Most candidates think the 'Calculation of the Paycheck' section is a math test. It's not. It's a priority test, and getting the sequence of deductions wrong costs you more points than any rounding error ever could. The exam is designed to trap you on the order of operations, not simple arithmetic.
These free CPP practice questions cover paycheck calculations, including federal income tax withholding, FICA, voluntary and involuntary deductions, and gross-ups. This domain accounts for about 20% of the exam and tests your ability to apply complex statutory rules in the correct sequence, a critical skill for passing.

Calculation of the Paycheck Practice Questions (2026)
Answer each question before reading the explanation. Be honest with yourself.
Question 1
An employee earns $95,000 annually and is paid biweekly. In November, they have already earned $90,000 year-to-date. The 2026 Social Security wage base limit is $172,800. The Social Security tax rate is 6.2% and the Medicare tax rate is 1.45%. What is the total FICA tax withheld from their next paycheck?
This question tests your foundational understanding of FICA taxes without the complication of the wage base limit.
- Step 1: Calculate the biweekly gross pay.
$95,000 ÷ 26 pay periods = $3,653.85
- Step 2: Check if the Social Security wage base limit is a factor.
The employee's YTD earnings ($90,000) plus this paycheck's gross ($3,653.85) equals $93,653.85. This is well below the $172,800 limit for 2026. Therefore, the entire gross pay is subject to both Social Security and Medicare.
- Step 3: Calculate Social Security tax.
$3,653.85 × 6.2% = $226.54
- Step 4: Calculate Medicare tax.
$3,653.85 × 1.45% = $52.98
- Step 5: Calculate total FICA tax.
$226.54 (Social Security) + $52.98 (Medicare) = $279.52
Question 2
An employee is single with no dependents and has a completed 2026 Form W-4 with only entries in Step 1 and Step 5. They are paid $2,000 semimonthly. Using the Percentage Method for Automated Payroll Systems (from IRS Pub 15-T), what is the federal income tax withholding for one pay period?
(Use these illustrative 2026 tax brackets and adjustments from the semimonthly table for a single employee with a standard W-4):
- Wages are reduced by $581.25 before applying brackets.
- 10% on adjusted wages up to $468.75
- 12% on adjusted wages over $468.75 up to $1,908.33
- The tax is $46.88 plus 12% of the excess over $468.75.
This question tests your ability to apply the IRS percentage method tables, a core payroll function.
- Step 1: Determine the adjusted wage amount.
For a standard W-4, you must reduce the gross pay by the standard adjustment amount found in the IRS tables before applying the tax brackets. Gross pay = $2,000.00 Standard adjustment amount (given) = $581.25 Adjusted wage for withholding = $2,000.00 − $581.25 = $1,418.75
- Step 2: Apply the tax brackets to the adjusted wage.
The adjusted wage of $1,418.75 falls into the 12% bracket (over $468.75 but not over $1,908.33). The tax calculation for this bracket is a base amount plus a percentage of the excess. Base tax for the bracket = $46.88 Excess amount over bracket floor = $1,418.75 − $468.75 = $950.00 Tax on excess amount = $950.00 × 12% = $114.00
- Step 3: Sum the base tax and the tax on the excess.
Total withholding = $46.88 + $114.00 = $160.88
Question 3
An employee has biweekly gross pay of $1,500. They contribute 5% to a pre-tax 401(k). A court has ordered a creditor garnishment to be withheld. For this calculation, assume total mandatory tax deductions (FIT, FICA, SIT) are $285. What are the employee's disposable earnings for the purpose of this garnishment?
This question tests a critical legal definition: "disposable earnings." Getting this wrong invalidates the entire garnishment calculation.
- Step 1: Define disposable earnings under the CCPA.
The Consumer Credit Protection Act (CCPA) defines disposable earnings as an employee's gross earnings minus any amounts required by law to be withheld. These are mandatory deductions: federal, state, and local taxes, Social Security, and Medicare.
- Step 2: Identify what is NOT a mandatory deduction.
Voluntary deductions, such as 401(k) contributions, health insurance premiums, or union dues, are not subtracted from gross pay to determine disposable earnings.
- Step 3: Calculate disposable earnings.
Gross Pay: $1,500.00 Mandatory Deductions (given): $285.00 Disposable Earnings = $1,500.00 − $285.00 = $1,215.00
Question 4
Continuing with the employee from Question 3 (biweekly disposable earnings of $1,215), what is the maximum creditor garnishment that can be withheld from their paycheck under the CCPA? (Assume the higher of federal, state, or local minimum wage is $7.25/hour).
This question tests the two-part CCPA limit for creditor garnishments. You must calculate both limits and apply the one that is more favorable to the employee (the lesser amount).
- Step 1: The Percentage Limit.
The CCPA limits garnishments to 25% of the employee's disposable earnings. Limit 1 = $1,215.00 × 25% = $303.75
- Step 2: The Minimum Wage Limit.
The second limit is the amount by which disposable earnings exceed 30 times the applicable minimum wage per week. Since the employee is paid biweekly, we must use 60 times the minimum wage. Protected Amount = 60 × $7.25 = $435.00 Limit 2 = Disposable Earnings − Protected Amount = $1,215.00 − $435.00 = $780.00
- Step 3: Apply the lesser of the two limits.
The two potential garnishment amounts are $303.75 (Limit 1) and $780.00 (Limit 2). The law requires you to withhold the lesser amount to protect the employee. Maximum garnishment = $303.75
Question 5
An employer wants to give an employee a net bonus of exactly $2,000. The employee is below the Social Security wage base limit and has supplemental wages under $1 million for the year. The employer uses the optional flat rate for federal withholding. The employee's tax rates are: Federal = 22%, State = 5%, Social Security = 6.2%, Medicare = 1.45%. What is the gross amount of the bonus the employer must pay?
This is a classic gross-up calculation. You must use a specific formula to find the gross amount that results in the desired net pay after all taxes are withheld.
Step 1: Sum all applicable tax rates.
- Federal Supplemental Rate: 22%
- State Income Tax: 5%
- Social Security Tax: 6.2%
- Medicare Tax: 1.45%
- Total Tax Rate: 22% + 5% + 6.2% + 1.45% = 34.65% or 0.3465
Step 2: Calculate the net percent.
This is the portion of each dollar the employee keeps.- Net Percent = 100% − Total Tax Rate = 1 − 0.3465 = 0.6535
Step 3: Calculate the gross-up amount using the formula.
- Gross Pay = $2,000 ÷ 0.6535 = $3,060.29
To verify: $3,060.29 × (1 - 0.3465) = $3,060.29 × 0.6535 = $1,999.99 (Net Pay).
Question 6
An employee is paid $8,000 monthly. As of October 31, her year-to-date earnings are $168,000. The 2026 Social Security wage base limit is $172,800. What is the Social Security tax withholding for her November paycheck?
This question tests your ability to apply the Social Security wage base limit when it is crossed mid-paycheck.
- Step 1: Determine how much room is left before hitting the wage base limit.
SS Wage Base Limit: $172,800 YTD Earnings before this paycheck: $168,000 Remaining Subject Wages = $172,800 − $168,000 = $4,800
- Step 2: Compare remaining subject wages to the current paycheck's gross pay.
The employee's gross pay is $8,000. Since this is more than the remaining subject wages of $4,800, only $4,800 of this paycheck is subject to Social Security tax.
- Step 3: Calculate the Social Security tax.
Social Security Tax = $4,800 × 6.2% = $297.60
Question 7
An employee, filing single, earns $250,000 annually and is paid semimonthly. What is the Additional Medicare Tax withheld from one semimonthly paycheck, assuming their YTD earnings have already exceeded the $200,000 threshold?
This question tests your knowledge of the Additional Medicare Tax, which applies to high earners.
- Step 1: Recall the Additional Medicare Tax rules.
The tax is 0.9% on wages paid in excess of a threshold. The threshold for a single filer is $200,000. The employer is required to begin withholding this tax in the pay period when wages exceed the threshold.
- Step 2: Calculate the semimonthly gross pay.
$250,000 ÷ 24 pay periods = $10,416.67
- Step 3: Calculate the Additional Medicare Tax.
Since the employee's YTD earnings are already over $200,000, the entire gross pay for this period is subject to the tax. Additional Medicare Tax = $10,416.67 × 0.9% = $93.75
Question 8
An employee with biweekly disposable earnings of $1,000 is subject to a child support order. The employee supports a second family. Under the CCPA, what is the maximum amount that can be withheld for child support?
This question tests the specific, higher garnishment limits for child support orders under the CCPA. These limits are different from those for creditor garnishments.
- Step 1: Recall the CCPA limits for child support.
- 50% of disposable earnings if the employee is supporting another spouse or child.
- 60% of disposable earnings if the employee is NOT supporting another spouse or child.
- These limits increase to 55% and 65%, respectively, if the employee is more than 12 weeks in arrears.
- Step 2: Apply the correct limit based on the facts.
The employee supports a second family, so the 50% limit applies. The question does not state they are in arrears.
- Step 3: Calculate the maximum withholding.
Maximum Withholding = $1,000 (Disposable Earnings) × 50% = $500
