Withholding Formula >(Massachusetts Effective 2024)<
  1. Subtract the nontaxable biweekly Thrift Savings Plan contribution from the gross biweekly wages.

  2. Subtract the nontaxable biweekly Federal Health Benefits Plan payment(s) (includes dental and vision insurance program, and flexible spending account - health care and dependent care deductions) from the amount computed in step 1.

  3. Add the taxable biweekly fringe benefits (taxable life insurance, etc.) to the amount computed in step 2 to obtain the adjusted gross biweekly wages.

  4. Multiply the adjusted gross biweekly wages times 26 to obtain the gross annual wages.

    5. Note: Do not withhold tax on employees who claim one or more exemptions while making less than $8,000 annually.

  5. Determine the employee's current retirement deduction amount:

    6. a. Multiply the year-to-date state taxable wages (not including current wages) by the
    employee's Federal Insurance Contribution Act (FICA) rate (e.g., 7.65 percent for social security, 1.45 percent for Medicare-only) to obtain the previous year-to-date FICA contribution.

    b. Add the previous year-to-date FICA contribution computed in Step 5a to the employee's year-to-date contribution to all other retirement systems to obtain the previous year-to-date retirement contribution.

    Note: If this amount is greater than $2,000, the current retirement deduction amount is zero. Omit Steps 5c through 5e and proceed to Step 6.

    c. Multiply the current state taxable wages by the employee's FICA rate (e.g., 7.65 percent for social security, 1.45 percent for Medicare-only) to obtain the current FICA contribution.

    d. Add the current FICA contribution computed in Step 5c to the employee's current contribution to all other retirement systems to obtain the current retirement contribution.

    e. Add the previous year-to-date retirement contribution computed in Step 5b to the current retirement contribution computed in Step 5d to obtain the new year-to-date retirement contribution.

    Note: If this amount is greater than $2,000, the current retirement deduction amount is $2,000 minus the previous year-to-date retirement contribution (e.g., $2,000 minus the amount computed in Step 5b).

    or

    If this amount is less than or equal to $2,000, the current retirement deduction amount is equal to the current retirement contribution computed in Step 5d.

  6. Subtract the current retirement deduction amount computed in Step 5, if applicable, from the current adjusted gross biweekly wages computed in Step 3 to obtain the current adjusted gross biweekly wages.

    7. Note: If the employee 's current retirement deduction amount computed in Step 5 is zero, the current adjusted gross biweekly wages is the amount computed in Step 3.

  7. Multiply the current adjusted gross biweekly wages by 26 to obtain the current adjusted gross annual wages.

  8. Subtract the following amounts, as applicable, from the current adjusted gross annual wages computed in Step 7:

    9. a. If the employee claims one exemption only, deduct >$4,400<.

    or

    b. If the employee claims more than one exemption, deduct $1,000 times the number of exemptions plus >$3,400.<

  9. Calculate the annual Massachusetts tax withholding based on the following table.

    11. a. If the employee claims head of household, deduct >$120.00<.

    b. If the employee and/or spouse is blind, deduct $110.00 for each blind exemption.
