RATIONALE:

To provide employees at Indiana University a guide to calculate Federal taxes withheld for contract pay on paychecks based on the annualized method used at Indiana University for tax withholding.

PROCEDURES:

Departments should follow these steps to calculate the amount of federal tax withholding on compensation paid to a contract employee (i.e. those employees paid as part time adjunct faculty or student academics).

Please note that withholding for each contract agreement is considered without regard to any other contracts agreements the individual may have at the time - unless the individual’s multiple contract agreements contain the exact same number of days.

Steps

Example

1. Determine the monthly pay amount and the number of days in the contract:

a. Divide the contract amount by the number of payments the individual will receive, or

b. Use the monthly payment amount, if known.

c. Count the days between the contract start and end dates.

1. An individual is on a $20,000 contract paid in 5 monthly installments from 8/1/2016 to 12/7/2016. The monthly pay amount is $4,000. The number of days in the contract is 129 (31+30+31+30+7)

2. Annualize the monthly pay amount:

a. Divide the number of days in the contract by 365

b. Multiply by 12. This is the number of periods in the contract.

c. Multiply the monthly pay amount by the number of periods in the contract.

2. Annualized pay

a. 129 ÷ 365 = 0.3534

b. 0.3534 × 12 = 4.2411

c. $4,000 × 4.2411 = $16,964.40

3. Subtract the appropriate number of withholding allowance based on the most current submitted W-4 from the annualized pay . For tax year 2016, the withholding allowance amount can be found in Table 5 from IRS Publication 15 . One allowance equals $4,050. The result is taxable income .

3. The individual has completed form W-4 as a single taxpayer with one allowance and no additional withholding.

$16,964.40 - $4,050.00 = $12,914.40

4. Find the taxable income amount on the appropriate section of the tax rate table . Follow the instructions on the table to calculate the annual tax amount . The tax rate table can be found in Table 7 from IRS Publication 15 (Dec., 2015).

4. $12,914.40 is between $11,525 and $39,750, so the annual tax amount is…

$12,914.40 - $11,525.00 = $1,389.40
$1,389.40 × 15% = $208.41
$208.41 + $922.50 = $1,130.91

5. Divide the annual tax amount by the number of periods in the contract, then add any additional withholding. The result is the amount of tax withholding per pay period.

5. $1,130.91 ÷ 4.2411 = $266.65

Additional Examples

Contract Pay Withholding Example 1

1. Determine the monthly pay and the number of days in the contract

1. Monthly pay = $2,000
Days in Contract = 127 (31+29+31+30+6)

2. Annualize the monthly pay amount:

a. Divide the number of days in the contract by 365

b. Multiply by 12. This is the number of periods in the contract.

c. Multiply the monthly pay amount by the number of periods in the contract.

2.  

a. 127 ÷ 365 = 0.3479

b. 0.3479 × 12 = 4.1753

c. $2,000 × 4.1753 = $8,350.60

3. Subtract the appropriate number of withholding allowance based on the most current submitted W-4 from the annualized pay . For tax year 2014, the withholding allowance amount can be found in Table 5 from IRS Publication 15 (Dec.,2015). One allowance equals $4,000. The result is taxable income .

3. $8,350.60 - $4,050.00 = $4,300.60

4. Find the taxable income amount on the appropriate section of the tax rate table . Follow the instructions on the table to calculate the annual tax amount . The tax rate table can be found in Table 7 from IRS Publication 15 (Dec., 2015).

4. $4,350.60 is less than $8,550.00 so no tax will be withheld. If the employee determines that she will owe tax when she completes her tax return, she may request additional withholding on Form W-4.

Contract Pay Withholding Example 2 With Additional Witholding Amount

1. Determine the monthly pay and the number of days in the contract

1. Monthly pay = $2,000
Days in Contract = 304 (31+30+31+30+31+31+28+31+30+31)

2. Determine the annualized pay amount:

a. Divide the number of days in the contract by 365.

b. Multiply by 12. This is the number of periods in the contract.

c. Multiply the monthly pay amount by the number of periods in the contract.

2.  

a. 304 ÷ 365 = 0.8329

b. 0.8329 × 12 = 9.9945

c. $2,000 × 9.9945 = $19,989

3. Subtract the appropriate number of withholding allowance based on the most current submitted W-4 from the annualized pay . For tax year 2016, the withholding allowance amount can be found in Table 1 from IRS Publication 15 (Dec., 2015). One allowance equals $4,050. The result is taxable income .

3. $19,989 - $4,050 = $15,939

4. Find the taxable income amount on the appropriate section of the tax rate table . Follow the instructions on the table to calculate the annual tax amount . The tax rate table can be found in Table 7 from IRS Publication 15 (Dec., 2015).

4. $15,989 is between $8,600 and $27,050 so the annual tax amount is…

$15,939 - $8,550 = $7,389.00
$7,389 x 10% = $738.90
$=738.90

5. Divide the annual tax amount by the number of periods in the contract, then add any additional withholding. The result is the amount of tax withholding per pay period.

5. $738.90 ÷ 9.9945 = $73.93
$75.93 + $100.00 = $173.93
