50 free Payroll trivia questions with answers — trivia quiz, new questions added Aug 2026.
42 free payroll trivia questions with answers. This payroll trivia quiz is written for payroll and HR teams, National Payroll Week events, office quiz nights and anyone curious about where a paycheck's numbers come from. It covers the mechanics (gross versus net, FICA rates, W-2 and W-4 forms, pay frequencies, garnishment limits, FUTA), the history (the 1938 minimum wage, withholding in 1943, the first Social Security number and first monthly benefit check, the Bundy time clock) and the industry (ADP, Paychex, PAYE in the UK). A few questions wander further afield: why 'salary' comes from salt, how company scrip trapped coal miners, and which country funds a third of its budget from payroll tax. Difficulty runs from things every employee half-knows to details only a payroll professional will get. Every answer was checked against a reference page and each question carries the sentence that supports it.
