Moving from Pennsylvania to Illinois: Residency, Taxes, and What to Prove
Pennsylvania's 3.07% top income tax rate becomes 4.95% (flat) in Illinois. This move trades a lighter tax environment for a heavier one, so timing income around the transition year matters.
Residency Tests Side by Side
Pennsylvania's statutory residency test uses a 183-day threshold. Illinois does not use a simple day-count threshold; it applies a facts-and-circumstances test instead.
| Factor | Pennsylvania | Illinois |
|---|---|---|
| Statutory Residency Test | A person domiciled outside Pennsylvania becomes a Pennsylvania statutory resident, taxed the same as a domiciliary, if they maintain a permanent place of abode in Pennsylvania and spend more than 183 days in the state during the tax year. This runs independently of, and in addition to, the domicile 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. |
| Domicile Test | Pennsylvania residents are taxed on all income, Pennsylvania-source and otherwise, based on domicile: the place a person regards as home and intends to return to. The Department of Revenue's guidance lists the practical factors it weighs, where the person spends most of their time, where they maintain bank accounts, where they own real estate, where they hold professional licenses, where they vote, and where they hold a driver's license and register vehicles, the same multi-factor evidentiary approach used in New York and other statutory-resident states. | 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. |
| Day Count Threshold | 183 days | No fixed threshold |
| Any Part of a Day Rule | Not explicitly detailed as any-part-of-a-day in the Department's published guidance reviewed for this research; the statutory test is framed as spending more than 183 days in Pennsylvania while maintaining a permanent place of abode, so the safe planning assumption is that any day of Pennsylvania presence, however brief, counts toward the total. | 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. |
| Presumptions | None published | 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. |
| Safe Harbors | Non-permanent abode carve-out | None published |
Leaving Pennsylvania
Philadelphia's collar counties (Montgomery, Bucks, Chester, Delaware) and the Pittsburgh suburbs are the areas practitioners most associate with Pennsylvania domicile disputes, typically retirees or high earners who move to Florida or another no-income-tax state but keep a Pennsylvania home, spend significant time there, and maintain local professional or business ties. Pennsylvania is not consistently named alongside New York, California, New Jersey, Connecticut, Maryland, and Minnesota as one of the most aggressive dedicated exit-audit states in the practitioner and community sources reviewed for this research, but the statutory-resident 183-day-plus-abode test gives the Department a straightforward mechanism to challenge a departure if the taxpayer keeps a maintainable Pennsylvania residence and spends too much time in it.
Trailing Income
Pennsylvania taxes Pennsylvania-source income earned by a nonresident after departure under its standard sourcing framework, wages for work performed in Pennsylvania, income from a Pennsylvania business, and Pennsylvania real property income; no Pennsylvania-specific deferred-compensation clawback statute distinct from ordinary multistate sourcing was located in this research pass. Separately, local EIT obligations can continue to apply based on where work is actually performed even after a person's state domicile has changed.
Part-Year Filing
Part-year residents file Form PA-40, the same form used by full-year residents and nonresidents, using the residency status and apportionment schedules to report worldwide income for the Pennsylvania-resident portion of the year and only Pennsylvania-source income for the nonresident portion.
Enforcement Methods
Common Exit Mistakes
Establishing Illinois Residency
| Action | Agency | Deadline |
|---|---|---|
| Obtain an Illinois driver's license | Illinois Secretary of State | within 90 days of establishing residency (out-of-state license valid until then) |
| Register any vehicle kept in Illinois, with Illinois insurance in place first | Illinois Secretary of State, Vehicle Services | within 30 days of establishing residency |
| Register to vote | Illinois State Board of Elections | online and mail registration closes 16 days before an election; grace-period in-person registration and voting runs from 27 days before Election Day through Election Day |
Declaration of Domicile
Illinois has no formal declaration-of-domicile filing comparable to Florida's county-level process. Domicile is established through conduct alone: buying or leasing a home, getting the Illinois license and plates, registering to vote, and shifting the pattern of where professional, banking, and family life actually happens.
Homestead
The General Homestead Exemption reduces the equalized assessed value of an owner-occupied principal residence by up to $10,000 in Cook County, $8,000 in the counties bordering Cook, and $6,000 elsewhere, and requires ownership and occupancy as of January 1 of the tax year. It functions as useful domicile evidence for someone establishing Illinois residency, since applying for it requires attesting the home is a principal residence, and county assessors can cross-check driver's license and voter registration addresses against the exemption claim.
Voter Registration
Register online through the Illinois Online Voter Registration Application, by mail, or in person; online and mail registration closes 16 days before an election, with grace-period registration and same-day voting available from 27 days before Election Day through Election Day itself. https://ova.elections.il.gov
Vehicle Registration Deadline
30 days
New Resident Tax Traps
A new full-year Illinois resident is taxed on worldwide income from the date Illinois residency begins, computed on Form IL-1040 with Schedule NR handling the split year. Because Illinois has no capital gains preference, a large gain realized right after establishing residency (stock sale, business sale, Roth conversion) is taxed at the full 4.95% flat rate with no bracket cushion the way some other states offer at lower income levels.
What Changes on Tax
Pennsylvania Top Rate
3.07%
Illinois Top Rate
4.95% (flat)
Moving from Pennsylvania to Illinois raises the top marginal income tax rate from about 3.07% to about 4.95%, an increase of roughly 1.88 percentage points.
Withholding Reciprocity
Pennsylvania and Illinois 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
Pennsylvania and Illinois both use common law, equitable-distribution marital property rules, so no community property transition applies to this move.
Beyond Income Tax
Pennsylvania
Capital gains: Capital gains are one of Pennsylvania's eight enumerated income classes and are taxed at the same flat 3.07% rate as wages; there is no separate lower rate or holding-period distinction the way the federal system has.
Estate or inheritance tax: Pennsylvania has no estate tax but does impose an inheritance tax on the transfer of a decedent's property, based on the beneficiary's relationship to the decedent: 0% to a surviving spouse or to a parent inheriting from a child 21 or younger, 4.5% to direct descendants and other lineal heirs, 12% to siblings, and 15% to all other heirs. The tax is due at death and becomes delinquent nine months later, with a 5% discount for payment within three months.
Property tax: Effective property tax rate on owner-occupied housing runs about 1.26%, on the higher side nationally, reflecting Pennsylvania's heavy reliance on local property taxes to fund school districts. Homeowners can apply for the statewide Homestead/Farmstead Exclusion under Act 1 of 2006, which reduces school property tax using gaming revenue, and Philadelphia separately runs its own Homestead Exemption reducing the taxable assessed value of an owner-occupied primary residence; this research pass could not confirm the current dollar amount of Philadelphia's exemption from a primary city source.
Sales tax: 6% state sales tax rate, with Philadelphia and Allegheny County adding local surcharges that push the average combined state-and-local rate to about 6.34%.
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%.
Who This Move Applies To
Travel Nurses
In Pennsylvania
Philadelphia and Pittsburgh's major hospital systems are large travel-nursing markets, and a nurse working Pennsylvania contracts needs to watch the statutory residency test: crossing 183 days of Pennsylvania presence while maintaining anything that qualifies as a permanent (not purely temporary) place of abode, an apartment lease rather than short-term corporate housing, for example, can pull the nurse into Pennsylvania statutory residency regardless of a claimed 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.
Professional Athletes
In Pennsylvania
Philadelphia is home to the Eagles (NFL), Phillies (MLB), 76ers (NBA), and Flyers (NHL), making it one of the country's most active jock-tax markets; visiting players owe Pennsylvania nonresident tax apportioned by duty days spent in the state for games, practices, and team activities under the standard multistate duty-day framework, while Pennsylvania-based players are taxed on their full income at the flat 3.07% state rate plus any applicable Philadelphia wage tax, 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.
Snowbirds, Long Visitors, and RVers
In Pennsylvania
A Pennsylvania domiciliary who winters in Florida or another warm-weather state but keeps the Pennsylvania home in maintainable condition and returns for more than half the year remains a Pennsylvania resident on domicile grounds alone; the more contested scenario is the reverse, someone who has genuinely moved their domicile out of Pennsylvania but keeps a Pennsylvania house available and visits often enough to cross 183 days, which can trigger Pennsylvania statutory residency even after a real domicile change, unless the retained property qualifies as non-permanent lodging (which a fully maintained house generally does not).
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.
Remote Workers
In Pennsylvania
Pennsylvania has no convenience-of-the-employer rule of its own; a remote worker physically performing work from Pennsylvania for an out-of-state employer generally owes Pennsylvania tax on that Pennsylvania-source income based on physical presence, and does not separately owe the employer's home state tax on those same wages unless that state applies its own convenience rule, which is the scenario Pennsylvania arrivals from convenience-rule states like New York need to watch in their employer's withholding treatment. Pennsylvania also has long-documented reciprocal wage-tax agreements with several neighboring states (commonly cited as Indiana, Maryland, New Jersey, Ohio, Virginia, and West Virginia), under which a resident of one state working in the other pays tax only to their state of residence rather than both; this research pass could not obtain a fresh confirmation directly from the Department of Revenue's site this session, so verify current reciprocal-state status before relying on it for a specific filing.
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.
Military
In Pennsylvania
Pennsylvania follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act: a servicemember stationed in Pennsylvania on orders does not become a Pennsylvania domiciliary solely because of the posting, and an MSRRA-eligible spouse can generally retain the servicemember's state of legal residence for tax purposes.
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.
Airline Crew
In Pennsylvania
Philadelphia International Airport is a major American Airlines hub with a substantial resident 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 more than 50% of pay is earned, so Pennsylvania-domiciled crew are taxed on their full wages at the flat 3.07% rate regardless of how 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.
Tools for This Move
Pennsylvania to Illinois FAQ
I moved out of Pennsylvania but still own my old house and visit a lot. Am I still a Pennsylvania resident?+
You could be, even with a genuine domicile change, if you spend more than 183 days a year in Pennsylvania and the property qualifies as a permanent place of abode, meaning it can be maintained as a household indefinitely, not a dorm room or short-term corporate housing. That combination triggers Pennsylvania's statutory residency test independent of your stated domicile, so if you're keeping the house in livable condition, watch your day count closely.
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.
Does Pennsylvania tax my Social Security or pension?+
No. Social Security is fully exempt, and pension income is fully exempt once you've reached the plan's retirement age, generally treated as 59 1/2 or older for most retirees. 401(k) and IRA distributions are also fully exempt at that point, which makes Pennsylvania one of the more retiree-friendly states on income tax specifically, even though its property and inheritance taxes are less generous.
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.
What is this local Earned Income Tax I keep seeing, separate from the state tax?+
Pennsylvania layers a local Earned Income Tax on top of the flat 3.07% state rate, collected through county Tax Collection Districts under Act 32. Your municipality and school district both levy a share, at rates that vary by location, and your employer withholds it based on where you live and work. It's a real, separate bill, not a replacement for the state tax, and new residents often underbudget for it.
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 Pennsylvania have an estate tax?+
No estate tax, but Pennsylvania does have an inheritance tax based on your relationship to the deceased: 0% for a surviving spouse, 4.5% for children and other direct descendants, 12% for siblings, and 15% for everyone else. It's due within nine months of death, with a 5% discount if paid within the first three months.
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.
What form do I file for the year I move to or from Pennsylvania?+
Form PA-40, the same return used by full-year residents and nonresidents, marked with your part-year residency status and using the state's apportionment schedules to allocate income between the resident and nonresident portions of the year.
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.
I'm a travel nurse on back-to-back Pennsylvania contracts. Could I become a Pennsylvania resident by accident?+
Yes, if you cross 183 days of Pennsylvania presence in a tax year and your housing there qualifies as a permanent place of abode, meaning an apartment lease rather than short-term corporate or hospital-provided housing, you can be classified as a statutory resident regardless of your claimed tax home in another state. Track your Pennsylvania day count across consecutive contracts, and pay attention to what kind of housing you're in.
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.
