However, some states provide guidance that is policy based - not statutory. Indiana provides a policy and North Carolina has specific statutes. If you have a large liquidity event seek the advise of someone the specializes in this area. Both states have some fairly specific guidance.
The following is Indiana's policy:
Full-year residents
If you were a full-year resident of Indiana and your gross income (the total of all your income before deductions) was greater than your total exemptions, you must file an Indiana tax return.
Full-year residents must file Form IT-40, Indiana Full-Year Resident Individual Income Tax Return or Form IT-40EZ for Full-Year Indiana Resident Filers with No Dependents. If you filed a 2010 federal Form 1040EZ, were a full-year resident of Indiana, claim only the renter's deduction and/or unemployment compensation deduction, and have only Indiana state and county tax withholding credits and/or an earned income credit, then you should file the simplified Form IT-40EZ. If you are not eligible to file Form IT-40EZ, have any add-backs or other deductions or credits, you must file Form IT-40.
You are a full-year Indiana resident if you maintain your legal residence in Indiana from Jan. 1 — Dec. 31 of the tax year. You do not have to be physically present in Indiana the entire year to be considered a full-year resident. Residents, including military personnel, who leave Indiana for a temporary stay, are considered residents during their absence.
Retired persons spending the winter months in another state may still be full-year residents if:
- They maintain their legal residence in Indiana and intend to return to Indiana during part of the taxable year,
- They retain their Indiana driver's license,
- They retain their Indiana voting rights, and/or
- They claim a homestead deduction on their Indiana home for property tax purposes.
Indiana allows $1,000 for each exemption claimed on your federal return, plus an additional $1,500 for certain dependent children (see instructions on page 22 for more information). If you did not have to file a federal return, you should complete a “sample” federal return to see how many exemptions you are eligible to claim.
If your gross income is less than your total exemptions, you are not required to file. However, you may want to file a return to get a refund of any state and/or county tax withheld by your employer, or other refundable credits, such as an earned income credit.
Part-year residents and full-year nonresidents
If you were a part-year resident and received income while you lived in Indiana, you must file Indiana Form IT-40PNR, Part-Year Resident or Nonresident Individual Income Tax Return.
If you were a legal resident of another state (exception: see next paragraph) and had income from Indiana (except certain interest, dividends, or retirement income), you must file Form IT-40PNR.

The following is a portion of the applicable law for NC:
6B.3901. Definition of resident.
(a) Only one domicile.—Domicile means the place where an individual has a true, fixed permanent home and principal establishment, and to which place, whenever absent, the individual has the intention of returning. In many cases, a determination must be made as to when or whether a domicile has been abandoned. A long standing principle in tax administration, repeatedly upheld by the courts, is that an individual can have but one domicile; and, once established, it is not legally abandoned until a new one is established. A taxpayer may have several places of abode in a year, but at no time can an individual have more than one domicile. A mere intent or desire to make a change in domicile is not enough; voluntary and positive action must be taken.
(b) Factors.—Some of the tests or factors to be considered in determining the legal residence of an individual for income tax purposes are as follows:
(1) Place of birth of the taxpayer, the taxpayer's spouse, and the taxpayer's children.
(2) Permanent residence of the taxpayer's parents.
(3) Family connections and close friends.
(4) Address used for federal tax returns, military purposes, passports, driver's license, vehicle registrations, insurance policies, professional licenses or certificates, subscriptions for newspapers, magazines, and other publications, and monthly statements for credit cards, utilities, bank accounts, loans, insurance, or any other bill or item that requires a response.
(5) Civic ties, such as church membership, club membership, or lodge membership.
(6) Professional ties, such as licensure by a licensing agency or membership in a business association.
(7) Payment of state income taxes.
(8) Place of employment or, if self-employed, place where business is conducted.
(9) Location of healthcare providers, such as doctors, dentists, veterinarians, and pharmacists.
(10) Voter registration and ballots cast, whether in person or by absentee ballot.
(11) Occasional visits or spending one's leave “at home” if a member of the armed services.
(12) Ownership of a home, insuring a home as a primary residence, or deferring gain on the sale of a home as a primary residence.
(13) Location of pets.
(14) Attendance of the taxpayer or the taxpayer's children at State supported colleges or universities on a basis of residence—taking advantage of lower tuition fees.
(15) Location of activities for everyday “hometown” living, such as grocery shopping, haircuts, video rentals, dry cleaning, fueling vehicles, and automated banking transactions.
(16) Utility usage, including electricity, gas, telecommunications, and cable television.
(c) When change occurs.—The following events indicate a change in residency:
(1) Selling a house and buying a new one.
(2) Directing the U.S. Postal Service to forward mail to a new address.
(3) Notifying senders of statements, bills, subscriptions, and similar items of a new address.
(4) Transferring family medical records to a new healthcare provider.
(5) Registering a vehicle in a new jurisdiction.
(6) Transferring memberships for church, a health club, a lodge, or a similar activity.
(7) Applying for professional certifications in a new jurisdiction.
(d) Military service.—A legal resident of North Carolina serving in the United States Armed Forces is liable for North Carolina income tax and North Carolina income tax shall be withheld from that individual's military pay whether the individual is stationed in this State or in some other state or country. An individual who enters military service while a resident of North Carolina is presumed to be a resident of this State for income tax purposes. Residency in this State is not abandoned until residency is established elsewhere. To change residency, an individual in military service must not only be present in the new location with the intention of making it a new domicile, but must also factually establish that the individual has done so.
