ABA practice employment and payroll requirements in Missouri include complete hours-worked records, the $15.00 state wage floor for 2026, weekly overtime review, careful worker classification, withholding and unemployment accounts, 20-day new-hire reporting, and workers' compensation planning around the general five-employee threshold. Missouri's statewide paid-sick-time mandate ended in 2025, but an employer's policies and other leave obligations still need review.

Start with the Missouri day that never fits in a claim

A payroll system becomes useful when it describes the day your employees actually work. A technician may review a program, drive from a school to a family home, wait for access, provide treatment, finish notes, join supervision, and answer a scheduling question after the last visit. Only some of that day produces billable units. The federal hours-worked guidance explains why inter-site travel, required training, waiting, and work an employer allows may still be paid time.

Map ordinary and difficult days for technicians, BCBAs, intake staff, schedulers, and remote employees. Show where time is entered, how mileage is submitted, and how a missed task is corrected without making the employee feel suspected. Missouri and federal advisers should review exemptions, workweeks, regular rates, multiple rates, bonuses, and actual duties. Let employees report all required or permitted work. A manager can improve future scheduling, but should not erase time merely because a payer will not reimburse it.

Missouri's 2026 wage floor is fifteen dollars

The Missouri Department of Labor lists a $15.00 minimum wage for 2026. Covered nonexempt employees generally must also receive overtime under the applicable state and federal rules. Many clinical roles earn more than the floor, yet missing travel, documentation, training, waiting, or a nondiscretionary incentive can still understate total pay or the regular rate used for overtime.

Write down the workweek, paydays, rates, cancellation expectations, expense process, and correction route in language a new hire can follow. Before launch, test a demanding week with a long drive, an evening supervision meeting, notes completed at home, and a productivity payment. Counsel and the payroll adviser should confirm the exemption, overtime calculation, deductions, statement design, and record retention. The annual wage rate also deserves a dated review rather than a permanent value buried in payroll settings.

The statewide sick-time rule ended, but promises remain

Missouri's statewide earned paid sick-time mandate stopped on August 28, 2025. The state's current repeal FAQ says employers may continue offering the benefit but are no longer required to do so under that repealed statewide requirement. That answer does not cancel a practice's handbook, offer letter, PTO policy, collective agreement, disability or accommodation duty, or another law that applies to a particular employee.

Decide what the practice will actually offer, explain how time is requested and recorded, and keep health information out of ordinary scheduling threads. If an older policy copied the repealed accrual language, do not silently switch it off. Have Missouri counsel review the commitment, effective date, notice, carryover, payout language, rehire treatment, and interaction with protected leave. A clear and usable policy is better for employees than either an outdated legal summary or an unwritten promise supervisors apply differently.

A 1099 label does not settle Missouri classification

Missouri unemployment guidance applies a 20-factor analysis focused on the right to control the manner and means of the work. The state's reportable-work guide says no single factor is conclusive and the substance of the relationship matters more than its label. Federal tax uses the related IRS common-law framework, while wage and workers' compensation questions may require their own review.

Prepare a role memo describing who finds families, assigns cases, determines clinical and administrative methods, sets schedules and rates, supplies systems, pays expenses, bears business risk, offers services to others, and can end the relationship. A license, LLC, flexible calendar, or signed contractor agreement is only part of the evidence. ABA clinicians often perform the central service the practice sells under its documentation and quality systems, so obtain advice grounded in real operating facts. Revisit the memo as control or caseloads change.

Registration is the beginning, not the payroll control

Missouri's business registration portal supports registration for employer withholding and unemployment accounts, while the withholding resources provide current forms, filing information, and tax tables. Save the account numbers, filing frequencies, employee elections, portal administrators, accepted returns, payments, and agency correspondence somewhere the practice can recover without relying on one vendor login.

Location matters for remote and traveling employees, so capture residence and every regular work state before the first payroll. A payroll provider can calculate from the data it receives, but the practice must supply correct legal names, Social Security numbers, work locations, wages, and status. Run a zero-dollar and a normal payroll in test mode. Then reconcile gross wages, withholding, employer taxes, deductions, direct-deposit funding, and the general ledger rather than treating a green vendor dashboard as the whole record.

The 2026 unemployment numbers are modest but exact

The Missouri 2026 UI page lists a $9,000 taxable wage base and a 2.376 percent rate for new employers in the "all others" category after the applicable contribution-rate adjustment. The account's assigned rate and classification control. Missouri still requires all reportable wages even after an employee crosses the taxable base, and a practice should retain both the quarterly acceptance and evidence of payment.

Before filing, compare every employee's identity, gross wages, taxable wages, hire and separation dates, and quarter total with the payroll register and ledger. Review benefit-charge notices promptly because they can affect experience rates. If the practice acquires another entity, adds an out-of-state team, or changes ownership, ask the agency and advisers about successor and multistate rules before moving payroll. Those are legal account questions, not fields a software migration should decide by default.

The fifth employee changes workers' compensation, not the risk

Missouri generally requires workers' compensation at five or more employees; construction businesses generally need it at one. The Division's employer guidance also explains that smaller employers may elect coverage and that an exempt employer without it remains exposed to civil suits from injured workers. Headcount should include the people and owners the statute treats as employees, not only full-time clinicians.

Home, school, center, and community services involve driving, lifting, unfamiliar spaces, exposure, and behavioral risk from the first shift. Ask a licensed broker and counsel about voluntary coverage, owners, class codes, estimated payroll, multistate endorsements, notices, injury contacts, and claim reporting before deciding to wait for the legal threshold. Missouri new and rehired employees are generally reported within 20 days through the state new-hire system. Save the accepted report inside a complete onboarding record.

A fictional St. Louis rehearsal reveals an old policy

Gateway Grove Behavior is a fictional practice preparing two technicians and a BCBA for home and school services around St. Louis. Its payroll worksheet includes session hours and a copied 2025 sick-time policy. A rehearsal adds travel, evening notes, supervision, the 2026 wage floor, one proposed contractor, UI wages, a new-hire deadline, and the question of voluntary workers' compensation below five employees.

The owner keeps the promised leave while counsel reviews future wording, documents classification, registers the tax accounts, reports the hires, and asks a broker to price coverage. Payroll traces the same facts from timecards to employee pay, quarterly wage detail, the ledger, and bank funding. This fictional example is not a customer story or compliance conclusion. It shows how one mock payroll can expose a stale policy and an insurance decision before employees rely on either.

Close payroll in a way people can trust

Every pay period, compare the schedule with reported travel, documentation, training, supervision, waiting, cancellations, leave, rates, incentives, overtime, deductions, and corrections. Preserve original time entries and give employees a private way to ask questions. Monthly, reconcile the roster, work locations, insurance status, new-hire confirmations, portal access, and unresolved agency mail.

Quarterly, tie withholding and unemployment reports to payroll registers, the general ledger, and bank payments. Annually, refresh the wage floor, job descriptions, classification memos, leave promises, UI rate, workers' compensation decision, notices, and vendor permissions. Recheck sooner after remote hiring, an acquisition, a new center, or a compensation redesign. A dependable payroll process is not a single checklist completed at launch. It is a short, repeatable conversation between operations, employees, payroll, and qualified advisers.
