Moving from Illinois to Minnesota: Residency, Taxes, and What to Prove
Illinois's 4.95% (flat) top income tax rate becomes 9.85% in Minnesota. 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. Minnesota's statutory residency test uses a 183-day threshold.
| Factor | Illinois | Minnesota |
|---|---|---|
| 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. | Minnesota treats a person as a full-year resident if they are domiciled in Minnesota, or if both of the following apply under Minn. Stat. §290.01, subd. 7 and Minn. R. 8001.0300: the person or their spouse maintains an abode in Minnesota suitable for year-round use with its own cooking and bathing facilities, and the person spends at least 183 days of the year in Minnesota, with any part of a day counting as a full day. Unlike states that require 'more than 183 days,' Minnesota's threshold is 'at least 183,' meaning day 183 itself is enough to trigger the test. |
| 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. | Minnesota's domicile test, applied through Minn. R. 8001.0300, subp. 3 and often described by practitioners as a roughly 26-factor test, weighs where a person votes, holds a driver's license, registers vehicles, buys hunting and fishing licenses, banks, worships, belongs to clubs, and files prior returns, along with the percentage of time physically present in Minnesota outside of working hours, whether living quarters are owned or rented, and homestead property tax status. No single factor controls, and the Minnesota Supreme Court in Larson v. Commissioner of Revenue upheld the tax court's practice of weighing the full factor set against a taxpayer's stated intent rather than accepting a claimed change of domicile at face value. |
| Day Count Threshold | No fixed threshold | 183 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. | Yes. The Department of Revenue's own guidance states any part of a day physically present in Minnesota counts as a full day toward the 183-day threshold, matching how the state's audit division reconstructs day counts from financial, travel, and other third-party records. |
| 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. | Minnesota does not publish a separate month-based presumption the way New York does; the 183-day/abode test itself functions as the statutory presumption of residency independent of domicile, while domicile is assessed continuously through the multi-factor test until affirmatively changed. |

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 Minnesota Residency
| Action | Agency | Deadline |
|---|---|---|
| Obtain a Minnesota driver's license | Minnesota Department of Public Safety, Driver and Vehicle Services | within 60 days of establishing residency |
| Register any vehicle kept in Minnesota | Minnesota Driver and Vehicle Services | within 60 days of establishing residency |
| Register to vote | Minnesota Secretary of State | mail and online registration must be received 21 days before Election Day; same-day registration is available in person at the polls or during early voting |
Declaration of Domicile
Minnesota has no formal county-level declaration-of-domicile filing like Florida. Domicile is established through conduct assessed under the roughly 26-factor test in Minn. R. 8001.0300: buying or leasing a home, obtaining the Minnesota license and plates, registering to vote, switching bank and professional relationships, and shifting the actual pattern of time spent.
Homestead
Minnesota's Homestead Market Value Exclusion reduces the taxable market value of an owner-occupied primary residence by up to $30,400, and the county assessor requires the owner to be a Minnesota resident occupying the property as a primary home before granting homestead classification. Because homestead classification is itself framed as a residency-linked benefit, it is one of the specific factors the Department weighs when evaluating a contested domicile claim, in either direction.
Voter Registration
Register online, by mail (received at least 21 days before Election Day), or in person, including same-day registration at the polls or during early voting. https://mnvotes.sos.state.mn.us

New Resident Tax Traps
A new full-year Minnesota resident is taxed on worldwide income starting the date Minnesota residency begins, computed on Form M1 with Schedule M1NR handling the split year. New residents with significant investment income should also plan for Minnesota's additional 1% surtax on net investment income above $1 million, which stacks on top of the regular graduated brackets and has no equivalent in several neighboring states.
What Changes on Tax
Illinois Top Rate
4.95% (flat)
Minnesota Top Rate
9.85%
Moving from Illinois to Minnesota raises the top marginal income tax rate from about 4.95% to about 9.85%, an increase of roughly 4.9 percentage points.
Withholding Reciprocity
Illinois and Minnesota 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 Minnesota 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%.
Minnesota
Capital gains: No preferential rate. Capital gains are taxed as ordinary income at the regular graduated brackets, and gains that push net investment income above $1 million can also trigger the additional 1% surtax.
Estate or inheritance tax: Minnesota has a state estate tax with a $3 million per-person exemption that is not indexed for inflation, so more estates cross the threshold each year as asset values rise. Rates run from about 13% up to 16% on the taxable amount above the exemption. There is no separate inheritance tax.
Property tax: Minnesota's average effective property tax rate is roughly 1.0% of home value, close to the national median. The Homestead Market Value Exclusion reduces the taxable market value of an owner-occupied primary residence by up to $30,400, and the property must be classified as a homestead by the county assessor, which requires the owner to be a Minnesota resident occupying the property as their primary home.
Sales tax: State rate is 6.875%, with many cities and counties layering local option taxes on top, pushing combined rates above 8% in the Twin Cities metro.
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 Minnesota
Minnesota applies its ordinary domicile and 183-day/abode tests to a travel nurse the same as anyone else: a nurse not domiciled in Minnesota who maintains a year-round-suitable Minnesota abode and is present at least 183 days becomes a full-year resident taxed on worldwide income. The more frequent Minnesota exposure runs the other way, where a nurse claims a Florida or Texas tax home while actually living in a Minnesota rental for most of an assignment; Minnesota taxes nonresident wages for days actually worked in the state regardless of the claimed tax home.
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 Minnesota
Minnesota taxes nonresident professional athletes using the standard duty-day formula applied across nearly all income-tax states: total season compensation multiplied by the ratio of Minnesota duty days (games, practices, and mandatory team functions in the state) to total duty days for the season. This applies to visiting teams playing the Vikings, Twins, Timberwolves, and Wild in the Twin Cities.
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 Minnesota
The Minnesota snowbird pattern, retaining the family lake home or Twin Cities house while wintering in Florida or Arizona, is precisely the profile Minnesota's residency-audit program is built to examine, and Larson v. Commissioner of Revenue shows the state will pursue a contested claim for years. Keeping a year-round-suitable Minnesota abode and spending at least 183 days in the state, even across multiple visits, triggers the statutory test regardless of a claimed Florida domicile, and retained homestead classification, Minnesota hunting and fishing licenses, or continued club and church membership all count as domicile evidence under the state's roughly 26-factor rule.
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 Minnesota
Minnesota has no convenience-of-the-employer rule. A nonresident who works remotely from another state for a Minnesota-based employer is generally not taxed by Minnesota on those wages, since the state sources employee compensation to where the work is physically performed rather than to the employer's location.
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 Minnesota
Minnesota follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. A servicemember whose domicile was Minnesota before entering service remains a Minnesota domiciliary regardless of duty station unless they affirmatively establish a new domicile, while a servicemember stationed in Minnesota on orders, and a qualifying spouse, does not become a Minnesota resident solely because of the posting, and military pay is not Minnesota-source income for a nonresident servicemember stationed there.
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 Minnesota
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, protecting flight crew based at Minneapolis-St. Paul International who are domiciled outside Minnesota from full-income Minnesota taxation based solely on their duty station.
Tools for This Move
Illinois to Minnesota 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.
Is Minnesota's 183-day rule the same as other states?+
Close, but the threshold wording matters. Minnesota treats you as a resident if you spend at least 183 days in the state and maintain a year-round-suitable abode there, with any part of a day counting as a full day. That's a lower bar than states requiring 'more than 183 days,' because in Minnesota, day 183 itself is enough. Combined with a separate, ongoing domicile test, Minnesota gives itself two independent paths to keep taxing you.
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.
I claimed Florida residency years ago but Minnesota is still auditing me. Is that normal?+
For Minnesota, yes. Minnesota is regarded by practitioners as one of the most aggressive residency-audit states in the country, and it has litigated contested claims for years after the stated move date. In Larson v. Commissioner of Revenue, the Minnesota Supreme Court upheld a finding that a taxpayer remained a Minnesota domiciliary for tax years 2002 through 2006 despite claiming a 1998 move to Nevada, because the weight of the roughly 26-factor evidence still pointed to Minnesota. The state's interactive audit process is built specifically to unwind claims like this.
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.
What are the roughly 26 factors Minnesota uses to decide if I'm still domiciled here?+
Under Minn. R. 8001.0300, subp. 3, Minnesota weighs where you vote, hold your driver's license and vehicle registration, buy hunting and fishing licenses, bank, worship, and belong to clubs, along with homestead property tax status, where your kids go to school, your employer's location, and the percentage of time you're physically present in Minnesota outside working hours. No single factor decides the case; the Department and courts weigh the full pattern, and your stated intent carries less weight than what your actual conduct shows.
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.
Does keeping our family lake home in Minnesota hurt my nonresident claim?+
It can, especially combined with time spent there. A Minnesota property suitable for year-round use, including a well-equipped lake home, can count as a permanent abode for the 183-day test, and continued use and upkeep of it is also weighed under the domicile factor test. If a spouse or children still use the home regularly, that specifically works against a claim that the family has genuinely relocated.
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.
Does Minnesota tax my Social Security benefits?+
Partially, unlike many states that exempt it entirely. Minnesota provides only an income-limited subtraction for Social Security, so higher-income retirees can end up with most or all of their benefits taxed at the regular state rates. This is one of the reasons Minnesota is considered less retirement-friendly than neighboring Wisconsin or Illinois on the income-tax side.
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 Minnesota have an estate tax I need to plan around?+
Yes. Minnesota has a state estate tax with a $3 million per-person exemption that isn't indexed for inflation, and rates run from about 13% up to 16% on the taxable amount above that threshold. Because the exemption doesn't grow with inflation, more estates cross the line each year even without much real growth in wealth, which is part of why some higher-net-worth Minnesotans plan an exit well before a health event forces the issue.
