GST registrants that pay allowances to cover employees' expenses can claim an input tax credit (ITC) in the following situations:

• At least 90% of the expenses are taxable (zero-rated expenses are not included).
• The expenses are reasonable and were incurred in Canada in the course of the registrant's activities.
• The allowance is deductible (in whole or in part) in the calculation of the registrant's income for income tax purposes.

Employers can claim an ITC to recover the GST paid on expenses that they could have recovered as an ITC had they incurred the expenses themselves. In this case, the ITC is equal to 5/105 of the allowance paid, taking into account any restrictions on meal and entertainment expenses.

Likewise, QST registrants can claim an input tax refund (ITR) equal to 9.975/109.975 of the allowance paid to an employee for expenses incurred in Québec on which QST was paid, provided the allowance is deductible (in whole or in part) in the calculation of the registrants' income for income tax purposes. Employers can claim an ITR to recover the QST paid on expenses that would have given entitlement to an ITR had they incurred the expenses themselves.
