T4127-JAN Payroll Deductions Formulas for Computer Programs - 103rd Edition - Effective January 1, 2016

Notice to the reader

Since the Guide T4127 – Payroll Deductions Formulas for Computer Programs was only published on December 8, 2015, employers will not face penalties for failing to withhold.

The CRA recognizes that these income tax changes will be implemented on a best-effort basis where practical, in full appreciation of the different payroll systems and administrative capacities of employers.

Employers are encouraged to discuss these changes with affected employees.
