What Is Shadow Payroll?
Shadow Payroll refers to a payroll reporting mechanism under which a host-country entity reports and withholds tax on pay delivered by a foreign employer.
Also known as: Shadow Payroll Reporting, Host-Country Shadow Payroll.
How Shadow Payroll works
Shadow Payroll applies when an employee works in a host country on assignment while remaining on the home-country payroll, and host-country withholding rules require local reporting, so a parallel payroll records the earnings, calculates host-country tax and social contributions, and reports them without paying the salary a second time. HMRC guidance, for example, makes a UK host employer responsible for recording and reporting the earnings and PAYE deductions of seconded employees who remain employed by an overseas employer. Where an expatriate is fully tax equalised, the employer may apply for a Modified PAYE arrangement under an EP Appendix 6 agreement. Triggers, thresholds and social security treatment vary by country, assignment length and totalisation agreement.
Shadow Payroll vs Employer of Record
Unlike an Employer of Record, which becomes the legal employer in the host country, Shadow Payroll leaves the original employment contract and salary payment unchanged and adds host-country reporting and withholding.
Example
Illustrative example: A company in Country A seconds an engineer to a subsidiary in Country B for two years and keeps paying the salary in Country A. The subsidiary runs a shadow payroll which mirrors the salary, computes Country B tax and remits the withholding, while Country A may grant relief under its double taxation rules.
Common misconception
Myth: An employee paid from the home country needs no payroll reporting in the country where the work is performed.
Reality: Host-country withholding and reporting duties can arise through Shadow Payroll even when salary is paid abroad, depending on local law and assignment facts.
Frequently asked questions
When is a shadow payroll required?
A Shadow Payroll is generally required when host-country law imposes withholding or reporting on employment income earned locally while the salary continues to be paid by a foreign employer, subject to treaty and local thresholds.
Does a shadow payroll mean the employee is paid twice?
A Shadow Payroll does not pay the salary twice; the host entity records the home-paid earnings for tax and social security calculation and remits the resulting withholding to the host tax authority.
