Before You Leave South Carolina
File a part-year return, or choose to file as a resident
In the year you move, you can file as a nonresident or as a full-year resident. As a nonresident, file the SC1040 with Schedule NR. You pay tax only on income earned while a resident and South Carolina-source income. Enter your dates of residency at the top of Schedule NR. Choose the method that costs you less.

Update your insurance company first. Return your South Carolina plate after you register the car in your new state. Mail it with Form 452 to SCDMV Plate Turn-In, PO Box 1498, Blythewood, SC 29016-0024. You can also take it to any SCDMV branch, or decommission it online.
Source: SCDMV, License Plate ReturnDo not cancel the insurance while the plate is active
Insurers tell SCDMV when you cancel a policy. If the plate is still active, SCDMV can suspend your license, plate, and registration. You may pay up to $400 to reinstate them. Turn in the plate before you cancel the insurance.

The 4% assessment ratio is only for your legal residence. If the home stops being your legal residence, notify the county assessor within six months. If you do not, the penalty equals the tax paid plus interest.
Source: S.C. Code 12-43-220(c)Expect withholding if you sell South Carolina property later
A buyer must withhold state income tax when a nonresident sells South Carolina real property. With an affidavit stating the gain, the buyer withholds on the gain. Without one, the buyer withholds on the full amount realized. Gain excluded under the federal home sale exclusion is not subject to withholding.
