South Carolina State Tax Forms

Here is a rewritten, expanded, and polished version with a clear recommendation for electronic filing, written in a professional, taxpayer-friendly tone:

South Carolina Individual Income Tax Forms and Filing Options

The primary form used to file a South Carolina individual income tax return is Form SC1040, the state’s Individual Income Tax Return. This form is required for residents, nonresidents, and part-year residents and is used to calculate South Carolina tax liability based on federal taxable income, with state-specific additions, subtractions, and credits.

Before completing your South Carolina return, you should first finalize your federal income tax return, as many figures from the federal return flow directly into Form SC1040.

Key Individual Income Tax Forms

The South Carolina Department of Revenue (SCDOR) provides the following core forms and schedules, all of which are available on its official website:

• Form SC1040 – South Carolina Individual Income Tax Return
  The primary return used by most individual taxpayers to report income, claim deductions and credits, and calculate tax due or refund.
• Schedule NR – Nonresident Schedule
  Required for nonresidents and part-year residents to allocate and report income earned from South Carolina sources. This schedule must be attached to Form SC1040.
• Form SC1040TC – Tax Credits
  Used to claim South Carolina-specific tax credits, such as credits for dependent exemptions, contributions, or other qualifying activities.
• Form SC4868 – Request for Automatic Extension of Time to File
  Allows taxpayers to request an extension to file their return. Important: If you submit a payment electronically through the SCDOR’s MyDORWAY system, the extension request is automatically filed—no separate form is required.
• Form SC1040V – Individual Income Tax Electronic Payment Voucher
  Used when mailing a payment for taxes due with a paper-filed return.
• Form SC W-4 – South Carolina Employee’s Withholding Allowance Certificate
  Completed by employees and provided to employers to determine the correct amount of South Carolina income tax to withhold from wages.

Filing Methods and Recommendation

South Carolina offers several ways to file your individual income tax return:

• Electronic Filing (Strongly Recommended)
  Taxpayers can file electronically using approved commercial tax software or, if eligible, through the SCDOR’s free online portal, MyDORWAY.
  Electronic filing is recommended because it:
  • Reduces errors through automatic calculations and validation checks
  • Speeds up refund processing
  • Confirms receipt of your return and payments
  • Allows secure electronic payment and extension requests
• Professional Tax Preparer
  A licensed tax professional can prepare and electronically file your return on your behalf.
• Paper Filing by Mail
  While still accepted, paper returns take longer to process and are more prone to delays and errors compared to electronic filing.

Additional Information

For the most up-to-date forms, instructions, filing requirements, and guidance, taxpayers should visit the South Carolina Department of Revenue (SCDOR) website. This site also provides access to MyDORWAY, where taxpayers can file returns, make payments, request extensions, and manage their tax accounts online.
