What steps should I take to close the year?

2.Complete any necessary 2013 Payroll reports.
3.Make a backup of the data.
4.Install the 2013 Canadian Payroll Year-End Update/2014 Tax Update.
5.Complete the "Year End File Reset" process.
6.Make a backup of the data.
7.Create the T4, T4A, and RL-1 statements, and print the T4, T4A, and RL-1 reports.
8.Edit the T4, T4A, and RL-1 records as necessary.
9.Create T4, T4A, and RL-1 Summary records.
10.Print the T4, T4A, RL-1 reports and create T4, T4A and RL-1 XML file, if appropriate.

Key Points to remember:

1.When you do the year end close it moves all your current year data into the Last Year (LY) tables and it doesn't take the date into consideration. For this reason it is very important that you complete ALL 2013 Payrolls (step 1) and then complete at least through the year end file reset (step 5) before doing any 2014 payrolls.
2.It is vital to do your install before the Year End Reset (Steps 4 and 5) because you are prompted during the Year End Reset to update Basic Personal Amounts. If you miss this you will need to restore from a backup.
3.When you do the year end file reset it changes the Basic Personal Amounts for employees. Depending on the Province it will either add a fixed amount or increase the amount by an indexation factor as determined by the Provincial Authority.
4.The 2013 Quebec Software number is not yet available but when it is issued you can find it on the Year End Release found in the Resources below.
5.Be sure to make backups when indicated in the complete steps.
