Moving from Delaware to Kansas: Residency, Taxes, and What to Prove
The top income tax rate drops from 6.6% in Delaware to 5.58% in Kansas. Establishing Kansas residency correctly is what protects that benefit.
Residency Tests Side by Side
Delaware's statutory residency test uses a 183-day threshold. Kansas does not use a simple day-count threshold; it applies a facts-and-circumstances test instead.
| Factor | Delaware | Kansas |
|---|---|---|
| Statutory Residency Test | Under 30 Del. C. § 1103, an individual who maintains a place of abode in Delaware and spends in the aggregate more than 183 days of the taxable year in Delaware is a resident for that portion of the year, independent of domicile. This mirrors the classic New York-style 183-day-plus-abode formulation used across much of the Northeast and mid-Atlantic. | Kansas does not run a separate day-count statutory residency test layered on top of domicile the way New York or California do. Kansas Department of Revenue guidance defines a Kansas resident for income tax purposes as anyone who lives in Kansas, regardless of where they are employed, and an individual who is away from Kansas for a period of time but intends to return remains a Kansas resident the entire time they are away. K.S.A. 79-32,109 supplies the underlying statutory definition of resident individual that KDOR guidance implements. |
| Domicile Test | Delaware treats an individual domiciled in Delaware as a resident for the period of that domicile under 30 Del. C. § 1103. Domicile itself follows the common-law standard cited in Delaware practitioner guidance: the place a person intends as their permanent home and to which they intend to return, with a person able to hold only one domicile at a time; Delaware's statute does not publish an extensive itemized factor list the way Maine or New York do, so practitioners apply the general totality-of-circumstances domicile factors (home ownership, employment, family location, licensing, and consistent documentation across financial and civic records). | Kansas weighs the usual facts-and-circumstances domicile factors under Kansas Administrative Regulation 92-12-4: where the taxpayer's permanent home is, where they are registered to vote, where their driver's license and vehicle registration are held, where they claim the Kansas Homestead Refund, and the location of family, employment, and financial accounts. No single factor is dispositive; KDOR and the Board of Tax Appeals weigh the whole pattern of conduct. |
| Day Count Threshold | 183 days | No fixed threshold |
| Any Part of a Day Rule | Not independently confirmed in the statutory text reviewed for this dossier; consult 30 Del. C. § 1103 and Division of Revenue guidance directly, but treat any Delaware presence conservatively as a full day for planning purposes, consistent with the norm in comparable 183-day-plus-abode states. | Not applicable. Kansas has no statutory day-count test, so there is no rule treating a single hour of physical presence as a full day the way California and New York do for their own statutory residency tests. A Kansas domicile dispute turns on intent and conduct, not a day tally. |
| Presumptions | None published | None published |
| Safe Harbors | Foreign residence exception to domicile-based residency | None published |
Leaving Delaware
Delaware does not carry the national reputation for aggressive residency-exit enforcement that New York, California, New Jersey, or Connecticut do, and it does not appear on the standard practitioner lists of the most audit-active states. The bigger Delaware-specific exposure runs in the opposite direction of a typical exit story: Delaware's convenience-of-the-employer rule can keep taxing former residents (and even people who never lived in Delaware) on wages from a Delaware-based employer if they work remotely by their own choice rather than the employer's requirement.
Trailing Income
Delaware's convenience-of-the-employer rule is the state's most consequential trailing-income mechanic: if an employee of a Delaware-based company works from home in another state for their own convenience rather than because the employer requires it, Delaware treats that income as Delaware-source and taxable, even after the employee has genuinely moved away and even if they never again set foot in Delaware. This can create double taxation, offset only by whatever credit the new home state allows for tax paid to Delaware.
Part-Year Filing
Part-year residents file Form 200-02, the Delaware Individual Non-Resident Income Tax Return, which is also used to apportion income for a part-year filer between the resident and nonresident portions of the year.
Enforcement Methods
Common Exit Mistakes
Establishing Kansas Residency
| Action | Agency | Deadline |
|---|---|---|
| Obtain a Kansas driver's license | Kansas Division of Vehicles (DOV) | within 90 days of establishing residency |
| Title and register vehicles in Kansas | Kansas Division of Vehicles (DOV) / county treasurer | within 90 days of establishing residency |
| Register to vote | Kansas Secretary of State | at least 21 days before an election |
| File a Homestead Refund claim if income-eligible | Kansas Department of Revenue | with the annual K-40H, generally by April 15 |
Declaration of Domicile
Kansas has no formal declaration-of-domicile filing comparable to Florida's county-recorded declaration. Kansas domicile is established purely through conduct: home purchase or lease, driver's license, vehicle registration, voter registration, and the general pattern of where a person actually lives and intends to remain.
Homestead
Kansas's Homestead Refund is an income-capped property tax rebate, not a value-reducing exemption, filed annually on Form K-40H. It requires Kansas residency for the entire claim year and household income under a set threshold, layered with age (55+), disability, or dependent-child qualifications. A separate 75% property tax refund (Form K-40PT) exists for homeowners 65 and older with lower household income. Because both programs require full-year Kansas residency, a Homestead Refund claim is one of the clearest pieces of domicile evidence, and also one of the clearest contradictions if claimed after a move.
Voter Registration

New Resident Tax Traps
Kansas taxes worldwide income from the date Kansas residency begins, reported on the full-year Form K-40 for a full calendar year of residency or Schedule S Part B for a part-year. New residents moving from a no-tax state like Texas or a nearby low-tax state sometimes underestimate the combined burden of Kansas's income tax plus its comparatively high combined sales tax (8.69% average), which is not offset by any local income tax the way some states' totals are.
What Changes on Tax
Delaware Top Rate
6.6%
Kansas Top Rate
5.58%
Moving from Delaware to Kansas drops the top marginal income tax rate from about 6.6% to about 5.58%, a reduction of roughly 1.02 percentage points.
Withholding Reciprocity
Delaware and Kansas 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
Delaware and Kansas both use common law, equitable-distribution marital property rules, so no community property transition applies to this move.
Beyond Income Tax
Delaware
Capital gains: Taxed as ordinary income with no separate Delaware capital gains rate or broad exclusion; a capital gain is added to Delaware taxable income and taxed at the same graduated rates as wages, up to 6.6%.
Estate or inheritance tax: None. Delaware repealed its estate tax effective January 1, 2018, and has no separate inheritance tax, making it one of the more estate-tax-friendly mid-Atlantic states alongside its long-standing reputation for trust-friendly law through the Delaware Court of Chancery.
Property tax: Delaware has one of the lowest average effective property tax rates in the country, commonly cited around 0.50% to 0.54% of home value, the product of county assessments in New Castle, Kent, and Sussex counties that have gone many years between full reassessments.
Sales tax: None. Delaware has no state or local sales tax at all, a signature draw for the Wilmington-area shopping corridor that pulls consumers from Pennsylvania, New Jersey, and Maryland.
Kansas
Capital gains: Kansas has no separate capital gains rate. Gains flow through federal adjusted gross income into Kansas adjusted gross income and are taxed at the same 5.2%/5.58% rates as ordinary income.
Estate or inheritance tax: None. Kansas repealed its inheritance tax decades ago and has no separate estate tax; only the federal estate tax, with its much higher exemption, can reach a Kansas decedent's estate.
Property tax: Effective property tax rate on owner-occupied housing runs about 1.21%. Kansas does not use a Florida-style homestead exemption that reduces taxable value; instead it runs the Homestead Refund program (Form K-40H), an income-capped property tax rebate of up to $700 for qualifying homeowners who are 55 or older, blind or disabled, or have a dependent child under 18, and a separate 75% property tax refund (Form K-40PT) for homeowners 65 and older with lower household income.
Sales tax: State rate is 6.5%, with a statewide average combined rate (state plus local) of about 8.69%, one of the higher combined averages in the country because Kansas allows extensive city and county sales tax stacking.
Who This Move Applies To
Travel Nurses
In Delaware
Delaware has no nurse-specific tax-home guidance; the general IRS tax-home rules under Publication 463 govern whether stipends stay tax-free, and Delaware's own residency status for a nurse turns on the same 183-day-plus-abode or domicile tests everyone else faces under 30 Del. C. § 1103.
In Kansas
Kansas has no statutory carve-out for travel nurses distinct from its general domicile test; a nurse's Kansas tax home question is resolved under IRS Publication 463's tax-home concept for federal stipend treatment, and Kansas residency then follows the same domicile-and-intent analysis as any other taxpayer. Kansas hospital systems in Wichita, Topeka, and the Kansas City metro draw a steady stream of travel nursing assignments, and a nurse who claims a tax home outside Kansas while spending most of the year in a Kansas rental apartment faces the same tax-home disallowance risk documented nationally on travel-nurse forums.
Professional Athletes
In Delaware
Delaware has no major professional sports franchises, so it runs no state-specific jock-tax apportionment regime. A Delaware-domiciled athlete owes Delaware tax on worldwide income (with credits for tax paid to other states on away-game duty days) but faces no in-state team creating reciprocal audit interest from opposing states.
In Kansas
Kansas is home to the Kansas Speedway and hosts Chiefs training-camp-adjacent business activity given the team's Kansas City, Missouri stadium sits just across the state line, but Kansas itself has no major-league franchise based in-state. Visiting athletes who play games in Kansas (at Kansas Speedway events or exhibition games) are subject to Kansas's duty-day apportionment framework for nonresident athlete income, consistent with how most states with an income tax administer the jock tax.
Snowbirds, Long Visitors, and RVers
In Delaware
Delaware's beach communities (Rehoboth, Bethany, Lewes) draw significant seasonal second-home ownership from Pennsylvania, Maryland, and Washington D.C. Anyone who keeps a Delaware beach house and crosses 183 aggregate days of Delaware presence in a year, while maintaining that home as a place of abode, becomes a Delaware statutory resident regardless of where they claim domicile, the same mechanic that applies in New York or Vermont.
In Kansas
Because Kansas has no day-count statutory residency test, a Kansas snowbird who winters in Arizona or Florida does not face a bright-line trigger the way a New York or California resident would; the question is simply whether the Kansas home remains the taxpayer's true domicile, judged on the same conduct factors (driver's license, voter registration, Homestead Refund claims) as any other Kansas residency question. The bigger snowbird risk runs the other direction: a Kansas Homestead Refund claim requires full-year Kansas residency, so a homeowner who spends a large part of the year in a warm-weather state should not claim it if they can't support full-year Kansas residency.
Remote Workers
In Delaware
This is Delaware's most distinctive special-situation fact: Delaware applies a convenience-of-the-employer rule, treating work done from home by an employee of a Delaware-based company as Delaware-source income whenever the remote arrangement is for the employee's own convenience rather than a genuine employer requirement. Combined with no reciprocity agreements with any neighboring state, this leaves remote workers for Delaware employers in Pennsylvania, New Jersey, or Maryland at real risk of double taxation unless their home state grants a full credit for the Delaware tax.
In Kansas
Kansas has no published convenience-of-the-employer rule, so a genuine Kansas resident working remotely for an out-of-state employer is taxed by Kansas as a resident regardless of the employer's location, and a nonresident working remotely for a Kansas employer generally is not pulled into Kansas tax solely because the employer is headquartered there. The recurring Kansas-specific version of this issue is Kansas City metro commuters: someone who lives on the Kansas side and works, even partly remotely, for a Missouri-based employer (or vice versa) has to track actual work-location days carefully, since neither state applies a convenience rule to override where the work was physically performed.
Military
In Delaware
Delaware follows the federal SCRA and MSRRA framework: a service member's home-of-record does not change solely because military orders station them in Delaware, and an accompanying spouse can generally elect the service member's domicile state under MSRRA for tax purposes.
In Kansas
Kansas follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. A servicemember whose home of record is Kansas remains a Kansas domiciliary and taxpayer regardless of duty station, and Kansas does not tax the military pay of a nonresident servicemember stationed in Kansas solely because of orders. Fort Riley and McConnell Air Force Base are the state's major installations, and Kansas allows a nonmilitary spouse to elect the servicemember's state of legal residence under MSRRA for Kansas tax purposes.
Airline Crew
In Delaware
Delaware has no major hub airport for airline crew bases, though its proximity to Philadelphia International makes Delaware a common domicile choice for crew who want to avoid Pennsylvania's local wage taxes. The federal carve-out under 49 U.S.C. § 40116 (crew wages taxable only by the state of residence or a state earning over 50% of pay) governs regardless.
In Kansas
Federal law (49 U.S.C. §40116) limits any state's ability to tax an air carrier employee's pay to the employee's state of residence and any state where more than 50% of pay is earned. Wichita is home to significant aviation manufacturing (Textron Aviation, Spirit AeroSystems) but is not a major airline crew base; crew based elsewhere who happen to be Kansas domiciliaries are protected by the federal carve-out from having their full income pulled into a duty-station state's tax.
Tools for This Move
Delaware to Kansas FAQ
I work remotely from Pennsylvania for a Delaware company. Does Delaware still tax my wages?+
Likely yes, if the remote arrangement is for your own convenience rather than something your employer requires. Delaware's convenience-of-the-employer rule treats income as Delaware-source in that situation, which means you may owe Delaware tax on those wages even though you never work physically in Delaware, and you'll want to confirm Pennsylvania grants a credit for the Delaware tax to avoid paying twice on the same income.
Does Kansas use a 183-day rule like some other states?+
No. Kansas has no statutory day-count test at all. A Kansas resident for tax purposes is simply anyone who lives in Kansas, and someone who is temporarily away from Kansas but intends to return is still treated as a Kansas resident the entire time, regardless of how many days that absence lasts.
How does Delaware's 183-day residency test actually work?+
Under 30 Del. C. § 1103, you're a Delaware resident for tax purposes if you maintain a place of abode in Delaware and spend more than 183 aggregate days in the state during the tax year, regardless of where you consider yourself domiciled. This is separate from, and in addition to, being taxed as a resident because you're actually domiciled in Delaware.
I moved from the Kansas side of Kansas City to the Missouri side but kept my old Kansas driver's license. Is that a problem?+
Yes, it's the single most common Kansas residency issue given how many households move within the KC metro across the state line. A Kansas driver's license, Kansas voter registration, or a Kansas Homestead Refund claim on your old house are all direct evidence of continued Kansas domicile, and the Homestead Refund specifically requires full-year Kansas residency, so keeping that claim after moving to Missouri is a clear contradiction if the state ever checks.
I own a beach house in Rehoboth and visit often but live in Maryland. Am I a Delaware resident?+
You could be, if the Rehoboth house counts as a 'place of abode' you maintain and your total time in Delaware across the year exceeds 183 days, even split across multiple visits. Delaware's statutory-residency test doesn't require the home to be your primary residence, just a place of abode you keep, combined with the day count.
Does Kansas tax my Social Security benefits?+
No, as of tax year 2024 Kansas fully exempts Social Security benefits regardless of income, after the 2024 tax reform package repealed the prior $75,000 federal AGI phase-out that used to tax benefits for higher earners.
Does Delaware have an estate tax I need to plan around?+
No. Delaware repealed its estate tax effective January 1, 2018, and has no separate inheritance tax. Only the federal estate tax can apply to a Delaware domiciliary's estate above the federal exemption.
What form do I file if I only lived in Kansas part of the year?+
Part-year residents file Form K-40 along with Part B of Schedule S, which reports the specific dates Kansas residency began or ended and allocates income between the Kansas-resident and nonresident portions of the year.
Does Delaware tax my Social Security or pension in retirement?+
Social Security is fully exempt from Delaware tax. Delaware also allows a pension and retirement income exclusion of up to $12,500 per person for taxpayers 60 or older, covering pensions, 401(k), and IRA withdrawals; amounts above that exclusion are taxed at Delaware's ordinary rates, up to 6.6%.
Is Kansas an aggressive state for residency audits like California or New York?+
No. Kansas is not on the short list of states practitioners and taxpayer forums consistently flag as aggressive on residency, a list dominated by New York, California, New Jersey, Connecticut, Maryland, and Minnesota. Kansas has no day-count test to enforce, so its residency disputes are narrower and concentrate on driver's license, voter registration, and Homestead Refund records rather than a multi-year presence reconstruction.
I'm domiciled in Delaware but work abroad most of the year. Do I still owe Delaware tax?+
You may qualify for Delaware's foreign-residence exception: if within any consecutive 18-month period you're present in a foreign country at least 495 days, present in Delaware no more than 45 days, don't maintain a Delaware abode where your family stays more than 45 days, and aren't a federal government or military employee, Delaware treats you as a nonresident for that period despite your domicile.
Does Kansas have a homestead exemption that lowers my property taxes?+
Not in the Florida sense of a value-reducing exemption. Kansas instead runs the Homestead Refund (Form K-40H), an income-capped rebate of up to $700 for qualifying homeowners who are 55 or older, blind or disabled, or have a dependent child under 18, plus a separate 75% property tax refund for homeowners 65 and older with lower income. Both require full-year Kansas residency to claim.
