个税 Tax Installment - which province r u in?
In Quebec, Tax Installments are required when 1) CRA tax payable > $1800, and/or Revenu Quebec tax payable > $1800. We try to avoid the hassles to make installments to both level of governments by making bigger deductions (提前代扣) from our "regular incomes". Hence, after filing income tax, we get refunds from excess withholding taxes.
