ABA practice employment and payroll requirements in South Carolina include complete work records under federal wage rules, written pay terms for covered employers, fact-specific worker classification, withholding and unemployment registration, a 2026 UI wage base of $14,000, workers' compensation planning around the general four-worker threshold, 20-day new-hire reports, and South Carolina's three-day E-Verify requirement.

Follow the South Carolina workday, not just the appointment

An ABA employee's day often begins before the first billed unit and ends after the last one. Materials are prepared, schools and homes are visited, access delays happen, notes are completed, supervision takes place, and schedule changes arrive. The federal hours-worked fact sheet explains why required training, travel between job sites, waiting, and permitted work may count as compensable time even when a payer never sees it.

Write examples for technicians, BCBAs, intake staff, schedulers, and remote workers. Show how each person reports time, mileage, canceled-session duties, and corrections. South Carolina and federal counsel should review actual duties, exemptions, workweeks, multiple rates, incentives, and deductions. Employees should record work rather than decide whether a task was billable. If a manager wants to limit after-hours activity, that is a future workflow and supervision issue, not a reason to omit work the practice already required or allowed.

Federal wage rules do most of the floor-setting

South Carolina's wage guidance says the state has no general minimum-wage or overtime law, so the federal Fair Labor Standards Act supplies the main floor for covered employment. The federal state-rate table lists South Carolina under the federal $7.25 rate. Clinical pay is commonly higher, yet off-schedule work and an incorrect regular rate can still create wage problems.

Define the workweek, paydays, rates, bonus terms, travel treatment, expense process, and correction path in ordinary language. Rehearse a week containing an inter-site drive, evening supervision, documentation at home, and a nondiscretionary incentive. Ask counsel and the payroll adviser to confirm coverage, exemption status, overtime, deductions, and records from the job as performed. A salary, clinical credential, or high hourly rate does not by itself answer whether overtime rules apply.

South Carolina's written pay terms deserve attention

The same state wage publication says employers with five or more employees must notify employees in writing at hire of agreed wages, the time and place of payment, and deductions, including insurance programs. Changes generally require written notice at least seven calendar days before taking effect, and each pay period needs an itemized statement of gross pay and deductions. Smaller practices should still value equally clear written terms.

Make the offer letter, wage notice, handbook, payroll configuration, and pay statement agree. Explain multiple rates, bonuses, cancellations, expense reimbursement, direct deposit, and the process for reporting an error. If the practice offers vacation, sick time, or other benefits, document the policy it can consistently administer. Counsel should review whether headcount, separation pay, or another fact changes the rule. Clear notices prevent payroll surprises and give supervisors something more reliable than memory when employees ask questions.

Classification is about the relationship the practice built

South Carolina UI audits verify both reported wages and worker classification. The DEW audit guidance makes clear that businesses with or without an active account can be reviewed. Workers' compensation separately considers control, equipment, method of payment, and the right to fire. Federal tax uses the IRS common-law analysis. A 1099 or contractor clause cannot make all of those systems agree.

Document who obtains families, assigns cases, controls methods and schedules, supplies systems, sets rates, bears expenses, can profit or lose, serves other clients, and controls continuation. Seek advice for employment, UI, tax, workers' compensation, payer, and insurance purposes. ABA practitioners may choose portions of their calendars while still working inside the practice's core service and quality controls. Revisit the analysis when an occasional engagement becomes a continuing caseload or the practice adds supervision, training, documentation, and performance expectations.

MyDORWAY and SUITS solve different obligations

The South Carolina hiring guide directs employers to obtain a withholding account through MyDORWAY and to file with the Department of Employment and Workforce when they have at least one employee so the agency can determine UI liability. The withholding page provides current tables, returns, due dates, and annual wage-reporting resources.

Preserve the state account numbers, assigned filing schedules, employee elections, portal users, accepted returns, payments, and correspondence. Remote work and services across state lines can change wage sourcing, so record where work is actually performed. Reconcile withholding and UI separately to payroll and the ledger. A provider that transmits both files is helpful, but the employer still owns the worker roster, locations, gross wages, taxable wages, accepted filings, and corrections. Never let payer enrollment stand in for employment registration.

South Carolina's 2026 unemployment rate is easy to misread

The 2026 UI rate table applies tax to the first $14,000 of each employee's wages. A new employer is placed in Class 30 at a 1.000 percent base rate plus a 0.060 percent contingency assessment, for a 1.060 percent total effective rate. There is no solvency surcharge for 2026. The agency notice controls if the practice receives a different assignment.

Before each quarterly filing, match legal names, Social Security numbers, hire and separation dates, gross wages, taxable wages, and quarter totals to payroll. Save acceptance and payment evidence, not just a vendor summary. Review quarterly charge statements within the stated protest window and route agency mail to a monitored owner. If the practice acquires another entity or adds a multistate workforce, ask DEW and advisers how experience, liability, and wage localization apply before transferring data.

Four workers, twenty days, and three days are different clocks

South Carolina generally requires workers' compensation when a business regularly employs four or more workers; part-time employees and family members count. The Commission FAQs list exceptions, including employers below four and businesses with annual payroll below $3,000, but the facts and any voluntary election require review. A licensed broker can help evaluate owners, class codes, projected payroll, travel, work states, and coverage timing.

The Business One Stop guide also says new hires must be reported within 20 days and employee work authorization verified through E-Verify within three days of employment under South Carolina law. Those tasks should sit beside federal Form I-9 without being treated as interchangeable. Use authorized procedures, avoid requesting different documents based on citizenship or origin, and retain each confirmation in the proper restricted record. Counsel should review immigration-verification and discrimination practices.

A fictional Columbia practice counts people correctly

Palmetto Pathways ABA is a fictional practice preparing two technicians, a BCBA, and a part-time scheduler around Columbia. The owner initially counts only three clinicians for workers' compensation. A payroll rehearsal adds the scheduler, inter-site travel, evening notes, written wage terms, a proposed contractor, withholding and UI accounts, the 20-day new-hire reports, and the three-day E-Verify process.

The practice asks a broker to bind coverage before launch, has counsel review classification and notices, and gives each hire a private correction route. Payroll ties gross pay, deductions, UI wages, and funding to the ledger. This invented scenario is not a customer result or legal conclusion. It demonstrates why headcount, pay documentation, authorization verification, and reporting must be tested together while remaining separate obligations with separate evidence.

A calm close keeps payroll from becoming detective work

On every payroll, compare scheduled care with travel, notes, training, supervision, waiting, cancellations, benefits, rates, bonuses, overtime, deductions, and corrections. Monthly, reconcile the roster, work locations, workers' compensation count, new-hire and E-Verify confirmations, portal permissions, and agency mail. Keep employee medical and immigration records in the right restricted systems rather than clinical charts or group messages.

Quarterly, tie withholding and UI filings to payroll registers, the ledger, and bank payments. Annually, refresh federal wage rules, written pay terms, classification memos, UI rates, coverage decisions, posters, and vendor access. Recheck sooner after a remote hire, ownership change, new location, or compensation redesign. Payroll software reduces repetition only when the people, locations, and work records underneath it are complete and a named person still reviews exceptions.
