Federal payroll taxes for Massachusetts employers

Let’s go over federal payroll taxes first, shall we? Our handy payroll calculator will help you figure out the federal payroll tax withholding for both your employees and your business.

We’ve organized federal income taxes into a 6-step overview. If you would like to see a more detailed explanation, we invite you to check out ourstep-by-step guide here.

  1. Gross Wages.Always start withgross wages, which represents the dollar amount of earnings an employee has made during the most recent pay period.
    1. For hourly employees, multiply the number of hours worked in the most recent pay period by their pay rate. Make sure to calculate any overtime hours worked at the appropriate rate.
    2. For salaried employees, divide each employee’s annual salary by the number of pay periods you have each year.
    3. And don’t forget about employees who earn commissions, tips, or bonuses. They all get added to gross wages.
  2. Pre-Tax Withholdings.Some of your employees might contribute to a 401(k), flexible spending account (FSA), or otherpre-tax deductions. If so, subtract their contributions from gross pay before you start applying federal payroll taxes.
  3. Federal Income Tax.The biggest tax of them all, which can range from 0% all the way up to a marginal tax rate of 37%. We won’t get into all the little details here. You can find all the information you need through theIRS Publication 15-T.
  4. FICA TaxesSocial Security and Medicare:
    1. Social Security: You need to withhold 6.2% of each employee’s taxable wages until they have earned $168,600 for the year. Any wages above $168,600 are exempt. As the employer, you must match this tax dollar-for-dollar.
    2. Medicare:You need to also withhold 1.45% of each employee’s taxable wages until they have earned $200,000 for the year. You will need to match this tax as well. For employees who earn more than $200,000 in taxable wages, you need to withhold what’s called an Additional Medicare Tax (super original name, right?) of 0.9%. Only the employee is responsible for paying the Additional Medicare Tax, so you don’t have to match it.
  5. FUTA Tax. TheFUTA taxis more commonly known as the unemployment tax, and only employers have to pay this tax, not employees. The tax rate is 6% of the first $7,000 of taxable income an employee earns annually. Note that you can claim atax credit of up to 5.4%for paying your Massachusetts state unemployment taxes in full and on time each quarter, which means that you’ll effectively be paying only 0.6% on your FUTA tax. It definitely pays to save 90% on your tax bill.
  6. Post-Tax Deductions.For most of your employees, you’d be done with their federal payroll taxes at step 5, but some employees may be responsible for paying court-orderedwage garnishmentsor child support. They may also choose to make post-tax contributions to savings accounts, elective benefits (like life insurance), orother withholdings.

Massachusetts employers can quickly calculate their employees’ gross pay, net pay, and deductions using the free calculator at the top of this page (and feel confident when cutting paychecks). But every now and then, employers may have situations that need a little more number crunching. For example, do your best-performing employees get bonuses from time to time? Remember that Uncle Sam considers this type of payment to be supplemental wages and requires taxes to be withheld. Also, if you have workers who come and go, you may need to figure out how much their final paycheck will be.
