About Client
Client is a professional services firm providing payroll processing, fractional HR, business consulting, and retirement administration for growing businesses.

Our team is hands-on, relationship-driven, and deeply committed to delivering reliable support to the businesses we serve.
Role Overview
Client is looking for a sharp, experienced Payroll Specialist / Admin to serve as a key right-hand resource to our team. In this role, you will be the primary point of contact for a portfolio of trusted clients, handling payroll review, compliance questions, and day-to-day support. You will not be processing payroll directly — our clients submit their own payroll runs — but you will be reviewing submissions for accuracy, flagging issues, and providing expert-level guidance on payroll rules, taxes, and compliance.
This is a role for someone who knows payroll inside and out.

- Reconcile weekly payroll numbers against pre- and post-tax benefit deductions including 401k, FSA, HSA, Group Term Life, and other voluntary and involuntary deductions
Log into client 401k and benefits reporting systems to enter and submit deduction amounts each payroll cycle
- Ensure accurate calculation and handling of pre-tax vs. Roth (post-tax) contributions and deductions
Provide application and navigation support on ADP RUN — guiding clients on how to locate reports, make configuration changes, and resolve system questions
- Handle client inquiries via phone and email on payroll processing, payroll taxes, deductions, garnishments, and compliance
Support bookkeeping and reconciliations in QuickBooks Online
- Assist with HR administration, benefits administration, and client onboarding as needed
Maintain accurate, organized client records and documentation

Candidates must demonstrate a strong working knowledge of the following payroll concepts:
- Multi-state payroll processing and compliance
FICA — Social Security and Medicare tax calculations and employer/employee splits
- Federal, state, and local income tax withholding and remittance
Garnishments and wage assignments — setup, calculation, and compliance
- Pre-tax deductions — 401k, FSA, HSA, health insurance premiums, Group Term Life
Post-tax / Roth contributions and after-tax benefit deductions
- Benefit accruals and reconciliations — matching payroll deductions to benefits reporting systems
Voluntary and involuntary deductions — proper classification and processing
- Wage and hour laws — federal and state overtime rules, pay frequency requirements
Payroll compliance and reporting — timely tax filings, year-end W-2 processing, and regulatory adherence
Required Qualifications
- Bilingual — English and Spanish fluency required (written and verbal)
Minimum 3+ years of hands-on payroll processing or payroll support experience
- Must be able to work on-site 5 days per week at the Miami Lakes, FL office
Experience with ADP RUN — required

Comfortable managing high-volume, deadline-driven workload — 10 to 30 payroll submissions per day
- Excellent client-facing communication skills — professional, responsive, and able to explain complex payroll topics clearly
Highly organized with strong attention to detail and ability to manage multiple accounts simultaneously
- Self-starter who can take full ownership of an assigned client portfolio independently
Nice to Have
HR administration or benefits administration background
- Experience with 401k plan administration and benefits reconciliation
