Do I need a state tax registration before opening?

State Tax Registration Requirements in South Carolina Before Opening

In South Carolina, obtaining state tax registration before opening your business is a crucial operational step. This registration allows you to collect and remit state sales tax and fulfill other tax obligations.

When to Register for State Taxes

• Sales Tax Collection: If your business sells tangible goods or taxable services, you must register for a sales tax license with the South Carolina Department of Revenue (SCDOR) before beginning operations.
• Withholding Tax: If you plan to hire employees, you need to register for employer withholding tax to handle payroll tax deductions properly.
• Other Taxes: Depending on your business activities, you may need additional tax accounts, such as for use tax or accommodations tax.

How to Register

As of 2026, you can register online through the South Carolina Business One Stop (SCBOS) portal. This platform streamlines business registration, including tax accounts, business licenses, and permits.

Registering early ensures compliance and avoids delays in operations related to tax collection and reporting.

Operational Considerations

• Recordkeeping: Maintain accurate sales and payroll records to support tax filings and audits.
• Reporting Requirements: Be aware of periodic tax return filing deadlines to stay compliant.
• Automation: Consider using accounting or payroll software that integrates with South Carolina tax requirements to streamline compliance.
