue looks at where a person votes, holds a driver's license and registers vehicles, banks, keeps professional relationships (doctor, lawyer, accountant), works, houses family, and belongs to clubs or religious institutions; no single factor controls. | Hawaii defines domicile as the place where an individual has a true, fixed, permanent home and principal establishment, and to which, whenever absent, they intend to return. Three things are necessary to create a new domicile: first, abandonment of the old domicile; second, the intent to establish a new one; and third, actual physical presence in the new location. Once a domicile is established, the intent to abandon it alone is not sufficient, a new domicile must actually be shown. Marrying a nonresident does not by itself change a Hawaii resident's domicile status if the three-part test for changing domicile is not independently met. |
| Day Count Threshold | No fixed threshold | 200 days |
| Any Part of a Day Rule | Not applicable in the statutory sense, because Illinois has no day-count threshold for an individual to cross. There is no any-part-of-a-day rule to apply. Days still get counted in Illinois practice, both because 86 Ill. Adm. Code 100.3020(f) presumes residency above nine months in the aggregate and presumes continued residency where an individual is present in Illinois more days than in any other state, and because the Department of Revenue's audit division reconstructs presence from credit card, toll, and travel records to test whether time in Illinois was temporary or transitory. | The Department's guidance describes the threshold in terms of days spent in Hawaii during the taxable year rather than explicit any-part-of-a-day language; no published Hawaii-specific carve-out for medical emergencies or connecting travel was located in this research pass, so the safer planning assumption is that any day with Hawaii presence counts toward the 200-day figure, consistent with how most states treat statutory day counts. |
| Presumptions | 86 Ill. Adm. Code 100.3020(f) supplies four rebuttable presumptions in place of a statutory day test. An individual who spends in the aggregate more than nine months of any taxable year in Illinois is presumed to be a resident. An individual absent from Illinois for one year or more is presumed to be a nonresident. An individual receiving a homestead exemption on Illinois property under 35 ILCS 200/15-175 is presumed to be an Illinois resident. And an Illinois resident in one year is presumed to be a resident the following year 'if he or she is present in Illinois more days than he or she is present in any other state.' The presumptions 'are not conclusive and may be overcome by clear and convincing evidence to the contrary,' with the rule listing acceptable rebuttal evidence including location of spouse and dependents, voter and vehicle registration, driver's license, filing a resident return elsewhere, home ownership or rental agreements, the permanent or temporary nature of work assignments, location of professional licenses, location of medical providers, accountants and attorneys, club memberships and participation, and telephone or other utility usage over a duration of time. | More than 200 days of physical presence in Hawaii during the taxable year creates a rebuttable presumption of Hawaii residency for someone domiciled elsewhere. |

Leaving Illinois
Illinois is not in the top tier of aggressive exit-audit states the way New York or California are, but the Department of Revenue does examine departing high earners, especially where a large capital gain or business sale occurred near the claimed move date, or where the taxpayer kept an Illinois home, spouse, or business presence after claiming nonresidency. Auditors reconstruct day counts using credit card statements, toll records, airline records, and utility usage, and they cross-check the General Homestead Exemption against a claimed out-of-state domicile.
Trailing Income
Illinois does not have a convenience-of-the-employer rule, so a former resident who telecommutes for an Illinois employer from another state generally is not taxed by Illinois on those wages solely because the employer is based in Illinois; sourcing follows where the work is actually performed. Illinois does tax nonresident income that is Illinois-source, including compensation for services actually performed in Illinois, gain on the sale of Illinois real property, and a departing resident's share of Illinois business income allocated under the state's apportionment rules for the period they were still a resident or doing business in the state.
Part-Year Filing
Form IL-1040 together with Schedule NR, Nonresident and Part-Year Resident Computation of Illinois Tax, is used for the year someone moves into or out of Illinois. Schedule NR allocates income between the Illinois-resident portion of the year and the nonresident portion, and computes an Illinois tax based only on Illinois-source and Illinois-period income.
Enforcement Methods
Common Exit Mistakes
Establishing Hawaii Residency
| Action | Agency | Deadline |
|---|---|---|
| Obtain a Hawaii driver's license | County Department of Customer/Motor Vehicle Services (Honolulu, Maui, Hawaii, or Kauai County, whichever applies) | commonly cited as 30 days after establishing residency in secondary guidance; this research pass could not confirm a single statewide statutory deadline from a primary county or state source, since each county administers licensing separately |
| Register and title vehicles | County motor vehicle registration office | commonly cited as 30 days after establishing residency; not independently confirmed against a primary county source in this research pass |
| Register to vote | Hawaii Office of Elections | online registration available anytime at olvr.hawaii.gov; paper applications must reach the county Elections Division by the deadline set for each specific election (July 29, 2026 for the 2026 primary, October 26, 2026 for the 2026 general) |
| File the county home exemption on real property (if a homeowner) | County Real Property Assessment Division | varies by county; commonly September 30 of the year before the exemption year |
Declaration of Domicile
Hawaii has no Florida-style recorded Declaration of Domicile. The Department of Taxation's own definition requires three elements to establish a new domicile: abandoning the old one, intending to establish the new one, and actually being physically present in Hawaii, proven through conduct (driver's license, vehicle registration, voter registration, lease or deed, and time actually spent in the islands) rather than a single filed document.
Homestead
Hawaii's property tax relief is the county-administered 'home exemption,' available to an owner who occupies the property as their principal residence, with the exempted amount and filing deadline varying by county (Honolulu's is among the better-documented, filed with the Real Property Assessment Division). Because it requires a sworn declaration of principal residence, filing it functions as dated, county-recorded evidence of Hawaii domicile, similar in evidentiary role to homestead filings elsewhere even though Hawaii's exemption is comparatively small given the state's already very low 0.29% effective property tax rate.
Voter Registration
Register online anytime through the Office of Elections' portal (https://olvr.hawaii.gov/), or by paper application to your county Elections Division; paper deadlines are set per election (July 29, 2026 for the 2026 primary; October 26, 2026 for the 2026 general).
Vehicle Registration Deadline
30 days
New Resident Tax Traps
New residents are taxed as full Hawaii residents on worldwide income from the date domicile is established, filed via Form N-15's part-year mechanism for the year of the move; the more common trap is on the retirement-income side, arrivals assume Hawaii's full pension exemption extends to 401(k) and IRA withdrawals, when in fact only true employer pensions and Social Security are exempt and retirement account distributions are fully taxable at rates up to 11%.
What Changes on Tax
Illinois Top Rate
4.95% (flat)
Hawaii Top Rate
11.00%
Moving from Illinois to Hawaii raises the top marginal income tax rate from about 4.95% to about 11%, an increase of roughly 6.05 percentage points.
Withholding Reciprocity
Illinois and Hawaii do not have a wage-withholding reciprocity agreement with each other, so this move follows ordinary source-state and resident-state filing rules rather than a reciprocity exception.
Community Property Transition
Illinois and Hawaii both use common law, equitable-distribution marital property rules, so no community property transition applies to this move.
Beyond Income Tax
Illinois
Capital gains: No preferential rate. Capital gains are taxed as ordinary income at the same 4.95% flat rate as wages.
Estate or inheritance tax: Illinois has an estate tax with a $4 million exemption per estate that is not indexed for inflation and is not portable between spouses. Rates are graduated from roughly 0.8% up to 16% on the amount above the exemption. There is no separate inheritance tax.
Property tax: Illinois has the highest statewide effective property tax rate in the country, around 1.92% of home value, more than double the national median. The General Homestead Exemption reduces the taxable assessed value of an owner-occupied principal residence by up to $10,000 in Cook County, $8,000 in counties bordering Cook, and $6,000 elsewhere.
Sales tax: State base rate is 6.25%, but local home-rule and county taxes push combined rates as high as 11.5% in parts of Cook, Kane, and Warren counties; the effective statewide average is closer to 8.9%.
Hawaii
Capital gains: Hawaii taxes capital gains, but at a capped rate of 7.25% for individuals rather than as fully ordinary income, which softens the blow for residents selling appreciated assets even though the top wage-income rate is 11%.
Estate or inheritance tax: Hawaii has its own state estate tax, separate from the federal estate tax. The 2026 exemption is $5.49 million per person (roughly $10.98 million portable for a married couple), with tax on the excess ranging from 10% up to 20% on amounts more than $10 million above the exemption. There is no separate inheritance tax.
Property tax: Effective property tax rate on owner-occupied housing is about 0.29%, the lowest in the nation, offsetting Hawaii's otherwise very high cost of living and high income tax rates. Each of the four counties (Honolulu, Maui, Hawaii, Kauai) administers its own real property tax with its own home exemption amount and filing deadline, so the exemption mechanics are not uniform statewide.
Sales tax: Hawaii has no traditional sales tax; it levies a General Excise Tax (GET) on businesses' gross receipts, typically passed through to consumers, at a 4% state rate (4.5% on Oahu due to a county surcharge), for an average combined rate around 4.5%, one of the lowest nominal rates in the country though the GET's broader base (it applies to services and rent, not just goods) means the effective consumer burden is often understated by the headline rate.
Who This Move Applies To
Travel Nurses
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 Hawaii
Hawaii is a persistently high-demand travel nursing market given chronic staffing shortages on the neighbor islands, and a nurse working Hawaii contracts needs to track cumulative Hawaii days against the 200-day presumption threshold if Hawaii is not their claimed tax home; a nurse stacking consecutive Hawaii assignments can cross 200 days within a taxable year and face a Hawaii residency presumption they then have to rebut with proof of a genuine tax home and permanent abode elsewhere.
Professional Athletes
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 Hawaii
Hawaii has no major professional sports franchise subject to jock-tax duty-day apportionment in the way NBA, NFL, or MLB markets are; college and exhibition events held in Hawaii (such as preseason NFL games or college football's opening games) can still create Hawaii-source income for visiting teams' employees under the state's general nonresident sourcing rules, though this is a minor and infrequent exposure compared to states with resident franchises.
Snowbirds, Long Visitors, and RVers
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 Hawaii
Hawaii is a snowbird destination rather than a snowbird-exit state, which flips the usual dynamic: a mainland resident who keeps a Hawaii condo and winters there for a few months a year needs to watch the 200-day presumption threshold, since exceeding it shifts the burden onto them to prove they maintained a permanent abode and tax home on the mainland and were in Hawaii only temporarily. This is a materially lower bar to trip than New York's 183-day or California's facts-and-circumstances test, and long-stay visitors who rent out their mainland home while wintering in Hawaii should be especially careful about the 'permanent place of abode elsewhere' evidence.
Remote Workers
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 Hawaii
Hawaii has no convenience-of-the-employer rule; a remote worker physically performing work from Hawaii for an out-of-state employer generally owes Hawaii tax on that Hawaii-source income under ordinary physical-presence sourcing, and does not separately owe the employer's home state tax on those wages unless that state applies its own convenience rule, which is the scenario Hawaii arrivals from states like New York need to watch for in their employer's withholding treatment.
Military
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 Hawaii
Hawaii has one of the largest active-duty military populations of any state (Pearl Harbor-Hickam, Schofield Barracks, Marine Corps Base Hawaii), and follows SCRA and MSRRA: a servicemember posted to Hawaii on orders does not become a Hawaii domiciliary solely from the posting, and under MSRRA as amended in 2018 and 2022, a spouse can generally elect the servicemember's state of legal residence, or either party can elect to use the servicemember's residence, for state tax purposes regardless of when or where the marriage occurred. A Hawaii-resident spouse relocating with a servicemember on a permanent-change-of-station transfer without intent to make the new location permanent does not lose Hawaii domicile under the Department's own published examples.
Airline Crew
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.
In Hawaii
Honolulu's Daniel K. Inouye International Airport is a major Pacific hub for Hawaiian Airlines and a stopover point for trans-Pacific carriers, so Hawaii has a resident airline crew population. Federal law (49 U.S.C. § 40116) limits state taxation of air carrier employees to their state of residence and, in limited cases, a state where more than 50% of pay is earned; Hawaii-domiciled crew are taxed on their full wages at Hawaii's rates regardless of how flight time is split across other states.
Tools for This Move
Illinois to Hawaii FAQ
Does Illinois have a 183-day rule like New York or Minnesota?+
No. This is the single most common misconception about Illinois residency. 35 ILCS 5/1501(a)(20) contains no day-count threshold and no permanent place of abode prong; a resident is someone in Illinois for other than a temporary or transitory purpose, or an Illinois domiciliary absent for a temporary or transitory purpose. What Illinois has instead are the rebuttable presumptions in 86 Ill. Adm. Code 100.3020(f), including a presumption of residency above nine months in the aggregate and a presumption that a prior-year resident remains one if present in Illinois more days than in any other state. The practical difference is real in both directions: crossing 183 Illinois days does not by itself make you a resident, and staying under 183 does not by itself make you a nonresident.
I only spent a few months in Hawaii but I own a condo here. Am I a Hawaii resident for tax purposes?+
Not automatically, but watch the 200-day threshold. If you're domiciled elsewhere and spend more than 200 days in Hawaii during the taxable year, the Department of Taxation presumes you're a Hawaii resident; you'd need evidence you maintained a permanent place of abode outside Hawaii and were in the islands only temporarily to overcome that presumption. Under 200 days, the presumption doesn't apply and your out-of-state domicile controls.
If I move to Florida but keep my Chicago condo, will Illinois still tax me?+
Keeping the condo does not by itself make you taxable, because Illinois has no permanent place of abode test that a retained condo could trigger. The risk runs through purpose and presumptions instead. If you spend more than nine months of the year in Illinois, or simply more days there than in any other state after a year as an Illinois resident, the Department gets a presumption of residency you can rebut only by clear and convincing evidence. Continuing to claim the General Homestead Exemption on the condo is worse than the condo itself, since that alone creates its own presumption of Illinois residency and is a cross-check Illinois auditors run directly against a claimed out-of-state domicile.
Does Hawaii tax my Social Security or pension?+
Social Security is fully exempt, and so are qualified public and private pensions from an employer-funded plan. What isn't exempt is money you pull from a 401(k) or IRA, that's fully taxable as ordinary income at Hawaii's rates, which top out at 11%. Retirees relying on a traditional pension and Social Security do much better here tax-wise than retirees drawing mainly from retirement accounts.
Does Illinois have a convenience-of-the-employer rule for remote workers?+
No. Illinois sources employee wages to where the work is physically performed, not to where the employer is headquartered. A nonresident who works remotely from another state for a Chicago-based employer generally is not taxed by Illinois on those wages, which is a meaningful difference from convenience-rule states like New York, and it means remote workers face less Illinois exposure after moving away than they might expect.
Does Hawaii have an estate tax?+
Yes, Hawaii is one of the minority of states with its own estate tax separate from the federal one. The 2026 exemption is $5.49 million per person, roughly $10.98 million for a married couple with portability, with rates from 10% up to 20% on the amount above the exemption. There's no separate inheritance tax.
How do I file my Illinois taxes for the year I move out of state?+
File Form IL-1040 together with Schedule NR, the Nonresident and Part-Year Resident Computation of Illinois Tax. Schedule NR splits your income between the period you were an Illinois resident, which is taxed in full, and the period after you became a nonresident, when only Illinois-source income is taxed. Skipping Schedule NR and simply filing as a full-year nonresident in your move year is a common and easily flagged mistake.
My spouse is active duty and got transferred to Hawaii. Do I become a Hawaii resident?+
Not automatically. Under the Military Spouses Residency Relief Act, if your servicemember spouse is in Hawaii solely on military orders and you're in Hawaii solely to be with them, you can generally keep your prior state of domicile, or elect to use your spouse's, for state tax purposes, and income you earn from services performed in Hawaii can be exempt from Hawaii tax under those conditions.
I work in Illinois but live in Wisconsin. Do I have to file two state returns?+
Illinois has reciprocity with Wisconsin, Iowa, Kentucky, and Michigan, so a Wisconsin resident working in Illinois generally does not owe Illinois tax on those wages and should not have Illinois tax withheld; instead, only Wisconsin taxes that income. If Illinois tax was withheld in error, you file for a refund from Illinois rather than claiming a credit, and you report the income on your Wisconsin return as usual.
What form do I file for the year I move to or from Hawaii?+
Form N-15, Individual Income Tax Return for Nonresidents and Part-Year Residents, reporting worldwide income for the period you were a Hawaii resident and only Hawaii-source income for the nonresident portion of the year. Full-year residents file Form N-11 instead.
Will keeping the homestead exemption on my Illinois house hurt me if I claim Florida residency?+
Yes, it's a direct contradiction auditors specifically look for. The General Homestead Exemption requires the property to be your owner-occupied principal residence as of January 1, so continuing to receive it while filing as an Illinois nonresident and claiming Florida domicile undercuts your own position. If you've genuinely moved, removing the exemption is one of the concrete steps that supports your new domicile claim.
I'm a travel nurse working consecutive Hawaii contracts. Could I become a Hawaii tax resident by accident?+
Yes, if your cumulative Hawaii days for the taxable year exceed 200, the Department presumes you're a Hawaii resident regardless of your claimed tax home elsewhere, and the burden shifts to you to prove you kept a permanent place of abode outside Hawaii and were only there temporarily. Track your Hawaii day count across all your contracts for the year, not just one assignment.
