Remote Employee Province of Employment Calculator
An employee working from home in a province where you have no office is not automatically taxed there. The answer turns on where your establishments are and whether a full-time remote work agreement exists. Work out the province, the tax table, the EHT base, the board that covers them, and what a year of getting it wrong costs to fix.

Disclaimer: The province of employment determines which provincial payroll deduction tables and which provincial TD1 an employer applies, and it is reported in box 10 of the T4 slip. Where an employee physically reports for work at an establishment of the employer, the province of employment is generally the province of that establishment. Where an employee does not physically report for work at an establishment, the Canada Revenue Agency has since 2024 applied an administrative approach under which, if a full-time remote work agreement is in place, the employee may be considered attached to an establishment of the employer, assessed first by whether the employee would reasonably be expected to attend that establishment were it not for the agreement, and then by secondary indicators including where the employee attends meetings, receives instructions and supplies, and to whom they report. An employee’s own home is not an establishment of the employer. Where no establishment can be identified, the province of employment is generally taken to be that of the establishment from which the employee’s pay is administered. Ontario employer health tax applies to remuneration paid to employees who report for work at, or are paid from, a permanent establishment of the employer in Ontario, and other provinces impose their own payroll levies on differing bases; workers compensation coverage is administered separately by each province’s board and generally follows where the worker is based rather than the province of employment for income tax. The rates used here for employer health tax, other provincial payroll taxes and workers compensation premiums are editable defaults that should be replaced with the current published figures for your own situation, and exemptions, thresholds and maximum insurable earnings that may apply are not modelled. The correction figures are illustrative estimates of professional and administrative cost rather than a quotation. This page is general information, not tax or payroll advice.
The Employee’s Home Is Not Your Office
The instinct is that someone living in Vancouver must be taxed as a British Columbia employee. That is not how the rule works. The province of employment follows an establishment of the employer, and an employee’s spare bedroom is not an establishment of yours no matter how long they work there.
So a company with one office in Ontario and staff scattered across the country can quite properly be applying Ontario tax tables to all of them. What decides it is where your establishments are, not where your people sleep.
This changed in 2024. Before then the treatment of employees who never attend an office was unsettled, and many employers defaulted to the employee’s home province. The current approach asks a different question, and a payroll set up under the old assumption may have been wrong every pay period since.
First Question: Do They Physically Report Anywhere
If the employee physically reports for work at one of your establishments, the province of employment is the province of that establishment. Someone living in Ottawa who drives to your Gatineau office is a Quebec employee for payroll purposes, however few days they do it.
Only when there is no physical reporting at all does the second test come into play, and that is where the remote work agreement matters.
Second Question: Which Office Are They Attached To
Where the employee never attends an establishment and a full-time remote work agreement is in place, they are treated as attached to one of your establishments. The primary indicator is simple: which office would they have gone to if the agreement did not exist?
Where that is not clear, secondary indicators are weighed. Where do they attend meetings, in person or otherwise. Where do they receive their instructions and their equipment. Who supervises them and where does that person sit. The answers usually point at one office.
| Situation | Province of Employment |
|---|---|
| Physically reports to an establishment | Province of that establishment |
| Never attends, remote agreement, attached to head office | Province of the head office |
| Never attends, remote agreement, attached to a local office | Province of that local office |
| Never attends, no agreement | Falls back to where pay is administered |
| No establishment identifiable at all | Generally where pay is administered |
The agreement is worth having in writing. The attachment test is built around a full-time remote work agreement, and an arrangement that exists only as a verbal understanding is harder to rely on when someone asks how the province was determined. Putting it in writing costs nothing and is the difference between a documented position and a recollection.
EHT and Workers Compensation Do Not Follow the Same Rule
This is where employers get caught out. Having settled the province of employment for income tax, it is tempting to apply it to everything else. The other two obligations run on their own tests.
Ontario employer health tax reaches remuneration paid to employees who report for work at a permanent establishment of the employer in Ontario, or who are paid from one. Other provinces impose their own payroll levies on their own bases, and some impose none at all.
Workers compensation is administered province by province and generally follows where the worker is actually based. An employee working in British Columbia is likely covered by that province’s board rather than by WSIB, regardless of which tax table their pay is calculated on.
So one employee can be on Ontario tax tables, in the Ontario EHT base, and registered with another province’s compensation board at the same time. That is not a contradiction; it is three separate regimes each answering their own question. Treating them as one is the most common error in a distributed payroll.
What It Costs to Have It Wrong
Using the wrong province means the wrong tax table and the wrong provincial TD1, so the amounts withheld are wrong. The employee’s own return generally sorts their side out, since they file by their province of residence at year end.
The employer’s side does not self-correct. Box 10 on every affected T4 is wrong, which means amended slips. The provincial payroll tax base may have been understated or overstated. And where a compensation board should have been receiving premiums and was not, that board’s registration and premium history has to be put right, sometimes with interest.
What This Calculator Does Not Cover
- Quebec’s separate payroll regime, which adds QPP, QPIP and its own remittances
- EHT exemptions and thresholds, and the associated employer rules that reduce them
- Maximum insurable earnings for workers compensation premiums
- Employees who split time across several provinces in a single year
- Non-resident employees or those working outside Canada
- Whether a location amounts to an establishment, which is a question of fact
A distributed payroll is worth reviewing once, properly. Our payroll help and support service covers the province determination for each employee, the remote work agreements, the EHT base, board registrations and any amended T4s the review turns up.
