South Carolina Residency Rules: Domicile, Not Days
For income tax, a South Carolina resident is anyone domiciled here: the place you treat as your permanent or indefinite home and intend to return to. There is no day-count test, so time spent in or out of the state does not settle the question on its own. Once you are domiciled here, you stay a resident until you abandon South Carolina and set up a new permanent home somewhere else.
- Section 12-6-30 defines a resident individual as one domiciled in South Carolina.
- SCDOR's Domicile Guide confirms there is no 183-day or minimum-time rule.
- You have one domicile at a time, even if you own several homes.
- What you do counts for more than what you say you intend.
- Leaving takes a real break: a new fixed home and cut ties, not just a long absence.
- Military members and spouses have federal protections that change the usual result.
Who this applies to
- People who split time between a home here and a home in another state
- Anyone who moved to or away from South Carolina and wants to know when residency began or ended
- South Carolinians working abroad or on long out-of-state assignments
- Servicemembers and military spouses stationed in or from South Carolina
Who this may not apply to
- Property tax residency for the 4% legal residence ratio, which has its own application and rules
- Trusts and corporations, which have separate residence definitions in the same statute
The legal test: domicile and intent
Section 12-6-30 of the South Carolina Code says a resident individual is an individual domiciled in this State. A part-year resident is someone who was a resident for only part of the tax year, and everyone else is a nonresident. The statute does not define domicile, so South Carolina courts have filled in the meaning. SCDOR's Domicile Guide, which draws on South Carolina case law, sums it up as the place a person intends to keep as a permanent or indefinite home, and the place they intend to return to when away.
Two things follow from that. First, a residence and a domicile are different. You can own or rent several residences, but you have only one domicile. Second, a domicile continues until it is replaced. A new one exists only when you are physically present in the new place and intend, without conditions, to stay there permanently or indefinitely.
Why there is no 183-day rule
Many people assume that spending fewer than half the year in South Carolina makes them a nonresident. SCDOR's guide says plainly that South Carolina has no 183-day rule and no minimum period of time for establishing or keeping domicile. Days still matter as evidence, because where you spend your time shows where your life is centered, but a low day count does not end South Carolina residency, and a high count does not create it for a seasonal visitor whose permanent home is elsewhere.
The factors SCDOR weighs
Because intent cannot be observed directly, SCDOR looks at conduct. Its guide lists the evidence it considers, and no single item decides the question.
| Category | Examples SCDOR lists |
|---|---|
| Home and property | Addresses on deeds and wills; where your residences are and how you use them; whether you claimed the 4% legal residence assessment ratio on a South Carolina home |
| Work and money | Where you are employed; the address on tax returns; where your bank accounts are |
| Government records | Voter registration; vehicle registration; driver's license; professional licenses |
| Family and community | Where your spouse and children live; civic and social memberships; place of worship; library card |
| Services | Where your doctors, lawyers, accountants and other professional advisers are |
Conduct outweighs declarations
A statement that you consider another state home will not carry much weight if your spouse, your house, your doctors and your bank all stay in Charleston. SCDOR's guide points to the case of Brown and Hodson v. Charleston County Assessor, involving a Kiawah Island home, as an example of how the 4% ratio claim and the rest of a taxpayer's conduct are read together. The burden of proving a change of domicile is on the person who says it changed.
Leaving South Carolina
Leaving is harder than arriving. According to SCDOR, a South Carolina domiciliary who moves away remains a resident unless they do all of the following: abandon the South Carolina domicile, establish a new fixed home in another place, sever their connections here, and move with the intent to stay in the new place permanently or indefinitely. The guide's examples include a resident who takes a job in a foreign country and a long-haul truck driver; both can remain South Carolina residents for years if they keep their ties here and never set up a new permanent home. A vague idea of coming back one day does not by itself defeat a new domicile, but a fixed plan to return usually means the old one never ended.
- Keeping your South Carolina house and the 4% ratio on it while living elsewhere points strongly toward continued residency.
- Moving your spouse and children, voter registration, licenses and bank accounts to the new state points the other way.
- A move that depends on a condition, such as staying only if a job works out, may not be enough to change domicile.
What residency decides on your return
Residents report all of their income to South Carolina, with a credit for tax paid to another state on income that state taxes. Nonresidents report only South Carolina-source income, such as wages for work performed here, rent from South Carolina property and business income allocated or apportioned here. SCDOR's guide adds a point that surprises people: personal service income of a resident is taxable here wherever it is earned. Someone who works in another state but remains domiciled here files as a resident and claims the credit for the other state's tax.
Servicemembers and military spouses
Federal law overrides parts of the domicile test for the military. Under the Servicemembers Civil Relief Act, a servicemember does not gain or lose a domicile just because orders move them, and SCDOR regulations presume that someone domiciled in South Carolina when they entered service remains a resident. SCDOR Revenue Ruling #24-5 explains that from tax year 2023 a servicemember and spouse may each elect to use the servicemember's domicile, the spouse's domicile, or the permanent duty station, and they do not have to live in the elected state. Military pay of a nonresident servicemember is not taxed by South Carolina, though civilian wages earned here and South Carolina rental income or gains are. These protections do not extend to military retirees or former spouses.

Questions people ask about this
Can I be a South Carolina resident if I spend most of the year in another state?
Yes. South Carolina has no 183-day rule. If South Carolina is still the home you intend to return to and your ties are here, you can remain a resident even if you spend most of the year elsewhere.
I own homes in South Carolina and New York. Which state is my domicile?
You have one domicile, and it is decided by the whole picture: where your family lives, where you vote and are licensed, where your doctors and bank are, which home you treat as primary and which home carries any legal residence property tax ratio. Owning two homes does not give you two domiciles.
Does changing my driver's license make me a resident of my new state?
It helps, but on its own it is weak evidence. SCDOR treats easily reversed steps as less persuasive than where your family lives, where you work and which home you actually use as your base.
My spouse is in the military and stationed in Charleston. Do we owe South Carolina tax?
Federal law lets the servicemember and spouse each elect the servicemember's domicile, the spouse's domicile or the duty station. A nonresident servicemember's military pay is not taxed here, but civilian wages a spouse earns here may be unless the spouse elects a domicile outside South Carolina, and South Carolina rental income is taxed either way.

- Filing a part-year SC returnIn the year you move into or out of South Carolina, Section 12-6-1710 gives you a choice. You can report all of your income for the year as if you were a resident and claim a credit for tax paid to the other state, or you can file as a nonresident using Schedule NR, which taxes everything you earned while a resident plus South Carolina-source income from the rest of the year. Which costs less depends on the other state's tax and on when your income arrived.
- Moving to SC: a tax checklistThe tax side of a move to South Carolina comes down to a handful of steps: pin down the date you became domiciled here, get South Carolina tax withheld or paid from that date, apply for the reduced property tax ratio on your new home, and plan your first return as a part-year resident. From 2026 the state return also works differently from the federal one, starting from federal AGI with South Carolina's own deduction and two tax rates.
- The 4% legal residence ratioSouth Carolina taxes the home you own, occupy and are domiciled in on 4% of its fair market value instead of the 6% used for second homes and rentals, and that home is also exempt from school operating millage. The lower ratio is not automatic: you apply to the county assessor, with proof of domicile, before the first penalty date for the first tax year you claim, which is usually January 15 after the tax year.
- SC military retirement deductionSouth Carolina lets a military retiree deduct all military retirement income included in South Carolina taxable income, at any age, under Section 12-6-1171. Surviving spouses can deduct military survivor benefits and dependency and indemnity compensation the same way. H.4216 did not amend Section 12-6-1171, but the military deduction still reduces the retiree's own general retirement and age 65 deductions.
