How to choose a payroll company in South Carolina
Where to find payroll companies in South Carolina
Every private employer in South Carolina has to check new hires through E-Verify. That is a separate step from state new hire reporting, so your onboarding paperwork starts before the first paycheck. A good payroll partner here handles both the hiring paperwork and the pay runs.
Most payroll companies are where most employers are. The Upstate around Greenville and Spartanburg, the Midlands around Columbia and the Lowcountry around Charleston have the most firms. Charleston is now the state's largest city, followed by Columbia, North Charleston and Mount Pleasant. In these metros you can choose between CPA firms with payroll departments, independent payroll bureaus and providers that focus on one kind of business, such as restaurants, contractors or medical offices.
In the Midlands, businesses in Irmo and the other Lexington and Richland County suburbs can meet a provider in person without much driving. In Charleston, many employers are in hospitality and the trades, so look for a firm that handles tipped pay and crews that change from job to job. Around Myrtle Beach and the rest of the Grand Strand, the big issue is the season. Staff numbers jump in spring and drop in fall, which means a lot of new hire reports and final paychecks in a short window.
Rock Hill, Fort Mill and the rest of York County are part of the Charlotte metro. If some of your staff live in North Carolina, ask any provider whether it files for both states as a normal part of the service. In smaller markets like Florence, Aiken or Beaufort, you may end up with a regional firm based in a larger city, or a provider that works with you remotely. That can work fine if the provider responds quickly.
South Carolina payroll rules your provider has to get right
State payroll here is fairly simple compared with many states, but some details trip up out-of-state providers.
- State income tax withholding. South Carolina has a graduated income tax, and the top rate has come down in recent years. The Department of Revenue (SCDOR) publishes new withholding tables and a new SC W-4 for each year, so check that your provider updates its tables every January. There are no city or county income taxes to withhold. Employers that withhold $15,000 or more in a quarter, or make 24 or more withholding payments in a year, must file and pay electronically through MyDORWAY.
- Unemployment insurance. New employers register with the Department of Employment and Workforce (DEW). The new employer rate is commonly listed as 1.06% on the first $14,000 of each worker's wages. DEW sets a new rate each year based on your history, and experienced-employer rates range from 0.06% to 5.46%. Confirm current figures with DEW and SCDOR before you sign.
- New hire reporting. You must report each new hire to the state within 20 days of their first day of work. Rehires count too if they were gone for more than 60 days.
- Payment of Wages Act. When you hire someone, you have to tell them in writing what they will be paid, when and where they will be paid, and what deductions will come out. You must give at least seven days' written notice before changing any of that. Final pay is due within 48 hours of separation or on the next regular payday, and no later than 30 days. Courts can award up to three times the unpaid wages for willful violations.
In practice, ask each provider who controls your MyDORWAY and DEW logins, who files the quarterly returns and the annual reconciliation, and how fast it can run an off-cycle check for a final paycheck. Also ask whether it can produce the written wage notice for you. Some providers do, and that saves a lot of trouble.
There is one licensing point to check. If the company is a professional employer organization (PEO), meaning it becomes the co-employer of your staff, it must be licensed by the South Carolina Department of Consumer Affairs, and the license comes with a surety bond. Ask for the license number. If the company only processes payroll, don't assume a state license or bond protects you. Ask about its insurance and how it holds your tax money between collecting it and paying it to the state.
Choosing between local and national payroll providers in South Carolina
National platforms usually win on software and price for a basic payroll. Local firms usually win when something goes wrong. A Columbia bookkeeper who already knows the people at DEW will usually sort out a rate notice faster than a call center will. Many smaller employers want a local firm that runs a well-known national software platform, so they get both.
Decide early how much in-person help you need. A contractor with crew time sheets on paper may need someone to come to the office. A five-person agency that works on laptops probably doesn't. Remote service works well when you can reach the same named person every time.
When you compare quotes, look past the price per pay run:
- Fees for year-end W-2s, extra off-cycle checks, new state registrations and adding employees
- Who pays penalties and interest if the provider files late or files the wrong amount
- How much notice you need to give to cancel, and whether your payroll history comes back to you in a format you can use
- Setup fees, and whether the provider handles the move from your current system
Ask for two references from businesses like yours, in your part of the state, and with about the same number of employees. A restaurant on the Grand Strand will learn more from another seasonal employer than from a law firm in Greenville. Ask those references how the provider handled its first mistake. Every provider makes a mistake eventually. What matters is whether it owned the error and paid any penalty without arguing.
Finally, make sure your first payroll is set up correctly. Check that the withholding tables, your DEW rate and every employee's SC W-4 are entered right before the first live run. Most problems that show up later started at setup.
