Employer Payroll Tax Obligations

• Calculate and Withhold Taxes: Use updated tax tables and payroll software to correctly calculate withholding amounts each pay period.
• Deposit Payroll Taxes: Deposit withheld taxes and employer contributions according to IRS and New Jersey schedules, typically monthly or semiweekly depending on your payroll size.
• File Payroll Tax Reports: Submit required quarterly and annual payroll tax returns to both federal and state tax authorities on time.
• Maintain Records: Keep detailed payroll records, including wages, tax withholdings, tax deposits, and filings for at least four years to support audits and compliance reviews.

Additional Considerations

• Employee Classification: Correctly classify workers as employees or independent contractors to avoid payroll tax issues.
• Automation: Consider using payroll software or services that automate tax calculations, deposits, and filings to reduce errors and save time.
• Insurance and Benefits: Coordinate payroll with benefits administration and workers’ compensation insurance to ensure accurate deductions and compliance.
