### Calculate Social Security and Medicare withholding

• 2010 FICA rates: – Social Security wage base as January 2010 \$106,800 – Maximum social security an employee would pay in 2010 - \$6,622 (\$106,800 * 6.2%) – Medicare has no wage base (all wages are subject to the 1.45% tax) – Employers must match the amount of FICA tax deducted from each employee’s wages.

### Calculate Social Security and Medicare withholding

• • • For Social Security tax, multiply gross earnings per pay period times 6.2% on the first \$106,800 earned.

For Medicare tax, multiply gross earnings per pay period times 1.45% Social Security tax plus Medicare tax equals FICA withheld

Find the federal income tax withholding using the percentage method • Frank Rodriguez, married, claims for withholding allowances, and has weekly gross earnings of \$1,230

Four Steps Problem solving Plan

Clues Frank is paid weekly Action Plan Locate the withholding allowance for one person Frank claims 4 withholding allowances Multiply the single withholding allowance by the number of allowances Frank’s gross earnings are \$1,230 Frank is married Solve \$70.19

\$70.19 X 4 = \$280.76

Subtract the amount allowed for withholding allowances from Frank’s gross earnings \$1,230 - \$280.76 = \$949.24

\$20.70 + 15% over \$471 Find the MARRIED person section Subtract \$471 from Frank’s net gross earnings of \$949.24

\$949.24 - \$471 = \$478.24

Multiply 15% times the amount over \$471 Add the base withholding \$20.70 to the 15% \$478.24 X 15% = \$71.74

\$20.70 + \$71.74 = \$92.44

### Find the federal income tax withholding using the wage bracket method

• • • Based on a person’s total gross earnings, marital status, and number of allowances claimed Form W-4 (Employee’s Withholding Allowance Certificate) Withholding Tax Table

### Find the state income tax withholding

• • • Seven states do not have state income tax – Alaska, Florida, Nevada, South Dakota, Texas, Washington, and Wyoming State income tax is collected by withholding Example: – Terri Adams has gross earnings for the month of \$3,100. If her state has a 4.5% income tax rate, find the state withholding tax.

• \$3,100 X 0.045 = \$139.50
