Completing these steps thoroughly helps avoid delays and maximizes your potential refund or savings.

If you are a South Carolina resident for the whole year or only part of the year, you are generally required to file a state income tax return if you are also required to file a federal income tax return. South Carolina residents must report all income earned, including wages, self-employment earnings, and taxable benefits, even if some were earned outside the state. Part-year residents must use the appropriate South Carolina schedule to report only the income earned while living in the state, including those who moved into or out of the Palmetto State during the year.
Depending on age, filing status, and total income, residents may qualify for various deductions and exemptions. For example, seniors and families with dependents may benefit from special adjustments to reduce their taxable income. Calculating income correctly and including documentation to avoid costly errors is essential. Taxpayers should understand whether their income meets the state's filing threshold based on their adjusted gross income and standard deduction eligibility.
Nonresidents must file a South Carolina income tax return if they earned income from a source within the state. This includes wages earned while working temporarily in South Carolina or rental income from South Carolina property. In these cases, the taxpayer must use Schedule NR to determine the portion of income subject to South Carolina taxation. Even if you are a resident of another state or country, you may still owe state tax if you conduct business or generate income within South Carolina borders.

Most individuals must file if their income exceeds the combined value of the standard deduction and exemptions for their filing status. The thresholds generally align with federal guidelines but are adjusted for state-specific rules. For example, an average single filer who earns above the federal standard deduction amount will likely need to file a state return if they are a South Carolina resident.
In addition, some individuals may be required to file even if their income is low. These cases include those claiming refundable credits, recovering withholding, or requesting a refund. Even if your tax bill is zero, filing may result in a refund based on prior payments. Filing ensures compliance, protects your financial records, and may offer future savings. If in doubt, you should consult the South Carolina Department of Revenue or a licensed tax professional to determine your filing obligation.
