Schedule 8, Schedule 8Q, and RC381 Calculation Corrections

Note: All preparers are advised to update to 2024.4.1 or a more recent release and review their returns.

CRA identified an error in the original versions of their Schedule 8 (5000-S8), Schedule 8Q (5005-S8), and RC381.

During certain situations, the calculation on these forms may result in an underpayment of  base CPP/QPP and level 1 (ECPP1/EQPP1) contributions and an overpayment of level 2 (ECPP2/EQPP2) contributions where there is an overall underpayment.

This issue specifically impacted the calculation of line 22215 (Deduction for CPP or QPP enhanced contributions on employment income) on tax returns.

We have released an update to correct these forms. The following lines have been updated with revised instructions:

Schedule 8, Part 3, Line 38:

• Previous Instruction: "If line 25 is "0", enter the amount from line 24 (if any) and continue at line 43."
• Corrected Instruction: "If line 25 is positive or "0", enter the amount from line 24 (if any) and continue at line 43."

Schedule 8Q, Part 2, Line 37:

• Previous Instruction: "If line 25 is "0", enter the amount from line 24 (if any) and continue at line 42."
• Corrected Instruction: "If line 25 is positive or "0", enter the amount from line 24 (if any) and continue at line 42."

Schedule RC381:

• Previous Instruction: "If line 68 is "0", enter the amount from line 67 (if any) and continue at line 86."
• Corrected Instruction: "If line 68 is positive or "0", enter the amount from line 67 (if any) and continue at line 86."
