How to Set Up Payroll for a New Business in South Carolina

The first employee changes what a business is, administratively. Up to that point you have income and expenses; afterwards you have withholding obligations, deposit deadlines, filing schedules and a category of liability that can follow individuals personally. Setting it up properly at the start is much cheaper than correcting it later.

Before setting up payroll, be certain the people you are paying are employees. If they are genuinely independent contractors, none of this applies — and if you treat employees as contractors to avoid it, the eventual correction includes back taxes, penalties and interest.

Classification is determined by the reality of the arrangement — how much control you exercise over how, when and where the work is done, whether the worker offers services to others, who supplies tools, and how the relationship is structured. It is not determined by what the parties agree to call it, and a signed contract describing someone as a contractor does not make them one.

If it is genuinely unclear, resolve it before the first payment rather than after the first year.

Register before the first payroll runs. Retrospective registration is possible but it complicates the first filings unnecessarily.

Before the first payment: a federal withholding certificate and its state counterpart, employment eligibility verification with documentation retained, and bank details if paying by direct deposit. New hire reporting to the state follows within its required window.

Keep these together and keep them current. Employees change their withholding elections, and an out-of-date certificate produces withholding that does not match what the employee expects to see.

Pay frequency — weekly, fortnightly, semi-monthly or monthly. Less frequent means less administration; more frequent is what most hourly employees expect. Changing it later is disruptive, so decide deliberately rather than defaulting.

Pay period versus pay date. The gap between the end of a period and the date it is paid needs to be long enough to process hours and approvals. Too short and every payroll is a scramble; too long and employees notice.

How overtime, paid leave and any bonus arrangements are handled — these should be written down before the first dispute rather than after it.

Three broad options. Doing it manually is possible and inadvisable — the calculations are not the hard part, the deposit and filing deadlines are, and missing them is where the cost lands.

Payroll software handles calculation and, in most cases, deposits and filings, at modest cost. It works well provided someone is monitoring that the filings actually happened and that the assigned deposit schedule has not changed.

A full-service provider takes responsibility for the whole obligation, which for most small businesses is the sensible choice — not because the work is difficult, but because the consequences of a missed deadline are disproportionate to the fee.

Setting up payroll is not optional. An owner working in an S-Corp must take a reasonable salary through payroll before taking distributions, and paying yourself entirely in distributions is among the most reliably examined issues for small S-Corps.

It also needs to happen during the year rather than being corrected at year end, which is difficult to do credibly after the fact.
