Answer

The home payroll continues to pay the employee while the host payroll reports the same compensation and remits local tax. The obligation sits on the payer, and the payer is liable for what it failed to withhold.

What the employer owes

The home payroll continues to pay the employee while the host payroll reports the same compensation and remits local tax. Reconciling the two — and the equalisation entries between them — is what keeps both filings defensible.

The carve-out

Shadow payroll pays nobody. It exists so the host country receives the withholding and reporting it is owed on compensation paid somewhere else.

Shadow payroll — what does the employer owe?
ItemAmount
Annual salaryC$120,000
Working days in the year220
Days worked in the other country102
Days worked at home118
Income sourced to the other countryC$55,636
Income sourced at homeC$64,364

C$55,636 is sourced abroad on this split, which is the figure the host country taxes and the figure the home credit is computed on. Reproduce this from a travel record, not from memory — it is the first thing an auditor asks for.

An illustration, not a client file. The sums are chosen for legibility and the thresholds are stated for the example alone — nothing reaches a filing until it has been confirmed at source for your own year.

Your next step

The full treatment — who it binds, the deadline, the penalty and the fixed fee — is on Shadow payroll. One call now is worth more than a filing season of guessing.

Cross-border tax case studies

Case study 1

Standing up a host payroll record for a seconded engineer

An engineer was sent to work at a group company abroad while remaining on the home payroll and the home bank account. The host country had a claim on the compensation from the first reporting period. We registered the host reporting, established which elements of the package were taxable locally, and set the periodic host reporting to mirror the home payments. Nothing changed in what the employee received. The engagement produced a host registration, a period-by-period reconciliation between the two records, and a written note of which package elements were reported where and on what basis.

Case study 2

Reconciling two payroll records that reported different compensation totals

A company running both a home and a host record for the same assignee found the two reporting different annual totals. Allowances had been added to one and not the other, and a currency conversion had been applied at the wrong date. We rebuilt the compensation from the underlying payment records, restated both sides to a single total, and identified which periods needed correcting in which country. The engagement produced a reconciled compensation statement for the assignment year, corrected host reporting for the affected periods, and a monthly control that compares the two records before either is filed.

Case study 3

A host record opened late and backdated to the arrival date

An assignee had been working abroad for most of a year before anyone raised host reporting. We fixed the arrival date from travel records, established which reporting periods had already closed, and filed them in order so the host account was brought current rather than started from the present. The home record was then restated to match. The work produced the completed host filings for the closed periods, a schedule of the interest and penalty exposure for the employer to decide on, and a trigger in the mobility process so registration precedes the first host reporting period.

Case study 4

Extending host reporting to a bonus received following repatriation

An assignee returned home and was paid an annual bonus afterwards, part of which related to the period worked abroad. The host record had already been closed. We reopened the reporting, apportioned the award between host and home working by reference to the underlying service period, and reported the host portion where it belonged. The home treatment was then aligned so the same amount was not taxed twice without relief. The engagement produced a reopened and corrected host filing, an apportionment working paper tied to the service period, and a rule for when the host record may be closed.

Case study 5

Reporting an equity award that vested during a host assignment

An employee's award vested while they were working abroad, and the whole gain had been reported at home. We established the service period the award related to, split it between host and home working days from the travel record, and reported the host portion through the host payroll record with tax withheld and remitted locally. The home reporting was restated so relief could be claimed against the same income. The engagement produced a sourced apportionment of the award, corrected reporting in both countries, and a note of how the employer will treat future vesting during assignments.

Case study 6

Posting policy entries to both payrolls so the cycle balanced

A company had been deducting a hypothetical home tax from an assignee and bearing the host tax, but only the home record carried the entries. The host reporting therefore understated compensation, because employer-borne tax is itself compensation in the host country. We ran the gross-up cycle to a settled result, posted the entries to both records, and restated the host reporting for the periods affected. The engagement produced a balanced set of policy entries across the two payrolls, corrected host filings, and a closing reconciliation the employer can repeat at each year end.

Putting a Foreign Hire on a Canadian Payroll

The obligation sits on the payer, and the payer is liable for what it failed to withhold. Registration, the residence question and any treaty exemption are settled before the first pay run rather than after.

One Employee Working From Another Country

A single remote employee can create payroll registration, withholding and social security obligations in their country, and sometimes a corporate presence too. The review sets out each obligation and the order they have to be registered in.

Core International & Cross-Border Tax Services

International Tax Planning & Advisory

Strategy and compliance for income, assets and families spread across borders.

One coordinating team: filings on every side of the border are sequenced so treaty relief and foreign tax credits are claimed once — and in the right country.

U.S. & Cross-Border Tax Returns

Dual filers: U.S. citizens in Canada and Canadians with U.S. income run two parallel systems — we prepare both, in the right order, every year.

Expat & Emigration Tax

The move year is its own project: the elections and valuations filed that year decide the next decade of both countries’ returns.

Non-Resident Canadian Tax

Default withholding is 25% of gross: elective returns routinely turn over-withheld rent and pensions into refunds.

Transfer Pricing & BEPS

Documentation prepared with the return is the cheapest insurance in international tax; reconstructing it during an audit is the most expensive.

Cross-Border Estates & Trusts

Wills drafted for one country routinely misfire in the other — deemed disposition here, estate tax there, credits in between.

Cross-Border Corporate Tax

Expansion raises the same four questions every time — entity, PE, repatriation, payroll. We answer them before the tax authorities do.

India Tax for NRIs & Returning Residents

The deduction is taken on the sale price, not the gain — which is why an NRI property sale strands cash unless the certificate is applied for before closing.

Canadian Tax with a Foreign Element

Residency is decided on facts, not on a form — and the year you arrive or leave is the one where the largest amounts turn on the smallest details.

UAE Tax for Expats & Their Home Country

A zero-tax country is only half the answer — the question that decides the bill is whether the country you came from still treats you as resident.

Remote Workers & Digital Nomads

Working from anywhere doesn't mean taxed nowhere: residency defaults, employer payroll exposure and treaty relief decide where income actually lands.

Working from another country does not by itself end tax residence in the one you left, and it can start one where you are sitting. Day counts, ties, the employer's own exposure and the treaty tie-breaker all point at the same question, and the year you move is the year it has to be answered on paper.

Shadow payroll: further questions

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 moving money between my own accounts in two countries taxable?

Moving your own capital between your own accounts is not itself income, so the transfer is not what creates tax. What can create tax or reporting is the income the money earned before it moved, a foreign-exchange gain on certain holdings, and the reporting obligations the balances themselves trigger — foreign account and asset reports keyed to balances rather than income. Remittances out of some countries also need certification before the bank will send them. See foreign account reporting.

How much foreign income is tax-free in Canada?

None of it is tax-free for being foreign. A Canadian resident is taxed on worldwide income, so foreign salary, interest, dividends, rent and gains all go on the return, converted to Canadian dollars. What genuinely reduces the bill is the basic personal amount, the credit for foreign tax already paid, and any treaty article that exempts a specific type of income. The reporting thresholds people have in mind — the foreign property statement, for one — govern reporting, not exemption. See the foreign tax credit.
