Withholding Formula (Effective Pay Period 17, 2025)
- Subtract the nontaxable biweekly Thrift Savings Plan contribution from the gross biweekly wages.
- Subtract the nontaxable biweekly Federal Employees 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.
- Add the taxable biweekly fringe benefits (e.g., taxable life insurance) to the amount computed in step 2 to obtain the adjusted gross biweekly wages.
- Multiply the adjusted gross biweekly wages by the number of pay dates in the tax year to obtain the annual wages.1
1 If gross annualized wages are less than $5,000, taxes will not be withheld. - Subtract the Standard Deduction amount of $3,350 from the gross annualized wages computed in step 4.
- Determine the dependent allowance by applying the following guideline and subtract this amount from the result of step 5 to determine the taxable income:
Multiply the number of Exemptions by $3,200.
- Apply the taxable income computed in step 6 to the following table to determine the annual Maryland tax withholding:
