To pay a 1099 independent contractor in South Carolina, have them complete Form W-9 first, pay them without withholding taxes in most cases, remit any backup withholding to the IRS, and file Form 1099-NEC by January 31. The reporting threshold is $600 for payments made in 2025 and rises to $2,000 for payments made in 2026.
So, you’re looking to hire an independent contractor in South Carolina. Understanding the classification between independent contractors and employees is crucial, especially when it comes to payroll and taxes. This classification affects how you pay them and report payments to the IRS. Here’s a step-by-step guide to ensure you handle everything correctly.
Are You Hiring a Contractor or an Employee?
Before hiring, make sure you understand the difference between an independent contractor and an employee according to IRS guidelines. This distinction is critical because it determines how you will manage tax reporting and payroll.
Steps to Hiring an Independent Contractor in South Carolina
1. Have Your Contractor Fill Out Form W-9
Begin by having your contractor complete Form W-9. This form provides you with essential identifying information. Keep this form in your records for at least four years. Pay special attention to the business classification (i.e., sole proprietorship, S corp, etc.) found on line #3 at the top of the form. This helps determine whether you need to file a 1099-NEC come January. Additionally, verify if the contractor is subject to backup withholding (line 2 under Part II). If the contractor doesn’t provide a valid taxpayer identification number (TIN) in Part I, you must deduct backup withholding from their earnings. Failure to do so could leave you liable for uncollected tax. Get the South Carolina W-9 Form Here 
2. Pay Your Contractor
In South Carolina, as elsewhere, you generally don’t withhold taxes from payments to independent contractors. Employers can pay contractors through checks, direct deposit (with authorization), or platforms like PayPal. Many payroll providers offer services to process these payments if you already use them for employee payroll.
3. Pay Any Backup Withholding to the IRS
If there is any backup withholding, remit that amount to the IRS promptly. Additionally, ensure any state taxes withheld are sent to the appropriate South Carolina state taxing authority.
4. Complete Form 1099-NEC
If you pay a contractor more than $600 in a year (for payments made through 2025), and their business entity is not an S corp or C corp, you must file Form 1099-NEC. Starting with payments made in 2026, that reporting threshold rises to $2,000 under the One Big Beautiful Bill Act. If you paid them via a credit card or third-party payment platform like PayPal, the payment entity may issue a 1099-K if specific thresholds are met. Report any federal income tax withheld in Box 4 of the 1099-NEC. Send Copy A of the 1099-NEC to the IRS and Copy B to your contractor by January 31. If this date falls on a weekend, it is due the following Monday. To mail your 1099-NEC to the IRS, include the required cover sheet, Form 1096: Annual Summary and Transmittal of U.S. Returns. For electronic filing, you’ll need a Transmitter Control Code (TCC). If you don’t have a TCC, request one by filing Form 4419 by November 1 of the preceding year. Use the IRS FIRE system for electronic filing, and send Copy B to your contractor either by post or email (with their written consent). Check if you need to send the 1099-NEC to South Carolina, the state where the contractor resides, or where they worked. Consult with your CPA to ensure compliance with state and local laws.

Frequently Asked Questions
Do I withhold taxes when paying a 1099 contractor in South Carolina?
Generally, no. You pay independent contractors their full invoice amount without withholding federal or state taxes. The exception is backup withholding: if a contractor does not provide a valid taxpayer identification number on Form W-9, you must deduct backup withholding from their pay and send it to the IRS.
What form should a contractor complete before I pay them?
Have every contractor complete Form W-9 before their first payment. It captures their legal name, business classification, and taxpayer identification number, which determine whether you need to file a 1099-NEC. Keep the completed form in your records for at least four years.
When is Form 1099-NEC due?
Form 1099-NEC is due by January 31. Send Copy A to the IRS and Copy B to your contractor by that date. If January 31 falls on a weekend, the deadline moves to the following Monday. Mailed filings also need Form 1096 as a cover sheet.
How can I pay an independent contractor?
You can pay contractors by check, direct deposit with their authorization, or third-party platforms like PayPal. If you already run payroll through a provider, many payroll services can process contractor payments alongside employee payroll, which keeps your records in one place at tax time.
How much can I pay a contractor before I need to file a 1099-NEC?
For payments made through 2025, you must file Form 1099-NEC once a contractor receives $600 or more in a year. Starting with payments made in 2026, the One Big Beautiful Bill Act raises that threshold to $2,000, with annual inflation adjustments beginning in 2027.
