Top Payroll Compliance Issues US Businesses Must Avoid in 2025

August 4, 2025

Payroll might seem routine, but it's one of the most compliance-sensitive functions in any US business. From W-2 vs 1099 misclassification to SUI rate errors, small issues can lead to rejected filings, state penalties, or worse, IRS scrutiny.

Let’s explore the most common payroll compliance issues.

Missed or Incorrect State Payroll Registrations

Many companies forget to register in every state where employees are located. This includes:

  • State income tax withholding accounts
  • SUI (State Unemployment Insurance) accounts
  • City payroll taxes (e.g., NY MCTMT, Denver OPT, Ohio SDI)

Risk: Delays in payroll processing, rejected filings, and costly state penalties

Incorrect Payroll Tax Setup

Tools like Gusto, ADP, or QuickBooks can default to the wrong settings:

  • Wrong SUI rate
  • Incorrect work location
  • Missing local taxes (ZIP/address errors)

Risk: Overpayment or underpayment, inaccurate W-2s, and filing errors

Late Payroll Filings

Reasons for delay often include:

  • Missing e-signatures
  • Incomplete payroll platform setup
  • Client-side approval delays

Risk: Late payment penalties, interest charges, and even account deactivation

W-2 vs 1099 Misclassification

Misidentifying employees as independent contractors is one of the most common and costly payroll issues.

  • W-2s = employees (withholding required)
  • 1099s = independent contractors (no withholding)

Risk: IRS penalties, tax reclassification, and employee lawsuits

Multi-State Payroll and Remote Team Oversights

With remote teams, your payroll must comply with:

  • Each state’s registration and tax withholding laws
  • Local labor laws and minimum wage rules

Risk: Payroll rejections, back taxes, and non-compliance fines

Limited Payroll Platform Support

ADP, Gusto, and QuickBooks have limits:

  • No real-time compliance alerts
  • Delayed response to notice, as the notices were placed in queue

Risk: False sense of security, delayed issue resolution & liable for penalties

Lack of Payroll Ownership or Coordination

Without a dedicated payroll compliance partner, you risk:

  • Missed deadlines
  • Unmonitored account notices
  • Improper handling of changes in employee status or location

Not Closing or Updating Payroll Registrations

Common when:

  • You switch payroll providers
  • Shut down a location
  • Employees move to a new state

If not handled properly:

  • Tax accounts remain open
  • You may receive ongoing tax notices and fines
