How do businesses calculate payroll tax withholdings?

Calculating Payroll Tax Withholdings for New Jersey Businesses

In New Jersey, accurately calculating payroll tax withholdings is essential for compliance and smooth business operations. Employers must withhold federal, state, and local payroll taxes from employee wages and remit these amounts timely.

Key Payroll Tax Components to Withhold

• Federal Income Tax: Use IRS tax tables and employee Form W-4 information to determine withholding amounts.
• Social Security and Medicare Taxes (FICA): Withhold 6.2% for Social Security and 1.45% for Medicare from employee wages; employers must match these amounts.
• New Jersey State Income Tax: Calculate withholding based on the New Jersey Employer’s Guide tax tables and employee Form NJ-W4.
• New Jersey Unemployment Insurance (UI): Paid by employers; no employee withholding, but employers must factor this into payroll tax reporting.
• Temporary Disability Insurance (TDI) and Family Leave Insurance (FLI): Employers withhold these employee contributions based on state rates, which can vary annually.

Steps to Calculate Payroll Tax Withholdings

• Gather Employee Information: Obtain federal Form W-4 and New Jersey Form NJ-W4 for accurate tax status and allowances.
• Determine Gross Wages: Calculate total wages for the pay period, including regular pay, overtime, bonuses, and commissions.
• Apply Federal Withholding: Use IRS Publication 15-T tables or payroll software to find the correct federal tax withholding.
• Calculate FICA Taxes: Multiply gross wages by 6.2% for Social Security and 1.45% for Medicare withholding.
• Apply New Jersey State Withholding: Use the New Jersey withholding tables and employee NJ-W4 details to find state income tax withholding.
• Calculate TDI and FLI Withholdings: Apply current New Jersey rates to gross wages subject to these programs.
• Subtract Total Withholdings: Deduct all calculated taxes from gross wages to determine net pay.
