Canadian Payroll Deduction Types

Search and filter Beanflow's system deduction catalog. Pre-tax runtime follows the actual Factor A mapping — RRSP, RPP, PRPP, and union dues — not every pre-tax catalog label.

Last updated August 2026

48 system deduction catalog rows

This is the current system catalog, including PRPP and the two precise union-dues reporting types. Catalog metadata is not the same as automatic runtime. Only RRSP, RPP, PRPP, and union dues have a dedicated Factor A path that can lower the income-tax withholding base.

Professional dues stay in the pre-tax catalog for reference and do not automatically reduce withholding. Employer-only rows and Quebec rows are catalog/reference — not a claim that Beanflow already runs those programs end to end.

How to read this table

  • Pre-tax runtime is actual Factor A mapping in DeductionProcessor: RRSP, RPP, PRPP, and union dues. A pre-tax catalog label is not enough.
  • T4 (2026) is published only where the verified annual reporting policy proves a box. Stale catalog t4_box values are not shown.
  • Employer-only and Quebec rows describe catalog classification, not finished automatic runtime.
