Withholding Formula (Effective Pay Period 20, 2015)
- Subtract the nontaxable biweekly Thrift Savings Plan contribution from the gross biweekly wages.
- 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.
- Add the taxable biweekly fringe benefits (i.e., taxable life insurance) to the amount computed in step 2 to obtain the adjusted gross biweekly wages.
- Multiply the adjusted gross biweekly wages times 26 to obtain the gross annual wages.
- Using the employee's filing status, subtract the appropriate personal exemption amount from the gross annual wages to determine the employee's taxable income. If the result is less than or equal to zero, the initial withholding amount is zero and proceed to step 11.

If the Employee's Filing Status is Option D: Married - Filing Jointly, Both Spouses Working (Combined Income Greater Than $100,500) or The Employee has not Filed a Valid Form CT-W4
If the Amount of Annual Wages Is:
Multiply the Annual Gross Tax Amount By:
Over $0 and over
0%
- Subtract the Annual Tax Credit calculated in step 9 from the Annual Gross Tax amount calculated in step 8 to determine the employee's Annual Tax Due amount.
- Divide the annual Connecticut tax withholding by 26 to obtain the biweekly Connecticut tax withholding.
- Subtract the biweekly reduced withholding amount (reflected on line 3 of the CT-W4) from the result of step 11 to obtain the biweekly Connecticut tax withholding.
- Add additional amount or percentage elected by the employee to the pay period tax calculated in the above step to determine the amount of tax to be withheld for this pay period.
Note: If the employee does not specify a reduced withholding amount, the biweekly Connecticut tax withholding will be the amount computed in step 11.
