Notice to the reader:
Please note that the revised Quebec Parental Insurance Plan (QPIP) information is now included in this version.
We have redesigned Guide T4127, Payroll Deductions Formulas for Computer Programs
The January 2013 edition will make it easy to see what has changed and to find information on specific topics. The major changes to the guide are:
- The "What’s new for January 1, 2013?" section includes a complete list of the changes that affect the formulas in the guide.
- A detailed definition for each factor can be found in "Chapter 4 - Glossary." More information will be provided under the specific situations, as required.
- "Chapter 9 - Summary sheets" gives you old and new figures. The first summary sheet has the figures for 2013. The second sheet has the figures for 2012. The summary sheets will show you which figures have changed and you can use it a reference to compare both years.
- We have removed some of the information that you can find in other publications, as well as the examples for options 1 and 2.
