Federal Income Tax Withholding

Effective as soon as possible in 2008, payroll checks will reflect the increase in the biweekly personal exemption value for each federal tax allowance from $130.77 to $134.62. Based upon provisions in the Jobs and Growth Tax Relief Recon­ciliation Act of 2003, the six tax percentages remain at 10, 15, 25, 28, 33, and 35 percent, respectively. All information in this article is based upon both a biweekly payroll period (PP) and the withholding tables contained in IRS Publication 15.

Commuter Program Pretax (CPP), Federal Employees Dental and Vision Insurance Program (FEDVIP), Federal Employees Health Benefits (FEHB), Flexible Spending Account (FSA), and Thrift Savings Plan (TSP) contributions made by employees are treated as pretax monies for these computations. When calculating your taxes, remember to subtract your withholding allowances and all of these contribution amounts from your gross earnings.

Note: There are two technical exceptions to this pretax rule. TSP contributions are tax-deferred; however, they are deducted during these computations. Additionally, in rare instances, if an employee has signed a pretax waiver for FEHB benefits, the benefits are considered to be taxable income and not used in these calculations.

To determine the amount of withholding, follow the steps listed below:

1. Determine normal biweekly gross wages from earnings statement.

2. Determine normal biweekly TSP contributions from earnings statement.

3. Determine normal biweekly FSA contributions from earnings statement. If applicable, add the amounts from both the FSA Dependent Child (FSADC) Sub-Account and the FSA Health Care (FSAHC) Sub-Account.

4. Determine normal biweekly FEHB pretax employee contribution from earnings statement (abbreviated as HP).

5. Determine normal CPP employee contribution from earnings statement. Note: This program is administered on a monthly basis. The CPP contribution is deducted in every second PP.

6. Determine normal Federal Employees Dental and Vision Insurance Program (FEDVIP) employee contribution from earnings statement.

7. Multiply the number of exemptions claimed by the new biweekly exemption value of $134.62 (withholding allowance). The federal tax line on the earnings statement shows the number of exemptions claimed (e.g., S1 = Single with One Exemption, M3 = Married with Three Exemptions).

8. Subtract the amounts in Step 2 (TSP), Step 3 (FSA), Step 4 (FEHB), Step 5 (CPP), Step 6 (FEDVIP), and Step 7 (Exemptions) from Step 1 (biweekly gross wages). The remainder is the amount that is subject to withholding.

9. Determine which range this amount falls into on the Federal Income Tax Withholding Table, and follow the instructions listed in the table.

The following is an example of how to compute federal income taxes for a Federal Employee Retirement System (FERS) employee who claims Married with Three Exemptions, and makes pretax contributions to the TSP, FSA, FEHB, CPP, and FEDVIP.

Example:

A FERS employee receives $3,668.76 as biweekly gross wages. The employee makes the following contributions: 11 per­cent of gross ($403.56) per PP to the TSP; $60.00 per PP to the FSADC Sub-Account; $90.00 per PP to the FSAHC Sub-Account; $130.56 per PP for FEHB ($130.56 is the actual cost for a Postal Service employee paying for High Option Self and Family (Category One) with the GEHA Benefit Plan); $100.00 for this PP to the CPP; and $43.00 for the GEHA PPO High Option Dental Biweekly Premium (Rating Region 2). The employee claims Married with Three Exemptions (M3 on the Federal Tax line of the earnings statement). Using the information provided above in the Federal Income Tax Withholding Table, fed­eral taxes are computed as follows:

 

1. Total biweekly gross wages	$3,668.76
2. TSP contributions	403.56
3. FSADC contribution	60.00
FSAHC contribution	90.00
Total FSA contribution	150.00
4. FEHB contribution	130.56
5. CPP contribution	100.00
6. FEDVIP contribution	43.00
7. Exemptions (3 x $134.62)	403.86

Computation continues as follows:

 

Biweekly gross wages	$3,668.76
Minus TSP contributions	-403.56
Minus FSA contributions	-150.00
Minus FEHB contributions	-130.56
Minus CPP contributions	-100.00
Minus FEDVIP contributions	-43.00
Minus exemptions	-403.86
Amount of wages subject to withholding	$2,437.78

To complete the computation, refer to the Married/Biweekly segment of the Federal Income Tax Withholding Table. The amount of wages subject to withholding, $2,437.78, falls within the “over $906 but not over $2,775” range. Using the infor­mation provided within that range, the final computation is as follows:

 

Amount subject to withholding	$2,437.78
Subtract $906 from $2,437.78	1,531.78
Multiply $1,531.78 by .15 (15%)	229.77
Add from the table	59.80
Add $229.77 and $59.80	289.57
Total federal income tax* that should be withheld from this employee’s biweekly check	$289.57

*Rounding may vary this total by a few cents.
