How to use these questions

Practise each short answer aloud, then add a case of your own: the size of the payroll, what went wrong or changed, what you did, and the result. Change every detail that could point to a person. Many payroll interviews add a short test: work out a net pay from a payslip, or find the errors in a payroll report.

What a payroll specialist is expected to know

Gross-to-net

Walk me through gross-to-net for one employee.

What they check: that you know every step of a payslip and the order they come in.

Short answer: "I start with gross pay: base salary, plus overtime, bonuses, allowances and taxable benefits, less unpaid leave. From that come the employee's social security contributions and the income tax withheld. What is left is net pay. Some items come off after that, such as a court order or a staff loan. On top, the employer pays its own share of social security, which never shows in the employee's net pay."

The full answer: Each country decides what counts as pay for tax and what counts for social security, and the two are not always the same: a company car or a meal allowance may be taxed differently from salary. Social security usually stops at a ceiling of earnings, so a high earner pays a smaller share. Tax depends on data the employee or the tax office gives: the German tax class in Germany, the tax code from HMRC in the UK, the W-4 form in the US. The total cost of an employee is gross pay plus the employer's contributions, and finance needs that figure too.

A weak answer: "The system calculates it." Follow-up: "The employee got a pay rise but their net pay barely changed." Check the tax band, a ceiling crossed, or a benefit that ended the same month.

An employee starts on the 12th of the month and gets a signing bonus. How do you work out the first payslip?

What they check: part-month pay and one-off payments, two common sources of mistakes.

Short answer: "I pay the salary for the days worked, using the method the contract or the company's policy sets, such as calendar days or working days. The bonus is a one-off payment; many countries tax it differently from regular pay, so I enter it as a one-off, not as salary. Then I check the tax and social security data the new employee gave us is in the system before the run."

The full answer: Use one method for part months across the company and write it down, so two people get the same answer. In Germany, a bonus is taxed as a one-off payment with its own German method, and it can move the employee above a social security ceiling for that month. In the US, a bonus may be withheld at a flat federal rate as supplemental wages. If the start comes after the cut-off date, the first pay may come next month with a correction, and the employee should hear that before payday, not after.

A weak answer: "I just add the bonus to the salary." Follow-up: "The tax data of the new hire is missing." Most countries then make you withhold at a higher default rate until the data arrives; tell the employee why.

Tax and social security, country by country

Which deductions does a payroll in Germany take, and where do they go?

What they check: that you know the German deductions by name and who receives them.

Short answer: "A German payroll takes Lohnsteuer, the German wage tax, with the solidarity surcharge for high earners and church tax for church members, and pays it to the tax office with a monthly return. It also takes the employee's half of the Sozialversicherung, German social security: pension, unemployment, health and long-term care insurance. The employer adds its own share and accident insurance, and pays it all to the employee's health insurance fund."

The full answer: The tax data come from the tax office electronically, so the tax class and allowances update without paper. Each new hire, leaver and change is reported to the health insurance fund under the German reporting rules, the DEÜV in Germany. Contributions are due near the end of the same month in Germany, before many companies have even run payroll, so the amount is often estimated and corrected next month. Minijobs, the German small jobs, have their own lower contributions and a monthly earnings limit.

A weak answer: "Tax and insurance, the system does it." Follow-up: "An employee leaves the church." The tax office changes the data, and church tax stops from the next month once the system receives it.

How do PAYE and National Insurance work in the UK?

What they check: the UK basics, and the real-time reporting that makes UK payroll different.

Short answer: "PAYE, Pay As You Earn, is how UK employers take income tax from each pay, using the tax code HMRC gives for each employee in the UK. National Insurance is the UK social security contribution, paid by the employee and, at a different rate, by the employer. Every pay run is reported to HMRC in the UK on or before payday through Real Time Information, RTI for short, in a full payment submission."

The full answer: The UK tax year runs from 6 April to 5 April. A tax code tells the payroll how much pay is tax-free and adjusts for benefits or underpaid tax; an emergency code is used until the right one arrives. Student loan repayments, workplace pensions under auto-enrolment and statutory sick pay run through the same payroll. HMRC in the UK must be paid the tax and National Insurance by the 22nd of the following month when paid electronically.

A weak answer: "PAYE is the payroll." Follow-up: "An employee says their tax code is wrong." Only HMRC can change it in the UK: the employee contacts HMRC, and the payroll applies the new code when it arrives.

What does a US payroll withhold at federal and state level?

What they check: the layers of US payroll: federal, state and sometimes local.

Short answer: "At federal level, income tax based on the employee's W-4 form, and FICA: the Social Security and Medicare taxes in the US, which the employer matches. The employer alone pays federal unemployment tax, FUTA in the US. At state level, most US states add their own income tax withholding, a few have none, and each state has its own unemployment tax and sometimes disability insurance."

The full answer: The US Social Security tax stops at a yearly wage base, while the Medicare tax has none and adds an extra rate for high earners. An employee who lives in one US state and works in another may owe tax to both, with rules on which comes first. Federal deposits follow a schedule set by the size of the payroll, and Form 941 reports them to the IRS each quarter in the US. Overtime rules under the US federal FLSA decide who is paid extra for hours over 40 a week.

A weak answer: "The US just has income tax." Follow-up: "An employee moves from Texas to California." Update the work and home state: California has state income tax, Texas has none.

What must a payroll in India deduct and report?

What they check: the Indian statutory deductions and the returns that go with them.

Short answer: "A payroll in India deducts the provident fund, PF, under the EPFO in India, usually a share of basic wages from employee and employer alike; ESI, the Indian Employees' State Insurance, for employees below its wage limit; professional tax in the states that charge it; and TDS, the income tax deducted at source in India, which is paid to the government and filed in a quarterly return."

The full answer: The employee chooses between the old and the new tax regime in India, and the TDS follows that choice. Form 16, given to each employee after the year in India, shows the salary and the tax deducted. From April 2026 India's new Income-tax Act replaces the 1961 Act, with new section numbers for the same work. India's labour codes, in force since November 2025, count most allowances above half of total pay back into wages, which raises PF where basic pay was kept low.

A weak answer: "PF and tax, the provider handles it." Follow-up: "An employee joins from another company." Ask for the previous employer's salary and TDS for the year in India, so the yearly tax is right.

What is different about running payroll in Switzerland?

What they check: the Swiss social insurances and the tax taken at source for foreign staff.

Short answer: "A Swiss payroll deducts AHV, the Swiss old-age and survivors' insurance, together with disability insurance and income compensation, shared half and half with the employer; unemployment insurance, also shared; accident insurance; and the employee's share of the occupational pension under the Swiss BVG. Swiss income tax is usually paid by the employee directly, except for many foreign workers, for whom the employer deducts Quellensteuer, the Swiss tax at source."

The full answer: The Swiss Quellensteuer rates differ by canton and by the person's family situation, and the employer reports and pays it to the canton. Family allowances are paid through the payroll too. At year-end every employee gets the Lohnausweis, the Swiss yearly statement of earnings for the tax return, and the employer sends a yearly wage declaration to the AHV compensation fund in Switzerland.

A weak answer: "It is like Germany, but in francs." Follow-up: "An employee lives in France and works in Geneva." Cross-border workers follow special rules in Switzerland, which depend on the canton and the treaty with France.

Year-end

What are your year-end tasks in payroll?

What they check: that you plan the busiest weeks of the payroll year and know their deadlines.

Short answer: "I reconcile the whole year: the payroll totals against the ledger and against what was reported and paid to the authorities. Then the yearly statements for employees and the yearly reports for the authorities, each with its deadline, and the new rates and ceilings for the next year, loaded and tested before the first run of January."

The full answer: The forms differ by country: the Lohnsteuerbescheinigung in Germany, sent to the German tax office by the end of February; the W-2 for each US employee and the IRS by 31 January in the US; the P60 for each UK employee by 31 May after the UK tax year, and the P11D for benefits in the UK; Form 16 in India; the Lohnausweis in Switzerland. Plan the year-end in the autumn, clean the master data before December, and keep a checklist of every step with an owner and a date.

A weak answer: "Year-end is just the December payroll." Follow-up: "A December bonus was approved after the last run." Decide with finance whether it is paid in a special run before year-end or in January, because the tax year it falls in changes the forms.

Payroll systems

Which payroll systems have you used, and how do you check what they calculate?

What they check: real experience with a system, and that you never trust its result blindly.

Short answer: "I have run payroll in DATEVPayroll software of many tax firms and mid-sized companies: master data, monthly runs and reports. Lohn, common in German companies and tax firms, and worked with SAPSAP HCM and its payroll in large companies: infotypes, payroll runs and the posting to finance. HCM in a large group. Many international groups use ADP or Workday. Whatever the system, I compare each run with last month: total gross and net, people paid, and every employee whose net pay changed by more than a set amount, and I check those cases one by one."

The full answer: A system calculates from its master data and its rules. The master data, such as salary, tax data, bank account and cost centre, is where most errors start, so changes need a second person's check. The rules, such as the yearly rates, come with updates from the vendor; test them before the first run of a new year. In SAP HCM the data sits in infotypes and a simulation run shows the result before the real one. Keep the reports of each run, because an auditor or an employee may ask years later. Small companies often use LexwareSimple payroll and accounting software for small companies, often run by one person..

A weak answer: "I trust the system; it is certified." Follow-up: "The new rates were not loaded in January." Rerun or correct in the next run, tell the employees affected, and fix the update check for next year.

How would you move a payroll to a new system?

What they check: that you can run a payroll project without risking a single payday.

Short answer: "I plan it as a projectRun a system change or a new country's payroll to a plan with tests and a parallel run. with a fixed go-live month, clean the master data first, and map every pay element from the old system to the new one. The key step is the parallel run: at least two months where both systems calculate the same payroll and I compare every payslip until the differences are explained. Only then does the new system pay people."

The full answer: Pick a go-live at the start of a tax year or a quarter, so the year-end forms do not come from two systems. Move the year-to-date figures for each employee as well as the master data. Test the interfaces: time recording in, payments and the ledger out. Train the team before go-live, and keep the old system readable for the years the law requires.

A weak answer: "We switch over at the end of the month." Follow-up: "The parallel run shows differences in a few payslips." Explain each one before go-live; an unexplained difference is a future error.

Accuracy and controls

An employee says their net pay is wrong. What do you do?

What they check: that you handle an error calmly, find its cause and treat the person well.

Short answer: "I thank them, take the details and promise an answer by a set time, usually the same day. Then I compare the payslip with last month and with the inputs: hours, absences, changes, tax data. If we made a mistake, I correct it, with an off-cycle payment if the amount matters to them, and explain it in plain words."

The full answer: Most complaints have a simple cause: a late change, an absence entered twice, new tax data. Explain the payslip line by line; often the pay is right and the employee had not expected a deduction. If it is an error, find out whether others are affected and fix the cause, not only the case. Keep a log of errors and their causes; it shows which checks to add.

A weak answer: "It will be fixed next month." For someone who cannot pay their rent, a month is too long. Follow-up: "The mistake was in the HR data, not in payroll." Fix it with HR, and agree a check so it cannot happen again.

Which controls stop payroll errors before payday?

What they check: the habits that make payroll accurate month after month.

Short answer: "A cut-off date for changes, so the run starts from complete data. The four-eyes principle: one person enters a change, another checks it. A comparison with last month that flags big changes in net pay. A check of the bank file against the payroll before release. And a reconciliation of the payroll to the ledger and to the tax and social security payments after each run."

The full answer: Split duties: the person who changes bank details should not also release the payment. Look for leavers still paid and new bank accounts changed just before payday, two classic signs of fraud. Reconcile each month, not only at year-end, so a difference is small and easy to trace. Write each control down with its owner, because an internal audit or an auditor will ask for proof that it ran.

A weak answer: "I am careful, so I do not need checks." Follow-up: "The team is short-staffed this month." Keep the four-eyes checks on bank details and the payment file, and move other work.

You find that an employee was overpaid for six months. How do you handle it?

What they check: fairness to the employee, the rules of the country and the fix of the cause.

Short answer: "I work out the exact amount, gross and net, and the tax and social security involved. I tell my manager and HR, then the employee, in person or by phone first, with a written summary. We agree a fair way to pay it back, often in instalments, within the law of the country and the contract. And I fix whatever caused it."

The full answer: Recovering an overpayment follows national law: limits on what may be deducted from pay, and time limits on claims, differ by country. Correct the tax and social security reports for the months concerned, or for the current year, as the country's rules ask. Never take back the whole amount from one payslip without agreement; it can leave the employee unable to live.

A weak answer: "We deduct it all next month; it was their money anyway." Follow-up: "The employee has already left." Write to them with the amount and a proposal, and take advice before any legal step.

Employee data

What employee data may a payroll team hold, and who may see it?

What they check: that you treat payroll data as some of the most sensitive data in a company.

Short answer: "In the EU, under the GDPR, payroll may hold the data it needs to pay people and meet the law: contract, salary, bank account, tax and social security data, absences. Access is limited to the payroll team and the people who need a part of it. Payslips go to the employee only, and records are deleted when the legal retention period ends."

The full answer: Some payroll data is a special category under the EU GDPR and needs extra care: health data behind sick pay, and in Germany church membership, which church tax reveals. Send payroll files only through secure channels, never as open email attachments. A payroll provider processes the data on the employer's behalf, so in the EU it needs a written data processing agreement. Outside the EU, the UK has its own version of the rules, Switzerland its data protection act, and India its new data protection law.

A weak answer: "Managers can see their team's salaries in the payroll system." Follow-up: "A team leader asks for a list of the team's salaries." Check what the role needs: often a total cost for the budget is enough, not each person's pay.

Senior payroll specialist, payroll manager, head of payroll and HR operations

These questions come up for senior payroll specialist, payroll manager, head of payroll and HR operations roles, where the work becomes planning, people and providers.

As payroll manager, how do you plan the payroll year and the team?

What they check: that you can run payroll as a calendar of fixed dates, with people who can cover each other.

Short answer: "I build a calendar of every payday, cut-off, report and payment for each country, plus the yearly peaks: year-end, the pay review, bonus months. I plan the team around it: no holidays in the peak weeks, and every payroll known by at least two people. Each run has a checklist, and I review the controls and the errors each month."

The full answer: Lead the teamLead a payroll team: plan the year, share the work, review the runs and train people. with clear owners per country or per company, and a rotation so knowledge is shared. Measure what matters: accuracy, deadlines met, questions answered on time. Plan the yearly changes of law with HR and finance before they hit the payroll. Report payroll cost and its trends to finance each month.

A weak answer: "Everyone knows their own payroll best, so I let them run it." Follow-up: "Your most experienced person resigns a month before year-end." Use the checklists and the second owner, and bring in short-term help early.

As head of payroll or HR operations, when would you outsource payroll, and when bring it in-house?

What they check: at the top of the ladder, judgement about cost, risk and control.

Short answer: "Outsourcing helps where we have few employees in a country, or where the rules are hard to keep up with: a provider brings the know-how and the system. In-house makes sense where we have many employees, complex pay or need fast changes. Either way, the company stays responsible, so I keep the controls, the data and someone who understands the payroll."

The full answer: Compare the full cost over several years: fees, the people still needed to send inputs and check results, the system, and the cost of errors. Check the provider's service levels, its security, its data protection and how a move away would work. In a group, a single provider for many countries gives one view of payroll; local providers often know the rules better. Review the choice every few years.

A weak answer: "Outsourcing means payroll is no longer our problem." Follow-up: "The provider made the same mistake three months in a row." Escalate with the service agreement, ask for the cause and a fix, and check the next runs yourself.
