How to Hire Employees in South Carolina: The Complete Compliance Sequence

The first time I helped a founder in the Upstate put someone on payroll, we lost four days to a single missing step. Not the I-9. Not the tax forms. E-Verify. He assumed it was optional, because it is optional under federal law for most private employers. In South Carolina it is not. It is a licensing condition, and the state agency that enforces it can suspend the licenses his business needs to open its doors.

That is the pattern with South Carolina hiring. The federal layer looks familiar and the state layer quietly raises the bar in three or four specific places. Registration is split across three agencies, and signing up with one does nothing for the other two. Workers’ compensation kicks in at a fixed headcount. Wage notices are statutory, not a courtesy. And the penalty for getting final pay wrong is treble damages, which means three times the unpaid wages.

This guide walks the sequence in the order the work actually happens: what you do before you post the job, what you do the week of the offer, what you do on Day 1, and what has to be finished by Day 20.

Every number below was checked against the state agency, the South Carolina Code or another primary source, not carried over from a generic multi-state template. I built FirstHR because the deadlines are the hard part, not the rules.

South Carolina Hiring at a Glance: Every Deadline in One Place

Every South Carolina hiring obligation has a named agency, a hard deadline and a stated consequence. The table below puts the whole compliance surface for a first hire in one place, each obligation with its deadline, penalty and agency.

Three of those obligations are South Carolina rules with no federal equivalent: mandatory E-Verify for private employers, the written wage notice at the time of hiring (once you have had five or more employees in the preceding twelve months), and the four employee workers’ compensation trigger. The rest of this guide takes them one at a time.

Step 1: Get Your Federal Employer Identification Number

You cannot run payroll or open a South Carolina tax account without a federal Employer Identification Number (EIN). Apply online through the IRS EIN application. You complete it in one session, it expires after 15 minutes of inactivity, and the IRS issues the number immediately, so this step never needs to sit on a critical path.

If you formed an LLC or corporation and already have an EIN, reuse it. If you have been operating as a sole proprietor with no employees and filing under your Social Security number, you need an EIN now. Both South Carolina registrations in the next two steps ask for it.

Step 2: Register with the SC Department of Employment and Workforce

The South Carolina Department of Employment and Workforce (DEW) administers unemployment insurance, and you register through the State Unemployment Insurance Tax System, the portal DEW calls SUITS.

The liability test has two triggers. You become a covered employer under Section 41-27-210 of the South Carolina Code once you pay $1,500 or more in wages in a calendar quarter in the current or preceding year, or once you have at least one individual in employment for some part of a day in each of 20 different calendar weeks, which in plain terms means one employee working at all during 20 separate weeks.

Most businesses cross the $1,500 quarterly line with their first full time hire, so treat the registration as a pre-hire task rather than a wait-and-see one. Once the account exists you file a quarterly wage report and pay contributions on the taxable wage base for each employee.

DEW assigns new employers a fixed entry rate until the business has twelve months of liability on record, after which the rate is recalculated from actual benefit experience. Your rate is not something you choose. It is assigned, and it follows your unemployment claims history.

The 2026 figures come from two places. The Department of Labor summary of state unemployment insurance laws puts the South Carolina new employer rate at 1.00 percent for January 2026, with experience-rated employers running from 0.00 percent to 5.40 percent, and Section 41-27-380 caps the taxable wage at the first $14,000 each employee earns in a calendar year.

DEW’s own 2026 contribution table adds a 0.06 percent Departmental Administrative Contingency Assessment to every rate class. A new employer’s total effective rate is therefore 1.06 percent, or at most $148.40 per employee on that $14,000 wage base.

Step 3: Register with the SC Department of Revenue for Withholding

South Carolina taxes wage income, so you also need a withholding file number from the South Carolina Department of Revenue (SCDOR) before the first paycheck. The agency states the test plainly: every employer that has an employee earning wages in South Carolina and that is required to file a withholding return with the IRS is also a withholding agent in South Carolina.

Apply on MyDORWAY, the SCDOR online portal, or file Form SCDOR-111, the Tax Registration Application. The file number is the identifier you reference on every return, payment and piece of correspondence.

Form WH-1605 covers the first three quarters and is due April 30, July 31 and October 31, and Form WH-1606 covers the fourth quarter and the annual reconciliation together, due January 31. Full instructions and the current forms are published on the SCDOR withholding page.

Step 4: Enroll Your Business in E-Verify Before the First Offer

South Carolina requires every private employer in the state to enroll in E-Verify. Section 41-8-20(B) of the South Carolina Code requires a private employer to register and participate in the federal work authorization program and to verify the work authorization of every new employee within three business days after employing that person.

The statute leaves no room to opt out. There is no small employer carve out and no industry exemption, and Section 41-8-20(A) treats the right to employ anyone in the state as an implied South Carolina employment license that stays in effect only while you comply. Public employers and their contractors sit under a separate verification statute.

Enrollment is free and happens at E-Verify.gov. You sign a memorandum of understanding (the program’s user agreement), designate at least one program administrator, and complete the required tutorial. Plan for a couple of days rather than a couple of minutes, and do it before you extend an offer so the three business day clock never catches you mid-enrollment.

Step 5: Complete Form I-9, Then Run the E-Verify Case

Form I-9 comes first and E-Verify comes second. Every employer in the United States must complete Form I-9 for each new employee, and in South Carolina the E-Verify case is built from the data the employee already entered on that form. Reversing the order breaks the process.

Section 1 belongs to the employee and is due on or before the first day of work. The employee supplies name, address, date of birth and status, and attests to work authorization.

Section 2 belongs to you and is due by the end of the third business day after the employee starts. You examine the original documents that establish identity and work authorization and record them on the form. You never tell the employee which documents to bring.

Physical examination is the default rule, and South Carolina employers have an option that hinges on E-Verify. An employer participating in good standing may use the alternative procedure from the Department of Homeland Security instead: examine copies of the documents, hold a live video interaction with the employee, and retain clear copies.

The alternative procedure carries a consistency rule. If you offer it at a hiring site, offer it to every employee there. You may instead limit it to remote hires, as long as the limit is not discriminatory.

The E-Verify case runs on the same three business day clock. Create it after Section 2 is complete, save the case number and the result, and store both with the I-9 rather than in the personnel file.

If the case returns a tentative nonconfirmation, meaning E-Verify could not confirm work authorization automatically, notify the employee in writing and give them the chance to contest it. You cannot terminate, suspend, delay training or withhold pay while a case is being contested.

Step 6: Collect Both Withholding Certificates and Deliver the Wage Notice

South Carolina new hires complete two withholding certificates, not one: the federal Form W-4 and Form SC W-4, the state Employee’s Withholding Allowance Certificate. Both are due before the first wage payment. If either is missing, you withhold at the defaults: single with no adjustments on the federal form and zero allowances on the state form. That almost always overwithholds and generates a payroll correction request in week two.

The state adds a third document that most out-of-state guides omit entirely. Section 41-10-30 of the South Carolina Code requires an employer to notify each employee in writing at the time of hiring of the normal hours and wages agreed upon, the time and place of payment, and the deductions that will be made from wages.

Posting is the one alternative the statute allows. An employer may satisfy the requirement by displaying those terms conspicuously at or near the place of work instead of issuing individual notices. Under Section 41-10-80, a first offense draws a written warning from the Department of Labor, Licensing and Regulation, and a civil penalty of up to $100 attaches to each later one.

Read Section 41-10-20 before you decide you are exempt. The notice section does not reach employers of domestic labor in private homes, or employers that had fewer than five employees at all times during the preceding twelve months, so a genuine first hire often sits outside it.

The exemption ends once you have had five employees at any point in a twelve month stretch, and the notice is cheap evidence either way.

The practical move is to fold the notice into the offer letter. Put the hourly rate or salary, the schedule, the pay frequency, the pay date, the pay method and an itemized deduction list on the same page the candidate signs to accept. That single document then satisfies the statute and doubles as your evidence if a wage dispute ever surfaces.

Here is that content as a block you can paste under the compensation paragraph of your offer letter, or issue on its own if the offer already went out.

What worked for me

We stopped sending offer letters and wage notices as separate attachments. One document, one signature, one timestamp. The offer letter carries the Section 41-10-30 content in a short table right under the compensation paragraph, and the signed copy files itself against the employee record. It removed an entire category of “did we ever send that” from our new hire paperwork process.

Step 7: File the New Hire Report Within 20 Calendar Days

South Carolina gives you 20 calendar days from the date of hire to report a new employee. Section 43-5-598 requires an employer who hires someone who resides or works in the state to report the hire to the state directory of new hires, which the Department of Social Services (DSS) establishes and maintains. A rehire counts as a new hire once the employee has been separated for at least 60 consecutive days.

The report is short. You supply your business name, address and federal EIN, plus the employee name, address, Social Security number and date of hire. Filing is online through the state new hire portal, with mail and fax fallbacks.

The directory exists mainly for child support enforcement, and federal law also opens it to the agencies that run unemployment insurance, which is why DEW draws on the same data.

Penalties start at the second offense and run up to $25 per offense, and rise to as much as $500 per offense where the state finds the failure resulted from a conspiracy between employer and employee to withhold or falsify the information.

The amounts are small. The audit trail they create is not, because a pattern of late reports is exactly the kind of finding that widens a state review into other areas. Filing on the same day you complete the I-9 removes the risk entirely, and it fits naturally into a new hire reporting routine.

Step 8: Secure Workers’ Compensation Coverage at the Right Headcount

Workers’ compensation coverage is mandatory in South Carolina once you regularly employ four or more workers in the same business in the state. That is a headcount trigger rather than an industry one, so a four-person office crosses it on the same day a four-person crew does.

The rule is written as an exemption rather than a mandate. Section 42-1-360 puts outside the act any person who has regularly employed in service fewer than four employees, along with any employer whose total annual payroll during the previous calendar year was less than $3,000 regardless of the number of persons employed.

Two details trip founders up. Part time employees count. So do family members on the payroll, as the Workers’ Compensation Commission confirms. The statute counts people regularly employed, not full time equivalents, so a shop with two full time staff and two part time weekend workers is at the threshold, not below it.

The consequence for going uninsured is set out in Section 42-5-40. The employer is punished by a fine of one dollar for each employee at the time the insurance became due, but not less than $10 nor more than $100 for each day of the refusal or neglect.

The bigger exposure is injury liability. The employer remains liable to an injured employee either for compensation under the act or in a damages action at law, and in that action the statute strips away the common law defenses an employer would normally have.

Step 9: Post the Required Federal and South Carolina Notices

Federal and South Carolina law both require physical workplace postings in a common area that all employees can see. South Carolina runs its own OSHA-approved state plan through the Department of Labor, Licensing and Regulation, so the safety posting comes from the state rather than from federal OSHA.

Every one of these is a free download from the issuing agency. Do not pay a subscription vendor for a laminated set you can print. If you operate from more than one site, each site needs a full set, and remote employees should receive electronic copies with the rest of their onboarding documents.

Step 10: Onboard From Day 1 Through Day 90

Compliance gets someone legally onto your payroll. Onboarding decides whether they are still there in a year. According to Gallup (2021), only 29 percent of new hires say they feel fully prepared and supported to excel in their role after their onboarding experience, and Gallup describes onboarding as the stage where an employer fulfills the promises made during recruitment.

The mechanical goal is simple: finish every form before Day 1 so the first day is about the work and the people. Offer letter, wage notice, both withholding certificates and direct deposit authorization can all be collected digitally in advance, and I-9 Section 1 can be finished before Day 1 as well. That leaves Section 2, the E-Verify case and the new hire report as the only compliance items competing with the first week.

I built the AI onboarding wizard in FirstHR around exactly this shape. Documents go out with e-signature before the start date. Form I-9, W-4, and SC W-4 go on the new hire’s first-day list as tasks, and completed forms are kept in their employee file; the forms themselves are completed outside the platform.

The 20 day new hire report can sit on the same list as a task with its own due date, and the wizard drafts a 30-60-90 day plan from the job description so the manager is not writing one from scratch on a Sunday night. FirstHR is an onboarding and HR platform, not a payroll provider, so it sits alongside whatever payroll system you register with the state.

South Carolina Specific Rules Every Employer Should Know

Six state rules change how you write your offer letters, your employee handbook and your termination process. Most of them add something federal law does not require.

The handbook rule deserves a closer look. Section 41-1-110 says a handbook or personnel manual issued by an employer does not create an express or implied contract of employment if it is conspicuously disclaimed.

The statute defines conspicuous with unusual precision: the disclaimer must appear in underlined capital letters on the first page of the document and be signed by the employee. Whether the disclaimer is conspicuous is a question of law, which means a court decides it on the face of the document. A disclaimer buried on page four is a disclaimer that does not exist.

What worked for me

The rule that cost us real money was final pay. Section 41-10-50 gives you 48 hours or the next regular payday, and Section 41-10-80 lets a former employee recover three times the unpaid wages plus costs and attorney fees, with a three year window to file. We once disputed about $600 of accrued commission. The math on treble damages plus fees made that a very short conversation. Now the final check is calculated before the meeting is scheduled, not after.

Nick Anisimov, FirstHR founder

Headcount triggers one more notice obligation, this time at the state discrimination threshold. The South Carolina Human Affairs Law covers employers with fifteen or more employees for each working day in each of twenty or more calendar weeks in the current or preceding year.

Its pregnancy accommodation provisions require written notice of the right to be free from discrimination for medical needs arising from pregnancy, childbirth or related conditions, delivered to new employees at the start of employment and posted conspicuously at the place of business. Growing past that threshold is a handbook trigger, not just a headcount milestone.

City and County Requirements in South Carolina

South Carolina sets employment rules at the state level, and on pay the state explicitly overrides local rules, a legal move called preemption. Section 6-1-130 bars any political subdivision, including a municipality, county, school district or special purpose district, from establishing, mandating or otherwise requiring a minimum wage rate above the federal rate, with a narrow exception for wage rates written into contracts the government itself is a party to.

The practical guidance for a multi-site South Carolina employer is that your employment policies rarely need to vary by city. What does vary is licensing, which every municipality administers against the same May to April license year. Check the license, read the local ordinance if someone waves one at you, and keep the labor rules statewide.

Employee or Independent Contractor: The Classification That Compounds

Misclassifying an employee as an independent contractor is the most expensive hiring mistake available to a South Carolina small business, because the cost compounds across four agencies at once. South Carolina applies a right to control test rather than the stricter ABC test used in California and Massachusetts, weighing the right to control the work, the method of payment, who furnishes equipment, and the right to fire.

The stack of exposures is what makes this different from a paperwork error. A reclassification means unpaid unemployment insurance contributions with interest at DEW, unpaid state withholding at SCDOR, unpaid federal employment taxes at the IRS, and an uninsured injury exposure if the worker gets hurt and turns out to have been an employee all along. A genuine contractor engagement is fine. A W-2 relationship wearing a 1099 label is not.

The Mistakes That Cost South Carolina Small Businesses the Most

These are the failures I see repeatedly, and several of them come from the calendar rather than from not knowing the rule. The founder knows the I-9 is due. The third business day simply arrives during a week when three other things caught fire.

The common thread is that the deadlines that matter most are short and front-loaded. Three business days for I-9 and E-Verify. Twenty calendar days for the new hire report. Forty-eight hours for a final check. None of them can be recovered by working harder later, which is why a task list with dates beats a compliance binder at small business scale.

This is that task list. The first sheet is one row per hire, with the date each item is actually due written next to the date it was actually done. The second is the set of registrations you do once, with the account numbers you will otherwise hunt for every quarter.
