20 Payroll interview questions

Hiring the right payroll staff is crucial for the financial health of your business. 

Payroll clerks and specialists process and manage employee payments, verify timesheets, calculate wages, handle tax deductions, and answer employees payroll-related questions. For all this, they need a keen eye for detail, excellent communication skills, and the right technical knowledge to support employees and the organization effectively.

When hiring payroll staff, you need to evaluate candidates’ skills accurately and objectively to find the best fit. Resumes and certifications give you an idea of applicants’ qualifications but don’t reveal their actual payroll and accounting knowledge, time management, or problem-solving skills.

The best way to build a skills-first hiring process and hire top candidates is to combine pre-employment skills testing with targeted payroll interview questions. Use Attention to Detail, Accounting, and Microsoft Excel tests to evaluate candidates’ skills – and then invite the best ones to an interview.

Below, you’ll find the best interview questions to ask future payroll staff, along with sample answers and guidelines to help you evaluate answers.

Top 20 payroll interview questions to hire the best candidates

1. What is payroll?

• Answer: Payroll refers to the process by which employers pay their employees for the work they have performed. It involves calculating wages, withholding taxes, and ensuring that all necessary deductions are made.

2. How often should employees be paid?

• Answer: Pay frequency can vary depending on company policy, employee contracts, or local regulations. Common pay periods include weekly, bi-weekly, semi-monthly, or monthly.

3. What information is required to process payroll?

• Answer: Key information includes employee personal details (e.g., name, address, and social security number), hours worked, pay rate, tax withholding information (W-4), and any deductions (benefits, retirement contributions, garnishments).

4. What is the difference between gross pay and net pay?

• Answer: Gross pay is the total earnings before any deductions are made (such as taxes, insurance, or retirement contributions), while net pay is the amount the employee takes home after all deductions.

5. What deductions are typically taken from an employee’s paycheck?

• Answer: Common deductions include federal and state income tax, Social Security, Medicare, retirement contributions, health insurance premiums, and other benefits or garnishments.

6. How do you calculate overtime pay?

• Answer: Overtime is typically paid at 1.5 times the employee’s regular hourly rate for any hours worked over 40 in a workweek (for non-exempt employees). Some states or contracts may have different overtime rules.

7. What is FICA, and how does it impact payroll?

• Answer: FICA (Federal Insurance Contributions Act) is a U.S. law that mandates payroll tax deductions for Social Security and Medicare. Employees contribute 6.2% for Social Security and 1.45% for Medicare, and employers match these amounts.

8. What is the purpose of a W-2 form?

• Answer: A W-2 form reports an employee’s annual wages and the taxes withheld. It is filed with the IRS and given to employees each year to be used for tax returns.

9. What is the purpose of a W-4 form?

• Answer: A W-4 form is filled out by employees to indicate their tax withholding preferences. This determines how much federal income tax is withheld from their paychecks.

10. How do I handle paid time off (PTO) on payroll?

• Answer: PTO is typically accrued based on company policy (e.g., hours worked or length of service). When employees take PTO, they are paid as if they were working, and the amount is deducted from their accrued balance.

11. What is the difference between an exempt and non-exempt employee?

• Answer: Exempt employees are not entitled to overtime pay and typically receive a salary. Non-exempt employees are eligible for overtime pay (typically 1.5x regular pay for hours over 40 per week) and can be hourly or salaried.

12. What are the payroll taxes that an employer is responsible for paying?

• Answer: Employers are responsible for paying the employer’s portion of Social Security (6.2%), Medicare (1.45%), and federal unemployment tax (FUTA). Additionally, some states may have their own unemployment tax.

13. How do you handle bonuses and commissions in payroll?

• Answer: Bonuses and commissions are typically included in the employee’s paycheck and are subject to payroll taxes. The amount is added to the employee’s gross income and taxed accordingly.

14. What is the difference between independent contractors and employees?

• Answer: Independent contractors work on a contractual basis and are not considered employees. They are responsible for their own taxes, whereas employees have taxes withheld by the employer. Independent contractors typically receive a 1099 form instead of a W-2.

15. What should be included in a pay stub?

• Answer: A pay stub should include the employee's gross pay, deductions (taxes, benefits, etc.), net pay, pay period dates, year-to-date totals, and employer information.

16. How do I report payroll taxes to the IRS?

• Answer: Employers must report payroll taxes using IRS forms such as Form 941 (quarterly) and Form 940 (annual unemployment tax report). Taxes are submitted to the IRS through electronic funds transfer or other payment methods.

17. How do I handle payroll for employees working in multiple states?

• Answer: Employees working in multiple states may need to have state income taxes withheld for each state in which they work. Employers must comply with each state’s tax laws, which may include registration with each state’s revenue agency.

18. What is the IRS Form 941, and why is it important?

• Answer: Form 941 is the Employer’s Quarterly Federal Tax Return. It reports the amount of federal income tax, Social Security, and Medicare taxes withheld from employees’ wages, as well as the employer’s contributions.

19. How do I handle garnishments or wage deductions?

• Answer: Garnishments or wage deductions must be withheld according to court orders or government directives (e.g., child support, tax levies). These deductions are taken from an employee’s paycheck and sent directly to the appropriate agency.

20. What is the role of a payroll service provider, and do I need one?

• Answer: A payroll service provider handles all aspects of payroll, including calculating wages, withholding taxes, filing tax forms, and ensuring compliance with labor laws. Small businesses may use them to save time and reduce errors, while larger companies often have in-house payroll departments.
