Canadian income tax can apply to pay for days worked in Canada, even when the treaty will exempt it in the end. We assess whether each employee fits a Regulation 102 waiver or your company fits non-resident employer certification, set up what’s needed, and keep day counts and T4 reporting on track.

Each employee who expects treaty relief can ask CRA to waive withholding on their Canadian pay. Apply about 30 days before Canadian work starts or the first payment. An approved waiver applies to payments from its approval date and covers only that employee.
A U.S. employer can apply once to stop withholding for qualifying employees, meaning treaty-exempt employees who work in Canada fewer than 45 days in the calendar year or are present fewer than 90 days in any 12-month period. Certification lasts up to two calendar years. The employer must track each employee’s days and still file T4 slips unless it reasonably expects an employee’s Canadian income to be CAN$10,000 or less. CRA can revoke certification if the conditions are not met.
Under the Canada–U.S. tax treaty, a U.S. resident’s pay for work in Canada is generally exempt from Canadian tax if either it is CAN$10,000 or less for the year, or the employee is in Canada no more than 183 days in any 12-month period and the pay is not paid or borne by a Canadian employer or a Canadian permanent establishment. Any day or part of a day in Canada counts, including vacation days.
A treaty exemption doesn’t stop withholding by itself. The employer keeps withholding until CRA approves a waiver or certification.

No. The pay must also not be borne by a Canadian employer or permanent establishment, unless the employee earns CAN$10,000 or less. Even when the treaty exempts the income, withholding continues until CRA approves a waiver or certification.
No. An R102-R waiver is employee-specific. Employer certification can cover qualifying employees, but each one’s days must be tracked.
Certification suits employers with repeated short trips, where each employee stays under 45 working days in the calendar year or under 90 days present in any 12-month period. Longer or one-off assignments that are still treaty-exempt usually use individual R102-R waivers.
At least 30 days before the employee starts working in Canada or before the first payment. Late requests may still be considered, but relief generally applies only from approval.
For the treaty’s 183-day test, any day or part of a day you’re physically in Canada counts, regardless of the hours, and even vacation days in Canada are included.
Up to two calendar years. CRA can revoke it if the conditions aren’t met, and the employer may then owe the withholding for the certified period.
Generally yes. A certified employer still reports qualifying employees on T4 slips unless it has no reason to believe an employee’s Canadian income for the year will be more than CAN$10,000.
No. Those have separate rules and possible exemptions, such as a U.S. certificate of coverage for CPP.
You need a CRA business number, and if you expect to make remittances, a payroll program account. We can register both.
Québec has its own source-deduction and employer-contribution rules, which a CRA waiver or certification doesn’t address. We’ll flag what applies.
Review payroll now. CRA may still consider a request, but relief generally applies only after approval.
Yes. That’s Regulation 105, which applies to the business’s fee, not employees’ pay. See Regulation 105 waivers.
