How Businesses Calculate Payroll Tax Withholdings in New Mexico

Calculating payroll tax withholdings accurately is essential for New Mexico businesses to maintain compliance and ensure smooth operations. Payroll tax withholdings include federal, state, and local taxes that employers must deduct from employee wages.

Key Payroll Tax Components

• Federal Income Tax: Employers use IRS tax tables and employee W-4 forms to determine the amount to withhold.
• Social Security and Medicare Taxes (FICA): Employers withhold 6.2% for Social Security and 1.45% for Medicare from employee wages, matching these amounts as the employer.
• New Mexico State Income Tax: Employers must withhold state income tax based on New Mexico’s withholding tax tables, which consider filing status and allowances.
• Unemployment Insurance (UI): While UI taxes are generally employer-paid, accurate payroll records are necessary for reporting and rate calculations.

Steps to Calculate Payroll Tax Withholdings

• Collect Employee Information: Obtain completed federal Form W-4 and any relevant New Mexico state withholding forms from employees.
• Determine Gross Wages: Calculate the employee’s total earnings for the pay period, including regular pay, overtime, and bonuses.
• Apply Federal Withholding: Use IRS tax tables aligned with the employee’s W-4 information to calculate federal income tax withholding.
• Calculate FICA Taxes: Withhold 6.2% for Social Security and 1.45% for Medicare on wages up to applicable limits.
