Accurate. Timely. Hands-Free

Managing payroll taxes is a critical responsibility—and one of the most error-prone areas for growing businesses. Between multi-state filings, shifting tax rules, and strict deadlines, it’s easy to fall behind or make costly mistakes.

At A3M Partners, we offer end-to-end Payroll Tax Compliance services exclusively through our partnership with ADP — a trusted industry leader in payroll solutions. Whether you’re processing weekly or bi-weekly payroll, expanding into new states, or managing remote teams, we ensure your payroll tax obligations are filed accurately, on time, and stress-free.

Why Payroll Tax Compliance Matters

Many businesses assume that running payroll automatically handles tax compliance—but that’s not always the case. Inaccurate filings, late deposits, or misclassifying employees can lead to IRS notices, penalties, and compliance risks.

Here’s what’s at stake without proper payroll tax support:

  • Costly fines from late or incorrect filings (941, 940, state returns)
  • Tax liabilities from misclassified employees or contractors
  • Missed registrations for new states or localities
  • Inaccurate year-end reporting (W-2s, W-3s, 1099s)
  • Payroll tax audits that disrupt operations

Our team brings structure, oversight, and peace of mind to your payroll compliance — so you stay focused on managing your team, not worrying about government deadlines.

What We Deliver

Through our exclusive ADP partnership, A3M Partners provides fully managed payroll tax filing and compliance support. We ensure your payroll system is properly configured, all accounts are registered, and all filings are submitted accurately and on schedule.

From new business setup to multi-state compliance, we help you avoid risk and stay ahead of your obligations.

Our Payroll Tax Compliance Package Includes:

Federal & State Payroll Tax Filings

We manage and monitor all recurring payroll tax filings through ADP, including:

  • Form 941 – Employer’s Quarterly Federal Tax Return
  • Form 940 – Federal Unemployment Tax (FUTA) Return
  • State income tax withholding and unemployment returns
  • Form W-2 and W-3 – Annual wage reporting and reconciliation

ADP files these returns under our guidance, ensuring real-time accuracy, prompt submissions, and complete record-keeping.

ADP Payroll Setup & Optimization

We help you get the most out of your ADP payroll account—whether you’re starting from scratch or refining your existing setup. Our services include:

  • Setting up federal and state tax IDs
  • Mapping payroll codes and departments
  • Linking your ADP system to accounting platforms
  • Reviewing auto-deposit schedules and settings
  • Ensuring audit-ready payroll reports and filing logs

We configure your ADP environment to meet the demands of your business, payroll frequency, and tax complexity.

Multi-State Payroll Compliance

If your team operates across multiple states, we ensure you’re fully registered and compliant in each location. Our multi-state support includes:

  • New state payroll tax registration
  • ADP configuration for state-specific tax rates
  • Local jurisdiction tax tracking (e.g., NYC, SF, Philly)
  • Filing and remitting taxes according to each state’s schedule

With A3M, you can expand your team without increasing your risk.

Employee Classification & Withholding Review

One of the most common (and costly) mistakes businesses make is misclassifying workers. We review your workforce setup in ADP to ensure:

  • Employees are correctly classified as W-2 or 1099
  • Federal and state tax withholding tables are applied correctly
  • Benefit deductions and reimbursements are treated properly
  • New hire reporting is completed for all jurisdictions

We help you avoid IRS scrutiny and protect your business from compliance issues.

Year-End Reconciliation & Reporting

At year-end, we reconcile your payroll accounts and guide ADP’s generation of:

  • W-2s for employees
  • W-3 summary reporting
  • 1099s for independent contractors (if applicable)

We ensure that all reports match your accounting records and tax filings, making tax season clean, clear, and fully compliant.

Who We Serve

Our Payroll Tax Compliance service is designed for businesses that want high-touch, high-accuracy compliance support without having to manage filings internally. We support:

  • Small and mid – sized businesses with W-2 employees

  • Multi-state employers managing distributed or remote teams

  • Healthcare clinics and service-based businesses with salaried and hourly staff

  • Professional firms with changing contractor and employee mixes

  • Startups scaling quickly and hiring across multiple jurisdictions

Whether you’re onboarding your first employee or managing a team across five states, A3M ensures your payroll taxes stay 100% compliant.

Our Process: Integrated. Transparent. Reliable.

We work directly within your ADP platform to manage payroll tax compliance without disrupting your operations.

  • Step 1: Onboarding & Audit – We review your ADP account, employee classifications, and historical filings to identify gaps or issues.

  • Step 2: State & Federal Registration – We register your business for payroll taxes in any missing jurisdictions and link your accounts in ADP.

  • Step 3: Filing Management & Monitoring – We oversee all payroll tax filings through ADP, ensuring accurate deposits and timely returns.

  • Step 4: Quarterly & Year-End Reconciliation – We conduct quarterly reviews of payroll data and reconcile year-end reports (W-2s, W-3s, 940s, 941s) to ensure accuracy.

  • Step 5: Ongoing Support – We provide continuous oversight, respond to IRS/state notices, and assist with any compliance questions that arise throughout the year.

Common Mistakes We Help Prevent

By proactively managing your payroll tax setup, A3M helps you avoid:

  • Missed or late 941 and 940 filings
