Sending Employees to Canada: Personal Tax and Payroll

Tax residence while working in Canada, withholding, the tax treaty

Scott Tang, CPAUpdated 2026-11-032026 rules6 min read

When a subsidiary first opens, the parent usually sends one or two key people over: a general manager, a finance lead, a technical lead. Where their pay is taxed, who withholds the tax, and which country's social security they pay into are the first three things to sort out for anyone sent to work in Canada.

183 days

The Canada–China tax treaty's short-stay threshold for ordinary employees (counted by calendar year); other conditions also apply

From day one

If the Canadian subsidiary bears the salary, it is generally taxable in Canada from the first day

2017

The Canada–China social security agreement took effect; with a Chinese certificate of coverage, employees can generally be exempt from CPP during the posting

First: is the employee a Canadian tax resident?

Item	Short-term posting, family stays in China (common case)	Long-term posting, family comes too (common case)
Canadian tax status	Commonly a non-resident	Commonly becomes a Canadian tax resident
What is reported in Canada	Only income from work in Canada	Worldwide income is reported in Canada
On the China side	Still a Chinese tax resident, reporting worldwide income in China	Depends on both countries' rules; if both treat the person as resident, the treaty's tie-breaker rules decide

The table shows only common cases. Residency has to be decided person by person, based on residential ties (where the person lives, where their family is, where their economic ties are), Canadian tax law and the tax treaty — not just on their visa and the number of days. Assess it before the person arrives: the first year's tax filing is completely different depending on the answer.

Second: does the 183-day rule apply?

Under Article 15 of the Canada–China tax treaty, the salary an ordinary employee earns working in Canada can be taxed only in China, but only if all three of these conditions are met:

No more than 183 days in Canada in the calendar year
Counted by calendar year; keep a record of every entry into and exit from Canada.
Paid by an employer outside Canada
The Chinese parent pays the salary and bears the cost. If the salary is recharged to the Canadian subsidiary or the subsidiary reimburses it, the CRA may treat the subsidiary as the real employer.
Not borne by the employer's establishment in Canada
If the parent has a branch or permanent establishment in Canada that bears the salary, this condition is not met either.

Senior managers (such as the general manager) and directors are a separate case. The Canada–China treaty has separate provisions for the pay of people holding top-level managerial positions in a Canadian company and for directors' fees. Canada can generally tax these, and the 183-day rule above does not apply. Mainland China and Hong Kong are covered by different agreements, so they also have to be looked at separately.

In practice, the salary of someone sent to run the subsidiary is almost always borne by the subsidiary, so the 183-day rule usually doesn't help — pay for work in Canada is taxable in Canada from the first day.

Whether the pay is ultimately exempt and whether tax must be withheld now are two separate questions. Even if the person is expected to be in Canada for less than 183 days and the pay would be exempt under the treaty, the employer generally still has to withhold tax as required (Regulation 102), unless it has applied to the CRA in advance for a waiver and the waiver has been approved. As a non-resident employer, the parent can also apply for non-resident employer certification. You can't skip withholding simply because you expect the stay to be under 183 days.

Third: who runs payroll?

The subsidiary pays the salary
The clearest option: the subsidiary withholds income tax, CPP and EI through its payroll account, issues a T4 at year-end, and the employee files a tax return in Canada.
The parent pays the salary in China
For the work done in Canada, there are usually still withholding and reporting obligations in Canada. A common approach is to run a "shadow payroll" in Canada and withhold as usual. Decide first whether the subsidiary or the parent will carry the withholding obligation, and agree on this with your accountant in advance.
Benefits count as pay too
Rent, a car, flights home, children's school fees and similar items paid by the company are mostly taxable benefits and must be included on the T4.

Social security: the Canada–China agreement

The Canada–China social security agreement took effect on January 1, 2017. An employee sent from China who obtains a certificate of coverage in China can, within the posting period the agreement allows, keep paying into China's pension insurance and be exempt from Canadian CPP, so contributions aren't paid in both countries. Note that the agreement covers only pensions (CPP). EI (Employment Insurance) is not covered by the agreement; whether EI has to be paid is decided separately under the EI rules. The period and conditions of a certificate of coverage are as issued by the authorities of the two countries.

If you file in both countries, don't pay tax twice

If the employee is still a Chinese tax resident, personal income tax paid in Canada can generally be claimed as a credit under Chinese rules; please confirm the details with your advisers in China. The key is to report on a consistent basis in both countries and keep the documents.

How Sheng Qian CPA can help

Plan before arrival
How long the posting lasts, whether family is coming, who pays the salary, whether the role is top-level management: we first assess tax residence and the treaty provisions, then set the payroll and withholding plan (applying for a waiver if needed).
Payroll in one place
The subsidiary's payroll account, source deductions and remittances, T4s, and handling the CPP certificate of coverage (for prices, see "What Sheng Qian CPA Can Do for Foreign Companies: Services from Set-Up to Day-to-Day Operations" in this series).
Employees' personal tax too
Canadian personal tax returns for the seconded employees themselves, with communication in Chinese and coordination with the parent's HR and finance teams.
