How do I know what the employee's Provincial/Territorial TD1P Total Claim Amount is?

All employees are required to file a Provincial/Territorial TD1(P) form with their employer. The Total Claim Amount will be the amount shown on this form, as claimed by the employee. If the employer does not have a Provincial/Territorial TD1(P) form on file for the employee, then the default Basic Claim Amount (Claim Code 1) should be used for payroll deduction calculations.
