Moving from Illinois to Florida: Residency, Taxes, and What to Prove
The top income tax rate drops from 4.95% (flat) in Illinois to 0% in Florida. Establishing Florida residency correctly is what protects that benefit.
Residency Tests Side by Side
Neither Illinois nor Florida relies on a simple statutory day-count threshold. Both apply a facts-and-circumstances or closest-connections style test, so day counting alone will not settle a residency question in either direction.
| Factor | Illinois | Florida |
|---|---|---|
| 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. | None. Because Florida imposes no personal income tax, it has no statutory day-count residency test, no 'permanent place of abode plus 183 days' rule, and no state tax return that turns on residency status. Florida residency status matters legally for homestead, probate/domicile, and asset-protection law, not for an income-tax trigger. |
| 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. | Florida common law and Fla. Stat. § 222.17 define domicile as the place where a person maintains a permanent home with the present intent to remain indefinitely and to return whenever absent. There is no published multi-factor weighting test the way New York or California use; Florida courts and the probate/homestead context look at physical presence, a declaration of domicile, voter registration, driver's license, homestead filing, and where the person actually spends time, but no state revenue agency runs a residency-factor audit because there is no income tax to trigger one. |
| Day Count Threshold | No fixed threshold | No fixed threshold |
| 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. | Not applicable; Florida has no day-count residency test of its own. Florida day counts only matter for the OTHER state's statutory residency test when someone claims Florida domicile but keeps a home and spends significant time in a high-tax origin state. |
| 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. | None published |

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 Florida Residency
| Action | Agency | Deadline |
|---|---|---|
| File a Declaration of Domicile | Clerk of the Circuit Court (county of residence) | no deadline, but do it immediately upon establishing a permanent home |
| Get a Florida driver license | Florida Department of Highway Safety and Motor Vehicles (FLHSMV) | within 30 days of establishing residency |
| Register vehicles and obtain Florida auto insurance | FLHSMV / county tax collector | within 10 days of establishing residency |
| Register to vote | Florida Division of Elections / county Supervisor of Elections | no deadline to establish residency; must register at least 29 days before voting in a given election |
| File for homestead exemption | County Property Appraiser | by March 1 of the tax year to get that year's exemption; must own and occupy as of January 1 |
Declaration of Domicile
Florida is one of the few states with a formal, purpose-built domicile filing: a sworn one-page statement under Fla. Stat. § 222.17, notarized and recorded with the Clerk of the Circuit Court in the county of residence for about a $10 recording fee. It states the person's prior domicile, Florida county, and the date Florida became home, and it is routinely cited in other states' residency audits as one data point (not dispositive on its own) supporting a genuine domicile change.
Homestead
The homestead exemption reduces assessed value by up to $50,000 (the first $25,000 applies to all taxing authorities including schools; the second $25,000, on value between $50,000 and $75,000, excludes school levies) and, more importantly for audit defense, requires proof of permanent residency as of January 1: Florida driver's license, voter registration, and vehicle registration all showing the homestead address, plus proof the applicant is not also claiming a residency-based tax benefit in another state. This filing is one of the strongest pieces of objective evidence in a domicile-change file because it is a sworn statement made to a government body with penalties for fraud, but appraisers actively cross-check it against out-of-state filings and DMV/voter records.
Voter Registration
Register through RegisterToVoteFlorida.gov, in person at a tax collector's office, or when renewing a Florida driver license; no deadline to register itself, but registration must be at least 29 days before a given election to vote in it (https://registertovoteflorida.gov/).
Vehicle Registration Deadline
10 days
New Resident Tax Traps
Because there is no state income tax, the main trap is not a Florida tax at all: it's leaving too thin a Florida evidence trail (no Declaration of Domicile, no homestead, driver's license obtained but the person still spends 200+ days a year in New York) while assuming the move is already complete. New York, California, and other origin states treat a Florida address with weak day-count and home-use evidence as a paper move, not a real one, and tax the person as a full-year resident anyway.
What Changes on Tax
Illinois Top Rate
4.95% (flat)
Florida Top Rate
0%
Moving from Illinois to Florida drops the top marginal income tax rate from about 4.95% to about 0%, a reduction of roughly 4.95 percentage points.
Withholding Reciprocity
Illinois and Florida 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 Florida 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%.
Florida
Capital gains: Not taxed. Florida has no personal income tax, so there is no separate capital gains treatment to plan around at the state level; only federal capital gains tax applies once you are a bona fide Florida resident.
Estate or inheritance tax: None. Florida repealed its estate tax when the federal state death tax credit was phased out and has no separate inheritance tax; only the federal estate tax (currently applying above the federal exemption) can apply to a Florida domiciliary's estate.
Property tax: Average effective rate is about 0.86% statewide, but the Save Our Homes cap limits annual assessed-value growth on homesteaded property to the lesser of 3% or the CPI change (2.7% for 2026), and up to $500,000 of that accumulated benefit is portable to a new Florida homestead within two years of leaving the old one.
Sales tax: 6% state rate; counties may add a discretionary surtax of roughly 0.5% to 2%, producing a combined average of about 7% depending on county.
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 Florida
Florida is the most common 'tax home' state travel nurses claim to receive tax-free stipends, but IRS and state auditors have disallowed Florida tax-home claims for nurses who kept a Florida address on paper while actually living year-round in Ohio or another assignment-state rental and never returning to Florida. To hold up, the nurse needs to actually maintain and return to the Florida home between assignments, keep paying for it continuously, and hold Florida driver's license, voter registration, and vehicle registration, not just a mailing address.
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 Florida
Florida is home to the Miami Heat, Miami Dolphins, Tampa Bay Buccaneers, Tampa Bay Lightning, Florida Panthers, Orlando Magic, Miami Marlins, and Tampa Bay Rays. Players on these teams owe zero state tax on the roughly half of duty days spent in Florida, but every state jock tax on duty days in taxing states (California, New York, etc.) still applies in full, and because Florida has no income tax, there is no Florida credit to offset those away-state bills, unlike a player based in a state that both taxes and grants an out-of-state tax credit.
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 Florida
Florida itself places no day-count cap on how long a part-year resident can be in-state; the exposure runs the other direction; the origin state (New York, Connecticut, New Jersey) is the one counting days and evaluating whether the Florida home is a genuine primary residence or a seasonal one. A Florida-domiciled snowbird who spends more than 183 days in New York, with a permanent place of abode there, can still be taxed as a New York statutory resident despite the Florida homestead and driver's license.
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 Florida
Florida has no convenience-of-the-employer rule and nothing to reciprocate, since it has no income tax to source wages against. The risk for a remote worker moving to Florida is entirely on the origin-state side: if the employer is based in New York and treats the employee as still NY-sourced under NY's convenience rule, the worker can owe New York tax on Florida-earned wages regardless of Florida residency.
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 Florida
Florida follows the federal Servicemembers Civil Relief Act (SCRA) and Military Spouses Residency Relief Act (MSRRA): a servicemember's home-of-record state of legal residence does not change solely due to military orders stationing them in Florida, and a spouse can generally elect the servicemember's domicile state under MSRRA. Because Florida has no income tax, choosing Florida as home-of-record eliminates state income tax on military pay entirely, which is why Florida is a common home-of-record choice among active-duty service members.
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 Florida
Federal law (49 U.S.C. § 40116) restricts states from taxing air carrier employees' wages except by their state of residence and, in limited cases, the state where they earn more than 50% of their pay. Because Florida has no income tax, crew members domiciled in Florida owe no state tax on their airline wages regardless of how their duty time is split, which is why Florida (along with Texas) is a common domicile choice for pilots and flight attendants based in Miami, Fort Lauderdale, or Orlando.
Tools for This Move
Illinois to Florida 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.
If I get a Florida driver's license and file a Declaration of Domicile, is my New York tax residency automatically over?+
No. New York evaluates domicile and statutory residency independently of any paperwork filed in Florida. A Declaration of Domicile and Florida license are supporting evidence, but New York's Nonresident Audit Guidelines weigh where your home, business, family, and time actually are; if you still spend more than 183 days in New York with a place there to stay, you can be taxed as a New York statutory resident regardless of your Florida filings.
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.
Do I have to file a Florida tax return once I move here?+
No. Florida has no personal income tax, so there is no individual return to file, part-year or otherwise. The filings that matter in Florida are the Declaration of Domicile with your county clerk, your homestead exemption application with the county property appraiser (due March 1), and DMV/voter registration, not anything with the Florida Department of Revenue.
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.
How can I prove I actually live in Florida if I keep an apartment back home too?+
Build a file that mirrors what an auditor from your old state will ask for: a Florida homestead exemption (which itself requires proof you don't claim residency-based tax status elsewhere), driver's license and voter registration at the Florida address, a day-count log corroborated by credit card and travel records showing more time in Florida than in the old state, and utility bills showing the Florida home is actually used, not just owned.
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.
I'm a travel nurse claiming Florida as my tax home but I've barely been there this year. Is that a problem?+
Yes. Auditors have specifically disallowed Florida tax-home claims for nurses who kept a Florida address on paper while actually living full-time in an assignment-state rental and never returning. To hold up, you need to keep paying for and periodically returning to the Florida home, and hold Florida driver's license, voter registration, and vehicle registration there, not just a mailing address.
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.
How often can I go back and visit family in New York without messing up my Florida residency?+
There's no Florida-side limit; the New York side is what counts your days. If you maintain a permanent place of abode in New York (even a relative's home you can stay in) and spend more than 183 days there in a calendar year, including any part of a day, New York can tax you as a statutory resident regardless of your Florida domicile. Track every New York day, including short visits, arrival, and departure days.
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.
Does filing a Declaration of Domicile in Florida count as proof I abandoned my old state?+
It's one data point, not proof by itself. Florida's Declaration of Domicile under Fla. Stat. § 222.17 is a sworn statement recorded with the county clerk and is commonly cited in residency audits as supporting evidence, but a high-tax origin state will weigh it against where you actually spend time, where your family lives, and where your business and financial life are centered before conceding the domicile change.
