What is a shadow payroll and why do we need one?
A shadow payroll is a second payroll record in the host country that reports compensation the employee is actually paid somewhere else. It pays nobody. Its purpose is to put the host authority in the position it would be in if the employee were paid locally: the compensation is reported, local tax is withheld and remitted, and the local employer reporting is filed. You need one when an employee is working in a country whose rules give it a claim on their compensation, while the home entity carries on paying the salary into the home bank account.
Does the employee get paid twice under a shadow payroll?
No. Money moves once, through the home payroll, into the account the employee has always used. The host record reports the same compensation a second time for tax purposes only, and the host tax is withheld and remitted against it. What the employee sees is usually a deduction on the home payslip representing the host tax, or a settlement once the year closes, depending on how the policy is written. The two records have to reconcile to a single compensation total, because two different reported figures for one person is exactly what an examination looks for.
Which compensation has to be reported on the host payroll?
Start from everything the employee receives for the period of host working, not just base salary. Allowances, employer-provided housing, relocation items, tax the employer bears on the employee's behalf, and awards that vest while the person is working in the host country all belong in the analysis. Host rules decide which of them are taxable locally and on what basis, and the home rules may treat the same items differently. The reconciliation between the two is the deliverable: one compensation total, two tax treatments, both traceable to the same source records.
Who remits the host country tax if we pay from home?
The host reporting entity does, through the shadow record. The home company carries on making the actual payment, and the host registration exists so that the withholding and reporting the host country is owed are made there, on time, in local currency. Responsibility sits on the payer side rather than with the employee, and it is the payer that is pursued for tax that should have been withheld. Where no host entity exists, the arrangement usually needs a registration of its own before the first period can be reported at all.
How do equalisation entries flow through a shadow payroll?
The policy figures have to land in both records or neither balances. A hypothetical home tax deducted from the employee, the actual host tax the employer bears, and any settlement after the year closes are each compensation events in their own right, and the host record has to show them on the basis host rules require. The order matters: employer-borne tax is itself compensation, which increases the host tax, which increases the compensation again. Running that cycle once and posting the result to only one of the two payrolls is the commonest reconciliation failure.
When can we close a shadow payroll after an assignment ends?
Not on the day the employee flies home. The record has to stay open long enough to report anything still sourced to the host period: a bonus received following the departure, an award that vests afterwards but relates to host workdays, and the final policy settlement. Closing early means those items are reported nowhere, or reported only at home where the host country has a claim. The sequence is usually final host reporting, final reconciliation against the home record, then deregistration, with the working papers kept for the host examination window.
Is double taxation legal?
Yes. Nothing prevents two countries from taxing the same income under their own domestic law — each is exercising its own jurisdiction. What treaties and credit systems do is relieve the outcome rather than prohibit the charge, and relief is generally something you must claim on a return or a form, not something applied automatically. Miss the claim and the double charge stands. Double taxation explains the mechanism.
How do you avoid double taxation?
You claim relief once, in the right country, in the right order. Usually the source country taxes first, the residence country then gives a credit for that tax against its own charge on the same income, and a treaty caps the source-country rate. Getting the order wrong is what produces a double charge you then have to unwind. The mechanism differs by income type, which is why we map the whole position before filing either return.
