What a payroll provider handles
- Calculating gross-to-net pay, deductions, overtime, bonuses and leave pay.
- Payslips and year-end forms for employees.
- Payroll tax and social security filings and payments to the authorities.
- Pension or retirement plan deductions, and benefits.
- Starters, leavers, and statutory payments such as sick and parental pay.
- Reports for your accountant and your general ledger.
Payroll rules differ by country
- United States: federal, state and sometimes local income tax withholding, FICA, and filings such as Form 941 and Form W-2.
- United Kingdom: PAYE through Real Time Information (RTI) reporting to HMRC on or before each payday, National Insurance, and workplace pension auto-enrolment.
- European Union: each country sets its own income tax and social security rules, and many have collective agreements that affect pay.
- Elsewhere: check whether you need a local entity or a local registration before you can run payroll at all.
If you want to employ someone in a country where you have no company, an employer of record may be the simpler route.
Types of payroll service
- Payroll bureau: a specialist runs payroll for you each period.
- Software plus support: you run payroll in cloud software, with expert help on hand.
- Global payroll aggregator: one provider coordinates payroll across several countries through in-country partners.
- Employer of record (EOR): a provider legally employs your staff abroad and runs their payroll.
- PEO (mainly US): a co-employment arrangement that bundles payroll, benefits and HR.
Questions to ask a payroll provider
- Which countries and states do you cover directly, and which through partners?
- Who is responsible if a filing is late or wrong?
- What are the cut-off dates each pay period?
- How do you secure employee data, and where is it stored?
- Does it connect with our HR and accounting software?
- What does it cost per employee, per run and for year-end?

What affects the cost
Pricing usually depends on headcount, pay frequency, the number of countries, and extras such as benefits administration or year-end work.
