Is CPTL approved by the Canada Revenue Agency (CRA)?

CPTL is based entirely on CRA's published guidelines for payroll deductions in it's publication T4127 - Payroll Deductions Formulas for Computer Programs. It is not CRA's policy to approve or certify independant software provider's implementations of their guidelines. We have tested CPTL extensively and are confident of it's compliance with CRA's requirements.
