Best practice

Use the employee’s work location (where they ordinarily report) for GST/HST rate.
Choose dates or days available (either method works).
Enter kilometres accurately—this drives the reduction test.
Keep a PDF/CSV export with payroll files for audit support.

Step-by-step

Enter basics: Prepared by, preparation date, and tax year.
The tax year also sets the default GST/HST reporting date.
Select work location & GST/HST registration:
If Not registered, the GST/HST section is hidden because Line 105/103 is not applicable.
GST/HST options (if registered):
- Include operating-cost benefit in deemed tax = GST/HST base is standby + operating.
- Unchecked = GST/HST base is standby only.
- Report in period ending defaults to the period that includes the last day of February of the following year (editable).
Ownership cost (Owned by employer):
- Cost of automobile should include GST/HST and options; exclude trade-in allowances.
- Add any post-purchase additions (incl. tax).
Availability (most important):
- Enter Start/End dates OR Days available.
- The calculator converts to 30-day periods (days ÷ 30). You can override periods if needed.
- Enter any employee reimbursement for availability to reduce the standby charge (not below zero).
Kilometres: Enter any two of Total / Business / Personal and the third will auto-fill.
Reduced standby eligibility test:
- Business use must be ≥ 50%, and
- Personal kilometres must be ≤ 1,667 × (30-day periods).
If eligible, the Results panel will show both Base and Reduced standby calculations.
Optional operating-cost benefit: Use the per-km rate method, less any operating reimbursements.
You can include/exclude this amount from the GST/HST base using the checkbox in GST/HST options.

GST/HST extraction note

The calculator extracts embedded tax using rate ÷ (1 + rate): 5/105, 13/113, 15/115, etc. The amount shown as “GST/HST to report” is the same extracted tax portion.

Reminder: This calculator is for guidance only and does not replace CRA rules. Standby charge cannot be negative; operating-cost benefit may be reduced to zero but not below. Employers must be GST/HST registered to report Line 105/103, and ITC eligibility depends on the facts and CRA guidance.
