For the 2025 tax year, this update has removed the RL-1 tax form mappings for boxes L-11, L-12, and L-13 which are used for security option deductions. Instead, employers should use Box L-9 for non-CPCC security option deductions and Box L-10 for Canadian-controlled private corporation (CCPC) security option deductions. For the 2024 tax year, mappings for boxes L-11, L-12 and L-13 are still active for amendment filings. If you've created custom tax compliance rules in Payroll Setup > Earnings and Deductions that are mapped to boxes L-11, L-12, and L-13, you must update the mapping in these rules. System tax compliance rules that are currently mapped to boxes L-12 and L-13 are automatically updated to use boxes L-9 or L-10. |
