Moving from Connecticut to Indiana: Residency, Taxes, and What to Prove

Connecticut scrutinizes departures closely, so this move is as much an exit-documentation project as a tax question: the top income tax rate drops from 6.99% to 2.95% (flat, state) + county income tax.

Residency Tests Side by Side

Connecticut and Indiana both use a 183-day statutory residency threshold, so the day-count mechanics will feel familiar even though the underlying facts and enforcement differ.

FactorConnecticutIndiana
Statutory Residency TestConn. Gen. Stat. §12-701(a)(1): a person not domiciled in Connecticut is still taxed as a resident if they maintain a permanent place of abode in Connecticut and spend more than 183 days of the taxable year in the state. Connecticut's own regulations note the abode must be genuinely permanent; someone using a Connecticut apartment only during a limited work assignment, without it being a permanent place of abode, is not a statutory resident even if physically present more than 183 days.Indiana Code 6-3-1-12 and 45 IAC 3.1-1-21 define a resident two independent ways: an individual domiciled in Indiana during the tax year, or an individual who is not domiciled in Indiana but maintains a permanent place of residence in the state and spends more than 183 days of the taxable year in Indiana. Indiana guidance explicitly notes the 183-day/permanent-residence test is a separate, independent basis for residency, not itself a test for domicile.
Domicile TestDRS regulations (Conn. Agencies Regs. §12-701(a)(1)-1) direct examiners to weigh an individual's real estate, business, social, and civic connections to Connecticut, without an exhaustive checklist. In practice this mirrors New York's approach: home use, time spent, business involvement, location of family, and location of near-and-dear personal items.Under 45 IAC 3.1-1-22.5, Indiana presumes a person has not abandoned Indiana domicile if they maintained a permanent residence in Indiana and satisfy at least one of: claiming a homestead deduction or military tax exemption on an Indiana home, voting in Indiana, occupying an Indiana residence more days of the year than any other single state, claiming a federal tax benefit based on Indiana being the principal residence, or having a place of employment or business in Indiana. Supplementary factors include driver's license and vehicle registration location, dependent claims, mailing address, bank accounts, organizational memberships, and where professional services and valuables are located.
Day Count Threshold183 days183 days
Any Part of a Day RuleGenerally yes, presence in Connecticut for any part of a day counts toward the 183-day threshold, consistent with the neighboring statutory-residency states.Indiana's statute uses 'more than 183 days,' which mirrors New York's and Illinois's phrasing; Indiana guidance does not publish a specific carve-out exempting partial days, and practitioners treat any day with meaningful Indiana presence as counting toward the total absent a documented exception like medical treatment or transit.
PresumptionsNone published beyond the two-prong statutory test. Connecticut's regulations do carve out that a genuinely temporary, work-related apartment is not a 'permanent' place of abode even if occupied for a long stretch, which is a narrower exception than New York's.45 IAC 3.1-1-22.5 creates a presumption against abandonment of Indiana domicile whenever a person kept a permanent Indiana residence and meets at least one of the five primary factors listed above (homestead claim, voting, most-days-in-state, federal filing benefit, or Indiana employment); this presumption is rebuttable but places real weight on continuing to hold any one of those Indiana connections.

Leaving Connecticut

Very high exit scrutiny (4/5)

Connecticut is named alongside New York, California, New Jersey, and a small handful of other states as one of the more aggressive residency-audit jurisdictions, and DRS reportedly audits Connecticut-to-Florida movers at high rates, especially when a Connecticut home is kept. The state's revenue base is unusually concentrated among high earners in Fairfield County and similar towns, which practitioners say makes DRS particularly attentive to departures following a liquidity event such as a business sale. Daniels v. Commissioner of Revenue Services (2026) shows this scrutiny extends past income tax into estate tax domicile disputes litigated years after death.

Trailing Income

Connecticut's own convenience of the employer rule, enacted in 2019, reciprocally taxes a nonresident who works remotely for a Connecticut-based employer if that person resides in a state that imposes its own convenience rule on Connecticut residents, principally New York. Separately, Connecticut's estate tax reaches a decedent's full estate if DRS's audit division determines Connecticut was still the true domicile at death, regardless of how many years the person spent claiming residency elsewhere.

Part-Year Filing

Form CT-1040NR/PY, Connecticut Nonresident and Part-Year Resident Income Tax Return, covers both part-year residents leaving the state and nonresidents with Connecticut-source income.

Enforcement Methods

review of real estate, social, business, and civic connections per DRS domicile regulations
travel and financial records
comparison of time actually spent at each residence
cross-examination of which home functioned as the genuine center of life
post-death domicile audits triggered by estate filings

Common Exit Mistakes

Keeping the Connecticut house without selling or renting it, rather than fully converting it to a secondary or vacation property
Assuming a Florida or Arizona home is automatically the new domicile without documenting the shift in social, business, and civic ties that Connecticut regulations specifically examine
Underestimating the estate tax domicile exposure, which can be audited and litigated after death even when day counts were never close to 183
Splitting time roughly evenly among Connecticut and one or more other states without a clear preponderance of connections to any single one

Declaration of Domicile

Indiana has no county-level declaration-of-domicile filing like Florida. Domicile is established through the conduct listed in 45 IAC 3.1-1-22.5: buying or leasing a home, registering to vote, obtaining the Indiana license and plates, claiming the homestead deduction, and shifting where employment and business activity actually occur.

Homestead

The Homestead Standard Deduction reduces assessed value by the lesser of $48,000 or 60% of assessed value on an owner-occupied principal residence, with an additional supplemental deduction on the remaining assessed value. Because Indiana law specifically directs the Department of Local Government Finance and county auditors to develop procedures to catch homestead claimants whose actual principal residence is outside Indiana, claiming or removing this deduction is a real, checkable data point for anyone establishing or leaving Indiana domicile.

New Resident Tax Traps

A new full-year Indiana resident is taxed on worldwide income from the date Indiana residency begins, reported on Form IT-40PNR for the split year, which also requires sorting out the county income tax based on county of residence. New residents should identify their county's local tax rate promptly, since it stacks on top of the 2.95% state rate and varies substantially, from roughly 0.5% in some counties to over 3% in others.

What Changes on Tax

Connecticut Top Rate

6.99%

Indiana Top Rate

2.95% (flat, state) + county income tax

Moving from Connecticut to Indiana drops the top marginal income tax rate from about 6.99% to about 2.95%, a reduction of roughly 4.04 percentage points.

Withholding Reciprocity

Connecticut and Indiana 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

Connecticut and Indiana both use common law, equitable-distribution marital property rules, so no community property transition applies to this move.

Beyond Income Tax

Connecticut

Capital gains: No preferential rate. Capital gains are taxed as ordinary income at the same graduated brackets as wages.

Estate or inheritance tax: Connecticut has both an estate tax and, uniquely among the states, its own gift tax. The 2026 exemption is aligned with the federal basic exclusion amount (roughly $13.99 million), taxed at a flat 12% above that threshold, with total Connecticut estate tax liability capped at $15 million per estate. There is no separate inheritance tax.

Property tax: Effective rates average roughly 1.8% to 1.9% statewide, among the higher burdens in New England, though it varies sharply by town, lower in parts of Fairfield County relative to home values, considerably higher in older industrial cities.

Sales tax: Flat 6.35% statewide rate with no local add-on, one of the simpler sales tax structures in the Northeast.

Indiana

Capital gains: No preferential rate. Capital gains are taxed as ordinary income at the flat state rate plus the applicable county rate.

Estate or inheritance tax: Indiana has no state estate tax and no inheritance tax; Indiana repealed its inheritance tax effective 2013. Only the federal estate tax, with its roughly $15 million per-person exemption in 2026, can apply to an Indiana decedent's estate.

Property tax: Indiana's average effective property tax rate is around 0.8% of home value, among the lower rates in the Midwest. The Homestead Standard Deduction reduces assessed value by the lesser of $48,000 or 60% of assessed value for an owner-occupied principal residence, with an additional supplemental deduction on the remaining value; county auditors are directed to develop procedures specifically to catch owners whose actual principal residence is outside Indiana.

Sales tax: Indiana has a flat statewide 7% sales tax, sometimes called the Gross Retail Tax, with no additional local sales tax layered on top anywhere in the state.

Who This Move Applies To

Travel Nurses

In Connecticut

The same statutory residency test applies to a travel nurse on a Connecticut hospital assignment as to anyone else: keeping a genuinely permanent Connecticut abode while accumulating more than 183 days in the state triggers statutory residency and worldwide-income taxation. Connecticut's regulatory carve-out for a non-permanent, work-related apartment gives traveling healthcare workers on shorter rotations a somewhat clearer defense than in states without that language, provided the housing is documented as temporary.

In Indiana

Indiana applies its ordinary domicile and 183-day/permanent-residence tests to a travel nurse the same as anyone else: a nurse not domiciled in Indiana who keeps a permanent Indiana residence and is present more than 183 days becomes an Indiana resident on worldwide income for that year, plus the applicable county tax. The more frequent exposure runs the other way, where a nurse claims a Florida or Texas tax home while actually renting in Indiana for most of an assignment; Indiana taxes nonresident wages for days actually worked in the state regardless of the claimed tax home.

Professional Athletes

In Connecticut

Connecticut has no major men's professional sports franchise based in the state, but it does tax nonresident athletes and entertainers on Connecticut-source income using duty-day apportionment. This reaches visiting performers and athletes at venues like Mohegan Sun and Foxwoods, and the home roster of the WNBA's Connecticut Sun, which plays at Mohegan Sun Arena.

In Indiana

Indiana 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 Indiana duty days (games, practices, and mandatory team functions in the state) to total duty days for the season. This applies to visiting NFL and NBA teams playing the Colts and Pacers in Indianapolis, and Indiana's flat, comparatively low rate means the dollar amount at stake per game is smaller than in higher-rate states, though the filing obligation is the same.

Snowbirds, Long Visitors, and RVers

In Connecticut

Daniels v. Commissioner of Revenue Services is the clearest illustration of Connecticut's posture toward long-time snowbirds: a decedent who divided his time among Connecticut, Arizona, and Florida had his estate audited after death, and even though a Superior Court found his Connecticut and Florida ties 'generally equal,' the taxpayer's estate still lost under the higher clear-and-convincing evidence standard then in use. The Connecticut Supreme Court's June 2026 ruling lowered that standard to a preponderance of the evidence and sent the case back for retrial, which helps future snowbird estates but confirms Connecticut will litigate close domicile calls rather than concede them.

In Indiana

The Indiana snowbird risk runs through the same domicile-abandonment presumption that protects year-round Indiana residents: a retiree who keeps a permanent Indiana residence, continues to vote in Indiana, or keeps the homestead deduction active while wintering in Florida is presumed not to have abandoned Indiana domicile. Separately, spending more than 183 days in Indiana in a year while maintaining a permanent Indiana residence independently triggers Indiana residency regardless of domicile intent.

Remote Workers

In Connecticut

Connecticut enacted its own reciprocal convenience of the employer rule in 2019: a nonresident who works remotely for a Connecticut employer is taxed as if working in Connecticut if their home state, principally New York, imposes its own convenience rule on Connecticut residents. The most visible current dispute runs the other direction, a Connecticut resident, Cardozo Law School professor Edward Zelinsky, has spent years challenging New York's convenience rule for taxing the income he earns teleworking from his Connecticut home for a New York City law school; the New York Tax Appeals Tribunal upheld the rule against him again in May 2025, with further appeal pending.

In Indiana

Indiana has no convenience-of-the-employer rule. A nonresident who works remotely from another state for an Indiana-based employer is generally not taxed by Indiana on those wages, since Indiana sources employee compensation to where the work is physically performed rather than to the employer's location.

Military

In Connecticut

Connecticut follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act: a servicemember or accompanying spouse domiciled elsewhere who is in Connecticut solely on military orders is not treated as a Connecticut domiciliary, and military pay is not taxed by Connecticut for a nonresident servicemember stationed there.

In Indiana

Indiana follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. A servicemember whose domicile was Indiana before entering service remains an Indiana domiciliary regardless of duty station unless they affirmatively establish a new domicile, while a servicemember stationed in Indiana on orders, and a qualifying spouse, does not become an Indiana resident solely because of the posting; Indiana also allows a deduction for certain military retirement income.

Airline Crew

In Connecticut

Federal law (49 U.S.C. §40116) limits states to taxing air carrier employee compensation only in the employee's state of residence and any state where more than 50% of pay is earned. This is relevant to crew connected to Bradley International Airport, a smaller hub than New York's or New Jersey's, who are domiciled outside Connecticut.

In Indiana

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 Indianapolis International who are domiciled outside Indiana from full-income Indiana taxation based solely on their duty station.

Connecticut to Indiana FAQ

I split time between Connecticut, Florida, and Arizona and never fully closed any of the homes. How does Connecticut decide which one is my domicile?+

DRS regulations direct examiners to weigh your real estate, business, social, and civic connections to Connecticut against those in your other states, without a strict day-count shortcut. Daniels v. Commissioner of Revenue Services involved exactly this fact pattern, and a Superior Court initially found the Connecticut and Florida ties roughly equal, which meant the outcome turned on which side had the burden of proof and how high that bar was set, not on a single deciding factor.

Does Indiana have a 183-day rule separate from domicile?+

Yes, and Indiana is explicit that the two are independent tests. Under IC 6-3-1-12 and 45 IAC 3.1-1-21, you're an Indiana resident if you're domiciled in Indiana, or separately, if you're not domiciled in Indiana but maintain a permanent Indiana residence and spend more than 183 days in the state during the year. Indiana's own guidance says the 183-day test is not itself a test for domicile, so you can fail one and still be caught by the other.

Does Connecticut have a day-count safe harbor like New York's 548-day rule for people working abroad?+

No published Connecticut safe harbor of that kind exists. Connecticut's statutory residency test is the same 183-day-plus-permanent-abode formula used elsewhere, but the state has not enacted a separate carve-out for domiciliaries working outside the country the way New York has with its 548-day rule. Anyone relying on extended foreign work to avoid Connecticut residency should plan around the general domicile and 183-day tests rather than assume an equivalent safe harbor exists.

If I move to Florida but keep voting absentee or in person in Indiana, does that hurt my case?+

Yes, directly. Indiana's domicile-abandonment rule under 45 IAC 3.1-1-22.5 presumes you haven't given up Indiana domicile if you keep a permanent Indiana residence and continue voting in Indiana, among other listed factors. Re-registering to vote in your new state, and actually voting there, is one of the more concrete steps that supports a genuine domicile change.

My late father kept homes in Connecticut and Florida his whole retirement. Can Connecticut still claim him as domiciled after death?+

Yes, and this is precisely what happened in Daniels v. Commissioner of Revenue Services. DRS audited the estate, found Connecticut domicile despite the decedent's time split among Connecticut, Arizona, and Florida, and the fight over which state got to tax the estate continued for years after death. The 2026 Connecticut Supreme Court decision made it somewhat easier for an estate to win this kind of dispute by lowering the burden of proof, but it confirms Connecticut treats a genuinely divided retirement lifestyle as a real audit target, not a hypothetical one.

Will keeping the homestead deduction on my Indiana house hurt me if I claim I moved to Florida?+

Yes. Indiana law specifically directs the Department of Local Government Finance and county auditors to develop procedures to identify homestead deduction claimants whose actual principal residence is outside Indiana, so continuing to claim it while filing as a nonresident elsewhere is exactly the kind of contradiction those procedures are built to catch. If you've genuinely moved, notifying your county auditor to remove the deduction is one of the concrete steps supporting your new domicile.

I'm a Connecticut resident working from home for a New York employer. Does New York's convenience rule really reach me?+

Yes, and Connecticut residents are the test case for this exact question. Cardozo Law School professor Edward Zelinsky, a Connecticut resident who teleworks for a New York City employer, has litigated New York's convenience of the employer rule for years; the New York Tax Appeals Tribunal upheld the rule against him again in May 2025. Unless your remote work meets New York's narrow necessity exception, New York can tax your full salary as if you worked in its office every day, even though you never leave Connecticut.

How does Indiana's county income tax work if I move counties or move out of state mid-year?+

On top of the flat 2.95% state rate, every Indiana county levies its own income tax, ranging roughly from 0.5% to over 3%, and your county rate generally depends on your county of residence. When you move into or out of Indiana mid-year, Form IT-40PNR handles both the state and county allocation for the split year, which makes Indiana's exit-year filing meaningfully more involved than a state with a single flat rate and no local layer.

Does Connecticut have its own convenience of the employer rule for remote workers?+

Yes, since 2019. Connecticut taxes a nonresident who works remotely for a Connecticut-based employer as if they worked in Connecticut, but only if that nonresident's home state also imposes its own convenience rule on Connecticut residents, which today means New York. If you work remotely for a Connecticut employer from a state without a convenience rule, Connecticut generally does not apply this rule to you.

I live in Kentucky and work in Indiana. Do I owe Indiana income tax on my wages?+

No, not on wages. Indiana has reciprocity agreements with Kentucky, Michigan, Ohio, Pennsylvania, and Wisconsin, so a Kentucky resident's wages earned working in Indiana are taxed only by Kentucky, not Indiana, and Indiana withholding should not apply. Reciprocity covers wage income only; investment, rental, and business income from Indiana sources are still taxable by Indiana.

If I keep a small apartment in Connecticut just for occasional work trips, does that alone make me a statutory resident?+

Not by itself. Connecticut's own regulations distinguish a genuinely temporary, work-related apartment from a permanent place of abode, and an apartment used only for limited work purposes, even for a stretch exceeding 183 days of physical presence, has been treated as falling outside the statutory residency test because it isn't permanent. The distinction depends heavily on the facts, including lease length, how the space is furnished and used, and whether it functions as anything close to a real home.

Does Indiana tax my Social Security or pension after I retire?+

Social Security is fully exempt from both Indiana state and county tax. Pension, 401(k), and IRA distributions are taxed as ordinary income at the flat state rate plus your county's local rate, since Indiana doesn't offer the kind of broad age-based retirement income exclusion that Illinois or Michigan provide, aside from a modest deduction for certain military and railroad retirement income.

Connecticut to Indiana Reading

What a State Residency Audit Actually Asks For, Month by MonthA residency audit does not arrive as one giant document demand. It arrives as a sequence, and every state runs roughly the same one: a short questionnaire, then a document request, then a rebuilt day count from other people’s records, then a request to extend the statute of limitations, then a position letter and a countdown measured in days. Here is that sequence in New York, California, and Connecticut, taken from the agencies’ own audit manuals.The Case That Turned on Where a Man Kept His DogNew York asserted $430,065 against a CEO who moved to Dallas. He kept his Manhattan apartment, kept a boat in the Hamptons, and won anyway, because he moved his elderly rescue dog. Here is what the near and dear factor actually is, the mirror-image case where a taxpayer lost with a Michigan license in his pocket, and why neither case was decided by a day count.What Does It Cost to Defend a Residency Audit?No state publishes what it costs to fight a residency audit. Working from practitioner fee schedules, published audit statistics, and our own 56-jurisdiction research, here is what the defense bill actually looks like and what drives it.The Travel Journal Method, and Why It Fails Under AuditKeep a travel journal is the advice everyone gives someone changing states. New York’s own audit manual accepts a diary as proof, and then explains how auditors will test it. Here is what happened in the cases where a journal failed, what saved the ones that worked, and how states figure out you moved long before anyone asks to see your calendar.
